Mark and his brother Jason both were looking at the shining new computer enviously. Jason was determined not to go against their father’s wishes but Mark was more adventurous than his brother. He loved experimenting and his aim was to become a scientist like his father.
“Dad will be really mad if he finds out you’ve been playing with his new computer.” Jason said, “He told us not to touch it.”
“He won’t find out.” Mark said, “I’ll just have a quick look and shut it down.”
Mark had been scolded before for touching his father’s equipment. But his curiosity was difficult to control and this new computer really puzzled him.
“It was a strange-looking machine –one his dad had brought home from the laboratory where he worked. “It’s an experimental model,” his father had explained, “so don’t touch it under any circumstances.” But his warning only served to make Mark more curious. Without any further thought, Mark turned on the power switch. The computer burst into life and seconds later, the screen turned into colors, shifting and changing and then two big white words appeared in the center of the screen: “SPACE TRANSPORTER.”
“Yes!” Mark cried excitedly, “It’s a computer game. I knew it! Dad’s only been pretending to work. He’s really been playing games instead.” A new message appeared on the screen:
“ENTER NAMES
VOYAGER 1: …
VOYAGER 2: …”
Mark’s fingers flew across the keyboard as he typed in both of their names.
“INPUT ACCEPTED. START TRANSPORT PROGRAM. AUTO-RETRIEVE INITIATED(自动回收程序已启动).”
The screen turned even brighter and a noise suddenly rose in volume.
“I think we’d better shut it off, Mark,” Jason yelled, reaching for the power switch. He was really frightened.
But his hand never reached the switch. A single beam of dazzling white light burst out of the computer screen, wrapping the boys in its glow (光芒), until they themselves seemed to be glowing. Then it died down just as suddenly as it had burst into life. And the boys were no longer there. On the screen, the letters changed.
“TRANSPORT SUCCESSFUL. DESTINATION: MARS. RETRIEVE DATE: 2025.”
1.Why did Mark touch the computer against his father’s warning?
A.He wanted to take a voyage. |

As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治疗的) stem cells.
In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(细胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.
Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.
1.The best title of this passage probably is _______.
A.The importance of clone
B.First insects are cloned
C.The disagreement in clone
D.The advantages of clone
2.The scientists cloned flies because________.
A.there are fewer and fewer flies in the world
B.flies are easy to find and cheap to use
C.they can gain some experience before cloning other animals
D.it is safe to clone flies
3.The failure of most cloned animals is due to _______.
A.the difference of other animals’ genes
B.the improper technique of clone
C.the complex of other animals
D.the improper rearrange of the adult gene
4.It can be inferred from the last paragraph that ______.
A.the clone of insects before used grown-up cells
B.the clone of insects were never experimented before
C.this time scientists cloned flies successfully and easily
D.based on this success, other animals will be cloned in large quantities.

Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l There is a power siren(警报器) in the control unit. It makes a very loud noise.
2 Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That night I slept soundly because I was sure that no burglar(夜贼) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “There must be a burglar in the house,” Mary said. “What shall we do?”“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”I went downstairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, reset the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’m going downstairs to see what’s wrong.”I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animal) disappear behind the curtains.“Oh!” I said to myself. “That’s our burglar. ”When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well. I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.
1.The writer bought an alarm system to ________.
A.make sure that he got up early every day |
B.warn him when there were lizards in his house |
C.frighten burglars and tell him that somebody had got into the house |
D.make Mary feel safe to live in the large room |
2.The purpose of the three units was to________.
A.send a message to the control unit and start the siren |
B.sound their own sirens when the control unit told them so |
C.check that the control unit worked properly all the time |
D.give them enough light |
3.If the writer set the alarm and remained in the room for more than half a minute, _______.
A.nothing would happen |
B.the control unit would not work |
C.the siren would make a noise |
D.the dog would bark |
4.The purpose of the writer in writing the passage is to ________.

