Passage 37

(吉林省实验中学2007届高三第四次模拟考试A篇)

LONDON- “Everyone else has one!” Lucy declared to her parents, trying to get a mobile phone as a gift for 14^th birthday. Her parents gave in.

Curious to know how her daughter would use the phone, Jane Bidder, the mother, followed Lucy to the school bus in the morning. The bus seats 20, of whom half have a mobile phone. One rings and several adolescent owners fumble with their bags.

Many parents have just come to realize that the mobile phone is no longer for traveling businessmen-it is as likely to be found in school bags.

The mobile phone seems to have become something essential for today’s teens in Britain, according to a survey published last week, by NOP, a leading market research company in Britain. Research found that 66 percent of 16 – year – olds now have access to a mobile phone.

The mobile phone has been turned into a secret messaging service by teen users. When they are talking on the mobile, their parents are not able to eavesdrop on the second line.

The interview with 2,019 young people aged 7 to 16 found that they favor the text messaging service because they offer a secret way of keeping in touch. The days of secret notes in the classroom are dying out.

For example, “cul” means “see you later”; “lol” means “laugh out loud’; and “2nite” is the abbreviation of “tonight”. All these are based on shorthand phrases on the Internet.

Many schools have banned students using mobile phones. But they are not very successful. Still phones ring in the class and disturb study. Besides, people are worried about the health risk to kids using mobile phones.

Scientists believe children are especially vulnerable(易受伤的)mobile radiation.

Passage 36

(北京市北大附中2007年5月高三最后适应测试E篇)

Even facts “forgotten” by people during a busy day may be retrieved if this is followed by a good night’s sleep.

Researchers from the University of Chicago asked volunteers to remember simple words．Many found their memories letting them down towards the end of the day, but the following morning, those who had slept well could recall much more.

Researchers, writing in the journal Nature, said the brain could “rescue” lost memories during the night.

When the brain is first asked to remember something that memory is laid down in an “unstable” state, meaning that it is possible that it could be lost．At some point, the brain consolidates those it deems important into a “stable”, more permanent state．However, the Chicago researchers suggested that it was possible for a “stable” memory to be made “unstable” again．This would mean that memories could be modified then filed away again in the face of new experiences.

The 12 volunteers tested in the experiment were played words created through a speech synthesizer which were purposely difficult to understand．Initially, the written version of the word　 from the audio version only．Tests revealed that the ability to recall the right word tended to tail off as the day ended.

However, when the volunteers were retested after a good night’s sleep, they were able to recall some words that they had “ forgotten” the previous evening.

Dr Daniel, one of the study authors, said: “Sleep consolidates memories, protecting them against subsequent interference or decay．Sleep also appears to “recover” or restore memories.” He said: “If performance is reduced by decay, sleep might actively recover what has been lost.”

Dr Karim Nader, from the Department of Psychology in McGill University in Montreal, said: “Memory research is undergoing a transformation---no longer is memory thought to be a hard-writing of the brain, instead it seems to be a process of storage and restorage.”

Sleep helps some memories “mature” and also prunes out unimportant memories.
