阅读短文,完成问题。

Happiness and sadness are states of being that define the way we view the world. It is often said that some people by nature have a sunny character. Now scientists may have discovered why.

Some people may be born for happiness, while others are genetically negative, scientists have suggested in a study published late February in a British journal.

Earlier research had already established that the gene known as 5-HTTLPR plays a key role in determining how the neurotransmitter (神经传递素) serotonin (含于血液中的复合胺) works within the brain. Serotonin, a hormone (荷尔蒙), passes chemical messages between nerve cells. It has been closely linked to mood. Several anti-depressant (抗抑郁) drugs regulate serotonin levels. Scientists had also identified three variants (变体) of the gene. Two so-called "short" variants were linked to a higher risk of depression and suicide attempts. Unlike the two "short" variants, the "long" variant of 5-HTTLPR showed a clear dislike of negative images, such as fierce animals, and a clear liking for positive ones, such as flowers.

Researchers from the University of Essex in Britain, led by Elaine Fox, showed participants a series of images. The images were divided into three kinds: negative ones aimed at inspiring fear or stress such as a spider or person about to commit suicide, pleasant ones and neutral (中性的) ones. The participants who had the long variant of the 5-HTTLPR gene "showed a clear dislike of negative material alongside a careful attention for positive material," the researchers found. They paid close attention to the pretty pictures, and ignored the frightening ones. On the other hand, the short variant groups had the opposite reaction.

In January, the Australian government organized "happiness workshops", teaching government staff how to be happy. The department that held the "happiness workshops" said unhappy staff weren't productive staff. Australian political opposition parties have argued that the "happiness workshops" are probably a waste of money and couldn't increase productivity as intended. However, whether the workshop will have a happy or disappointing result, we will have to wait and see.

1. For the passage,by what means can we view the world?

A. Happiness and sadness.                                        B. Happiness and curiosity.

C. Sadness and amazement.                                      D. Disappointment and sadness.

2. What is most important in the role of deciding how the the neurotransmitter serotonin works within the brain?

A. The gene known as 5-HTTLPR.                            B. Three variants.

C. Neurotransmitter serotonin       .                                  D. A hormone.

3 Which of the following sentences is WRONG?

A. Serotonin, a hormone within the brain., passes chemical messages between nerve cells, which has been closely linked to mood.                              

B. Scientists identified the two "short" variants, and the "long" variant of 5-HTTLPR which showed a clear hatred of negative images, such as fierce animals.  

C. Scientists identified three variants of the gene. Two so-called "long" variants were linked to a higher risk of depression and murder attempts.                     

D. In terms of researchers’ research, the images were divided into three kinds: negative ones, pleasant ones and neutral ones.  

4. Why did the Australian government organize “Happiness workshops”?

A. To enrich staff’s free life.                                 

B. To teach staff the ways to be happy.

C. To prove the result of the researchers’ research.     

D. To test who weren’t productive staff.

5. What is the result of setting up “Happiness workshops” according to the last paragraph?

A. A waste of money.                                              

B. No effect on increasing productivity.

C. A disappointing result       .                                 

D. An uncertain result.

Equipped only with a pair of binoculars (双筒望远镜) and ready to spend long hours waiting in all weathers for a precious glance of a rare bullfinch(红腹灰雀). Britain’s birdwatchers had long been supposed to be lovers of a minority sport. But new figures show birdwatching is fast becoming a popular pastime, with almost three million of us absorbed in our fluttering feathered friends.

Devoted birdwatchers, those prepared to travel thousands of miles for a sighting of a rare Siberian bird, are fast being joined by a new breed of follower whose interest is satiated by watching a few finches (雀科鸣鸟) on a Sunday walk or putting up a bird-box in the back garden.

 “Almost three million UK birdwatchers is certainly possible if you include everyone with only a casual interest,” Stephen Moss said in his newly published book—A Bird in the Bush: a Social History of Birdwatching—which records the pursuit from the rich Victorian Englishman’s love of shooting rare birds to the less offensive observational tendencies of birdwatchers today.

Television wildlife programmes have helped to fuel the new trend. Last summer, BBC 2’s Britain Goes Wild was a surprise success. It pulled in three million viewers and led to bird-houses selling out across the UK as 45,000 people promised to put up a box.

Birdwatchers’ networking system first came to the attention of the nation in 1989, when a birdwatcher caught sight of the first Vermivora chrysoptera—a golden-winged songbird from North America—to be seen in Britain. He put a message out on the network service Birdline, and the next day 3,000 birdwatchers proved the full pull of a truly rare bird as they visited the Tesco car park in Kent, where it had settled. Today, birdwatchers can log on to www.birdline.co.uk or have news of the latest sightings texted to their phones.

 “Multimillion-pound spending on binoculars, bird food and boxes point to the increasing numbers of birdwatchers,” said David Cromack, the editor of Bird Watching magazine, “The number of people involved is so big that they have great potential to influence government decisions affecting the environment.”

The word “satiated” in paragraph 2 can best be replaced by “_______”.

A. affected     B. shared       C. satisfied     D. narrowed

What happened after the message of seeing a Vermivora chrysoptera was put on the network?

   A. Birdwatchers helped the rare bird settle in Kent.

   B. Large numbers of birdwatchers went to view the bird.

   C. Many birdwatchers logged on to the website for details.

   D. Birdwatchers showed their determination to protect the rare bird.

Which of the following CANNOT be true according to the passage?

