12、unch.答案：set asideset;downset;offset upset about1.Historical research shows that in the 22nd century many people told stories about how,at one time,people could buy robots as house decorators.历史研究表明在22世纪许多人讲到人们曾买机器人作为家庭装修工的情况。句中that引导一个宾语从句；many people told stories about后面有一个how引导的宾语从句。在由that引导的宾语从句中

13、，由于连词that只具有引导作用，并无具体意义，而且不在句中充当成分，因此在口语或非正式文体中常可省略，省略之后对原句并无影响。如：She said(that)she couldnt go with him because she had a lot to do that night.她说因为那天晚上她有很多事情要做，所以不能和他一起去了。提示：在下列情况下，引导宾语从句的that最好不要省略：(1)主从句之间有插入语时。如：It says here,on this card,that it was used in plays.卡片上写着，它过去是演戏用的。(2)若出现两个或两个以上的that

16、ime would be organized into shopping,cooking as well as writing the cards.她计划每天下午都写几张卡片。因为从那时起直到圣诞节，她的时间都安排在了购物、做饭和写卡片上。本句是一个主从复合句，含有because引导的原因状语从句；from then on until Christmas在 从 句 中 充 当 状 语，shopping,cooking,writing the cards为并列宾语。as well as意为“除之外(还)，也，和”。from then on表示“从那以后”“从那时起”；它是一个固定短语，用作时间状

17、语。如：From then on,he never spoke to me.从那时起，他没有同我说过话。From then on,no one killed a seagull.从那以后，没有人捕杀海鸥了。from now on表示“从今以后”，也是一个用作时间状语的固定短语。如：From now on,I will do morning exercises every day.从今以后，我每天都要做早操。活学活用翻译句子从那时开始，他先在一家汽车厂工作，然后在一家钢厂任工程师，当时那是一家最大的钢厂，后来又到了一家生产电脑的公司任总裁。_答案：From then on,he first wo

19、、过去进行时、现在完成时和过去完成时的被动结构是考查重点。被动语态的时态、人称和数的变化主要体现在be的变化上，其变化形式与系动词be的完全一样。以do为例：项目一般时态进行时态完成时态现在am/is/are doneam/is/are being donehas/havebeen done过去was/were donewas/were being donehad been done将来shall/will be done无shall/will havebeen done过去将来should/wouldbe done无should/would have been doneEveryones p

21、k until all the preparations _.Aare being madeBwill be madeChave been madeDhad been made答案：C考查时态和语态。句意：直到一切准备就绪，我们才开始工作。until从句中要么用现在完成时表示动作的完成要么用一般现在时表将来。the preparations 与make之间是逻辑上的动宾关系，故选C项。(2)(2013辽宁30)We are confident that the environment _ by our further efforts to reduce pollution.Ahad been

22、improved Bwill be improvedCis improvedDwas improved答案：B考查时态和语态的用法。句意：我们很自信，通过我们进一步的努力来减少污染环境将会得到改善。由句意可知，应该用一般将来时的被动语态，故B项为正确答案。(3)(2013北 京 23)Shakespeares play Hamlet_ into at least ten different films over the past years.Ahad been madeBwas madeChas been madeDwould be made答案：C本题考查动词时态语态。句意：莎士比亚的戏剧哈

23、姆雷特在近几年来已经被拍成了至少10部不同的电影。由时间状语over the past years可知本句要用现在完成时态，故正确答案为C项。.主动语态表被动意义1有些动词如read,write,clean,wash,iron,burn,draw,cook,keep,cut,open,blow,peel,sell,act等用作不及物动词且表示主语的某种属性时，常和副词well,easily,smoothly等连用，且通常用主动结构表示被动含义。这些动词的主语一般是表物的词，且这些物往往具有某种内在的特点，这些句子的时态多用一般现在时或一般将来时。例如：This pen writes smoot

