While students write sentences, move around and offer language support if they need.Call different students to say their sentences and ask other students to check whether they made right inferences.Step 2 Warm-up（About 4 minutes）T: Boys and girls, I know most of you must be interested in mysteries. There are many unexplained mysteries in the world, like the original crop circles, the Pyramids of Egypt, Stonehenge, UFOs and Area 51 and so on. Next, look at the pictures and tell me what they are.Show the picture of UFO and an alien and have a free talk with a student. T: Look! Whats this? S1: Its an UFO. T: Yes, What do you think of it?S1: I think its very mysterious. T: Yes, its a mysterious thing. And this is an alien. How does it look?S1: It looks very ugly and strange.T: Yes. UFOs and aliens are mysterious for us. We hardly know them. So we should work hard to explore the secrets of them in the future.Step 3 Presentation（About 6 minutes）Present some pictures and have a free talk with students.T: (Point to Picture 1) Whats the bear doing?S1: Is it playing basketball?T: It might/could be playing basketball.Have students talk about other pictures with their partners according to the example.

Lets look at another picture. (Present the picture b in 1a) Why is the man running?S2: Wow, an alien is running after him. T: Yes, He is running because he is afraid of the alien. Next, we look at the pictures in 1a and write sentences to describe them with the words in the box.Have students write sentences by themselves, and then call three students to say their sentences. Check answers with students.Answer: a. A UFO is landing. b. An alien is running after the man. c. A man is running.Step 4 Listen and number（About 5 minutes）Point the three pictures in 1a and say, you will hear a conversation about these pictures. As you listen, write a number in the box in the left corner of each picture to show the order of the events.Point out the sample answer in the box of the third picture. Say, you will hear the man is running first. Play the recording the first time. Students listen and number the pictures. Play the recording again. Check the answers with students.T: Do you really think there are aliens? Do you think what will happen? Please write two or three sentences in the box of 1b to finish the story.Encourage students to think and write two or three sentences individually to finish the story.Call different students to share their endings of the story with other students.Step 5 Listen and complete（About 7 minutes）T: Different people make different inferences according to what they saw. Next, youll listen to the same recording again and complete each sentence.Have students look through to the chart in 1c and know about what to do. Play the recording twice and ask students to complete the sentences. Then play the tape again and show the answers so that students can check the spelling and other details of their answers.Step 6 Pairwork（About 5 minutes）Invite a pair of students to read the sample conversation in the box of 1d to the class.Have students make up conversations in pairs using information in 1c. As the pairs work together, walk around the classroom listening to some pairs and offering help as needed.

T: No, cant you see it looks terrible? It must be hungry. Have students talk about the other pictures with their partners. Make sure they can make inferences using “must”, “might”, “could” and “cant”. Then call several pairs to share their conversation with the class.Sample conversation1:A: Why do you think the girl is crying?B: She could be crying for the failing of the exam.A: No, her pet dog died.
