教学过程

Step 1: Lead in

1.Enjoy a beautiful song”as long as you love me ”,and remind the students to pay attention to the sentences in the red bold,guessing what type of clause they belong to。

（活动意图：由一首后街男孩的英文歌曲，激起了学生的学习兴趣，引出今天学习的主题---名词性从句。）

Step 2: Introduction about types of sentences and definition of Subject Clause

1.Types

句子分为简单句、并列句、复合句；复合句包含主句与从句；从句分为形容词性从句（定语从句）、名词性从句（主语从句、宾语从句、表语从句、同位语从句）、副词性从句(状语从句)。

2.Relation

复合句与简单句：复合句 = 简单句 + 引导词 +简单句

位置作用：谓语或系动词之前，在复合句中充当主语。

That Tom won the tennis game surprised the people.（That Tom won the tennis game为主语）

3.Definition

在主从复合句中，充当主语的从句是主语从句(Subject Clause)。它是名词性从句之一，使用陈述句语序。引导的连接词有从属连词、连接代词和连接副词。

（活动意图：以思维导图形式直观呈现句子分类及对应关系，了解语言学中的句子类型和主语从句等概念及其基本构成和功能作用，可以帮助我们更深入地理解句子的结构和功能，从而更准确地表达我们的想法。）

Step 3 Summary about the Usage of the Conjunctions

介绍主语从句的引导词。

（活动意图：通过介绍主语从句的引导词，我们希望学生能够更加清晰地认识到语法规则在英语学习中的重要性，从而培养他们的语法意识。主语从句的引导词不仅决定了从句的类型，还影响了整个句子的结构和意义。通过学习和练习，学生将能够更准确地分析句子结构，提高阅读和理解能力。）

Step 4 Analysis and Conclusion

从属连词 that，whether, if

1.That the boy didn’t know the answer made the teacher angry.

从属连词：That不做成分，没有意义，不能省略。

2. Whether He can retire to a life of leisure remains to be seen.

从属连词：whether不做成分,但有意义，表“是否”。

Practice

That he will pass the exam is certain.

Whether he will pass the exam is uncertain.

结论：

从属连词 that /whether

that 不做成分，没有意义，不能省略。

whether 不做成分，有意义，译为是否。

【练一练】

1. _________she left him made him heart‑broken.

2. _________ he is still alive is a piece of good news to us.

3. _________ he will come or not is not known yet.

参考答案：That ；Whether ；Whether

Step 5 连接代词（作主、宾、表、定）

what(ever) , who(ever) ,which(ever) ,whom(ever)..

1.What the cat did made the baby cry.

连接代词，做（主语、宾语、表语），译为“东西”，不能省略。

2.Who would convince him to change his mind aroused my curiosity.

连接代词，做（主语、宾语、表语），译为谁，不能省略。

3.Whoever can digest what the teachers teach is likely to get higher scores.

连接代词，做（主语、宾语、表语），译为无论谁，不能省略。

Who will take part in the meeting has not been decided.

What she said is true.

Which book I shall choose hasn’t been decided.

Whoever breaks the law will be punished.

结论：

who在主语从句中充当主语 , 译为谁。

what在主语从句中充当宾语, 译为东西。

which在主语从句中充当定语 , 译为哪一。

whoever在主语从句中充当主语, 译为无论谁。

4.what 与 that在引导主语从句时的区别

what 在从句中充当句子成分，如主语、宾语、表语，而that 则不然。

1. What you said yesterday is right.

2. That she is still alive is exciting.

3. That he lost the bike worried him a lot.

4. What he lost yesterday is his bike.

Step 6连接副词（作状语）when, where, how, why

1.How he attained success is unknown.

连接副词，做（状语），译为怎样，不能省略。

2. When the bomb will explode worries the man.

连接副词，做（状语），译为何时，不能省略。

When the bomb will explode worries the man.

Where she is from is unknown.

Why he was late is not important now.

How he attained success is unknown.

结论：

when在主语从句中充当状语 , 译为何时。

where在主语从句中充当状语 , 译为何地。

why在主语从句中充当状语 , 译为为什么。

how在主语从句中充当状语 , 译为怎样。

Summary‑Usage of the Conjunctions

总结：缺什么补什么

学法指导

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”是指从句与连词之间的关系。

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。

如缺定语用whose或which。

如什么都不缺用that，whether表“是否”。

Step 7 探寻规律

1.主语从句主谓一致问题

1. Whether the patient will be taken is unknown.

主句的谓语动词，大多数使用单数。

2. When and where the patient will be taken is unknown.

由两个连接词引导同一个主从，谓动使用单数。

3. When the task can be finished and whether he can have a rest are unknown.

主语为and连接的两个主从时，谓动使用复数。

4. What he wants most is staying with his family.

What they need are masks(口罩).

what在主从中做宾语时，谓动由表语决定单复数。

2：主语从句的语序

（1） Where we will have a picnic should be discussed. √

Where will we have a picnic should be discussed. ×

（2） How we go for a picnic should be discussed. √

How do we go for a picnic should be discussed. ×

主语从句应使用陈述句语序。

3：主语从句太长怎么办？

That all countries work together is important.

用一个 It 来解决问题！

It is important that all countries work together.

（活动意图：帮助学生深入理解并应用主语从句中的主谓一致原则，同时掌握主语从句的语序，并学会处理主语从句过长时的策略。帮助学生系统地掌握主语从句的相关知识，提高他们在英语语法和写作方面的能力。通过具体的练习和案例分析，学生将能够更好地理解和应用这些知识，从而在英语学习中取得更大的进步。）

Step 8 it作形式主语的用法

1. It is /系动词+ adj. +从句常见的形容词有：

It is possible that... 可能……

It is (un)likely that... （不）可能……

It is obvious that… 很明显…

It is necessary/ essential/... that…

It is possible that(可能)she will come back tomorrow.

It is obvious that(很明显)this measure is effective.

2.It is /系动词+ n. +从句

It is a pity/shame that... 遗憾的是……

It is a surprise that…令人惊奇的是…

It is a pity/shame that(很遗憾) we lost the match.

It is a fact that (这是事实) he cheated in the exam.

3.It + be +过去分词+从句

It is said/told/heard that... 据说……

It is well known to all ... 众所周知……

It is reported/announced ... 据报道……

It is estimated... 据估计……

It is reported/announced(据报道)20 people were killed in the accident.

注：

It is suggested/advised/ordered/requested/insisted/required.. that .. …+(should)do

It is suggested that you (should) spend more time in studying English.

4 It +不及物动词+从句

It happened that... 碰巧……

It occurred to me that…我突然想起…

It seems/ appears that ... 看起来...

It happened that(刚好)I came into the office at that time.

5.练习巩固

1.It is strange that the man should have stuck to his silly ideas.

2.It is a pity that we won't be able to go to the south to spend our summer vacation.

3. What caused the accident is still a mystery.

4. It is said that he has gone to Shanghai.(=He is said to have gone to Shanghai.)

5.It is known to all that gunpowder was first invented by the Chinese.

6.巧记主语从句

整句作主语，其后单谓语

莫忘加连词，that不略但无义

“是否”置前用whether,其他应用靠翻译

主语从句可后置，只需形式主语it把它替
