Why does the earth have life while the other planets don't ？For one thing ，the earth is just the right temperature. As the third planet from the sun ，the earth seems to be just the right distance away. The planets which are closer to the sun are so hot that their surfaces bake(烘烤)in the sun. The farthest planets are cold balls.When the earth developed ——which scientists believe may have happened about 4 billion years ago ——many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth ，and it is quite a bit cooler. But it is not too cold for humans. On some days ，the temperatures are as low as a winter day in the northern United States. If you wore a special spacesuit ，you could walk around on Mars. You would have to bring your own air to breathe ，because the air on Mars is too thin to breathe.Mars has the largest volcano(火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected(未预料到的) sight on Mars is dried-up river beds. Scientists believe that Mars was once much better than itis now. Does this mean there could have been living things on Mars ？Scientists are not sure ，but there has been no sign so far.21. Which of the following is NOT the reason that the earth has life? A. The earth is just the right temperature.B. The volcanoes on the earth are lower than those on Mars.C. There is oxygen in the atmosphere of the earth.D. The earth seems to be just the right distance away from the sun.22. The underlined phrase “the third planet” in the first paragraph refers to_______. A. the Sun B. the Moon C. the EarthD. the Mars23. Which of the following about the Mars is NOT true? A. There could have been living things on Mars. B. Mars has the largest volcano in the solar system. C. There is almost no oxygen in the air on Mars.D. Mars is smaller than the earth ，and it is quite a bit cooler.BDamage to Ozone layer Gets WorseIn the middle of winter, when snow is falling in many parts of the United States, scientists have sounded a warning to people who plan to spend many hours in the sun this summer. The warning is: The sun’s summertime rays are more d angerous than once thought.A team of scientists from 80 nations recently reported to the United Nations that a layer of ozone (臭氧层) in the atmosphere, which protects humans from harmful levels of ultraviolet （紫外线） radiation, will be thinner over the United States this summer. The thinner layer allows more ultraviolet rays from the sun to reach Earth. The extra amount of ultraviolet radiation could cause an increase in the number of cases of skin cancer.Scientists first became concerned about the ozone layer in the mid-1980s when a hole was discovered in the layer above Antarctica during the winter. The hole was caused by chemicals used in refrigerators and air conditioners. When these chemicals are sent out into the atmosphere, they produce gases that destroy the ozone.Concern about the protective ozone layer rose more recently when data(数据) from satellites and ground stations showed that ozone levels were dropping over areas other than Antarctica. Low ozone levels were recorded in the spring and summer over the United States and over other populated areas in the world.Although many countries have already begun stopping the use of ozone destroying chemicals, the new findings are expected to advance the timetable for a total ban(禁止) of the chemicals.24. The scientists have observed the ozone layer ________.A. since 1980B. since last winterC. for more than 20 yearsD. for about one year25. The ozone layer in the atmosphere can ________.A. do a lot of good to human beings in many ways.B. protect humans from diseases caused by bad weather.C. do a lot of harm to human beings in the summer-time.D. protect humans from harmful levels of ultraviolet radiation.26. Scientists first found that there was a hole in the ozone layer ________.A. above Arctic during the winter in the mid-1980sB. above Antarctica during the winter in the mid-1980sC. over somewhere in the north of the equator in 1980D. over the U.S.A in the summertime in the mid-1980s27. The damage to the ozone layer was caused by ________.A. the changeable weatherB. ozone-destroying chemicalsC. chemicals from refrigeratorsD. chemicals from air conditioners四、课文语法填空（共10小题；每小题1.5分，满分15分）No one knows ___28__ (exact) how the earth began, as it ___29__ (happen) so long ago. However, according to a widely __30__ (accept) theory, the universe began with a “Big Bang” that threw matter in all ___31__ (direction). After that, atoms began to form and combine to create stars and other bodies.For several billion years after the “Big Bang”, t he earth was still just a cloud of dust. What it was to become was uncertain until between 4.5 and 3.8 billion years ago when the dust settled into __32__ solid globe. The earth became so violent that it was not clear __33__ the shape would last or not. It exploded loudly with fire and rock. They were in time __34___ (produce) carbon, nitrogen, water vapour and other gases, which were to make the earth’s atmosphere. ___35_ is even more important is that as the earth cooled down, water began to appear on its surface.What many scientists believe is that the continued presence of water allowed the earth to dissolve __36__ (harm) gases and acids into the oceans and seas. This produced a chain reaction, which made __37__ possible for life to develop.五、书面表达（满分25分）假设你是李华，最近从报纸上得知2017年敦煌文博会“Silk Road (Dunhuang) International Cultural Expo” 将于9月举行，组委会现面向全社会招募志愿者，要求英语口语流利，了解丝路文化及国外习俗等。

