A California family drives a car that could help protect the environment. When Jon and Sandy go to the store or to their daughters’ soccer games, they drive in high-tech style. They drive a $1 million, fuel-cell-powered car. It may be the world’s most expensive car and one of the most environmentally friendly cars. The FCX is the first fuel-cell-powered car to be used by a family anywhere in the world. The FCX uses hydrogen and oxygen for fuel. Car makers have been working to develop vehicles that are better for the environment. They are developing cars that use fuel other than gasoline. And then what is fuel cell technology? Fuel cell technology works by changing the chemicals hydrogen and oxygen into water. This process produces electricity, and water vapor which comes out of the exhaust pipe. Most cars release dangerous gases such as carbon monoxide and carbon dioxide. Many scientists say these gases are major contributors to global warming. “The FCX is driven just like any other vehicle on the road, but without the gases which pollute the environment,” scientists say. Fuel cell technology has been around since the 1800s, but scientists have yet been to perfect it. They say it may take years before the technology is ready for widespread use. Another earth-friendly car is already on the market. Hybrid cars use both gasoline and an electric motor. They are becoming more popular with customers because they cut pollution and improve fuel efficiency.

When it comes to human resources, hiring highly-skilled staff is not usually enough for a company to function successfully. Besides the knowledge in their particular fields, employees must always have additional skills-----those of co-operation. In the case that work tasks can only be carried out by communicating with people, accepting common decisions, solving problems, sharing information and helping one another, teamwork skills are important.
While some jobs may require talent, the ability to work as a team is learned. There are no complicated formulas(规则); you don't need to have any special qualities or exceptional mental abilities. Individuals can be effective as a team if they have developed certain behaviors or habits of communication. Many companies, clubs and organizations use team building activities. Team building activities may include a number of teamwork elements. They are aimed at encouraging active participation in task accomplishment while all members have their roles as individuals and are able to co-operate towards a common goal as a team.
Many team building activities focus on problem solving and discussing team issues; thus argument as a way to common consensus (共识) is encouraged. Team building activities often involve recognition and identification of team member skills, talents, knowledge, and experiences which allow the team members to learn more about each other and fully utilize (利用) those skills where appropriate（合适的）. Many team activities are focused on developing keys to trust during challenging times.In the author's opinion, which of the following is important for a company to be successful?
| A．Specialized knowledge. | B．Highly-skilled staff. |
| C．Exceptional talent. | D．Teamwork skills. |

In Canada you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends. Before they keep them in their houses, they take them to animal hospitals to give them injections(注射) so that they won’t carry diseases. They have special animal food stores, though they can get animal food in almost every kind of stores. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people’s houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals. If you killed an animal, you would be punished. If an animal happened to get run over by a car, people would be very sad about it.
People in Canada have many reasons to like animals. One of them might be: Their family ties are not as close as ours. When children grow up, they leave their parents and start their own life.

“Well, what did I say？Buck’s a real fighter, all right,” said Francois the next morning when he discovered that Spitz had disappeared and that Buck was covered in blood．
“Spitz fought like a wolf,” said Perrault, as he looked at the bites all over Buck．
“And Buck fought like ten wolves,” answered Francois. “And we'll travel faster now. No more Spitz，no more trouble.”
Francois started to harness the dogs. He needed a new lead-dog, and decided that Solleks was the best dog that he had. But Buck jumped at Solleks and took his place．
“Look at Buck！” said Francois，laughing. “He's killed Spitz，and now he wants to be lead-dog．Go away, Buck！”
He pulled Buck away and tried to harness Solleks again．Solleks was unhappy too. He was frightened of Buck, and when Francois turned his back，Buck took Solleks’ place again. Now Francois was angry．
“I'll show you! ” he cried，and went to get a heavy club from the sledge．
Buck remembered the man in the red coat，and moved away. This time，when Solleks was harnessed as lead-dog，Buck did not try to move in．He kept a few meters away and circled around Francois carefully. But when Francois called him to his old place in front of Dave, Buck refused．He had won his fight with Spitz and he wanted to be lead－dog．
For an hour the two men tried to harness him．Buck did not run away，but he did not let them catch him．Finally，Francois sat down，and Perrault looked at his watch．It was getting late. The two men looked at one another and smiled. Francois walked up to Solleks，took off his harness， led him back and harnessed him in his old place．Then he called Buck. All the other dogs were harnessed and the only empty place was now the one at the front. But Buck did not move．
“Put down the club,” said Perrault．
Francois dropped the club, and immediately Buck came up to the front of the team．Francois harnessed him, and in a minute the sledge was moving．
Buck was an excellent leader. He moved and thought quickly and led the other dogs well. A new leader made no difference to Dave and Solleks; they continued to pull hard．But the other dogs had had an easy life when Spitz was leading．They were surprised when Buck made them work hard and punished them for their mistakes. Pike，the second dog，was usually lazy；but by the end of the first day he was pulling harder than he had ever pulled in his life. The first night in camp Buck fought Joe，another difficult dog，and after that there were no more problems with him．The team started to pull together，and to move faster and faster．
“I've never seen a dog like Buck!” cried Francois, “Never! He's worth a thousand dollars. What do you think, Perrault? ”
Perrault agreed．They were moving quickly，and covering more ground every day. The snow was good and hard，and no new snow fell．The temperature dropped to 45°C below zero, and didn't change．
This time there was more ice on the Thirty Mile River, and they crossed in a day．Some days they ran a hundred kilometers，or even more. They reached Skagway in fourteen days; the fastest time ever．The writer mentioned “the man in the red coat” in the passage to show that____.

