amount、number、quantity的用法区别为:使用时意思不同、使用场合不同、侧重点不同。

一、使用时意思不同

1.amount解析:金额;数量;数额

2.number解析:数字;数;数量;编号;序数;(电话、传真等的)号码

3.quantity解析:数量;数额;数目;量;大量;大批;众多;大宗

二、使用场合不同

1.amount解析:amount用作动词的基本意思是“合计,共计”,引申可指“等同,接近”。

2.number解析:基本意思是“数字”,引申可作“编号,电话号码,房间号码”解,是可数名词。number也可作“数目,数量”解,其后常与介词of连用,引申可表示语法上名词或动词的“数”或“数词”。

3.quantity解析:基本意思是“数量”,是正式用语。作与质量相对而言的“数量”解时是不可数名词,指事物的“量”或“总数量”时是可数名词。

三、侧重点不同

1.amount解析:amount是不及物动词,常与介词to连用。

2.number解析:作及物动词,也可用作不及物动词。用作及物动词时接名词或代词作宾语。

一、amount的用法详解 1. amount用作名词 其意为“数量”、“金额”等,通常用于 a (great, large) amount of 这类结构,其后通常接不可数名词。如:
He made a large amount of money. 他赚了大量的钱。
They have to process a large amount of data. 他们得处理大量数据。 I had not expected such an amount of praise. 我没料到受到这么多赞扬。 A large amount of damage was done in a short time. 短期内造成大量损害。 I had not expected such an amount of praise. 我没料想受到这样多的赞扬。 He must memorize large amounts of material. 他必须背熟大量材料。 注意:这类结构用作主语,其谓语的数取决于 amount 的数。如: 在这座桥上花了大量资金。
正: A large amount of money was spent on the bridge. 正: Large amounts of money were spent on the bridge.
比较:在 a great number of 之后通常接可数名词(用复数)。如:
2. amount用作动词
用作动词时意为“合计”、“等于”、“意味着”,通常是不及物动词,其后常接介词 to。如: Building cost amounts to six million dollars. 建筑费用达600 万元。 Her reply amounts to a refusal. 她的回答等于拒绝。
注意:由于其后接的to为介词,所以后接动词时,该动词要用动名词。如: 这等于是欺骗老师。(from www.yywords.com) 误:This amounts to cheat the teacher. 正:This amounts to cheating the teacher. 析:amount 用作动词,表示“等于”,是不及物动词,其后接的to 为介词。 二、a great/good many 非常多,许多(形容词)
The young couple has travelled a great many cities since they got married. A great many college students were sent to the West to help the children there.
Helen has a great many friends indeed, but she does not think she has any she can confide in.
The city was even equipped with a drainage system, for a great many clay pipes were found beneath the narrow streets.
He has extracted a great many examples from the grammar book. 比较:
1. many a... 许多(后接单数动词)
Many a teacher has come to the exhibition.
Many a woman has great influence on her husband. He beguiled us with many a tale of adventure.
2. a lot, lots of, a number of 与 a great many / a good many 意义相同。
quantity 用法结论:
1.a quantity of后既可接复数可数名词,亦可接不可数名词。在它们分别和其后的名词构成短语作主语时,其谓语动词通常看of后名词的具体情况而采用单数或复数形式。如果是接不可数名词,则谓语用单数形式,如果是接复数可数名词,则谓语通常要采用复数形式 2.quantities of后既可接复数可数名词,亦可接不可数名词,后面的谓语都用复数形式。 1)Besides, a large quantity of mail bags were found. 2)and a small quantity of dangerous drugs were seized.
3)A quantity of fake certificates and official stamps were also seized.
