分析要點：direct object pronoun (le/l') versus adverbial pronoun (en)
概念分析：
- identify what preposition is used (à/de?): de
- identify what kind of clause is used following the preposition (infinitive/conjugated?): infinitive clause
pattern: de + infinitive clause
= de + sortir un soir de semaine
- the use of direct object pronoun (le) and adverbial pronoun (en) depends upon if the preposition de is a part of the expression or not.
e.g. avoir envie de: will be considered as a whole
VERSUS: permettre + de: will be considered as two separate things - verb with the preposition de
Adverbial pronoun (en) is used when de belongs to the expression as a whole while direct object pronoun (le/l') is used when de simply follows the verb. Even for verbs with the preposition de, the verb itself and de would be seen as two separate things in this context.
Thus, the direct object pronoun (le) must be used to replace de + infinitive clause instead of adverbial pronoun (en) in this case.
l': de + sortir un soir de semaine
Ils ne nous l'ont pas permis.
