九、many 与 much的用法区别

两者都表示“许多”,但 many 修饰或代替可数名词(复数),与 few(少数)相对;而 much 用来修饰或代替不可数名词(单数),与little(少量)相对。在口语中两者主要用于非肯定句中:

Did you see many people there? 你在那儿看见许多人了吗?

We don’t have much time. 我们没有许多时间。

在肯定句中,一般用 a lot of, lots of, plenty of 等代之。但在正式文体中有时也用于肯定句中;另外,若用作主语或主语的定语,或其前有 how, too, as, so, a good, a great 等修饰,也可用于肯定句中:

Many of us left early. 我们有许多人离开得很早。

Much work has been done. 许多工作都已经做了。

You’ve given me too much. 你已给我太多了。

Take as many (much) as you want. 你要多少拿多少。

I asked her a great many questions. 我问了她许多问题。

十、few, a few 与 little, a little的用法区别

1. few和a few 后接可数名词的复数形式。few 表示数量很少或几乎没有,强调“少”,含有否定意义;a few 表示数量虽然少但毕竟还有,强调“有”,含有肯定意义:

It is very difficult, and few people understand it. 它很难,没有几个人能懂。

It is very difficult, but a few people understand it. 他虽难,但是有些人懂。

2. little 和 a little 之后接不可数名词,其区别跟 few 和 a few 之间的区别相似:

Unfortunately, I had little money on me. 很不巧,我身上没带什么钱。

Fortunately, I had a little money on me. 幸好我身上带着一点钱。

几组不定代词用法区别:

不定代词是历年来考试中考查最多的一类。在学习过程中应特别注意以下几组代词的用法:

  一 . some 与 any 的用法

1. some 用于肯定句以及表示建议或期待得到肯定回答的问句。修饰单数名词时,意为“某个”。如:

I have some questions about the assignment.

Would you mind buying me some sweet?

(希望得到肯定答复)。

2. any 用于否定句和疑问句时,表示“一些”。用于肯定句时,只和单数名词或不可数名词连用,表示“任何”。如:

The medicine is on sale every where. You can get it at any chemist's.

  二 . each 与 every 的用法

1. each 强调个体,表示两个或两个以上中的“每一个”,在句中可充当主语、宾语、定语和同位语。如:

There are trees and flowers at each side of the road.

2. every 强调整体,表示三者或三者以上中的“每一个”,只能作定语,不能说 every of them ,要说 every one of them .如:

Every student in our class works hard.

  三 . no one 与 none 的用法

1. no one 意为“没有人”,只能指人,不能指物,不可与介词 of 连用,谓语动词用单数形式,回答 who 引导的问句。如:

— Who is in the classroom?

— No one.

2. none 既可指人,也可指物,强调数量,意为“一点也不,一个也不”;谓语动词既可用单数也可用复数;常与 of 连用,通常指“三者以上的人或物中没有一个”,回答 how much 和 how many 引导的问句。如:

They were all tired, but none of them would stop to have a rest.

  四 . other, another, others, any other, the other 的用法

1. other 表示泛指,意为“另外的、其它的”。常与复数名词或不可数名词连用。如果其前有 the, this, some, any, each, every, no, one 以及形容词性物主代词时,其后就可接单数名词。如:

I have no other place to go.

2. another 常用于指三者或三者以上中的“另外一个”,泛指单数。可单独使用,也可后接名词。如果其后接复数名词,则表示“又、再、还”。如:

This cap is too small for me. Show me another (one)。

We need another three assistants in our shop.

3. others :它是 other 的复数形式,表示泛指,意为“别的人或物”,但不指全部。特指时在其前加定冠词;前面可加任何限定词以及数量词。如:

He has more concern for others than for himself.

4. any other 表示一个之外的其他任何一个,而不是两个之中的另一个。如:

China is larger than any other country in Asia.

5. the other :表示两者中的另外一个。可单独使用,也可接单数名词。如:

No agreement was reached in the discussion as neither side would give way to the other.

  五 . all 与 both 的用法

均表示“都”,但 all 表示三者以上的人或物, both 则表示两个人或物。二者都表示肯定意义,如果与 not 连用时,则表示部分否定。

  六 . neither 与 either 的用法

都可用于表示两个人或物。 neither 表否定意义,意为“(两者中的每一个)都不”;而 either 表肯定意义,意为“(两者中的每一个)都”。都可单独使用,也可同介词 of 连用。如:

Both teams were in hard training; neither willing to lose the game.

— Do you want tea or coffee?

— Either. I really don't mind.

七 . it, one 和 that

1. it 可指代可数名词和不可数名词。常常指代上文中“ the+ 名词”或“物主代词 + 名词”中的名词,表示同一件事物,但 it 代替的事物属于特指。它的复数形式是 they 或 them .如:

The Parkers bought a new house but it will need a lot of work before they can move in.

2. one 所表示的名词(可指人或物)和前面所提到的名词只是同一类中的任何一个,不是指其中某一个。不能代替不可数名词。复数形式是 ones .如:

I hope there are enough glasses for each guest to have one.

3. That 指代的也是同一类事物而不是同一个事物,但 that 代替的是有定冠词的名词,表特指,它还可以代替不可数名词。用 that 来代替前面已出现的可数名词( that 相当于 the one )或不可数名词时,后面一定要跟修饰语,且 that 只能指物。如:

No bread eaten by man is so sweet as that earned by his own labor.

总之,我们在使用不定代词时,一要注意指代的范围;二要注意是表示肯定还是否定;三要注意词性(它们还可用作形容词)。
