9、besides+to do(do)，如从句里或介词前有动词do，后面应接不带to的不定式；如无do，则接to不定式，即带do不带to，带to不带do。如：The enemy soldiers had no choice but to surrender. 敌军没有选择只好投降。On Sunday afternoon I had nothing to do but watch TV.

11、is no point ( use, sense, good等名词) + doing sth.Its no use crying over spilt milk. 后悔没有用。It is good playing chess after supper晚饭后弈棋挺好。It is a waste of time trying to explain设法解释是浪费时间。There is no point in my going out to date someone. 现在让我出去和别人拍拖没有用。 There is no use crying over spilt milk牛奶洒了，哭也无用。考点三

12、：在need, require, want, worth (形容词)等词后面接动名词形式表示被动的意思，即用主动形式表示被动意义。如果接不定式，必须用不定式的被动形式。Yourhairwantscutting.你的头发该理了。This problem requires studying with great care这个问题需要仔细研究。Thebookisworthreading.这本书值得一读。考点四：下列短语中to 为介词，后面只能接动名词或名词。（注意：专业四级英语考试对to的考点主要是介词，而非不定式原形） look forward to（渴望），take to（渐渐喜欢）, get

18、h in English. 如果让我教你们，我就用英文授课。 4. 在书面语中, 以上含有were, had, should, could的从句可以把这些词放在主语前面进行倒装，并把if省略。 Had he worked harder, （if he had worked harder,）he would have got through the exam. 他如果工作努力的话，早就应该通过这个考试了。5. 条件句发生的动作和主句发生的动作不一致时，也叫错综时间虚拟条件句。例如：条件句动作发生在过去，主句的动作发生在现在)谓语动词要根据各自表示的时间进行调整。If you had studie

19、d hard last term, you would not be preparing for the make-up exam. 如果上学期你刻苦学习的话，就用不着现在准备补考。 考点二：It is (high /about / good) time that，表示“该是。的时候了”，含有 “为时已晚” 的意思， 表示建议现在应该做什么事，从句一般用一般过去时。It is near midnight.

Id just as soon you had not done it. 我宁愿你没有做此事。（表示事情已经发生。）考点四： wish 句型 表达“但愿，要是多好”的语气wish后宾语从句用虚拟语气，其谓语部分有时态变化：表示对现在情况虚拟时，动词用一般过去时(如did)；对过去的情况进行虚

21、拟时，动词用“过去完成时(如had done)或情态动词的过去时 + 动词的现在完成时(如could have done)”形式；表示将来情况的虚拟时，用“情态动词的过去时形式 + 动词原形(如might do)。”I wish I were a bird.I wish she had not left last night. 要是她昨晚没有离开该多好呀。I wish he would forgive me. 我希望他能原谅我（实际上他不会原谅我）同例： 在as if /as though引导的状语从句中和以 if only引起的感叹句中，谓语动词与wish引导的宾语从句中的虚拟形式相同。例：

22、He talked as if he had known Tom for a long time.He talks as if he were the boss. 他说起话来就像他是老板。If only I were free now！ (注意： if only后面主句被省略，意为：要是那该多好呀！ )If only he had not married! 要是他没有结婚，那就好了！考点五：在强制性语气的宾语从句中， 即表示建议、劝告、命令等主观色彩的动词 + that + (should) + 动词原形， 其中should 经常被省略。这类动词包括：insist, suggest, prop

25、we (should) invite her. 我的建议是我们邀请她。注意二：以上这类动词中有时候有的动词的宾语从句不用虚拟语气，必须根据句子的意思来判断。 What he said suggested (表明) that he did not agree with us.考点六：It is/was + 形容词 + that + (should) + 动词原形，这些形容词主要表示必要性、重要性、强制性、合适性、义务性。如：important, vital, natural, desirable, possible, advisable(明智的), anxious, appropriate, c

28、。.

