Say your predictions. (板书生词：future，prediction)
S1：Cities will be more polluted. And there will be fewer trees.

Help the students to say：“A lot of pollution.”(板书生词：pollute v.，polluted adj.，pollution n. )
T：We must protect the environment. Will there be less pollution in the future
S2：Yes，there will.
...

Let’s discuss and think about the future. Then say some sentences.
For example：

Step 5　Work on 1a
1. Look at the picture above 1a. Please answer my questions.

2. Read the predictions in 1a. Check (√) A for agree or D for disagree.
3. Please share your answers in your group following the example in 1c.
Answers will vary.
4. Explain
结合1a中预测未来的句子，请你来总结：
(1)表示将来发生的动作或事情应该用“will+动词原形”来表达。其否定形式为：won’t+动词原形。你能写出它的疑问句式吗 Will+主语+动词原形+...
(2)当我们说“将会有……”时，我们用一般将来时态。
5. Complete the sentences according to the Chinese meanings.
(1)100年后人们将会拥有机器人。

Everything will be free.

Step 6　Work on 1b
1. T：Now listen to the recording and circle the predictions you hear in 1a.
2. Play the recording again. Check the answers with the students.
3. Listen and repeat to improve their pronunciation and intonation.
Answers：circled (in the order heard)：1，2，5，4
Step 7　Work on 1c
1. Let the students read the conversation in 1c after the teacher.
2. Then let them ask and answer questions about the predictions in 1a. Ask them to make their own conversations.
3. Let some pairs act their conversations out.
Step 8　Listening
1. Let the students read the sentences in 2a. Explain some main sentences for them. Make sure they know what to do.
2. Play the recording for the students to check the predictions they hear.
3. Play the recording again to check the answers.
Answers：2a circled：1. more　2. less　3. fewer
4. less　5. fewer　2b checked：2，5
4. Cooperative inquiry
学过2a和2b后，总结more，less，fewer的用法。
(1)fewer修饰可数名词复数，如：fewer trees，fewer people。
(2)less修饰不可数名词，如：less pollution， less milk。fewer，less表示“更少”的意思。
(3)more既可修饰可数名词复数，又可修饰不可数名词，如：more trees/cars/people，more pollution。more表示“更多”的意思。
5. Fill in the blanks using the correct forms of the words given.
(1)He spent more(much) money on books than usual.
(2)There are more(many) people in the park today than yesterday.
(3)We have more(many) students this year than last year.

(5)There will be more(many) cars and more(much) pollution.
当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. will be fewer，more　该句子为there be句型的一般将来时，“汽车”和“地铁”都是可数名词，分别用比较级fewer和more来表示“更少”和“更多”。
2. Will，be　由所给汉语意思可知本句为一般将来时，其一般疑问句形式是将will提前；be free意为“是免费的”。
3. live to be　live to be...意为“活到……”。
Ⅱ. 1. B　“for+一段时间”一般用于一般现在时或现在完成时；“in+一段时间”用于一般将来时；ago用于一般过去时；at不跟时间段。故选B。
2. B　fewer“较少的”，修饰可数名词复数；less“较少的”，修饰不可数名词。
3. C　there be句型的一般将来时态结构为there will be...或there is/are going to be...，故选C。
4. D　“Will you please not do sth. ”意为“请你不要做某事好吗 ”。故选D。
5. C　根据时间状语next year可知从句是一个一般将来时态的句子，故选C。
Step 9　Pair work
1. Tell the students to ask and answer questions about the predictions in 2a and 2b.
2. Let the students read the conversation in 2c first after the teacher.
3. Let the students talk about the predictions with the information in 2a and 2b.
4. Ask some pairs to act their conversations out.
Step 10　Summary

2. Sentences：①People will/won’t...in 100 years.
②There will/won’t be more/less/fewer...
3. Simple future tense：will+v.
