Passage 2 A great deal of attention is being paid today to the socalled digital divide — the division of the world into the info(information) rich and the info poor. And that divide does exist today. My wife and I lectured about this looming danger twenty years ago. What was less visible then, however, were the new, positive forces that work against the digital divide. There are reasons to be optimistic.

There are technological reasons to hope the digital divide will narrow. As the Internet becomes more and more commercialized, it is in the interest of business to universalize access — after all, the more people online, the more potential customers there are. More and more governments, afraid their countries will be left behind, want to spread Internet access. Within the next decade or two, one to two billion people on the planet will be netted together. As a result, I now believe the digital divide will narrow rather than widen in the years ahead. And that is very good news because the Internet may well be the most powerful tool for combating world poverty that we've ever had.

Of course, the ue of the Internet isn't the only way to defeat poverty. And the Internet is not the only tool we have. But it has enormous potential.To take advantage of this tool, some impoverished countries will have to getover their outdated anticolonial prejudices with respect to foreign investment. Countries that still think foreign investment is an invasion of their sovereignty might well study the history of infrastructure (the basic structural foundations of a society) in the United States. When the United States built its industrials infrastructure, it didn't have the capital to do so. And that is why America's Second Wave infrastructure — including roads, barbors, highways, prots and so on — were built with foreign investment. The English, the Germans, the Dutch and the French were investing in Britain's former colony. They financed them. Immigrant Americans built them. Guess who owns them now? The Americans. I believe the same thing would be true in places like Brazil or anywhere else for that matter. The more foreign capital you have helping you build your Third Wave infrastructure, which today is an electronic infrastructure, the better off you're going to be. That doesn't mean lying down and becoming fooled, or letting foreign corporations run uncontrolled. But it does means recognizing how important they can be in building the energy and telecom infrastructures needed to take full advantage of the Internet.

A getting worse because of the Internet

B the rich countries are responsible for

C the world must guard against

D considered positive today

Of the many problems in the world today, none is as widespread, or as old, as crime. Crime has many forms, including crimes against property, person, and government. Crime, in all its forms, penetrates every layer of society and touches every human being. You may never have been robbed, but you suffer the increased cost of store- bought items because of others’shoplifting.

Your house is not worth as much today as it was a few years ago because of the increased crime rate in your neighborhood. Perhaps your business is not doing as well as it used to because tourism is down due to increased terrorism in your part of the world.

Crime, especially violent crime, has risen to a point where many people are afraid to walk al one in their own neighborhoods, afraid to open their door after dark, afraid to speak out and voice their own opinions. Some citizens have reacted by arming themselves with various weapons, legal and illegal, to defend themselves. Citizen groups have taken the law into their own hands by forming their own vigilante groups to administer judgment when they feel that their criminal justice system has not performed its duty.

Experts argue whether the number of crimes committed is actually on the rise or whether there is simply a rise in the number of crimes reported. This issue is particularly true in cases of marriage violence, the abuse of spouse or children. Throughout much of history, cases of family violence and neglect often went unreported because of the attitude of society, which considered family matters to be private.

Other experts argue about who is really to blame for criminal behavior. the individual or society. Researchers in the United States and Canada have identified several factors in society that contribute to the crime rate: massive urbanization, unemployment and poverty, and a large immigrant population. Other countries are more affected by factors such as politics, government corruption, and religion.

Text 4There have been rumors. There’s been gossip. All Hollywood is shocked to learn that Calista Flockhart, star of Fox’s hit TV show Ally McBeal, is so thin. And we in the media are falling all over ourselves trying to figure out whether Flockhart has an eating disorder, especially now that she has denied it. Well, I’m not playing the game. If the entertainment industry really cared about sending the wrong message on body image, it wouldn’t need so many slender celebrities in the first place.

But the fact remains that 2 million Americans—most of them women and girls—do suffer from eating disorders. In the most extreme cases they literally starve themselves to death. And those who survive are at greater risk of developing brittle bones, life-threatening infections, kidney damage and heart problems. Fortunately, doctors have learned a lot over the past decade about what causes eating disorders and how to treat them.

The numbers are shocking. Approximately 1 in 150 teenage girls in the U. S. falls victim to anorexia nervosa, broadly defined as the refusal to eat enough to maintain even a minimal body weight. Not so clear is how many more suffer from bulimia, in which they binge on food, eating perhaps two or three days’ worth of meals in 30 minutes, then remove the excess by taking medicine to move the bowels or inducing vomiting. Nor does age necessarily protect you. Anorexia has been diagnosed in girls as young as eight. Most deaths from the condition occur in women over 45.

Doctors used to think eating disorders were purely psychological. Now they realize there’s some problematic biology as well. In a study published in the Archives of General Psychiatry recently, researchers found abnormal levels of serotonin, a neurotransmitter in the brain, in women who had been free of bulimia for at least a year. That may help explain why drugs have allowed a lot of people to stop swallowing in large doses of food. Unfortunately, the pills don’t work as well for denial of food. Nor do they offer a simple one-stop cure. Health-care workers must re-educate their patients in how to eat and think about food.

How can you tell if someone you love has an eating disorder? “Bulimics will often leave evidence around as if they want to get caught.” Says Tamara Pryor, director of an eating-disorders clinic at the University of Kansas in Wichita. Anorexics, by contrast, are more likely to go through long periods of denial.
