典型例题

  1.He may have plans, but he hasn’t yet spoken to me about them.
  【考点】may(might)表示推测的用法。
  【考例】一Are you coming to Jeff’s party?
      -I’m not sure.I ________ go to the concert instead.
  A.must  B.would  C.should  D.might
  【简析】may除作“可以”解(表示‘“许可”或“请求允许”)外,还常表示“把握不大的猜测”,意为“也许、或许、有可能”,在口语中,常被might代替,只是可能性比may更小,有时在语气上显得更婉转些。根据答语中的I’m not sure.(我没有把握),可知“我有可能去听音乐会”。故本题选D。
  2.But some people don’t want good farmland to be built on.
  【考点1】动词不定式的被动式(to be built on)作宾语补足语。可以带这种宾语补足语的动词有want,expect,allow,ask,tell,cause,force等。此外,不定式的被动式还可用于be likely,be said,seem,appear,claim,remain等后,表示与其逻辑主语(即句子的主语)存在着动宾关系。如果该动作发生在谓语动作之前,则用不定式的完成被动式“to have been +过去分词”
  【考例】Having a trip abroad is certainly good for the couple, but it remains _______ whether they will enjoy it.
  A.to see  B.to be seen  C.seeing  D.seen
  【简析】whether引导的主语从句用的是将来时,意为“(但)他们是否喜欢(我们将拭目以待)”。故本题选B。
  【考点2】make,have及感官动词see,hear,watch等的宾语补足语,多用过去分词表示这种被动含义,而不用不定式的被动式。
  【考例】The managers discussed the plan that they would like to see ______ the next year.
  A.carry out  B.carrying out
  C.carried out D.to carry out
  【简析】that they would like to see是定语从句,that指the plan,在从句中作see的宾语,与补足语“实施”是动宾关系。故本题选C。
  3.In glasshouses, computers control the watering of the plants as well as the light and the temperature.
  【考点】as well as用作并列连词,相当于not only… but also…,但侧重点在前项,连接并列主语时,谓语动词的数取决于前项。而no only….but also…的侧重点在后项,谓语动词的数按就近原则处理。
  【考例】E-mail,as well as telephones________ an important part in daily communication.
  A.is playing B.have played C.are playing D.play
  【简析】该题主要说明前项E-mail的情况,谓语动词随之为单数。故本题选A。
  5.So people will be advised to keep fit in many ways.
  【考点】keep fit意为“保持健康”,也可以说keep healthy,keep well。其中keep为系动词,意为“保持在某种状态下”。不过keep well还可指“(食物)保持新鲜”。
  【考例】-Mummy,can I put the peaches in the cupboard?
      一No, dear.They don’t________ well.Put them in the fridge instead.
  A.keep  B.fit  C.get  D.last
  【简析】根据句意“桃子放在柜子里不会保鲜,要放到冰箱里”可知,此处应选A项才符合题意。
  例1 The news_______ he would go to Japan on business is not the one _______ he told me.
  A.which; that B.that;which C.which;which D./;that
  此题考查同位语从句与定语从句的区别。同位语从句一般跟在belief,fact,hope,idea,news,problem,possibility等名词后面,用以说明或解释前面的名词,引导同位语从句的词有连词that,whether或连接副词when,how,why等;定语从句与前面的名词有修饰与被修饰、限制与被限制的关系,引导定语从句的有关系代词that,which等或关系副词when,where等。本题前一句是“他将因公到日本去”这个消息,是同位语从句,要用连词that,不能省略,后一句“他告诉我的消息”是定语从句,用关系代词that或which作宾语时,也可省略,故B为正确选项。
  例2 Mother made a promise ________ I passed the exam, she would buy me a computer.
  A.if  B.that  C.that if  D.whether
  这是一个由that引导的同位语从句,说明名词promise的内容。同位语从句中又包括一个条件状语从句if passed the exam。故C为正确选项。
