📚 Guessing Games: How to Talk About Possibilities in English A2
🎯 8 grammar forms💬 27 examples⏱️ 3-4 minutes
📖 Story Summary
When you're not sure about something, English has special words to help you guess. Your friend isn't answering her phone – where is she? You can say 'She may be at work' or 'She might be sleeping.' These are modal verbs for speculation. But be careful! 'Maybe' (one word) and 'may be' (two words) sound the same but work differently. 'Maybe' starts a sentence like an adverb: 'Maybe she's at home.' But 'may be' comes after the subject: 'She may be at home.' For the past, the structure changes. If your friend didn't come to the party yesterday, you can guess: 'She may have been sick' or 'She might have been working.' These small words help you sound natural when you don't know something for certain.

Test your understanding of the grammar forms from the story.
may be
Which sentence uses 'may be' correctly to guess about a present situation?
'May be' (two words) is a modal verb that comes after the subject to express uncertainty about present situations. 'Maybe' (one word) is different – it's an adverb that starts sentences.
may be
In the sentence 'He may be tired,' what does 'may be' express?
'May be' expresses speculation or uncertainty about present situations. The speaker is not certain – they are making a guess about his current state.
might be
Which sentence correctly uses 'might be' with a continuous form to guess about a present activity?
The correct structure is 'might be + verb-ing' to speculate about an action in progress. 'Might' is followed by the base form 'be', then the -ing form of the main verb.
might be
Which sentence contains an error?
'Might are' is incorrect. Modal verbs like 'might' are always followed by the base form of the verb ('be'), never by conjugated forms like 'are' or 'is'.
could be
Which sentence uses 'could be' correctly for present speculation?
'Could be' is the correct form for guessing about present situations. The modal 'could' is followed by the base form 'be', not conjugated forms or past participles.
could be
In the sentence 'The weather could be changing,' what does 'could be changing' express?
'Could be changing' expresses speculation about a present action in progress. The speaker is not certain but is guessing that the weather is currently changing.
maybe vs may be
Which sentence correctly uses 'maybe' (one word) as an adverb?
'Maybe' (one word) is an adverb that typically starts a sentence. 'May be' (two words) is a modal verb that comes after the subject. Both express uncertainty but have different positions.
maybe vs may be
Which sentence contains an error in using maybe/may be?
'She maybe at home' is incorrect. After the subject, you need 'may be' (two words) as a modal verb. 'Maybe' (one word) should start the sentence: 'Maybe she's at home.'
may have been
Which sentence correctly uses 'may have been' to guess about a past situation?
The correct structure for past speculation is 'may have been'. The modal 'may' is followed by 'have' (not 'has') and then 'been'.
may have been
In the sentence 'He may have been working,' what does 'may have been working' express?
'May have been working' expresses speculation about a past continuous action. The speaker is guessing about what he was doing at a specific time in the past.
might have been
Which sentence uses 'might have been' correctly for past speculation?
The correct structure is 'might have been' for guessing about past situations. After 'might', we use 'have' (not 'has') followed by 'been'.
might have been
Which sentence contains an error?
'They might have sleeping' is missing 'been'. The correct structure for past continuous speculation is 'might have been + verb-ing'.
must be vs may be
What is the difference between 'She must be at home' and 'She may be at home'?
'Must be' expresses a strong deduction (the speaker is almost certain based on evidence), while 'may be' expresses speculation or uncertainty (the speaker is just guessing).
continuous with modals
Which sentence correctly uses a modal with continuous form to guess about an action in progress?
The correct structure is 'modal + be + verb-ing'. After the modal 'could', we use 'be' followed by the -ing form: 'could be driving'.
continuous with modals
Complete the sentence: 'They ____ eating dinner right now.'
To speculate about an action in progress, we use 'may be' (two words) followed by the -ing form: 'may be eating'. 'Maybe' (one word) is an adverb and can't be followed directly by a verb-ing form.
