談?wù)?/FONT>quantity的語法特點(diǎn)

 

1. 表示數(shù)量,若是指相對(duì)于質(zhì)量來說的數(shù)量,是不可數(shù)名詞。如:

Quality is more important than quantity, but without quantity there can be no quality. 質(zhì)量比數(shù)量更重要,但沒有數(shù)量就沒有質(zhì)量。

2. 若指具體的數(shù)量,通常為可數(shù)名詞,此時(shí)可以連用不定冠詞或用復(fù)數(shù)形式;要表示數(shù)量的多少可用 great, large, huge, small 等形容詞修飾;既可用于修飾不可數(shù)名詞,也可用于修飾復(fù)數(shù)名詞。如:

He lost a great quantity of blood. 他失了大量的血。

Police found a small quantity of drugs in his possession. 警方發(fā)現(xiàn)他擁有大量(少量毒品)。

在某些表達(dá)中,quantity可以單獨(dú)表示大量(沒有large, great之類的修飾語)。如:

I was astonished by the sheer quantity of stuff in the trunk. 看到大箱子里的東西那么多,我感到十分驚訝。

3. 當(dāng)a great (large, small) quantity of結(jié)構(gòu)作主語時(shí),其謂語的數(shù)原則上與其中的名詞的數(shù)保持一致。如:

A large quantity of beer was sold. 售出了大量的啤酒。

但是,若該結(jié)構(gòu)變成quantities of(大量的)這樣的形式,則當(dāng)它用作主語時(shí),其謂語動(dòng)詞一律用復(fù)數(shù)(與其中名詞的數(shù)無關(guān))。如:

Quantities of books were on the desk. 在桌上有很多很多書。

Huge quantities of oil were spilling into the sea. 大量的石油滲到海里。

Quantities of food were spread out on the table. 許多食品攤放在桌子上。

4. 注意以下表達(dá)的用法:

(1) a quantity of 一些一批

We need a quantity of baskets. 我們需要一批籃子。

(2) in quantity 在數(shù)量方面;大量地,大批地

These goods are greater in quantity than in quality. 這些貨數(shù)量多,質(zhì)量一般。

It is much cheaper if you buy it in large quantity. 如果你大批購買會(huì)便宜很多。

比較:We don’t sell coal in small quantities. 小批的煤我們不賣。
