(时间:90分钟 满分:110分)
第一部分 阅读理解(共两节;满分30分)
第一节 (共10小题;每小题2分,满分20分)
阅读下列短文,从每题所给的四个选项(A、B、C和D)中,选出最佳选项。
A
What science fiction (story) once told about other worlds far away is now a fact. Astronomers (experts at the science of the universe) prove another solar(of the sun)system like ours with some planets in the constellation Andromeda(仙女座).
Geoffrey Marcy is a professor of astronomy and physics at San Francisco State University and says, “What we have found now,for the first time ever, is indeed a fully-grown system-of planets around the star Upsilon Andromeda. It appears to have three planets,one close in,one at a middle distance,and one farther out. The star is slightly larger than our sun. The planets are huge,like our Jupiter(木星).”
Marcy's partner in this research,Debra Fischer, describes the solar system,“Here are the inner planet that goes around every 46 days, the middle planet that goes around every 242 days, and then the outer planet that goes around every three and a half to four years.”
Astronomically, it's not far away, 44 light years. The sun of that solar system,Upsilon Andromeda,is so near and bright that it can be seen by using no equipment during summer and fall.
For twelve years astronomers searched the skies in the belief that if our sun has planets around it, surely others do, too. Geoffrey Marcy says, “And then starting three and a half years ago, we began finding for the first time planets singly, one planet here around one star...”
“When I look up at the stars now at night, I can imagine easily that every one of them has planets around them,” says Debra Fischer.
It was a tremble (shaking)in the star that led Marcy to the planets. “The star rocks around due to the gravity of the planet as a dog owner gets pulled around by a little dog.”
Can they support life We don't know, because present technology is not advanced enough to determine what the planets are made of. That, Marcy says,is astronomy's next challenge.
1.What's the relation between Andromeda (A), Upsilon Andromeda system(U)and the mentioned three planets(P)
A
B
C
D
答案与解析:B 推理判断题。通读全文可知Andromeda是一个星座,像太阳系;Upsilon Andromeda是一颗恒星,像太阳;three planets是它的三个卫星,因此可推出B项正确。
2.According to Debra Fischer,in the new solar system, ________.
A.the farther a planet is from the star, the longer it takes to go around the star
B.the larger a planet is,the shorter it takes to go around the star
C.it takes all the planets around three and a half to four years to go around the star
D.the planets move around the star at the same(均匀) speed
答案与解析:A 推理判断题。根据天文常识及本文所述,任何行星的卫星的运转周期不可能是一致的,越是远离行星,一般运转周期越长。
3.What led to Marcy's discovery of the planets
A.That he found a dog owner was pulled by his dog.
B.The tremble of Upsilon Andromeda.
C.That any planet has gravity.
D.That he believes any star has its planets.
答案与解析:B 细节理解题。由倒数第二段可知。
4.We can infer that the scientists are ________.
A.to find out whether the planets can support life
B.to find means to communicate with the living beings on the planets
C.to find means to travel to the planets
D.soon to be able to answer the question of whether there is life on these planets
答案与解析:A 推理判断题。其他几项提到的不是本文重点或没提及。
B
The earth is the only planet that scientists think has life. Why does the earth have life while the other planets (行星) don't For one thing, the earth is just the right temperature. As the_third_planet from the sun, the earth seems to be just the right distance away. The planets which are closer to the sun are hot that their surfaces bake (烘烤) in the sun. The farthest planets are cold balls.
When the earth developed — which scientists believe may have happened about 4 billion years ago — many gases covered the earth. The gases caused the earth to be hot. But something wonderful happened. The temperature was just right for thick clouds to form. It rained very hard for a very long time. This gave the earth its oceans. Water made it possible for plants to grow. The plants created oxygen in the atmosphere. Oxygen is the gas that humans and animals breathe.
Only one other planet in the solar system seems to be something like the earth. That planet is Mars (火星). Mars is smaller than the earth, and it is quite a bit cooler. But it is not too cold for humans. On some days, the temperatures are as low as a winter day in the northern United States. If you wore a special space suit, you could walk around on Mars. You would have to bring your own air to breathe, the air on Mars is too thin to breathe.
Mars has the largest volcano (火山) in the solar system. It is sixteen miles high. The highest volcano on the earth is five miles high. The most unexpected (未预测到的) sight on Mars is dried up river beds. Scientists believe that Mars was once much better than it is now. Does this mean there could have been living things on Mars Scientists are not sure, but there has been no sign so far.
