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。hundredsofmillionsof表示“数亿，上亿”。例如：Thereareeighthundredstudentsinourschool.Therearehundredsofpeopleinthepark.Weplanted_____treeslastyear.A.hundredsofB.hundredofC.fivehundredsD.fivehundredofthousand,million,billion和hundred的用法相同。Practise2.Noneofthemhasanenvironmentlikethatoftheearth…

没有一颗拥有和地球一样的环境……Whyhasnoonecommunicatedwithus?

为什么没有人和我们联系呢？none指三个或三个以上的人或物中“没有一个”，其后常接“of+名词/代词”，后面动词单复数形式均可。noone表示“没有人”，作主语时，谓语动词常用单数形式。Werangseveraltimes,butnooneanswered.我们按了几次铃，但没有人来开门。Noneofushas/havebeentoSanya.我们都没去过三亚。—I’mhungry.Isthereanybreadinthefridge?—_____,butwehavecakes.Wouldyouliketohaveone?A.SomeB.MuchC.NoneD.NothingPractise3.However,nospaceshiphastravelled

然而，还没有任何航天器能到达银河系里的其他恒星。Heisnotoldenoughtojointhearmy.他年龄太小，不能参军。Wehaveenoughtimetofinishthework.我们有充足的时间完成这项工作。enough作副词，修饰形容词或副词时放在被修饰词后面；enough作形容词，修饰名词时常放在被修饰词之前。如：4.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。这里withsomanystarsintheuniverse是介词短语，在句中作状语。类似的例子还有：Thewomanstoodtherewithherhandsinthepockets.那个女士站在那里，手插在口袋里。Practise—Whydoyoualwayssleep______?—BecauseI’mafraidofthedark.A.byyourselfB.withthedooropenC.withthewindowopenD.withthelightonWritingWhathavethescientistsjustreceived?
