every与each的区别every用来表整体，each用来表个别，each最低需是两，every最低需是三。every作主用单数，each可单也可复，作主、定用单数，其他情况用复数。

3．Bookswillonlybeoncomputers，notonpaper.

书只会在电脑上，而不会在纸上。

papern.“纸，纸张”，是不可数名词。表示“一张纸”用apieceofpaper，“两张纸”用twopiecesofpaper。

e.g.Thereisapieceofpaperonthetable.桌子上有一张纸。

papern.“试卷”，作可数名词，有复数形式。

e.g.Ilostahistorypaper.

我丢了一份历史试卷。【例题】Theteachermarked(批分数)theexam______andwrotethestudents'gradesonapieceof______.A．papers；paper

B．paper；papersC．paper；paper

D．papers；papers解析:根据前半句的marked可知第一空填papers，意为“试卷”，是可数名词；第二空填paper，构成固定搭配apieceofpaper“一张纸”。答案

A句意 老师批阅了试卷并把学生们的分数写在了一张纸上。4.Willpeopleusemoneyin100years?

in100years意为“在100年以后”，其中in为介词，其后跟一段时间表示“......之后”，通常用于一般将来时，对其提问时须用howsoon（多久）。---Howsoonwillyourmotherfinishcookingdinner?---Inanhour.辨析：in与afterin和after都表示“在......之后”，它们的用法见下表：

e.g.Hewillbebackintwodays.HestartedonSundayandarrivedinBeijingafterthreedays.

5．Therewillbefewerpeople.将有更少的人。本句是含有therebe句型的一般将来时的简单句。

结构为：Therewillbe＋主语＋其他。其否定形式是在will后加not；疑问句形式是把will提到there前。简略肯定回答：Yes，therewill.简略否定回答：No，therewon't.

e.g.Therewillnotbeenoughroomforpeopletolivein.

将没有足够的给人住的空间。

e.g.Willtherebefeweranimalsintheworld?

世界上将有更少的动物吗？

feweradj.(few的比较级)较少的；更少的，修饰可数名词的复数形式。

e.g.Ihavefewerfriends.我有更少的朋友。fewer，less和more(1)fewer同上。e.g.MyfriendhasfewerapplesthanI.

我朋友比我的苹果少。(2)less较少的；更少的，little的比较级，修饰不可数名词。e.g.Ihavelessmoneyinmybag.

我包里的钱更少了。(3)more更多的，many和much的比较级，可修饰可数名词，也可修饰不可数名词。e.g.Thereismorewaterinthebottle.

我们有更多的挑战。【例1】—Willthere______anypapermoneyin100years?—No，______.

A．have；therewon't B．be；therewon't

C．have；theywon't D．be；theywon't

点拨：根据问句中的there可知是考查therebe句型；其简略否定答语也用there。答案：B【例2】We'lltryourbesttodotheworkwith______moneyand______people.

A．few；little B．afew；alittle

C．less；fewer D．fewer；less

点拨：money是不可数名词，要用little及其有关的词或短语修饰；people是复数形式，要用few及其有关的词或短语修饰。句意为“我们将尽力用更少的资金、更少的人去完成这项工作”。答案：C【例3】根据汉语意思完成下句我想要更多水、更少的食物。Iwouldlike______waterand______food.

答案：more；less6.Therewillbe(more/less/fewer)pollution.

D．pollute；polluted

点拨：浏览题干可知，第一空在句中作主语，故用名词pollution；第二空在系动词are后，故用形容词polluted；pollute是动词。句意为“现在污染很严重。一些河流、湖泊被污染了”。

答案：C7.What'syourpredictionaboutthefuture?future名词，意为“将来；未来”。常用短语：inthefuture意为“在将来，以后”，特指将来的某一时刻。e.g.Whoknowswhatwillhappeninthefuture?拓展：infuture指从今以后的全部将来，相当于fromnowon。e.g.Infutureyou'dbettergethispermissionfirst.8.Idon'tthinkso.

Idon'tthinkso.是英语口语中常用的一个短句，表示否定对方的意见或观点，意为“我不这样认为”，其肯定形式为Ithinkso.。e.g.---Lookattheclouds.Itwillberainysoon.---Idon'tthinkso.Ithinkitwillbesunnysoon.拓展：类似的结构还有Ihopeso.（我希望是这样的）
