　　Where did you see a polar bear? At 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 best 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 favourite form of exercise is very good for the circulatory system （循環(huán)系統(tǒng)） 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 the 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.”

1．Which of the following is NOT necessary for members of the Polar Bear Club? ________.

[　　]

A．They should be easy to make friends with

B．They must swim outdoors at least 8 times in the four cold months

C．They must agree to swim outdoors from November through February

3．According to the passage, some doctors believe it is true that ________.

[　　]

A．you are healthy if cold-water swimming turns your skin color blue

B．there is more danger of a heart attack during summer swimming

C．cold-water swimming can make the body temperature dangerously high

D．Polar Bears are bears swimming in freezing water

[　　]

A．they can remain young

When someone says “SHARK” most people think of a big, toothy, underwater animal; basically we are imagining a Great White. In fact sharks come in all shapes, sizes and even colors! Follow me please; I’d like to show you a very special small shark commonly known as horn sharks, only found in the coastal waters of north-west North America.

Look at this shark, and you can easily see the horns on it and you will know the reason why it is called the horn shark is that it has the broad, flattened head and two large horn-like spines(脊椎) found behind its eyes and makes it one of the hardiest of all shark species. What makes it unique is that as its enemy attempts to swallow it, the spines on its back will stick into the enemy’s mouth and give a good chance for it to get away.

The horn shark is brown in color with black spots all over its body. The adults can reach up to a length of 4 feet and weigh up to 10 kg. An interesting fact about the horn shark is that it has five gills(鰓). The horn shark is a clumsy swimmer using its flexible pectoral fins(胸鰭)to push itself along the bottom of the ocean. The maximum distance that has ever been recorded for a horn shark to have traveled out from its habitat is 10 miles.

Today, as so little is known about its population off the Californian coast, they have been listed as being “Data Deficient” in the World Conservation Union. The horn shark is being threatened both by water pollution and commercial fishing in the area. Though they are not among those sea creatures hunted primarily for food, but they often get caught as a by-catch in fishing expeditions.

1.The horn shark gets its name for______.

A. its small size                            B. its large eyes

C. its two large spines                       D. its brown color with spots

2.How is paragraph 3 mainly developed?

A. By giving descriptions                     B. By following time order

C. By analyzing causes                       D. By making comparisons

3.Which factors contribute to the horn shark’s being on the “Data Deficient” list?

①That people like hunting them for pets        ②That people fish them for fun

③Water pollution off the coast                ④Knowing little about them

A. ①②                B.②③            C. ①④            D.③④

4. According to the passage, all of the following are unique to the horn shark EXCEPT that_____.

A. it doesn’t travel far

B. it is good at swimming

C. its spines can be used to attack the enemy and escape

D. it is only found in the coastal waters of north-west North America
