P30Walking does need a bit of practice now that gravity has changed. P31We watched, amazed as fire broke out on the outside of the spaceship the earth’s gravity increased. P312 Ability goalsa Discuss the three ways in which gravity changed on the moon. and some information about black holes.b. Discuss the questions about the passage:How did gravity change on the moon?What does a black hole look like?What will happen if an object is near the black hole?Teach the Ss to read passages with feeling.3 Learning ability goalsEnable the Ss to get to know about gravity and black holes.Teaching important pointsTalk about gravity and black holes.Teaching difficult pointsa.

Turn to Page66, read it quickly and try to find the answers to the questions.Questions: 1.Can a black hole be seen? How do you know it’s a black hole?2.What happened to the spaceship from the beginning to the end?Check the answer with the whole class.Answers: 1.No, it can’t be seen. You can see things disappear into what appears to be an empty space.2.At first the lights on the spaceship went out and the computer stopped working.Then the spaceship jumped and began to move around the edge of the outside of thehole.As the spaceship moved around the hole, it began to go faster and faster.But then the spaceship jumped again, and it moved sideways from the black hole.It began to increase its speed until it seemed to be going as fast as light.At last the spaceship slowed down and the computer started working again.T: Now talk about the form on Page 67 with your partners.(A few minutes later,)T: All right.We’ll talk about the answers.Ask several students to answer them one by one, and then show suggested answers.Suggested answers:Step IV Extra-readingHere is a supplementary reading material on the screen, a passage about black holes. Read it carefully and then do some comprehension exercises with their partners.T: Till now, we have learned two passages about gravity and black holes. Here is a supplementary reading material on the screen. Read it carefully and prepare to do some reading comprehension exercises with your partners.Questions: 1.What’s a black hole?2.Why is it called black hole?3.What is called the singularity?4.What is called the event horizon?What is a Black Hole?A black hole is what remains when a massive star dies.If you have read How Stars Work, then you know that a star is a huge, amazing fusion reactor. Because stars are so massive and made out of gas, there is an intense gravitational field that is always trying to collapse the star. The fusion reactions happening in the core are like a giant fusion bomb that is trying to explode the star. The balance between the gravitational forces and the explosive forces is what defines the size of the star.As the star dies, the nuclear fusion reactions stop because the fuel for these reactions gets burned up. At the same time, the star's gravity pulls material inward and compresses the core. As the core compresses, it heats up and eventually creates a supernova explosion in which the material and radiation blasts out into space. What remains is the highly compressed, and extremely massive core.The core's gravity is so strong that even lightescape.sinks through the fabric of space-time, creating a hole space-time -- this is why the object is called a black hole.The core becomes the central part of the black hole called the singularity.The opening of the hole is called the event horizon.You can think of the event horizon as the mouth of the black hole. Once something passes the event horizon, itis gone for good. Once inside the event horizon, all "events" (points in space-time) stop, and nothing (even light) can escape. The radius of the event horizon is called the Schwarzschild radius, named after astronomer Karl Schwarzschild, whose work led to the theory of black holes. Suggested answers:1. A black hole is what remains when a massive star dies.Photo courtesy NASAArtist concept of a black hole: The arrows show the paths of objects in and around the opening of theblack hole.2. Because the core's gravity is so strong, the core sinks through the fabric of space-time, creatinga hole in space-time -- this is why the object is called a black hole.3.The core becomes the central part of the black hole called the singularity.4.The opening of the hole is called the event horizon.Step V HomeworkCollect passages about gravity.Prepare for speaking。

人教英语必修三Unit4Astronomythescienceofthestar教案3
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.

Whether we can land on Mars depends on the development of science and technology. Man has known a little about Mars: there is almost no oxygen on Mars and it might be about 50 degrees above zero at noon and 100 degrees below zero at night，which prevents us from living there. Now that Mars are quite different from our earth，if we are to go to Mars one day，we should have to take along our own oxygen，food，clothing and shelter. Although it seems to be only a dream to land on Mars，scientists are certain that man willland on Mars in time.Ⅱ. 能力培养和提升A“Have a nice day！” may be a pleasant gesture or a meaningless expression. When my friend Maxie says “Have a nice day” with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well.“Have a nice day.

The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day.

While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.【语篇解读】这是一篇说明文。
