In a conference call with analysts，she announced better-than-expected quarterly results，even though profits were down. Ms. Fiorina also repeated why she believes her＄24 billion plan to acquire Compaq is the best way forward for HP，despite disapproval by Hewlett and Packard family members. Last week Walter Hewlett，whose father cofounded the company，expressed concern that the combination would increase HP's exposure（受到危害）to the decreasing PC market.There are two ways to defend the deal. One is to point out its advantages，which is what Ms. Fiorina did this week...“Having spent the last several months planning the combination of these two companies，we a re even more convinced of the power of this combination,”Ms. Fiorina concluded.It sounds too good to be true, and it almost certainly is. But the other way to defend the deal is to point out that，even if it was a bad idea to start with, abandoning could be even worse----a view that，unsurprisingly, Ms. Fiorina chose not to advance，but is being quietly put forward by the deal's supporters.Giving up the combination would be extremely painful for a number of reasons. Since the executive teams of both firms have committed themselves to the deal，they would be completely discredited（败坏名声）if it fell apart，and would probably have to go. Under the terms of the combination agreement，HP might have to pay Compaq as much as＄675m if it backed out. Thetwo firms would be considerably weakened；they would also be rivals (竞争对手) again，despite having shared technical and marketing information with each other over the past few months. In short，it would all be horribly messy. What can be done to save the deal? Part of the problem is that HP has no plan B. "They need a brand-recovery effort immediately,” says one industry analyst. HP must give the impression that it is strong and vital，rather than desperate，and that its future is not dependent on the deal going forward. That could make the combination look more attractive and bring investors back on board.41. What is Ms. Fiorina's attitude toward the combination of HP and Compaq?A.Forced permission.B. Strong disapproval.C. Enthusiastic support.D. Slighthesitation.42. Which of the following is not the good reason to promote the combination?A. The majority of the firm are in favor of the combination.B. No combination is even worse than combination.C. It can bring about a lot of advantages.D. There is no plan B to save the firm from trouble.43. What can we learn from paragraph 4?A. The executive teams of both firms can benefit a lot from the combination.B. The future of HP depends much on the combination.C. The two sides are eager to make this deal.D. Plan B can save HP out of trouble.44. What is the author's attitude toward the combination of HP?A. Negative.B. Supportive.C. Objective.D. Worried.BA lousy marriage might make you sick. Marital strife（婚姻不幸）and other bad personal relationships can raise your risk for heart disease, researchers reported Monday.What it likely boils down to（归结于）is stress----a well-known contributor to health problems, as well as a potential byproduct（副产品）of troubled relationships, the scientists said.In a study of 9，011 British civil servants，most of them married, those with the worst close relationships were 34 percent more likely to have heart attacks or other heart trouble during 12 years of follow-up than those with good relationships. That included partners, close relatives and friends.The study, in Monday's Archives of Internal Medicine，follows previous research that has linked health problems with being single and having few close relationships. In the new study, researchers focused more on the quality of marriage and other important relationships."What we add here is that being married is in general good, but be careful about the kind of person you have married. The quality of the relationship matters.” said lead author Roberto De Vogli, a researcher with University College in London.De Vogli said his research team is doing tests to see if study participants with bad relationships have any biological evidence of stress that could contribute to heart disease.Men and women with bad relationships faced equal risks, according to the study. Volunteers filled out questionnaires asking them to rate the person to whom they felt closest on several measures. These included questions about to what extent does that person "give you worries，problems and stress?"They also were asked about whether they felt they could confide in（向……透露秘密）that person，or whether talking with that person made them feel worse.Over the following 12 years，589 participants had heart attacks or other heart problems. Those with the highest negative scores on .the questionnaire had the highest risks，even taking into account other factors related to heart disease such as obesity（肥胖），high blood pressure and smoking.45. According to the text, stress isA. an unimportant contributor to health problemsB. an impossible factor to heart diseaseC. a potential