When someone says, "Well, I guess I'll have to go to face the music," it doesn't mean he is planning to go to a concert. It is something far less pleasant, like being called in your boss to explain why you did this and did that, and why you did not do this or that. Terrible music, indeed, but it has to be faced. At some time or another, every one of us has had to "face the music", especially as children. We can remember father's angry voice: "I want to talk to you!" And only because we did not obey him. What an unpleasant business it was! The phrase "face the music" is known to every American, old and young. It is at least one hundred years old. Where did the expression come from? The first explanation came from the American novelist James Fenimore Cooper. He said, in 1851, that expression was first used by actors while waiting in the wings   to go on stage. After they got their clue  to go on , they often said, "It's time to go to face the music." And that is exactly what they did face the orchestra   which was just below the stage. An actor might be frightened or nervous as he moved on to the stage in front of the audience  that might be friendly, or perhaps unfriendly, especially if he forgot his . But he had to go out. If he did not, there would be no play. So "face the music" came to mean: having to go through something, no matter how unpleasant the experience might be, because you knew you had no choice. Which of the following is NOT true? A) The expression came from James Fenimore Cooper, an American novelist B) The expression has a history of 100 years. C) If someone doesn't obey his boss, he will have to face the music. D) Almost everyone once had an experience to face the music.

We bet that on cold wintry days, many of you love to stay in your warm home and, every now and then, come out into the kitchen for a snack. Unfortunately, plenty of creepy-crawly critters like to do the same thing!     Winter is the time when bugs invade your house without an invitation. The season can be tough for such creatures. In winter the air is cold, the ground is hard and many trees have no leaves. So bugs do what they have to do to survive.     Monarch butterflies head south to warmer climates. Ants crowd in deep underground colonies and eat food they have been storing all year. Many insects go into a deep sleep called diapause. There're different kinds of diapause, but all are similar to hibernation, a time when bigger animals become inactive in the cold. Insects go into an inactive period, too, but it often isn't when the temperature drops.     They rely on more dependable signals in the environment. For example, many insects can tell how much sunlight there's each day. They use that to tell themselves when to shut down. Bugs are cold-blood-ed, meaning that their inside temperature is the same as the outside. They can't move much when it gets below 40 degrees Fahrenheit. So they search for any warm place.     They're looking for protection. These guys have been doing this for 300 million years, so they don't really know they're coming into your house. The home is a recent event in terms of their evolutionary behav-ior. They enter through tiny cracks or come in unnoticed on your clothes or shoes. Remember that they may be invading your homes for warmth and food, but they don't care about humans. According to the text, what is diapause? A) It is the same as the animals' hibernation B) It often appears in warm areas all the year. C) It is done to keep bugs active in winter. D) It is a deep sleep similar to hibernation.

It is 4 o'clock in the early morning. Everything but the computing room on the campus of the university appears as quiet and misty as the mysterious hell. In the computing room, 30 students with sleepy eyes, sit still at their desk, beating the dirty and worn keys. Staring at the colorful screen, they tap continuously for hours. For the other parts in the world, it might be in the middle of the night, nevertheless here time represents nothing. It is an entirely enclosed field. These young computer "hackers" are tracing a sort of stimulus  , a drive so exciting and absorbing that it ignores nearly anything else in their lives and becomes the focus of their being. They are addicted   computer programmers. Some of these students have been glued to the console   for no less than twenty hours even with no break for meals or rest. Some have been sleeping on sofas and chairs in the computing room, trying to struggle for a few moments' rest but hating to get too far away from their addicted machines. It is not necessary for most of these students to be at the computing room in the middle of the night. What they are working belong to no assignments. They remain there because they desire to be -- they can not resist the attraction of the computers. Furthermore, they are in groups instead of being alone. There are hackers at computing rooms all over the country. In the unimaginable way, they focus on nothing but computer. They escape from schooling and live beyond friendship; they might have difficulty being employed, choosing to travel from one computing room to another. They may even give up personal health. "There is one hacker in my memory. We actually had to lift him away from his chair to feed him and arrange him to rest and sleep. We truly worried about his health," says a computing science professor at California University. Professors of computer science are nowadays paying more attention to this hacker phenomenon and are on the watch for future hackers and more and more severe computer addicts. They believe... Which of the following is NOT true of those young computer "hackers"? A) Most of them are top students majoring in computer programming. B) For them, computer programming is the only purpose for their life. C) They can stay with the computer at the computing room for nearly two days. D) Their love for the computer is so deep that they want to be near their machines even when they sleep.

Fish species are expected to shrink in size by up to 24% because of global warming, say scientists. The scientists argue that failure to control greenhouse gas emissions will have a greater effect on marine ecosystems than previously thought. Previous research has suggested that changing ocean temperatures would affect both the distribution and the reproductive abilities of many species of fish. This new work suggests that fish size would also be heavily affected. The researchers built a model to see how fish would react to lower levels of oxygen in the water. As ocean temperatures increase, so do the body temperatures of fish. But, according to lead author, Dr William Cheung, from the University of British Columbia, the lower level of oxygen in the water is key. Warmer waters could decrease ocean oxygen levels and greatly reduce fish body weight. On the other hand, rising temperatures directly increase the metabolic rate of the fish's body function. This leads to an increase in oxygen demand for normal body activities. So the fish will run out of oxygen for growth at a smaller body size. The research team also used its model to predict fish movements as a result of warming waters. The group believes that most fish populations will move towards the Earth's poles at a rate of up to 35km per decade. "So in, say, the North Sea," says Dr Cheung," one would expect to see more smaller-body fish from tropical waters in the future." Taking these factors into consideration, the research team concludes that fish body size will shrink between 14% and 24%, with the largest decreases in the Indian and Atlantic oceans. When compared with actual observations of fish sizes, the model seems to _ what's actually happening in the seas. The researchers looked at two case studies involving North Atlantic cod and haddock. They found that recorded data on these fish showed greater decreases in body size than the models had predicted. Dr Alan Baudron, from the University of Aberdeen, UK, believes smaller-sized fish could seriously... What is the key factor making the fish smaller now? A) The rising body temperatures. B) The lower level of oxygen in the water. C) The increasing metabolic rate. D) The normal body activities.
