Today, we are finally beginning to find out. 1________ First, space exploration answers some of our deepest questions. 2________ Are we alone in the universe? How did the earth begin? By sending probes and telescopes into space, scientists are slowly finding answers that early humans could only dream of. Second, space technology improves life on the earth. 3________ Weather satellites warn us about coming storms; GPS guides us when we drive; and materials developed for spacecraft are now used in everyday products such as sports shoes and phones. Third, space exploration brings nations together. 4________ Astronauts from different countries have worked side by side on the International Space Station. When they look down at the earth, they see no borders — only one planet, home to all of us. Of course, space exploration is expensive and sometimes dangerous. 5________ But as one astronaut said, “If we only do the safe and cheap things, we will never learn anything new.” A. Here are some of the reasons why space exploration matters. B. Where did we come from, and where are we going? C. Many of the things we use every day began as space research. D. Space projects often involve international teamwork. E. Some people argue that the money should be spent on the earth. F. Space exploration has no connection with daily life. G. Only a few countries are able to explore space. 五、阅读理解 （一） In 2019, China's Chang'e 4 lander became the first spacecraft in history to land on the far side of the moon. The far side is the part of the moon that never faces the earth, so it had never been visited before. Landing there was far from easy. Because the far side cannot be seen from the earth, scientists could not send signals directly to the lander. China had solved this problem two months earlier by placing a relay satellite in space, which passed signals between the earth and the moon. The lander carried a small rover, named Yutu 2, which means “Jade Rabbit 2”. Yutu 2 has been moving slowly across the surface, studying the rocks and the soil. It has already sent back valuable information about what lies under the moon's surface. By 2020, it had travelled more than 500 metres — a long way, at a speed of only about two hundred metres a year. Why is the far side so interesting? Scientists say that it is very different from the side we can see. Its surface is much older, and there are more craters. Studying it may help us understand how the moon, and even the earth, were formed billions of years ago. 1.What made Chang'e 4 special? A. It was the first spacecraft to land on the far side of the moon. B. It was the largest spacecraft ever built. C. It was the first spacecraft to leave the earth. D. It carried the first person to the moon. 2.What problem did scientists face in landing on the far side? A. The surface was too hot. B. They could not send signals directly to the lander. C. There was no place to land. D. The spacecraft was too heavy. 3.What is Yutu 2? A. A relay satellite. B. A small rover on the moon. C. A rocket for space travel. D. A camera on the earth. 4.How far had Yutu 2 travelled by 2020? A. More than 500 metres. B. More than 5,000 metres. C. About 200 metres. D. About 20 kilometres. 5.Why do scientists want to study the far side? A. It is closer to the earth. B. Its older surface may explain how the moon and earth were formed. C. It is where the Jade Rabbit lives. D. It is easier to reach than the near side. （二） Mars has been called the most likely place for human beings to live besides the earth. It is smaller than the earth, but it has seasons, deserts, mountains and even frozen water at its poles. For years, scientists have been asking: could people really live there one day? The problems are enormous. First, Mars has almost no air for people to breathe. Its atmosphere is more than 95% carbon dioxide, and the pressure is less than 1% of that on the earth. Humans would need special suits or sealed buildings just to step outside. Second, Mars