What is the Present Simple?
The Present Simple is one of the most versatile tenses in English, used far beyond just describing present actions. It expresses facts, habits, routines, permanent situations, scheduled events, and even past events in storytelling. Unlike continuous tenses that focus on ongoing actions, the Present Simple presents actions and states as complete, general, or repeated truths. This tense forms the foundation of English communication and appears in contexts ranging from casual conversation to formal writing, scientific facts to sports commentary.
Opening examples:
– Water boils at 100 degrees Celsius. (scientific fact)
– The train leaves at 9:30 tomorrow morning. (scheduled future event)
– Shakespeare writes his first play in 1590. (historic present in narrative)
Mastering all uses of the Present Simple is essential for B1 learners because it appears in conditional sentences, time clauses, instructions, and numerous fixed expressions that native speakers use daily.
How to Form the Present Simple
The Present Simple has straightforward formation rules with one key variation for third-person singular subjects.
Affirmative Form:
– I/You/We/They + base verb: I work, they live, we eat
– He/She/It + base verb + -s/-es: he works, she lives, it eats
Spelling rules for third person:
– Most verbs: add -s (play → plays, run → runs)
– Verbs ending in -s, -sh, -ch, -x, -o: add -es (watch → watches, go → goes)
– Verbs ending in consonant + y: change y to -ies (study → studies, fly → flies)
– Have is irregular: has
Negative Form:
– I/You/We/They + do not (don’t) + base verb: I don’t work
– He/She/It + does not (doesn’t) + base verb: she doesn’t work
Question Form:
– Do + I/you/we/they + base verb?: Do you work?
– Does + he/she/it + base verb?: Does she work?
Note that the base verb is always used after do/does in negatives and questions—never add -s to the main verb in these forms.
When Do We Use the Present Simple?
The Present Simple serves multiple distinct functions in English, making it essential to understand each context:
1. Permanent and Long-term Situations:
We use the Present Simple for facts and situations that are generally true or last for extended periods. Example: “She lives in Madrid” (not temporary), “The Earth orbits the Sun” (permanent fact).
2. Habits and Routines:
For actions that happen regularly or repeatedly, often with frequency adverbs like always, usually, often, sometimes, rarely, never. Example: “I drink coffee every morning,” “They visit their grandparents twice a month.”
3. General Truths and Scientific Facts:
For statements that are universally or generally true. Example: “Ice melts at 0°C,” “Cats sleep a lot,” “The sun rises in the east.”
4. Fixed Schedules and Timetables:
For future events that follow a fixed schedule (transport, cinema times, classes). Example: “The meeting starts at 3 PM,” “The film begins at 7:30,” “School finishes at 4 o’clock.”
5. State Verbs:
Verbs describing states rather than actions (believe, know, love, hate, want, need, prefer, understand, remember, belong, own, seem, appear) typically use Present Simple, not continuous. Example: “I understand the problem,” “She owns a restaurant.”
6. Instructions and Directions:
For giving step-by-step instructions or directions. Example: “You turn left at the traffic lights,” “First, you add the eggs, then you mix everything together.”
7. Sports Commentary and Demonstrations:
For live commentary or demonstrations happening now. Example: “Messi passes to Ronaldo, he shoots, he scores!” “Now I add the sugar and stir gently.”
8. Historic Present:
For dramatic storytelling, making past events feel immediate and vivid. Example: “So yesterday I walk into the office and my boss says…,” “In 1969, Neil Armstrong steps onto the moon.”
9. Time Clauses (after when, as soon as, before, after, until, while):
In clauses referring to future time, we use Present Simple, not future forms. Example: “I’ll call you when I arrive” (not ‘when I will arrive’), “We’ll start as soon as everyone gets here.”
10. Zero Conditional (general truths):
For cause-and-effect relationships that are always true. Example: “If you heat water to 100°C, it boils,” “When it rains, the streets get wet.”
11. First Conditional (real future possibilities):
In the ‘if’ clause of first conditional sentences. Example: “If it rains tomorrow, we’ll stay home,” “I’ll be happy if she passes the exam.”
12. Newspaper Headlines:
For recent past events in headlines to create impact. Example: “President visits flood victims,” “Company announces new product.”
Register and Formality
The Present Simple appears across all registers, but usage patterns vary by formality level.
Formal/Academic Register:
In formal writing, the Present Simple dominates for stating facts, research findings, and general truths: “This study examines…,” “The data shows…,” “Research indicates that stress affects health.” Scientific and academic texts rely heavily on Present Simple for timeless truths and established knowledge.
