microcystisUID: 162156

1. The composition leaves _____for revision.
A. much room   B. great deal room C. a small room  D.no so big room

选A，room是不可数，意为这篇作文留了很多空间需要修订

7. He is very tired. He needs ______.
   A. a night rest    B. a rest night    C. a night’s rest   D. a rest of night

偶不能确定是A或者C，不过按照感觉是A，感觉上去BCD都和A有一些联系，都象是A的迷惑选项

20. There are _____ in her new house.

A. many furnitures                         B. much furniture
C. many pieces of furniture           D. a lot of furnitures

肯定是C，不可能是D，furniture做集合名词不可数，类似于people的用法
