I may habe been at Christmas__John gave Mary a gandbag.A.he B.it C.that D.because
什么.为什么?这是强调句吗?如果不是,那又是什么句式呢?

【选择】D. when

【解析】

　　句意分析：
　　may have been at Christmas 是虚拟语气,表示对过去的一种不敢断言的推测,后面需要指出所推测的这件事的发生时间.填入when 正好是表示这件事发生在过去的时间状语,意思是“约翰给玛丽手提包的时候,我（当时）大概是在圣诞节那天度假”.

　　其他选项：
　　填写 before 也可以作时间状语,不过“给手提包”是发生在圣诞节以后的事,“大概是在”表示过去,“给手提包”则是过去以前的是,意思是“约翰给玛丽手提包的之前,我大概在圣诞节那天度假”,因此原句应该用过去完成时 had given 才成立.
　　who 和 that 都不能用来引导状语从句.

　　强调不能少了强调代词 it,其结构是 ——
强调人：It is + 被强调的人 + that（或who）+ 其余部分
强调其他成分：It is + 被强调的成分 + that + 其余部分
再问：如果是如下这个句子，它是强调句型吗？
It may have been at Chritmas___John gave Mary a handbag.
再答：符合强调句型结构，因此它是强调句。句中强调时间状语 at Chritmas，要用连词 that，意思是“很可能就在圣诞节的时候约翰给了玛丽一个手提包”。如果不强调应该是 John gave Mary a handbag at Chritmas，意思是“约翰在圣诞节给了玛丽一个手提包”。
