23、ot until放在一起加以强调，构成“It is/was not until.that.”句式。(3)在句型“主句until/till时间状语从句或状语”中，尤其应注意以下几点：主句中动词是非延续性动词，如leave，graduate，break等时，必须用否定形式。主句中动词是延续性动词，肯定、否定形式都可以，但意义完全不同。例句：Not until 8：00 did he get down to doing his homework.He didnt get down to doing his homework until 8：00.It was not until 8：00 that

25、ore和never until能用倒装句，而only before和句子意思不相符。句意为：直到她遭遇了困难，才意识到我们的帮助的重要性。故答案为C。语法1复习主语主语是一个句子所叙述的主体，是句子所要说明的人或事物，表示句子描述的是“谁”或“什么”。其位置在陈述句基本结构的前部。可以作主语的有：名词，代词，数词，动词不定式，动名词，名词化的形容词，从句，it(作形式主语)。例句：This means of transport has been tried.这种运输方式已经试过了。(名词)None of us believed her story.我们都不相信她的故事。(代词)Onethird

26、 of the students have finished their homework while others havent.(数词)三分之一的学生完成了作业而其他的人还没有完成。In new China，the old are leading a happy life.在新中国，老年人过着幸福的生活。(名词化的形容词)It is a pity that he cant swim.他不会游泳真遗憾。(it作形式主语)Whether he will come is doubtful.他是否会来还不知道。(从句)注意：(1)动名词作主语时，前面可加代词或名词所有格，表示动名词的逻辑主语。例句

27、：Would you mind my opening the window?我打开窗户你介意吗？(2)动名词作主语，在以下几种情况时，人们习惯用动名词，而不用不定式。主语与表语一致。例句：Seeing is believing.(谚)眼见为实。在“There beno主语”这种结构中，通常用动名词作主语，而不用不定式。例句：There is no getting along with him.(It is impossible to get along with him.)无法和他相处。(3)在以it作主语的句子中，it有以下功能：人称代词例句：Who is the baby in the p

28、icture?照片里的孩子是谁？Its my sister.是我姐姐。非人称代词例句：Its Sunday today.今天是星期天。形式主语，当不定式短语或从句作主语时，常用it作形式主语，位于句首。动名词短语作主语时，有时也可位于某些形容词或名词后面，而用it作形式主语，放在句首。例句：It is important for students to learn English well.对学生来说，学好英语是很重要的。It is so nice talking to you.能跟你交谈真是太好了。用于强调例句：It was in the park that the accident hap

29、pened.就是在公园里才发生那起事故的。【链接训练】Does_matter if he cant finish the job on time?Athis Bthat Che Dit【解析】代词it作形式主语，指后面所说的情况。【答案】D_in an atmosphere of simple living was what her parents wished for.AThe girl to be educated BThe girl educatedCThe girls being educated DThe girl was educated【解析】此题为动名词的复合结构的被动式形式作

30、主语。【答案】C2复习动词(1)谓语动词的分类和知识图解动词实义动词及物动词有些动词只有接宾语，意义才完整，如give，inform，fix等。不及物动词不接宾语，意义也完整，如stand，sleep，cry，explain等。延续性动词能持续一段时间的动词，如learn，live，stay，drive等。瞬间动词不能持续，瞬间发生的动词，如leave，die，marry，hear，see等。静态动词stand，stay，remain，sit，sleep，want，consider，think，wonder等。动态动词fight，work，operate，perform，persuade，pl

31、ant，organize等。动词系动词be(is，am，are，was，were)；become；turn，get，stand，lie，go，feel，sound，look，taste，smell等。助动词将来时will，shall，would一般时be(is，am，are，was，were) do，does，did进行时be(is，am，are，was，were)doing完成时have done，has done，had done被动语态be(is，am，are，was，were)done情态动词can，could，may，might，must，should，ought to等。(2)动词

32、的用法实义动词词义完整，能独立作谓语，可分为及物动词和不及物动词。及物动词后面必须跟宾语，不及物动词后面不跟宾语，但有很多动词既是及物动词又是不及物动词。例句：The post office closes at 9：00 pm.邮局晚上九点关门。Dont move my things.不要动我的东西。The train is moving now.火车开动了。系动词词义不完整，必须和表语一起构成谓语，形成主系表句型。例句：The children went wild with excitement.孩子们兴奋得发狂。助动词没有独立意义，它与其他词一起构成时态、语态、语气、人称、数、否定、疑问等

33、形式。例句：Do you feel like going to the party on Friday night？你在星期五晚上想去参加晚会吗？情态动词用来表达说话人或主语的情感、态度、语气和猜测，它们不能单独作谓语，必须与另一动词原形构成谓语，一般没有人称、数的变化。情态动词包括：can，could，be able to，may，might，must，have to，need，dare，should，ought to，had better，will，shall等。例句：You must get to the airport before nine oclock.你必须在九点以前到达飞机场。

34、延续性动词表示行为或过程能持久地继续下去或能产生持久的影响，非延续性动词表示行为或过程是短暂的或瞬间完成的。例句：This book has been put on the desk for a week.()This book has been lying on the desk for a week.()这本书已经在桌子上放了一个星期了。 (3)动词的时态和语态时态是谓语动词所表示的动作或情况发生时间的各种形式。英语中动词有16种时态，但是常见的只有九种：一般现在时、一般过去时、一般将来时、现在进行时、过去进行时、现在完成时、过去完成时、过去将来时和现在完成进行时。动词的语态主语和谓语是被

35、动关系，即主语是动作的承受者，则谓语为被动语态，被动语态由“be过去分词”构成。【链接训练】Many people expect that credit cards will eventually_paper money for almost every purchase.Atrade BexchangeCreplace Dreduce【解析】考查动词词义辨析。句意为：许多人预计在任何一个购买领域，信用卡都将最终会取代纸币。replace“替代，取代”，符合题意。【答案】CMany of the men have gone off in search of higher pay，_women

36、to carry on with the farm work.Aleft BleavingCto leave Dhaving left【解析】根据句意，此处用现在分词短语作结果状语，D项时态不正确。【答案】BA new cinema_here.They hope to finish it next month.Awill be built Bis builtChas been built Dis being built【解析】They hope to finish it next month.一句已表明“新电影院未完工”，且因cinema与build之间存在被动关系，所以应用被动语态的进行时形式，选D。专心-专注-专业
