Unit 4 Astronomy the science of the stars教案（人教版必修3）Period 5Using language: Extensive reading整体设计教材分析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. We will deal with two parts: A VISIT TO THE MOON in Using language on Pages 30-31 and CAUGHT BY A BLACK HOLE in Reading Task on Page 66. 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. As this reading uses the information students have gained from the listening, the teacher can first ask some students to retell the listening text to lead in the topic and then ask students to read the passage and do some comprehending exercises. While checking their answers with the whole class, deal with language problems students can’t work out by t hemselves. This is an extensive reading lesson, so the teaching steps should be simple. As to the passage CAUGHT BY A BLACK HOLE, it is to continue the above story. 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1. Develop students’ reading skills by extensive reading.2. Let students read and understand the two passages.教学难点1. Enable students to learn to use reading strategies such as skimming, scanning, and so on.2.

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 changedLeft the earthIn spaceOn the moonSuggested answers:The way gravity changedLeft 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 changedLeft the earthIn spaceOn the moonSuggested answers:How his weight changedLeft 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.2. Ask students to read the passage aloud to the tape and underline all the useful expressions or collocations in the passage. Let students read them aloud and copy them down in their exercise book after class as homework. Try to keep them in mind.Collocations: be lucky enough to do, have a chance, make a trip into space, explain sth. to sb. , the force of gravity, be off, the pull of the earth’s gravity, fall back to the earth, fall to theground, too far from the earth, as if, at all, get close to, cheer up, come on, less than, down the steps, step forward, twice as far as, fall over, a bit of, now that, after a while, get the hang of, break out, on the outside of, be pushed into→Step 4 Important language points1.
