关于quantity和amount

Answer 1

1.Large quantities of money are spent on the subject. 这个句子中要以quantities为中心词,所以用are,如果quantities换成amounts,也把amounts看做中心词. 2.*(large)quantities of 修饰可数名词复数或不可数名词,其短语做主语时,谓语动词典一般用复数. eg. Large quantities of food/nuts were on the table. *(large) amounts of 修饰不可数名词，其短语做主语时,谓语动词典一般用复数. eg. Large amounts of money are spent on the subject. 3.*a large quantity of +名词（不可数名词或可数名词）　构成的短语做主语时， 就近原则，　谓语动词要和ＯＦ　后面的名词的数保持一致，因为短语中ＯＦ后面的名词是中心词，而其他量词是修饰语 eg. A large quantity of food was on the table. A large quantity of shirts were on sale. *a large amount of + 不可数名词，的短语做主语时，谓语用单数． eg.A large number of damage was done in a very short time. 4.the amount of +　不可数名词　和　the quantity of +　可数名词复数／不可数名词　的短语做主语时，谓语用单数 eg. The amount of money is spent on the subject. 和其用法差不多的词有number a number of + 可数名词复数，谓语用复数． eg. A number of students have gone to the library. the number of + 可数名词复数，谓语用单数．
