A new study suggests that the more teenagers watch television , the more likely they are to develop depression (抑郁)as young adults. But the extent to which TV may or may not be to blame is a question that the study leaves unanswered.
The researchers used a national long-term survey of adolescent health to investigate the relationship between media use and depression . They based their findings on more than four thousand adolescents who were not depressed when the survey began in 1995.
As part of the survey, the young people were asked how many hours of television or videos they watched daily. They were also asked how often they played computer games and listened to the radio.
Media use totaled an average of five and one-half hours a day. More than two hours of that was spent watching TV.
Seven years later, in 2002, more than seven percent of the young people had signs of depression. Their average age at that time was twenty-one.
Brian Primack at the Universtiy of Pittsburgh Medical School was the leading author of the new study . He said every extra hour of television meant an eight percent increase in the chances of developing signs of depression.
The researchers say they did not find any such relationship with the use of other media such as movies, video games or radio. But the study did find that young men were more likely than young women to develop depression given the same amount of media use.
Doctor Primack says the study did not explore if watching TV causes depression . But one possibility, like sports and socializing . It might also interfere with sleep, he says, and that could have an influence.
The study was just published in the Archives of General Psychiatry. In December, the journal Social Indicators Research published a study of activities that help lead to happy lives. Sociologists from the University of Maryland found that people who describe themselves as happy spend less time watching television than unhappy people. The study found that happy people are more likely to be socially active, to read, to attend religious services and to vote.
60．The average age of the depressed young people should be       when they began to receive the survey.
A．21     B．15     C．14     D．20
61．According to the passage, which of the following can possibly lead to depression?
A．Swimming                     B．Attending a party
C．Attending religious services       D．Watching TV for a long time.
62．We can learn from the passage      .
A．the survey lasted a short time
B．over 280 teenagers who received the survey became more or less depressed in 2002
C．men are more likely to become depressed than women
D．the study about the relationship between media use and depression was published in the journal Social Indicators Research
63．What is the best title for the passage?

China has now mapped out plans for its next four launches in the Shenzhou program on the next flight. But one conclusion seems to have escaped most reports in the aerospace media. The flight of Shenzhou 7 could be timed to coincide with the Beijing Olympics. Plans for the 2008 Summer Olympics call for the events to be held between the 8th and 24th of August. It's reasonable to expect that China will use the event to promote its achievements before the world, and human spaceflight is China's most significant recent breakthrough.
Shenzhou 7, China's next manned space mission, was originally advertised for 2007. This fit into the pattern of staging a two-year gap between crewed Shenzhou missions, which have previously launched in 2003 and 2005. But Chinese media statements have recently amended this to 2008. Chinese media have reported that while the overall program is going well, more time is needed to work on the spacesuit that will be used on this flight to stage China's first spacewalk. It's possible that Chinese engineers want to make best preparations for this complex mission.
China could intend to carry out the mission of Shenzhou 7 just as media attention is focused on the lead-up to the Olympics. The crew of the flight, and possibly China's other flown astronauts, could then take part in the opening ceremony. China has previously feted her space travellers in great celebrations, such as the Hong Kong event that saw Yang Liwei singing with actor Jacky Chan.
China has also suggested that the activity will be carried out by a single astronaut, and has indicated that half an hour is a rough estimate of the planned time for the spacewalk. China is apparently following suit, probably for the same reasons of conservative mission planning and safety.
41. From the first paragraph we can infer that ________.
A. China hasn’t made its plan for the Beijing Olympics
B. The new Shenzhou program are known to all the reporters
C. China has planned to send up Shenzhou 7 in 2008
D. Beijing Olympics will be held during the flight of Shenzhou 7
42. China has decided to carry out its human spaceflight in 2008 in order to ______.
A. make the Beijing Olympics more interesting
B. show its great achievements to the world
C. prove that China is a developed country
D. introduce its science and technology to the world
43. Which one of the following is WRONG according to this passage?
A. China sent its first manned spacecraft in October of 2003.
B. Chinese engineers want to make more preparations for Shenzhou 7.
C. The spacesuit for the flight of Shenzhou 7 hasn’t been prepared well.
D. Two Chinese astronauts walked in space in 2003.
44. The underlined word “amended” in the passage has a similar meaning to ______.
A. improve            B. change                     C. expect               D. decide
45. What would be the best title for this passage?
A. The Beijing Olympics.                        B. The Shenzhou Olympics.
C. China’s Shenzhou Program.                 D. Spacewalk in 2008.

