An Australian professor is developing a robot to monitor the health of grazing cattle, a development that could bring big changes to a profession that's relied largely on a low-tech approach for decades but is facing a labor shortage.
Salah Sukkarieh, a professor at the University of Sydney, sees robots as necessary given how cattlemen are aging. He is building a four-wheeled robot that will run on solar and electric power. It will use cameras and sensors to monitor the animals. A computer system will analyze the video to determine whether a cow is sick. Radio tags （标签）on the animals will measure temperature changes. The quality of grassland will be tracked by monitoring the shape，color and texture （质地） of grass. That way， cattlemen will know whether they need to move their cattle to another field for nutrition purposes.
Machines have largely taken over planting, watering and harvesting crops such as com and wheat, but the monitoring of cattle has gone through fewer changes.
For Texas cattleman Pete Bonds, it's increasingly difficult to find workers interested in watching cattle. But Bonds doesn't believe a robot is right for the job. Years of experience in the industry - and failed attempts to use technology - have convinced him that the best way to check cattle is with a man on a horse. Bonds, who bought his first cattle almost 50 years ago, still has each of his cowboys inspect 300 or 400 cattle daily and look for signs that an animal is getting sick.
Other cattlemen see more promise in robots. Michael Kelsey Paris, vice president of the Oklahoma Cattlemen's Association, said a robot could be extremely useful given rising concems about cattle theft. Cattle tend to be kept in remote places and their value has risen, making them appealing targets.

There is an English saying:“ laughter is the best medicine.” Until recently, few people took the saying seriously. Now, however, doctors have begun to look into laughter and the effects it has on the human body. They have found that laughter really can improve people’s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while doctors checked their hearts, blood pressure, breathing and muscles. It was found that laughter had similar effects to physical exercise. It increases blood pressure, the heart beating and breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial .
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group that tolerated(忍耐)the pain for the longest time was the groups which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemicals in the brain which diminish both stress and pain .
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they help to improve their patients’ condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

.The main idea of the passage is .
| A．laughter and physical exercise have similar effects on the human body |
| B．smile can produce the same effects as laughter |

The students who ___ tolerated the pain for the longest time .

Jenny was almost five. Waiting with her mother at the checkout stand, she saw a circle of white pearls（珍珠） in a box. “Oh please, Mommy .Can I have them? Please, mommy, please!”
Quickly the mother checked the back of the little box and said ,” That’s almost $2.00. If you really like them, I’ll think of some extra chores for you and in no time you can save enough money to buy them for yourself.”

Here is an unusual story: a diamond ring was recently found in an egg. The magician, Liu Qian, discovered it, in front of an audience of millions at CCTV`s Spring Festival Gala.

Until a relatively short time ago, traveling abroad was limited to rich tourists and wealthy businesspeople. Flying abroad was not common for the average person. In time, however, plane travel became safer, more convenient, and less expensive. As a result, people of different backgrounds now fly to distant places for pleasure and businesspeople fly to one country for a breakfast or lunch conference, and then fly to another country for a dinner meeting.
With the world becoming smaller, many young adults make the decision to study in foreign universities. It is an exciting, challenging experience to live in a foreign country. Anyone who can study abroad is fortunate; but, of course, it is not easy to change from one culture to another. One faces many difficulties.
The student who studies in a foreign country leaves behind a familiar, loving, comfortable environment. Back home, he has his family, friends, and acquaintances. He knows the language, politics, money, food, social customs, and so forth. He knows all the unclear aspects of his native culture, such as body language, and bargaining practices, etc. in short, he knows “the system” in his native country. Then one day he leaves all this behind and suddenly finds himself in a place where everyone and everything is strange, perhaps even confusing. All this strangeness is a major surprise to a person’s self-confidence. This sudden change often leads to a reaction called culture shock.
Foreigners experience different degrees of culture shock. The symptoms range from being ill at ease to being seriously depressed. Feeling homesick, unhappy, and very sensitive are other signs of culture shock. It is easy to understand that the endless frustrations of the early days in a new country would produce dissatisfaction, and perhaps even hostility. People are always at ease in a familiar environment. A mature, realistic person experiences mild, temporary symptoms; the insecure newcomer suffers more seriously from a culture shock.
During the inevitable period of adjustment, the international student tends to complain about everything in the new environment. In fact, the student is likely to exaggerate the problems. When the student meets another miserable person from the same country, he will pour out his unhappy feelings. Together they can complain in their native language. Although this complaining provides temporary satisfaction, it certainly does not help him adapt to a new society. Being negative will never get rid of the feelings of frustrations. The mature person understands that a positive attitude, determination, and flexibility are important in making the change successful. A sense of humor is a big help.
