4、o,shehasn't.2.BusinessmenareafraidofnewspapersandTVstations.生意人害怕报纸和电台。beafraidof意思是"害怕"。afraid是形容词，在句中只能作表语，后跟名词或动词的-ing形式（指自己不能决定而突然发生的事），及frightened的意思相同。beafraid后也可跟动词不定式表示"害怕做某事"即：beafraidtodosth.。另外，afraid后还可跟that引导的宾语从句，意思是"担心，恐怕"。例如：（1）Iamafraidofmice.我害怕老鼠。

11、business.ImakeofwhatEmmahavedoneforme,luckily,Imadefriendwithher.7.Themoretrees,thebetter的结构这里是"themore，themore"句型表述结构，它的意思是"越多越好；越，越"。例如：Startyourwork,thesooner,thebetter.开始工作吧，越快越好。ThemoreIthinkofit,thehappierIam.我越想越高兴：Theharderyouwork,thegreaterprogressyouwillmake.你越用功，进步就越大。

12、Thelongerwestayedthere,themorewelikethepeoplethere.我们在那里呆得越久，越喜欢那里的人民。注意：在"themore，themore"这个句型中，"the"不能省略。8needtodobetterinprotectingtheenvironment.需要在保护环境方面做得更好。dowellin在某方面干得好。dobetterin在某方面干得更好。在in后面加名词或动名词。例：Hedoeswellinplayingfootball他足球踢得很好。9延续性动词及非延续性动词延续性动词：表示动作能够持续发生一段时

15、例题解答及分析.词语练习：根据句意选择合适的词语填空。)_youhavelockedthedoor.youneedntworryaboutit.I_Ilockeditbeforeweleft.2)Dontworry!wellwatertheflowersassoonaswe_home.3)Imverymuch_theteacher.Im_theywontcometomyparty.4)Susan_thatshewouldhavechancetocometochinasomeday.解析：1)makesure;amsure（此句意思是：确定一下你是否锁门了。besure回答是：别操心了，我肯定锁

16、了。）2)arrive3)afraidthat（第一句话空后因为是一个名词，且意思是：害怕。afraidthat第二句话空后是一句话，所以用that来连接一个从句。）4)kepthoping（此句意思是：她一直希望有一天会有机会来中国。表示持续不断的动作或状态用keepdoing。）2.jimhasbeenatthefactory_twoyearsago.A.forB.sincec.beforeD.after解析：答案为B。本题主要考查时间状语及谓语的关系。for后跟时间段表示一段时间，since后跟时间的起点，表示一段时间，before表示在什么时间之前，after则表示在什么时间之后。本句

17、是完成时态，指自两年前以来如何，且两年前是个时间的（起）点，因此，此处应用since。3.mrSmithhastaughthere_tenyearsago.A.forB.beforec.sinceD.into解析：现在完成时态除表示动作已经完成外，还表示动作在过去已经开始，并一直延续到现在。常常和for或since所构成的时间状语连用。for后面的宾语表示的是一段时间，而since后面则是表示过去的某一时间点。since还可作连词引导时间状语从句，从句中的谓语动词常用一般过去时态，主句用完成时态。所以，根据题意本题答案为c。例如：（1）Ivebeenhereforovertwoyears我来这

18、儿两年多了。（2）Iveknownhimsincetenyearsago十年前我就认识他了。（3）Hehasworkedinthisfactorysincehecametochina他自从来到中国就一直在那家工厂工作。另外，由for和since引导的时间状语不能及终止性动词的肯定式连用，但可和其否定式连用。又如HehasntcometoBeijingsince1992.从1992年以来，他就没来过北京。4.ourteacher_Lindacancometojoinus.A.wishesB.asksc.tellsD.hopes解析：答案为D本题主要考查学生对wish和hope的用法的掌握。hop

19、e后面接从句，其引导的宾语从句的连词that可以省去；而wish后面也可以跟宾语从句，但从句中的谓语动词一般用虚拟语气，也就是couldcome本句中，“老师希望琳达来”这种愿望是发自内心的，而不是说不可能实现。例如：IwishImaylivetoseeit.我希望还能活着看见这件事。wewishIwereyoungagain.要是我能返老还童该多好呀！（以上两句均为虚拟的语气）wehopeyouwillstartoffearly.我们希望你早点动身。Hehopestheycanmeetinchangsha.他希望他们能在长沙见面。5.She_gohomenow.A.hadbetternott

20、oB.hadbetternotc.hadnotbetterD.hadnotbetterto解析：答案为B这里的hadbetter相当于一个情态动词，表示一种语气，意愿，汉语的意思是“最好”，“还是为好”。构成这种句子的否定形式只需在后面直接加not就可以了。例如：youdbetternotgonow你现在还是不走为好。wehadbetternotmakefunofhim我们最好不要跟他开玩笑。注意：not后面不能用to，更不能在had和better中间加not。6.下列各勾划线部分均有一处错误，找出并将序号填入题前括号内（）1）Hehascomebackforamonth.ABcD（）2）Ih

21、aventheardfrommywifesincealongtime.ABcD（）3）janehadonherhatandcoatandwentout.ABcD（）4）Hepaid50yuanonthedictionary.ABcD（）5）Areyousureyouvelookedforthedog?ABcD解析1）A，come是终止性动词，不能和表示一段的时间状语连用，应改为been。2）c，since后须跟时间的（起）点，表示一段时间，alongtime是一段时间，应该将since改为for。3）A，haveon表示状态，此句的意思是“戴上帽子、穿上大衣走了出去”，所以动词需要表示动态的词

22、，应改为puton。4）c，用pay来表示付钱时，它的搭配介词应是for。5）D，lookfor是寻找，而此句问的是找到，所以应使用found。四、习题精选初三英语总复习单元自查练习（UNIT2）疑难解答。（本习题课前发给学生）I用所给词的适当形式填空.Theriverhasbecome_and_sincetwoyearsago.2.we'dbetterkeepthefire_.3._areafraidofnewspapersandTVstations.4.what_weatheritistoday!5.wefindEnglishvery_inourdailylife.答案：1.dir
