教学过程

Step 1  Lead-in

1. Show some pictures about weather and talk about the weather. 

  sunny  cloudy  windy  snowy  foggy  rainy

2. Comic strip

  (1) Say: Hobo has some trouble. What happened to him?

  (2) Listen and answer

  ①Didn’t Eddie hear the rain?   No, he didn’t.

②Why didn’t Hobo want to go home alone?

  Because Hobo wanted Eddie to mop up the water.

③What was Hobo doing when it started to rain?

He was sleeping when it started to rain.

Check the answers with students.

(3) Analysis. 

He was sleeping when it started to rain.

过去进行时

  ①结构：was/were (not) +现在分词

  ②表示过去某一时刻正在进行的动作或过去某一阶段一直在进行的动作。

   I was doing my homework at 8:00 last night.

   What were you doing the whole morning?

(4) Listen and repeat the dialogue between Eddie and Hobo.

(5) Read the dialogue between Eddie and Hobo in roles. 

(6) Act out the dialogue between Eddie and Hobo.

Step 2  Presentation  

1. Show a picture about all kinds of natural disasters like fire, flood, earthquake, tornado etc.

2. Say: Bad weather sometimes causes (引起) natural disasters. Too much rain in a short time may cause a flood. The flood may wash away the village. Heavy rain and strong winds cause a big storm. Thunder and lightning may start a big fire. An earthquake will kill thousands of people. A coach crashed into a tree. It is not a natural disaster but an accident.

3. Ask the students to think about: What causes natural disasters / accidents, nature or people? Then tell them that nature often causes disasters while people often cause accidents.

Step 3  Part A

1. Read some newspaper headlines and tick out (√)the natural disasters.

 (Keys: 2, 5, 6, 8)

2. Analysis.

  Flood washes away village.  (a headline)

  In fact we should say：The flood washed away the village.

  In newspaper headlines, the simple present tense is used and words like a, an, the and the verb be are often left out(省略).

  lose final= lose the final         car accident= a car accident

  crash into tree= crash into a tree   wash away village= wash away the village

start big fire= start a big fire      fall from tree =fall from a tree

big storm= a big storm

Step 4  Part B

Sandy and Millie are chatting online about natural disasters and accidents.

1. Listen and Answer.

  Listen to the tape and try to find the time, place, reason and result of the fire that happened in a UK school.

2. Listen and repeat the dialogue after the tape.

3. Read the dialogue in roles.

4. Work in pairs.

  Give some information about a flood and a traffic accident. Give them some time to make up a dialogue. Show them a sample conversation.

Sample conversation:

A: Did you hear about...?

B: No. What happened?

A: ... (describe it)

B: Oh, really?

A: Yes, it was terrible... (describe it)

B: Was anyone hurt?

A: Yes/No, ...

Then choose some pairs to present their dialogue.

Step 5  Discussion

1. Discuss in groups: What can we do to protect the environment?
