在具体语境中运用表语从句。
二、教学目标

三、教学步骤
Step I Lead-in
1. Do you know the meaning of the sentences Ask the students to translate the sentences.
1. That’s how most accidents happen.
2. Copies of keys are just what thieves used to break into an apartment.
3. That’s how you quickly get to know the people in your building. Guide the students to find the characteristic of the boldface.
The teacher explains the definition of a predictive clause:
The clause is used as a predicate nominative of a link verb. Predicative clauses begin with that, whether, as if, who, what, which, whose, when, where, how, why.
（设计意图： 补充活动，通过翻译句子和引导学生分析句子，使学生明白表语从句的定
义。）
2. Read and underline (Activity 17)
Ask the students to read the sentences and discuss with their partner to decide which sentences have the same structure with the bold above.
Check the answers and guide the students to find out the location, the guide word, the word order and the structure of predictive clause.
表语从句的定义：充当表语的从句 位置：系动词后
引导词：根据成分和意义确定缺什么，填什么。 语序：陈述句语序
构成：(系动词) + 引导词 + 简单句 Reference answers:
1, 2, 4, 5, 6, 7
Pay attention to Sentence 3 is an object clause, Sentence 8 is an attributive clause. （设计意图：呈现活动，让学生了解表语从句的结构。）
Step II Presentation
1. Read and match (Activity 19)
Give the students 3 minutes to match the sentences independently.
After finishing the exercise, they can work in pairs to check their answers. Encourage some pairs to share their answers and give the feedback.
Reference answer:
(1) b (2) d (3) c (4) a
（设计意图：学生在理解从句的基础上进行匹配，降低了难度。）
2. Explain the grammar to the students.
(1) 表语从句通常跟在以下动词之后
It was because he didn’t pass the exam. It seems (that) he was late for the train. It appears that she was wrong.
It seems to me that we should answer for this.
It appears to her that he wants to teach us all he has.

① The fact is that he left. 事实是他离开了。
② The truth is that I didn’t go there. 事实是我没去那儿。
whether
My question is whether he left (or not).

Step III Practice

2. Role play. Ask the students to read the dialogue in pairs. Encourage some pairs to act out the dialogue.
（设计意图：让学有余力的学生两人一组问答练习，更多地操练表语从句。）
