教材分析

This is the fifth teaching period of this unit. As usual, the teacher should check students’ homework and offer chances for them to go over what they learned in the last period at the beginning of the class. Then lead in the new lesson.

In this period, the teaching emphasis will be put on developing students’ reading ability by reading extensively. While reading, get students learning to use some reading strategies such as skimming, scanning, and so on. As to new words and phrases, the teacher can first find those students feel most difficult and help them to understand. That’s enough here. The reading passage A VISIT TO THE MOON is a science fiction story which imagines what it might be like if an astronaut visited the moon. The purpose of science fiction writing is to combine facts with a story to make students interested and excited about travel in space. It is also to stimulate awe and wonder into the vastness of space. The astronomers in the story visit a place in space, which seems impossible for people to reach, the “black hole”. It is to help students imagine what it is like near a “black hole”. Ask students to read through the passage and try to know more about astronomy and gravity.

At the end of the class, ask students to retell the two passages.

In order to arouse students’ interest, the teacher can hold a competition among them. 教学重点

教学过程

→Step 1 Revision

1. Check the homework exercises. 2. Have some students talk about Isaac Newton, Albert Einstein and Stephen Hawking as well as their ideas on gravity. →Step 2 Warming up

Let students to brainstorm the following questions:

What country first sent people into space? How many countries have succeeded in sending people into space so far? Who first landed on the moon? Who is the first Chinese astronaut to go into space? Do you want to visit the moon? →Step 3 Reading

1. Ask students to read the passage and then describe the three ways in which gravity changed for Li Yanping and how his weight changed. 1) Write down the three ways in which gravity changed for Li Yanping.

The way gravity changed Left the earth

In space

On the moon

Suggested answers:

The way gravity changed Left the earth The gravity became very strong. In space The gravity disappeared. On the moon The gravity became very light. 2) His weight changed three times, too. Now write them down.

How his weight changed Left the earth

In space

On the moon

Suggested answers:

How his weight changed Left the earth He became very heavy. In space He had no weight and could float around like a feather. On the moon He was about one-sixth of his weight on the earth. →Step 4 Summary 1. Ask students go through the passage quickly and fill in the balnaks. 2. All students read the summary text quicjly.

→Step 5 Speaking and writing If you visited the moon, what problems would

you have ? 板书设计
