    81 hundreds of还是hundred of——数词的概指与确指怎样表示

    1 hundred (百),thousand (千) 和million (百万) 这几个词,前面有具体数词,表示确指数目 时,要用单数形式,后面也不可用of 短语;前面没有具体数词,表示概指 时,要用复数形式,后面加of 短语,结构为:

    确指数词+hundred/ thousand/ million+被修饰的名词→……百/千/百万个……

    hundreds/ thousands/ millions of+被修饰的名词→几百个/几千个/几百万个……

    She has five hundred books. 她有500本书 。(确指 )

    She has hundreds of books. 她有好几百本书 。(泛指 )

    Three thousand people were present at the meeting. 3 000人参加了那次会议 。

    Thousands of people died in the war. 成千上万的人在那场战争中死去了 。

    Four million pencils were sold out.(正) 四百万支铅笔销售一空 。

    Millions of pencils were sold out.(正) 数百万支铅笔销售一空 。

    2 “一百”可以说a hundred 或one hundred ,一般情况下用a hundred ,表示连贯的计数或比较时则要用one hundred 。
