問題1, 有關present participle:
我知道relative clause 有relative pronoun + be +pp,就可變成reduced relative clause
e.g : There are two students who are waiting outside.
變成 There are two students waiting outside.
但跟住呢句就唔明:
My parent, who didn't have much money, never went on holiday.
變成 My parent, not having much money, never went on holiday.
點解原句無be 又無pp都可變有pp 的 reduced relative clause ?

問題2, 有關prefect passive:
例句1: The strawberries which had been dipped in chocolate were really delicious.
變成 The strawberries dipped in chocolate were really delicious.
(omit左 which had been)
例句2: We are concerned about people who have been held in prison for years.
變成 We are concerned about people having been held in prison for years.
(who have 變左 having)
點解有兩種變法?
