专八改错练习及详解(7)

补充：
第二题将amount改为amounts也是正确的
第四题把hold改为holding也是正确的
a small amount of 和small amounts of 用法的区别
a large（great，good）amount of ＋不可数名词，谓语动词一般用单数；但（large，great，good）amounts of ＋ 不可数名词，作主语时，谓语动词要用复数。
A large amount of damage ＜has been＞done by the earth quake．
Large amounts of money ＜were＞spent on the bridge．
这就是为什么第二题也可以把amount改为amounts而第八题不用改amount的原因啦.
