     According to sociologists(社会学家), every modern industrial society has some form of social stratification(阶层). Class, power and status are important in deciding people's rank in society.

     Class means a person's economic position in society. A commonly used classification is lower class, middle class and upper class. While sociologists disagree on how these terms should be exactly defined, they do describe societies like the United States quite well. One study shows that 53% of Americans belong to the lower class, 46% the middle class, and 1% the upper class. Interestingly, a surgeon earning $500,000 a year and a bus driver earning $50,000 a year both regard themselves as the middle class!

     Power refers to the amount of control a person has over other people. Obviously, people in positions of great power (such as governors) exercise(行使)big power, but people who take orders from others have less power. Power and class do not always go hand in hand, however. For example, the governor of a state has great power, but he or she may not belong to a corresponding (相应的)economic class. Generally, however, there is a relationship between power and class. To our knowledge, there aren't too many people who aren't millionaires in the U．S. Senate!

    Status is the honor or respect attached to a person's position in society. It can also be affected by power and class, but not necessarily so. For example, a university professor may have a high status but not belong to a high social class or have a lot of power over others.

1.What can we learn about “the middle class” from Paragraph 2?

A.People earning $50,000 a year belong to the middle class.

B.Nearly half Americans belong to the middle class.

C.People generally consider bus drivers as the middle class.

D.Sociologists have a clear definition of the middle class.

2.According to the text, we know that ________.

A.Power and class do not always correspond with each other

B.Status refers to a person's economic position in society

C.People with high status have a lot of control over others

D.Class is less important in deciding a person's social rank

3.Which of the following shows the structure of the whole text?

A. B.

C. D.

    If there is no difference in general intelligence between boys and girls, what can explain girls’ poor performance in science and mathematics?

It seems to be that their treatment at school is a direct cause. Mathematics and science are seen as subjects mainly for boys, and therefore, as girls become teenagers, they are less likely to take them. Interestingly, both boys and girls often regard the subjects for boys as more difficult. Yet it has been suggested that girls do not take mathematics courses, not because they are difficult, but for social reasons. Girls do not want to be in open competition with boys because they are afraid to appear less feminine and attractive.

However, if we examine the performance of boys and girls who have taken mathematics courses, there are still more high-achieving boys than there are girls. This difference appears to be world-wide. Biological explanations have been offered for this, but there are other explanations, too.

Perhaps the difference which comes out during the teenage years has its roots in much earlier experiences. From their first days in kindergarten, boys are encouraged to work on their own and to complete tasks. Facts show that outstanding mathematicians and scientists have not had teachers who supply answers.

Besides, there can be little doubt that teachers of mathematics and science expect their boy students to do better at these subjects than their girl students. They even appear to encourage the difference between boys and girls. They spend more time with the boy students, giving them more time to answer questions and working harder to get correct answers from them. They are more likely to call in boys for answers and to allow them to take the lead in classroom discussion. They also praise boys more frequently. All of this seems to encourage boys to work harder in science and mathematics and to give them confidence that they are able to succeed.

Such a way of teaching is not likely to encourage girls to take many mathematics and science courses, nor is it likely to support girls who do. When it comes to these subjects it seems certain that school widens the difference between boys and girls.

1.Girls are likely to think that _____.

A.science courses are for both boys and girls

B.science courses make them more popular

C.science courses make them successful

D.science courses are difficult for them

2.The text mainly discuss_____ reasons for the difference between boys and girls in scientific achievements.

A.biological B.historical

C.social D.personal

3.What are boys usually encouraged to do at school? _____

A.To get help with their homework. B.To play the leading role in class.

C.To work with girl students in class. D.To learn to take care of others.

4.The author would probably agree that ______.

A.boys and girls learn in the same way

B.boys and girls are equal in general intelligence

C.girls are more confident in themselves than before

D.girls should take fewer science courses than boys