byproduct of troubled relationshipsD. an obvious product of troubled relationships46. The underlined word “lousy" in the first paragraph could best be replace d byA. very cautiousB. very badC. very legalD. very selfish47. We know from the text thatA. people with the best close relationships were more likely to have heart attacksB. the previous research is mainly about the quali ty of marriage‘C. men and women with bad relationships faced different risks for heart diseaseD. the quality of the relationship is very important to people's health48. What is the passage mainly about?A. A study which links marital strife to heart disease.B. The difference between marital strife and heart disease.C. A study of 9, 011 British civil servants.D. A study which links a happy marriage with good personal relationships.CJapanese scientists have taken the first photographs of one of the most mysterious creatures in the deep ocean--the giant squid（鱿鱼）.Until now the only information about the behavior of the creatures which measure up to l8 meters (59 feet) in length has been based on dead or dying squid washed up on shore or captured in commercial fishing nets.But Tsunemi Kubodera, of the National Science Museum, and Kyoichi Mori of the Ogasawara Whale Watching Association, both in Tokyo have captured the first images of Architeuthis attacking bait 900 meters below the surface in the cold, dark waters of the North Pacific. "We show the first wild images of a giant squid in its natural environment,”they said in a report in the journal Proceedings B of the Royal Society.Little is known about the creatures because it has been so difficult to locate and study them alive. Large ships and specialist equipment, which are costly, are needed to study deep sea environments.The Japanese scientists found the squid by following sperm whales, the most effective hunters of giant squid, as they gathered to feed between September and December in the deep waters off the coast of the Ogasawara Islands in the North Pacific. They used a remote long-line camera and depth logging system to capture the giant squid in the ocean depths.The most dramatic character of giant squids is the pair of extremely long tentacles（触须），distinct from the eight shorter arms. The long tentacles make up to two-thirds of the length of the dead specimens（标本）to date. The giant squid appear to be a much more active meat-eating animals than researchers had thought.49. The passage mainly tells us that＿＿．A. Scientists captured a giant squid aliveB. Scientists captured a giant squid on cameraC. giant squids are special meat--eating animalsD. giant squids mainly live in the deep sea50. According to the passage，we can infer that the word "Architeuthis" should refer to＿．A. a scientistB. the sperm whaleC. a big shipD. the giant squid51. Which of the following about giant squids is TRUE?A. They like living in the cold and deep waters.B. They mainly feed on the dead fish.C. They like playing, using their tentacles.D. They have only eight arms around themouth.52. According to the passage, the scientists located the giant squid＿＿．A. through a remote long--line cameraB. by using depth logging systemC. by following sperm whalesD. by using the bait to attract themDBritish author J.K. Rowling at the release of her latest Harry Potter book called Harry Potter and the Deathly Hallows at the Natural History Museum in London, Friday July 20, 2007.J. K. Rowling has been seen at cafes in Scotland working on a detective novel, a British newspaper reported Saturday.The Sunday Times newspaper quoted Ian Rankin, a fellow author and neighbor of Rowling's, as saying the creator of the "Harry Potter" books is turning to crime fiction."My wife spotted her writing her Edinburgh criminal detective novel” the newspaper quoted Rankin as telling a reporter at an Edinburgh literary festival."It is great that she has not given up writing on Edinburgh cafes," said Rankin，who is known for his own police novels set in the historic Scottish city.Rowling began to write the Potter story in the Scottish city's cafes. Then, she was a struggling single mother who wrote in cafes to save on the heating bill at home.Now she's Britain's richest woman-worth＄1billion，according to Forbes magazine-and her sevenPotter books have sold more than 335 million copies worldwide.In an interview with The Associated Press last month, Rowling said she believed she was unlikely to repeat the success of the Potter series, but confirmed she had plans to work on new books.