Every day we go to school and listen to the teacher, and the teacher will ask us some questions. Sometimes, the classmates will ask for your opinions of the work of the class. When you are telling others in the class what you have found out about these topics, remember that they must be able to hear what you are saying. You are not taking part in a family conversation or having a chat with friends— they will remain silent, waiting to hear what you have to say. In the class, you must speak so that they can hear you—loudly enough and clearly enough but without trying to shout or appearing to force yourself.
Remember, too, that it is the same if you are called to an interview whether it is with a professor of your school or a government official who might meet you. The person you are seeing will try to put you at your ease (not worried) but the situation is somewhat different from that of an ordinary conversation. You must take special care that you can be heard.
41. Usually, when you speak to the class, the class is____________.
16．noisy B. quiet C. having a rest D. serious

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 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 through 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 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 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." The members of the Polar Bear Club must meet the following requirements except that_____.

Did you know that a turtle（乌龟）can lay 12 eggs in one minute? A large sea turtle lays around 150 eggs at a time. She lays all these eggs in just a few minutes.
Large sea turtles live in the warm seas of the world. Except for when they lay their eggs, they spend their whole lives in the water. When it is time to lay their eggs, the females(雌性) swim to land.
They usually return to the place where they themselves were born. How they find their way back there is unknown.
When they reach shore, the big, heavy turtles crawl slowly up to the high water mark. Using their flippers, they pull themselves along the sand. They must struggle like mountain climbers.
When they finally reach dry sand, they rest before beginning the difficult task of laying eggs.
