.—You are always full of _______.Can you tell me the secret?

—Taking plenty of exercise every day.

A. power       B. strength       C. force        D. energy

D


解析:

energy,power,strength和force均可表示“力”,但energy意為“能量”,尤指人在做某事并為完成該事所表現(xiàn)出的生機(jī)勃勃的力,多用作不可數(shù)名詞。You are always full of energy.表示“你總是精力充沛”。power意為“能力”,詞義豐富,可指內(nèi)在的或外加的力、潛在的或活動(dòng)的力、具體的或抽象的力、身體的或精神的力等。force意為“力”,常指促使物體運(yùn)動(dòng)的力,也可指勢力、武力或暴力,可用作可數(shù)名詞和不可數(shù)名詞。strength意為“體力”,常指人體或物體內(nèi)存在的力,如氣力、耐力、抵抗力,有時(shí)也可指進(jìn)行某種活動(dòng)的推動(dòng)力,是不可數(shù)名詞。

       Have you ever wondered why birds sing? Maybe you thought that they were just happy. After all ,you probably sing or whistle when you are happy.

       Some scientists believe that birds do sing some of the time just because they are happy. However ,they sing most of the time for a very different reason .Their singing is actually a warning to other birds to stay out of their territory.

       Do you know what a “territory” is? A territory is an area that an animal ,usually the male, claims(聲稱)as its own .Only he and his family are welcome there .No other families of the same species(物種)are welcome. Your yard and house are your territory where only your family and friends are welcome. If a stranger should enter your territory and threaten you, you might shout. Probably this would be enough to frighten him away.

       If so, you have actually scared the stranger away without having to fight him .A bird does the same thing. But he expects an outsider almost any time ,especially at nesting(筑巢)season. So he is screaming all the time, whether he can see an outsider or not .This screaming is what we call a bird’s song, and it is usually enough to keep an outsider away.

       Birds sing loudest in the spring when they are trying to attract a mate and warn others not to enter the territory of theirs.

       You can see that birds have a language all their own. Most of it has to do with attracting mates and setting up territories.

56.Some scientists believe that most of the time birds’ singing is actually       .

       A.a(chǎn)n expression of happiness                   B.a(chǎn) way of warning

       C.a(chǎn)n expression of anger                         D.a(chǎn) way of greeting

57.What is a bird’s “territory”?

       A.A place where families of other species are not accepted.

       B.A place where a bird may shout at the top of its voice.

       C.An area for which birds fight against each other.

       D.An area which a bird considers to be its own.

58.Why do birds keep on singing at nesting season?

       A.Because they want to invite more friends.

       B.Because their singing helps frighten outsiders away.

       C.Because they want to find outsiders around.

       D.Because their singing helps get rid of their fears.

59.How does the writer explain birds’ singing?

       A.By comparing birds with human beings.

       B.By reporting experiment results.

       C.By describing birds’ daily life.

       D.By telling a bird’s story.

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 (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

B. they should be easy to make friends with

C. they must swim outdoors at least 8 times in the four cold months

  D. they must agree to swim outdoors from November through February

Doctors __________.

A. encourage people to take part in cold-water swimming actively

  B. point out the possible danger of blood illness during cold-water swimming

  C. believe swimming is helpful both in winter and in summer

  D. have different ideas about the medical effects of cold-water swimming

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. cold-water swimming causes more heart attacks in summer than in winter

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

  D. Polar Bears are bears swimming in freezing water

The Polar Bears like to swim all the year round, for __________.

  A. they can remain young                         B. it is an easy way to keep the body warm in winter

  C. they find it enjoyable and interesting        D. they might meet fewer troubles in life

The passage is mainly about __________.

A. a group of cold-water swimming lovers              

B. the polar bears' life 

  C. doctors' ideas about cold-water swimming              

D. the requirements of the Polar Bear Club
