Step 1 Revision

Check the exercises about modal verbs in the workbook.

Step 2 Lead-in

Ask the students two questions about the life on Mars.

What do many people think of the life by the year 2100?

Who will do most of the work on Mars?

Step 3 Presentation 1

(1) According to the students’ answers, show them the sentences with object clauses.

People think (that) robots will do most of our work.

Many people believe (that) we will live on the planet Mars by the year 2100.

Many people are sure (that) they will have more time for their hobbies.

Then tell the students to find out the rules with the hint: From the sentences, we know (that) an object clause can be put after some _______, such as ‘think’, ‘believe’, ‘know’, or after some ___________, such as ‘sure’, ‘certain’.

(2) Ask the students to change one sentence into the negative one, and give them two items and make the students choose the better one.

Many people believe (that) we will live on the planet Mars by the year 2100.(改为否定句)

Many people don’t believe (that) we will live on the planet Mars by the year 2100.

Many people believe (that) we will not live on the planet Mars by the year 2100.

And then tell the students we always put ‘not’ before ‘think’ and ‘believe’.

Step 4 Practice 1

Ask the students to find out whether it is an object clause or not.

Step 5 Presentation 2

Another 2 questions

Can any plants grow on Mars now?

Many people are sure that some plants can produce enough water on mars, aren’t they?[来源:Z。xx。k.Com][来源:学|科|网]

Then show the students object clauses to introduce a ‘yes/no’ question.

Then tell the students to pay attention to the order and the tense.

Step 6 Practice 2

(1) Use ‘if’ or ‘whether’ to make object clauses

(2) Fill in the blanks with ‘that’, ‘if’ or ‘whether’.

3. 课堂整理

(1) 我们可以在动词后用 that来引导一个句子，替代宾语，在口语中that可省略。

(2) 我们可以在动词后用 whether\if来引导‘yes or no’ question.

若句子中有……or not时，只能用whether

(3) 句中用陈述句的语序。

4. 当堂练习

(1) Could the plants produce enough water? Daniel is not sure
