Step 1 Presentation Have a free talk with students. 1. Let students brainstorm the following questions: Who are our ancestors? Do you know what it was like before life appeared on the earth? Do you know how life began on the earth? Do you want to get more information? 2. Tell students: Today we will learn something about how life began on the earth. Turn to Page 25. Let’s come to Warming Up first.

Step 2 Warming up Let students think about the following questions and then discuss them with their partners. 1. In our solar system eight planets circle around the sun. What are they? Can you match the names with the planets? 2. What interests you in astronomy? Do you know any questions that astronomers are interested in?

Step 3 Pre-reading 1. Get students to discuss the questions with their partners. 1) The origin of life on earth is a question that interests astronomers. What do you know about it? 2) Each religion and culture has its own ideas about how life began on earth. What do you know about them? 2. Let them tell their stories. Encourage them to tell different stories. If they don’t know any, tell them some, for example, Pangu separated the sky from the earth, Pangu turned into a myriad of things, Nuwa made men, and so on.

Step 4 Reading 1. Fast reading Get students to read the passage quickly and then write down the main idea for each paragraph and the whole passage in the following chart. Let students look through the chart and then read the text silently. Three minutes later, check the answers with the whole class.