Neutral/Standard Register:
Everyday communication uses Present Simple for routines and facts: “I work in an office,” “The shop opens at 9 AM,” “We usually have dinner at 7 PM.” This is the most common register for describing regular activities.
Informal/Conversational Register:
Informal speech often uses Present Simple for storytelling (historic present) and immediate reactions: “So I go to the store and I see…,” “He says he doesn’t know.” Contractions (don’t, doesn’t, isn’t) are standard in casual contexts.
Professional/Technical Register:
Instructions, manuals, and procedures use Present Simple: “The system updates automatically,” “You press the red button to stop.” This creates clear, authoritative communication without personal involvement.
Comparing with Similar Structures
Understanding when to use Present Simple versus other tenses is crucial for accuracy.
Present Simple vs. Present Continuous:
Present Simple expresses permanent situations, habits, and general truths, while Present Continuous describes temporary actions happening now or around now. Compare: “I live in London” (permanent) vs. “I’m living in London” (temporary arrangement). “She works hard” (general characteristic) vs. “She’s working hard” (right now). State verbs (know, like, believe) typically use only Present Simple: “I know the answer” (not ‘I’m knowing’).
Present Simple vs. Present Perfect:
Present Simple focuses on regular actions or general time, while Present Perfect connects past actions to the present. Compare: “I read books” (general habit) vs. “I’ve read that book” (completed with present relevance). “He lives here” (current state) vs. “He’s lived here for five years” (duration from past to present).
Present Simple vs. Will Future:
For scheduled future events, Present Simple is preferred over ‘will’: “The train leaves at 6 PM” (timetable) rather than “will leave.” However, in time clauses with when/if/as soon as, Present Simple replaces future forms: “When he arrives, we’ll start” (not ‘when he will arrive’). Use ‘will’ for predictions and decisions: “I think it will rain” (not ‘it rains’).
Present Simple vs. Past Simple:
Present Simple can describe past events in historic present for dramatic effect: “So yesterday I walk into the room and everyone stops talking.” This makes narratives more immediate than Past Simple: “I walked into the room and everyone stopped talking.” However, for straightforward past reporting, Past Simple is standard.
Zero Conditional vs. First Conditional:
Both use Present Simple in the ‘if’ clause, but zero conditional uses Present Simple in both clauses for general truths: “If you heat ice, it melts.” First conditional uses Present Simple + will for real future possibilities: “If it rains, we’ll cancel the picnic.”
Common Collocations and Patterns
The Present Simple appears in numerous fixed patterns and collocations that B1 learners should recognize.
Frequency Adverbs:
Always, usually, often, sometimes, occasionally, rarely, seldom, never typically appear with Present Simple and position themselves before the main verb but after ‘be’: “She always arrives early,” “I never eat meat,” “They are usually busy on Mondays.”
Time Expressions:
Every day/week/month/year, once/twice a week, on Mondays, in the morning, at weekends: “We meet every Friday,” “He calls his mother twice a week,” “The office closes at 5 PM.”
Linking Words in Instructions:
First, then, next, after that, finally: “First, you turn on the computer, then you enter your password, finally you click ‘login’.”
Conditional Conjunctions:
If, when, unless, as soon as, before, after, until, while: “If you need help, ask me,” “I’ll wait until you finish,” “Call me as soon as you arrive.”
State Verb Patterns:
Know about/how to, believe in, belong to, depend on, consist of: “I know how to swim,” “This belongs to me,” “Success depends on effort.”
Opinion and Preference:
Think (opinion), believe, suppose, imagine, prefer, like, love, hate: “I think it’s a good idea,” “She prefers tea to coffee.”
Reporting Verbs:
Say, tell, report, claim, state, announce: “The article says that prices are rising,” “Experts claim that exercise improves health.”
Fixed Expressions:
“It depends,” “That reminds me,” “I suppose so,” “It doesn’t matter,” “That sounds good”: these common phrases always use Present Simple regardless of time context.
📝 Examples 25
Example 1
✓ The museum opens at 10 AM and closes at 6 PM every day except Monday.
This demonstrates Present Simple for fixed schedules and timetables. We use it for official opening hours because they follow a regular, unchanging pattern. The time expressions 'every day' and 'except Monday' reinforce the routine nature of this information.
Example 2
✓ Water freezes at 0 degrees Celsius and boils at 100 degrees Celsius at sea level.
