大学英语四级考试之听力理解篇 7大句子填空设题处 句子填空要求考生写出所空句子原文或其要点。根据历年真题，四级短文听写所考查句子的长度都在11-23个单词之内，句子结构大都比较复杂，通常为并列句或主从复合句。 常见的设题处有： 1。与主题密切相关的细节内容 2。段落首尾句 3。并列、转折等结构处 4。对比及比较结构处 5。含有从句的句子 6。含有非谓语动词短语或独立结构的句子 7。含有年代等数字的句子 一、与主题密切相关的细节内容 段落的主题一般已给出，要求考生补全支撑细节。 [例1](97-6) Sometimes, it’s dangerous. One day for example, I was working undercover,… . I was trying to catch some robbers who were stealing money from people as they walked down the street. Suddenly, (S8) seven bad man jumped out at me; one of them had a knife, and we got into a fight. (本句描述的正是用来说明警察工作危险的细节） 二、段落首尾句 段落的主题句或概括性的结论多出现在段首或段尾，这些句子是句子填空的主要设题点之一。 [例2] (02-12) (S10) It would make sense to give the fish enough time to recover, grow to full size and reproduce, then catch them in a way that doesn’t kill other innocent sea life. (本句为本文的最后一句，是全文的结论句) 三、并列、转折等结构处 这类句子一般含有and, as well as, but, whereas, while 等标志性词语。 [例3] (97-6) Another day, I helped a woman who was going to have a baby. (S9) She was trying to get to the hospital, but there was a bad traffic jam. (本句是由but连接的两个构成转折关系的并列句) 四、对比及比较结构处 含有比较级、最高级，以及as…as, compared with, in contrast等引出的比较结构的句子常常是短文听写的设题重点之一。 [例4] (05-1) Indeed one of the other models we looked at weighed almost twice as much. (S9) Similarly, it is smaller than most of its competitors, thus fitting easily into a pocket or a handbag. (本句中含有比较结构smaller than) 五、含有从句的句子 短文听写很少有句子是简单句。因此含有状语从句、同位语从句或定语从句的复合句往往是其设题的重点。 [例5](98-1) Another challenge was his size. (S8) High school physical education was difficult because all of the equipment was too big for the then 5-year-old student. (本句含有because 引导的原因状语从句) 六、含有非谓语动词短语或独立结构的句子 含有不定式、动名词、分词短语或分词的独立结构的句子往往也是短文听写重点考查的句式之一。 [例6] (98-1) He likes computers so much (S9) that in graduate school he’s studying how to make them like people. He wants to make robots do all the heavy tasks.(本句中包含“疑问词+不定式”结构，在句中充当宾语) 七、含年代等数字的句子 带有数字（年代、增长降低的数据，百分比，比分等）也是考查的重点 [例7](04-6) In 1897, the library moved to its own building, across th