5.Which of the following is NOT the reason that the earth has life
A. The earth is just the right temperature.
B. The volcanos on earth are lower than those on Mars.
C. There is oxygen in the atmosphere of the earth.
D. The earth seems to be just the right distance away from the sun.
答案与解析:B 细节理解题。文中提到地球是可证实的唯一有生命存在的太阳系行星,其原因包括地球合适的温度、距太阳距离适中和大气里含有氧气等。B项火山与此无关。
6.The underlined phrase “the third planet” in the first paragraph refers to ________.
A. the Sun B. the Moon
C. the Earth D. the Mars
答案与解析:C 词义猜测题。根据第一段中内容可知距离太阳第三远的行星指的是地球。
7.Which of the following about the Mars is NOT true
A. There could have been living things on Mars.
B. Mars has the largest volcano in the solar system.
C. There is almost no oxygen in the air on Mars.
D. Mars is smaller than the earth, and it is quite a bit cooler.
答案与解析:A 细节理解题。文章最后一段提到火星上有干涸的河床的迹象,但这一点并不能证实火星上存在生命,因为还没有生命迹象,故A项不正确。其他三项都与文章相符。
C
Many of us are fascinated by time travel. Who wouldn't be enthralled by returning to the past or seeing the future But time travel seems to be possible only in our imagination — or in most cases, in science fiction.
Science fiction is a world where impossible things can become possible. But science fiction is not entirely fiction since it is based on science theories and principles. I have compiled some of the popular ways by which time travel is made possible in fiction books:
●Through the wormhole(虫孔)— It is a shortcut between points in space-time. According to Einstein, an object can pass through this if it can travel at the speed of light with infinite mass. An example of a wormhole is described in Riddle of the Red Bible.
●Through a black hole — A black hole is a vacuum in space where light cannot even escape or pass through. In some sci-fi movies, like Star Trek, black holes become the means to travel through time.
●Through time machines — In fiction, time machines are complex vehicles that can travel faster than light. A time machine can be a strange vehicle like TARDIS in Doctor Who or a specially modified car like the one used in Back to the Future.
●Through a parallel(平行的) universe — Another popular way to travel through time is to be able to slip or slide into a parallel universe where one can go back to a point in time and see a different reality.
Though we know time travel may not be possible, it is still an entertaining subject and a heated topic for most of us.
语篇解读 本文作者在文中介绍了科幻小说里讲述时间旅行的几种方式。
8.The underlined word “enthralled” in the first paragraph can be replaced by “________”.
A.thrilled B.confused
C.shocked D.upset
答案与解析:A 词义猜测题。从第一段中的“Many of us are fascinated by time travel”和“returning to the past or seeing the future”可推知,画线词意为“被迷住的,着迷的”,与A项意思最为接近。
9.The means of travelling through a black hole is described in ________.
A.Doctor Who
B.Back to the Future
C.Star Trek
D.Riddle of the Red Bible
答案与解析:C 细节理解题。从第四段中的“like Star Trek,black holes become the means to travel through time”可知选C。
10.Which of the following statements can be inferred from the passage
A.Time travel will never become possible even in the far future.
B.Time travel through a time machine will be the most common means.
C.Sci-fi writers have some similar experience as they describe in their fiction.
D.Many ways of time travel are described in science fiction besides the mentioned fours.
答案与解析:D 推理判断题。从第二段最后一句中的“some of the popular ways by which time travel is made possible in fiction books”这一信息可知,除了作者在文章中列举的这些方式之外,科幻小说里还介绍了其他方式。所以选D。

Dear_Mr._Smith,
I_am_writing_to_request_the_valuable_chance_to_be_one_of_the_homestay_families_for_the_American_students. As an active girl in senior one, Guangming School, I'm quite good at English. My parents, who are kind and friendly, are for my idea that I host an American student. We have a clean and comfortable house, which lies in a beautiful area of the city. Luckily, we have extra rooms for guests. My mother cooks well so the student will be able to enjoy delicious Chinese food. What's more, my father is an excellent driver and we will show the foreign student around some local places of interest in our area. I'd greatly appreciate it if I could have the chance to make friends with her/him.
I'm looking forward to your reply.
Yours_sincerely,
Li_Hua
