Step 1 Presentation
（1）Teacher ask students to read the following sentences and answer the question:
In those days,there were two contradictory theories to explain how cholera spread.One theory was that bad air caused the disease.Another was that cholera was caused by an infection from germs in food or water.Snow subscribed to the second theory.One evidence is that a woman and her daughter had died of cholera after moving away from Broad Street.It seemed that she liked the water from the pump so much that she had it delivered to her house every day.The truth was that the water from the Broad Street pump had been infected by waste.
1.Can you find any predicative clauses
2.Why do you think they are predicative clauses
3.What are the main linking verbs
（2）Teacher help to conclude the grammar- predicative clauses and introduce the usage of the grammar
名词性从句——表语从句
表语从句是在复合句中作表语的名词性从句，放在连系动词之后，一般结构是“主语＋连系动词＋表语从句”。可以接表语从句的连系动词有 be, look, remain, seem等。
1.连接词
类别 连接词 例句
从属连词 that不作句子成分，也没有意义，通常不可省略 My suggestion is that you should have patience. 我的建 议是你应该有耐心。
whether 不作句子成分，但有“是否”的意义，一般不用if代替 The question is whether we can cut down the costs of the product. 问题是我们能否降低产品成本。
because, as if/through等 He has to watch his weight. That is because he has heart disease.他不得不注意自己的体重，那是因为他有心脏病。 It sounds as if someone is knocking at the door. 听起来 好像有人在敲门。
连接代词 who, whom, whose, what, which, whoever, whatever, whichever等。在从句中作主语、宾语、表语或定语 The problem is who can complete the difficult task. 问题是谁能完成这项困难的任务。 This is just what we are always looking forward to. 这正是我们一直盼望着的。
连接副词 when, where, why, how等。在从句中作状语 That is where he was born and brought up. 那就是他出生和被养大的地方。 Their difficulty is how they can clear their debts. 他们的困难是怎样才能还清债务。
2. 需要注意的问题
①as if/though 引导的表语从句的语气
as if/though 引导的表语从句常置于连系动词look, seem, appear, sound, feel 等后。
若表述真实的情况，就用陈述语气；若表述与客观事实相反的假设，则用虚拟语气。
It seems as if he benefits a lot from the project.
看起来好像他从这个项目中获益不少。 (陈述语气）
It looks as if/though he were drunk.
他看上去好像喝醉了。 (虚拟语气）
②表语从句的特殊句式
（The reason why. . .is that. . . ……的原因是····· (why引导定语从句，修饰 the reason, that引导表语从句）
This/That/It is because . . . 这／那是因为······ (because引导表语从句，从句表原因）
This/That/It is why . . . 这／那就是······的原因。 (why引导表语从句，从句表结果）
The reason why he didn't come is that he didn't receive the invitation.
他没来的原因是他没有收到请柬。
The woman was weeping bitterly. That's because her son was drowned in a river.
那位女士痛哭流涕，那是因为她的儿子在河中溺亡了。 (先果后因）
The woman's son was drowned in a river. That's why she was weeping bitterly.
那位女士的儿子在河中溺亡了，那是她痛哭流涕的原因。 (先因后果）
③ 表语从句中的虚拟语气
主语是表示“建议、命令、要求”的名词，如 suggestion, advice, proposal, order, command, request, requirement, demand 等时，表语从句应使用虚拟语气，即从句谓语用“should+动词原形”，should可以省略。
My suggestion is that we (should) set off early tomorrow.
我的建议是我们明天早点儿动身。
His order was that all boys gather quickly around the car.
他的命令是所有男孩子要速在汽车周围集合。
（Justification: Through this part, students can practice the dialogue in pairs and consolidate the grammar.）
Step 3 Production
Work in plete the conversations using the predicative clauses.Every group can choose one or two dialogues,and each member must complete at least two predicative clauses.
1.A:Papermaking,printing,gunpowder,and the compass are the four great inventions of ancient China.They are significant contributions of the Chinese nation to the world.
B:Sure,they are.What I want to know though is .
2.A:The ancient Chinese were the first to invent paper and printing.Then they went on to invent books and had opened bookshops in many cities.

3.A:The compass is a special invention of ancient China,dating back to as early as the Warring States Period.

4.A:Gunpowder was originally used for making fireworks.
B:But what surprises me is .
5.A:High-speed trains,mobile payments,the bike-sharing system,and online shopping are considered by some as the new “four inventions” of China.
B:Is that so I feel/It seems .
（Justification: Students will learn to use the grammar in a proper way through those activities.）
