◎用法總結:threeeighths八分之三。英語中分數(shù)的表達方法是:分子在前,分母在后;分子用基數(shù)詞,分母用序數(shù)詞;當分子大于1時,分母(序數(shù)詞)后加s。如:六分之一onesixth;十分之七seventenths另外,二分之一還可以用half表達;四分之一還可以用onequarter表達;四分之三還可以表達為threequarters等。對點自測根據(jù)漢語提示填寫單詞。(三分之二)oftheclassareplantingtreesbytheriver.

【答案】Twothirds[命題點二]paredwithlifeontheEarth,lifeonMarswouldbebetterinsomeways.和地球上的生活相比,火星上的生活在某些方面會更好。

◎用法總結:1pare和邏輯主語life之間是被動關系,所以pare要用其過去分詞形式。2pare...with...把……與……相比較;pare...to...把……比作……。二者意思截然不同,使用時注意區(qū)別。如:Ifyouparethispairofshoeswiththatpair,youwillknowwhichisbetter.如果你把這雙鞋和那一雙比較一下,你就會明白哪雙更好。Weoftenparelifetoasong,and