24、hly.这笔写起来很流畅。The cloth washes well.这种布料耐洗。2动词need,require,want,be worth后加v.ing的主动结构表被动意义。My watch cant work;it needs repairing.我的手表不能用了，需要修了。This film is really worth seeing.这部电影的确值得看。.不用于被动语态的情形1不及物动词(短语)如appear,happen,remain,take place,come about,break out,come true等没有被动语态。A fire broke out during

25、the night.夜间发生了火灾。.动词不定式的被动形式和用法当不定式的逻辑主语是这个不定式所表示的动作的承受者时，不定式一般要用被动形式。不定式的被动式可分为一般时和完成时。一般时：to be done表示动词不定式的动作发生在谓语动词之后或同时发生。完成时：to have been done表示不定式的动作发生在谓语动词之前。He didnt expect the book to be received so well.他没想到这本书会受到如此热烈的欢迎。Im pleased to have been given this opportunity.给了我这次机会我很高兴。典题赏析(4)(

26、2014北 京 28)There are still many problems _ before we are ready for a long stay on the Moon.AsolvingBsolvedCbeing solvedDto be solved答案：D考查非谓语动词的用法。根据主语problems和solve之间的逻辑关系可排除A项；再根据从句的内容可知，这些问题还没有得到解决，故应用不定式表示还未发生的动作。句意为：在准备好长期待在月球上之前我们还有许多问题需要解决。.不定式的主动形式表被动意义1动词不定式放于名词或代词之后作定语，不定式和名词之间构成逻辑上的动宾关系，同

27、时又和句中另一名词或代词构成逻辑上的主谓关系时，不定式的主动形式表示被动含义。Would you bring me a bench to sit on?你给我拿个凳子来坐好吗？典题赏析(5)With the world changing fast,we have something new_with all by ourselves every day.AdealBdealtCto dealDdealing答 案：Cdeal with作 代 词 something的 后 置 定 语 与something构成逻辑上的动宾关系，同时又和句子的主语we构成逻辑上的主谓关系，故使用deal with的

28、主动形式表被动意义。点津如果动词不定式作后置定语，不定式和所修饰的词构成逻辑上的动宾关系，但其逻辑主语不是句子的主语时，则使用动词不定式的被动形式。Ill go to the post office.Do you have a letter to be posted?我要去邮局。你有信要寄吗？(post与主语you之间不存在主动关系，只和前面letter构成逻辑上的动宾关系。)2在“主语be形容词不定式”句型中，形容词后跟不定式作状语，而句子的主语又是动词不定式的逻辑宾语时，常用不定式的主动形式表达被动含义。这样的形容词很多，常用的有：amusing,cheap,comfortable,dan

29、gerous,difficult,easy,fit,hard,important,impossible,interesting,nice,pleasant,funny,heavy,light等。That question is difficult to answer.那个问题不容易回答。典题赏析(6)Tom asked the candy makers if they could make the chocolate easier _ into small pieces.A.break B.breaking C.broken D.to break答案：D考查非谓语动词。句意为：汤姆问糖果制造商

30、他们能否把巧克力制作得更易弄碎。该句中的形容词easier为宾语补足语，相当于表语的作用，其后应该使用不定式结构，类似于It isadj.to do.结构，故选择D项。3在too.to.结构中，不定式前面可加逻辑主语，所以应用主动形式表示被动意义。This book is too expensive(for me)to buy.这本书太贵，我买不起。4在there be.句型中，当动词不定式修饰名词作定语时，不定式用主动形式作定语重点在人，用被动形式作定语重点在物。比较：There is a lot of work to do.(用to do可看成是for us to do)There is

31、a lot of work to be done.(用to be done“谁”做工作不明确)5be to blame常用主动表示被动。Who is to blame for starting the fire?谁应为放火受责备？典题赏析(7)Mr Green stood up in defence of the 16yearold boy,saying that he was not the one _.AblamedBblamingCto blameDto be blamed答案：Cto blame在句中作the one的定语。to blame为固定用法，用主动形式表达被动意义。句意为“格
