Pushing children too hard is a really big social problem that seems to be getting worse．Now we have 6-month-olds in music classes and swimming classes．Parents fear that if other children are attending these classes，they will be holding their own children back if they do not enroll，too．

The other extreme，simply taking a laissez-faire approach and letting children do—or refuse to do—whatever they want，is not the answer either，of course．

Dr Taylor emphasizes that parents need to push their children based on what is best for the children，not what is best for themselves．If children understand that an activity is in their best interests，then they will accept it, he finds．

Dr Taylor and other family experts remain pessimistic about the possibilities for widespread social change．“The force of our popular culture，driven by money and superficial（表面上的） values，cannot be resisted，” he says．But change can take place at a“micro-level,” in families and schools．

When changes do occur，the rewards can benefit everyone in the family．One mother supporting this new approach toward parenting mentions the advantages her family experienced after her children cut back on activities．“The biggest thing is that since we have done this，we are rested,” she says．“Not only are our kids rested，because they're not in a ton of stuff, but my husband and I are rested，because we're not driving them everywhere．We weren’t living in the moment when we were always busy．We were living by the schedule．The return on our investment of spending time together has been enormous．”

When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal(揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect(嫌疑犯) who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout(布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”

Drinking a lot of water does not do any good to the body, according to two experts in the United States. In fact, they warn, drinking too much water could be, in certain cases, harmful.

In a study, Dr Stanly Goldfarb and Dr Dan Negoianu, both of the Renal, Electrolyte and Hypertension Division at the University of Pensylvania, the United States, have denied the popular belief that drinking a lot of water clears body toxins（毒素）better, improves skin, and helps reduce weight.

Dr Goldfarb and Dr Negoianu say that they found little proof to back the public opinion that drinking 8 glasses of water every day benefits health. At the same time, they fond little proof of harm in drinking 8 glasses of water every day.

It is widely believed that in some cases-such as athletes, people who live in hot, dry environments, and those with certain medical conditions-drinking a lot of water indeed helps, but no studies have been done to prove the benefits of this practice in average, healthy people, the website medheadlines.com reports.

The study at the University of Pennsylvania also examined reports that some people experienced increased headaches when their consumption（消耗）of water was low. In one small study, which the doctors reviewed, the group drinking the most water reported fewer headaches than the control group, “but the difference in the number of headaches was o small between the two groups as to be considered unimportant.”

The researchers concluded that there is no scientific proof to support that average, healthy people need to drink at least 8 glasses of water each each day.

The website medheadines.com says that, according to an Indian doctor, drinking too much water is harmful. If water enters the body more quickly than it can be removed, problems can occur.

1.What’s the key message delivered in the passage?

A．Drinking too much water might bring harm.

B．Whether to drink enough water makes no difference.

C．Drinking too much water may cause headaches.

D．Average, healthy people should drink more water.

2.We can learn from the passage that 8 glasses of water every day_______ .

A．proves good for the body	B．has scientific proof of harm
C．is sure to reduce headaches	D．is generally considered necessary

3.Who may agree that drinking lots of water helps to lose weight?

A．The two experts.	B．The Indian doctor.
C．The general public.	D．The website.

4.According to the passage, we know that_______.

A．the website medheadlnes.com is developed by an Indian doctor

B．the study was carried out by two experts with an Indian doctor

C．the two experts performed the study at the University of Pennsylvania

D．drinking 8 glasses of water every day can cure certain diseases
