科學(xué)家們認(rèn)為地球上的生命已經(jīng)有上億年的歷史。hundred前加基數(shù)詞，表示“一百、二百、三百……”，hundred要用單數(shù)形式；hundred與of連用表示“數(shù)百”時，hundred要用復(fù)數(shù)形式，即hundredsof。19精選課件例如：Thereareeighthundredstudentsinourschool.Therearehundredsofpeopleinthepark.Weplanted_____treeslastyear.A.hundredsofB.hundredofC.fivehundredsD.fivehundredofthousand,million,billion和hundred的用法相同。Practise20精選課件2.Withsomanystarsintheuniverse,arewealone,oristherelifeoutthereinspace?

宇宙中有這么多星球，我們是孤獨(dú)的嗎？抑或太空中還有其他生命存在呢？

Withsomanythingstodo,wehavenotimetoplay.

要做的事情這么多，我們都沒時間玩了。withsomanystarsintheuniverse是介詞短語，作伴隨狀語。類似的例子還有：21精選課件Thewomanstoodtherewithherhandsinthepockets.那個女士站在那里，手插在口袋里。Practise—Whydoyoualwayssleep______?—BecauseI’mafraidofthedark.A.byyourselfB.withthedooropenC.withthewindowopenD.withthelighton22精選課件3.Noneofthemhasanenvironmentlikethatoftheearth,soscientistsdonotthinktheywillfindlifeonthem.

他們中沒有一個有像地球這樣的環(huán)境，因此科學(xué)家們認(rèn)為在他們上面找不到生命。

noneof…

表示（三個以上）一個也沒有。做主語時，謂語動詞可用單數(shù)或復(fù)數(shù)。e.g.我們中沒一個人去過火星。

Noneofushas/havebeentoMars.23精選課件注意：none與noone（nobody）的區(qū)別：none既可指人也可指物，通常與表范圍的of短語連用；noone(=nobody)只能指人，不能與of短語連用。如：Noneofushas/havebeentoSanya.我們都沒去過三亞。

(2)none與數(shù)量有關(guān)，可回答howmany問句，表示“一個也沒有”；而noone表示“什么人也沒有”，可回答who問句。如：-Whoareyouspeakingto?-_________.-Howmanystudentsarethereintheroom?-_________.NooneNone24精選課件that是指示代詞。為避免重復(fù)，可用that或those來代替前面已提到過的人或事物；

Theairinthecountrysideisfresherthan_________inthecity.

Thestreetsinthecityarewiderandthebuildingsaretallerthan________inthecounty.Theenvironmentismuchcleanerthan________inthecity.

ThepopulationofShanghaiismuchlargerthan______ofNanning.thatthosethatthat25精選課件4.However,nospaceshiphastraveledfarenoughtoreachotherstarsinourGalaxy.然而，沒有一個航天器去到足以到達(dá)我們銀河系其他恒星那么遠(yuǎn)的地方。

Wehave___________________________.(2)他跑得夠快，很快追上了我們。

Heran________________catchupwithussoon.(3)他年齡不夠大，照顧不了自己。
