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.turn, the “moonpeople "expressed thei
2、r surprise. “Why,they asked, “areyou traveling to outer space when you don' t even use your inner space? ”H.G.Wellscould 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 t
3、hat the“ moon people " asked is still an interestingone. A growing number of scientists are seriously thinking aboutjt.Underground systems are already in place. Many cities have underground car parks. In some cities, such as Tokyo, Seoul and Montreal, there are large underground shopping areas.
4、 The “Channel "a tunnel connecting England and France, is now complete.But what about underground cities? Japan' Taisei Corporation is designing a network of underground systems, called“Alice Cities” . The designers imagine usingsurface space for public parks and using underground space for
5、 flats, offices, shopping, 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 usedfor farms, parks, gardens, and wilderness. H.G.Wells “moonpe

9、pace Travel with H.G.WellsC. Enjoy Living UndergroundD. Building Down, not Up参考答案;CBBDPassage 2From far out in space, Earth looks like a blue ball. Since water covers three-fourths of the Earth 'ssrface, blue is the color we see most. The continents look brown, like small islands floating in the
10、 huge, blue sea. White clouds cover around the 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
11、spaceships have traveled to the Moon, people cannot visit the Moon without special suits. The Moon has no air or water. Plants and animals can ' t live there either. Astronauts first landed on the Moon in 1969. After that, there were six more trips to the Moon. They brought back Moon rocks, whic
12、h scientists are still studying. There are holes, or craters, all over the Moonien'tissssbefacse Scthat meteorites (陨石)smashed into the Moon millions of years ago and formed the craters.e the E astHbexcouss, orThe Sun is the closest star to Earth. A star is a hot ball of burning gas. The Sun loo
13、ks very big because it is so close. But the Sun is just a medium-sized star. 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.
14、 That turns around, every 24 hours. During the 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.I.When we look at the Earth from outer space, the colo

We know a lot about the Earth, Moon, and Sun, but there is still more to learn.D.From outer space, the Earth looks tiny, even though it is thousands of miles around.参考答案:CADBCPassage 3Space travel is definitely bad for astronauts bones, reducing their bone dens
19、ity(密度)after only a month of weightlessness, according to French research published on Friday.Laurence Vico and his fellow workers at St Etienne University called for more research into the effects of microgravity, after their study of 15 astronauts from the Russian MIR station showed bone loss cont
20、inued throughout space flights.“ Bone loss was especially striking in four astronauts,“ the scientists reportedthe Lancet Medical Journal.They measured the bone mineral density (BMD) of bones in the forearm( 前臂)and lower leg of the astronauts who had spent one to six months in space.The BMD loss was
21、 significant in the tibia(胫骨)of the lower leg, a weight-bearing bone, but barely changed in the radius(槎骨)of the forearm. "Our results indicate the need to investigate not only different bones, but also different areas of the same bone since not all sites of the skeleton外架)are similarly affecte
22、d by space conditions, " they added.Without gravity the body isn ' t bearing any weight so there is noaieednfor (钙)which makes bones strong, and it becomes empty into the bloodstream.The research team suggestedin future scientists should try to determine if the loss of bone density was only
23、 on weight-bearing bones on longer flights, also the possible recovery after returning to Earth.1. French scientists did their research on Russian astronauts, because.A. they only cared for the Russian astronautsB. they were not interested in their own astronautsC. the Russian government invited the

26、k D. slow参考答案(1 4 DBDA)Passage 4Water goes around and around Earth in a never ending journey called the water cycle (循环)。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 wat
27、er vapour cools off high in the sky and becomes 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 mixe
28、d in with the rocks and sand that lie in layers (层) below Earth ' s surface.Groundwater moves along slowly. How slowly? Maybe 1.5 kilometres in one century. Some of this water has been underground for thousands of years. And once groundwater is pumped out of the ground from a deep well (井)by peo
29、ple, it maytake hundreds of years for another water to take its place.1.1 n which order does water go around Earth?a .Fall down as rain or snow.b. Heated up by the sun on lakes, oceans and other wet places.c. Cool off high in the sky.d. Form clouds.e. Change into vapour.A. dacbe B. becda C. caebd D.

Groundwater travel in an unknown way.1-4 BCCBPassage 5Satellites are an important part of our ordinary lives.For example, the
32、 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 o
33、f our TV programs 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 kilometers above the equator.Sometimes we can see a satel
34、lite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11, 000 kilometers an hour exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae (天线)facingthe earth.Sometimes, it moves away from its orbit, So there ar
35、e 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 10-12 years.Satellites which are
36、 broken are sometimes repaired by astronauts or sometimes brought back to 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.1 .Which of
37、 the following is NOT done by satellites according 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. B.335,880 kilometers per ho
38、ur.C.11,000 kilometers per hour. D.110,000 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 televisi
39、on pictures.4 .What does the underlined 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-
40、12 years.B.Every time a satellite gets 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
41、 been caused by something biggera solar 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
42、been missing. Their absence, the longest 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 “solaminimum“ doesn't last long. Within a year, sunspots and solar stor
43、ms begin to build toward a new crescendo,the next 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 p
44、redicted that the next solar cycle could be the 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 s
45、ystems for the basics of daily life. Air travel 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 astronomers think that the solar cy
46、cle will go on but at low level. However, there is 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' absence B. the largest sunspot numberC. the malfunction of electronic de
47、vices D. the serious damage by sunspots2. What does 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 su
48、nspots has increased to a large extentC. the solar minimum 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
49、solar storms.C. It's difficult to predict sunspots.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 jour
50、ney started we have left so much trash(垃圾)there that scientists are now concerned that if we don't clean it up, we may all be in great danger.The first piece of space junk was created in 1964, when the American satellite Vanguard I stopped operating and lost its connection with the ground center
51、. However, since it kept orbiting around the Earth without any results, scientistsbecame 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
52、miles per hour. The junk varies from tiny pieces of 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 satelli
53、tes and damage traveling spaceship. Moreover, pieces 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 the
54、m from crashing into working satellites or space shuttles. 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 satel
55、lite.2. Why were scientists NOT concerned about space trash in the beginning?Bt was millions ofA. It no longer served any useful purpose. miles away from the Earth.ID. wasIt neverD. It may causeC. It did not cause any problems.regarded as similar to comets and stars.3. Which of the following stateme
56、nts is true about space junk?A. It is huge, heavy machines.changes position.C. It floats slowly around the Eblems for 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.
57、 Many nations have worked together to stop polluting 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-ye
58、ars away, the planet called Kepler-186f is about 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.said QuintaBut it is not exactly like Earth, NASA planetary scientist Elisa Quintana said. “ It mosre of an Earth csousin. It nsot an Earth tswin. It shares the same characteristics as Earth, but their parent stars are very different,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
