There are people in Italy who can’t stand soccer. Not all Canadians love hockey. A similar situation exists in America, where there are those individuals you may be one of them who frown when somebody mentions baseball. Baseball to them means boring hours watching grown men in funny tight outfits standing around in a field staring away while very little of anything happens. They tell you it’s a game better suited to the 19th century, slow, quiet, and gentlemanly. These are the same people you may be one of them who love football because there’s the sport that values “the hit”.

By contrast, baseball seems abstract, cool, silent, still.

On TV the game is divided into a dozen perspectives, replays, close-ups. The geometry(幾何學(xué)) of the game, however, is essential to understanding it. You will view the game from one point as a painter does his subject; you may, of course, project yourself into the game. It is in this projection that the game affords so much space and time for involvement. The TV won’t do it for you.

Take, for example, the third baseman. You sit behind the third base and you watch him watching home plate. His legs are apart, knees flexed(彎曲). His arms hang loose. He does a lot of this. The skeptic(懷疑論者) still cannot think of any other sports so still, so passive. But watch what happens every time the pitcher throws: the third baseman goes up on his toes, flexes his arms or brings the glove to a point in front of him, takes a step right or left, backward or forward, perhaps he glances across the field to check his first baseman’s position. Suppose the pitch is a ball. “Nothing happened,” you say. “I could have had my eyes closed.”

The skeptic and the innocent must play the game. And this involvement in the stands is no more intellectual than listening to music is. Watch the third baseman. Smooth the dirt in front of you with one foot; smooth the pocket in your glove; watch the eyes of the batter, the speed of the bat, the sound of ball on wood. If football is a symphony of movement and theatre, baseball is chamber music, a spacious interlocking(連鎖) of notes, chorus(和聲)and responses.

1.The passage is mainly concerned with .

A. the attraction of baseball

B. the superiority of football

C. the different tastes of people for sports

D. the different characteristics of sports

2.Those who don’t like baseball may complain that .

A. it is only to the taste of the old

B. it is not exciting enough

C. it involves fewer players than football

D. it is pretentious and looks funny

3.The author admits that .

A. baseball may seem boring when watched on TV

B. football is more attracting than baseball

C. baseball is more interesting than football

D. baseball is too peaceful for the young

4.By stating “I could have had my eyes closed”, the author means (4th paragraph last sentence) .

A. The consequence was so bad that he could not bear to see it

B. The third baseman is so good at baseball that he could finish the game with eyes closed all the time and do his work well

C. Even if the third baseman closed his eyes a moment ago, it could make no difference to the result

D. The third baseman would rather sleep than play the game

People born in winter are more likely to suffer mental health disorders, according to a recent study carried out by researchers at Vanderbilt University in Tennessee.

Researchers raised baby mice from birth to weaning (斷奶) in either “summer” light cycles of 16 hours of light and 8 hours of dark or “winter” cycles of 8 hours of light and 16 hours of dark. A third group experienced 12 hours of light and 12 hours of dark a day.

Then half the winter mice stayed in a winter cycle, while half switched to a summer schedule. The summer mice were similarly split. The mice raised in equal periods of light and dark were split into three groups, one of which stayed on the 12?hour schedule, one of which joined the winter group, and one of which joined the summer group.

After 28 days, it turns out the summer?born mice behaved the same whether they stayed on the summer cycle or switched to winter. But among the winter?born mice, those stayed in winter kept their previous schedule, while those that switched to summer stayed active for an extra hour and a half, which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks.

The finding is the first of its kind in mammals, and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression, schizophrenia and seasonal affective disorder.

“We know that the biological clock regulates mood in humans”said study researcher McMahon. “If the mechanism (機(jī)制) similar to the one that we found in mice operates in humans, then it could not only have an effect on a number of behavioral disorders, but also have a more general effect on personality.”

1.How many groups of mice are there finally in all in the experiment?

A. Four.B. Five.C. Six. D. Seven.

2.What's the main idea of the text?

A. The biological clock regulates mood in humans.

B. People born in winter are at higher risk for physical health disorders.

C. Being born in winter has a negative effect on people's mental health.

D. The length of light will influence the behavior of the mice.

3.The underlined word “split”(Paragraph 3) can be replaced by ________.

A. endedB. torn C. hitD. divided

4.Who is the appropriate reader of the passage?

A. A job?hunter. B. A student in the university.

C. A newly?married couple. D. An experienced dentist.
