2. Master the differences between the appositive clause and the attributive clause
Teaching Difficult Points:
1.master the differences between the appositive clause and the attributive clause
Teaching Methods:
1. Inductive method to introduce the difference between the appositive clause and the attributive clause
2. Practice to help students master the appositive clause
3. Individual or pair work to make every student work in class
Teaching Aids:
1. A projector
Teaching Procedures:
Step 1 Lead in
a. Review the text and present the appositive clause by asking questions:
1.What impresses you most in the passage ?
The fact that … impresses me most.
2.What have you already known before reading the passage ?
I have known the fact that …
3.Did you hear any news about Britain recently ?
I heard the news that …
b. Collect answers as many as possible ,reminding students of sentence structure if find errors.
Step 2 Tell the function of the following sentences.
Now, please open your book, turn to page 37. There are 6 sentences. We have learned these sentences before. You can look at some other sentences on the slide, and then decide which part the clauses act as.
Step3. Practice
Now turn to the exercise3. Join each pair of sentences using a noun clause as appositive. Now you know that the appositive clause is often put behind some nouns, like belief, fact, hope, idea, news, problem, suggestion and so on. Before you do it, go through what is the appositive clause. First look at the example, the noun “ news” is followed by the appositive clause “ that the famous British singer will come to China”. It explains the concrete contents of the noun “news”. Now do you know how to do this exercise?
Step4. Discussions
T: Now look at the picture on page38. Do you know him? He is the famous English film star, named Pierce Brosnan. Please read his profile.
T: Which fact do you think is new to you? Please express your ideas using the noun clauses. Discuss in pairs or in groups.
S1: I thought he is from England. I didn’t know he is from Ireland.
S2: the fact that his first wife died of cancer in 1991 is surprising.
S3: I don’t know that he owns a production company with a ling-time friend.
Step 5 Grammar Explanation
a. Get students to identify the clauses .
c. Try to make students tell the differences between appositive clause and attributive clause by comparing the sentences.
1.The news that the plane would take off on time made everybody happy.
2.The news that is spreading around the airport is that a heavy storm is coming.
3.The suggestion that students should learn something practical is worth considering.
4.The suggestion that they are considering is that students should learn something practical.
c. The teacher offers explanation if necessary.
Step6. Summary
T: In this period, we’ve done some exercises about some important words and the noun clause, especially we practice the appositive clause. Also we ‘ve known the difference between the appositive clause and the attributive clause. After class, you should practice more to master them better. Ok. That’s all for today. See you.
名词性从句介绍
名词性从句包括：主语从句，表语从句，同位语从句，其关联词有连接词that, if, whether; 疑问代词who, what, which和疑问副词when, where, how, why等。
⒈ 主语从句
⑴ 主语从句在句子中充当主语，句子的谓语动词用第三人称单数。
E.g. Why he refused to work with you is still a mystery.
Whatever comes is welcome.
⑵ 主语从句前的that不能省略，仅起连接作用，有时候为保持句子平衡，that从句后置，而由it作形式主语。
E.g. That he became a lawyer may have been due to his mother’s influence.
It is not true that he has moved to New York.
⒉ 宾语从句在句子中充当宾语
E.g. I don’t know where the sound came from.
Don’t be satisfied with what you have achieved.
如果主句的谓语动词是及物动词make, find, see, hear等，则把宾语从句置于宾语补足语之后，用it作为形式宾语。
We find it necessary that we practise spoken English every day. 我们发现每天练习口语英语很有必要。
⒊ 当从句放在系动词be, look, remain, seem等后构成表语从句。
E.g. The trouble is that I have lost his address.
It seemed that the night would never end.
⒋ 同位语从句
同位语从句是对与之同位的名词中心词作进一步解释，能接同位语从句的常见名词有：idea,fact,news,belief,hope,evidence,opinion,problem,truth,proposal,theory,decision.discovery.problem,thought.understandin,promise等。
E.g. The fact that we talked about is very important.(定语从句)
The fact that he succeed in the experiment pleased everybody.(同位语从句)
注意：名词性从句的难点在于其句型结构不同，所使用的连词比较复杂。因此，如何确定正确的连词是突破名词性从句的关键。解决这一问题可以从以下几点入手：
⑴ 依据“缺什么补什么”原则确定正确的连词。所谓“缺什么补什么”是指句型结构与连词之间的关系。如果句子中缺主语，指人用who，指物用what；如缺宾语，指人用whom，指物用what；如缺时间状语用when；地点状语用where；原因状语用why；方式状语用how；定语用what或which；什么都不缺用that。
I know what he is talking about.（缺宾语指物）我知道他正在谈论什么。
I’m sure that he will come tomorrow.（什么都不缺）我确信明天他会来。
Where he will go is unknown.（缺地点状语）他要去哪儿还不知道。
I don’t know which book I should choose.（缺定语）我不知道应该选哪本书。
⑵ 注意几组易混连词whether与if；that与what的使用：
⑴引导主语、表语、同位语从句时关联词只用whether不用if 表“是否”。引导宾语从句时whether, if均可。
Whether he will attend the meeting is uncertain.
The question is whether he will come.
⑵宾语从句中，whether常与or not搭配，也可以说 whether or not, 而不说if or not.
E.g. I don’t care whether or not she will attend the meeting.
⑶whether也可用在介词 后，或带to 不定式前，if or not.
E.g. She doesn’t know whether to get married now or wait.
I haven’t settled the question of whether I’ll go back home.
⑷ 某些动词后面（如discuss）只能用whether, 不用if .
E.g. We discussed whether we should go on climbing.
The question is whether the film is worth seeing. 问题是这部电影是否值得看。
Whether we shall attend the meeting hasn’t been decided yet. 是否我们要参加这次会议仍未被决定。
We don’t know whether/if she is ready. 我们不知道她是否准备好了。
that引导从句时不做成分，无意义；而what在从句中充当成分，有意义。
What he says is important. 他所说的很重要。
That light travels faster than the sound is a fact. 光传播速度比声音快是个事实。
