A device that stops drivers from falling asleep at the wheel is about to undergo(接受) testing at Department of Transport laboratories and could go on sale within 12 months.
The system, called driver Alert, aims to reduce deadly road accidents by 20%--40% that are caused by tiredness. Airline pilots can also use it to reduce the 30% of all pilot-error accidents that are related to tiredness.
Driver Alert is based on a computerized wristband. The device, worn by drivers or pilots gives out a sound about every four minutes during a car journey. After each sound the driver must respond by pressing the steering wheel. A sensor in the wristband detects this pressing action and measures the time between the sound and the driver’s response.
Tiredness is directly related to a driver’s response time. Usually, a watchful driver would take about 400 milliseconds to respond, but once that falls to more than 500 milliseconds, it suggests that the driver is getting sleepy.
In such cases the device gives out more regular and louder sounds, showing that the driver should open a window or stop for a rest. If the driver’s response continues to slow down, the sounds become more frequent until a nonstop alarm warns that the driver must stop as soon as possible.
The device has been delivered to the department’s laboratories for testing. If these tests, scheduled for six months’ time, are successful, the makers will bring the product to market within about a year.
68. How should a driver respond to the sounds from Driver Alert?
A. By sounding a warning.   B. By touching the wristband.
C. By checking the driving time. D. By pressing the steering wheel.
69. We can learn from the text that the driver needs to stop for a break when his response time is ________
A. about 400 milliseconds    B. below 500 milliseconds
C. over 500 milliseconds      D. about 4 minutes
70. When the driver gets sleepy while driving, Driver Alert ______.
A. moves more regularly      B. stops working properly
C. opens the window for the driver      D. sounds more frequently and loudly
71. According to the text, Driver Alert ______.
A. aims to reduce tiredness-related accidents
B. has gone through testing at laboratories
C. aims to prevent drivers from sleeping
D. has been on sale for 12 months

Do you want to live a happier, less stressful (有压力的) life?
Try laughing for no reason at all. That’s how thousands of people start their day at Laughter Clubs around the world – and many doctors now think that having a good laugh might be one of the best ways to stay healthy.
The first Laughter Club was started in Mumbai, India, in 1995 by Dr Madan Kataria. “Young children laugh about 300 times a day. Adults laugh between 7 and 15 times a day,” says Dr Kataria. “Everyone’s naturally good at laughing – it’s the universal language. We want people to feel happy with their lives.” There are now more than 500 Laughter Clubs in India and over 1,300 worldwide.
Many doctors are also interested in the effects (效果) of laughter on our health. According to a 5 – year study in the body. Laughter improves our health against illness by about 40%.
So, what happens at a Laughter Club? I went along to my nearest club in South London to find out. I was quite nervous at the beginning of the class, to be honest – I wasn’t interested in laughing with a group of strangers, and I was worried about looking stupid. Our laughter teacher told us to clap our hands and say “ho ho ho, ha ha ha,” while looking at each other. However, our bodies can’t tell the difference between fake laughter and real laughter, so they still produce the same healthy effects.
Surprisingly, it works! After ten minutes everybody in the room was laughing for real – and some people just couldn’t stop! At the end of the class I was surprised by how relaxed and comfortable I felt. So if you’re under stress, then start laughing. You might be very pleased with the results!
In which country was the first Laughter Club started?

A.Britain. B.America. C.Australia. D.India.

How did the writer feel at the beginning of the class?

A.Surprised. B.Pleased. C.Nervous. D.Stressful.

When did the people in the club begin to laugh for real?

A.After a few minutes. B.After a few hours.
C.After a few seconds. D.After a few days.

Which of the following is true according to the passage?

A.Fake laughter and real laughter are both good for health.
B.40% of the people in Laughter Clubs are good friends.
C.Adults laugh more often than children in a day.
D.Laughing is the best way to prevent illness.

We had known for along time that flowers of different plants open and close at different time of day. Yet no one really understands why flowers open and close like this at special time. The question is not as simple as we might think, as recent experiments have shown. In one experiment, flowers were kept in constant (持续的)darkness. We might expect that the flowers ,without any information about the time of the day, did not open as they usually do. In fact, they continue to open at their usual time. This shows that they have some special ways of knowing the time. Their sense(感觉) time does not depend on information from the outside world. It is inside them: a kind of "inner (内部的)clock". This discovery may not seem to be very important. However, it is later found that not just plants but animals have this "inner clock" which control(控制)the working of their bodies and influences their activities. Human beings, then, are also influenced by it. Whether we wish or not, itaffectssuch things in our life as our need for sleep or need for food.
