1、 04 宇宙探索Passage1 Do stars only appear at night? The answer is no. Venus (金星) is the only star that can be seen in daytime. It shone at its brightest in the night sky on Feb 17 this year.Venus is the second planet from the sun. It is the second brightest natural object, behind the earths moon, in the
2、 night sky. Why is it so bright?First of all, Venus is the closest planet to the earth. It is also covered by highly reflective (反射的) clouds, which can reflect about 70 percent of the sunlight striking (照射) it, almost twice as much as the earth does. Some people call 2017 the year of Venus, because
3、the planet is at its brightest twice this year. Venus gets brighter when it goes further away from the sun, and nearer to the earth. The brightest moment happened once in February, and will happen again, during daylight, on April 30.If Venus is so bright and close to us, isnt it a better choice for
4、human exploration (探索) than Mars? It is closer to the earth than Mars and its closer to the earth in size. The closer distance to the sun means solar power (太阳能) would be easier to generate as well.However, with a temperature of about 465 on the surface, Venus is the hottest planet in our solar syst
5、em!But scientists never give up. Recently, a team of NASA and Russian scientists created new computer equipment that can stand temperatures of 480. It can work under Venus-like conditions (环境) for almost 22 days.The next step, according to the scientists, is to send a probe (探测器) to Venus by 2025.1W

On Jan 3, Change 4 became the first space probe(探测器) in history to land on the far sid
9、e of the moon, Peoples Daily reported.From Earth, we can only see one side of the moon. The other side has been a mystery. Scientists have long wondered what lies on this side of the moon.Change 4 has sent back photos of the far side of the moon. It is also used to carry out experiments, such as gro
10、wing seeds in a low-gravity(低重力) environment. The data(数据) collected from these experiments could be used to help us build a base on the moon in the future. The success of the Change 4 mission(任务) is a main achievement for Chinas space program. It marks a new stage in Chinas deep space exploration,
11、said Wu Yanhua, head of China National Space Administration.China launched(启动) its lunar(月球的) exploration program in 2004, naming it Change. Chinese scientists set three goals “orbiting(环绕运行), landing and sample(样本) returning”, referring to launching probes that could circle around the moon, touch d
12、own on its surface and bring lunar materials back to Earth.Change 4 has realized the goal of landing. The third will be achieved during the Change 5 mission, which is set to take place before the end of this year, China Daily reported.Following the success of the Change missions, Chinese scientists
13、are looking even farther into our solar system(太阳系). Chinas first Mars(火星) mission is expected to be carried out by 2020, Wu said.5What is the data collected from these experiments used to do?AHelp us build a base on the earth.BHelp us build a base on the moon.CHelp us build a base on Mars.DHelp us
14、build a base on Venus(金星).6What has Change 4 done so far?a. It has landed on the far side of the moon.b. It has taken photos of the far side of the moon.c.

