(1) 其后接名词时,该名词通常应是特指的(比如有the, these, those, my, our, Tom's等修饰)。如:
Many of the farmers grow rice. 很多农民种稻子。
Many of his ideas were amusing to her. 他的许多想法使她感到有趣。
He spends much of his time outdoors. 他很多时间都在户外度过。
Much of the land was flooded. 大片土地被水淹没。
(2) 如果名词没有表特指的限定词,通常就不用of。如:
误:She didn't eat much of breakfast.
正:She didn't eat much breakfast.
误:There aren't many of large glasses left.
正:There aren't many large glasses left.
(3) 如果用了介词of又没有特指限定词,通常是不可以的。如:
误:Many of students have read it.
正:Many of the students have read it. 许多学生读过它。
误:Much of time was wasted.
正:Much of the time was wasted. 大部分时间都浪费了。
(4) 在少数情况下,much of之后不跟限定词也可以用,这主要见后接人名和地名的情形。如:
Not much of Denmark is hilly. 丹麦山地不多。
I've seen too much of Howard recently. 最近我见霍华德见得太多了。
(5) 在人称代词前总是用many of或much of,其中的of不能没有。如:
I didn't eat much of it. 这个我没吃多少。
Many of us were too tired to go further. 我们很多人都累得不能再往前走了。
(6) much of有时可用于一个还有不定冠词的名词前。如:
You can't see much of a country in a week. 一周之内看一个国家看不了多少地方。
How much of a job would it be to rebuild the garage? 重建这个车库工作量会是多少?
not much of a 有时可用于名词前表示某人对某物或某人评价不高。如:
Then he's not much of a partner. 那时他不是什么了不起的合伙人。
That might not seem like much of an accomplishment. 那似乎算不上什么成就。
