TEM4---英语专业四级语法词汇+答案详解03-132013年51. Facing the board of directors, he didn’t deny ________ breaking the agreement.A. himB. itC. hisD. its解析:动名词可以有自己的逻辑主语,一般可以用名词所有格Tom's,代词宾格如him(口语),书面语情况下一般用物主代词his,their。
本题选C。
52. Xinchun returned from abroad a different man. The italicized part functions as a (n) _______.A. appositive (同位语)B. objectC. adverbialD. complement.解析:这些一般语法书也会提到,但是题目里的都不是这种现象,很多语法书对主语补语的介绍也就到此为止。
好在这本书多介绍了一点,但情况很微妙。
此书又说More problematic is the constituent following other verbs that could be used intransitively with the same meaning, as in: Saint Ethelbert was born a Saxon princess. (she was born) He returned a broken man. (he returned) He died young. (he died) We shall consider such constituents as Complements on the strength of the possible paraphrase containing be (When he returned he was a broken man; When he died he was young). 这部分恰好就是本题所代表的类型,但是从该书作者表述来看,他们也承认这样的句子很不一般,不太容易轻易判定是否为主语补语,在本书里,作者认为可以看作是主语补语,因为大概可以改写成含有系动词be的句子,但作者的措辞显然没有那么肯定,有待商榷的意思。

专四选择题高频词汇一、词汇题1。
1. 题目:The new secretary has written a remarkably ______ report only in a few pages but with all the details.A. conciseB. clearC. preciseD. elaborate.2. 答案:A。
3. 解析:- concise表示“简洁的,简明扼要的”。
句子中说报告只有几页但包含所有细节,这表明报告很简洁,所以选A。
- clear主要强调清晰、易懂,没有强调简洁这一特性,如“a clear explanation”(清晰的解释)。
- precise侧重于精确、准确,例如“precise measurement”(精确的测量),与句子中表达的简洁含义不符。
- elaborate表示“详尽的,精心制作的”,与“only in a few pages”矛盾。
二、词汇题2。
1. 题目:The two - year - old boy has a(n) ______ for music. He can play several instruments well.A. talentB. geniusC. giftD. ability.2. 答案:C。
3. 解析:- have a gift for是固定搭配,表示“对……有天赋”。
- talent虽然也表示天赋,但通常搭配是“have talent in/for”,这里用法不太符合。
- genius强调天才的程度更高,一般说“be a genius”(是个天才),而不是“have a genius for”这种用法。
- ability表示能力,侧重于做某事的能力,没有“gift”那种天生的、特殊的天赋的意味。
三、词汇题3。

试题答案与解析(一)1. C) 【句意】虽然只懂一点西班牙语,但他还是参加了这个课程的学习。
【难点】know是静态动词,不能用于进行时;选knows从句中又缺少主语。
knowledge作“知识”讲时是不可数名词,但作“了解”讲时,前面可加“a”,常用于词组have a knowledge of中,所以选C)。
2. B) 【句意】你本应该给詹姆斯写信,然而,你没写。
【难点】ought to have written是虚拟语气,与本句句意相符。
3. B) 【句意】约瑟夫幸运地逃了性命;他险些没从房间里逃出来。
【难点】to have escaped 是不定式的完成式,表示过去的某一动作业已完成。
4. A) 【句意】黄油面包受西方人青睐。
【难点】bread and butter 是西方人吃的一种食品,虽然有三个字,表达的却是一个东西,并且是不可数名词,作单数。
5. A) 【句意】我家的后花园有一片草坪,夏天坐在上面会令你心旷神怡。
【难点】which引出非限制性定语从句,在句中作主语,且和sit on 构成动宾关系。
类似的句子有:This room is comfortable to live in 这句中live in 和this room构成动宾关系。
6. C) 【句意】他独自一人开始经商,并且做得很成功。
【难点】on one’s own 是个常用的介词词组,意为“独自”;of one’s own 表示“某人自己的(东西)”,如:I have a flat of my own.我自己有套房子。
7. C) 【句意】约翰的考试分数全班最高;他昨天晚上一定学习了。
【难点】表示对过去某一动作行为的猜测须要用must have done这一句型结构。
8. B) 【句意】弗兰克几乎从未受过任何教育,是不是?【难点】这是一句含有否定副词never的一般过去时的句子,由于主句为否定形式,所以反意问句用肯定形式。
9. C) 【句意】即使他的信明天到也无济于事了。
专四词汇练习及答案解析(3)
在现代英语中,have to 中不定式和疑问句式既可以按照助动词的变化规则构成,也可以按照行为动词的变化规则构成。
Have you to finish the work before supper?
Do you have to finish the work before supper?
have got to 常可同have to换用,但有时表示不同的含义。
比较:
He has to report to the headquarters every two days.(例行公事,习惯动作)
He has got to report to the headquarters every two days.(一道指示或命令,必得每天报告一次)
另外,作“有”解时,have got和have通常是可以换用的,have got更口语化,但有时表示不同的含义。
比较:
The man has a blind eye.那人有一只眼瞎了。
The man has got a blue eye.那人有一只眼被打青了。
must not表示禁止,是说话人强有力的劝告或命令,意为“一定要,不准”。
因此,在回答由must引导的问题时,如果是否定的回答,表示“不必,没有必要”,不能用mustn't,而要用needn't或don't have to.试比较:
You must not drive fast.你不能开快车。
(路险或有速度限制)
You needn't drive fast.(时间充裕)
You must not tell others.(警告)
You needn't tell others.(没有必要)
needs为副词,相当于necessarily, of necessity. must needs和needs must均可表示“必须,必定,不得不”,这层意义上可以通用;但must needs还可表示“偏偏,偏要”,含有讥讽、不满的意思,而needs must则一般无这层意思。
例如:
I must needs go there now.
我现在非到那里去不可。
(可用needs must)
Needs must when the devil drives.
情势所迫不得不那样。
She must needs go away when I want her.
我正需要她时,她偏偏离开了。
(不可用needs must)
The telephone must needs ring when I went to bed.
我上床睡觉时偏偏有人来电话。
(不可用needs must)
need指主语的主观特需情况而使之必要。
need既可以作助动词,又可以作行为动词。
作助动词时,need没有人称和数的变化,后接不带to的不定式(动词原形),否定式为needn't.作行动动词时,need同别的行为动词一样,有人称和数的变化,后接带to的不定式,否定式要在前面加don't (doesn't, didn't),疑问句用do (does, did)提问。
例如:
There need be no hurry, need there?
He need never know.(=He never needs to know.)
I need only add a few words.(= I only need to add a few words.)
比较:
Father sent me the book, so I didn't need to write to him for it.
父亲把那本书寄来了,所以我不必为此给他写信了。
(信没写)
Father sent me the book, so I needn't have written to him for it.
父亲把那本书寄来了,所以我本不该为此再写信给他的。
(信已写)
She didn't need to come.她不必来的。
(实际也没来)
She needn't have come.她本来不必来的。
(但却来了)
Note:
作助动词用时,need只用于疑问句中和否定句中,在肯定句中常用must,have to, should, ought to等。
例如:
Need you do it right now? I needn't, but he must.
She doesn't need to be told. She has already known it.
(客观情况使得告诉她没有必要:她已经知道)
She needn't be told. We should keep it secret from her.
(主观上不愿告诉)

1. You__ Jim anything about it. It was none of his business.