“I'll do exactly what I did with Harry---I'll write what I really want to write.” Rowling said.53. The main idea of the passage is that .A. J. K. Rowling has turned to other professions instead of writingB. Harry Potter and the Deathly Hallows has been releasedC. J. K. Rowling begins writing detective novelsD. J. K. Rowling's secret has been found out in Edinburgh cafes54. Why did J. K. Rowling write novels in cafes instead of at home at the very beginning?A. Because the cafes were comfortable and cheap.B. Because she liked drinking coffee while writing.C. Because the environment there contributed to her writing.D. Because she lacked money and couldn't afford the heating bills.55. Which of the following is NOT true according to the passage?A. J. K. Rowling's neighbor saw her writing police novels.B. Both Rowling's and Rankin's detective novels are set in Scotland.C. Rankin is also an author and is ;good at writing crime fiction.D. J. K. Rowling was a single mother and lived hard before.56. We can infer from the passage that J. K. Rowling＿．A. is unlikely to continue writing the Potter seriesB. wouldn't like to go to cafes to write her novelsC. will be the most famous and richest female worldwideD. is expert in writing detective novels which will be as popular as Harry PotterEHow did it make you feel when you learned that KFC's Beijing restaurants pulled three more items from their menu last week? There were fears that the items may have contained the cancer causing colouring Sudan I. Do you have any desire to take the food provider to court because it fed you something dangerous?After all，the law supposedly gives people the right to fight for their rights. But some experts have said it might not be so wise to go directly to court.Qiu Baochang, a lawyer in Beijing，suggested that consumers deal with the problem by consulting KFC. "In addition to the high costs, consumers' complaints are unlikely to win their case unless they can prove they have had the banned dye at KFC,” Qiu explained.One problem for those wanting to take action against the fast food chain is that few customers ask for or keep receipts. And, this is just the first step.If they can prove that their health has been damaged by KFC，they can sue（控告）the company. But that would be almost impossible to do so because the Sudan I damage is a long-term effect and is not immediately apparent.A KFC 'spokesperson said on Monday that the company was confident of being able to handle customers' complaints. "We will obey legal procedure if we receive any complaints.”57. Why did KFC's Beijing restaurants pull three more items from their menus?A.Because the company was afraid of not being able to handle customers' complaints.B. Because colouring Sudan I may have been contained in those items.C. Because the KFC's restaurants were accused of selling poisonous food to the customers.D. Because these items were no longer popular with the customers.58. The reason why the expert suggested 'not going directly into court’ is that＿．A. the costs will be highB. consumers can't prove the food contained Sudan IC. consumers can't prove the food at KFC damaged their healthD. all of the above59. This passage most probably appears in＿＿.A. a noticeB. a book on foodC. a story bookD. a newspaper60. What is the general idea of the passage?A. KFC's Beijing restaurants pulled three more items from their menus last week.B. How the consumers dealt with the KFC problem.C. How KFC handled the customers' complains.D. Consumers never forgot to ask for or keep receipts.第二节：补全对话：（5分）根据对话内容，从对话后的选项中选出能填人空白处的最佳选项。

My job was to 2l behind the runners in an ambulance 22 any of them needed medical attention. The driver and I were in an air-conditioned ambulance behind approximately one hundred athletes 23 to hear the sharp crack of the starting gun."We are supposed to stay behind the 24 runner，so take it slowly,” I said to the driver, Doug, as we began to creep forward."Let’s 25 hope all the runners are safe!” he laughed.As they began to pace themselves，the front runners started to 26 . It was then that my 27 were drawn to the woman in blue silk running shorts and a baggy white T-shirt."Doug, look！”We knew we were already watching our “last runner". Her feet were turned in，yet her left knee was turned out. Her legs were so crippled and 28 that it seemed impossible for her to be able to walk，let alone run a marathon.Doug and I watched in 29 as she slowly moved forwarD．We didn’t say a thing. We would move forward a little bit，then stop and wait for her to 30 some distance. Then we'd slowly move forward a little bit more.Finally，she was the 31 runner left in sight. Tears streamed down my face as I sat on the edge of my seat and watched with awe, amazement and even reverence（敬意）as she 32 forward with sheer determination through the last miles.When the 33 line came into sight, trash（垃圾）lay everywhere and the 34 crowdshad long gone home. 35 ，standing straight and ever so proud waited a man. He was 36 one end of a ribbon（带子）of crepe paper tied to a post. 37 slowly crossed through，leaving both ends of the paper fluttering behind her.I do not 38 this woman’s name，but that day she became a part of my life---a part I often depend on. For her，it wasn't about 39 the other runners or winning a trophy（奖品），it was about finishing what she had set out to do, no matter 40 . When I think things are too difficult or too time-consuming，I get those "I-just-can't-do-it"，I think of the last runner.

