1、专题六 连词易错清单1. as,while,when,as用作连词时,含义比较多,A)引导时间状语从句。(1)用“as soon as”结构,意思是“一就”。例如:Please e-mail me as soon as you get there.请你一到那里就给我发电子邮件。Ill tell him the news as soon as he comes back.他一回来我就把这个消息告诉他。(2)作“与同时、一边一边、当的时候”讲时,强调主从句的动作同时发生,而从句的谓语动词必须是延续性动词。例如:He read the letter as he walked along the ri

2、ver.他一边沿着河边走,一边读信。As I waited at the stop, I heard a big noise.我在车站候车的时候,听到了一声巨响。B)引导比较状语从句。用于“as.as”结构中,第一个as是副词,第二个as是连词。否定句用not as/so.as结构。例如:He sings as well as his brother. 他唱歌和哥哥一样好。Canoeing is not as/so interesting as sailing.划独木舟没有航海有趣。C)引导原因状语从句。表示明显的原因,意思是“由于、鉴于”。例如:We all like her as she

3、is kind. 我们都喜欢她,因为她善良。As youre tired, youd better have a rest. 因为你疲劳,你最好休息一下。D)引导让步状语从句。作“虽然、尽管”讲时,相当于though,但是没有as常用。例如:As/Though they were tired,they still walked on. 尽管很累,他们还是继续走。 (=Tired as/though they were,they still walked on.)As I like it,I will not buy it.虽然我喜欢这个东西,但是我不想买。E)引导方式状语从句,意为“按照、如同

5、.but also.不但而且(12)both.and.既又as用作介词,意为“如同、作为、当作”,与介词like不同,as表示某人/物看起来完全一样或几乎相同,而表示相似关系,但不等同。如:Dont have him as a servant. 不要把他看作仆人。He works as a servant. 他以仆人的身份工作着。试比较:He works like a servant. 他像仆人一样工作。 (实际上不是。)as作“作为”讲时,相当于being。如:As a student,its bad manners to be late for class. 作为学生,迟到是不礼貌的。(=

6、Being a student,its bad manners to be late for class.)as常与动词连用,构成短语或固定搭配如:look upon.as把看作;regard.as把认为是/把看作;act as担任、充当等。as用作副词,意思是“同样地”,通常用来修饰副词或形容词。如:He works hard,but I study just as hard.他努力学习,我学习也一样努力。Their shool is as beautiful as ours.他们的学校和我们的学校一样美丽。when用作连词,引导时间状语从句,意为“当的时候”。如:She wants to

11、cause就不用so,用so就不用because。试比较:Nick caught a bad cold yesterday,so he had to stay at home.Because Nick caught a bad cold yesterday,he had to stay at home. 尼克昨天得了重感冒,因此他不得不待在家里。because 可以与of连用,构成介词短语 because of,之后跟名词、代词、词组或短语表示理由/原因。如:He has poor eyesight because of doing lots of computer work.由于做大量的电脑

12、工作,他的视力差。The match was put off because of the bad weather.比赛由于天气不好被推迟了。since 表达明显的或已知的理由,意为“既然”。since 引导的从句常用于句首,语气不如because,但是比as语气强。引导的从句位于句子末尾时,可以作为补充说明。如:Since everybody is here,lets begin.既然大家都到了,那我们就开始吧。Since you dont want to go there,I wont force you to.既然你不想去,我也不勉强你。Ill go to ask someone els

17、那么多,我们的小汽车过不去。so.that.可以与以下结构转换:A. 与too.to.结构的转换too.to.意为“太而不能”,与so.that.结构互换时,that从句中必须使用情态动词cant(如果是过去时则用couldnt)。如:He was so clever that he couldnt make such stupid mistakes. He was too clever to make such stupid mistakes. 他太聪明了,不会犯这么愚蠢的错误。温馨提示:如果主从句的主语不一致,改为同义句时,要用too.for sb. to.结构。如:That questi

18、on is so difficult that I cant work it out. That question is too difficult for me to work out. 这个问题太难,我算不出来。B. 与enough to do/not enough to do 结构的转换a)与enough to do sth. 结构的转换。enough to do sth.意为“足够做某事”,与so.that.结构转换时,that从句中必须使用情态动词can。如:You are so healthy that you can get back to school. You are hea

19、lthy enough to get back to school. 你身体健康,可以回学校去了。b)与not.enough to do结构的转换。not.enough to do意为“没到做某事的”,与so.that.结构转换时,that从句中必须使用含有否定意义的情态动词。enough前面的形容词是so.that.结构中so后面形容词的反义词。如:The boy is so young that he cant dress himself.

20、nt that he cant wait.

22、受到的教育很少以至于他找不到工作。提分策略连词的考查在近几年的中考题中出现率较高,测试内容涉及并列连词的用法、时间状语从句、让步状语从句等。遇到有关连词的单项选择题时,考生需注意下面的问题:1. 简单连词的选择首先找出连词在句中是连接词与词、短语与短语还是连接句子与句子,以此来确定用并列连词还是从属连词。如果选择并列连词,应该根据具体的语境,通过句意来确定应该用表示平行或承接关系的连词、选择关系的并列连词还是表示因果关系的并列连词。【例1】(2014北京24)Id like to go with you, Im too busy. A. orB. andC. soD. but【解析】考查连词的

23、用法。由后一句中的“too busy”判断,应该用but来连接,表示转折,不是选择、递进或因果。 故选D。【答案】D【例2】(2014江西30) jeans were invented over 100 years ago,theyre still in fashion today.A. BecauseB. IfC. AlthoughD. Since【解析】考查连词的用法。 由句子关系和句意“100多年前发明牛仔裤,现在仍然时髦”判断,该句是让步状语从句。故选C。【答案】C2. 复合连词和短语连词的选择。复合连词和短语连词可以引导并列句和各种不同的复合句。常见的有:both.and.;eith

24、er.or.;neither.nor.;as well;not only.but also;as soon as【例】(2013内蒙古包头32)One important aim of our school is to prepare us for the future we can face all the challenges with confidence.A. so farB. so thatC. even ifD. if only【解析】考查短语连词的辨析。 so far到目前为止;so that 以至于;even if 即使;if only 如果;由句意“我们学校的一个重要目标是为

25、我们的将来做准备以至于我们能够有信心面对各种挑战”判断,该句是因果关系,应该用短语连词so that来连接。故选B。【答案】B3. 从属连词的选择如果需要选择从属连词,应该根据主句与从句之间的关系确定是宾语从句还是状语从句。如果是状语从句,还要根据句意分析,从句是表示时间、条件、原因还是结果等。 然后确定所需的连词。【例1】(2014河南34)Hes not a perfect child. He sometimes talks back his parents talks with him.A. ifB. beforeC. whenD. until【解析】考查连词的用法。由句意“他不是个完美

26、的孩子,他父母和他谈话时,他有时顶嘴”和句子之间的关系判断,该句是时间状语从句,不是条件状语从句。因为主句和从句的动作同时发生,不是前后发生的或“直到为止”。故选 C。【答案】C【例2】(2013浙江义乌19)Ill probably stay with my friends I get my own place to live in.A. beforeB. whenC. afterD. because【解析】考查连词的用法。这是一个含有时间状语从句的复合句。A项表示“在以前”,B项表示“当的时候”,C项表示“在之后”,D项表示“因为”。根据句意:“在我有自己的房子之前,我很可能和我的朋友们住
