Unit 6 Mainly revision

典型例题

　　1.______ is a good form of exercises for both young and old.
　　A.The walk　　B.Walking　　C.To walk　　D.Walk 答案:B
　　本题考察分为语动词的用法，具体说，本题就是要辨别名词做主语，不定式做主语和动名词做主语的区别。 a walk 或 the walk 做名词时，应指某一次的散步，如：What about taking a walk?本题是指“三步”这件事，不指某一次散步，而表示抽象的一般意义的概念，用动名词形式最合适，故最佳答案是B.

　　2.Go and get your coat. It’s ________ you left it.(NMET 92)
　　A.there　　B.where　　C.there where　　D.where there 答案：B
　　解析：本题考察引导名词性从句的连接词的用法。选项C,D明显不合语法，首先予以排除。It’s后面的部分是表语从句，where 可引导一个从句，同时其本身也在从句中作状语，where 正和题意。选项A错误。由于表语从句需有连接副词引导，there不是连接副词，不可以引导句子。

　　3．You can’t leave the classroom without _______ by the teacher.
　　A.permitted　　B.being permitted
　　C.permitting　　D.having permitted
　　解析：本题的正确答案是B.选项中A中permitted 使过去分词形式不能做介词宾语，选项C中permitting ,选项D中having permitted 分别是动词-ing 形式主动形式的一般式和完成式，在这里都不正确。如：
　　He walked away from home on a dark night without being seen.

　　4.He had a high fever when he was three,and making him completely blind.
　　词题中应去掉and.动词应去掉连词and,动词-ing形式短语making him completely blind 用作状语，做补充说明或表是结果。如：
　　The child fell,striking his head against the door and cutting it.小孩跌到了，头撞在门上，划破了。

　　5.Have you visited the factory______ such goods?
　　A.produced　　B.to produce　　
　　C.producing　　D.is producing
　　解析：现在分词作定语表主动，进行。答案：D.

　　6.________ his exercises, he went out.
　　A.Having finished　　B.Finished
　　C.Finishing　　　　　D.Being finished
　　解析：现在分词完成时作状语，其行为先于谓语发生。答案：A.

　　7.The street is lined with_______.
　　A.newly built buildings　　B.buildings newly built

　　解析：单个的过去分词或副词＋单个过去分词作前置定语。答案：A