China has become Volvo's third largest market, with more of its car models to go on sale in the world's largest auto(汽车) market this year, Chief Executive Office (CEO) of Volvo Cars China said in Tianjin.
Alexander Klose, CEO of Volvo Cars China, told Xinhua at the Ninth Tianjin International Automobile Trade Show, being held from Friday to Wednesday.
Klose said Volvo Cars had entered a new time of fast development, adding that its sales volume in China roared in 2010.
Up to the end of September, Volvo's global sales volume was up 12.5 percent year on year(同年比), compared with 52 percent year-on-year rise in China, he said.
Two new Volvo sales centers opened in Beijing within merely one week in early October, about two months after east China's ZhejiangGeely Holding Group Co acquired(购得)the Swedish brand from the US auto giant Ford for $1.5 billion in early August.
Klose said he was confident of seeing tremendous(巨大的) growth in China's auto market in the next five years. "As the Chinese government has increased the tax rate for large displacement (排量)cars already, we now have a lot of cars below three liters(升), and I think we'll stick to that strategy, as you can see now the XC60 which was introduced today is just two liters," he said.
"As the technology advances, we'll probably even see 1.6 liter engines or 1.5 liter engines in the future," he added.
Volvo Cars is not the only automaker hoping to take advantage of China's rapidly growing auto market.
Bentley, the famous British luxury(豪华) carmaker, will open a new sales center in China at Tianjin Thursday, which is the 11th one in China, according to a press release(新闻发布) by Shanghai-based Zenith Integrated Communications Corp (Zenith) Saturday at the auto show.
Zenth is the public relations agent of Bentley in China. The automaker has sold 421 limousines(大型豪华轿车) to China in 2009, and the goal for 2010 is 777, the release said.
1.The word underlined in the third paragraph would probably be___.
A.shouted loudly | B.increased in large numbers |
C.reduced rapidly | D.burned brightly |
2.From this passage we can infer that ___.
A.The Ninth Tianjin International Automobile Trade Show was held from Friday to Wednesday. |
B.Volvo Cars is a world-famous carmaker in Britain. |
C.Of all the auto sales volume Volvo sales volume is only number one in China |
D.Volvo sales centers are developing very fast in China recently |
3.The text is mainly about____.
A.China Becomes Volvo's 3rd largest market |
B.Volvo Cars in China |

Will you be playing some music at work?
Music is particularly popular in the medical profession, especially among surgeons(外科医生). A recent survey shows that 90% of surgeons in the UK put music on the sound system in the theatre during operations. Plastic surgeons(整形外科医生)play the most music; it appears that ear, nose, and throat specialists the least.
But it isn’t only in surgeries(外科手术) where music is popular. In another recent survey, one-third of the 1,613 people said they listen to music while working. And 79% of them said that humming(哼歌)along improves their job satisfaction or productivity.
Is listening to music at work a good idea? Yes, say the experts. Many surgeons say that music helps to create a “calm atmosphere”, and a third of them added that it avoids getting bored! Also, listening to music raises the levels of a brain chemical that can help people focus. Office workers say it improves job satisfaction. Several studies suggest that it’s also good for hospital patients. Those listening to music through headphones during surgery require less anesthetic(麻醉剂), up to 50% less in some cases, and recover more quickly afterwards. “Sure, music reduces anxiety before surgery,” says Zeev Kain, an anesthetist at Yale University.
So, what type of music should we be listening to? Surgeons from the previous survey preferred rock, pop music and classical. And hip-hop is popular too. However, whatever the kind, it appears that self-selected music is the best choice. Pennsylvania State University research showed that when people chose their own music there was more stress reduction(下降). And other researchers found that when listening to self-selected music, surgeons did the maths faster and more accurately than when they were listening to music chosen for them.
1.The underlined word “theatre” in Paragraph 2 probably means ________.
A. an operating room
B. a rest room for surgeons
C. a waiting room in a hospital
D. a building where shows are performed
2.The surveys mentioned in the passage show ________.
A. music is popular in some professions
B. most surgeons in the UK are fond of singing
C. office workers learn a lot from listening to music
D. fewer than half of the people listen to music at work
3.What are the advantages of listening to music at work? ________.
①improving memory
②keeping people relaxed
③improving job satisfaction
④improving eyesight
A. ①④ B. ①② C. ②③ D. ②④
4.How should you choose music for work time according to the passage? ________.
A. Turn to the surgeons for help
B. Make your selection by yourself
C. Rock, pop music and classical are always good choices
D. The most popular music should be taken into consideration
5.The passage is mainly about ________.
A. how to choose music wisely

Americans Spend Their Free Time In Various Ways
America is a country of sports—of hunting,fishing and swimming,and of team sports like baseball and football.Millions of Americans watch their favorite sports on television.They also like to play in community orchestras(管弦乐队),make their own films or recordings,go camping,visit museums,attend lectures,travel,garden,read,and join in hundreds of other activities.The people also enjoy building things for their homes,sewing their own clothes,even making their own photographs.They do these things for fun as well as for economy.
But as much as Americans enjoy their free time,the country is at the same time a“self-improvement” country.More than 25 million adults continue their education,chiefly by going to school in the evening, during their own free time,at their own expense.Added to the time spent on personal activities,Americans a1so devote a great amount of their time to the varied needs of their communities.Many hospitals,schools,libraries,museums,parks,community centers,and organizations that assist the poor depend on the many hours citizens devote to these activities,often without any pay. Why do they do it?
There are several answers.The idea of cooperating and sharing responsibility with one another for the benefit of all is as old as the country itself.
When the country was first founded in 1776,it was necessary for the settlers to work together to live.They had crossed dangerous seas and risked all they had in their struggle for political and religious freedom.There remains among many Americans a distrust of central government.People still prefer to do things themselves within their communities,rather than give the government more control.
Sometimes people offer their time because they wish to accomplish something for which no money is paid,to do something that will be of benefit to the entire community.It is true that some people use their leisure because they are truly interested in the work;or they are learning from the experience.
No matter what the reason is,hundreds of thousands of so-called leisure hours are put into hard,unpaid work on one or another community need.
1.The writer mentions the foundation of the country in order to indicate ____.
A.the reason for Americans’ willingness to cooperate and share responsibility |
B.the American people’s determination to live |
C.the American people’s love for freedom |
D.the early history of America |
2.Which of the following best explains the meaning of the underlined word “leisure”?
A.work time B. spare time C. energy C. effort
3.This passage is mainly about ________ .
A.how Americans are devoted to their community activities |
B.why America is a “self-improvement” country |
C.why America is a country of sports |
D.how Americans spend their free time |

