用来列举全部事物，故在被列举事例前面，并用逗号隔开区别上述三个短语的关键是：1）判断是列举部分举例还是列举全部事例，2）在句中的位置。3)举例说明还是列举This machine is very useful in daily life,such as in making bread.这台机器在日常生活中是很有用的，比如做面包。suchas 意思是“像那样的”，其中as为介词，不能同etc.和and so on连用。例如：Such men as Edison,Einstein and Lincoln are great men.像爱迪生、爱因斯坦和林肯这样的人都是伟人。【即境活用】The teacher praised him very often,_he is a good student in our class.A.such

考查短语意思辨析祈使句直接引语变间接引语当我们转述祈使句时，通常将原句中的动词变为动词不定式，并在不定式的前面加上ask,order,tell等转述动词，如果祈使句为否定式，在不定式的前面加上not1.一般变化(1)如果直接引语是表示命令、请求的祈使句，通常将祈使句的动词原形变成动词不定式，并在动词不定式前加上动词ask,tell,order,advise,invite,request,warm,beg,command,encourage等，其中动词的使用须视句义与说话者当时的语气或态度而定注意：a.间接引语中引述动词不能用say。b.如果祈使句是否定形式，则不定式前加上否定词never或not。c.祈使句中的please在间接引语中必须省去。(2)非祈使句形式的请求、命令等的直接引语变为间接引语，变法同上。“Please sit down and have a rest.”she said to us.=She asked us to sit down and have a rest.【点拨】依据说话者的语气，注意转述动词的选择。2.特殊变化（1）若直接引语是表示“建议”的祈使句或疑问句，通常变为“suggested+宾语从句(或动名词)”结构He said,”Lets go to the park.”=He suggested(our)going to the park.【点拨】表示建议、要求、劝告的祈使句都可以用此句型（2）直接引语是感叹句时，间接引语可以用what或how引导，也可以用that引导She said,”What a lovely day it is!”=She said what a lovely day it was.=She said that it was a lovely day.【典型例题】1.The teacher asked us _ so much noise.A.dont make B.not make C.not making D.not to make【解析】选D。考查ask后面复合宾语的用法，即ask somebody to do以及不定式的否定形式，即not to do。2.Please dont stamp the grass.Pardon?I _ stamp the grass.A.tell you dont B.tell you not to C.told you didnt D.told you not to【解析】选D。考查时态。根据情景，应意为“我刚才告诉你”，故主体时态应是I told you；另外应注意的一点和上题一样，即不定式的否定式是not to do。【点拨】掌握祈使句的否定句转换规律【语法专练】将下列句子变为间接引语：1.Mother said to her.daughter,“Hurry up!”_2.“Come at five oclock,”she said to him._3.“Dont swim too far,”I said._4.He said,“Lets leave the luggage at the

phone number?Sorry,_.A.I dont know B.forget itC.here you are D.I cant remember it【答案】选D。【解析】考查情景交际。句意为：你有玛丽的电话号码吗？抱歉，我不记得的了。A相为汉式英语；B项用于回答别人的道歉；C项意为“给你”；D项意为“我不记得的了”，故选D。5.（2010湖北卷T29）Had he her promise,she would have made it to Yale University.A.looked up to B.lived up to C.kept up with D.come up with【答案】选B【解析】该句是典型的虚拟语气，“if”引导的非真实条件句的倒装句，描述的事于过去事实是相反的。“如果她当年履行了自己的诺言，她就会进入耶鲁大学了。”look up to（抬头看，尊重）keep up with（跟上，追上）come up with（追赶上；想出；提出），只有live up to（履行，实行）符合题意。6.（2010陕西卷T24）It is reported that many a new house at present in the disaster area.A.are being built B.were being built C.was being built D.is being built【答案】选D。【解析】考查动词时态，语态及主谓一致。由时间状语at present可知此处动词表示的动作正在进行，主语与所填词是被动关系；many a+名词单数做主语时，谓语动词用单数形式，由此可知本题选D。7.（2009浙江卷T10）It took building supplies to construct these
