💡 We use 'have seen' for a life experience. The rule is: have/has + past participle. 'Have saw' uses the wrong participle. 'Has seen' is for he/she/it. 'Saw' is past simple — wrong here because there is no finished time.

💡 We use 'has visited' because the subject is 'she' — third person singular needs 'has'. 'Have visited' is wrong for she/he/it. 'Has visit' is missing the past participle. 'Visited' is past simple.

💡 After 'have you ever', we need the past participle. 'Eaten' is the correct past participle of 'eat'. 'Ate' is past simple. 'Eating' is the -ing form. 'Eat' is the base form.

💡 We use 'been' for a place someone has visited and returned from. 'Gone' means they are still there. 'Went' is past simple. 'Be' is the base form — we need the past participle.

💡 After 'have never', we need the past participle. 'Tried' is the correct past participle of 'try'. 'Try' is the base form. 'Trying' is the -ing form. 'Have tried' repeats the auxiliary — that is wrong here.

💡 We use 'have watched' because the subject is 'they' — plural needs 'have'. 'Has watched' is for he/she/it. 'Have watch' is missing the past participle ending. 'Have watching' uses the wrong form.

💡 We use 'been' because Marco went and came back — it is a life experience. 'Gone' means he is still at the cinema now. 'Went' is past simple. 'Go' is the base form — not a past participle.

💡 We use 'never' with a positive verb to make a negative meaning. 'Haven't never' is a double negative — that is wrong in English. 'Not never' is also a double negative. 'Ever' is used in questions, not in negative statements like this.

💡 After 'has ever', we need the past participle. 'Met' is the correct past participle of 'meet'. 'Meet' is the base form. 'Meeting' is the -ing form. 'Meeted' is not a real word — 'meet' is an irregular verb.

💡 We use 'have ever seen' in the superlative pattern: the best + I + have ever + past participle. 'Have ever saw' uses the wrong participle. 'Ever have seen' has the wrong word order. 'Has ever seen' is for he/she/it, not I.

💡 We use 'has' because the subject is 'she' — third person singular. 'Have' is for I/you/we/they. 'Is' and 'was' are forms of 'be' — they do not make the present perfect.

💡 We use past simple 'went' to give details about when the experience happened. '2019 and 2022' are finished times. 'Have gone' and 'have been' are present perfect — wrong with finished time expressions. 'Have went' uses the wrong participle.

💡 We use 'Have' to make a present perfect question with 'you'. 'Has' is for he/she/it. 'Did' makes a past simple question — wrong for a life experience question. 'Are' makes a present continuous question.

💡 After 'have', we need the past participle. 'Read' is both the base form and the past participle of 'read'. 'Readed' is not correct — 'read' is an irregular verb. 'Reading' is the -ing form. 'Reads' is the third person present simple.

💡 We use 'Has' because the subject is 'your sister' — third person singular. 'Have' is for I/you/we/they. 'Did' makes a past simple question. 'Is' makes a present continuous question.

🇮🇹 In Italian, you use 'ha' for third person. In English, the rule is the same: 'has' for he/she/it.

💡 We use 'been' for a place you visited and came back from — or never visited. 'Gone' means you are still there now. 'Went' is past simple. 'Go' is the base form — not a past participle.

💡 We use past simple 'saw' because '2020' is a finished time. 'Has seen' is present perfect — wrong with a finished time like 2020. 'Has saw' uses the wrong participle. 'Have seen' does not match 'he'.

🇮🇹 In Italian, you can often use the passato prossimo with a time like '2020'. In English, a finished time like '2020' always needs the past simple.

💡 We use 'have' because the subject is 'I'. 'Has' is for he/she/it. 'Am' makes a present continuous form. 'Did' makes a past simple form — wrong here.

💡 After 'have you ever', we need the past participle. 'Watched' is the correct past participle of 'watch'. 'Watch' is the base form. 'Watching' is the -ing form. 'Watches' is the third person present simple.

💡 We use 'have' in the superlative pattern: the most extreme + I + have ever + past participle. 'Has' is for he/she/it. 'Had' on its own does not make the present perfect here. 'Am' is a form of 'be'.

💡 We use 'has' because the subject is 'she'. Here 'gone' is correct — she is still in New York now, not back home. 'Have' is for I/you/we/they. 'Is' and 'was' are forms of 'be'.

💡 We use past simple 'saw' because 'last week' is a finished time. You cannot use the present perfect with 'last week'. 'Have seen' and 'has seen' are present perfect — wrong with finished time expressions. 'Have saw' uses the wrong participle.

🇮🇹 In Italian, you might say 'ho visto' with 'la settimana scorsa'. In English, 'last week' always needs the past simple: 'I saw'.

💡 We use 'ever' after 'haven't' to talk about a life experience you have not had. 'Never' with 'haven't' makes a double negative — that is wrong in English. 'Not' is already in 'haven't'. 'Already' does not fit this meaning.

💡 We use 'have' because the subject is 'my parents' — plural. 'Has' is for he/she/it. 'Did' makes a past simple form. 'Are' makes a present continuous form.

💡 We use 'been' because it is a life experience — I visited Paris and came back. 'Gone' means I am still in Paris now. 'Went' is past simple — wrong after 'have'. 'Go' is the base form — not a past participle.

💡 We use 'Have' to make a present perfect question with 'you'. 'Has' is for he/she/it. 'Did' makes a past simple question — wrong for a life experience question with 'ever'. 'Do' makes a present simple question.