is very cold. The average temperature is about minus 60 degrees Celsius. Third, it is very far away — a journey from the earth takes about seven months, and the planets are only close enough for such a trip every two years. Yet many scientists believe a human mission is possible within a few decades. Robotic explorers are already there, studying the soil, the weather and possible sources of water. In several countries, engineers are designing rockets and living units for future Mars travellers. Should we go? That is a question everyone must answer for themselves. But as one space scientist put it, “Every time people said that something was impossible, someone went ahead and did it. That is how we got out of the caves and onto the moon.” 6.What do we know about Mars? A. It is larger than the earth. B. It has seasons, deserts and frozen water at its poles. C. It has an atmosphere just like the earth's. D. It has no mountains at all. 7.Why would humans need special suits on Mars? A. Because there is almost no air to breathe. B. Because the sun is too bright. C. Because the surface is covered in water. D. Because animals live there. 8.What is the average temperature on Mars? A. About 60 degrees Celsius. B. About minus 60 degrees Celsius. C. About 0 degrees Celsius. D. About minus 6 degrees Celsius. 9.How long does a journey from the earth to Mars take? A. About seven weeks. B. About seven months. C. About seven years. D. About seven days. 10.What does the space scientist's words suggest? A. People should never take risks. B. Impossible things can be achieved with courage and effort. C. Mars will never be visited by humans. D. Only robots can explore space. 习题答案解析 一、单词拼写 1. “探索”，exploration 作名词，space exploration 意为“太空探索”，是固定搭配，故填 exploration。 2. “宇航员”，astronaut 作可数名词，被 The 修饰，谓语 spent 用过去式，指宇航员在空间站工作六个月，故填 astronaut。 3. “发射”，launch 作动词，was 后接过去分词构成被动语态，指火箭于今晨九点成功发射，故填 launched。 4. “进入”，enter 作动词，will 后接动词原形，enter the orbit 意为“进入轨道”，故填 enter。 5. “大气层”，atmosphere 作名词，被 The 修饰，指科学家正在研究火星的大气层，故填 atmosphere。 6. “探测器”，probe 作可数名词，被 The 修饰，谓语 sent 用过去式，指探测器传回了行星的照片，故填 probe。 7. “任务”，mission 作可数名词，被 The space 修饰，谓语 lasted 用过去式，故填 mission。 8. “环境”，environment 作名词，被 The 修饰，指我们应该保护地球的环境，故填 environment。 9. “遥远的”，distant 作形容词，作表语，指望远镜让我们看到非常遥远的恒星，故填 distant。 10. “成功”，success 作不可数名词，被 The 修饰，指太空计划的成功，故填 success。 二、词性转化 1. explore 动词“探索”，名词形式是 exploration，意为“探索；勘探”，如：Space exploration costs a lot of money.（太空探索耗资巨大。） 2. discover 动词“发现”，名词形式是 discovery，意为“发现”，如：The discovery changed our understanding of the universe.（这一发现改变了我们对宇宙的认识。） 3. science 名词“科学”，表示“科学家”用 scientist，如：Scientists are studying the surface of Mars.（科学家们正在研究火星表面。） 4. achieve 动词“取得”，名词形式是 achievement，意为“成就”，如：Landing on the moon was a great achievement.（登上月球是伟大的成就。） 5. succeed 动词“成功”，形容词形式是 successful，意为“成功的”，如：The launch was completely successful.（这次发射完全成功。） 6. graduate 动词“毕业”，名词形式是 graduate/graduation，意为“毕业生；毕业”，如：He is a science graduate from a famous university.（他是一所著名大学的理科毕业生。） 7. independently 副词“独立地”，形容词形式是 independent，意为“独立的”，如：China has become an independent force in space.（中国已成为太空领域的一支独立力量。） 8. technical 形容词“技术的”，名词形式是 technology，意为“技术”，如：Modern technology makes space travel possible.（现代技术让太空旅行成为可能。） 9. universe 名词“宇宙”，形容词形式是 universal，意为“宇宙的；普遍的”，如：Gravity is a universal law.（万有引力是一条普遍定律。） 10. assist 动词“帮助”，名词形式是 assistance，意为“帮助；援助”，如：The team worked without any outside assistance.（这个团队没有任何外部援助地开展工作。） 三、选词填空 1. “发射”，launch 作名词，the rocket launch 意为“火箭发射”，被 The 修饰，用单数，故填 launch。 2. “技术”，technology 作不可数名词，作句子主语，被 Modern 修饰，谓语 has made 用单数，故填 technology。 3. “大气层”，atmosphere 作名词，被 The Earth's 修饰，谓语 protects 用单数，指大气层保护我们免受太阳有害射线，故填 atmosphere。 4. “成就”，achievement 作可数名词，one of the greatest 后接复数名词，故填 achievements。 5. “轨道”，orbit 作名词，in orbit 意为“在轨道上”，是固定搭配，故填 orbit。 6. “任务；计划”，mission 作可数名词，China's space mission 意为“中国的太空任务”，被 China's space 修饰，用单数，故填 mission。 7. “宇航员”，astronaut 作可数名词，被 The 修饰，谓语 was trained 用单数，故填 astronaut。 8. “遥远的”，distant 作形容词，修饰名词 stars，指来自遥远恒星的光，故填 distant。 四、七选五 1.