This exemplifies Present Simple for scientific facts and universal truths. These physical properties are permanent and unchanging, making Present Simple the only appropriate choice. This use appears frequently in academic and scientific contexts at B1 level.
Example 3
✓ I usually wake up at 7 AM, have breakfast, and leave for work by 8:30.
This shows Present Simple describing daily routines and habits. The frequency adverb 'usually' signals regular occurrence. The sequence of actions (wake up, have, leave) all use Present Simple because they represent typical repeated behavior rather than one-time events.
Example 4
✓ She doesn't eat meat because she believes it's wrong to kill animals.
This combines two Present Simple uses: permanent lifestyle choice ('doesn't eat meat') and state verb expressing belief ('believes'). State verbs like believe, think, know, and understand almost always use Present Simple, not continuous, even when describing current mental states.
Example 5
✓ If you heat butter, it melts quickly.
This demonstrates zero conditional using Present Simple in both clauses. Zero conditional expresses general truths and cause-effect relationships that are always true. The structure 'if + present simple, present simple' shows a scientific or universally applicable fact rather than a specific future possibility.
Example 6
✓ The train to Manchester leaves at 15:45 from platform 3 tomorrow afternoon.
This illustrates Present Simple for scheduled future events, particularly transport timetables. Even though 'tomorrow afternoon' clearly indicates future time, we use Present Simple because the departure follows a fixed, official schedule. This is standard usage for trains, buses, flights, and cinema times.
Example 7
✓ When you arrive at the airport, call me immediately and I'll come to pick you up.
This shows Present Simple in a time clause with 'when' referring to future time. In clauses beginning with when, as soon as, before, after, until, we use Present Simple instead of will/future forms. The main clause uses 'I'll come' (future), but the time clause requires 'you arrive' (Present Simple).
Example 8
✓ First, you click on the icon, then you enter your username and password, and finally you press 'submit'.
This exemplifies Present Simple for giving instructions and directions. The sequence markers (first, then, finally) guide the reader through steps. Using Present Simple creates clear, direct instructions that sound authoritative and are typical in manuals, recipes, and procedural texts.
Example 9
✓ So I walk into the room yesterday and everyone just stares at me in complete silence.
This demonstrates the historic present, where Present Simple narrates past events to create immediacy and drama. Despite 'yesterday' indicating past time, using 'walk' and 'stares' instead of 'walked' and 'stared' makes the story more vivid and engaging, common in informal storytelling.
Example 10
✓ Ronaldo receives the ball, dribbles past two defenders, shoots from outside the box, and scores!
This shows Present Simple in live sports commentary. Even though actions happen in real time right now, commentators use Present Simple rather than Present Continuous to create rapid, punchy descriptions. This use captures the speed and excitement of live sporting events.
Example 11
✓ I know exactly what you mean, and I completely understand your frustration with the situation.
This illustrates state verbs (know, understand) using Present Simple. These verbs describe mental states rather than actions, so they don't take continuous forms. Other state verbs include believe, recognize, remember, prefer, love, hate, own, belong—all typically use Present Simple only.
Example 12
✓ The Earth revolves around the Sun, and the Moon orbits the Earth in approximately 27 days.
This demonstrates Present Simple for permanent facts about the natural world. These astronomical truths are timeless and unchanging, making Present Simple essential. This usage is fundamental in geography, astronomy, biology, and other sciences when stating established facts.
Example 13
✓ If it rains tomorrow, we'll cancel the picnic and go to the cinema instead.
This exemplifies first conditional structure using Present Simple ('rains') in the if-clause despite referring to future time. First conditional expresses real future possibilities. The if-clause always uses Present Simple, while the main clause uses will/won't to show the future consequence.
Example 14
✓ My brother works as an engineer in Berlin and travels internationally about twice a month.
This shows Present Simple for permanent situations and regular activities. 'Works' describes his ongoing profession (not temporary), while 'travels' with 'twice a month' indicates regular frequency. These long-term situations contrast with temporary arrangements that would use Present Continuous.
Example 15
✓ Cats sleep up to 16 hours a day, while dogs typically sleep only about 12 hours.
This demonstrates Present Simple for general truths about animal behavior. These statements describe typical characteristics rather than specific animals at specific times. The adverbs 'up to' and 'typically' reinforce that these are general patterns, not one-time observations.
Example 16
✓ I don't believe in ghosts, but my sister thinks they exist and refuses to watch horror films.