Heavy snow blanketed Anhui and Hubei provinces yesterday, cutting off power to some villages and blocking roads. Meanwhile, more snow is expected to cover the south in the coming three days.
Meteorologists said that the snow, which started Sunday night, is expected to fall throughout the south until this Friday, with temperatures falling below zero. The precipitation is expected to help relieve the severe drought conditions.
The temperature in the north will rise after this Friday and the south will be warmer after Nov 22nd, forecasters predicted yesterday.
The national meteorological watchdog issued an orange alert-the second—highest level-for snowstorms yesterday morning, warning that snowfalls in some areas will reach 20 mm at most.
Snowstorms refer to snowfalls that reach 10 mm in 24 hours. Snowfalls below 10 mm and above 5 mm are called heavy snows.
Last Friday, officials from the Hubei provincial government asked the transportation department, the meteorological bureau and related departments be fully prepared for the coming snow, with an emergency team ready to provide around-the-clock assistance.
The predicted snow in the south did not bring much trouble to air and rail travel with advance preparation.
The provincial education bureau declared an emergency plan on Sunday, asking primary and high schools to close when the snowstorms become severe.
The 16 expressways in snow-hit places in Hubei were scattered with 42.8 tons of snow-melting agents and about 4.580 sqm of anti-slip fabric. The latest information from the provincial expressway administration yesterday showed that traffic flowed smoothly during the snow.
The Tianhe Airport in Wuhan, Hubei province, had seven snow-melting vehicles working to ensure timely take-offs and landings.
The Anhui meteorological bureau declared all emergency alert because of the snowstorm on Sunday, with 43 cities and counties issuing alerts for snows and two issuing alerts for frozen roads. Shucheng county and Huoshan county issued time top alert because of the snowstorms on Sunday.
Luogang airport in Hefei, Anhui Province, was shut down for four hours since 7 a.m. yesterday due to the heavy snow, Xinhua reported.
The snow caused time rush-hour traffic to be heavily congested and many commuters left home earlier than usual in the morning.
Ye Wei, a worker at Hefei University of Technology, said his ride to work took a half-hour more than usual.
“Maybe tomorrow I will have to get up one hour earlier than before, because of the frozen roads,” Ye said.
The heavy snow first hit northern China, claiming dozens of lives, causing hundreds of injuries, paralyzing the traffic and grounding hundreds of flights.
The whiteout that began Nov 9th has killed at least 32 people and affected more than 9.6 million in seven provinces. More than 15,000 buildings have collapsed and nearly 300, 000 hectares of farmland have been destroyed, Ministry of Civil Affairs officials said on Sunday.
The snowfall was the heaviest in the past six decades in some northern and central provinces like Hebei, Shanxi, Shaanxi and Henan, with an economic loss reaching 7 billion yuan（$ 1.02 billion）, ministry officials said.
67．Which of the following call be the best title for this passage?
A．Heavy Snow Coming to Southern China.
B．Heavy Snow Blanketed Anhui and Hubei.
C．Snowy All Over China.
D．China in the Future Will Be Cold.

Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
“ I think we are knocking at the door of immortality (永生),” said Michael Zey, a Montclair State University business professor and author of two books on the future. “ I think by 2075 we will see it and that’s a conservative estimate.”
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology(納米技術(shù)) make it likely that humans will live in the future beyond what has been possible in the past. “ There is a great push so that people can live from 120 to 180 years,” he said. “ Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years.”
However, many scientists who specialize in aging are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. “ It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?” said Leonard Poon, director of the University of Georgia Gerontology Center. “ At present people who could get to that point are not in good health at all.”
小題1:By saying “ we are knocking at the door immortality”, Michael Zey means_____.
A．they believe that there is no limit of living
B．they are sure to find the truth about long living
C．they have got some ideas about living forever
D．they are able to make people live past the present life span
小題2:Donald Louria’s attitude toward long living is that_____.
A．people can live from 120 to 180
B．it is still doubtful how long humans can live
C．the human body is designed to last about 120 years
D．it is possible for humans to live longer in the future
小題3:70. The underlined “ it” (Para. 4) refers to_____.
A．a(chǎn) great push
B．the idea of living beyond the present life span
C．the idea of living from 200 to 300
D．the conservative estimate
小題4:What would be the best title for this text?
A．Living longer or not
B．Science, technology and long living
C．No limit for human life
D．Healthy lifestyle and long living.

