When did you last see a polar bear? 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 bit 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 through February.
Doctors do not agree about the medical effects of cold-water swimming. Some are worried about the dangers of a condition in which the body’s temperature drops so low that finally the heart 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 (or advantages) 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 (or advantages) of cold-water swimming are probably mental. The Polar Bears love to swim year-round; they find it fun and relaxing. As one 70-year-old woman says, “When I go into the water, I pour my troubles into the ocean and let them float away.”The members of the Polar Bear Club must meet the following requirements except that ______.
| A．they must reach the age of 60 |

The Pacific island nation of Nauru used to be a beautiful place. Now it is an ecological disaster area. Nauru's heartbreaking story could have one good consequence-other countries might learn from its mistakes.
For thousands of years, Polynesian people lived on the remote island of Nauru, far from western civilization. The first European to arrive was John Fearn in 1798. He was the British captain of the Hunter, a whaling ship. He called the island Pleasant Island.
However, because it was very remote, Nauru had little communication with Europeans at first. Then whaling ships and other traders began to visit, bringing guns and alcohol. These elements destroyed the social balance of the twelve family groups on the island. A ten-year civil war started, which reduced the population from 1，400 to 900.
Nauru's real troubles began in 1899 when a British mining company discovered phosphate（磷酸盐）on the island. In fact, it found that the island of Nauru was nearly all phosphate, which is a very important fertilizer for farming. The company began mining the phosphate.
A phosphate mine is not a hole in the ground; it is a strip mine. When a company strip-mines, it removes the top layer of soil. Then it takes away the material it wants. Strip-mining totally destroys the land. Gradually, the lovely island of Nauru started to look like the moon.
In 1968，Nauru became one of the richest countries in the world. Every year the government received millions and millions of dollars for its phosphate.
Unfortunately, the leaders invested the money unwisely and lost millions of dollars. In addition, they used millions more dollars for personal expenses. Soon people realized that they had a terrible problem-their phosphate was running out. Ninety percent of their island was destroyed and they had nothing. By 2000，Nauru was al-most financially ruined. Experts say that it would take approximately$433，600，000 and more than 20 years to repair the island. This will probably never happen.What might be the author's purpose in writing the text?
| A．To seek help for Nauru's problems. |
| B．To give a warning to other countries. |
| C．To show the importance of money. |
| D．To tell a heartbreaking story of a war. |
What was Nauru like before the Europeans came?
| A．Rich and powerful. |
| B．Modern and open. |
| C．Peaceful and attractive. |
| D．Greedy and aggressive. |
The ecological disaster in Nauru resulted from __________.
| A．soil pollution |

There's no need to say it, but there are really more than a few benefits to educational tours. From the word itself, an educational tour is something done to gain knowledge while traveling and touring to some place. It creates opportunities for people to think out of the box and see things and places that aren't usually seen in their normal environment.
Educational trips aren't always those that cover far distances. As already said, it is done to gain knowledge and you wouldn't need to go very far to have it. Sometimes, an educational trip could be in your hometown.
Historic places and museums are always on top of the lists of the places to go in an educational tour. Educational tours like these would make you know your country better. Your country's history is rich and it is the reason why you came. But remember that the history of other states, counties and countries are as important as your own.
When you go on a trip to another country, it is likely that you learn their culture first. Different cultures have different understanding and perspective of different acts, and it could be dangerous or offending if you cannot understand a culture.
When you go on an educational tour, it is likely that you would have the opportunity to socialize with other people. Students are encouraged to talk to locals and natives and learn from them, because it is with understanding that students gain knowledge. When students talk with local people, they are gaining insights to their life and their culture. It is said that when in Rome, act and think as the Romans do, and this is a valuable skill that not all people could do.
There are millions of people who want to travel, and an educational tour is the perfect time to do so. Traveling opens new doors and opportunities; it always makes you want to learn more. Cultures are many and widely different, and it is a very valuable talent to understand the people of different cultures.
Traveling with groups of other students is safer than traveling alone, and bulk travels like those could also be helpful on the budget. Group of friends could stay at one place and get discounts on the place that you wouldn't get if you are traveling alone. Traveling is fun and more budget-friendly when with other people on an educational tour.
Travel abroad for a month, try and see if you wouldn't miss your own country. Traveling would let you see your own country in a different way. The benefits of an educational tour are all important, but this one creates patriotism in a person.
A school isn't a place where they teach you to find the answers; it is a place where one teaches you to find the questions and learn the answers for yourself. Educational tours are valuable this way.

As she was looking, a little boy came to the Pokemon toys. He was dressed neat-ly, but his clothes were obviously old. He was with his father as well, and kept picking up the Pokemon video toys. Each time he picked one up and looked at his father, his father shook his head and said，"No. "
The little girl had chosen her Barbie. However, she stopped and was watching them. Rather dejectedly, the boy had to give up the Pokemon toys and choose something else.

"Daddy, didn't grandparents want me to buy something that would make me happy?" He said，"Of course they did, honey. " To which the little girl replied，" Well, I just did ！"

When you're surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?
