Unit 1 Cultural relics教案Grammar(The Restrictive and Non-Restrictive Attributive Clause)Aims:To learn about the restrictive and non-restrictive attributive clauseTo discover some useful words and expressionTo discover some useful structuresProcedures:I. Warming upWarming up by discovering useful words and expressionPlease turn to page 3. Do exercises 1, 2 and 3 first. Please check your answers against your classmates’.Warming up by explainingNow, class, since you’ve read the passage, could you explain to me how to use the phrase “belong to”? The word “to” here is a preposition, indicating the possession, and is always followed by nouns or pronoun. Look at Ex 3.II. Learning about Attributive Clause1. What is an adjective Clause?An adjective clause is a dependent clause which takes the place of an adjective in another clause or phrase. Like an adjective, an adjective clause modifies a noun or pronoun, answering questions like “which?” or “what kind of?” Consider the following examples:Adjectivethe red coatAdjective clausethe coat which I bought yesterdayLike the word “red” in the first example, the dependent clause “which I bought yesterday” in the second example modifies the noun “coat.” Note that an adjective clause usually comes after what it modifies, while an adjective usually comes before.In formal writing, an adjective clause begins with the relative pronouns “who(m),” “that,” or “which.” In informal writing or speech, you may leave out the relative pronoun when it is not the subject of the adjective clause, but you should usually include the relative pronoun in formal, academic writing:informalThe books people read were mainly religious.formalThe books that people read were mainly religious.informalSome firefighters never meet the people they save.formalSome firefighters never meet the people whom they save.Here are some more examples of adjective clauses:the meat which they ate was taintedThis clause modifies the noun “meat” and answers the question “which meat?”.They’re talking about the movie which made him cryThis clause modifies the noun “movie” and answers the question “which movie?”.They are searching for the student who borrowed the bookThe clause modifies the pronoun “student” and answers the question “which student?”.Did I tell you about the author whom I met?The clause modifies the noun “author” and answers the question “which author?”.2. Restrictive & non restrictive clausesDo the following pairs of sentences mean the same thing?1a My uncle, who lives in London, is very rich.2b My uncle who lives in London is very rich.2a The policies, which were unpopular, were rejected by the voters.2b The policies which were unpopular were rejected by the voters.3a My niece, whose husband is out of work, will inherit the house, which I have always treasured. 3b My niece whose husband is out of work will inherit the house which I have always treasured. The first sentence in each pair has a non-restrictive clause within two commas, and the second has a restrictive clause. A non-restrictive clause simply adds more information into the sentence and does not affect the meaning of the main clause: it is therefore bracketed off with commas (1a = an uncle who happens to live in London). Conversely, a restrictive clause defines its referent in the main clause more specifically and contributes significantly to the meaning of the sentence. Thus it is that particular uncle who lives in London who is referred to (1b). In 2a, all policies were unpopular and all were rejected, whereas in 2b only the policies that were unpopular were rejected. Note that in restrictive clauses the non-human relative pronoun is either ‘that’ or ‘which’, whereas for human referents the relative pronoun can be either ‘who/m’ or ‘that’ (the man that/whom I will marry ....).3. A test on FORMAL ADJECTIVE CLAUSESDirections: Combine the sentences. Use formal written English.Use (b) as an adjective clause. Punctuate carefully.1) (a) An antecedent is a word. (b) A pronoun refers to this word.An antecedent ____2) (a) The blue whale is considered the largest animal that has ever lived.(b) It can grow to 100 feet and 150 tons.The blue whale ____3) (a) The plane was met by a crowd of 300.

Unit1 Grammar 教学设计教学设计设计意图This is the last teaching period of this unit, aiming to help students get more about the basic knowledge of the grammar, the attributive clause, in this unit. The attributive clause is a very important grammar item. The emphasis of this period is mainly placed on its classification. Therefore, teachers should create a relatively real context to present enough sentences for students to revise what they have learned about this grammar item. In the meantime, teachers should offer more opportunities for students to practice and make sure students know how to clarify the restrictive and non-restrictive attributive clauses. Exercises designed ought to be simple and easy to operate, which is of great help to students’ understanding.教学重点Enable students to clarify the restrictive and non-restrictive attributive clauses.教学难点Enable students to make sentences containing attributive clauses in a real situation.知识目标Help students to know how to clarify the restrictive and non-restrictive attributive clauses.教学过程Task 1 复习旧知Lead-inT: Hello, everybody! Today we are going to learn more about the attributive clause. First, look at the screen and make the sentences according to the pictures, using attributive clauses.1: It is our classroom which/that is bright.2: This is our English teacher who/that we all love.3: This is our English teacher whose pronunciation is perfect.T: (Write the sentences on the blackboard.) Now look at the blackboard. Let’sanalyze these sentences.1. It is our classroom which/that is bright.↓↓main clause(主句) subordinate clause（从句）It is (our classroom) (which/that) is bright.↓attributive clause（定语从句）↓↓antecedent（先行词）relative pronoun (act as the subject in the attributive clause) （关系代词）2.

More sentences from the textbookGive students several minutes to find out the antecedent and relative pronoun of each sentence,1. This gift was the Amber Room, which was given this name because several tons of amber were used to make it,2. The amber which was selected had a beautiful yellow-brown colour like honey.3. It was also a treasure decorated with gold and jewels, which took the country’s best artists about ten years to make.4. However, the next King of Prussia, Frederick William I, to whom the amber room belonged, decided not to keep it.5. Later, Catherine Ⅱhad the Amber Room moved to a palace outside St Petersburg where she spent her summers.6. This was a time when the two countries were at war.7. There is no doubt that the boxes were then put on a train for Konigsberg, which was at that time a German city on the Baltic Sea.Ⅱ. Conclusion定语从句有两种：(1) 限制性定语从句（先行词与定语从句间无逗号），如句子。

高中英语人教版选择性必修第二册unit 1 Grammar表语从句(ThePredicative Clause)一、表语从句的定义：表语从句就是用一个句子作为表语，放在连系动词之后，充当复合句中的表语，用来说明主语是什么或者怎么样。

The problem is puzzling.主语连系动词形容词作表语The problem is when we can get a pay rise. 主语连系动词一个句子作表语一表语从句二、表语从句的构成：系动词+引导词+简单句What I want to say is that I am tired.三、表语从句的用法.可按表语从句的连系动词有：1).最常用连系动词：be(am; is/was; are/were)o一般在句子中译成：“ 日”7E ...China is no longer what she used to be.2).表变化的系动词：get; turn; go; fall; become; grow; come; run。

用法注意：在英语中，系动词一般只有一般现在时和一般过去时两种时态变化形式，没有其他时态变化形式。

但表变化的这类系动词除外，它们有各种时态变化。

It is becoming colder and colder. The food has gone bad.此处还需注意的是become和turn后接表职业的名词时冠词的有无：Two years later, he became a teacher.但Two years later, he turned teacher.另外，g。

表变化时一般指事情向消极、不好的方面转化。

3).所谓“感官动词”:look; sound; ta ste; smell; fbeL般它们在句子中译成:“・・・起来; ...上去”。

此类系动词为高考高频词。

The food tasted good.食物尝起来很香。
