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(shí)，hundred要用復(fù)數(shù)形式，即hundredsof。hundredsofmillionsof表示“數(shù)億，上億”。例如：Thereareeighthundredstudentsinourschool.Therearehundredsofpeopleinthepark.Weplanted_____treeslastyear.A.hundredsofB.hundredofC.fivehundredsD.fivehundredofthousand,million,billion和hundred的用法相同。Practise2.Noneofthemhasanenvironmentlikethatoftheearth…

沒有一顆擁有和地球一樣的環(huán)境……Whyhasnoonecommunicatedwithus?

為什么沒有人和我們聯(lián)系呢？none指三個(gè)或三個(gè)以上的人或物中“沒有一個(gè)”，其后常接“of+名詞/代詞”，后面動(dòng)詞單復(fù)數(shù)形式均可。noone表示“沒有人”，作主語時(shí)，謂語動(dòng)詞常用單數(shù)形式。Werangseveraltimes,butnooneanswered.我們按了幾次鈴，但沒有人來開門。Noneofushas/havebeentoSanya.我們都沒去過三亞?！狪’mhungry.Isthereanybreadinthefridge?—_____,butwehavecakes.Wouldyouliketohaveone?A.SomeB.MuchC.NoneD.NothingPractise3.However,nospaceshiphastravelled

farenoughtoreachotherstarsinourGalaxy.

然而，還沒有任何航天器能到達(dá)銀河系里的其他恒星。Heisnotoldenoughtojointhearmy.他年齡太小，不能參軍。Wehaveenoughtimetofinishthework.我們有充足的時(shí)間完成這項(xiàng)工作。enough作副詞，修飾形容詞或副詞時(shí)放在被修飾詞后面；enough作形容詞，修飾名詞時(shí)常放在被修飾詞之前。如：4.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(shí)間玩了。這里withsomanystarsintheuniverse是介詞短語，在句中作狀語。類似的例子還有：Thewomanstoodtherewithherhandsinthepockets.那個(gè)女士站在那里，手插在口袋里。Practise—Whydoyoualwayssleep______?—BecauseI’mafraidofthedark.A.byyourselfB.withthedooropenC.withthewindowopenD.withthelightonWritingWhathavethescientistsjustreceived?
