连词考点
◆典型陷阱题分析◆
1. I’m sorry, _____ I won’t be able to come tonight.
A. for B. and
C. but D. then
【陷阱】容易误选A，因为空格后的句子是用以说明 I’m sorry 的原因的，所以便想当然地认为要选for来表示原因。
【分析】事实上，I’m sorry 后习惯上不接表示原因的连词 for，而接表示转折的连词 but（也可省略 but），用以委婉地提出一个使对方不快的事实。又如：
Oh, sorry, but she’s out. 哦，不好意思，她出去了。
I’m sorry, but I have to disagree. 对不起，我不敢苟同。
I’m sorry, but I have already had another appointment. 对不起，我已经有约会了。
注：I’m sorry 后虽然不能接表原因的连词for，但却可接介词 for。如：
I’m sorry for shouting at you. 对不起冲你嚷嚷了。
I am sorry for what I said to you. 我后悔不该对你讲那些话。
2. The point is not who said the words, _____ they are true or not.
A. but whether B. and whether
C. but how D. and how
【陷阱】几个干扰项均有可能误选。
【分析】最佳答案为A。此题涉及两个搭配：一是 not … but …（不是……而是……），二是 whether … or not (是否)。请看类例：
He was not an actor, who often appeared on stage, _____ a writer, writing stories.
A. but B. and
C. then D. so
答案选A，主要考查 not … but … 结构。
3. Just because they make more money than I do, _____ they seem to look down on me.
A. so B. and
C. but D. 不填
【陷阱】但容易误选A，将汉语的“因为……所以……”直译为 because … so …。
【分析】此题正确答案为D，但是按英语语法，because 为从属连词，用以引导原因状语从句，它表明整个句子为复合句；而 so 在表示“所以”时，它是并列连词，用以连接两个简单句使之成为并列句。由于在同一句中既用了从属连词 because，又用了并列连词 so，使得该句一半像复合句，一半像并列句，从而导致错误。正确的做法是，任意去掉 because 和 so 中的一个，使之要么成为复合句，要么成为并列句。
4. Although he had only entered the contest for fun, _____ he won first prize.
A. but B. and
C. even D. 不填
【陷阱】容易误选A，将汉语的“虽然……但是……”直译为 although … but …。
【分析】正确答案选D。按英语语法，although 为从属连词，用以引导让步状语从句，它表明整个句子为复合句；而 but 在表示“但是”时，它是并列连词，用以连接两个简单句使之成为并列句。由于在同一句中既用了从属连词 although，又用了并列连词 but ，使得该句一半像复合句，一半像并列句，从而导致错误。正确的做法是，任意去掉 although 和 but 中的一个，使之要么成为复合句，要么成为并列句。其实，此题与上面一题的分析思路是一样的。这里顺便说一句，许多同学(包括许多老师和教学参考书)为了便于记忆，将此题与上面一题的知识点简单地归纳为“按英语习惯，because和so不可连用，although 与 but 不可连用”。这种说法在通常情况下无疑是对的，也是有效的，但同学们一定要在明白以上道理的情况下来使用此规则，如果只是死记该规则，有时遇到一些语言特例仍然会出错。如：
But I didn’t know that then, although I learned it later. 但我当时的确不知道此事，尽管后来我还是知道了。
此句既用了并列连词 but，又用了从属连词 although，但它并未造成错误，原因是此句与上面所讨论的情形有所不同，即此句 but 用于 although 之前，but 在此仅起到与上文转折的作用，but 后的 I didn’t know that then, although I learned it later. 仍为一个复合句。
I tried doing the accounts, but although I knew some maths I found it very difficult. 我试着算这些账，但尽管我懂点数学，仍感到很困难。
此句将 but 与 although 用在一起，但此句也没有错误。该句从总体来看，它是一个以并列连词 but 连接的并列句，而在该并列句的后面一句又是一个包含让步状语从句 although I knew some maths 的复合句——这种句型就是所谓的并列复合句。此句也可改写为 I tried doing the accounts, but I found it very difficult although I knew some maths.
5. When the last prize had been awarded _____ everybody cleared off.
A. and B. so
C. or D. 不填
【陷阱】容易想当然地误选A。
【分析】句首 when 引导的是一个时间状语从句，它暗示整个句子为复合句；而so, and, or 为并列连词，无论选哪一个，都表明整个句子为并列句，从而导致前后矛盾，所以A、B、C均不能选择。此题正确答案选D，everybody cleared off 为整个复合句的主句。请看类似例子：
(1) If wishes were horses, _____ beggars would ride.
A. and B. so
C. or D. 不填
(2) If I’m mistaken, _____ you are mistaken too.
A. so B. and
C. or D. 不填
(3) Just before I left London, _____ I sent him a telegram.
A. and B. so
C. or D. 不填
(4) After they had each said a few words, _____ Lloyd George took the floor.
A. and B. so
C. or D. 不填
答案均选D，空格前分别为 if, when, before, after 引导的状语从句，空格后为整个复合句的主句。

【答案与解析】
1. 选D，第一空填 or，表选择；第二空填 and，can’t drink and drive 指不能同时既喝酒又开车，即不能酒后开车。
2. 选C，句意为“这家酒店开门到什么?（或这家酒店什么时候关门?）”
3. 选C，选项A用No来回答选择疑问句，不妥；选项B用 and 连接 tea 与 coffee，说明问句并非提供选择，而答语却用了 either 这样表选择性的词语，也不妥；选项D与语境不符。
4. 选D，前后意思转折，故选 but。注：but they do = but they like him。
5. 选C，that 为引导宾语从句的连词，在 that what he said at the meeting was right 这一宾语从句中，又包含有what he said at the meeting 这一主语从句，而在该主语从句中，what用作动词 said 的宾语。
6. 选B，or 表选择。
7. 选C。how 修饰谓语动词 treated。
8. 选B，从句意推知。
9. 选A，when 在此用作并列连词，意为“这时(突然)”。
10. 选C。第一空填 or，在否定词后用or，表示否定两者；第二空填but，表示转折。
11. 选D。but表转折，符合语意。而表并列的and， 结果的so，原因的as都不符合句意。
