1、Passage 1In 1901, H.G.Wells, an English writer, wrote a book describing a trip to the moon. When the explorers landed on the moon, they discovered that the moon was full of underground cities. They expressed their surprise to the“ moon people " they met. In turn, the“ moon people ”surprise. “Wh

2、y," they asked,“are you traveling to outer space when you don' t evenspace? ”H.G.Wells could only imagine travel to the moon. In 1969, human beings really did land on the moon. People today know that there are no underground cities on the moon. However, the question that the “moonpeople &qu

3、ot;asked is still an interesting one. A growing number of scientists are seriously thinking about jt.Underground systems are alreadyin place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas. The “Channel "a tu

4、nnel connecting England and France, is now complete.But what about underground cities? Japan' Kaisei Corporation is designing a network of underground systems, called “Alice Cities ” . The designers imagine using surface space for pub parks and using underground space for flats, offices, shoppin

5、g, and so on. A solar dome would cover the whole city.Supporters of underground development say that building down rather than building up is a good way to use the earth ' s space. The space, they say, can be used for farms, parks, gardens, and wilderness. H.G.Wells “moon people “ would agree. W

10、Earth like a light blanket. The Earth is shaped like a sphere, or a ball. It is 25,000 miles around! It would take more than a year to walk around the whole planet. A spaceship can fly around the widest part of the sphere in only 90 minutes.Even though spaceshipshave traveled to the Moon, people can

11、not visit the Moon without special suits. The Moon has no air or water. Plants and animals can' t live there either. Asfirst landed on the Moon in 1969. After that, there were six more trips to the Moon. They brought back Moon rocks, which scientists are still studying. There are holes, or crate

12、rs, all over the Moon surface. Scientists believe that meteorite?s 陨石）smashed into the Moon millions of years ago and formed the craters.The Sun is the closest star to Earth. A star is a hot ball of burning gas. The Sun looks very big because it is so close. But the Sun is just a medium-sized star.

13、Billions of far -away stars are much bigger than our Sun. The burning gases from the Sun are so hot that they warm the Earth from 93 million miles away! Even though the Sun is always shining, the night here on Earth is dark. That because the Earth rotates, or turns around, every 24 hours. During the

14、 day, the Earth faces the Sun.Then we see light. During the night, the Earth turns away from the Sun. Then it faces the darkness of space.Each day we learn more about the Earth, the Moon and the Sun.1.When we look at the Earth from outer space, the color we see most is blue because.A. most of the Ea

26、oes around and around Earth in a never ending journey called the water cyclef环）。The sun heats up lakes, oceans, and other wet places on Earth. When the water gets warm enough, it changes into vapour. Plants also give off lots of water vapour. Some of this water vapour cools off high in the sky and b

27、ecomes clouds. Then it falls back to Earth in a new place as rain or snow. This cycle happens over and over again.The ground can absorb water like a sponge （海绵）。 If you could see this groundwater, it wouldn ' t look like a lake or river. The groundwater is mixed in with the rocks and sand that l

32、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 programs come to US through s

33、atellites.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 kilometers above the equator.Sometimes we can see a satellite in the sky and it seems to stay i

34、n the same place.This is because it is moving around the world at ,11000 kilometers an hour exactly the same speed that the earth rotates.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

35、 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 10-12 years.Satellites which are broken are sometimes repaired by astron

36、auts or sometimes brought back to Earth to be repaired.Oft envery 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.1 .Which of the following is NOT done by satellites a

37、ccording to the passage?A.Sending information for weather forecast.B.Taking photographs of the Earth.C.Sending TV pictures.D.Providing food for airplane pilots.2 .What' s the speed the earth rotates at?A.35,880 kilometers per hour.

38、0,000 kilometers per hour3 .Why does the satellite move around the world at the same speed as the Earth rotates?A.In order to take photographs.B.In order to stay in a certain position in the orbit.C.In order to move away from its orbit.D.In order to send television pictures.4 .What does the underlin

39、ed word“This ” in the 3rd paragraph refer to?A.A satellite. B.A little rocket.C.A satellite seems to stay in the same place in the sky.D.The satellite puts the rockets in the right position.5 .Which is true of satellites?A.A satellite usually works for about 10-12 years.B.Every time a satellite gets

