要看具體情況：表示準(zhǔn)確數(shù)值時(shí)候,不要,比如300,500.表示大概的數(shù)量時(shí)候就要復(fù)數(shù),但前面不加具體的數(shù)字,參考下面：
hundred

> hundred n (after a or one,a number or an indication of quantity 用於a、 one、 數(shù)詞或含有數(shù)量意義的詞之后) the number 100 *100; 一百:How many hundreds are there in a thousand?一千里有多少個(gè)一百?* Her coat cost hundreds (of pounds).她的大衣值好幾百（鎊）.* There are hundreds (of people) (ie very many) who need new housing.有許許多多人需要新的住房.* The cake was decorated with a large (one) hundred.這塊蛋糕上面裝飾著一個(gè)很大的‘（一）百’字樣.
