分数、小数和百分比的读法;分数中分子用基数词表示、分母用序数词表示.先读分子,后读分母.当分子大于1时,分母要加“s”.例如 1/2读作:a/one half(口语中更倾向于用“a”代替“one”) 1/3读作:a/one third 1/8读作:an/one eighth 1/4读作:a/one quarter(fourth) 2/3读作:two thirds 1又5/9读作one and five ninths 比较复杂的分数常常用over这个词表示.如: 317/509读作:three hundred and seventeen over five hundred and nine 3/4hour,7/lOmile则说three quarters of an hour(三刻钟),seven tenths of a mile(十分之七英里).
分数表示法1. 分数是由基数词和序数词一起来表示的。基数词作分子,序数词作分母,除了分子是“1”以外,其它情况下序数词都要用复数形式。3/4 three fourths或 three quarters1/3 one third或a third24/25 twenty-four twenty-fifths3 1/4 three and one fourth或 three and one quarter1/2 a half1/4 one quarter或a quarter1 1/2 one and a half1 1/4 one and a quarter2. 当分数后面接名词时,如果分数表示的值大于1,名词用复数;小于1,名词用单数。1 1/2 hours 一个半小时(读作 one and a half hours)2 3/4 meters 二又四分之三米(读作two and three-fourths meters)4/5 meter 五分之四米5/6 inch 六分之五英寸3. 表示“n次方”的说法:指数用序数词,底数用基数词。10的7次方 the seventh power of ten(ten to the seventh power)6的10次方 the tenth power of six(six to the tenth power)
