例1、_____ he did not know much English,he got out his dictionary and looked up the word.

A. As   B. For   C. Since   D. Because

答案为A

[解析]for,because和as虽皆可作连词用,都可表示“因为”,但用法有些区别。for引导的分句总是置于另一分句之后,常常对前一分句加以解释,两个分句之间,总是用逗号分开。because引导的原因状语从句时,往往以why问句,语气比较重,传递的往往是对方未了解的新信息。as引导的原因状语从句时,往往是对方也知道的信息。本句是他拿出词典查,显然,“他知道的英语单词不多”,这是明摆着的事,所以用as最恰当。

例2. John became a football coach in Sealion Middle School ____ the beginning of March.

   A. on           B. for               C. with          D. at

答案:D

[解析] at the beginning of “在………的开始”。

例3. -How far apart do they live?

-_________ I know ,they live in the same neighbourhood.

A. As long as   B. As far as    C. As well as    D. As often as

答案为B

[解析]  首先应分析这四个短语的意义区别。这是四个意义完全不同的短语。as long as 意为“只要……就”;as far as意为“到目前为止”;as well as意为“也……”;as often as意为“每次,每当”,根据原题as far as I know意为“就我所知”。

例4. The speech by the mayor of Shanghai before the final voting for EXPO 2010 is strongly impressed_________ my memory.

A. to     B. over     C. by      D. on

答案为D。

[解析]  impress sb . (with sth.)给某人深刻印象。impress on/upon sb.是固定搭配,给……留下印象。

例5. The home improvements have taken what little there is_________ my spare time.

A. from     B. in     C. of     D. at

答案为C。

[解析]  这是一个宾语从句,have taken后接感叹句,其正常语序是what little of my spare time there is.

例6. The sunlight came in ________the windows in the roof and lit up the whole room.

A. through     B. across     C. on     D. over

答案为A。

[解析]  “从窗户缝隙中”要用介词through。through指从里面穿过,透过;across强调从面上横穿,横跨;on“在……面上”;over从一地到另一地;经过一段时间或距离。译文:阳光从屋顶窗户缝隙中照射进来,把整个屋子都照亮了。

例7. He was about to tell me the secret _______  someone patted him on the shoulder.

A. as     B. until     C. while     D. when

答案为D。

[解析]  as, until, while和when均可表时间,但各有不同:as强调一边……一边;while“在……期间/同时”,表转折;when有两种用法:①当……时,从句动词不限;②就在此时,忽然,等于at that time, suddenly。常用的句式有:be doing…when…(正在做……突?然……);?be about to do…when(正要做……突然……);常与when连用。译文:他正要告诉我这个秘密,这时,有人拍了拍他的肩膀。

例8. I know nothing about the young lady ________  She is from Beijing.

A. except     B. except for   C. except that  D. besides

答案为C。

[解析]  except后接名词或代词,意思是“除……之外”,表示从整体中除掉部分。except for后接名词或代词,意思是“除……之外”,表示两种事物的类比。如:Your composition is very good, except for some mistakes.作文和错误是两个概念。except that引导句子。besides后接名词或代词,前边常有other,else等,意思是“除……以外还有”。she is from Beijing是一个句子,只有except that才能引导从句。

例9. Don't be afraid of asking for help _____ it is needed.

A. unless    B. since    C. although    D. when

答案为D。

[解析]  考连词的用法及区别。答案D容易和B混淆。这里的when=if(如果、倘若)。根据句子的前后关系,应该是未发生的事情,但由when引导的时间/条件状语从句中谓语动词应用一般现在时代替一般将来时。而since(既然)引导的是原因状语从句,其谓语若是将来时,不可用一般现在时代替。译文:如果需要,就别怕向人求助。

例10. They had a pleasant chat_________ a cup of coffee.

A. for     B. with     C. during    D. over

答案为D。

[解析] 考查介词搭配。to chat over a cup of coffee意思是边喝咖啡边聊天。for和during都有“在……期间”之意,但后边通常加时间;with“随着,用”;over“在(做)……期间,边……边……”。