This combines multiple state verbs (believe, think, refuse) all using Present Simple. These verbs express mental states and attitudes that are current but not temporary actions. Notice how 'refuses' describes a consistent attitude rather than a single refusal.
Example 17
✓ The company announces record profits as shares rise to their highest level in five years.
This illustrates Present Simple in newspaper headline style, describing recent past events as if happening now. Headlines use Present Simple to create impact and immediacy. This journalistic convention makes news feel more current and relevant to readers.
Example 18
✓ Unless you study regularly, you won't pass the exam, so I suggest you start preparing now.
This shows Present Simple after 'unless' (meaning 'if not') in a conditional structure. Like other conditional conjunctions, 'unless' requires Present Simple even when referring to future situations. The main clause uses 'won't pass' (future), but the conditional clause needs 'you study' (Present Simple).
Example 19
✓ The course starts in September, runs for twelve weeks, and finishes just before Christmas.
This demonstrates Present Simple for scheduled future events in educational contexts. Course schedules, like transport timetables, use Present Simple because they follow fixed plans. The sequence of three verbs (starts, runs, finishes) all describe future events using Present Simple.
Example 20
✓ Every morning, I wake up, check my phone, make coffee, and read the news before work.
This exemplifies Present Simple describing a habitual morning routine. The time marker 'every morning' signals regular repetition. The sequence of four actions all use Present Simple because they represent daily habits rather than actions happening right now.
Example 21
✓ This book belongs to me, but that dictionary over there is yours if you need it.
This shows state verbs of possession (belongs, is) using Present Simple. 'Belongs' expresses ownership as a state, not an action, so it can't be continuous. Similarly, 'is' describes current possession. State verbs describing ownership, like own, possess, have (possession), always use Present Simple.
Example 22
✓ As soon as I finish this report, I'll send it to you and then we can discuss it.
This demonstrates Present Simple after 'as soon as' in a time clause about future events. Despite the future meaning, we use 'finish' (Present Simple) not 'will finish'. Time conjunctions (when, as soon as, before, after, until) require Present Simple in the dependent clause.
Example 23
✓ The sun rises in the east and sets in the west—this never changes regardless of season.
This illustrates Present Simple for permanent natural phenomena. These directional facts are universal and timeless truths. The addition of 'never changes' reinforces the permanent nature, though Present Simple alone would suffice for expressing this unchanging reality.
Example 24
✓ I always forget people's names at parties, but I never forget faces—it's really embarrassing.
This shows Present Simple with frequency adverbs (always, never) describing habitual tendencies. The position of 'always' and 'never' before the main verbs is typical. This use expresses consistent personal characteristics or repeated behaviors that define someone's typical experience.
Example 25
✓ Research shows that regular exercise improves mental health and reduces stress significantly.
This demonstrates Present Simple in academic/formal register for stating research findings and general truths. 'Shows', 'improves', and 'reduces' all use Present Simple because they express established knowledge and general cause-effect relationships. This usage dominates academic writing at B1 level and above.
⚠️ Common Mistakes 15
Mistake 1
❌ Incorrect: ❌ The train is leaving at 6 PM tomorrow, so we need to hurry.
✓ Correct: ✓ The train leaves at 6 PM tomorrow, so we need to hurry.
💡 Why: DIAGNOSTIC: This error occurs because learners overapply the rule that Present Continuous expresses future arrangements. However, for fixed timetables (trains, buses, flights, cinema times), Present Simple is required regardless of future time reference. The schedule is official and unchanging, not a personal arrangement. PREVENTION: Ask yourself: 'Is this a personal plan or an official timetable?' If it's published and fixed (transport, cinema, school schedule), use Present Simple even for future time.
Mistake 2
❌ Incorrect: ❌ When you will arrive, please call me immediately.
✓ Correct: ✓ When you arrive, please call me immediately.
💡 Why: DIAGNOSTIC: This common error stems from direct translation from languages that use future tense after time conjunctions, or from misunderstanding English future time expression. In time clauses with when, as soon as, before, after, until, while, English requires Present Simple even when meaning is future. The future meaning comes from the main clause context, not the time clause itself. PREVENTION: Memorize this rule: 'After time words (when/as soon as/before/after/until), never use will—always use Present Simple.' Check every sentence with these words.
Mistake 3
❌ Incorrect: ❌ I am knowing the answer to your question about the project.
✓ Correct: ✓ I know the answer to your question about the project.
