　　Cancer is feared by everyone. And this fear is reaching epidemic***流行性*** proportions. Not the disease itself — there is no such thing as a cancer epidemic. Except for lung cancer, mostly caused by cigarette smoking ,the incidence rates are leveling off, and in the case of some kinds of cancer are decreasing. But the fear of cancer is catching, and the country stands at risk of an anxiety, The earth itself is coming to seem like a huge carcinogen***致癌物***. The ordinary, more or less scientific statement that something between 80 and 90 percent of all cancers are dun to things in the environment is taken to mean that none of us will be safe until the whole environment is “cleaned up.” This is not at all the meaning.

　　The 80-percent calculation is based on the unthinkable differences in the incidence of cancer in various societies around the world — for example, the high proportion of liver cancer in Africa and the Far East, stomach cancer in Japan, breast cancer in Western Europe and North America, and the relatively low figures for breast cancer in Japan and parts of Africa and for liver cancer in America. These data indicate there may be special and specific environmental influences, largely based on personal life-style, that determine the incidence of various forms of cancer in different communities — but that is all the data suggest. The overall incidence of cancer, counting up all the cases, is probable roughly the same everywhere.

　　1.Which of the following is closest to meaning to the phrase “leveling off”?

　　A***positive

　　B***negative

　　C***neutral

　　InfraGard is a grass-roots effort to respond to the need for cooperation and collaboration in countering the threat of cyber crime and terrorism to private businesses and the government. By the end of September, there will be InfraGard chapters in all 50 states, Calloway said. With advice from the FBI, each local chapter will be run by a board of directors that includes members of private industry, the academic community and public agencies. Bands, utilities, and other businesses and government agencies will use a secure Web site to share information about attempts to hack into their computer networks. Members can join the system free. A key feature of the system is a two-pronged method of reporting attacks.

　　A "sanitized" description of a hacking attempt or other incident-one that doesn't reveal the name or information about the victim-can be shared with the other members to spot trends. Then a more detailed description also can be sent to the FBI's computer crimes unit to interfere if there are grounds for an investigation. Cyber crime has jumped in recent years across the nation, particularly in hotbeds of financial commerce and technology like Charlotte. "Ten years ago, all you needed to protect yourself was a safe, a fence and security officers," said Chris Swecker, who is in charge of the FBI's Charlotte office. "Now any business with a modem is subject to attack." FBI agents investigate computer hacking that disrupted popular Web sites including Amazon. com, CNN and Yahoo!

　　several North Carolina victims have been identified this year. The investigation has also identified computer systems in North Carolina used by hackers to commit such attacks. Prosecutions of hackers have been hampered by the reluctance of companies to report security intrusions for fear of bad publicity and lost business. Meanwhile, too many corporations have made it too easy for criminals by sacrificing security for speed and accessibility. Jack Wiles, who will lead the local InfraGard chapter's board, said a recent report estimated 97 percent of all cyber crime goes undetected. Wiles, a computer security expert, has a firewall on his personal computer to prevent hackers from getting into his files. "I get at least one report a day that somebody was trying to get into my computer," he said, "the Net is a wonderful place, but it's also a dangerous one."
