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... It can be reasonably inferred from the passage that _ . A) the hacker phenomenon exists only at university computing rooms B) it is not very easy for the "hackers" to find friends or jobs C) university computing rooms are expecting outstanding programmers out of the "hackers" D) the hacker phenomenon is partly due to the lack of the computing rooms

Squawk! Polly wants a cracker! Pretty bird! Pretty bird! These are just a few of the things you might hear coming out of a parrot's mouth. Although parrots seem to be able to talk, they're not really talking like humans. They're not choosing and saying words with specific meanings. Instead, they're simply imitating sounds they've heard. Repeating sounds they've heard before-often many times-is called mimicry. The "talking" we hear from parrots can consist of imitations of all sorts of sounds, from spoken words to creaking doors to barking dogs. They're not really "talking", but it doesn't mean that parrots' mimicry isn't impressive. Did you know that parrots don't have vocal cords like humans? It's true! Instead, parrots use muscles in their throat to direct airflow through their mouths to mimic the sounds they hear around them. Parrots, such as African Greys and Amazons, aren't the only birds that can learn to imitate sounds, including human voices. Some other birds known for their ability to "talk" include Indian Ringneck Parakeets, Budgies and Cockatiels. If you're wondering why some birds imitate sounds they hear, it's because they're social animals. They feel a need to be able to interact with those around them. When kept as pets, these birds see their owners as their family and want to communicate with them. Since a human owner usually can't learn a bird's "language", the bird instead tries to learn the language of its owner. Although these birds are often quite intelligent, imitation is still the best that they can manage. Mimicry becomes a way for them to get attention and interact with their owners. If you want to have a bird that talks as a pet, the best thing to do is to find a bird that already knows how to imitate sounds. Even if a bird knows how to imitate a few sounds, though, you'll still need to spend lots of time training it and providing positive interactions to encourage more "talking ". You can get a bird to talk more by -. A) showing your kindness to it B) training it in a certain way C) directing airflow through its mouth D) making it imitate another bird
