4、set up in “在某地建起”， what 引导的从句作介词 in 的宾语从句， what 在从句中作主语。 此题考生易错选 C项，因为前面没有先行词，故不是定语从句。1答案： A5 You cant finish typing it in less than an hour? _.A Yes，I m sure I canB No，hardlyC Sorry ，I can tDI don t think I can6The girl shouted“Go out _ I call the police！”A orB andC untilD before解析：考查连词。 句意：那个女孩大声喊

5、道：“在我还没有叫警察之前请你出去。”即：“再不快滚我叫警察了。”考查before引导的时间状语从句，call用了一般现在时态表示将来。选项A 是陷阱， call改为 will call才选 A 项。答案：D7 There was a financial crisis case last year where the stock price reducedto 45% ， causing people to be _.A in vainB in sympathyC at riskD at a loss解析： 考查介词短语辨析。根据语境“股票价格下降到了45%，致使很多人都蒙受了损失”可知at

6、a loss“亏损”符合语境。答案： D8 Do you know Mr.Johnson has been ill for days? Yes， I wonder if he is _ better now.A someB muchC anyD no解析：考查形容词比较级的修饰语。答语句意： 他是病了， 我不知道他好点了没有。anybetter意为“好了一点”，符合语境。much better， no better虽符合语法，但都不符合该题语境。答案： C9 Excuse me.Is Johnson living here?I m sorry ， but he _ lives here.2A

9、，_.A much sport is neededB one needs to do much sportC much sport is needed by oneD one is needed much sport解析： in order to keep healthy 表示目的，必须用人作主语，并且one 和 need 之间是主动关系，因此B 项正确。答案： B13 Youd better give up smoking.Smoking is the biggest preventable _of lung cancer.I just cant give it up，however har
