Celebrating Sleep

World Sleep Day, observed on 21 March, was created to bring attention to the growing number of sleep problems worldwide. Sleep is a natural part of human life, but many people in the modern world ignore its importance. As a result, sleep problems are increasingly common.In 2002, scientists at the University of Athens in Greece conducted a survey of over 35,000 people in 10 countries around the world, including China, Belgium and South Africa. Of the people that responded to the survey, 24 percent said that they did not sleep well, and based on their responses, 31.6 percent were diagnosed with insomnia(失眠) and another 17.5 percent were diagnosed with borderline(边界线) insomnia. In addition, 30.7 percent of survey respondents reported visiting a doctor for help with sleep problems and 11.6 percent said that they felt very sleepy during the day.

Overall, the survey found that many people suffer the effects of poor quality sleep, some examples of which are being unable to fall asleep and waking up in the middle of the night. The main factors causing these problems are pressure from school or work and a fast pace of life, but noise pollution and light pollution also interfere with sleep and contribute to poor quality sleep. The survey’s findings are particularly troubling because large numbers of people were found to have difficulty sleeping at night. The short-term effects of this are tiredness and trouble concentrating. If this happens for a long time, the risk of gaining weight and having a heart attack may increase.

There are many things you can do to improve the quality of your sleep. First, you should have regular sleep habits. Try to go to bed and wake up around the same time each day. You also need to make your bedroom a cool, dark, quiet place to sleep so that heat, light and noise do not disturb you. At night, you should also avoid things that contain caffeine, such as chocolate, coffee, tea and many soft drinks, as caffeine may keep you from sleeping.

Getting a good night’s sleep is important for everyone. By following the advice above, you can rest better at night and work better during the day.

【题目】Many people have long dreamed of being able to fly around as simply as riding a bicycle. Yet the safety and strength of a flying bike was always a big problem.

Over the past 10 years, developments in technology have moved the dream of personal flying vehicles closer to reality. Now, two groups of inventors say such vehicles may be available very soon.

Grant Stapleton from Malloy Aeronautics says the Hoverbike, which is able to get in and out of small spaces very quickly, will be a truly personal flying vehicle. "It can be moved across continents very quickly because it can be folded and packed," he adds.

Mr. Stapleton says safety was the company's main concern when developing the Hoverbike. He ays the designers solved the safety issue by using overlapping rotors (折叠旋翼) to power the vehicle. The company is testing both a one-third size model and a full-size prototype (原型) of the Hoverbike.

Inventors say their Hoverbike will most likely be used first by the police and emergency rescue teams.

In New Zealand, the Martin Aircraft Company is also testing a full-size prototype of its personal flying bike, called Jetpack. It can fly for more than 30 minutes, up t0 1,000 meters high and reach a speed of 74 kilometers per hour.

Peter Coker is the CEO of Martin Aircraft Company. He said Jetpack "is built around safety from the start, " In his words, "reliability is the most important part of it. We have safety built into the actual structure itself, very similar to a Formula One racing car. "

Jetpack uses a gasoline-powered engine that produces two powerful jet streams. Mr. Coker says it also has a parachute (降落伞) that can be used should there be an emergency.

"It opens at a very low altitude and actually saves both the aircraft and the pilot in an emergency," he adds.

【1】Which of the following words can best describe the Hoverbike?

A. Powerful. B. Fast. C. Portable. D. Available.

2What make(s) flying vehicles seem practical now?

A. Modem technology. B. New safety rules.

C. Love of cycling. D. Public concerns.

3Who are expected to use the Hoverbike first?

A. People who dream of flying.

B. People who really love cycling.

C. People who design the bike.

D. People who serve public purposes.

4What's the main concern the two companies share?

A. Safety. B. Speed. C. Size. D. Design.

【题目】Ever walked to the shops only to find, once there, you’ve completely forgotten what you went for? Or struggled to remember the name of an old friend? For years we’ve accepted that a forgetful brain is as much a part of aging as wrinkles and gray hair. But now a new book suggests that we’ve got it all wrong.

According to The Secret Life of the Grown-up Brain, by science writer Barbara Strauch, when it comes to the important things, our brains actually get better with age. In fact, she argues that some studies have found that our brain hits its peak between our 40s and 60s much later than previously thought.

Furthermore, rather than losing many brain cells as we age, we keep them, and even produce new ones well into middle age. For years it’s been assumed that brain, much like the body, declines with age. But the longest, largest study into what happens to people as they age suggests otherwise.

This continuing research has followed 6,000 people since 1956, testing them every seven years. It has found that on average, participants performed better on cognitive (认知的) tests in their 40s and 50s than they had done in their 20s. Specifically, older people did better on tests of vocabulary, verbal memory (how many words you can remember) and problem solving. Where they performed less well was number ability and perceptual speed how fast you can push a button when ordered. However, with more complex tasks such as problem-solving and language, we are at our best at middle age and beyond. In short, researchers are now coming up with scientific proof that we do get wiser with age.

Neuroscientists are also finding that we are happier with aging. A recent US study found older people were much better at controlling and balancing their emotions. It is thought that when we’re younger we need to focus more on the negative aspects of life in order to learn about the possible dangers in the world, but as we get older we’ve learned our lessons and are aware that we have less time left in life: therefore, it becomes more important for us to be happy.

【1Barbara Strauch probably agrees that ______.

A. people’s brains work best between their 40s and 60s

B. the young are better at handling important things

C. aging leads to the decline of the function of the brain

D. wrinkles and gray hair are the only symbols of aging

【2The continuing research has found older people perform better on ______.

A. perceptual speed B. vocabulary tests

C. number ability D. body balance

【3People are happier with aging because ______.

A. they know how to share feelings

B. they learn to value the time left

C. they cannot focus on negative aspects

D. they do not realize the possible dangers

【4】What is the main idea of the passage?

A. People get happier with age.

B. People get more self-aware with age.

C. People get wiser with age.

D. People get more forgetful with age.
