T:Very good.Now,imagine that you had to describe a computer to someone who lived in the 19th century.How would you explain it?What would you compare it to?You may have a short discussion in groups of three and then write a short description.

(Allow the students a few minutes to discuss and write their compositions.If time limits,allow the students to finish their writing after class.)

Sample description:

Have you seen a computer?Let me tell you something about it.A computer is an electric calculating machine that can store and recall information and make calculations at very high speed.It is a wonderful machine and can do most of the things people can do,but it can work millions of times faster.The first large,modern computer was built in 1946,and people needed a large house to put it in.In the last few years there have been great changes in computers.Today they can be used in many fields.People even use it to pay their bills or order what they want.It is said that in the future computers would arrange everything for people,and do almost all kinds of work.That would be a real computer society!

Step Ⅱ Revision and Lead-in

(Teacher checks the homework exercises first and then shows the following on the screen.)

1.He is a famous scientist.

2.Who’s that girl in red?

3.I’ve read all the books that you lent me.

4.I have lost my pen,which I like very much.

T:That’s all for the homework.Now please look at the sentences on the screen.Pay special attention to the underlined parts.Is there anything in common between them?

Ss:Yes.They all identify the nouns,which are used with them.Each part tells us which thing or person the speaker is talking about.

T:That is to say,the function of each underlined part is the same.Each of them is used as an attribute to describe each noun.Well,are there any differences between them?

S1:Yes.In the first sentence,the attribute is an adjective and put before the noun;the second is a prepositional phrase put after the noun;the third and fourth sentences are full sentences put after the nouns.

T:You are right,what do we call the sentences put after the noun?

Ss:The Attributive Clause.

T:Quite right.In a complex sentence,the clause modifying a noun or a pronoun in the main clause is called an Attributive Clause.The noun or pronoun is called Antecedent.The word that/which introduces the clause(between the noun/pronoun and the clause)is called Relative Pronoun or Relative Adverb.The relative pronouns or adverbs do two jobs at once.They can be used as subjects,objects,attributes or adverbials in the clause;at the same time,they join clauses together.About the use of them,we’ll have particular revision after a while.Now look at the sentences on the screen.

(Teacher shows the following on the screen.)

Complete the sentences with suitable relatives.

1.I know the reason__________he came late.

2.Do you know the woman,__________son went to college last year?

3.The house__________colour is red is John’s.

4.This is the best film__________I’ve ever seen.

5.That is the town__________he worked in 1987.

T:Who’d like to tell me what should be filled in the first sentence?

S2:I think“why”should be filled.Because the antecedent is“the reason”and the relative is used as the adverbial of reason in the Attributive Clause.

T:Yes.How about the second sentence?

(Teacher goes to another student and asks her/him to answer.)

S3:I fill“whose”here.Because the antecedent is “the woman”and the relative is used as the attribute in the Attributive Clause.

T:Right.Sit down,please.Now let’s look at the third sentence.

Suggested answers:

3.whose 4.that 5.where

Step Ⅲ Summarizethe Use of the Non-restrictive Attributive Clause

T:The Non-restrictive Attributive Clause is a clause which gives extra information to the antecedent.So we use a comma to interrupt the sentence.When the Non-restrictive Attributive Clause is cut off,the sentence still ha …… 此处隐藏：7378字，全部文档内容请下载后查看。喜欢就下载吧 ……
