Too Late to Regret it When I was a junior, I met a second-year student in my department. He wasn't tall or good-looking, but he was very nice, attractive and athletic. He had something that I admired very much. He was natural, warm, and sincere.
I disregarded (不顾) my parents' disapproval. We were very happy together. He picked me up from my dorm every morning, and after class we would sit alongside the stream that ran through campus, or sunbathe (晒太阳) on the lawn. At night he would walk me back to my dorm. He came from a poor family, but in order to make me happy, he borrowed money from his friend to buy presents and meals for me. Our fellow students looked up to him as a role model, and the girls envied (妒忌) me. He wasn't a local, but wanted to stay here after graduation. I thought we had a future together.
However, when I got a part-time job during the summer vacation, people began giving me a lot of pressure, saying that a pretty, intelligent girl like me should find a better guy to spend time with. This was also what my family thought. He spent the summer in his hometown, so I was all by myself. When he got back, I began finding fault with him. But his big heart and warmth soon drove all unpleasant thoughts away. However, I had no idea how badly I had hurt him and that things would get worse.
I had a good part4ime job off campus that paid pretty well. With my good performance at school, I also got admission to graduate school at one of China's best universities. He, on the other hand, did not do so well at school or at work. I had to worry about his living expenses, job and scores.
Almost all my colleagues and friends advised me to break up with him. Then we had a quarrel last June. He was in great pain, and my cold words and bad moods started turning him away.
Graduation time was drawing near, and he said he wanted to go back to his hometown. He said that he couldn't put up with me anymore. I was shocked and looked at him in despair.
True love happens only once, but I found it out too late.

A meager diet may give you health and long life, but it's not much fun—and it might not even be necessary. We may be able to hang on to most of that youthful vigor even if we don't start to diet until old age.
Stephen Spindler and his colleagues from the University of California at Riverside have found that some of an elderly mouse's liver genes can be made to behave as they did when the mouse was young simply by limiting its food for four weeks. The genetic rejuvenation won't reverse other damage caused by time for the mouse, but could help its liver metabolize drugs or get rid of toxins.
Spindler's team fed three mice a normal diet for their whole lives, and fed another three on half-rations. Three more mice were switched from the normal diet to half-feed for a month when they were 34 months old—equivalent to about 70 human years.
The researchers checked the activity of 11,000 genes from the mouse livers, and found that 46 changed with age in the normally fed mice. The changes were associated with things like inflammation and free radical production—probably bad news for mouse health. In the mice that had dieted all their lives, 27 of those 46 genes continued to behave like young genes. But the most surprising finding was that the mice that only started dieting in old age also benefited from 70 percent of these gene changes.
"This is the first indication that these effects kick in pretty quickly," says Huber Warner from the National Institute on Aging near Washington, D.C..
No one yet knows if calorie restriction works in people as it does in mice, but Spindler is hopeful. "There's attracting and tempting evidence out there that it will work," he says.
If it does work in people, there might be good reasons for rejuvenating the liver. As we get older, our bodies are less efficient at metabolizing drugs, for example. A brief period of time of dieting, says Spindler, could be enough to make sure a drug is effective.
But Spindler isn't sure the trade-off is worth it. "The mice get less disease, they live longer, but they're hungry," he says. "Even seeing what a diet does, it's still hard to go to a restaurant and say: 'I can only eat half of that'."
Spindler hopes we soon won't need to diet at all. His company, Life Span Genetics in California, is looking for drugs that have the effects of calorie restriction.
According to the passage, which of the following is NOT true？
A．Eating less than usual might make us live longer.
B．If we go on a diet when old, we may keep healthy.
C．Dieting might not be needed. ~
D．We have to begin dieting from childhood.

Robot. It is a word that seems very modem. A word that creates a strong mental picture. A picture of something that looks and acts like a human. Robots are not human, of course. They are machines.
The word robot and robots themselves are less than 100 years old. But humans have been dreaming of real and imaginary copies of themselves for thousands of years. Early people made little human statues out of clay. And they cut wood and stone to look like humans.
What is the future of robots？ The goal of scientists is to create a true humanlike robot. Some experts have described this robot of the future as one that can act independently with the physical world through its own senses and actions. Humans have the ability to see, hear, speak and solve problems. Engineers have built robots that have one or two of these abilities. But it takes a number of big expensive computers to make the robots work.
The biggest problem in creating a humanlike robot is copying human intelligence. The way the human mind works is almost impossible to copy. A simple computer can solve mathematical problems far beyond the ability of even the smartest human mind. But the human mind is better than a thousand supercomputers at speaking, hearing and problem solving. Several American and Japanese companies are working to develop the senses of sight and touch for robots. The development of these senses will make robots much more useful.
However, the most important human ability the most difficult to copy is problem solving. An intelligent robot must be able to change the way it acts when it faces an unexpected situation. Humans do it all the time. Computers must do it for robots. This means computers must have a huge base of information about many things. They must be able to find quickly the needed information in their systems. And they must make choices about how to act. So far, this is beyond the ability of computers.
According to the passage, however intelligent a robot may be, it______.
A．acts as an ordinary animal
B．is nothing but a machine
C．is viewed as a modem myth
D．is regarded as a human being

听力原文：Not until somewhat recently （that is, in terms of human history) did people find
听力原文： Not until somewhat recently (that is, in terms of human history) did people find a need for knowing the time of day. As best we know, 5000 to 6000 years ago great civilizations in the Middle East and North Africa initiated clock-making. With their bureaucracies and formal religions, these cultures found a need to organize their time more efficiently.
The Egyptians were the next to formally divide their day into parts something like our hours. Obelisks (slender, tapering, four-sided monuments) were built as early as 3500 B. C. Their moving shadows formed a kind of sundial, enabling citizens to partition the day into two parts by indicating noon. They also showed the year's longest and shortest days when the shadow at noon was the shortest or longest of the year. Later, markers added around the base of the monument would indicate further time subdivisions.
Another Egyptian shadow clock or sundial, possibly the first portable timepiece, came into use around 1500 B.C. to measure the passage of "hours". This device divided a sunlit day into 10 parts plus two "twilight hours" in the morning and evening. When the long stem with 5 variably spaced marks was oriented east and west in the morning, an elevated crossbar on the east end cast a moving shadow over the marks. At noon, the device was turned in the opposite direction to measure the afternoon "hours".
In the quest for more year-round accuracy, sundials evolved from flat horizontal or vertical plates to more elaborate forms. One version was the hemispherical dial, a bowl shaped depression cut into a block of stone, carrying a central vertical gnomon (pointer) and scribed with sets of hour lines for different seasons. The hemicycle, said to have been invented about 300 B. C. , removed the useless half of the hemisphere to give an appearance of a half bowl cut into the edge of a squared block.
