从 a huge amount of 和large amounts of说开去,兼谈a quantity of 和quantities of的用法(转摘)
外研版选修7 module3 里有a huge amount of词组。其用法为:a large(great,good)amount of +不可数名词,谓语动词一般用单数;但(huge,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 beend one by the earth quake.
Large amounts of money were spent on the bridge.
关于 a quantity of 和quantities of的用法:“a large quantity of 译为“许多,大量”其谓语由短语中的“quantity”形式决定。它是单数,不管修饰的是什么样的词,一律用单数。如果是quantities,则谓语全用复数。只与quantity的形式有关。
专家观点:
1. 徐广联在《大学英语语法讲座与测试》(华东理工大学出版社)中表示, a quantity of 只能修饰不可数名词,谓语动词用单数。 A quantity of 间或也可以修饰可数名词,例如, A quantity of baskets were on sale.
2.  张怀信在《英语高考活用图解辞典》(延边大学出版社)中讲到, a large/small quantity of 大量的/ 少量的(可以修饰可数名词或不可数名词),例如, I need a large quantity of oil (apples). quantities of 大批的,大量的,例如, Large quantities of polluted water are flowing into the sea. 该书所附〈语法祥解篇--- 主谓一致〉还明确指出“在以上( a lot of, lots of, plenty of, a large quantity of + 名词)的词组后面的名词是中心词,谓语动词根据后面的名词的数而定”。
3 .顾南华在《中高级英语考试指南》(华中工学院出版社)中说, a quantity of, quantities of 可跟可数名词与不可数名词, 并举有三例: There is a large quantity of milk. Great quantities of fish are caught on the high sea. Large quantitie