30、用，分别可以作主语、宾语、表语、同位语等，所以这类从句包括主语从句、宾语从句、表语从句和同位语从句。名词性从句侧重考查考生在一定的语言环境下对英语从句的语序、从句连接词的运用以及主从句时态的呼应等知识点的掌握；考点一：主语从句：主要考查主语从句的引导词；主句的谓语动词，一般用单数。1）It is well-known that the earth moves around the sun. 众所周知，地球围绕太阳转。（说明：由连词that引导的主语从句，在大多数情况下用代词it作形式主语。）2）Whether we will hold a party in the open air tomor

31、row depends on the weather. 我们明天是否在户外开晚会要视天气而定。（此时不能用if引导主语从句，只能用whether。）3）When the sports meet will be held is not decided. 何时举行运动会还没有决定。4）Which car you will choose to buy makes no difference. 你决定买哪一辆车都不会有任何区别。考点二：宾语从句：主要考查宾语从句if与whether的用法区别：1）whether和if常与or not连用，whether和or not 既可合起来使用，也可分开使用；if

32、和or not只能分开使用。如： He asked whether(if)they would come or not.他问他们是否该来。 I dont know whether or not they will come.我不知道他们来不来。2）whether 引导的宾语从句一般是肯定句，if 引导的宾语从句可以是肯定也可以否定的。如: She asked whether/if you had enough money.她问你是否有足够的钱。 I dont care if it doesnt rain.我不在乎是否下雨。（只能用if)考点三：表语从句：be动词或者系动词后面跟主语补足语。1）

33、The question is whether the book is worth reading at all.（问题是这本书是否值得一读。）2）That is why we dont like it.考点四：同位语从句（专业四级英语考查的重点）同位语从句的特点是由一个抽象名词+that从句构成，引导词一般是that, 而且that在从句中不充当任何成分。这些抽象名词有：news, idea, fact, doubt, evidence, promise, rumor, hope, truth, belief, message等，同位语从句是对抽象名词进行说明解释。如：1）We heard

34、the news that he had won the game. 我们听到消息他赢得了比赛。 试比较：2）We heard the news that he had told her. 我们听到他对她说的消息。（宾语从句）例2中的that从句的作用相当于一个形容词，其作用是修饰the news；例1中的that从句的作用相当于一个名词，是对the news的进一步说明。 有时如果主句的谓语动词较短，为保持句子平衡，避免头重脚轻，同位语从句也常与要说明的名词分开。例如：Word came that he died yesterday. 消息传来说他昨天死了。说明：当名词doubt用在否定句中

35、时，其后的同位语从句应用that引导；而用在肯定句或疑问句中时则可以用其他词来引导。例如：I never have the doubt that you can look after yourself. 我从没有怀疑过你可以照看好自己。Some people have the doubt how such a little boy can lift so heavy a box. 这么一个小男孩怎么能举起这么重的盒子，对此人们表示怀疑2形容词性从句（即定语从句）（复合句考查的重点）定语从句主要用来修饰它前面的先行词（名词或代词）的从句，所以又称形容词从句。根据与先行词的关系，定语从句可分为限制

36、性定语从句和非限制性定语从句。定语从句主要考查引导定语从句的关系代词和关系副词；介词引导词以及非限制性定语从句。对于定语从句，在历年专业四级英语试题中，相对集中地考查了非限制性定语从句、关系代词和关系副词的选用、定语从句中的一致关系以及介词+关系代词等知识点。考点一：引导定语从句的引导词有关系代词（who, whom, which, that, whose）和关系副词(as, when, where, why)等。但是当下列情况出现时，对引导词有特殊要求。1） 当先行词是all, everything, nothing, something, little, much时；当先行词被all, n

37、o, some, any, every, a few, a little, much, only, very修饰时；当先行词被序数词或形容词最高级修饰时，或者先行词既有人又有物时，定语从句的引导词用that。例如:Everything (that) he said seemed quite reasonable. 他所说的每件事似乎都很有道理。You can take any toy that you like. 你可以拿走任一件你喜欢的玩具。The first thing (that) I saw will never be forgotten.我永远不会忘记我见到的第一件事情。This i

38、s the last thing (that) I want to do. 这是我最不想做的事情。They are talking about the things and persons (that) they can remember in that country. 他们正在谈论他们所能够记起的那个国家的人和事。 2）why引导表示原因的定语从句，其先行词一般是reason。当主句主语是reason时，作主句表语的成分不能有because和because of 。其结构一般为the reason whyis that，或者 the reason that is that，如：He did

