Could it be in the room _________ we had a talk last night _
4个回答

已收到你的求助,答案选【C】

这里考察两个语法点

【1】定语从句

【2】It's ···that···的强调句

首先 将疑问句改为陈述句来看

It could be in the room where we had a talk last night that you left your keys.

然后划分出强调句型

【It could be】 in the room where we had a talk last night 【that】 you left your keys.

再然后分析定语从句

the room where we had a talk last night

这里从句完整,we【主语】 had 【谓语】a talk【宾语】 last night【时间状语】

缺少【地点状语】,故采用where或者in which都是可以的,两者等价(关系副词=关系代词+介词)

希望帮助到了你!
