我还没收到他的来信的英语 I haven't heard from him yet 这里为什么是heard from而不 i haven't heard from him recently. I haven't heard from him last week. I haven't heard from him( )he went abroad 语法题:I haven't heard from him ( ). He said"I haven't heard from him since May". we haven't heard from them since last month.为什么这里不能用until啊? I haven’t heard from Maria_____. 翻译the scientists haven't heard from it yet i haven't heard from my parents（ ）填yet还是just 3.-Have you heard from him yet?A.I don't mind B.Yes,I have I haven't heard from him since last week .请问这句话对吗?