They said they knew she was OK when she cried for her teddy bear.Sunday's crash killed Kate Williams' pilot-grandfather, Allen D．Williams, 65, and another passenger, authorities said. The plane was found nose down and turned over in the icy water at the edge of a riverbank in the mountains of southeast British Columbia."What saved her life was being strapped into that car seat," said Mike Plonka, a member of the search-and-rescue team. "You could see that she was very frightened. Her big concern at the time was her little teddy bear. She didn't want to leave without it...” "She was just pointing at it and calling it ‘Baby’.”he said Monday. The girl suffered head injuries but was reported as stable,hospital officials in Golden said. She was reunited with her parents.Police said the Cessna 172 was on its way to Edmonton when it took off from Golden around 1 pm Sunday into low clouds and snow. Visibility（能见度）was poor. An hour later, the Search and Rescue Centre in Victoria picked up the plane's emergency signal from somewhere near the Blaeberry River.A team using a hand-held beacon locator（定位器）found the wreckage, and two military search and rescue technicians--Sgt. Scott Elliston and Master Cpl. Bruno Lapointe---landed nearby in a helicopter. As they checked for survivors, they discovered the girl alive but surrounded by debris（残骸）in the back of the plane. The two soldiers tried to remove her from the wreckage, but she made it clear she didn't want to leave without her teddy bear."I got her out and I handed her to Bruno. She was calling out for her teddy bear. I picked up the teddy bear to give it to her but it was covered with snow. She wasn't too happy that it was covered with snow so I brushed it off.＂Elliston said.Williams was CEO and founder of Edmonton-based A．D．Williams Engineering Inc.

The successful applicant bid（喊价）7,500 dollars last week to become Holt.Holt, a philosophy student from the southern coastal city of Wollongong who has set up a website to explain his actions and ask for donations to charity, said he was unable to explain why he sold his life.In his sales place Holt said the winner would have a four-week training course in how to be him---including lessons on how to surf, climb, skateboard, fire twirl and do handstands--as well as two months of on-call support afterward. He also promised to introduce the winner to all his friends and potential lovers, including eight girls he had been flirting（调情）with."Lifestyle is very social. It includes a lot of going out,” he noted on his eBay advertisement. "Friends will treat you exactly as they have treated me. This includes friends who take me surfing,running, climbing and cook for me. All of these features will be transferred over to the winning applicant.”His legal identity, passport, qualifications and future inheritance（继承权）were not for sale. 45．The passage is mainly about .A．how to sell goods on the auction website eBayB．how to make friends through the InternetC．an Australian who sold his own life on the internetD．the reason why an Australian sold his possessions46．The Australian young man sold all of the following possessions EXCEPT A．name, a laptop and a pushbikeB．phone number, CDs and a surf boardC．clothes, friends and a nice lampD．passport, qualifications and an ex-girlfriend47．From the passage we know that .A．Holt set up a website to explain why he sold his lifeB．Holt had been keeping love relationship with several girlsC．The auction winner bid for Holt at the price of 7,500 US dollarsD．The seller made a lot of advertisements to sell his possessions48．It can be inferred from the passage that .A．Nicael Holt is a young man who is fond of sportsB．Nicael Holt sold his possessions for lack of moneyC．Nicael Holt sold his life in order to make moneyD．Nicael Hoh refused to give the winner two months of on-call supportCNov, 5, 2005—More and more TV shows, movies and sporting events are being broadcast in High Definition (HD) —including “Good Morning America.” If you want to join the millions who are already experiencing a superior picture, you’ll need a High Definition TV (HDTV). But even if you’re ready to retire your old TV —or move it into the back bedroom where no one will ever see it —you’re bound to have lots of questions before you make an investment in a new drool-worthy HDTV.You might be wondering about hardware, cost and how to actually receive High Definition p rogramming on your set. “GMA” technology contributor Becky Worley offers this primer (入门书) to understanding the complicated world of HD.What is HDTV ①？