科學家認為地球上的生命已存在了數(shù)億年。

hundredsofmillionsof數(shù)億……Wepaidhundredsofmillionsofdollarsintaxes.

我們交納了數(shù)億美元的稅金。Languagepoints數(shù)詞在表示模糊數(shù)目的短語中用復數(shù)形式，且后面要加上of。hundredsof數(shù)以百計的thousandsof數(shù)以千計的millionsof數(shù)以百萬計的billionsof數(shù)以億計的,數(shù)十億的百、千、百萬、十億如果和具體數(shù)字連用，百、千、百萬、十億須用單數(shù)形式。如：sixhundredtwothousandninemillionsevenbillion1.Itissaidthatthediseasehaskilledmorethan________peopleworldwide.A.twohundreds B.twohundreds’C.twohundred’s D.twohundred2.______ChinesearelookingforwaystolearnEnglishwell.A.Thousand B.Thousands C.ThousandofD.Thousandsof即學即練DD2.

地球是顆行星，它圍繞著太陽轉(zhuǎn)。此外還有七顆行星也圍繞著太陽轉(zhuǎn)。1)七顆行星指的是：水星（Mercury)、金星(Venus)、火星(Mars)、木星(Jupiter)、土星（Saturn)、天王星(Uranus)和海王星(Neptune)。2)goaround:

繞著……運轉(zhuǎn)

TheEarthgoesaroundtheSun.

地球繞著太陽轉(zhuǎn)。

Let'sgoaroundthetown,notthroughit.

我們繞過這城鎮(zhèn)吧，不要穿過去了。3)other/theother/others/another這幾個相類似的詞是學生容易弄混淆的，其實意思大相徑庭。other其它的（人或物）,后面經(jīng)常跟可數(shù)名詞復數(shù)形式；Wehaven’tfoundlifeonotherplanetsyet.我們還沒有在其它的星球上發(fā)現(xiàn)生命。（其他的星球不可能只有一個）theother（兩者中的）另一個,后面不可能跟復數(shù)形式；Hehastwodaughters.Oneisateacher,theotherisadoctor.他有兩個女兒，一個是老師，另一個是醫(yī)生。（有且只有兩個，兩者中的另一個）others其它的人或物（已經(jīng)包括在內(nèi)）,后面不能跟名詞，本身就含有名詞的含義；Somepeoplecamebycar,otherscameonfoot.有些人是坐汽車來的，其他人是走著來的。（others后面不能再加名詞）another（三者以上中的，或不知道數(shù)量的）另一個,后面也不可跟復數(shù)形式。Wouldyoulikeanothercupoftea?你要再來有一杯茶嗎？（泛指再來一杯）4)alsoadv.也，同樣；而且（不與否定式動詞連用）ShespeaksFrenchandGermanandalsoalittleRussian.她會說法語、德語，還會說一點兒俄語。Heisyoungandgood-looking,andalsoveryrich.他又年輕又漂亮，而且還很富有。IteachfivedaysaweekandIalsoteacheveningclasses.我每星期教五天，而且還教晚上的課。比較：also/too/aswellalso,too,aswell都指句中有關詞語與前面提到的事物相結合或相一致，這三個詞語的雅俗程度和在句中的位置有所不同。

also含較莊重色彩，通常用于主要動詞之前（但若主要動詞為be，則放于其后）e.g.I’vemetJaneandI’vealsomethermother.我已見到簡，我也見到了她的母親。Shewasrich,andshewasalsoselfish.她很富，她也很自私。too和aswell比較通俗，通常用于從句的句尾。e.g.I’vereadthebookandI’veseenthefilmaswell/too.我看過這本書，也看過這部電影。3.Noneofthemhasanenvironmentlikethatoftheearth…

沒有一顆行星擁有與地球一樣的環(huán)境……none

表示（三個以上）一個也沒有。意為“沒有一個人/東西”，none作主語時，謂語的單復數(shù)形式要根據(jù)實際情況來定。如：NoneofthemhasbeentoBeijing.他們中沒有一個人到過北京。（none指代可數(shù)名詞，強調(diào)單一性，謂語用單數(shù)形式）Noneofthemwereawareofthedanger.他們都沒有意識到危險。（none指代可數(shù)名詞，強調(diào)整體性，謂語用復數(shù)形式）Noneofthemoneyishis.這些錢沒有他的份兒。（none指代不可數(shù)名詞，謂語動詞用單數(shù)形式）4....andoursolarsystemisasmallpartofamuchlargergroupofstarsandplanets,calledtheGalaxyortheMilkyWay.……我們的太陽系只是一個由恒星和行星組成的星系的一小部分，這個星系比太陽系大得多，稱作銀河系或銀河。

這里的theGalaxy專指“銀河系”，也可以稱作theMilkyWay。而galaxy則泛指“星系”。例如：Scientistshavediscoveredadistantgalaxy.科學家發(fā)現(xiàn)了一個遙遠的星系。本句中calledtheGalaxyortheMilkyWay為過去分詞短語做定語，修飾amuchlargergroupofstarsandplanets。類似的例子還有：Theyhaveatwo-year-oldsoncalledMike.他們有一個兩歲的兒子叫邁克。5.However,nospaceshiphastravelledfarenoughtoreachotherstarsinourGalaxy.然而，還沒有任何航天器能到達銀河系里的其他恒星。形容詞/副詞+enoughtodo表示“到達……程度，會發(fā)生某結果”。Heisoldenoughtogotoschool.他到上學的年齡了。Hegotupearlyenoughtocatchthefirstbus.他起得很早，趕上了首班車。6....withsomanystarsintheuniverse,arewealone,oristherelifeoutthereinspace?……宇宙中有這么多星球，我們是孤獨的嗎，抑或太空中還有其他生命存在呢？

這里withsomanystarsintheuniverse是介詞短語，在句中作狀語。with+名詞+介詞短語,在句中做狀語，表示伴隨情況。Withsomanythingstodo,wehavenotimetoplay.要做的事情這么多，我們都沒時間玩兒了。aloneadj.孤單的，孤獨的在句中作形容詞，不作定語只做表語，也可作副詞。意思是“獨自地”。Idon’tlikegoingoutaloneafterdark.我不喜歡天黑后獨自外出。比較：alone/lonelyalone表示獨自一人；lonely表示心靈上的孤單。AlthoughI’malone,Idon’tfeellonely.雖然我獨自一人，但是我不感到孤單。單項選擇1.Intheworld___peoplelikewatchingTV.A.millionsofB.twomillionsC.twomillionofD.twomillionof
