Teaching and learning steps

S2:The water is very clean and we can see some little stones and fish in the river.
S3:The mountains are very green.
S4The air is very fresh.
T: Well, you did very well. It’s very beautiful and we all like it ,right?
Ss: Yes.
Let’s look at another group of pictures, what do you think of them?
S1: The water is very dirty.
S2:The air is polluted.
S3:Many trees are cut down.
S4:We can see lots of fish and birds died because of pollution.
T:Can you tell me who caused this?
Ss: Human beings.
T:What should we do to bring back green hills and clean water?
Ss:…
T: Today we’ll learn some words about environmental protection.Now let’s learn the words and phrases of Unit 13. Open your books to Page 168.
Look at the new words and phrases in this unit.
Step 2　Learn to read the words on P97-102
1. Ask the students to read the words by themselves using the phonetics, underline the difficult words.
2. Encourage the students to read the difficult words with their partners.
3. Get two or three middle-level students to read all the words, the others listen and correct their mistakes in pronunciation. If necessary, the teacher helps them.
4. Read after the tape, imitate the pronunciation.
5.The students read aloud to memorize the words. (The teacher walks around to see whether students have any questions. )
(设计意图：本环节通过学生自读—组内互读—朗读纠错—磁带跟读，达到正确熟练朗读本单元生词。音标学单词是学生学习英语的必备能力，所以要重点强调学生自读环节。在教学中要继续让学生试读单词，巩固和提高学生自学单词的能力，培养学生良好的学习习惯。首先学生自己根据音标字读单词，并标出试读难点。接着组内读给同伴听，解决遇到的发音问题。然后教师检查学生朗读，及时纠正错音。最后让学生跟录音读。单词的学习坚持从个体—同伴—小组—整体的原则，培养学生自主学习和小组互助学习的能力,以保证所有学生都能熟练读出单词，语音纯正，发音准确。）