16、om the passage?AChange 4 has discovered the secrets of the far side of the moon.BChinas space exploration program started 15 years ago.CChange 5 will be Chinas last lunar exploration program.DChina has not launched any space probes to Mars so far.Passage3For thousands of years, humans have explored
17、(探索) the Earth. Nowadays, we are exploring space. Astronomers (天文学家) are the modern-day explorers. Now, many astronomers are looking for new planets and new places for humans to live in the future. But where do astronomers start exploring?First of all, astronomers look for a star. Thats because our
18、own Earth moves around a star the Sun. More importantly, it is neither too far from nor too near to the Sun for heat and light. So when astronomers have found the star, they look at the planets around it. In recent years, astronomers have found nearly 400 new planets with stars. However, many of the
19、se planets are either too near to the star or too far away.However, if the planet is in good place, astronomers look for three key things: water, air and rock. Water is important because all life needs water. Humans can drink it and they can also grow plants with water. And plants produce air for hu
20、mans to breathe and food to eat. Rock on a planet is also important. Thats because there is often water under the rock.After many years of exploring, astronomers have found a planet like the Earth. Its Gliese 581g and its near a star. The astronomers think it has water and rock and the temperature i
21、s between -31 and -12. Thats cold, but not colder than Antarctica or the Arctic Circle, for example, Gliese 581g is bigger than the Earth. A year on Gliese 581g is only 37 Earth days, not 365 Earth days. But astronomers do not think these are big differences and some of them think Gliese 581g will b
22、e a new Earth. However, Gliese 581g is twenty light years from the Earth.10How do astronomers discover a new planet for humans to live on? Choose the right order.a. Astronomers look for three key things.b. Astronomers look for and find a right star.c. Astronomers look at the planets around the star.
23、Aa-b-c.Bb-a-c.Cb-c-a.Dc-a-b.11According to Paragraph 3, which of the following things is the most important?AWater.BAir.CRock.DPlants.12According to Paragraph 4, which of the following is TRUE about Gliese 581g?AGliese 581g is a star, and bigger than the Earth.BA year on Gliese 581g is shorter than
24、that on the Earth.CIt will take humans twenty years to get to Gliese 581g.DIt is colder on Gliese 581g than Antarctica or the Arctic Circle on the earth.13What does the writer mainly talk about in the passage?AWater, air and rock are important.BGliese 581g is already a new Earth.CThere are some plan
25、ets like our Earth.DAstronomers are looking for a new Earth.Passage4Mars (火星) is a planet. It is the fourth planet from the sun and is more than 200 million kilometers from it. That is a very long way. Mars is also a very long way away from the earth but sometimes you can see it clearly at night. Mo
26、st stars are white. Mars is a bit red.It is not a very big planet. It is about half the size of the earth. The earth has one moon. Mars has two moons. They are called Photos and Deimos.Long ago, the only way to study Mars was just to look at it. People with good eyes could see me things but not ever
27、ything.Later on, it was easier, because scientists had telescopes. They could see Mars more clearly. They learned much more about Mars this way.In the 20th century things got even better. First of all, we had spacecraft (宇宙飞船).They flew close to Mars and sent back information. Then, they sent spacec
28、raft to fly in orbit (轨道) around Mars. Finally, spacecraft landed on Mars. Maybe one day a man will walk on Mars.A man named Jamie works for NASA with the team sending a spacecraft to Mars. We landed a rover (探测车) on Mars he says. It is called Curiosity.What is a rover? It is a machine that looks li
29、ke a car. It can move about on Mars. It has cameras to take photos and it sends them back to the earth. It can study the rocks and air of Mars. It sends all this information back to the earth.14Which one is TRUE about the facts of the Mars?AIt is over 200 million kilometers from the sun.BWe can see
30、the Mars is a little white at night.CIt is much larger than the earth.DMars has only one moon.15What does the underlined word telescopes mean according to the passage?A放大镜B望远镜C摄像机D显微镜16Which tool can carry the man to walk on Mars?AGood eyes.BTelescopes.CSpacecraftDRover.17What cant the rover do from
31、 the last paragraph?AMove about on Mars like a car.BTake photos by cameras and send them back to the earth.CStudy the rocks and water of Mars.DSend all the information back to the earth.18The passage is mainly developed by_.Aasking some questionsBgiving some adviceCfollowing the order of timeDfollow
32、ing the order of importancePassage5 Many of us spent our childhoods dreaming of becoming astronauts. However, the fact is that only a select few will make it. But does that mean youll never get the chance to work in space? Not necessarily.In fact some of the space jobs are not only for astronauts an
33、d they all sound just as cool.One of the most interesting space jobs is “chief sniffer (嗅探员)”. NASA has already hired a chief sniffer named George Aldrich, whose job is to smell materials before they are used in spacecrafts （宇宙飞船）. Using your nose at work might sound a little strange but the job is
34、very important. Smells in a spacecraft are stronger inside of it, and once a spacecraft is launched(发射), astronauts have no way of escaping unpleasant smells”, Aldrich said. More importantly, smelling objects can help identify dangerous chemicals(化学物质) that could be harmful to astronauts health.Anot
35、her job, the “space tour guide, may seem a little ahead of its time. But now, many private companies are starting to provide space trips, and rich space lovers such as Justin Bieber and Sarah Brightman have already signed up for tours. It may not be long before space becomes one of the top travel de
36、stinations.Being a space tour guide needs rich knowledge of astronomy (天文学), astrophysics（天体物理学）, geography and history to help passengers get the most out of their journey. Tour guides also need to be excellent storytellers so that passengers can experience the true awe (惊叹) of space travel.Astrona
37、uts often spend weeks or even months in space with the same group of people, which is why a “space psychologist” is also needed to help astronauts overcome (克服) mental challenges, like feeling bored and lonely.Were crossing the boundaries (界限) between science fiction and reality(现实), said Robit Talw
38、ar, chief executive of US company Fast Future Research. Its amazing that things weve seen in the past in movies are now becoming real career opportunities.”19According to the article, George Aldrichs job at NASA is mainly about _ .Ameasuring the size and temperature of spacecraftsBkeeping astronauts
39、 safe from things that have unpleasant smellsCcheering astronauts up with excellent stories20We can infer from the article that _.Aa space tour guide needs strong social skillsBnormal people will be able to afford space travels soonCastronauts have to overcome a lot of challenges in space21What does

41、day for Chinese people. Chinas biggest and most powerful carrier rocket, the Long March 5, was successfully launched(发射)in Hainan that day.The 57-meter-tall rocket is the tallest, strongest and the most technologically difficult rocket in China. Because the Long March 5 is much bigger than other roc
42、kets in the Long March series(系列), it has been given a funny name Chubby 5.The rocket is able to carry spacecraft(宇宙飞船)to low-earth orbit(近地轨道). The spacecraft weighs up to 25 tons-nearly the weight of 16 midsize cars. The payload capacity(有效负载能力)of the Long March 5 is about 1.5 greater than any oth
43、er Chinese rocket. The Long March 5 is the third most powerful rocket in the world, following the United States Falcon Heavy and Delta Heavy.During the December launch, the Long March 5 successfully sent the Shijian 20 experimental satellite(卫星), Chinas largest and heaviest homemade satellite, into
44、orbit.Besides sending the satellite into space, the launch also tested several engineering technologies that were used to improve the rockets design. It also tested key technologies that will be used to take the Change 5 probe(探测器)to the moon.In the future, the Long March 5 will be used for Chinas f
45、ifth lunar expedition(探月), as well as to place parts of Chinas manned(载人的)space station into orbit.