In 2007, the first solar electric boat crossed the Atlantic Ocean. Now a Swiss group wants to cover that distance and keep going, circling the globe on nothing but the sun’s power for the first time.
The team of engineers and scientists has started the building of its 98-foot long boat, named Planet Solar, in Kiel Germany. The boat’s power will come from the 5,000 square feet of solar panels（電池板）, about the size of two tennis courts, covering its broad deck. When the sun is shining bright above, they will turn 23 percent of the sun’s rays to energy — six percent more than average solar panels.
Even though batteries aboard Planet Solar can store enough energy to power it through up to three days of cloudy weather, the sailors will try to avoid clouds: constant communication with the French meteorological institute, Meteo France, will help the sailors stay with the sunny course.
The $11.5 million project, which is led by Raphael Domjan, should be ready for its first voyage next summer. The solar electric boat will warm up in European waters, and attempt to deal with traveling around the globe in spring 2011. At a maximum speed of 16 mph, Planet Solar will be the fastest solar electric boat. The team expects to finish the first leg of its journey across the Atlantic in about two weeks, compared to the six months the solar boat took back in 2007.
If sailing by sun becomes practical, it would be a return to the green boating methods of the days of Christopher Columbus. Those long-ago voyages relied only on a different type of renewable energy: wind. And, if wind-powered sails could be combined with solar panels, we might really pick up the boating speed.
57. Which of the following is NOT true about Planet Solar?
A. Its deck is covered by solar panels.
B. It will be the fastest solar electric boat.
C. It is 98-foot long and is to be made in Germany.
D. It can turn 17 percent of the sun’s rays into energy.
58. Planet Solar will be likely to __________ in continuous rainy weather.
A. continue traveling forward
B. ask the local weather station for help
C. stop to wait for the weather to clear up
D. turn to Meteo France for help to choose the sunny course
59. What can be inferred from the passage?
A. Sailing by solar energy has not been widely used in today’s green boating.
B. Planet Solar will be the first boat to circle the globe using solar energy in 2011.
C. The solar panels in Planet Solar can turn more sunlight to energy than average ones.
D. Batteries aboard Planet Solar can be consumed for at most three days of cloudy weather.
60. What is the main idea of the passage?
A. Planet Solar uses solar energy all over the world.
B. Planet Solar aims to be the first to circle the globe.
C. Planet Solar collects a different kind of renewable energy.
D. Planet Solar combines traditional methods with modern technology.

The ocean bottom, a region nearly 2．5 times greater than the total land area of the Earth, is even today largely unexplored．Until about a century ago, the deep-ocean floor was completely inaccessible and hidden beneath waters averaging over 3,600 meters deep．Totally without light and subjected to intense pressures hundreds of times greater than at the Earth’s surface, the deep-ocean bottom is a strangeenvironment to humans, in some ways as forbidding and remote as the outer space．
Although researchers have taken samples of deep-ocean rocks for over a century, the first detailed global study of the ocean bottom did not actually start until 1969, with the beginning of the National Science Foundation’s Deep Sea Drilling Project(DSDP)．Using techniques first developed for the offshore oil and gas industry, the DSDP’ s drill ship, the Glomar Challenger, was able to maintain a steady position on the ocean’s surface and drill in very deep waters, taking samples of  rock from the ocean floor．
The Glomar Challenger completed 96 voyages in a 15-year research program that ended in November 1983．During this time, it sailed 600,000 kilometers and took almost 20,000 samples of rocks aroun d the world．Those samples have allowed geologists to reconstruct what the planet looked like hundreds of millions of years ago and to make out what it will probably look like millions of years in the fu ture, Today, largely on the strength of evidence gathered during the Glomar Challenger’ s voyages, nearly all earth scientists agree on the theories of plate tectonics （構(gòu)造學(xué)）and continental drift that explain many of the geological processes．
The samples of rocks drilled by the Glomar Challenger have also provided a climatic record stretching back hundreds of millions of years．The information of past climatic change can be used to predict future climates．
68．What does the underlined word “inaccessible” in line 3 means?
A．unrecognizable     B．unreachable       C．unusable        D．unreasonable
69．Why does the author mention “outer space” in the first paragraph?
A．The Earth’s climate millions of years ago was similar to that in outer space．
B．It is similar to the ocean floor in being strange to the humans．
C．Rock formations in outer space are similar to those found on the ocean floor
D．Techniques used by scientists to explore outer space were similar to those used in ocean exploration
70．Which of the following is true of the Glomar Challenger?
A．It is a type of submarine．               B．It is an ongoing project．
C．It has gone on over 100 voyages．        D．It made its first DSDP voyage in 1968．
71．Which of the following is NOT mentioned in the passage as being a result of the Deep sea Drilling Project?
A．Geologists were able to determine the Earth’s appearance millions of years ago．
B．Two geological theories became more widely accepted by scientists．
C．Geologists observed forms of life never before seen
D．Information was revealed about the Earth’s past climatic changes．

