Is this the man that you served?句中能不能把that 换做who或whom?能否省略关联 Is this the man that you served?这句话中that可以用who代替吗? Is this the man that you served 为什么用that 英语翻译1.who served you?The man who/that is standing behind the 定语从句 This is the man I met yesterday中省略的是who还是whom Where is the man that/whom I saw this morning?请问这句为什么用whom 改错this is the man whom served you half an hour ago Who is the man __you just talk with (who whom that all the a he is the man (whom/that/who) you just talked to为什么那三个可以用,还可 15.Who’s the man you just talked with?A.who B.whom C.that D. who is the man _ made mistakes?A who B that C whom D whose 为 He is the man (who/whom/that) I met.为什么这里用who和whom都可以
