(人教版)高中英语选修八(教学资料,补习资料)：Unit 2 Cloning复习同位语及语法讲解
复习同位语概念引入同位语，也许这个名词不像定语、状语、主语等那么眼熟，但是在英语语法中也是不可缺少的内容，尤其是同位语从句，更是名词性从句的重点和难点。
在这个单元里，我们就来小结一下同位语，尤其是同位语从句的一些重要的用法。
先看下面句子：1. The whole scientific world followed the progress of the first successful clone, Dolly thesheep.2. Then came the disturbing news that Dolly had become seriously ill.3. Altogether Dolly lived six and a half years, half the length of the life of the originalsheep.4. The fact that she seemed to develop normally was very encouraging.这些句子中斜体词部分都是同位语，其中句2和句4是同位语从句。
那么同位语到底是什么样的句子成分？什么样的词语或从句能作同位语？应该注意什么呢？下面我们将就这些问题进行讨论。
用法讲解同位语的定义与构成同位语（Appositive）定义对句子中某一成分作进一步解释、说明，与前面名词在语法上处于同等地位的句子成分叫同位语。
同位语常放在被说明的词之后, 说明它们的内容、性质和情况等，有时有逗号隔开。
例如：Mr. Wang, my chi ld’s t eacher, will be visiting us on Tuesday.王先生，我孩子的老师，星期二要来看我们。
（Mr. Wang是句子的主语，而my child’s teacher说明主语的身份，是同位语。
）But now the question comes to their minds, “Did she die young because she was a clone?”但是现在他们不得不思考这样的问题：“多莉早死是因为它是一只克隆羊吗？”（句尾的直接引语说明the question的内容，是同位语）同位语的构成1. 名词(短语)或all, each, both等代词及短语(有时有逗号隔开)We students all respect Mr. Johnson, our English teacher.我们学生都很尊敬我们的英语老师，约翰逊先生。

三要素-引导词
（一）名词性从句的一般引导词： 3. 连接代词 who(m), whose, which, what 等引导名词性从 句时，均有各自的意义，在从句中作主语、宾语、定语等。 如：
I don’t know when he XXX come, but when he comes, I’ll call you. 我不知道他什么时候，但当他来的时候，我会打电话给你。
句中第一个when 引导的是宾语从句，故用将来时态表示 将来意义；第二个when 引导的是时间状语从句，故用一般 现在时表示将来意义。
同位语从句-引导词
同位语从句：就是在句中作同位语的从句。它通常放 在thought, idea, news, word(=news), plan, doubt, question, fact, suggestion, belief等抽象名词的后面，说明这些词的具体内容 或含义。同位语从句大多由that引导，也可由whether, how, when, where, why等引导，但不能由if,which引导。
三要素-引导词
（一）名词性从句的一般引导词： 2. 连接词 whether 引导名词性从句也不充当句子成分， 但有自己的意思，表示“是否”；引导宾语从句时，可换 成 if，但引导其他名词性从句时不能换成 if。如：
He asked whether [if] I would show him the way. 他问我是否可 以给他带路。
同位语从句与定语从句的区分
1．意义的不同 同位语从句是用于说明所修饰名词的具体内容的，它与被

2. 当宾语从句是特殊疑问句时, 由特殊 疑问词充当连接词, 因为该特殊疑问 词(即连接词)在从句中担负一定的句 子成分, 具有一定的意义, 所以不可 以省略。
Do you know what he said just now? I don’t remember when we arrived. I asked him where I could get so much money. Please tell me who we have to see. Do you know what time the plane leaves?

Now, who can show your opinion?S: Let me have a try. In my opinion it is wrong to clone human beings. If my parents decided to have a clone made of me, I would feel very sad and I would never accept the clone as a member of the family or as my friend.T: Good job!Step ⅡGrammarT: Do you know the appositive clauses? Please pick out three more examples from the reading passage.Sample answers:The fact is that they are natural clones of each other.The whole scientific would follow the progress of the first successful clone, Dolly the sheep.Altogether Dolly lived for six years, half the length of the life of the original sheep.T: Now let me explain something about the appositive clauses. The appositive clause is a clause used as an appositive. The clause is an explanation to the noun before. The appositive clause belongs to noun clauses. Most of the appositive clauses may be introduced by the conjunction that. A content clause is frequently in apposition with such nouns as fact, news, idea, thought, question, reply, report, remark, hope, belief, suggestion etc.Some examples:Nobody shares my belief that he was mad.My suggestion that he was mad was not accepted.They are familiar with the opinion that all matter consists of atoms.Where did you get the idea that I could not come?We haven’t yet settled the question where we are going to spend our summer vacation.The suggestion came from the chairman that the new rule should be adopted.T: The words the fact are often inserted in front of an object clause when the clause cannot be conveniently connected with the verb either directly or by means of the representative it.This cannot hide the fact that he is growing old.We must face the fact that we are living in a revolutionary world.Some supplements:同位语从句与that引导的定语从句1) 从先行词看同位语从句与名次之间在逻辑上是“主语+be+表语”的关系。