Discussion and cooperative learningTeaching aids教具准备1 A computer2 A projectorTeaching procedures & ways教学过程与方式Step I RevisionAsk some of the Ss to read his / her passage about gravity.One possible passage:Sir Isaac Newton: The Universal Law of GravitationThere is a popular story that Newton was sitting under an appletree, an apple fell on his head, and he suddenly thought of theUniversal Law of Gravitation. As in all such legends, this isalmost certainly not true in its details, but the story containselements of what actually happened.What Really Happened with theApple?Probably the more correct version of the story is that Newton,upon observing an apple fall from a tree, began to think alongthe following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "accleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree.Sir Isaac's Most Excellent IdeaNow came Newton's truly brilliant insight: if the force of gravity reaches to the top of the highest tree, might it not reach even further; in particular, might it not reach all the way to the orbit of the Moon! Then, the orbit of the Moon about the Earth could be a consequence of the gravitational force, because the acceleration due to gravity could change the velocity of the Moon in just such a way that it followed an orbit around the earth.This can be illustrated with the thought experiment shown in the following figure. Suppose we fire a cannon horizontally from a high mountain; the projectile will eventually fall to earth, as indicated by the shortest trajectory in the figure, because of the gravitational force directed toward the center of the Earth and the associated acceleration. (Remember that an acceleration is a change in velocity and that velocity is a vector, so it has both a magnitude and a direction. Thus, an acceleration occurs if either or both the magnitude and the direction of the velocity change.)But as we increase the muzzle velocity for our imaginary cannon, the projectile will travel further and further before returning to earth. Finally, Newton reasoned that if the cannon projected the cannon ball with exactly the right velocity, the projectile would travel completely around the Earth, always falling in the gravitational field but never reaching the Earth, which is curving away at the same rate that the projectile falls. That is, the cannon ball would have been put into orbit around the Earth. Newton concluded that the orbit of the Moon was of exactly the same nature: the Moon continuously "fell" in its path around the Earth because of the acceleration due to gravity, thus producing its orbit.By such reasoning, Newton came to the conclusion that any two objects in the Universe exert gravitational attraction on each other, with the force having a universal form:The constant of proportionality G is known as the universal gravitational constant. It is termed a "universal constant" because it is thought to be the same at all places and all times, and thus universally characterizes the intrinsic strength of the gravitational force.Step II PresentationT: Do you remember the conversation between Li Yanping and Professor Wallis?S1: Yes.T: We all know that space walk is difficult and dangerous. What should an astronaut take with him? S2: oxygen can.S3: spacesuit.S4: gravity boots.S5: water system.S6: special food.S7: special ropes.T: Great! Do you know the usage of them? Now discuss them with your partner according to the form on Page31. You can refer to our listening material on Page65.When Ss discuss. Teacher walk around the classroom to give them some help.Step III Speaking (Page31)(After a few minutes.)T: Have you finished? Now speak one or two sentences for each equipment you should take.Sa: I will take water with me in my spacesuit in order to warm or cool me if it’s too cold or too hot. Sb: I will take oxygen can on my back in order to help me breathe oxygen in space.Sc: I’ll wear spacesuit. t can protect me from many dangers. It can carry many necessary things in or on it.Sd: I’ll take space buggy in order to travel on the moon.Se: I’ll take a rope to tie me to the spaceship, or I’ll fly away.Sf: I’ll take special food so that I can eat easily, because the food will float in space.Sg: I’ll wear special sunglasses in order to protect my eyes.Sh:I’ll take space camera in order to take photos.T: Wonderful! Anything else?Si: I’ll wear space boots in order to walk there.T: Very good. You’ve done an excellent job! Do you know how to fill in the form now?Ss: Yes.T: Now look at the screen and check your answer.Sample answer:Step IV Talking (Page62)The task asks the students to work in pairs and give a friend a number of “does” and “don’ts” for going into space. They need to make suggestions using the phrases that they have been given to help them. When they have worked out the advice they can write the suggestions down and read them out to the class.Show the useful expressionsPlease look at/ listen to…Please check that…You need…Please pay attention to…Don’t forget to…You’d better…Make sure you…Watch out for…You mustn’t…T: Now discuss it in pairs. Then I will ask some pairs to read out their instructions.Sample dialogue:S1: I’m going to visit a comet. I’m leaving tomorrow.S2: How exciting! Please check that you have got the correct sort of spacesuit. You need the kind that will keep you warm if it’s too cold.S1: Of course!S2: Make sure you know all the safety rules. It’s not safe to stand on a comet or get too close.There is always a strong wind in space.S1: I won’t leave the spaceship except that I take photos.S2: Photos? Just think of the dust in the air. It will make taking photos very difficult.S1: Well, I’ll take some anyway.S2: Watch out for the space wind! It can be very dangerous.S1: Yes, I know that.S2: Don’t forget to watch the time as you leave the earth. Please pay attention to everything your space guide says. Don’t go off on your own. Look at your temperature on your spacesuit all the time. If it’s too low you need to warm it up and if it’s too high you need to cool it down. Anyway, have a good trip!S1: Thank you. I will.Step V Speaking Task (Page67)The purpose of this task is to use the information the students have gained from the listening text and reading passage in a new situation. They are going to interview the astronomer in our story, Li Yanping, for a newspaper. So in pairs the need to work out some questions to ask him. Each of the pairs needs to think of three different questions. And try to find the answers.Questions and answers:1.What was the most unexpected thing you found out about black holes?The black hole threw out material as well as ate objects.2.How did you know you had got close to a black hole?You can see things disappear into what appears to be an empty space.
