      分数表达:

      二分之一: half a / an 或a half. 如:

      half an hour = a half hour半小时 It’s half past seven.(省略冠词)

      以下情况中,分子(基数词)若超过一,分母(序数词)需加s:

      三分之一: a / one third 三分之二: two thirds

      四分之一: a / one fourth 或a / one quarter

      四分之三: three fourths或three quarters.

      五分之一: a / one fifth 五分之二: two fifths 其它类推。

      若分数所在of短语作主语,谓语依of后的名词而定:

      A third of the boys have passed the test. A third of the work has been over.

      Two fifths of the students are on time. Two fifths of the 初二 land is polluted.

      (of后是可数名词复数时,谓语用复数;of后是不可数名词时,谓语用单数。)