“Mama, when I grow up, I’m going to be one of those!” I said this after seeing the Capital Dancing Company perform when I was three. It was the first time that my dream took on a vivid form and acted as something important to start my training. As I grew older and was exposed to more, my interests in the world of dance certainly varied but that little girl’s dream of someday becoming a dancer in the company never left me. In the summer of 2005 when I was 18, I received the phone call which made that dream a reality: I became a member of the company dating back to 1925.
As I look back on that day now, it surely lacks any sense of reality. I believe I stayed in a state of pleasant disbelief until I was halfway through rehearsals (排练) on my first day. I never actually expect to get the job. After being offered the position, I was completely astonished. I remember shaking with excitement.
Though I was absolutely thrilled with the chance, it did not come without its fair share of challenge. Through the strict rehearsal period of dancing six days a week, I found it vital to pick up the material fast with every last bit of concentration. It is that extreme attention to detail (细节) and stress on practice that set us apart. To then follow those high-energy rehearsals with a busy show schedule of up to five performances a day, I discovered a new meaning of the words “hard work.” What I thought were my physical boundaries were pushed much further than I thought possible. I learned to make each performance better than the last.
Today, when I look at the unbelievable company that I have the great honor of being a part of, not only as a member, but as a dance captain, I see a tradition that has inspired not only generations of little girls but a splendid company that continues to develop and grow-and inspires people every day to follow their dreams.
1. How many years has the Capital Dancing Company existed when the author received the phone call from it?
A.180 | B.1925 | C.2005 | D.80 |
2.How did the author feel when she look back on that day now?
A.strange | B.unrealistic | C.indifferent | D.lucky |
3. Which of the following statement can best interpret the underlined sentence in paragraph 3?
A.Though I was excited, I should share the chance with others. |
B.Though I was excited, it’s fair to share the chance when there is challenge. |
C.Though I was excited, it’s a challenge for me to share the chance with others. |
D.Though I was excited, I know clearly where there is chance there is challenge. |
4.What conclusion could be drawn from the passage?
A.The company values practice most. |
B.The company extremely focus on intelligence. |
C.The company has an inherited tradition of inspiring its members break their limits. |
D.The company sets the members apart in order to extremely stress detail and practice. |

TIANJIN, Nov.23 (Xinhua)- Chinese scientists have signed a deal to establish a commercial animal cloning center in the northern port city of Tianjin, making the controversial science closer to mainstream acceptance.
The plant in the Tianjin Economic and Technological Development Area (TEDA), a government-sponsored business development park, will clone animals including sniffer and pet dogs, beef cattle and racehorses. Its main building is already under construction and due to be put to use in the near future, said a spokesman on Monday.
With an investment of 200 million yuan, the center will be jointly built by Sinica, Peking University’s Institute of Molecular Medicine, the Tianjin International Joint Academy of Biomedicine, and the Republic of Korea’s Sooam Biotech Research Foundation.
It will produce 100,000 cattle embryos a year initially, eventually increasing to 1 million, said Xu Xiaochun, board chairman of Boyalife Group, based in Wuxi. Chinese farmers are struggling to produce enough beef cattle to meet market demand, Xu said. The center, the largest ever worldwide, will also include a gene storage area and a museum, he added.
Scientists have cloned mice, cattle and other animals since the world’s first cloned sheep, Dolly, was born on July 5,1996 iii Britain. Since 2000, Chinese scientists have cloned sheep, cattle and pigs. China’s first commercial cloning company was established in September 2014 in Shandong with the birth of three pure-blooded Tibetan mastiff puppies.
Before this, cloning in China was limited to scientific research. More and more companies have shown interest in investing in the technology for commercial use, especially animal husbandry (饲养).

