When did you last see a polar bear(北极熊）?On a trip to a zoo,perhaps?If you had attended a winter
activity in New York a few years ago,you would have seen a whole polar bear club.These "Polar Bears" are people who meet frequently in the winter to swim in freezing cold water.That day,the air temperature was 3℃,and the water temperature was a little higher.The members of the Polar Bear Club at Coney Island,New York 
are usually about the age of 60.Members must satisfy two requirements.First,they must get along well with everyone else in the group;this is very important because there are so many different kinds of people in the club.Polar Bears must also agree to swim outdoors at least twice a month from November to February.
Dcotors don't agree about the medical effects of cold-winter swimming.Some are worried about the dangers of a condition in which the body's temperature d
rops so low that finally the hea
rt stops.Other doctors,however,point out that there is more danger of a heart attack during summer swimming because the difference between the air temperature and water temperature is much greater in summer than in winter.
The Polar Bears themselves are satisfied with the benefits of cold-water swimming.They say that their favorite form of exercise is very good for the circulatory system(循环系统）because it forces the blood to move fast to keep the body warm.Cold-water swimmers usually turn bright red after a few minutes in the water.A person who turns blue probably has a very poor circulatory system and should not try cold-water swimming.
The main benefits of cold-water swimming are probably mental.The Polar Bears love to swim all year round;they find it fun and relaxing.As one 70-year-old woman says,"When I go into water,I pour my troubles into the ocean and let them float away."

Margaret, married with two small children, has been working for the last seven years as a night cleaner, cleaning offices in a big building.
She trained as a nurse, but had to give it up when her elder child became seriously ill. “I would have liked to go back to it, but the shifts(工作班次) are all wrong for me, as I have to be home to get the children up and off to school.”
So she works as a cleaner instead, from 9 p．m. till 6 a．m. five nights a week for just ￡90, before tax and insurance. “It’s better than it was last year, but I still think that people who work ‘unsocial hours’ should get a bit extra.”
The hours she's chosen to work meant that she sees plenty of the children, but very little of her husband. However, she doesn't think that puts any pressure on their relationship.
Her work isn't physically very hard, but it's not exactly pleasant, either. “I do get angry with people who leave their offices like a place for raising pigs. If they realized people like me have to do it, perhaps they'd be a bit more careful.”
The fact that she's working all night doesn't worry Margaret at all. Unlike some dark buildings at night, the building where she works is fully lit, and the women work in groups of three. “Since I've got to be here, I try to enjoy myself——and I usually do, because of the other girls. We all have a good laugh, so the time never drags.”
Another challenge Margaret has to face is the reaction of other people when she tells them what she does for a living. “They think you're a cleaner because you don't know how to read and write，” said Margaret. “I used to think what_my_parents_would_say_if_they_knew_what_I'd_been_doing,_but I don't think that way any more. I don't dislike the work though I can't say I'm mad about it.”Margaret quit her job as a nurse because________
| A．she wanted to earn more money to support her family |
| B．she had suffered a lot of mental pressure |
| C．she felt tired of taking care of patients |
| D．she needed the right time to look after her children |
Margaret gets angry with people who work in the office because________.
| A．they never clean their offices |
| B．they look down upon cleaners |
| C．they always make a mess in their offices |
| D．they never do their work carefully |
When at work, Margaret feels________.
| A．Lighthearted because of her fellow workers |
| B．happy because the building is fully lit |
| C．tired because of the heavy workload |
| D．bored because time passed slowly |
The underlined part in the last paragraph implies that Margaret's parents would________.
| A．help care for her children |
| B．regret what they had said |
| C．show sympathy for her |
| D．feel disappointed in her |
Imagine, one day, getting out of bed in Beijing and being at your office in Shanghai in only a couple of hours, and then, after a full day of work, going back home to Beijing and having dinner there.
Sounds unusual, doesn't it? But it's not that unrealistic, with the development of China’s high-speed railway system. And that’s not all. China has an even greater high-speed railway plan— to connect the country with Southeast Asia, and eventually Eastern Europe.
China is negotiating to extend its own high-speed railway network to up to 17 countries in 10 to 15 years, eventually reaching London and Singapore.
China has proposed three such projects. The first would possibly connect Kunming with Singapore via Vietnam and Malaysia. Another could start in Urumqi and go through Kazakhstan and Uzbekistan, and possibly to Germany. The third would start in the northeast and go north through Russia and then into Western Europe.
If China’s plan for the high-speed railway goes forward, people could zip over from London to Beijing in under two days.
The new system would still follow China’s high-speed railway standard. And the trains would be able to go 346 kilometers an hour, almost as fast as some airplanes.
China’s bullet train (高速客车), the one connecting Wuhan to Guangzhou, already has the world’s fastest average speed. It covers 1,069 kilometers in about three hours.
Of course, there are some technical challenges to overcome. There are so many issues that need to be settled, such as safety, rail gauge (轨距), maintenance of railway tracks. So, it’s important to pay attention to every detail.
But the key issue is really money. China is already spending hundreds of billions of yuan on domestic railway expansion.
China prefers that the other countries pay in natural resources rather than with capital investment. Resources from those countries could stream into China to sustain development.
It’ll be a win-win project. For other countries, the railway network will definitely create more opportunities for business, tourism and so on, not to mention the better communication among those countries.
For China, such a project would not only connect it with the rest of Asia and bring some much-needed resources, but would also help develop China’s far west. We foresee that in the coming decades, millions of people will migrate to the western regions, where the land is empty and resources unused. With high-speed trains, people will set up factories and business centers in the west once and for all. And they’ll trade with Central Asian and Eastern European countries.China’s new high-speed railway plan will be a win-win project because _______.
| A．China will get much-needed resources and develop its western regions |
| B．China and the countries involved will benefit from the project in various ways |
| C．China will develop its railway system and communication with other countries |
| D．the foreign countries involved will develop their railway transportation, business and tourism |
According to the passage, the greatest challenge to the new high-speed railway plan is _______.
| A．technical issues | B．safety of the system |
| C．financial problems | D．maintenance of railway tracks |
Which of the following words best describes the author’s attitude towards China’s high-speed railway plan?
| A．Critical. | B．Reserved. | C．Doubtful | D．Positive. |
Along the river banks of the Amazon and the Orinoco there lives a bird that swims before it can fly, flies like a fat chicken, eats green leaves, has the stomach of a cow and has claws (爪) on its wings when young. They build their homes about 4.6m above the river, an important feature (特征) for the safety of the young. It is called the hoatzin.
In appearance, the birds of both sexes look very much alike with brown on the back and cream and red on the underside. The head is small, with a large set of feathers on the top, bright red eyes, and blue skin. Its nearest relatives are the common birds, cuckoos. Its most striking feature, though, is only found in the young.
Baby hoatzins have a claw on the leading edge of each wing and another at the end of each wing tip. Using these four claws, together with the beak (喙), they can climb about in the bushes, looking very much like primitive birds must have done. When the young hoatzins have learned to fly, they lose their claws.
During the drier months between December and March hoatzins fly about the forest in groups of 20 to 30 birds, but in April, when the rainy season begins, they collect together in smaller living units of two to seven birds for producing purposes.What is the text mainly about?
| A．Hoatzins in dry and rainy seasons. |

| A．They had claws to help them climb. |
| B．They could fly long distances. |
