抽選練習：Rewrite the sentences by replacing the underlined clauses with one or two pronouns. Be sure to identify the correct construction of the verb.- Il oublie toujours de fermer la porte à clé en partant.
(= He always forgets to close the door by key when he leaves.)
正確答案：Il l'oublie toujours.
OR: Il oublie toujours de faire ça.
錯誤示範：Il en oublie toujours.
分析要點：
- direct object pronoun (le/l') versus adverbial pronoun (en)
2. use of neutral stress pronoun (ça)
- verb with preposition de + infinitive
概念分析：
- identify which preposition is used (à/de?): de
- identify what kind of clause is used following the preposition (infinitive/conjugated?): infinitive
de + infinitive clause
de + fermer la porte à clé en partant
- since de follows the verb oublier, it suggests that they are two separate things and de is not a part of the expression. Direct object pronoun (l') must be used instead of adverbial pronoun (en) in this case.
l': de + fermer la porte à clé en partant
Il l'oublie toujours.
In the alternative, the preposition de is retained, followed by the verb 'faire' and neutral pronoun ça. Direct object pronoun (le/l') and adverbial pronoun (en) are not used in this case.
- use of neutral stress pronoun (ça)
Ça can be used to replace a human object, a noun or an infinitive clause. In this case, ça replaces the infinitive clause.
ça = fermer la porte à clé en partant.
- Certain verbs are followed by preposition de + infinitive.
oublier de + infinitive = to forget to
oublier de + faire + ça = to forget to do this
Thus, the full sentence would be as the following:
Il oublie toujours de faire ça.
