The twentieth century saw greater changes than any century before: changes for the better, changes for the worse; changes that brought a lot of benefits to human beings, changes that put man in danger. Many things caused the changes, but, in my opinion, the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe; it has brought us a better understanding of the nature of life and of its continuous development. Technology—the application of science—has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science — a wider and deeper knowledge in all fields of learning; in applied science — a more reasonable sharing of material benefits, and better protection of the environment.
Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although
their actual use has so far occurred only the Second World War, the number of nuclear weapons that were produced and made ready for us was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
William Shakespeare said, “The web of our life is of a mingled yarn(沙线), good and ill together.” The above brief review of the application of only one part of human activities — science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?

In the US and Britain, the slogan around colleges was “Save water. Shower with a friend.” Now, Wuhan University has come up with another system for the campus bathhouse. It charges students for the amount of time in a shower. Before entering the bathhouse, students pay for the amount of time they want in the shower with cash or their student ID card. The clock starts ticking the minute the tape is turned on. It pauses when a button is pressed for soap. An integrated circuit (IC) card reader at each tap shows the time. No money, no water. The benefits of the new system can be seen with the old system, which charged 1 Yuan for each person regardless of time in the shower. The university used about 320 tons of water daily under the old system, but only 160 tons now.
Many students use the new system but opinions on it are divided. Some students say it is bad because bathing had become a sort of race. Many people using it for the first time are not sure how long they need to shower. Some might be embarrassed if their time is up and they’re still covered in soap. They have to ask the bathhouse worker to help them buy extra time.
“It’s a flaw in the system that you can not buy extra time on the ID card,” said Ren, a freshman in Wuhan University. The university is also considering some students’ suggestions that they be allowed to pay after they’ve finished the shower. Not surprisingly, some are complaining about losing the hour shower. But many students say the move helps them develop a water-saving sense.
Without the time limits, most students tended to shower for 30 to an hour in the bathhouse.
Some even used the hot water to wash their clothes. “In my experience, 10—20 minutes is enough,” said Dai Zhihua, a third-year student who usually takes 8 minutes.
A similar system has been installed in other universities. Shanghai Normal University introduced it at its Fengxiang Campus in September. The bathing fee there is 0.2 Yuan per minute. One male student responded by setting a record with a two-minute shower.According to the passage, which of the following is NOT true?
| A．Students pay for the amount of time they want in the shower. |
| B．The clock times all through while the student is bathing except when the bather paused for soap. |
| C．If money runs out, there will be no water. |
| D．Having finished bathing, the student has to pay for it. |
The underline word “flaw” (Paragraph 3) most probably means __________.
| A．fault | B．advantage | C．pity | D．perfection |
Since the new system has performed, __________ of water can be saved.
| A．a quarter | B．one third | C．one half | D．two thirds |
It can be inferred from the passage that __________.
| A．The new operation can raise students’ environmental awareness. |
| B．the new operation can solve the water crisis. |
| C．a similar operation has been set in other universities. |
| D．The university has saved a lot of water by using the new system. |
In which column can you find this passage?

