◎用法总结:threeeighths八分之三。英语中分数的表达方法是:分子在前,分母在后;分子用基数词,分母用序数词;当分子大于1时,分母(序数词)后加s。如:六分之一onesixth;十分之七seventenths另外,二分之一还可以用half表达;四分之一还可以用onequarter表达;四分之三还可以表达为threequarters等。对点自测根据汉语提示填写单词。(三分之二)oftheclassareplantingtreesbytheriver.

【答案】Twothirds[命题点二]paredwithlifeontheEarth,lifeonMarswouldbebetterinsomeways.和地球上的生活相比,火星上的生活在某些方面会更好。

◎用法总结:1pare和逻辑主语life之间是被动关系,所以pare要用其过去分词形式。2pare...with...把……与……相比较;pare...to...把……比作……。二者意思截然不同,使用时注意区别。如:Ifyouparethispairofshoeswiththatpair,youwillknowwhichisbetter.如果你把这双鞋和那一双比较一下,你就会明白哪双更好。Weoftenparelifetoasong,and