It is common to have difficulties sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift（轮班）work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap（小睡）. When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much on weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications（药物治疗）may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed. The purpose of the text is to.
| A．persuade workers to have a god sleep. |
| B．advise night workers to keep healthy |
| C．encourage workers to do day work |
| D．help night workers to sleep well |
What does the author recomusend?
| A．A suitable account of alcohol to help sleep. |
| B．A regular life on weekday’s and weekends. |
| C．A dark room without phoebes to sleep in. |
| D．A break for sleeping anytime during the day. |
On which condition should a person turn to a sleep specialist for help?
| A．If he suffers from a sleep disorder for the first time. |
| B．If a good sleep environment is greatly needed for him. |
| C．If he falls to get quality sleep through his own efforts. |
| D．If he has the problem of bailing to sleep in the daytime. |
We can learn from the test that.
| A．night workers need a long time to fall asleep |
| B．constant breaks at work help to improve performance |
| C．it is difficult to create a good sleep environment |
| D．night work requires people to adjust their body clocks |
In the computer age, most of us take a broadband（宽带）Internet connection for granted. Whether cable or mobile broadband, today’s connections are many times faster than those in the early days. Videos play smoothly, complex websites load quickly, and files（档案文件）download much faster than ten years ago. And the files are much bigger too.
There’s a catch, of course: You have to live near enough to a major city to get broadband Internet. If you don’t, it’s slow dial-up access for you. And for those living really far out, there may be no Internet access at all.
Technology experts often talk about the “last mile” problem, which refers to the difficulty of bringing Internet access to remote locations. In cities and suburbs（郊区）, it’s relatively easy to provide access for everyone. It is much more difficult to deliver access to those living far from cities, especially in developing countries. Internet service providers, for their part, have been reluctant to provide access to sparsely (稀疏地) populated areas. The handful of Internet users they would reach wouldn’t cover the expense.
But every year, technological advancements allow of more and more Internet users. Most broadband connections today run over existing cable TV and telephone lines although these technologies aren’t available everywhere.
Some companies have delivered the Internet over standard power lines. Advancements in cheaper, more efficient fiber optics cables (光纤电缆) promise to bring extremely fast Internet connections to more users.
Still, the “last mile” problem remains hard to deal with. There will always be somewhere that doesn’t have an affordable broadband connection. But someday that might not matter. If the rapid progress in cell phone technology is any indication (迹象), it may not be too long before an Internet connection simply follows you wherever you go.The underlined part “a catch” (in Paragraph 2) probably means “_____”.
| A．a rare challenge | B．a desirable plan |
| C．an efficient device | D．a hidden problem |
What can we know from the third paragraph?
| A．Internet connection has not been popular in most cities. |
| B．Internet service providers care about rural（农村的）customers. |
| C．Computer is popular in developing countries. |
| D．It is hard to bring Internet access to users in remote areas. |
Paragraph 4 mainly tells us that technological advancements _____.
| A．make TV and telephone available everywhere |
| B．bring great change to people’s everyday life |
| C．make it possible for more people to use the Internet |
| D．bring faster Internet connections to users |
What may eventually settle the “last mile” problem?
| A．The broadband connection’s getting faster. |
| B．More and more Internet users. |
| C．more and more Internet connections. |
| D．The rapid progress in cell phone technology. |
