用法辨析
- quantity的基本意思是“數(shù)量”,是正式用語(yǔ)。作與質(zhì)量相對(duì)而言的“數(shù)量”解時(shí)是不可數(shù)名詞,指事物的“量”或“總數(shù)量”時(shí)是可數(shù)名詞。quantity強(qiáng)調(diào)大批計(jì)量,含有準(zhǔn)確測(cè)量的意味。
- quantity不能用much, less等表示“多少”意義的詞修飾,可用large, great, small等表示“大小”意義的詞修飾。
- a (large〔great〕) quantity of或quantities of的意思是“大量”,其后均可跟不可數(shù)名詞或復(fù)數(shù)名詞。在句中作主語(yǔ)時(shí), a quantity of接不可數(shù)名詞時(shí),謂語(yǔ)動(dòng)詞用單數(shù)形式,接可數(shù)名詞復(fù)數(shù)時(shí),謂語(yǔ)動(dòng)詞用復(fù)數(shù)形式; quantities of修飾不可數(shù)名詞或可數(shù)名詞復(fù)數(shù)時(shí),謂語(yǔ)動(dòng)詞都用復(fù)數(shù)形式。
- quantity既可用于可數(shù)名詞也可用于不可數(shù)名詞,如a quantity of flowers和a quantity of water。
n. (名詞)
