教学过程

Step 1 Lead-in

Revision

Revise the Strange Happenings in My Town by completing the information in the form.

Then get some students to retell the strange happenings.

Show the students a picture and get them to guess what it is with must, might or can’t.

UFO: unidentified flying object (不明飞行物，飞碟)

Any object that flies and cannot initially(最初)be identified as an airplane, helicopter, blimp, balloon, kite, or any other object that normally flies, is a UFO. Many flying objects that are listed as a UFO can later be identified as an object made on Earth, then they can be called an IFO, or identified flying object.

Show two pictures of UFO and an alien to the students and get them to talk about  them.

Have you heard about UFO or aliens?

How do you think of them?

Do you like them?

Step 2 Work on 1a

Look at the pictures. Then use the words in the box to write a sentence about each picture.

a. A UFO is landing.

b. ______________

c. ______________

Check the answers.

An alien is running after a man.

The man is looking back while running.

Discussion

Get the students to talk about the three pictures.

If these three pictures were from the same story, which one do you think might come first? Why?

A: I think Picture B might come first because the man in Picture C is running, and in Picture B, we can see an alien is running after him.

B: I don’t agree. I think Picture A must come first. In Picture A, we can see a UFO landing. The UFO has to land before the alien come out and run after the man.

Step 3 Listening

1. Listen and number the pictures [1-3] in 1a. Then write two or three sentences to finish the story.

Check the answers one by one.

The answers are: 2 3 1  

2. The ending of the story: A woman is filming with a camera. They are making a movie.

Listen again. Complete the sentences.

Check the answers one by one.

The answers are: (1) late for work; running for exercise

(2) a plane; a UFO 

(3) an alien; dreaming 

(4) from the TV news; making a movie.

Step 4 Pair work

Role-play a conversation between the man and the woman.

A: Why do you think the man is running?

B: He could be running for exercise.

A: No, he’s wearing a suit. He might be running to catch a bus to work.

A: Why do you think the man looks scared?

B: There might be something strange.