💡 Why: DIAGNOSTIC: This error occurs because learners overgeneralize that 'right now' situations need Present Continuous. However, state verbs (know, understand, believe, like, love, hate, want, need, prefer, remember, belong, own) describe states, not actions, and almost never take continuous forms. These verbs express mental states or conditions that exist, not actions in progress. PREVENTION: Learn the list of common state verbs. Before using continuous, ask: 'Is this an action I'm doing, or a state that exists?' If it's a state (mental, emotional, possession), use Present Simple only.
Mistake 4
❌ Incorrect: ❌ If it will rain tomorrow, we will stay home and watch movies.
✓ Correct: ✓ If it rains tomorrow, we'll stay home and watch movies.
💡 Why: DIAGNOSTIC: This mistake happens because learners logically think 'tomorrow' requires future tense throughout the sentence. However, in first conditional sentences, the if-clause always uses Present Simple regardless of future meaning. Only the main clause uses will/won't. This is a fixed grammatical rule in English conditional structures. PREVENTION: Remember the first conditional formula: 'If + Present Simple, will + base verb.' Never put will in the if-clause. Check every conditional sentence to ensure the if-clause uses Present Simple, even when discussing future possibilities.
Mistake 5
❌ Incorrect: ❌ Water is boiling at 100 degrees Celsius at sea level.
✓ Correct: ✓ Water boils at 100 degrees Celsius at sea level.
💡 Why: DIAGNOSTIC: This error occurs when learners confuse specific current actions with general scientific facts. Present Continuous describes water boiling right now in a specific pot, but scientific facts about physical properties require Present Simple because they express permanent, universal truths, not temporary processes. The continuous form incorrectly suggests this is a temporary or ongoing observation. PREVENTION: Ask: 'Am I describing what's happening right now in one case, or stating a permanent fact that's always true?' For scientific facts, general truths, and universal properties, always use Present Simple.
Mistake 6
❌ Incorrect: ❌ She is living in Paris since 2015 and loves it there.
✓ Correct: ✓ She has lived in Paris since 2015 and loves it there. / She lives in Paris and has been there since 2015.
💡 Why: DIAGNOSTIC: This error combines two problems: using Present Continuous for permanent situations and using it with 'since' (which requires Present Perfect). Present Continuous with 'since' is grammatically impossible in standard English. For duration from past to present, use Present Perfect. For permanent current residence without emphasizing duration, use Present Simple. PREVENTION: When you see 'since' or 'for' with specific duration, automatically think Present Perfect, never Present Continuous. Use Present Simple for permanent situations without time reference, Present Continuous only for explicitly temporary arrangements.
Mistake 7
❌ Incorrect: ❌ I go to the gym right now, so I'll call you later.
✓ Correct: ✓ I'm going to the gym right now, so I'll call you later.
💡 Why: DIAGNOSTIC: This error occurs when learners use Present Simple for actions happening at the moment of speaking. 'Right now', 'at the moment', 'currently' are strong signals for Present Continuous, not Present Simple. Present Simple with 'right now' sounds unnatural because Present Simple expresses habits or general truths, not current temporary actions in progress. PREVENTION: Learn time markers: 'right now', 'at the moment', 'currently', 'at present' = Present Continuous. 'Usually', 'always', 'every day', 'often' = Present Simple. Check your time expressions before choosing tense.
Mistake 8
❌ Incorrect: ❌ The meeting is starting at 3 PM tomorrow according to the schedule.
✓ Correct: ✓ The meeting starts at 3 PM tomorrow according to the schedule.
💡 Why: DIAGNOSTIC: While Present Continuous can express future arrangements, when referring to official schedules, timetables, or published programs, Present Simple is more appropriate and natural. 'According to the schedule' signals that this is fixed and official, not a personal arrangement. Present Continuous suggests someone's personal plan, while Present Simple indicates an established, unchangeable schedule. PREVENTION: Notice phrases like 'according to the schedule/timetable', 'the program says', 'officially'—these signal fixed schedules requiring Present Simple. Use Present Continuous for personal future plans, Present Simple for official schedules.
Mistake 9
❌ Incorrect: ❌ As soon as I will have time, I help you with your homework.
✓ Correct: ✓ As soon as I have time, I'll help you with your homework.
💡 Why: DIAGNOSTIC: This error combines two mistakes: using future tense after 'as soon as' (should be Present Simple) and using Present Simple in the main clause (should be future with will). Learners often confuse which clause needs which tense. The time clause (after as soon as, when, before, after, until) takes Present Simple; the main clause takes will/won't to show future result. PREVENTION: Learn the pattern: 'Time word + Present Simple, will + base verb.' The time clause (starting with when/as soon as/before/after/until) = Present Simple. The result clause = will. Check that you have one Present Simple and one future form.
