How much does twenty minus five equal? ⑵Twenty minus five is fifteen. How much is twenty minus five? 英语分数、小数及百分数的表达 1.表达形式

⑴分数

①基本规则:子基母序(即:分子用基数词,分母用序数词) 1/3 one third 1/8 one eighth 1/12 one twelfth ②当分子大于1时,分母要加s变成复数。

2/3 two thirds 3/8 three eighths 5/12 five twelfths ③特殊的表达:

1/4 可以表示为 one fourth 或者 a quarter

3/4 可以表示为 three fourth 或者 three quarters 1/2 a half ⑵.小数

小数点前后的数均按基数词来读,小数点读成point 小数点后的数字逐位读出。

3.1415926 three point one four one five nine two six 0.463 zero point four six three ⑶.百分数

汉语中先读百分号,再读数字;英语中恰恰相反:先念出数字,再加上百分号percent

80% eighty percent

99.5% ninety-nine point five percent


2.由分数、小数或百分数构成主语时,其后的谓语跟分数、小数或百分数的单复并无关系,而是由这些数后的名词的情况来决定。

⑴当所修饰的名词是不可数名词或可数名词的单数时,谓语用单数。 Three quarters of the earth’s surface is water. ⑵当所修饰的名词是可数名词的复数时,谓语用复数。
