优质解答

1.---Do you mind if I open the window?
---_______ I feel a bit cold.
A:Of course not.B:I'd rather you didn't.C:Go ahead D:Why not?
(此题正确选项为B,为什么用didn't,不用don't呢?）
would rather sb did sth.宁愿某人干某事
这个句型要求would rather 后面的从句用一般过去时表示虚拟语气,表达现在或者将来的愿望.
又如：I would rather you came tomorrow than today.
2.China,which has the largest population of the world,joined the WTO in 2001,____15 years of talks.
A:to end B:ended C:ending D:ends
(正确答案选C,ending 15 years of talks做什么成分呢)
现在分词短语做结果状语,表示顺其自然的结果.
拥有世界上人口最多的中国于2001年加入WTO,从而结束了15年的会谈.
3.--Do you regret not having gone abroad?
--Not at all.I ________ as much.but I'm glad to contribute to our motherland.
A:didn't earn B:am not earning C:hadn't earned D:haven't earned
(为什么选B)
第二句话的意思是：
一点也不后悔.我现在挣的钱没有像出国挣得那么多,但是我很高兴能为祖国效劳.
用现在进行时表示现在的状况,所以先排除两个过去时态的A和B.
D 现在完成时强调动作对现在的影响.用在这里不合适.
4.--Brad was Jane's brother!
___ he reminded me so much of Jane!( 此句怎么翻译）
A:No doubt B:Above all C:No wonder D:Of course
选C.难怪他让我那么想起Jane来.（言外之意是兄妹两个人长得很像,看到这个就不禁想到了另一个.）
5.As far as I know,she is seldom,______ .absent from school.
A:if ever B:if much C:if not D:if any (为什么选A,怎么翻译）
if ever 如果曾经有的话.if not如果不 if any 如果有的话（强调数量）
如：Correct the mistake if any.
if much没有这种用法.
6.The three nations were wise enough not ______ the agreement until they could discuss it further.
A:to sign B:signing C:having signed D:to have signed (为什么选D）
enough 后常接不定式,所以排除B 和C.
选D 不定式的完成时表示已经签署协议.
7.________ Zhai Zhigang began his historic step in outer space,all we Chinese felt excited and proud!
A:When the first time B:At first C:The first time D:For the first time (为什么选C不选D）
The first time是连词,引导状语从句.
For the first time是介词短语在句中做时间状语,不可以引导从句.
如：I have been here for the first time.
8.He was busy writing a story,only _____ once in a while to smoke a cigarette.
A:to stop B:stopping C:to have stopped D:having stopped (为什么选B）
stopping once in a while to smoke a cigarette.是现在分词做伴随状语,
A to stop是不定式作状语,和only搭配表示出乎意料的结果.
D having stopped 表示在谓语动词was writing之前完成的动作.
9.______ unemployment and crime are high,it can be assumed that the latter is due to the former.
A:Before B:Where C:Unless D:Until (正确答案选B,这是个定语从句吗,先行词是什么）
是地点状语从句,定语从句一般不可以放在句首,要放在先行词后面.
又如：Where there is a will,there is a way.
10.With more forests being destroyed,huge quantities of good earth _____ each year.
A:is washing away B:is being washed away C:are washing away D:are being washed away (为什么选D不选B)
huge/large quantities of 修饰名词作主语时,谓语动词都用复数,要和quantities一致.
a large quantity of 修饰不可数名词时,谓语动词用单数,和quantity一致.
