【答案】

C

【解析】

试题分析:句意:如果我有一百万美元,我应该怎么做?——如果我是你,我会把它捐给医学研究。If条件句中表示与现状相反的事实,用过去时态。be通常用were,故选C。

考点:if引导的条件状语从句

点评:虚拟语气是一种特殊的动词形式,用来表示说话人所说的话并不是事实,而是一种假设、愿望、怀疑或推测。其主要有三种结构:

1、与现在事实相反

若与现在事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”

2、与过去事实相反

若与过去事实相反,条件从句的谓语用过去完成时(had+过去分词),主句谓语用“should (would, could, might)+have+过去分词”

3、与将来事实相反

若与将来事实相反,条件从句的谓语用过去式(be通常用were),主句谓语用“should (would, could, might)+动词原形”:

Try reading the following sentences as fast as you can. “She sells seashells by the seashore. The shells she sells are surely seashells. So if she sells shells on the seashore, I’m sure she sells seashore shells.”

Not very easy, was it? What you’ve just read is called a tongue twister (绕口令). It is an exercise made up of sounds that are hard to pronounce(发音,读) in order to help people pronounce words faster and more correctly. Try the next example.

“Peter Piper picked a peck of pickled pepper. Did Peter Piper pick a peck of pickled peppers? If Pete Piper picked a peck of pickled peppers, where’s the peck of pickled peppers Peter Piper picked?”

Tongue twisters usually do not have much meaning. They are just designed to improve people’s ability  to pronounce words. Although they may be very difficult, these exercises are very important to people who are trying to speak English correctly. This is because tongue twisters help people to tell the differences between similar sounds.

So if you wish to pronounce words more smoothly, you’d better try picking out some tongue twisters and practicing them.