40、 broken it is brought back to the Earth to be repaired.C.A broken satellite is never left in space.D.They often crash into each other.1-5 DCBCAPassage 6If your cellphone suddenly stops working, don't blame the service provider. The malfunction（故障）might have been caused by something bigger a sola

41、r storm. Experts expect that the earth will see more solar activities in the near future. The malfunction of electronic devices is just one of the effects.Sunspots依阳黑子）serve as an indicator of the sun's activity. For the past two years, sunspots have mostly been missing. Their absence, the longe

42、st in nearly 100 years, has taken even sun watchers by surprise.When the number of sunspots drops at the end of each 11-year cycle, solar storms die down and all become much calmer. This “solar minimum “ doesn't last lonyeWjthimapots and solar storms begin to build toward a new crescendo,_the ne

43、xt solar maximum.What's special about this latest cycle is that the sun is having trouble starting the next solar cycle. The sun began to calm down in late 2007, so no one expected many sunspots in 2008. They should return in 2010. Scientists have predicted that the next solar cycle could be the

44、 most active on record: more sunspots and more solar storms.However, sunspots are mostly missing now.Since the earth is in close contact with the sun, strong solar activities can bring trouble to our life. People of the 21st century rely on high-tech systems for the basics of daily life. Air travel

45、and radio communications can be affected by strong solar activities. A big solar storm could cause 20 times more economic damage than Hurricane Katrina.What the sun will do next is beyond our ability to predict. Most astronomersthink that the solar cycle will go on but at low level. However, there i

46、s also evidence that the sun is losing its ability to produce sunspots. By 2015, they could be gone altogether.1. The sun watchers feel surprised at.A. the longest sunspots' absenceB. the largest sunspot numberC. the malfunction of electronic devices D. the serious damage by sunspots2. What does

47、 the underlined word “crescendo " in Paragraph 3 most probably mean?A. small numberB. high levelC. usual cycleD. fresh start3. We can infer that in the past two years.A. solar activities have brought much trouble to our lifeB. the number of sunspots has increased to a large extentC. the solar m

48、inimum took the place of the solar maximumD. our cellphones have seldom been interrupted by the solar storm4. Which statement does the text lead you to believe?A. Solar activities do no harm to our daily life.B. Hurricane Katrina is also a type of solar storms.C. It's difficult to predict sunspo

49、ts.D. From now on there're no sunspots.【答案】ABDC地球与太空Passage 7Space is where our future is trips to the Moon, Mars and beyond. Most people would think that aside from comets（彗星）and stars, there is little else out there. But, since our space journey started we have left so much trash （垃圾） there th

50、at scientists are now concerned that if we don't clean it up, we may all be in great danger.The first piece of spacejunk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth

51、without any results, scientists became increasingly comfortable abandoning （抛 弃）things that no longer served any useful purpose in space.It is said that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces o

52、f paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.The major problem with the space trash is that it may hit working satellites and damage traveling spaceship. Moreover, piec

53、es of junk may crash with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space s

54、huttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.1. What was the first piece of man-made space trash?A. A camera. B. A tool kit. C. A fuel tank. D. A broken satellite.2. Why were scientists NOT concerned about sp

55、ace trash in the beginning?A. It no longer served any useful purpose.B.It was millions of miles awayfrom the Earth.C. It did not cause any problems.D.It was regarded assimilar to comets and stars.3. Which of the following statements is true about space junk?A. It is huge, heavy machines.Bit never ch

56、angesposition.C. It floats slowly around the Earth.D. It may cause problemsfor space shuttles.4. What has been done about the space trash problem?A. Scientists have cleaned up most of the trash.B. Large pieces of space trash are being closely watched.C. Many nations have worked together to stop poll

57、uting space.D. Ground stations are built to help store the trash properly in space.1-4 BAADPassage 8A newly discovered planet looks just right for life as we know it, according to an international group of astronomers. Orbiting a star about 500 light-years away, the planet called Kepler-186f is abou

58、t the same size as Earth. It orbits its star at the right distance for liquid water on the surface.That is a necessary condition for life as we know it.But it is not exactly like Earth, NASA planetary scientist Elisa Quintana said.“ It s man Earth csousin. It nsot an Earth tws in. It shares the same

59、 characteristics as Earth, but their parent stars are very different,” said Quintana.Kepler-186f orbits a star that is smaller and cooler than our sun. But, writing in the journal Science, the astronomers say the planet appears to be a closer relative than most of the hundreds of others discovered so f
