“All men are created equal” is one idea that nearly every American would agree upon.  36 they sometimes betray the idea in their daily lives, they have a deep faith  37 in some fundamental way no one is born superior to anyone else.
In the early years of American history, because titles of nobility(贵族) were forbidden, no  38 class system developed in the United States. Firmly believing that being born into a lower class would not  39 them from success and they would have a better chance in America, thousands of immigrants   40 to leave the European societies, where their    41  in life was determined  42 by the social class into which they were born. It was because the dreams of many of there immigrants were   43 in their new country, though there might be  44 in some situations, that Americans came to believe in equality of opportunity.
Americans do not mean that everyone should be  45 equal when they say they believe in equality of opportunity.  46 , they do mean that each person should have an equal chance for success. Abraham Lincoln once said, “We wish to  47 the humblest(最微贱的) man an equal chance to get rich with everybody else. When one starts poor, free society is  48 that he knows he can   49 his condition.”
However, competition is the price to be   50  for his equality of opportunity.

People born in the 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（断奶） in either “summer” light cycles of 16 hours of light and eight hours of dark or “winter” cycles of eight 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 subset.

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 the 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 an imprinting mechanism（运行机制）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.”

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

A. four　　　　 　　　　 B. five　　　　　 　　　 C. six　　　　　 　　 D. seven

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

　　 A. The biological clock regulates mood in humans.

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

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

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

45. The underlined word "split" can be replaced by 　　　　 ? （Line 2, Paragraph3）

　　 A. divided　 　　　　　　　 B. torn　 　　　　　　　　 C. hit　　 D. ended

46. Which group of mice has changed their behavior after the experiment?

　　 A. The group born in the winter and staying in the winter.

B. The group born in the winter and switching to the summer.

　　 C. The group born in the summer and staying in the summer.

D. The group born in the summer and switching to the winter.

47. 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