Mistake 10
❌ Incorrect: ❌ If you are heating ice, it is melting and becomes water.
✓ Correct: ✓ If you heat ice, it melts and becomes water.
💡 Why: DIAGNOSTIC: This error occurs when learners incorrectly use continuous forms in zero conditional sentences expressing general truths. Zero conditional describes cause-effect relationships that are always true, using Present Simple in both clauses. Continuous forms incorrectly suggest temporary or ongoing processes rather than permanent physical laws. The structure 'if + present simple, present simple' is fixed for general truths. PREVENTION: For zero conditional (general truths, scientific facts, always-true cause-effect), use Present Simple in both clauses. Ask: 'Is this always true for everyone, or just a specific situation?' If always true, use only Present Simple.
Mistake 11
❌ Incorrect: ❌ I am preferring tea to coffee, and I am also liking green tea especially.
✓ Correct: ✓ I prefer tea to coffee, and I also like green tea especially.
💡 Why: DIAGNOSTIC: This error happens when learners treat preference and opinion verbs like action verbs. Prefer, like, love, hate, want, need are state verbs expressing feelings or preferences that exist as states, not actions in progress. They cannot take continuous forms in standard English. Even when expressing current feelings, use Present Simple. PREVENTION: Memorize state verbs of preference and feeling: like, love, hate, prefer, want, need, wish. These never use continuous forms. If expressing a current feeling or preference, still use Present Simple: 'I like it' not 'I'm liking it.'
Mistake 12
❌ Incorrect: ❌ The sun is rising in the east every day and setting in the west.
✓ Correct: ✓ The sun rises in the east every day and sets in the west.
💡 Why: DIAGNOSTIC: This error combines Present Continuous with 'every day', which is contradictory. Present Continuous describes temporary actions in progress, while 'every day' signals habitual, repeated actions requiring Present Simple. Additionally, this describes a permanent natural phenomenon, not a temporary process. The continuous forms incorrectly suggest this pattern might change. PREVENTION: When you see frequency expressions (every day/week/month, always, usually, often, sometimes, never), automatically use Present Simple, never continuous. Present Continuous cannot express habits or regular repetition.
Mistake 13
❌ Incorrect: ❌ She doesn't agrees with your opinion about the new policy.
✓ Correct: ✓ She doesn't agree with your opinion about the new policy.
💡 Why: DIAGNOSTIC: This error occurs because learners add -s to the main verb after doesn't/does, forgetting that the -s moves to the auxiliary. In negative and question forms with do/does, the auxiliary takes the -s marker, and the main verb returns to base form. This is a fundamental rule but frequently forgotten under pressure. PREVENTION: Remember: the -s can appear only once—either on does or on the main verb, never both. In negatives and questions with does, the main verb is always base form. Check every negative and question: 'Does she agree?' 'She doesn't agree' (never 'agrees').
Mistake 14
❌ Incorrect: ❌ I go to London next week for an important business meeting.
✓ Correct: ✓ I'm going to London next week for an important business meeting.
💡 Why: DIAGNOSTIC: While Present Simple can express scheduled future events, it's typically reserved for timetables and official schedules, not personal plans. For personal future arrangements, Present Continuous is more natural and appropriate. Using Present Simple for personal plans sounds unnatural and overly formal or strange to native speakers. PREVENTION: Use Present Simple for official schedules (trains, classes, cinema times). Use Present Continuous for personal future arrangements (trips you've planned, meetings you've arranged). Ask: 'Is this an official timetable or my personal plan?' Personal plans = Present Continuous.
Mistake 15
❌ Incorrect: ❌ Do your brother works in the same company as you?
✓ Correct: ✓ Does your brother work in the same company as you?
💡 Why: DIAGNOSTIC: This error shows confusion about subject-verb agreement in questions. Learners incorrectly use 'do' with third-person singular subjects, or add -s to the verb after the auxiliary. For he/she/it, use 'does' (not 'do'), and the main verb must be base form (not 'works'). The -s marker appears on the auxiliary 'does', never on both. PREVENTION: Check the subject: I/you/we/they = do + base verb. He/she/it = does + base verb. In questions and negatives, the -s is only on does/doesn't, never on the main verb. Practice: 'Does he work?' 'He doesn't work' (never 'works' after does/doesn't).
