3、ke to have done 表示本来希望做而却未做的事。 may (might) + have done表示对过去的推测，多用于陈述句，意思是可能，。might 比may 语气更加委婉。 例如： 例1. (2007福建) -Where is my dictionary?

12、开，但人们都成功地逃出去了，表示过去成功地做了某事只能使用was / were able to do，故本题选D。 二.词语辨析： 1. worth, worthy, worthwhile (1)worth: 只作表语，有某种价值 The picture is worth $ 500. 这幅画值500 美元。 be worth doing 值得做某事 (其后接动名词时，总是用主动形式表示被动意义。) The clock is hardly worth repairing. 这台钟简直不值得修理。 What is worth doing is worth doing well. 值得干的事就得干

20、性定语从句和非限制性定语从句 一.限制性定语从句和非限制性定语从句的概念 1.限制性定语从句： 限制性定语从句对先行词起限制、修饰的作用，关系代词有that, which, whom, who, whose以及关系副词when, where, why等，没有逗号把从句与先行词分开。限制性定语从句是先行词不可缺少的部分，去掉它主句意思往往不明确。例如： Do you know the professor who is speaking at the meeting? Where is the book which I bought this morning? 2.非限制性定语从句： 非限制性定语

21、从句是先行词的附加说明，去掉了也不会影响主句的意思，它与主句之间通常用逗号分开。用法其实与限制性定语从句极为相似，只是不能用that引导。例如： This letter is from his parents, who are working in Tibet. English is an important subject, which every student should study well. 二. 限制性定语从句和非限制性定语从句的区别 1. 从形式上看，限制性定语从句与其先行词紧紧相连，两者没有停顿;非限制性定语从句与先行词之间有逗号隔开。 2. 从意义上讲，限制性定语从句用来修

22、饰先行词，两者密不可分;而非限制性定语从句仅仅对先行词作补充性叙述或说明，两者关系不那么紧密。 3. 从翻译方法来看，一般来说，限制性定语从句多半译成汉语的前置定语，修饰其后的先行词，非限制性定语从句则往往译成后置的并列从句。例如： This is the house which we bought last year. 这是我们去年买的那幢房子。(限制性) This letter is from his parents, who are working in Tibet. 这封信是他父母写来的，他们在西藏工作。(非限制性) 4. 从关系词的使用来看: (1) that不能用来引导非限制性定语

23、从句。 (2) 在非限制性定语从句中的关系词不能省略。 (3) 非限制性定语从句的关系代词which既可以指代前面的先行词，也可以指代前面整句的含义。指代前面整句的含义时，定语从句谓语动词要用第三人称单数，例如： She heard the terrible noise, which brought her heart into her mouth. (which指代noise) He seems not to have grasped what I meant, which greatly upsets me. 他似乎没领会我的意思，这使我心烦。 (Which指代他似乎没领会我的意思这个句子

24、。) (4) as在引导非限制性定语从句时，指代整个主句，有正如，就像之意。as引导的定语从句可放在主句之前，之中或之后，位置灵活。例如：我们都知道，吸烟有害健康这句话可译成： As we know, smoking is harmful to our health. Smoking, as we know, is harmful to our health. Smoking is harmful to our health, as is known to us all. 典题赏析 考例一：He made another wonderful discovery, _ of great impo

25、rtance to science. A. which I think is B. which I think it is C. which I think it D. I think which is 解析答案A。先行词是discovery，定语从句意为这个发现对科学很重要，所以引导定语从句的关系词在从句中做主语，由which引导。I think是插入语，考虑句子结构时可忽略，定语从句就简化成了which is of great importance to science。 考例二：There was _ time _ I hated to go to school. A. a; that

26、B. a; whenC. the; that D. the; when 解析答案B。全句意为曾经有一段时间我痛恨上学。 第一空a time表示一段时间，第二空引起定语从句，且在从句中作时间状语，所以用when。 考例三：Carol said the work would be done by October, _ personally I doubt very much. A. it B. that C. when D. which 解析答案D。从句意为我对Carol说的在十月前能做好这项工作表示怀疑， which代表十月前能做好这项工作这部分内容，并在从句中做宾语。 考例四：(2009重庆)

27、 Professor William keeps telling his students that the future _ to the well-educated. A. belongsB. is belongedC. is belongingD. will be belonged 解析答案A。belong to 不能用被动，也不能用于进行时。 考例五：(2009浙江)I have reached a point in my life _ I am supposed to make decisions of my own. A. which B. whereC. howD. why 解析

28、答案B。a point是先行词，定语从句空白处意为在这一点上，所以用表地点的where。这里表示一个抽象的地点。 考例六：Its none of your business _ other people think about you. Believe yourself. A. howB. whatC. whichD. when 解析答案B。此题意为别人怎么看你跟你无关。相信自己。表示对某人或某物的看法，常用句型有：What do you think? What would you say? What do you think of/about ? How do you feel about ? How do you like sth? Whats your idea/opinion of?等。 精品小编为大家提供的高一必修2英语单元重难点解析，大家仔细阅读了吗?最后祝同学们学习进步。 高一英语必修2第三单元知识点：computers 高一英语下册第一单元知识点：Cultural relics
