(1) Is this hotel ___ you said we were to stay in your letter?(2) Is this the hotel _(急~)
(1) Is this hotel _____ you said we were to stay in your letter?
(2) Is this the hotel _____ you said we were to stay in your letter?
A.that B.where C.the one D.in which
我知道第一题选B第二题选D.
第一题是where引导的表语从句,那where应该翻译"哪里".那么整句话的翻译是什么?stay in 中的 in是 后面的in your letter 还是stay in 构成一个短语词组翻译"呆在家里;不外出"?
第二题是定语从句,不懂怎么该理解这题!如果选in which的话,那where不是也可以啊?
求外国佬,英语语法教授来帮帮忙啊!