Some scientists take a different view.“While I agree that research on cloning is meaningful，it is inappropriate to use giant pandas in this type of experiment.The number of pandas is limited and human beings have yet to master knowledge about pandas' pregnancy.Cloning would do little to save the species，”said Wang Dajun，a researcher at the School of Life Sciences，Peking University.

第4讲Cloning 语法篇____________________________________________________________________________________________________________________________________________________________________1.掌握同位语从句的结构与功能；2.能够熟练选用合适的引导词。
一. 概述：同位语从句就是在复合句中作名词的同位语的名词性从句。
同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、suggestion、truth、wish、word等。
例如：The news that we won the game is exciting. 我们赢得这场比赛的消息令人激动。
I have no idea when he will come back home. 我不知道他什么时候回来。
The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。
二.同位语从句的功能1.同位语从句对于名词进一步解释，说明名词的具体内容，一般由that引导，例如：1) The king’s decision that the prisoner would be set free surprised all the people.2) The order that all the soldiers should stay still is given by the general.2.whethereg: The question whether we should call in a specialist was answered by the family doctor3.连接代词what，who，whom，whose，which1)I have no idea what size shoes she wears.2)I have no idea which wine is best—it’s a matter of personal taste.3)The question who will take his place is still not clear.三. 同位语在句子中的位置同位语从句有时可以不紧跟在它所说明的名词后面，而是被别的词隔开。
例如：He got the news from Mary that the sports meeting were put off.四. 同位语从句与定语从句的区别(1) 定语从句中的that既代替先行词，同时以在从句中作某个成分（主语或宾语），而同位语从句中的that是连词，只起连接主句与从句的作用，不充当句中任何成分。
(2) 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描述定的性质或特征；同位语从句是名词性的，其功能是对名词进行补充说明。
例如：1) The news that he told me is that Tom would go abroad next year.（他告诉我的消息是汤姆明年将出国。
）（第一个that引导的从句是定语从句，that在从句中作宾语）2)The news that Tom would go abroad is told by him.（汤姆将出国的消息是他讲的。
）（同位语从句，that 在句中不作任何成分）五. 如何判断从句类型：1. 放句首没有用逗号分开的，一般是主语从句，也有可能是状语从句，但从句结束后若有体现时态变化的动词，则一定是主语从句。
2. 放及物动词后，若及物动词不是被动语态，后面一定是宾语从句；若句首为It，该及物动词是被动语态，后面一般是主语从句（It+ is + adj/n./done+ that/whether/when…）或状语从句。
3. 放be动词后，后面就是表语从句，但“It is/was + 从句(被强调成分) + that”是强调句（强调句中“非谓语”）。
4. 放名词后，一般是定语从句，但若该名词有“内涵/内容”( fact/truth/news/ information /problem/suggestion /idea / doubt )，则很可能是同位语从句。
1. (2019重庆卷)—Is it true that Mike refused an offer from Yale University yesterday?—Yeah，but I have no idea ____he did it；that’s one of his favorite universities.A. whenB. whyC. thatD. how答案: B解析: 本题实际上是一个同位语从句，是对名词idea的内容进行的说明。
短语have no idea后面可以使用多种形式的同位语结构，如have no idea where to go等。
根据句意可知使用why表示原因。
故B 正确。

4.(2019浙江温州高二下) Word comes _____ free souvenirs will be given to whoever comes first.A. whatB. thatC. whyD. which答案: B解析: 此题考查同位语从句，从句是对word进行解释，由于从句中不缺少成分，用that引导，所以选B。
5. (2019江苏南昌高二下)---Dad，can you meet my demand I be given a chance to travel to Beijing?A. whichB. thatC. whereD. when答案: B解析: 此句考查同位语从句的引导词，从句是对demand进行解释，从句部分不缺少成分，根据句意应该填that，所以选择B。
