科学家们认为地球上的生命已经有上亿年的历史。hundred前加基数词，表示“一百、二百、三百……”，hundred要用单数形式；hundred与of连用表示“数百”时，hundred要用复数形式，即hundredsof。19精选课件例如：Thereareeighthundredstudentsinourschool.Therearehundredsofpeopleinthepark.Weplanted_____treeslastyear.A.hundredsofB.hundredofC.fivehundredsD.fivehundredofthousand,million,billion和hundred的用法相同。Practise20精选课件2.Withsomanystarsintheuniverse,arewealone,oristherelifeoutthereinspace?

宇宙中有这么多星球，我们是孤独的吗？抑或太空中还有其他生命存在呢？

Withsomanythingstodo,wehavenotimetoplay.

要做的事情这么多，我们都没时间玩了。withsomanystarsintheuniverse是介词短语，作伴随状语。类似的例子还有：21精选课件Thewomanstoodtherewithherhandsinthepockets.那个女士站在那里，手插在口袋里。Practise—Whydoyoualwayssleep______?—BecauseI’mafraidofthedark.A.byyourselfB.withthedooropenC.withthewindowopenD.withthelighton22精选课件3.Noneofthemhasanenvironmentlikethatoftheearth,soscientistsdonotthinktheywillfindlifeonthem.

他们中没有一个有像地球这样的环境，因此科学家们认为在他们上面找不到生命。

noneof…

表示（三个以上）一个也没有。做主语时，谓语动词可用单数或复数。e.g.我们中没一个人去过火星。

Noneofushas/havebeentoMars.23精选课件注意：none与noone（nobody）的区别：none既可指人也可指物，通常与表范围的of短语连用；noone(=nobody)只能指人，不能与of短语连用。如：Noneofushas/havebeentoSanya.我们都没去过三亚。

(2)none与数量有关，可回答howmany问句，表示“一个也没有”；而noone表示“什么人也没有”，可回答who问句。如：-Whoareyouspeakingto?-_________.-Howmanystudentsarethereintheroom?-_________.NooneNone24精选课件that是指示代词。为避免重复，可用that或those来代替前面已提到过的人或事物；

Theairinthecountrysideisfresherthan_________inthecity.