High definition TV is a richer transmission of television signals that makes for a more vivid viewing experience. HDTV is to standard TV what FM radio is to AM radio. HDTV is crisp , clear and noise-free, with resolution that is at least twice that of analog (模拟信号)television and CD-quality sound .How Do I Get HDTV ②?HDTV signals are broadcast via antennas in urban areas, and via satellite TV or cable TV.To receive an over-the air HDTV signal, you must live within a certain radius（半径）of an HDTV broadcast antenna and have the proper HDTV tuner (调谐器) / antenna (天线) installed inyour home .To receive a Cable or Satellite HDTV signal, you must have a proprietary HDTV set-top box supplied by your provider.Not all programming is available in HDTV yet, but many network shows and sporting events are currently in HD and many more are converting over.When you watch a DVD on your HDTV, it is not technically HDTV quality, but it will look crisper on your HDTV than on a regular TV.HDTV, HD-Ready TV, and EDTVThere are three major terms that will describe the high-end TV sets that are on sale today :HDTV ③are TV sets that can receive and process over-the-air HD signals. You may need an antenna to receive the HD signal, but an HD tuner is built into the set and can process the signal without any other equipment. If you want to receive an HD signal from your cable or satellite provider, you will need one of the provider’s proprietary set-top boxes.HD-Ready TV are TV sets that need an additional piece of hardware to actually receive the HD signal, such as a stand-alone HD tuner (from $250 and up) or the set-top HDTV box provided by your cable or satellite TV company.EDTV stands for Enhanced Digital Television. The visual quality of an EDTV is better than a standard analog TV, but is not as crisp or bright as a true HDTV.49．Which of the following best describe the features of HDTV?A．It offers more TV channels and choices of programs.B．It offers more interesting and entertaining programs.C．It offers programs with clearer pictures and sound of better quality.D．It offers program for high technology50．How to understand the underlined sentence “HDTV is to standard TV what FM radio is to AM radio.” in this passage? It is .A．an example to show HDTV is different from common TV.B．a comparison to show HDTV is more advanced than common TV.C．an example to show the similarity between HDTV and FM radio .D．a comparison to show HDTV is better than FM radio .51．Does “HDTV” carry the same meaning in different places (①②③) of this article ?A．①and ②carry the same meaning while ③carries different meaning .B．①and ③carry the same meaning while ②carries different meaning .C．②and ③carry the same meaning while ①carries different meaning .D．①, ②and ③all carry the same meaning .52．If you want to receive HDTV program at home, you should have .A．an antenna , an HDTV set and a tunerB．an HD-ready TV set and live within the radius of an HDTV broadcast antennaC．an HDTV set , an antenna and live within the radius of an HDTV broadcast antennaD．an EDTV set and a set-top boxDAn Earthship is a home that is built of materials such as old tires and aluminum cans. It is the idea of a man named Michael Reynolds. Many Earthships are more or less self-sufficient because they provide their own heat, air and water. They often have gardens watered and fed by wastewater. They are comfortable and ecologically friendly.The main materials used in building Earthship is tires. Tires are plentiful and can’t be recycled like paper, plastic and metal. While building supplies for most houses can be very expensive, old used tires are free. First, the tires are packed tightly with dirt. Each full tire weighs as much as 400 pounds. The tires are then loaded like bricks. The walls are extremely strong. They also help keep a leveled temperature in the house (between 60 and 70 degrees) without heating and cooling systems.The walls inside the Earthship are made of aluminum cans that are held together by cement. Then they are coated with adobe (专坯) or stucco (灰墁).The roofs of Earthship are sloped so that rain and snow run into large tanks. These tanks hold all the water for the house, and pumps push the water through the pipes. Sometimes, water flows in certain areas of the house as waterfalls! Water that has been used is pumped out into the gardens where owners grow much of their own food.In most of these houses, the southern side has huge windows that take in winter sunlight as a source of heat. Summer sun does not come in through the south windows, so it doesn’t get too hot in the summer. The house also has solar panels(太阳板) that gather energy for lights and hot water and cooking. The Earthship have all the comforts of a regular house without the high cost of electric bills!In a time when we are running out of energy resources, pollution is bad, and waste is piling up, Earthships are the best places to live in. For people who truly care about the environment, Earthship provide a great alternative to traditional houses. You won’t be giving up any comforts, and the styles are attractive. We all hope that more and more people will build Earthships and take a huge step toward helping the environment and saving our planet.53．What is the main idea of the passage?A．Earthships are a good way to live and protect the environment.B．Tanks hold water collected from rain and snow.C．It’s important to grow your own food in a vegetable garden.D．People who live in Earthships usually live in the desert.54．What does the underlined word “They” in Paragraph 2 refer to?A．Earthships B．Tires C．Bricks D．Walls55．Which of the following sentences states an opinion rather than a fact?A．