Since the early 1980s, scientists have revealed some 40 human genes involved in cancer. These genes are essential for normal growth, but can be subverted to cause a tumor.
Dr. Jorge Yunis of the University of Minnesota Medical School in Minneapolis has found that 70 percent of oncogenes, or cancer-causing genes, are located near inherited weak points on chromosomes(染色体). Varying from individual to individual, vulnerable to chemical carcinogens(致癌剂), X rays and other cancer-inducing agents.
"If a chromosome snaps apart in the immediate vicinity of an oncogene," says Yunis, "normal genetic control mechanisms could break down and the stage would be set for the formation of cancer." Younis has shown that such a sequence occurs at the beginning of numerous leukemias (白血病), lymphomas(淋巴瘤) and some tumors of the lung, colon(结肠) and breast.
Yunis and other investigators have found that petroleum-based products--notably pesticides and insecticides-damage specific sites on at least two of the 23 pairs of human chromosomes that carry genetic information. Similarly, tobacco smoke tends to attack a part of another chromosome.
From paragraph 1, we know that some 40 genes involving in cancer are ______. ()
A．harmful to the human body
B．necessary to the human body
C．the elements that form. cancer
D．useless to the human body

It is 3 A. M. Everything on the university campus seems ghostlike in the quiet, misty darkness -- everything except the computer center. Here, twenty students untidy and blurred-eyed, sit transfixed at their consoles([计]挖制台), tapping away on the terminal keys. With eyes glued to the video screen, they tap on for hours. For the rest of the world, it might be the middle of the night, but here time does not exist. This is a world unto itself. These young computer "hackers" are pursuing a kind of impulse, a drive so consuming it overshadows nearly every other part of their lives and forms the focal point of their existence. They are compulsive computer programmers. Some of these students have been at the console for thirty hours or more without a break for meals or sleep. Some have fallen asleep on sofas or chairs in the computer center, trying to catch a few winks but hate to get too far away from their beloved machines.
Most of these students don't have to be at the computer center in the middle of the night. They aren't working on assignments. They are there because they want to be -- they are irresistibly drawn there.
And they are not alone. There are hackers at computer centers all across the country. In their extreme form, they focus on nothing else. They flunk(考试不及格)out of school and lose contact with friends; they might have difficulty finding jobs, choosing instead to wander from one computer center to another. They may even decline personal cleanliness.
"I remember one hacker. We literally had to carry him off his chair to feed him and put him to sleep. We really feared for his health," says a computer science professor at MIT.
Computer science teachers are now more aware of the implications of this hacker phenomenon and are
on the lookout for potential hackers and cases of computer addiction that are already severe. They know that the case of the hackers is not just the story of one person's relationship with a machine. It is the story of a society's relationship to the so-called thinking machines, which are becoming almost everywhere.
We can learn from the passage that those at the computer center in the middle of the night are ______.
A．students preparing for tests
B．students using computers to finish assignments
C．excellent computer science majors
D．students deeply fascinated by the computer

All of us have felt pain. We have cut ourselves. We have been burned. Or we have had headaches. Some of us suffer pain rarely_______46)
Pain can take complete control of our body and mind, making it impossible to move and even to think. Yet we need pain. Without it, we would not know if we have hurt ourselves. It is our body's warning system_________47)
Pain is the most common reason we go to a doctor. It is the most common reason we take medicines. Until recently, however, most doctors knew of only a few drugs that stopped some pains_________(48) But new knowledge about the process of pain is helping them to control pain better.
Scientists have learned that the sense of pain is made up of both chemical and electrical signals_________(49) Scientists also have learned that the nervous system sends two different kinds of pain messages to the brain: one very fast, the ether slow.
The first message is the warning signal. It moves at a speed of 30 meters a second. In less than a second, the brain understands that part of the body is hurt and how badly it is injured________(50) It tells us not to use the injured part until it heals.
A．And others have painful attacks all the time.
B．These signals travel from nerve cells in the injured area, up the spinal cord (脊髓) to the brain, and back down again.
C．It tells us that we are injured and should do something about it.
D．They knew little about the process of pain itself.
E．The other message moves at a speed of only one meter a second.
F． And they send the second, slower message of pain to the brain.
