词语用法

1. quantity既可用于可数名词也可用于不可数名词，如a quantity of flowers和a quantity of water。

n. (名词)

1. quantity的基本意思是“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。quantity强调大批计量,含有准确测量的意味。
2. quantity不能用much, less等表示“多少”意义的词修饰,可用large, great, small等表示“大小”意义的词修饰。
3. a (large〔great〕) quantity of或quantities of的意思是“大量”,其后均可跟不可数名词或复数名词。在句中作主语时, a quantity of接不可数名词时,谓语动词用单数形式,接可数名词复数时,谓语动词用复数形式; quantities of修饰不可数名词或可数名词复数时,谓语动词都用复数形式。

词义辨析

n. (名词)

quantity, aggregate, amount, number, sum, total, whole

• 这组词的共同意思是“总数、总合”。其区别是：
• aggregate指把数目的各个部分加在一起；amount指累积的结果；number指数字或东西相加所得的总数；sum指最后的总结果，表示截至现在的总数, 还有增加的可能；total和whole都指合计的结果的全体，total常指大的数量，whole也含有各部分总和的意味。quantity主要表示物质的量。
• adj.
• ［' ɡrIɡət］

quantity，amount，number，sum

• 这些名词均有“总数、总量”之意。
• quantity书面用词，指事物的总量和总数量，侧重大批计量，含准确测量的意味。
• amount普通用词，与quantity近义，但强调整体，指把所有数量、重量及度量归并在一起得出的总数。
• number普通用词，指人或物的数目，强调数的概念。
• sum普通用词，指简单加算的结果。
