【key and explanation】

1,答案D。全句意思是:我希望所有预防空气污染的措施,如同当地政府所建议的那样,在这里都将被认真加以考虑。该句中的连词as与过去分词suggested连用,表示“正如...一样”。 2.答案B。全句意思是:选谁作为他的继承人这个问题经被很快解决了。“疑问词牛不定式”结构在句中作介词of的宾语,而空缺部分应该作select的逻辑宾语,因此只有whom符合句子要表达的意思。

3,答案D。全句意思是:尽管你的意见值得考虑,但委员会认为过分重视它是不明智的。while在这里是一个连词,表转折关系,意为“然而,虽然,尽管”。又如:While respected,he is not liked.管他受人尊敬,但并不被人喜爱。as和since表示原因,provided意为“假使”,用在本题中语意都不通。

4.答案Do全句意思是:这是设立大学的理想场所,因为这儿远离闹市。这里的in that引导原因状语从句,意为“由于,因为”。Provided that常引导条件状语从句,意为“如果”,nowthat意为“既然、由于”,sothat常引导结果或目的状语从句,意为“以致于”或“以便”。 5.答案C。全句意思是:你将需要两棵相距10英尺的树来挂你的帐篷。该句中which为关系代词引导定语从句,代替two trees。由于前面有介词,所以用which作介词的宾语,其他选项均不合题意。

6,答案B。全句意思是:在英国大多数作母亲的人直到最近才外出从事有偿劳动。该句中not...until结构为考点。until放在副词recently前,引导的状语部分前置,和否定的主句呼应,构成not ...until的搭配,表示“直到...才”。

7.答案D。全句意思是:尽管我承认有困难,但我认为它们不是不能解决的。while这里不表示动作在同一时间进行,而是一个连词,表示语气的转折,可译为“尽管,然而,但是”。根据该句的含义,其他三项均可排除。 8.答案B。全句意思是:约翰看起来像个很好的人。即使如此,我并不信任他。根据上下文的含义,空缺中应填人表达转折意思的副词。B项Even so相当于副词nevertheless,意为“即使如此,然而”。而even though意为“纵然”,是引导让步状语从句的连接词,不是副词。though虽然可用作表示转折意思的副词,但它通 常置于句尾或插于句子中间。therefore虽是副词,但意为“因此”,因而不能用于本题。

9.答案A。全句意思是:昨夜有人从监狱逃走,很长时间后警卫人员才发现。该句中before表示“在...以前”,但在翻译时为了更清楚地表达句子含义,通常译为“在...之后才发生”。又如:New ideas sometimes have to wait for years before they are fully accepted.有时候,新思想要等待多年以后才为人们完全接受。until是“直到...”的意思,since是“自从...以来”的意思,when通常表示“在...时”,三个选项在本题均不妥。

10.答案C。全句意思是:我们一到山顶,大家都坐下来休息。该句中的no sooner...than是一个复合连词,表示“一...就...”,类似的结构还有scarcely...when,hardly...when等。但要注意no sooner或scarcely,hardly放在句首时,要用倒装语序。又如:No sooner was he back home than he realized his mistake.他一回到家就意识到了自己的错误。

11.答案B。全句意思是:我们学完了这门课程,所以我们可以开始在复习上花更多时间。从全句的意思来看,应填人一个表示因果关系的连接词。now that是一个复合连接词,表示“既然”,有时也可省略that。For now表示“目前、眼下”,By now表示“至今”,都只能作状语,不能起连接词的作用。ever since可以起连接词的作用,但表示“从...以来”,与全句意思不合。

12.答案B。全句意思是:全世界都知道,马克·吐温是一位伟大的美国作家。从句子的结构可知前后是两个分句,因此空缺处应填人一个连接成分。as作关系代词,位于句首代替整个主句。 as在从句中作谓语动词is known的主语。if不是连接手段,如果句首用it,全句可改为:It is known to the world that Mark Twain is a great American writer.Which可用来代替整个主句,但必须位于主句之后。

13.答案C。全句意思是:正如土壤是地球的一部分,大气也是地球的一部分。“(just)as+从句,so+主句”结构是英语中常见的比喻结构。 as作为连词,意为“正如”,连接一个带有比喻意义的状语从句,so连接的是主句,其主谓语要倒装。这种结构可译为“正如...也可以”,“正如...,如是也”。A、B两项可先排除。D项虽然主谓倒装,但其前多了and,如果要保留and,前半部分必须是完整的简单句,不能是从句。 14.答案Co本题前半部分说“他们决定赶走这头牛”,后半句说“这头牛造成更多损失”。空缺处应填人一个连接词。从上下文看,全句意思是:他们决定在这头牛造成更多损失之前把它赶走。before表示“在...之前”。具体用法见第9题解析。

