单项填空

①—Shall we go skating or stay at home?

—Which

do yourself?

（2010·01·江西南昌检测）

A. do you rather

B. would you rather

C. will you rather

D. should you rather

②I’d rather

the basketball match last night. Otherwise, I would have finished my paperwork by now.

（2010·01·江苏徐州检测）

A. not have watched

B. not watch C. hadn’t watch

D. haven’t watch

①解析：选B。考查would rather do sth.这一结构的用法。而do, will和should都不能与rather 搭配。would rather (not) do sth.意为“宁愿（不愿意）做某事”。

②解析：选A。would rather not have done意为“本不想做……（实际却做了）”。后一句句意为：否则我现在已经完成了我的文件。

所以前句表示“本不想看球赛却看了”，故选A。

11. therefore adv. 因此；所以；因而

eg: There’s still much to discuss. We shall, therefore, return to this plan at our next meeting. 要讨论的问题还有很多。所以，我们将在下次会议中再讨论这个计划。

不定式放在表示次序的词the first, the last, the best以及the only, the very, the right等词后面, 且这些词与动词不定式有逻辑上的主谓关系，结构为：the first/last/best/only/very/right ...+n. + to do sth. 表示“第一个/最后一个/最好的一个/唯一的/恰好的/合适的……做某事的人/物”。

单项填空

He is the last person

to Mary’s birthday party.（原创）

A. to invite

B. to be invited

C. invited

D.

解析：选B。考查不定式作定语的用法。当名词前面有序数词或last, next等词修饰时，名词后面多用不定式作定语。如New Zealand was the first nation in modern times to allow women to vote. 新西兰成为现代史上第一个允许妇女有选举权的国家。