Five years ago, David Smith wore an expensive suit to work every day. “I was a clothes addict,” he jokes. “I used to carry a fresh suit to work with me so I could change if my clothes got wrinkled.” Today David wears casual clothes—khaki pants and sports shirt—to the office. He hardly ever wears a necktie. “I’m working harder than ever,” David says, “and I need to feel comfortable.”
More and more companies are allowing their office workers to wear casual clothes to work. In the United States, the change from formal to casual office wear has been gradual. In the early 1990s, many companies allowed their employees to wear casual clothes on Friday, but only on Friday. This became known as “dress-down Friday” or “casual Friday”. “What started out as an extra one-day-a-week benefit for employees has really become an everyday thing.” said business consultant Maisly Jones.
Why have so many companies started allowing their employees to wear casual clothes? One reason is that it’s easier for a company to attract new employees if it has a casual dress code. “A lot of young people don’t want to dress up for work,” says the owner of a software company, “so it’s hard to hire people if you have a conservative dress code.” Another reason is that people seem happier and more productive when they are wearing comfortable clothes. In a study conducted by Levi Strauss Company, 85 percent of employers said that they believe that casual dress improves employee morale（士气）. Only 4 percent of employers said that casual dress has a negative effect on productivity. Supporters of casual office wear also argue that a casual dress code helps them save money. “Suits are expensive, if you have to wear one every day,” one person said. “For the same amount of money, you can buy a lot more casual clothes.” David Smith refers to himself as having been “a clothes addict,” because__________.
| A．he often wore khaki pants and a sports shirt |
| B．he couldn’t stand a clean appearance |
| C．he wanted his clothes to look neat all the time |
| D．he didn’t want to spend much money on clothes |
David Smith wears casual clothes now, because__________.
| A．they make him feel at ease when working |
| B．he cannot afford to buy expensive clothes |
| C．he looks handsome in casual clothes |
| D．he no longer works for any company |
According to this passage, which of the following statements is FALSE?
| A．Many employees don’t like a conservative dress code. |
| B．Comfortable clothes make employees more productive. |
| C．A casual clothes code is welcomed by young employees. |
| D．All the employers in the U.S. are for casual office wear. |
According to this passage, which of the following statements is TRUE?
| A．Company workers started to dress down about twenty years ago. |
| B．Dress-down has become an everyday phenomenon since the early 1990s. |
| C．“Dress-down Friday” was first given as a favor from employers. |
| D．Many workers want to wear casual clothes to impress people. |
In this passage, the following advantages of casual office wear are mentioned except
__________.
| A．saving employees’ money | B．making employees more attractive |
| C．improving employees’ motivation | D．making employees happier |
Anger is good for you, as long as you control it, according to new psychology research. A new study from Carnegie Mellon University shows anger may help people reduce the negative impacts of stress and help you become healthier.
“Here getting emotional is not bad for you if you look at the case of anger,” said Jennifer Lerner of Carnegie Mellon. “The more people display anger, the lower their stress responses.”
Lerner studied 92 UCLA students by asking them to count back from 6,200. They must say out loud every thirteenth number. Researchers disturbed them by asking them to count faster or ask them other questions. If they made any mistakes, they had to restart from the very beginning. Many students felt depressed about making so many mistakes or got angry.
Lerner used a hidden video camera and recorded all their facial expressions during the test. The researchers describe their reactions as fear, anger and disgust.
Other researchers recorded the students’ blood pressure, pulse and production of a high-stress hormone（荷尔蒙）called cortisol. People whose faces showed more fear during the experiment had higher blood pressure and higher levels of the hormone. Both can have lasting effects such as diabetes（糖尿病）, heart disease, depression and extra weight gain.
When people feel fear, negative impacts increase, but when they get angry, those negatives go down, according to the study.
“Having that sense of anger leads people to actually feel some power in what otherwise is a maddening（令人发狂的）situation,” Lerner said.
Lerner previously studied Americans’ emotional response to the 9/11 terrorist attacks two months after the incident. She found people who reacted with anger were more optimistic. These people are healthier compared with those who were frightened during the event. So in maddening situations, anger is not a bad thing to have. It’s a healthier response than fear. What is the story mainly about?
| A．The findings of new psychology research. |
| B．What you can do with anger in certain cases. |
| C．Different effects produced by anger and fear. |
| D．Healthier responses in maddening situations. |
Which statement will Jennifer Lerner agree with?
| A．It’s better to be angry than to be frightened. |
| B．Different reactions reflect different outlooks on life. |
| C．Don’t control your anger and it makes you powerful. |
| D．Pessimistic people are generally healthier than optimistic people. |
What does the underlined word “both” refer to according to the passage?
| A．Fear and anger. | B．Blood pressure and pulse. |
| C．Blood pressure and cortiso1. | |
| D．Higher blood pressure and higher levels of the hormone. |
In what ways can anger be beneficial to people?
| A．By showing their optimistic side. | B．By reducing their stress. |
| C．By reducing high blood pressure. | D．By taking the place of fear. |
The researchers irritated（激怒）the students by __________.
| A．recording their performance secretly |
| B．asking them to count to 6, 200 again and again |
| C．disturbing them and making them start all over again |
| D．criticizing them when they made mistakes |
Everybody has one of those days when everything goes wrong. This is what happened to Harry.
He got up one morning very late because he had forgotten to wind up his alarm clock（闹钟）. He tried to shave（刮脸）quickly and cut himself. When he got dressed he got blood all over his clean shirt, so he had to find another one. The only other shirt that was clean needed ironing（熨）, so he ironed it. While he was ironing it, there was a knock at the door. It was the man to read the electricity meter（表）. He showed him where the meter was, said good-bye and found that the iron had burnt a hole in his shirt. So he had to wear the one with the blood on it after all. By this time it was very late, so he decided he couldn’t go to work by bus. He telephoned for a taxi to take him to work. The taxi arrived and Harry got in and began to read the newspaper.

The teacher who did the most to encourage me was, as it happened, my aunt. She was Myrtle C. Manigault, the wife of my mother’s brother Bill. She taught in second grade at all-black Summer School in Camden, New Jersey.
During my childhood and youth, Aunt Myrtle encouraged me to develop every aspect of my potential, without regard for what was considered practical or possible for black females. I liked to sing; she listened to my voice and pronounced it good. I couldn’t dance; she taught me the basic dancing steps. She took me to the theatre ---- not just children’s theatre but adult comedies and dramas—and her faith that I could appreciate adult plays was not disappointed.
My aunt also took down books from her extensive library and shared 
them with me. I had books at home, but they were all serious classics. Even as a child I had a strong liking for humor, and I’ll never forget the joy of discovering Don Marquis’s Archy & Mehitabel through her.
Most important, perhaps, Aunt Myrtle provided my first opportunity to write for publication. A writer herself for one of the black newspapers, she suggested my name to the editor as a “youth columnist”. My column, begun when I was fourteen, was supposed to cover teenage social activities—and it did—but it also gave me the freedom to write on many other subjects as well as the habit of gathering material, the discipline of meeting deadlines, and, after graduation from college six years later, a solid collection of published material that carried my name and was my passport to a series of writing jobs.
Today Aunt Myrtle is still an enthusiastic supporter of her “favourite niece”. Like a diamond, she has reflected a bright, multifaceted (多面的) image of possibilities to every pupil w
ho has crossed her path.Which of the following did Aunt Myrtle do to the author during her childhood and youth?
| A．She lent her some serious classics. | B．She cultivated her taste for music. |
| C．She discovered her talent for dancing. | D．She introduced her to adult plays. |
Aunt Myrtle recommended the author to a newspaper editor mainly to ______.
| A．involve her in teenage social activities | B．give her a chance to collect material |
| C．develop her capabilities for writing | D．offer her a series of writing jobs |
We can conclude from the passage that Aunt Myrtle was a teacher who ______.
| A．gave pupils confidence in exploiting their potential |
| B．trained pupils to be diligent and well-disciplined |
| C．emphasized what was practical or possible for pupils. |
| D．helped pupils overcome difficulties in learning |
