本题检测考生在实际情景中运用英语进行交际的能力。A、B、C三个选项考生比较熟悉,但是对How come这种说法并不熟悉,下面对How come在交际用语中以及其它一些用法进行归纳:

I. How come...?

How come是固定搭配,意为:怎么会......?怎么回事......?怎么搞的......?它和Why一样,可以用来引导一个问句。所不同的是,如果用How come来提问,就表示你觉得某件事很奇怪,有点想不通;并且,以How come开头的问句使用的仍是陈述句的语序。如:

How come you didn't tell me earlier ? (=Why didn't you tell me earlier ?) 你怎么不早点儿告诉我?

How come you didn't invite him to the party! He is your future boss. 你怎么没有邀请他参加晚会!他是你未来的老板。

另外,以How come开头的问句有时也可说成:How comes it (about) that... ? / How is it that... ? 如:

How comes it that you're so late? (=How is it that you're so late?) 你为什么来得这么迟?

II. What for?

What for... ? 是询问什么原因或目的,相当于:Why...? / For what purpose...? 如:

What do you need to borrow money for? I thought you had plenty of money. 你为什么需要借钱? 我本以为你有许多钱。

-Let's go and have a good drink tonight.

-________ Have you got the first prize in

the competition?

B. Thanks a lot.

答案: A

1. 用来询问情况或打听消息等,意为:......怎么样?......如何?如:

How about your English exam yesterday? 你昨天的英语考得怎么样?

-How are you getting on with your work? 你工作情况如何?

-Not bad. What about you? 不错,你呢?

2. 用来提出请求、建议或征求对方意见,后面除跟sth. 外,还可跟动名词doing,意为:你认为......怎么样?......如何?如:

How about the two of us ________ a walk down the garden?

A. to take

B. take

C. taking

D. to be taking 答案: C

IV. Why not ?

Why not...? 用来向对方提出一个建议,意思是"何不......?" 它是一个省略形式的问句,相当于Why don't you / we...? 如:

Why not go home now? = Why don't you go home now? 你为什么现在不回家呢?

Why not go out for a walk? = Why don't we go out for a walk? 我们何不出去散散步呢? 注意:Why not后面必须接动词原形,即Why not do...? 如:

-I usually go there by train.

-Why not ________ by boat for a change? A. to try going B. trying to go

C. to try and go

D. try going

答案: D

V. If only...

If only意思是"但愿......;要是......就好了",常引导虚拟语气的条件句或感叹句,用来表示说话人对某事所寄予的某种强烈愿望,相当

于as long as。如:

If only I were as clever as you!要是我像你一样聪明该多好啊!

If only we had arrived in time, we would not have missed the train. 要是我们按时到,就不会误车了。

If only it would stop raining! 但愿雨停下来。

注意: only if 也引导条件状语从句,表示"只有......(才);只有在......的时候;唯一的条件是......"的意思;与if引起的条件句相比,语气更强。如:

He will succeed only if he does his best. 他只有尽力而为才能成功。

I'll come only if you really need me. 只有当你真正需要我的时候,我才来。

VI. What if?