15.答案D。全句意思是:英国报界的与众不同之处在于它将报纸分成非常不同的两大类:讲究质量的报纸和大众化的报纸。in that常引导原因状语从句,表示“因为\由于”。

16.答案D。全句意思是:我们同意接受他们认为是最好的导游。该句后半部分是whoever引导的宾语从句。在

- 3 -

宾语从句中,they thought为插入语,whoever作为宾语从句的主语,因此不能用whomever。

17.答案D。全句意思是:那位在流通台前的年长的图书管理员答应,要是她记得谁最后借了那本书,她就会把它借给我。if only意为“但愿,要是...多好”,表示说话人的一种愿望。如果这个愿望是指现在或将来的,句子用过去时态,对于没有实现或不可能实现的愿望,要用过去完成时。ever意为“自...以来”,much as意为“尽管,虽然”。even though意为“即使,纵使”,均不合题意。

18.答案D。全句意思是:地球上已经发现有110种元素,其中大部分都是金属元素。在非限定性定语从句中,of可放在whom和which之前,而且that不能引导非限定性定语从句,C项位置排序错误,因此可先排除A、C两项。又因本题中心词elements是表示物而非人,故又可排除B项。

19.答案A。全句意思是:他经常给他的外祖母寄钱,并且她还有一小笔退休金。在引导定语从句时,代表人的关系代词如果作动词或介词的宾语时,要采用whom。在本题中,A项whom作介词to的宾语。

20.答案B。全句意思是:他是一位医生,他的妻子在生孩子以前也是医生。在英语中as作为连词使用时,其后可接\或do(或其他助动词)+主语”,表示“也”的含义。A、C、D三项均不具备此种语法作用。

21.答案A。全句意思是:无论你捡到什么东西都应当归还给失主。论什么”,在本题中,它既作这些功能。

22.答案C。全句意思是:这两者之间没有任何差别,我真不知该选哪一个。只能用“疑问词十不定式”作宾语。语,where不合题意,故23.答案D。全句意思是:作进一步的解释和说明。which,whose起连接作用时是关系代词或关系形容词,在引出的从句中起某种句子成分作用,而本题空缺处后面是一个结构完整的句子形式,不可能用关系代词或关系形容词。故24,答案B。全句意思是:磁最先是在指南针上得到实际应用。本题考查强调句型语,其关系代词that被省略掉了。故C项可排除。

25.答案B。全句意思是:他肯定会参加这次会议。当若用于否定或疑问结构时,后面的从句常用26.答案B。全句意思是:我们需要这种能够耐高温和高压的材料。该句中能和可先排除C、D项。根据句意,空缺处应填一关系代词,引出定语从句。当主句中有从句,但此时that是连接词,而不是关系代词,它引出的是表示结果的状语从句。本题中,引导定语从句,在句中作主语,故为正确答案27.答案B。全句意思是:我认为与其说亨利是一位作家,倒不如说他是位记者。法,意为“与其说...不如说不如说海洋联结了世界。因而可排除28.答案B。全句意思是:如果你学习下一课,就也知道得更多的条件状语从句,后面的分句说明该从句所引起的结果。more too.Otherwise29.答案D。全句意思是:无论她多晚回来,妈妈都会等她一起吃晚饭。这是一个让步状语从句,是一个作副词的修饰词,它要放在所修饰的词前,故可首先排除倒装语序,故也应排除。30.答案A。全句意思是:little,much为先行词表示某物或后接某物时,通常用关系代词whose指人、指物都可以,它在定语从句中作定语。这里的 whatever相当于no matter what,意为“不it is的表语,又作have found的宾语,还引导让步状语从句,其他几项均不具备know不能直接用不定式作宾语,B、D两项明显错误,可首先排除。根据句意,疑问词应作choose的宾C项为正确答案。

that在该句中引导同位语从句,对thoughts同位语从句通常用在thought,facts,news,idea,evidence,proof等名词之后。what,D项为正确答案。

\was...that...”。本题强调状A、C项为干扰项。若选C项,就是强调主语,而that从句中已有主语magnetism,doubt用在肯定结构中,一般用whether(或if)引导从句;that引导。

such构成搭配的只有as和that,such时,that也可引出as作为关系代词,o

“not so much...as”是一习惯用...”。又如Oceans don't so much divide the world as unite it.与其说海洋分隔了世界,A、C、D三项。

o“祈使句+and...”这一结构相当于一个if引导本题可改为:If you study the next lesson you will know or else表达“否则,要不然”之意;but表示“但是,可是”之意,均不正确。

however本身B、C两项。从句要用陈述语气,而A项用 当all,any,everything,a few,the only one,that,而不用which引导定语从句。关系代词the little指物,不能用关系代词who。
