Healthy knees aren’t the main consideration in choosing high heels, but new research says chunky heels are just as bad for the knees as spindly stilettos（细高跟鞋）.“It takes a long time to feel the effects of knee osteoarthritis（骨关节炎）—and once you do it, it is too late,”said Dr.Casey Kerrigan, leading researcher of the study and associate professor at Harvard Medical School’s department of physical medicine.“I compare it to smoking—one cigarette is not painful, but over a lifetime it is. Wide-heeled shoes feel comfortable, so women wear them all day long,”Kerrigan said.“They are better for your feet than stiletto heels, but just as bad for your knees.”
In the study, researchers had twenty women wear two pairs of shoes with three-inch heels, one with a narrow heel and the other with a thick one. The scientists compared how much pressure was put on the women’s knees by both types of shoes. The women also walked bare-foot to test normal pressure. The scientists found that both types of shoes applied equal amounts of pressure to the knees. Compared with walking barefoot, the heels increased pressure on the inside of the knee by 26 percent. Increased pressure on the knee eventually leads to arthritis, experts say.
The idea that high heels are bad for your health isn’t new—scientists have warned women for years that they contribute to problems ranging from corns to hammer toes, tendonitis, knee pain, sprained（扭伤）ankles and back problems. But in 1998,Kerrigan and a team of Harvard researchers were the first to link high heels and knee osteoarthritis, a painful joint disease that destroys cartilage（软骨）surrounding the knee. The first study looked only at stiletto heels, and Kerrigan said she wanted to study the chunky high-heeled shoes she noticed many women wearing.“This study confirms what we all intuitively（直觉地）know that high-heeled shoes of any kind are not good for our health,” said Dr.Glem Pfeffer, a San Francisco doctor and member of the American Academy of Orthopaedic Surgeons who was not connected to the study.

I grew up in a small town. I was only ten years old when my dad gave me the responsibility of feeding the chickens and cleaning up the stable (马厩). He believed it was important for me to have those jobs to learn responsibility. Then, when I was 22, I found a job in Natchbill at a country music club called the Natchbill Palace. I washed dishes and cooked from 4:00 pm to 9:00 pm and then went on stage and sang until 2:00 in the morning. It wasn’t long before I became known as a singing cook. I had been rejected so many times by record companies that it was hard not to be discouraged.
One night, a woman executive (董事) from a company named Warner Brothers Records came to hear me sing. When the show was over, we sat down and talked and after she left, I said to myself it was one more rejection. A few weeks later, my manager received a phone call — Warner Brothers wanted to sign me to a record deal. Soon after, I had my first record in June 1986. It sold over 2 million copies. My best efforts had gone into every job I’ve ever held. It was the sense of responsibility that made me feel like a man.

What should I eat for breakfast? Who should I go out with on weekends? What should I do if I miss the bus to school? What colleges should I apply for? Again and again Chinese kids ask these questions to their teachers and parents. They can’t make their own choices.
Kids in America would be very surprised to hear how much Chinese children depend on adults. When they are ten years old, kids decide what clothes they want to wear and buy. By twelve they know what classes to take for middle school. Thirteen years old is the beginning of being what Americans call a “teenager”. Now the child is up to almost all his / her decisions. Finally at sixteen the kid usually gets a car from his / her parents.
Why should kids be independent? Think about it. After high school most of us will be by ourselves. Will our parents be able to tell us what to eat for breakfast in college? Can our teachers decide what we should do at work?
Making our own choices can be quite hard and scary. But we can start with making small choices, and then slowly make bigger and more important choices.
64. The first paragraph is written to tell the readers that Chinese kids ______.
A. don’t know what to do B. always have many questions
C. believe in their teachers and parents D. depend on adults too much

B. American kids will more easily adapt themselves to society.
C. American parents don’t care for their children.
D. A sixteen American youngster can drive his / her own car.

Today, robots come in all shapes and sizes. They can’t complain, even if the work is heavy and dangerous. And they can work or play all day without getting bored. Unlike a human’s arms, a robot’s joints will never get stiff (僵硬的). The end of the arm can be fitted with devices (装置) to perform different tasks. These could be a welding (焊接) point, suction cups (吸附杯) or gripping fingers (钳形指) for lifting and moving objects. Such an arm of these computer controlled industrial robots can work 24 hours a day.
Robopets (机器人宠物) are high-tech robots programmed to play. They can communicate with their owners and recognize their voices. Each one will develop a different “personality”. They can be a lot of fun to play with, but these robots can also be helpful to people who are sick and can’t look after a real animal. Many doctors believe that when a person is happy and laughing, their body recovers faster. A robopet might be just what the doctor ordered.
NeCoRo is a robot cat that has been developed to be more than a toy. The robot uses sensors (传感器) that can detect movement and sound. It can even store helpful information in its memory. Its behaviour changes over time, just like a real pet.
60. From Paragraph 1 we learn that ________.
A. a human’s arms never get stiff
B. robots sometimes get bored just as humans do

D. NeCoRo’s behaviour changes over time.
63. What does the underlined word “detect” in Paragraph 3 mean?
A. Recognize. B. Create. C. Store. D. Destroy.

Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings. It is caused mainly by industrial underwater explosions, ocean drilling, and ship engines.
Some scientists have proposed setting a noise limit of one hundred and twenty decibels (分贝) in oceans. They have observed that noises at the level can frighten and confuse (使困惑) whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals. They found that powerful underwater explosions were causing whales in the area to lose their hearing. This seriously affected the whales’ ability to exchange information and find their way. Some of the whales even died.
Some researchers whose work depends on ocean sounds object to (反对) a limit of one hundred and twenty decibels. They say such a limit would mean an end to important industrial and scientific research. Scientists do not know how much and what kinds of noises are harmful to ocean animals. However, many scientists agree that noise is a greater danger than they believed. They want to prevent noises from harming creatures (生物) in the ocean.
56. According to the passage, which of the following is increasingly dangerous to sea creatures?
A. The man-made noises.
B. The noises made by themselves.
C. The sound of earthquakes.
D. The sound of ice-breaking.
57. Concerning the effect of noises on whales, which of the following is TRUE?
A. They are deaf to noises.
B. Noises at a certain level may hurt them.
C. Noises could kill them.
D. Noises will cause them to lose their eyesight.
58. Some scientists think that the noise limit of one hundred and twenty decibels would _________.
A. prevent them doing their research work
B. benefit them a lot in their research work
C. do good to their health
D. increase the industrial output
59. According to the last paragraph, what will scientists most probably do in the future?
A. They will study the effect of different noises in the sea.
B. They will work hard to make no noise.
C. They will never do any scientific research in the sea.
D. They will protect sea animals from harmful noises.
