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

People often have troubles getting used to a new culture. They are usually curious when they first arrive a foreign country. Therefore, if they stay for a long time, they may start to feel different stages of culture shock. They can feel alone or sad because he can’t deal with the local people. How quick people get used to culture differences may be depend on the way they learn. That’s a problem if they can’t speak the language. On other hand, some can study the situation and make good guesses about the culture. When they finally began to understand some of the language and make some new friends, they will gradually enjoy themselves and feel satisfying.

It is interesting how NASA(美国航空航天管理局)chose their astronauts for landing them on the moon. They chose men  26  the age of twenty and thirty-five. There were about fifty of them, Many were  27  air pilots.  28 were scientists with two or three degrees. NASA telephoned each man they were going to choose; told him the plans and the  29  they might get in. They then asked him if he was willing to be trained as an astronaut. “How could any man  30 such an exciting job?” One of them said, “Dangerous? Of course. It’s dangerous  31 most exciting”

The health and physical condition of  32 was, of course, very necessary.  33  those in very good health and physical condition were chosen.

While being trained to be astronauts. They went through many  34 . They studied the star and the moon, and they also studied geology, the science of rocks. This was necessary  35  astronauts would have to look for rocks on the moon. They would try to find rocks which might help to tell the  36 of the moon. They were all  37 to fly in helicopters （直升飞机）。These helicopters landed  38 down to give them some experience of the way the spaceship would  39 land on the moon , They were also taught the  40  facts about the conditions in space. They learnt all the technical details of the spaceships and rockets. They visited the scientists and engineers who  41 them. They visited the factories where they were  42. They learnt how every 43 of a space-ship and its instruments work. They also learnt every detail of ground-control  44 .

In a word, to be chosen as an astronaut. One must be in good health,  45  in science and good at piloting.

　Parents often believe that they have a good relationship with their teenagers. But last summer, Joanna and Henry noticed a change in their older son: suddenly he seemed to be talking far more to his friends than to his parents. “The door to his room is always shut.” Joanna noted.

Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up (蜷伏)with me on the sofa and talk,” said Mark. “Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a little girl and sometimes like a young lady. The problem is figuring out which time is which.”

Before age 11, children like to tell their parents what’s on their minds. “In fact, parents are first on the list.” said Michael Riera, author of Uncommon Sense for Parents with Teenagers. “This completely changes during the teen years.” Riera explained. “They talk to their friends first, then maybe their teachers, and their parents last.”

Parents who know what’s going on in their teenagers’ lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young. Another thing parents should remember is that to be a friend, not a manager, with their children is a better way to know them.

“The door to his room is always shut” suggests that the son          .

 A．keeps himself away from his parents  

B．doesn’t want to be disturbed

 C．is always busy with his studies      

D．begins to dislike his parents

What troubles Tina and Mark most is that       .

 A．their daughter isn’t as lovely as before

 B．they don’t know what to say to their daughter

 C．they can’t read their daughter’s mind exactly

 D．their daughter talks with them only when she needs help

 A．Teenagers do not talk much with their parents.

 B．Teenagers do not want to understand their parents.

 C．Teenagers talk a lot with their friends.

 D．Teenagers talk little about their own lives.

．What can be learned from the passage?

 A．Parents are unhappy with their growing children.

 B．Parents have suitable ways to talk with their teenagers.

 C．Parents should try to understand their teenagers.

 D．Parents should be patients with their silent teenagers.

It is common and usual to see people freak out when they face challenges in their life. We all pass in different life problems and challenges. No one is free of life problems. Only a dead man faces no problem. As long as you are alive, challenges are everywhere.

How do you face problems and challenges in your life? Problems and challenges are the building blocks of your personality. They make you who you are. Besides, whether what happened in your life builds or destructs you depends on how you look at it. If you take your problems as troubles, they will be troubles and may cause destruction. If you take them as constructive tools, you are going to be built up on them.

Problems are everywhere. No one can avoid them. And they are good too. They open up a different look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as well as bad sides. Focus on the good one. Look at the bright side.

Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right beside you who can turn everything into your best if you are willing to turn to them. No matter what happens, they will be there to help you. Trust them and they will never let you down. All you need to know is that you are loved wherever you are.
