1 分數(shù)表示法是:
分子→基數(shù)詞
分母→序數(shù)詞
如果分子是1,分母就用單數(shù),如果分子是2或2以上,分母就用復數(shù)。
二分之一:a half或one half (二分之一不能說a second或one second )
三分之一:a third或one-third
四分之一:a quarter或one-quarter
五分之一:a fifth或one-fifth
三分之二:two-thirds
四分之三:three-fourths或three quarters
五分之三:three-fifths
八分之五:five-eighths
2 分數(shù)詞用作主語時,謂語動詞用單數(shù)還是復數(shù),要根據(jù)分數(shù)詞本身代表的是單數(shù)還是復數(shù)而定。
