文法分析 - Object pronouns - 8
抽選練習: Rewrite the sentences by replacing the underlined nouns and expressions with one or two pronouns.
- Je n'ai jamais rencontré tes amies.
(= I've never met your friends.)
正確答案：Je ne les ai jamais rencontrées.
錯誤示範：Je ne les ^ jamais rencontré.
分析要點：
- lack of auxiliary verb (avoir)
- past participle agreement with the direct object pronoun (les) for verb with auxiliary verb (avoir)
概念分析：For verbs with auxiliary verb (avoir) in the passé composé, past participle agreement in number and gender has to be made with the preceding direct object pronoun la (l'), les, nous and vous.
les: tes amies (f. pl.)
Je ne les ai jamais rencontrées.
Reminder on past participle agreement
Things may be a little bit more sophisticated when there is also an infinitive in a sentence with passé composé.
e.g. Nous avons vu la navette spatiale traverser le ciel.
(= We saw the space shuttle crossing the sky.)
It the direct object doubles as a subject of the infinitive, agreement of the past pasticiple must be made.
l': la navette spatiale (f.)
the direct object pronoun la becomes l' in front of a vowel.
= Nous l'avons vue traverser le ciel.
BUT:
If the direct object does not double as the subject of the infinitive, no agreement would be required for the past participle.
e.g. Nous avons vu démolir la vieille prison.
(= We saw the old prison being demolished.)
In this case, 'la vieille prison' is the object for the infinitive 'démolir', not subject.
Nous l'avons vu(_) démolir. (nothing is added at the end of the past participle)
