D.otherwise,点拨,考查短语辨析。,as a result,结果；,after all,毕竟；,any way,不管怎样；,otherwise,否则。由句意可知要选,as a result,。,6.totally,adv.,整个地,;,完全地,totally blind,全盲,total,adj.,完全的,;,整个的,total silence,寂静无声,in total,总共,7.Over time my memory has developed,so,much,that,.I never forget anything I have been told.,考点,so.that.,引导结果状语从句。,考例,1,The weather was _ cold that I didnt like to leave my

goes home.,9.But I was always so lonely standing there by myself,until,in early 1960s they gave me a family connected by a network.,点拨,until,表示“直到,时”，在肯定句中，指从开始到结束的整段时间，谓语动词一般是延续性的。在否定句中构成,not.until,，意为“直到,才”，指到某一点动作才开始，谓语动词一般是非延续性的。其强调句是,it is(was)not until.that.,。当,not until,位于句首时，句子要进行倒装。,如：,The experts explored the island,until,the end of last year.,直到去年年底，专家们一直都在勘查这个小岛。,We,didnt,solve the problem,until,Mr.Smith helped us.,直到史密斯先生帮助我们，我们才解决了那个问题。,It was,not until,last year,that,my hope became a reality.,Not

police with their enquiries.,有一男子在协助警方进行调查。,2)as well as,也，还，而且,e.gHe grows flowers as well as vegetables.,She is a talented musician as well as being a photographer.,3),这个句子是现在完成时被动语态，其机,构是,(have/has+been+,过去分词）,e.g.The radio has been repaired when,we phoned the shop.,考例,1 Professor James will give us a lecture on the Western culture,but when and where _ yet.(,浙江2007),A.hasnt been decided,B.havent decided,C.isnt being decided,D.arent decided,点拨,本题考查动词的时态、语态及主谓一致。由,yet,可知要用完成时态，又因时间与地点是被决定的，故应用被动语态。此外，“在什么时候和什么地点（做报告）”是指同一件事，故用单数形式。,考例,2 When you get the paper back,pay special attention to what _.(,四川,2007),A.have marked,B.have been marked,C.had marked,D.had been marked,点拨,因,mark,这一动作发生在,get,之前，且试卷是被批注，因此应用现在完成时的被动语态。,考例,3 I got caught in the rain and,my suit _.(,北京,2007),has ruined,had ruined,C.has been ruined,D.had been ruined,点拨,句意为：我遭遇大雨，我的衣服,被淋坏了。,ruin,表示的动作发生在,got,caught,之后，故排除,B,、,D,两项。此处,表示被动，所以,C,项正确。,11.anyhow,无论如何,Anyhow,you can try.,无论如何你可以试试。,I dont care what you say;Im going to do it,anyhow,.,比较,:,somehow,意为“以某种方式,;,不知怎么地”,12.I am now truly filled with happiness,that,I am a devoted friend and helper of the human race!,点拨,that,引导同位语从句，具体说明,happiness,的内容。,that,是连词，在从句中不充当任何成分。英语中用,that,引导同位语从句的情况比较常见，但有时也可以用连接副,(,代,),词,how,when,wherewhether,等来引导同位语从句。注意：,if,which,不能引导同位语从句。,如：,I had the impression,that,she chose her words with care.,在我的印象中，她选词很小心。,I heard the news,that,our team had won.,我听到了我们队获胜的消息。,l have no idea,when,he will be back.,我不知道他什么时候回来。,He must answer the question,whether,he agrees to it or
