【句型精析】
1.Treescanstopthewindfromblowingtheearthaway.树木可以防止风吹走尘土。
(1)blowaway是动副词组,意为“吹走”,名词可以放在blowaway的后面或中间,代词必须放在blow和away的中间。
如:
AstrongwindblewawayMr.Green’ssheepnearly.一场大风险些把格林先生的羊吹走。
(2)stop…fromdoingsth.意为“阻止……做某事”,相当于keep/prevent…fromdoingsth.如:
Thetreescanstopthewindfromblowingawaytheearth.树能阻止大风吹走泥土。
词组blowaway和stop…fromdoingsth.的用法在中考中是常考点。
blowinto意为“吹进”如:
Don’tblowintotheplasticbag.不要往塑料袋里吹气。
根据汉语意思完成英语句子,每空一词。
刚才一股强风把吉姆的帽子吹走了。
Astrongwind________________Jim’shatjustnow.
答案:
blewaway
思路分析:
blowaway意为“吹走”,和justnow连用,应该用一般过去时,因此填blewaway。
Weshould_________people_________throwinglittersabout.
A.protect;
fromB.protect;
forC.stop;
forD.stop;
from
D
本题考查词组stopsb.fromdoingsth.“阻止某人做某事”,根据句意“我们应该阻止人们乱扔垃圾。
”故选D。
2.Worstofall,someofthemarequiterude…最糟糕的是,他们中有些人很粗鲁……
worst意为“最差的,最糟的”,是bad的最高级,worstofall“最糟的是”,用来引出最坏的事情。
Itwastheworstwinterfor50years.这是50年来最糟的一个冬天。
Worstofall,Ilostmypackage.最糟的是,我把包裹丢了。
形容词bad的最高级worst和词组worstofall的用法在中考中是常考点。
what’sworse意为“更糟糕的是”,表示两种并列的坏的情况,且后面一个更严重。
Itbegantorainsuddenly,whatwasworse,wedidn’ttakeanyumbrella.天突然开始下雨了,更糟糕的是,我们没有带雨伞。
Ofallthestudents,Joan’shomeworkisthe_________.Herteacherisveryangry.
A.betterB.bestC.worseD.worst
三者及以上比较应用最高级。
由“她的老师很生气”可知“琼的作业是最差的”。
故选D。
3.Somethingswehavedoneareverygoodfortheearthwhileothersarebad.我们所做的事情一些对地球有益,然而另一些却对地球有负面影响。
while这里用作并列连词,意为“而,却”,表示对照关系。
Hersisterlikesreadingwhileshelikessinging.她妹妹喜欢看书,而她喜欢唱歌。
Theyallwentoutwhileshestayedathome.他们都出去了,她却留在家里。
while作并列连词和从属连词的用法在中考中是常考点。
(1)while还可用作从属连词,意为“在……时”,常用来引导含有延续性动词的时间状语从句,表示一个动作在进行的同时,另一个动作也在发生。
Whilelwasdoingmyhomework,mymotherwascooking.我做作业时,妈妈正在做饭。
(2)while还可用作名词,意为“一会儿,一段时间”。
Wearegoingawayforawhile.我们将离开一会儿。
Tomisverygoodatscience_________hisbrotherJimmyknowsnothingaboutit.
A.ifB.whenC.whileD.because
C
此处while用作连词表示对比,意为“然而”,故选C。
虽然地球表面近四分之三被水覆盖,我们仍旧缺乏饮用水。
(1)nearly是副词,意为“几乎,将近”。
Thebuswasnearlyfull.公交车几乎满座了。
Ittooknearlytwohourstogetthere.花了近两个小时才到那里。
(2)becoveredwith被……覆盖。
Thegroundiscoveredwithsnow.地面上覆盖着积雪。
词组becoveredwith在中考中是常考点。
(1)cover…with…用……覆盖……如:
Theycoveredtheboywithablanket.他们给男孩盖上一条毛毯。
(2)fromcovertocover从头到尾如:
Healwaysreadsnewspaperfromcovertocover.他总是把报纸从头到尾阅读一遍。
Afteraheavysnow,thewholemountain_________whitesnow.
A.isshortofB.isfullofC.iscoveredwithD.isfilledwith
C
becoveredwith意为“被……覆盖”,符合语境,故选C。
5.Weshoulddoeverythingwecantoprotecttheenvironment.我们应该尽一切努力保护环境。
(1)everything是不定代词,意为“每件事物,一切”,不特指哪一件事物。
everything作主语时,谓语用单数。
Everythinggoeswell.一切安好。
/一切顺利。
(2)修饰everything的定语从句wecan后省略了谓语动词do。
不指明替代任何特定名词或形容词的代词叫做不定代词。
大多数不定代词在句中可以作主语、表语、宾语、同位语和定语。
(1)复合不定代词作主语时,谓语动词用单数形式。
Somethingiswrongwiththecomputer.电脑坏了。
(2)形容词修饰不定代词时应该放在不定代词之后。
Thereissomethingdeliciousonthetable.桌子上有好吃的。
(3)some-/any-复合不定代词的用法与some/any用法基本一致。

否定句和疑问句中通常用any-。
Wouldyoulikesomethingtoeat?
你要点儿吃的东西吗?
Idon’tknowanythingaboutit.我什么也不知道。
Iheardsomebodysingingintheclassroom.我听见教室里有人在唱歌。
some,any,no和every还可以与where连用,构成表示地点的副词,即:
somewhere,anywhere,nowhere,everywhere。
其用法与some/any用法基本一致。
I’veseenhimsomewherebefore.我以前在哪儿见过他。
Therewasnowhereformetosit.我无处可坐。
—Mum,I’vegot__________importanttotellyou.
—What’sup?