   A. Television wildlife programmes started the popular pastime of birdwatching.

   B. The network service has contributed to the rapid development of birdwatching.

   C. Birdwatching in Britain was long considered a sport with a small group of followers.

   D. The current situation of birdwatching may promote the protection of the environment.

The passage mainly tells us about ________ in UK.

   A. the history of bird watching    

   B. a growing passion for bird watching

   C. the impact of media on bird watching  

   D. bird watching as a popular expensive sport

Thirteen vehicles lined up last March to race across the Mojave Desert, seeking a million in prize money. To win, they had to finish the 142-mile race in less than 10 hours. Teams and watchers knew there might be no winner at all, because these vehicles were missing a key part -drivers.

DARPA, the Defense Advanced Research Projects Agency, organized the race as part of a push to develop robotic vehicles for future battlefields. But the Grand Challenge, as it was called, just proved how difficult it is to get a car to speed across an unfamiliar desert without human guidance. One had its brake lock up in the starting area. Another began by throwing itself onto a wall. Another got tied up by bushes near the road after 1.9 miles.

One turned upside down. One took off in entirely the wrong direction and had to be disabled by remote (远距离的) control. One went a little more than a mile and rushed into a fence; another managed to go for six miles but stuck on a rock. The “winner,” if there was any, reached 7.8 miles before it ran into a long, narrow hole, and the front wheels caught on fire.

“You get a lot of respect for natural abilities of the living things,” says Reinhold Behringer, who helped design two of the car-size vehicles for a company called Sci-Autonics. “Even ants (蚂蚁) can do all these tasks effortlessly . It’s very hard for us to put these abilities into our machines.”

The robotic vehicles, though with necessary modern equipment such as advanced computers and GPS guidance, had trouble figuring out fast enough the blocks ahead that a two-year-old human recognizes immediately, Sure, that very young child, who has just only learned to walk, may not think to wipe apple juice off her face, but she already knows that when there’s a cookie in the kitchen she has to climb up the table, and that when she gets to the cookie it will taste good. She is more advanced, even months old, than any machine humans have designed.

Watchers doubted if any of the vehicles could finish the race because        .

A.they did not have any human guidance

B.the road was not familiar to the drivers

C.the distance was too long for the vehicles

D.the prize money was unattractive to the drivers

DARPA organized the race in order to         .

A.raise money for producing more robotic vehicles

B.push the development of vehicle industry

C.train more people to drive in the desert

D.improve the vehicles for future wars

From the passage we know “robotic vehicles” are a kind of machines that         .

A.can do effortlessly whatever tasks living thing can

B.can take part in a race across 142 miles with a time limit

C.can show off their ability to turn themselves upside down

D.can move from place to place without being driven by human beings

In the race, the greatest distance one robotic vehicle covered was          .

A.about eight miles    B.six miles

C.almost two miles     D.about one mile

In the last paragraph, the writer implies that there is a long way to go         .

A.for a robotic vehicle to finish a 142-mile race without any difficulties

B.for a little child who has just learned to walk to reach the cookie on the table

C.for a robotic vehicle to deal with a simple problem that a little child can solve

D.for a little child to understand the importance of wiping apple juice off its face

“If there is one thing I’m sure about, it is that in a hundred years from now we will still be reading newspapers. It is not that newspapers are a necessity. Even now some people get most of their news from television or radio. Many buy a paper only on Saturday or Sunday. But for most people reading a newspaper has become a habit passed down from generation to generation.

The nature of what is news may change. What basically makes news is what affects our lives — the big political stories, the coverage of the wars, earthquakes and other disasters, will continue much the same. I think there will be more coverage of scientific research, though. It’s already happening in areas that may directly affect our lives, like genetic(基因) engineering. In the future, I think there will be more coverage of scientific explanations of why we feel as we do — as we develop a better understanding of how the brain operates and what our feelings really are.

It’s quite possible that in the next century newspapers will be transmitted(传送)  electronically from Fleet Street and printed out in our own home. In fact, I’m pretty sure that how it will happen in the future. You will probably be able to choose from a menu, making up your own newspaper by picking out the things you want to read — sports and international news, etc.

I think people have got it wrong when they talk about competition between the different media(媒体). They actually feed off each other. Some people once foresaw that television would kill off newspapers, but that hasn’t happened. What is read on the printed page lasts longer than pictures on a screen or sound lost in the air. And as for the Internet, it’s never really pleasant to read something just on a screen. 

What is the best title for the passage?

A. The Best Way to Get News                    B. The Changes of Media

C. Make Your Own Newspaper                  D. The Future of Newspaper

In the writer’s opinion, in the future, _______. 

A. more big political affairs, wars and disasters will make news

B. newspapers will not be printed in publishing houses any longer

C. newspapers will cover more scientific research

D. more and more people will watch TV

What will probably be on in the newspaper made by yourself?

A. Sports and international news.               B. A menu of important news.

C. The most important news.                     D. What you are interested in.

From the passage, we can infer _______. 

A. newspapers will win the competition among the different media

B. newspapers will stay with us together with other media

C. television will take the place of newspaper

D. the writer believe some media will die out

The phrase “feed off” in the last paragraph means _______. 

A. depend on                                     B. compete with

C. fight with                                     D. kill off
