Fill in have or has. 1. ................. he ever travelled by plane? – No, he n't.

Fill in have or has.

Explanation: This exercise focuses on the present perfect tense, which uses 'have' or 'has' as auxiliary verbs. 'Has' is used with third-person singular subjects (he, she, it), and 'have' is used with all other subjects (I, you, we, they).

• 1. Has he ever travelled by plane? – No, he hasn't. (The subject is 'he', so 'has' is used for the question and 'hasn't' for the negative answer).
