Do you know how the spaceships work during the flight? Discuss in groups for a while, and then report to the class.T: Do you have any ideas, Group 1?T: Group 2?T: Good ideas! Which group is right? Lets keep it as a secret. After listening to 1a, you will get the answer.Step 2: Let the Ss read the statements in 1b, tick the possibilities.T: Maybe you know much about computers. Try to predict what computers can do to spaceships. Tick what you think may happen. Discuss how the spaceships work during the flight.S1: We think the spaceships are controlled by the astronauts.S2: We dont agree. We think the spaceships are controlled by computers.S3: Read the statements in 1b and tick the possibilities.如果学生不能用英语来讨论飞船是怎样工作的，也可以用汉语来表达。让学生根据已有经验来预测未知的领域有助于激发他们听的欲望，并更专注于特定的内容。3While-listening(4mins)Individual workLet the Ss listen to 1a and get the answers to discussion and prediction.
