| For the past six years, crime rates
have been falling all over America. In some big cities, the fall has been
extraordinary. Between 1994 and 1997 in New York city violent crime fell by 39%
in central Harlem and by 45% in the once-terrifying South Bronx. The latest
figures released by the FBI, for 1997, show that serious crime continued to fall
in all the largest cities, though a little more slowly than in 1996. Violent crime fell by 5% in all, and by slightly more in cities with over 250,000 people. Property crimes have fallen, too, by more than 20% since 1980, so that the rates for burglary and car-theft are lower in America than they are in supposedly more law-abiding Britain and Scandinavia. And people have noticed. In 1994, 30% of Americans told pollsters that crime was the most important challenge facing the country. In A. The last sentence in the 1st paragraph. B.

A number of devices are available to help a person quit smoking. Nicotine (尼古丁) patches are small, nicotine-containing adhesive (粘着性的) discs applied to the skin. The nicotine is slowly absorbed through the skin and enters the bloodstream (血流). Over time, the nicotine dose is reduced and eventually the desire for nicotine is eased. Nicotine gum (口香糖) works in a similar manner, providing small doses of nicotine when chewed (咀嚼). The benefits of giving up smoking include the immediate reduction of harm to the health of the smoker and easier admission to social activities and institutions that ban smoking. In a 1988 report, the U.S. Surgeon General declared cigarette smoking to be more harmful and expensive than the use of cocaine (可卡因), alcohol, or heroin. Recent evidence supports this claim.
