4.ThegravityonMarsisonlyaboutthree-eighthsofthatonEarth.Three-eighths八分之三分数在英语中通常是借助于基数词和序数词来共同表达的。其中基数词表示分子，序数词表示分母。如：one-tenth十分之一athird三分之一注意：分子除用one外，也可用a；twothirds三分之二fourfifths五分之四但是，1/2不能说a(one)second,而要说a(one)half。1/4和3/4可以说a(one)fourth和threefourths,但常用aquarter和threequarters表示。如果分子大于1，分母要用复数形式。如：选择题。About______ofthestudentsarefromforeigncountries.(2011山东东营)A.threefourB.threefourthC.thirdfourthD.threefourths翻译句子。我们班五分之三是女生。_____________thestudentsinmyclass________girls.practiceThree-fifthsofare5.ComparedwithlifeonEarth,lifeonMarswillbebetterinmanyways.compare:examinepeopleorthingstoseehowtheyaresimilarandhowtheyaredifferent(v.比较，对比)Wecarefullycomparedthefirstreportwiththesecond.我们仔细的对第一份报告和第二份报告进行了对比。comparewith把……相比较
