问题描述：
He differed from his workmates _ he devoted his spare time to charity.为什么填 in that
介词后面不是接which
答
in that 这里in后面跟的是宾语从句,是介宾.
不能用which,which引导定语从句,在从句中要做宾语,主语,或表语.而从句结构完整,所以选择in that ,其中that 在宾语从句中不做成分.也就是说in 表示他与其他人在哪些方面不同，是吗？He differed from his workmates in sth,that也可以省略掉吧Animals suffered at the hands of man ---they were destroyed by people to......中间也填in that 是同样道理吗对。呵呵，再求教一个，谢谢……by the time you arrive home ,I --,so please don't make any noisewhen you come in这句为什么要用shall be sleeping,不用shall have been sleeping.不是有by the time 吗，应该有完成时by +将来时间，谓语用一般将来时态。by +now现在完成时态by +过去时间过去完成时态
