Unit 4 Space ExplorationUnit 4Section 请同学们认真完成 练案16 阅读理解Satellites are an important part of our ordinary lives.For example, the information for weather forecasts is sent by satellite.Some satellites have cameras which take photographs of the Earth to show how clouds are moving.Satellites are also used to connect our international phone calls.Computer connections of the World Wide Web and Internet also use satellites.Many of our TV programmes come to us through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometres above the equator (赤道)Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometres an hourexactly the same speed that the earth rotates (转动)A satellite must orbit the Earth with its antennae (天线) facing the earth.Sometimes, it moves away from its orbit, so there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 1012 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to the Earth to be repaired.Often, very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear power and they can crash into each other.文章大意：本文是一篇科普说明文。对各种卫星的用途、卫星工作的状态以及人们对已损坏卫星的处理办法进行了解释说明。1Which of the following is NOT done by satellites according to the passage？_D_ASending information for weather forecasts.BTaking photographs of the Earth.CSending TV pictures.DProviding food for airplane pilots.解析：细节理解题。根据第一段和第三段首句不难看出，卫星可以传递天气预报信息、拍摄地球照片、传递电视图片等，但是没说为飞行员提供食物，所以选择D项。2Why does the satellite move around the world at the same speed as the Earth rotates？_B_AIn order to take photographs.BIn order to stay in a certain position in the orbit.CIn order to move away from its orbit.DIn order to send television pictures.解析：细节理解题。根据第三段内容可以看出，卫星之所以用和地球自转相同的速度绕地球旋转，是为了保持在一定位置上。显然B项正确。3What does the underlined word “This” in the 3rd paragraph refer to？_C_AA satellite.BA little rocket.CA satellite seems to stay in the same place in the sky.DThe satellite puts the rockets in the right position.解析：代词指代题。this在此替代前文的“Sometimes we can see a satellite in the sky and it seems to stay in the same place.”故选C项。4Which is true of satellites？_A_AA satellite usually works for about 1012 years.BEvery time a satellite gets broken, it is brought back to the Earth to be repaired.CA broken satellite is never left in space.DBroken satellites often crash into each other.解析：细节理解题。根据最后一段不难看出A项正确。七选五根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。(2020新课标卷)A Few Tips for Self-AcceptanceWe all want it.to accept and love ourselves.
