　　Many people will remember the flight of the space shuttle（航天飞机）challenger，in June，1983. The achievement of Sally Ride，America’s first woman astronaut to fly into space，made this flight especially memorable. Students from two Camden, New Jersey, high schools, however, are probably to remember Norma rather than Sally whenever they think about the flight.
　　Norma didn’t travel alone. She brought about 100 companions along with her. Norma was an ant，a queen ant who，with her subject，made up the first ant colony（群体）to travel into space. The ants were part of a science experiment designed by students to test the effects of weightlessness on insects.
　　The equipment designed by the students for their colony functioned perfectly throughout the long space trip. The young scientists and their teachers were very sad to find that their insect astronauts had all died at some point before the container was returned to the school and opened. The problem didn’t occur in space，but on the ground after challenger had landed. The container remained in the desert for nearly a week before the ant colony was moved. The hot，dry desert air dried out the colony’s container and the ants died from lack of moisture（水分）.
　　The project was termed success because it did provide useful information. Students will continue their efforts to pinpoint（精确找到）what went wrong. They will try to prevent the same difficulties from reoccurring on future missions. They don’t want to be discouraged either by the demise of the ants or by the $ 10,000 shuttle fare they will have to pay to send the next colony of ants into space.
51．What does the passage mainly tell us？
A．Sally Ride，America’s first woman astronaut.

53．We don’t think the project was a failure. This is because_____.
A．everything went as smoothly as expected
B．the students had pinpointed exactly the reason
C．something important had been learned
D．the students had succeeded in the experiment
54．We can conclude that ants _____ on the next space trip.
A．will have to be kept alive in a container full of water
B．will have to be sent into space with the first woman astronaut
C．should be put into a container where there is enough food
D．should be put into a container which is not too dry

Having a husband means an extra seven hours of housework each week for women, according to a new study. For men, getting married saves an hour of housework a week. “It’s a well-known pattern,” said lead researcher Frank Stafford at University of Michigan’s Institute for Social Research. “Men usually work more outside the home, while women take on more of the housework.”

　　He points out that differences among households(家庭)exist. But in general, marriage means more housework for women and less for men. “And the situation gets worse for women when they have children,” Stafford said.

　　Overall, times are changing in the American home. In 1976, women busied themselves with 26 weekly hours of sweeping-and-dusting work, compared with 17 hours in 2005. Men are taking on more housework, more than doubling their housework hours from six in 1976 to 13 in 2005.

　　Single women in their 20s and 30s did the least housework, about 12 weekly hours, while married women in their 60s and 70s did the most-about 21 hours a week.

　　Men showed a somewhat different pattern, with older men picking up the broom more often than younger men. Single men worked the hardest around the house, more than that of all other age groups of married men.

　　Having children increases housework even further. With more than three children, for example, wives took on more of the extra work, clocking about 28 hours a week compared with husbands’10 hours.

1. According to the “well-known pattern” in Paragraph 1, a married man___________.

A．takes on heavier work                    B．does more housework

C．is the main breadwinner                  D．is the master of the house

2. How many hours of housework did men do every week in the 1970s?

A．About 23.         B．About 26.          C．About 13.         D．About 6.

3. What kind of man is doing most housework according to the text?

A．An unmarried man.                      B．An older married man.

C．A younger married man.                  D．A married man with children.

4. What can we conclude from Stafford’s research?

A．Marriage gives men more freedom.

B．Marriage has effects on job choices.

C．Housework sharing changes over time.

D．Having children means doubled housework.

Can you communicate with others when you live in a foreign country with no or little knowledge of its language? Of course, it is possible. You can communicate your moods and intentions to one another without words, because all human beings share a lot of common visual（看见的）signals. These signals are as effective as words during communication.

The gestures of the head play a key role in body language. The movements of eyes and eyebrows are as important as head movements in body language.

　　Besides the gestures of the head or the movements of the eyes and eyebrows, the action of arms, hands and legs is also a large part of body language. Extending one's arm and shaking hands with others is a greeting in both formal and informal cases. This part of body language might date back to primary tribes（部落）.

　　Like handshaking, there are still many other forms of body language presented by hands. Raising one's hand and making a circle with his thumb（拇指）and for finger signals, that something is OK. Clasped（握紧的）hands raised above the head, a traditional picture accepted by sportsmen after winning a fight, is a display of triumph that grows out of a kind of feeling following a victory. Waving one's hands, a speaker can make his words more powerful and vigorous（有活力的）.

　　Besides hand gestures, there are times when a person says something with his legs as well as with his head and eyes. The leg gestures often reflect one's attitude towards something or someone that person is with.

　　According to the above facts, body language has offered a more reliable（可靠的）way to understand one's mind by means of gestures. Though it is soundless and wordless, once you understand it, you will feel the world is bigger than you realized.

1. Which of the following is the proper title for this passage?

2.After reading the passage we can conclude that ________.

3.What's the characteristic of body language?

4.When sports men win a match, they probably ________.
