如何巧用线索法做完形填空题所谓线索法，指的是根据文章上下文所提供的故事背景和语境线索进行推理和判断，从而确定最佳答案。具体说来有以下几种行之有效的方法。1．巧用语意转折线索解题有些句子含有表示转折或对比的连词、副词或副词短语，如but, though, although, instead, however, on the contrary, otherwise等，我们可利用这些暗示来解决问题。有时也可能没有这些词语的出现。如：A formal letter is very different from an informal letter. Formal letters ___1___ to businesses, schools or government offices. ___2___ letters are for relatives, or former(以前的) teachers. You may write an informal letter by hand, but you should ___3___ a formal letter.1. A. send B. are writtenC. write D. are dropped2. A. InformalB. FormalC. BusinessD. Relative3. A. copyB. typeC. writeD. share【解析】1. 选B。该句缺少谓语动词，而写信应用被动语态。该句意为“正式书信是写给商业部门、学校……”。D虽用了被动，但搭配不当。drop sb a line为“给人写信(短信)”。2. 选A。前面说的是正式书信，这里说的是写给亲戚、好友或以前的老师的，较随便，即非正式书信。3. 选B。通过but可知，此处说的是非正式书信与正式书信的写作方式的不同，非正式书信可以手写，但正式书信要正规得多，得打字。2．巧用因果关系线索解题即根据上下文的因果关系进行推断，从而得出所需答案。如：It was a strange noise that made the man ___1___ his car soon after he left a village ___2___ London. He got out of his car and ___3___ the wheels(车轮) carefully, but as he found nothing ___4___ he continued his way. 1. A. start B. stop C. slowD. speed 2. A. to B. forC. fromD. of 3. A. repaired B. examinedC. cleanedD. looked 4. A. wrong B. dangerC. interestingD. matter【解析】1. 选B。他在去伦敦的路上，一阵奇怪的声音驱使他把车停了下来。这可从He got out of his car…推测出来。 2. 选B。leave…for…是个固定短语，意为“离开……到……”。 3. 选B。在听到奇怪的声音后，他停下车来仔细检查轮胎(看看出现了什么问题)。 4. 选A。从下句“他又继续赶路了”可知，“因为他没有发现毛病”。nothing wrong意为“没有毛病”。3．巧用具体示例线索解题即根据文章中所提供的具体实例进行分析，将与具体示例有关的信息进行优选，将与具体示例无关的信息进行排除，从而便可得出所需答案。如：Every student must wear their ___1___ when they are at school. There are ___2___ items of uniforms: suits, dresses, shorts, skirts and T-shirts. There are also Wasley schoolbags, caps and socks.1. A. long hairB. thick glassesC. sports shoesD. school uniforms2. A. much B. threeC. manyD. a lot 【解析】1. 选D。本段谈论的是在校生穿校服的事情，而不是穿运动鞋，蓄长发、戴墨镜并不是学校所提倡的。 2. 选C。suits, dresses, shorts, skirts and T-shirts等是服装的个例，前面只有填“校服”才与之相配。 [1][2][3]下一页 说明:引用此文请注明出处,并请保留该文章链接地址,谢谢~~4．巧用同义反义线索解题Though he is serious in appearance, he never fails to be interesting. Often he is clever, sometimes even ______ and gay…A. worried B. bright C. discouragingD. friendly【解析】从Often he is clever来看，此处话题谈论的是“他的智慧/聪明”，而even一词也暗示此处应填bright，因bright与clever为同义词，均为“聪明”。As it turned out, my little publication went on to become Student, a national magazine for young people in the U.K. My wife and I have two children, and I’d like to think we are bringing them up in the same way Dad ______ me. A. controlled B. comforted C. reminded D. raised【解析】句中的 in the same way 告诉我们，空格处所填动词应与前面的动词 bring up(培养，养育)同义，比较四个选项，答案显然是 D项。5．巧用逻辑顺序线索解题即根据文章所提供的内容，同时结合一定的生活常识，对所推断的内容进行逻辑推理和逻辑顺序。如：I went to Wasley College with Winnic today. Wasley is a large, old ___1___. It has three branch campuses(分校): Clunes, Glen Waverly and Elasterwick. It has a primary school, a ___2___ school and a senior school. So there are twelve grades of ___3___ studying there.1. A. schoolB. factoryC. movieD. hospital2. A. nightB. junior C. highD. spare-time3. A. worker
