Passage 70

(山东省淄博市2010届高三上学期期末考试)

C

The more television that a three-year-old watches, the more likely he or she is to behave aggressively, according to a U.S. study.

Just having the TV on in the background, even if the child wasn’t watching it, was also linked to aggressive behavior although the relationship wasn’t as strong, said the researchers.

“Parents should be smart about TV use,” researcher Jennifer Manganello from the University at Albany, State University of New York, told Reuters Health. “They should limit the time that children use TV, pay attention to the content of TV programs, and consider how TV is used throughout the home.”

The study looked at 3,128 women from 20 U.S. cities who had a child between 1998 and 2000. While there was some diversity of education among the study participants, one-third hadn’t graduated from high school.

Two-thirds of the mothers said their three-year-old watched more than two hours of TV a day, and the average viewing time for children was around three hours. On average, the TV was on for about five additional hours on a typical day.

After accounting for factors known to be associated with aggressive behavior, such as living in a violent neighborhood or having a mother who suffers from depression, TV watching and household TV time were both still significantly associated with aggressive behavior, such as hitting others, having angry moods, being disobedient, and screaming a lot.

The American Academy of Pediatrics(小儿科)recommends no TV at all for children two and younger, and two hours a day or less for older kids, lead researcher Jennifer Manganello and her team from the Tulane University School of Public Health noted in their report.

Passage 69

(福建省三校2010届高三上学期期中联考)

D

Around the age of 40, honest people may already admit to noticing changes in their mental abilities. This is the beginning of a gradual decline that in all too many of us will end with full-blown dementia(痴呆).

However, a few drugs that might do the job, known as “cognitive enhancement(认知增强)”, are already on the market, and a few dozen others are on the way. Perhaps the best-known is modafinil. Licensed to treat narcolepsy(嗜眠症), the condition that causes people to suddenly fall asleep, it has notable effects in healthy people too. Modafinil can keep a person awake and his or her attention fixed for 90 hours straight, with none of anxiety, nervousness and bad concentration. In fact, with the help of modafinil, people who can hardly go to sleep can perform even better than their well-rested, un-medicated(未服药的) selves.

It’s an open secret that many, perhaps most, prescriptions for modafinil are written not for people who suffer from narcolepsy, but for those who simply want to stay awake. Similarly, many people are using Ritalin not because they suffer from attention problem or any other disorder, but because they want superior concentration during exams or heavy-duty activities.

Some drugs have also been specially designed to improve memory. Many of these seem to work, and without any major side effects. So why aren’t we all on cognitive enhancers already?

“We need to be careful what we wish for,” says Daniele Piomelli at the University of California at Irvine. Repairing and improving memory may have unwanted effects, he warns. “Eventually we may end up remembering things we don’t want to.”

62．What can make “Nowcasts” a reality according to the passage?

A．Scientific and technological advances.　 B．Advanced computer programs.

C．Computer scientists.　　　　　　　　 D．Meteorologists.

61．The word “Nowcast” in Paragraph 3 means ________.

A．a network to collect storm data　　　 B．a way of collecting weather data

C．a more advanced system of weather observation

D．a forecast which can predict weather in the small area

60．Why can’t traditional computer models predict short-lived local storms?

A．The weather data people collect are often wrong.

B．Detailed weather data in some small areas are not available.

C．The computers are not advanced enough to predict them. D．The computers are not used to forecast specific local events.