39、 not tell us the reason why he was late again. 他没有告诉我们他为什么又迟到了。The reason why （that）he didnt come is that he was ill.考点二：考查“介词 + 关系代词”引导定语从句的用法。当先行词在定语从句中作介词的宾语时，往往可以把介词放在关系代词之前，构成介词 + 关系代词(whom / which)结构。但一些短语动词(如look after等)中的介词不能与动词分开，故不能放在关系代词之前。 American women usually look upon their best frie

40、nd as someone with whom they can talk frequently. 美国妇女通常把她们最要好的朋友看成是可以经常倾诉的对象。 （关系代词whom在定语从句中作介词with的宾语，talk with sb.意为与某人谈话。）另外，我们还要注意部分 + of 介词+ 关系代词（整体名词）结构，该结构，做关系词也就是 部分名词 + of which/whom的结构，往往可以翻译成“其中”。(学位考查重点) He invited many scientists to his birthday party, two of whom were his old classma

41、tes. 他邀请了许多科学家出席他的生日宴会，其中有两位是他的老同学。考点三：当先行词为表示时间的名词（如：time, day, year, week, month, occasion）或地点的名词（如：place, room, city, country）时，一般用关系副词 when 和 where. 分别相当于in which, at which, on which。但是当这些表示时间或地点的名词作从句的宾语时，则要用关系代词that 或which。I cant forget the days when (in which) I studied with you.Can you tell

42、me the day when （on which） you met her for the first time?China is the only country where (in which) wild pandas（熊猫）can be found.Ill never forget the village where (in which) I spent my childhood（童年）.试比较：I will never forget the days that/which I spent in Beijing University. (本句days 作spend 的宾语，故用关系代词

43、that / which )I have never been to Beijing, but its the place that I most want to visit. (place 作visit 的宾语。)考点四：非限定性定语从句不能用that引导, 一般用引导词which / as或who（指人），非限定性定语从句既可以修饰主句的部分内容，也可修饰主句的全部内容。as引导的非限定性定语从句既可以放在主句之前，也可以放在主句之中或之后，但which或who引导的非限定性定语从句不能放在主句句首。（考查重点）The large area is covered with thick sn

44、ow, which has been reported on TV. 大片区域为积雪所覆盖，这已在电视里报道了。His speech, which was very boring, was over at last. 他的讲演，非常枯燥，终于结束了。Her sister, who lived in another city, was coming to visit her.As we all know, the moon（, as is known to us.）is a satellite of the earth.（as is known to us.）3副词性从句（状语从句）引导状语从句

45、的关联词是一些从属连词。状语从句同状语一样，在句中的位置比较灵活，可置于句首、句末或句中，状语从句位于句首时，常用逗号与主句隔开。若从句较短同时又与主句的关系十分紧密时，也可以不用逗号分开。状语从句根据其用途可以分为时间状语从句、地点状语从句、原因状语从句、结果状语从句、比较状语从句、目的状语从句、条件状语从句、让步状语从句和方式状语从句九种。状语从句的关键是要掌握引导不同状语从句的常用连接词和特殊连接词。现分别列举如下：1）时间状语从句常用引导词：when, as, while, as soon as, before, after, since , till, until 特殊引导词：the

46、 minute, the moment, every time, immediately, no sooner than, hardly/ scarcelywhenA good storyteller must be able to hold his listeners curiosity until her reaches the end of the story 一个善于讲故事的人必须能够自始至终抓住听众的好奇心。He made a mistake，but then he corrected the situation before it got worse他犯了错误，但没等局势恶化，他就

47、扭转了局势。I gave her the money you owed her the moment I saw her我一见到她就把你欠她的钱给她。No sooner had I arrived home than it began to rain. 我一到家就开始下雨了。2）地点状语从句常用来引导地点状语从句的关联词有where，wherever等。The famous scientist grew up where he was born and in 1940 he came to Shanghai 那位著名的科学家在出生地长大，于1940年来到上海。Wherever I am I will be thinking of you. 不管我在哪里我都会想到你。3）原因状语从句常用来引导原因状语从句的关联词有because，as，since等。特殊引导词：seeing