Earthships are made out of tires and cansB．Tanks collect water for use in EarthshipsC．Earthships can help save our planetD．Tires can’t be recycled but bottles and paper can56．Which evidence best supports the idea that Earthships are environmentally friendly?A．They were invented by Michael Reynolds.B．Water that has been used is pumped out into the garden.C．Summer sun does not come in through the south windows.D．This kind of house is becoming a reality.57．Which statement is an example of propaganda（宣传）？A．The house also has solar panels that gather energy for lights and hot water.B．Earthships provide a great advantage over traditional houses.C．The walls are then coated with adobe or stucco.D．The construction of houses made of recycled materials has been growing.EIt was a cold night in September. The rain was drumming on the car roof as George and Marie Winston drove through the empty country roads towards the house of their friends, the Harrisons, where they were going to attend a party to celebrate the engagement of the Harrisons' daughter, Lisa. As they drove, they listened to the local radio station, which was playing classical music.Suddenly the music on the radio was interrupted by a news announcement: "The Cheshire police have issued a serious warning after a man escaped from Colford Mental Hospital earlier this evening. The man, John Downey, is a murderer who killed six people before he was captured two years ago. He is described as large, very strong and extremely dangerous. People in the Cheshire' area are warned to keep their doors and windows locked, and to call the police immediately if they see anyone a cting strangely.”Marie shivered. "A crazy killer. And he's out there somewhere. That's scary.”"Don't worry about it,”said her husband. "We're nearly there now. But this car is losing power for some reason.”As he spoke, the car began to slow down. Finally they rolled to a halt, as the engine died completely. Just as they stopped, George pulled the car off the road, and it came to rest under a large tree,"Blast!”said George angrily. "Now we'll have to walk in the rain.”"But that'll take us an hour at l east,” said Marie, "And I have my high-heeled shoes and my nice clothes on. They'll be ruined!”"Well, you'll have to wait while I run to the nearest house and call the Harrisons. Someone can come out and pick us up," said George."But George! Have you forgotten what the radio said?""You'll have to hide in the back of the car. Lock all the doors and lie on the floor in the back, under this blanket. No one will see you. When I come back, I'll knock three times on the door. Then you can get up and open it. Don't open it unless you hear three knocks," George opened the door and, slipped out into the rain. He quickly disappeared into the blackness.Marie quickly locked the door and settled down under the blanket in the back for a long wait.Suddenly she heard three slow knocks, one after the other, also on the roof of the car. Was it her husband? Should she open the door? Then she heard another knock, and another. This was not her husband. It was somebody or something else. She was shaking with fear, but she forced herself to lie still. The knocking continued----bump, bump, bump, bump.Many hours later, as the sun rose, she was still lying there. The knocking had never stopped all night long. She did not know what to do. Where was George? Why had he not come for her?Suddenly, she heard the sound of three or four vehicles, racing quickly down the road. Someone had come! Marie sat up quickly and looked out of the window.The three vehicles were all police cars. Several policemen leapt out. One of them rushed towards the car as Marie opened the door. He took her by the hand."Get out of the car and walk with me to the police vehicle. Miss! You're safe now. Look straight ahead. Keep looking at the police car. Don't look back. Just don't look back.”Something in the way he spoke filled Marie with cold horror. She could not help herself. About ten yards from the police car, she stopped, turned and looked back at the empty vehicle.George was hanging from the tree above the car, a rope tied around his neck. As the windblew his body back and forth, his feet were bumping gently on the roof of the car-bump, bump, bump, bump.58．What was the reason for the news announcement on the radio?A．Some people had been seen acting strangely in the Cheshire area.B．The police were warning of accidents on the roads in the bad weather.C．Six people, including John Downey, had been murdered.D．A dangerous prisoner had escaped.59．Why did Marie stay in the car when George left?A．She was afraid to go out in the dark.B．So no-one would steal the car.C．Her clothes weren't suitable for the rain.D．She wanted to get some sleep.60．Why did the policeman tell her not to look back when he brought her out of the car?A．The killer was waiting behind her.B．He wanted her to forget everything that had happened during the night.C．He didn't want her to see the damage done to the car.D．He didn't want her to see the body of her husband.第二节：根据对话内容，从对话后的选项中选出能填人空白处的最佳选项。
