Need / want / require/ deserve + doing

某物需要被怎么样,表示被动,如 the bike needs repairing这辆车需要修了。等于Need / want / require/ deserve + to be done
再问： 那加to do 是什么意思？ need+to do 也是需要怎么样啊 那是不是主动啊？
再答： The bike needs to be repaired。 被动指的是to do 中的do是 be done。 need to do 还是主动。就是这样：I need to do this homework。我要做作业。 The car needs to be repaired=the car needs repairing这辆车要修。被动是指 to be done,动词不定时的被动，就和过去式被动 was done，进行时被动 is being done一个性质。你问的need repairing 是不定时被动的特殊用法
再问： 哦 谢谢啊~
