amount用作名詞和動詞的語法特點

1. 用作名詞，意為“數(shù)量”“金額”等，通常用于 a (great, large) amount of 這類結(jié)構(gòu)，其后通常接不可數(shù)名詞；這類結(jié)構(gòu)用作主語，其謂語的數(shù)取決于 amount 的數(shù)。如：

在這座橋上花了大量資金。

正：A large amount of money was spent on the bridge.

正：Large amounts of money were spent on the bridge.

偶爾也可見到其后接復(fù)數(shù)可數(shù)名詞的用法，但不算普通。如：

The shopkeeper had a large amount of oranges in his storeroom. 店主在貨倉里存有大量橙子。

Even small amounts of these substances are known to cause skin problems. 我們知道這種物質(zhì)即使是一丁點也會損害皮膚。

2. 用作動詞，意為“合計”“等于”“意味著”，通常是不及物動詞，其后常接介詞 to。如：

The cost amounted to 250 pounds. 費用共達(dá)250英鎊。

It all amounts to a lot of hard work. 這一切就相當(dāng)于很多繁重的工作。

Her resignation amounts to an admission of failure. 她的辭職等于承認(rèn)失敗。

由于其中的to為介詞，所以后接動詞時要用動名詞。如：

This amounts to cheating the teacher. 這等于欺騙老師。

This amounts to doing the whole thing over again. 這等于要把整個事重做一遍。