高二英语阅读理解极难题查看答案及解析
If I were writing a history of my family, some of the darkest moments recorded would be those surrounding Christmas trees. One would certainly think otherwise; selecting and putting up our trees have always been filled with risk. For example, one afternoon dangerously close to Christmas Eve my mother bought what she thought to be a bargain, a glorious tree that was so full and tall that we could hardly get it into the house. Once we did, my father immediately realized that we would have to hire a carpenter to build a stand for it. Another December, perhaps the very next one, we bought a tree earlier than we ever had before. We were happy with its shape and delighted that its size was manageable. We easily placed it in a stand, decorated it from top to bottom, and then self-satisfiedly sat back by the fire in its soft light. Two or three days passed and the truth could not be hidden; we had bought a tree cut so long ago that its needles were coming off. There was nothing to do but undecorate it, take it down, and begin tree shopping again. Our most recent Christmas tree offered still another difficult task. When we brought it home, once again it seemed larger than it was in the great outdoors. To complicate matters, we had bought a new stand, one whose nuts (螺帽) and bolts (闩子) worked more mysteriously than those of our old stands. I persuaded two young neighbors to stop playing basketball and to help us get the tree into the house and set it correctly in the stand. Unfortunately, no one noticed the mud on our helpers' shoes, so only after removing several reddish brown spots from the carpet were we able to discuss the question of where the lights and ornaments (装饰)were stored. Perhaps those who cut their own trees have tales more painful than these. I don't care to hear them, as my family's experiences are enough to cause me to make the following suggestion:" Let's forget the tree next Christmas. Let's simply hang some flowers on the front door and over the mirror in the hall. "
1.The darkest moments in the writer's family were with the fact that _____.
A.the family bought big Christmas trees |
B.they had problems decorating their Christmas trees |
C.they had problems picking suitable Christmas trees |
D.they had problems finding carpenters for putting up Christmas trees |
2.We can learn from the passage that the writer would like to _____.
A.forget about Christmas stories |
B.get the neighbors to put up their trees |
C.buy a better tree to celebrate Christmas |
D.make other decorations rather than Christmas trees |
3.When the writer said " my mother bought what she thought to be a bargain", he means ____.
A.she bought the tree at a cheap price |
B.she didn't really want to buy it |
C.she had to bargain hard with the salesman |
D.she couldn't afford a more expensive one |
4.Which of the following can be the best title for the passage?
A.How to Select a Christmas Tree |
B.No More Christmas Tree for Us |
C.Dark Moments of Life |
D.Christmas Without Trees |

In a room at Texas Children Cancer Center in Houston, eight-year-old Simran Jatar lay in bed with a drip (点滴) above her to fight her bone cancer. Over her bald (秃的) head, she wore a pink hat that matched her clothes. But the third grader’s cheery dressing didn’t mask her pain and weary eyes.
Then a visitor showed up. “Do you want to write a song?” asked Anita Kruse, 49, rolling a cart equipped with an electronic keyboard, a microphone and speakers. Simran stared. “Have you ever written a poem?” Anita Kruse continued. “Well, yes,” Simran said.
Within minutes, Simran was reading her poem into the microphone. “Some bird soaring through the sky,” she said softly. “Imagination in its head…” Anita Kruse added piano music, a few warbling (鸣, 唱) birds, and finally the girl’s voice. Thirty minutes later, she presented Simran with a CD of her first recorded song.
That was the beginning of Anita Kruse’s project, Purple Songs Can Fly, one that has helped more than 125 young patients write and record songs. As a composer and pianist who had performed at the hospital, Kruse said that the idea of how she could help “came in one flash”.
The effect on the kids has been great. One teenage girl, curling (蜷缩) in pain in her wheelchair, stood unaided to dance to a hip-hop song she had written. A 12-year-old boy with Hodgkin’s disease who rarely spoke surprised his doctors with a song he called I Can Make It.
“My time with the kids is heartbreaking because of the severity of their illnesses,” says Anita Kruse. “But they also make you happy, when the children are smiling, excited to share their CD with their families.”
Simran is now an active sixth grader and cancer-free. From time to time, she and her mother listen to her song, Always Remembering, and they always remember the “really sweet and nice and loving” lady who gave them a shining moment in the dark hour.
1.Simran Jatar lay in bed in hospital because ______.
A.most of her hair had fallen out |
B.she was receiving treatment for cancer |

2.What do we know about Anita Kruse’s project?
A.It helps young patients record songs. |
B.It is supported by singers and patients. |
C.It aims to replace the medical treatment. |
D.It offers patients chances to realize their dreams. |
3.What does the case of a 12-year-old boy suggest?
A.Most children are naturally fond of music. |
B.He was brave enough to put up performance. |
C.The project has positive effect on young patients. |
D.Singing is the best way to treat some illnesses. |
4.What is probably the best title for the passage?
