     By analyzing academic data from 10 states,representing the testing of more than 7.2 millions of youths,US researchers found that gender differences in math scores were extremely small among all ethnic
groups in grades 211.
     These findings are in contrast to earlier results from 1990 that indicate measurable differences favoring males in complex problemsolving,beginning in the high school years.
    Janet Hyde from University of Wisconsin and colleagues reported their study results in the journal
Science on Friday.
      Currently,women are largely absent from the highest levels of careers in mathematics,the physical
sciences,and engineering.In the United States,Ph.D.programs in engineering currently average only about
15 percent women,and similar statistics have led to stereotypes (成見) about girls and women lacking in
mathematical ability.
     Now,it is clear that the general population no longer shows a gender difference in mathematical skills,
according to this latest report.
     And this new data on academic performance in the United States shows that students are tested frequently on "recall" and "skill/concept" items,but rarely on "strategic thinking" (戰(zhàn)略思維) or "extended thinking" concepts.
If standardized tests do not assess the sorts of reasoning that are crucial to careers in science and math,
the skills may not be taught,putting American students at a disadvantage to students in other countries
where testing and instruction focuses on more challenging content."This is a gap that should be fixed,"
Hyde said.

1. What is the best title of the passage?

A. A new study result about math.
B. No gender differences in math.
C. Girls are not good at math.
D. Girls do better in math than boys.

2. Earlier research results________.

A. are the same as that of this latest report
B. support gender differences in math
C. indicate girls prefer to solve complex problems
D. are the roots of many stereotypes about women

3. The underlined word "crucial" in the last paragraph most probably means________.

A. limited  
B. available  
C. important  
D. equal

4. What Hyde said in the last paragraph means that________.

A. standardized tests should assess different classes around the world
B. testing and instruction should focus on more challenging content in the USA
C. students in other countries are cleverer than American students
D. students should be tested frequently on "recall" and "skill/concept" items

5. The passage is most probably taken from________.

A. a learning guide  
B. a research paper
C. a personal diary  
D. a newspaper

  Americans are always in a hurry, they seem to be under permanent pressure to think that there is something more to do the next moment. This fast pace is reflected in the popularity of fast-food restaurants, one-stop stations and micro-ovens. They hate to waste their time and would frown if their time is wasted by interruptions or by poor service. They appreciate the practice of doing things as quickly as possible, as in their eyes,“patience is the virtue of asses.”

  In contract, people in Indonesia believe in“rubber time”, to the extent that time can stretch or shrink. In Africa, people who do something in a rush are actually asking for trouble; they'd be suspected of trying to cheat! In their culture, a slow unusual, worth doubt.

  Here is a contract between the slow pace people (SPP) and the fast pace people(FPP);

  ◇SPP-Consider an appointment as a target to achieve, if possible.

   FPP-take a promise seriously and try to keep it by all means.

  ◇SPP-are dedicated to people and human relationship.

   FPP-are devoted to work rather than to human relationship.

   SPP-change plans easily.

   FPP-follow and stick to the plans.

  ◇SPP-decide to be punctual or not based on human relationship.

   FPP-stress punctuality.

  ◇SPP-show strong tendency to build lifetime friendship.

   FPP-are used to short-term relationship.

(1)Which of the following statements indicates that Americans are leading a fast-pace life?

[  ]

A.Americans have modern kitchen equipment.

B.Fast-food restaurants are popular with Americans.

C.Almost every American family owns a car.

D.There are a lot of railway stations in the United States.

(2)The underlined phrase“one-stop stations”probably means ________.

[  ]

A.A bus stop is not far from one another

B.There are a number of police stations in the United States

C.There are a lot of gas stations here and there, and it is one-stop distance between them.

D.It is a long way from a gas station to the next one

(3)In which country people who do something in a rush are suspected of trying to cheat?

[  ]

A.Venezuela      B.Italy

C.Vietnam       D.Zambia

(4)If a person cares more for human relationship than his job, he must belong to ________.

[  ]

A.the fast pace people

B.the slow pace people

C.the lazy people

D.the clever people

  By the early 19th century the factory system had spread to the U.S. The first cotton factory was built in 1814, and by 1850 some 24 percent of workers were women. They produced clothing, shoes, cigars, and other things. In the Northeast, newly-arrived women with little education became the factory force. In the South, black women moved into factory and domestic(家庭的)jobs, first as slaves and later as free workers.

  By 1890 nearly 4 million women in the U.S. worked for pay. This represented(代表)18 percent of the female population aged 14 and 17 percent of the total work force. Half the female workers were under 25 years of age, and seven out of ten were single. Most of them worked in domestic service, teaching positions, and textile(紡織的)factories; only about 5 percent were secretaries, clerks, or salespersons.

  Recent years have seen a rapid increase in the number of women joining the paid labour force in the U.S. Today, almost 54 percent of all women of working age are employed. Over 50 percent of working women are married, and 60 percent of working wives have school--aged children.

(1)By 1850 about _______ percent of workers were men.

[  ]

A.24
B.50
C.76
D.54

(2)By 1890 ________ of working women were married.

閱讀理解
     By now, a rocket will have set off on its 35-million-mile trip to Mars and scientists must be waiting for
the results.
     The rocket will be travelling for six months before it reaches the planet. It contains a number of
scientific instruments, including a television camera. Any picture that is taken will have to travel for three
minutes before they reach the earth. If the pictures are successful, they may solve a number of problems
about Mars and provide information about the markings on its surface which, nearly 100 years ago, the
astronomer (天文學(xué)家), Schiaparelli, thought to be canals.
     It will be a long time before any landing on Mars can be tried. This will only be possible when scientists have learned a lot more about the atmosphere that surrounds the planet. If a satellite can one day be put
into orbit round Mars, scientists will be able to find out a great deal. An interesting suggestion for
measuring the atmosphere around Mars has been made. A rubber ball having a radio transmitter(無(wú)線電發(fā)報(bào)機(jī)) could be dropped from a satellite so that it would fall towards the surface of the planet. The radio would tell the rate(速度) at which the ball was slowed down and scientists would be able to calculate how dense the atmosphere is. It may even be possible to drop scientific instruments on to the planet's surface. Only when a great deal more information has been got, will it be possible to plan a manned (載人的) trip
to Mars.
1. The first paragraph tells us _______ .
A. Mars is too far away for people to land on
B. it will take the rocket half a year to reach Mars
C. Mars is 53 million miles away from the earth
D. scientists have well known about the surface of Mars
2. The pictures taken by a television camera _______ .
A. will have to be put into the scientific instruments
B. will prove what Schiaparelli thought about is false
C. will be received by the earth in three minutes' time
D. can help people do much less research work
3. It seems that _______ might prevent scientists from landing on Mars.
A. the atmosphere round the planet
B. the orbit round the planet
C. having little information
D. the markings on the planet's surface
4. Having successfully dropped the rubber ball, scientists would be able to calculate how dense the atmosphere is by _______.
A. slowing the ball down at a speed which could be measured
B. dropping another ball with scientific instruments on to the surface
C. putting down the ball towards the planet's surface
D. measuring the speed at which the ball was falling
5. It is not until _______ that people can think of a plan to make a trip to Mars.
A. they have got enough scientific instruments
B. they have a lot more information
C. dense enough atmosphere is found around the planet
D. a reasonable suggestion has been made