　In a great many cities, hundreds of people ride bicycles to work everyday. In New City, some bike riders have even formed a group called Bike for a Better City. They declare that if more people rode bicycles to work, there would be fewer automobiles(汽車) in the downtown part of the city and so less dirty air from car engines. For several years this group has been trying to get the city government to help bicycle riders. For example. They want the city to draw special lanes(通道) for bicycles only on some of the main streets, because when bicycle riders must use the same lanes as cars, there are accidents. Bike for a Better city feels that if there were special lanes more people would use bikes.
But no bicycles lanes have been drawn. Not everyone thinks they are a good idea-----they say it will slow traffic. Some store owners on the main streets don't like the idea------they say that if there is less traffic, they will have less business.
The city government has not yet decided what to do. It wants to keep everyone happy. On weekends, Central Park----the largest place of open ground in New York----is closed to cars, and the roads may be used by bicycles only. But Bike for a Better City says that this is not enough and keeps fighting to get bicycle lanes downtown.
73. The bike riders suggest that _____________.
A. bicycles should be used instead of cars    B. bicycle lanes should be drawn
C. fewer buses or cars should be used  D. the number of special lanes should be increased
74. The advantage(好處) of the special lanes is that _______.
A. they will make cars and buses run slowly   B. they will make it easier for bike riders to go to parks
C .they will make the city more beautiful    D. the lanes will prevent accidents
75. The government has not decided whether special lanes should be drawn ______.
A. so that everyone is disappointed      B. because there are different opinions
C. because most people travel by train   D. because Bike for a Better City is not strong enough

Increasing affluence（富裕）and currency appreciation are behind the spike in Chinese students traveling abroad for their undergraduate studies, industry insiders said.
The Ministry of Education last month reported that a record 840,000 high school graduates did not register for the gaokao (university entrance exam) this year. Those numbers are fueling speculation that this was due to the increasing number of Chinese students wanting to study abroad.
The total number of students traveling abroad to study increased from 144,000 in 2007 to 170,000 last year. This figure will probably top 200,000 this year, said Feng Jishang, marketing manager of Wiseway, a consulting firm that advises students and their parents about overseas schools.
Years ago, most Chinese students who went abroad would first complete their undergraduate studies in China before applying to an overseas graduate school. But this traned is changing. According to industry estimates, the proportion of students seeking their first degree abroad has risen to 30 to 50 percent of all overseas-bound students. That means there could be as many as 60,000 to 100,000 such students this year—— triple the number in 2003.
Foreign college campuses are beginning to notice the trend. A source tat the University of San Francisco told China Business Weekly that the campus used to accept three or four Chinese undergraduate students every year. Today, the number has hit 80, the university source said.
Rapid economic growth, coupled with a currency that has risen by more than 20 percent against the US dollar over the last four years, is making an overseas education more affordable for Chinese students. That’s making US campuses such as the University of San Francisco, or USF, more of a bargain. “ Students used to tell me that they did not have the money to go to USF, and they needed full scholarships. That is not the case now,” said Stanley Nel, vice-president of international relations at the San Francisco campus.
Another reason is that there simply aren’t enough places in Chinese colleges, especially the higher-rated ones, to satisfy the demand for a university education. “ Four in ten students taking the gaokao won’t get university places. Furthermore, of those that do many don’t get into the schools of their choice. That is why more are going abroad,” Feng of Wiseway said.
A widespread perception among students is that going overseas for college improves their career prospects, sources said. “ For Chinese students, capability is not a problem, but they need work experience and communication skills,” said Alan McNeilly, assistant dean at Teeside University in the United Kingdom. “ If they get a degree overseas, they can expect higher salaries and better positions when they return,” McNeilly said. His university will set up an office in China next month to attract more students, Mc Neilly added.
1.More and more Chinese students have recently traveled abroad for studines because______.
A．they don’t want to take part in the gaokao
B．most Chinese students want to study abroad
C．many Chinese people become richer and US dollar has been devalued
D．it is easy to complete their undergraduate studies
2.Which of the following statistics-related statements is NOT true?
A．The number of students seeking their first degree abroad is around 20,000 to 33,000 in 2003.
B．The increment of the total number of students traveling abroad to study is probably bigger from 2008 to 2009 than that from 2007to 2008.
C．The number of Chinese undergraduate students accepted at USF is about 20 to 26 times of that in the past.
D．200,000 out of the 840,000 high school graduates who did not take the gaokao this year started their undergraduate study abroad.
3.Students interested in studying abroad take the following factors into account EXCEPT_____.
A．financial affordability    
B．work opportunities after graduation
C．a(chǎn)ccommodation standard
D．the chance of getting into a more desirable university
4.What can be inferred from this passage?
A．If the Chinese RMB decreases 20 percent against the US dollar, the number of Chinese students traveling abroad to study will decrease 20 percent.
B．If more universities are established in China, fewer students will choose to study abroad.
C．Teeside University will set up an office in China to attract those students who have been admitted to USF but have not been offered full scholarships.
D．Without a degree overseas higher salaries and better positions are not impossible if you are experienced and have outstanding communication skills.
