A device that stops drivers form falling asleep at the wheel is about to undergo 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 fatigue.

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 squeezing the steering wheel (方向盘). 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.

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 form sleeping

D. has been on sale for 12 months

73. 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.

74. We can learn form 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

75. 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

The Winter Olympics is also called the White Olympics. At this time, many colorful stamps are published to mark the great Games. The first stamps marking the opening came out on January 25, 1932 in the United States for the 3rd White Olympics. From then on, publishing stamps during the White Olympics became a rule. During the 4th Winter Olympic Games a group of stamps were published in Germany in November 1936. The five rings of Olympics were drawn on the front of the sportswear. It was the first time that the rings appeared on the stamps of the White Olympics. In the 1950’s, the stamps of this kind became more colorful.
When the White Olympics came, the host countries(东道国) as well as the non-host countries published stamps to mark those Games. China also published four stamps in February 1980, when the Chinese sports men began to take part in the White Olympics. Japan is the only Asian country that has ever held the White Olympics. Altogether 14,500 million stamps were sold to raise money for this sports meet. Different kinds of sports were drawn on these small stamps. People can enjoy the beauty of the wonderful movements of some sportsmen.

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Have you heard about Leap year? Leap year is a year that has 366 days instead of the usual 365. It normally occurs every four years，always on an even-numbered year．The extra day is added to our shortest month. That is the second month of the year, which in non-leap years has 28 days, two fewer than any other month．    1
We also call Leap year the bissextile year．   2    In our calendar system there is a need for a leap year because the so1ar year (the time it takes the earth to go around the sun once)is actually slightly more than 365 days long. That extra day—Feb 29 every four years—helps correct the difference between our calendar and the solar calendar．
It is said that Leap year was first made part of the calendar by the ancient Roman leader Julius Caesar. His astronomers had calculated the length of the solar year to be 365 days and six hours．So Caesar declared that an extra day be added to the calendar．   3  However，Caesar’s adjustment was not completely accurate because his astronomers’year exceeded the true solar year by eleven minutes and fourteen seconds. By 1582, a difference of ten days had developed between the calendar year and the true solar year. To correct this error，Pope Gregory X III ruled that every fourth year would continue to be a leap year except for century years that could not be divided evenly by 400. By this system，century years such as 1700，1800，and 1900 were not leap years，but the year 2000 was a leap year． 4
People born on Feb 29 they have only one-fourth as many birthday celebrations as most people.
celebrate their growing up a little differently from the rest of us.5     But if they go strictly by the calendar, they have only one-fourth as many birthday celebrations as most people.
A．They acknowledge that they get older each year.
B．when you see Feb 29 on a calendar, you know that year is a leap year.
C．This is its formal, or scientific title.
D．This may seem complicated, but it works．
E. In a leap year, the extra day is added to the second month, giving it 29 instead of the usual 28 days．
F. The leap year was introduced in the Julian calendar in 46 BC.
G．This is done every four years.

The Olympic Games are held _____.

A. for four years B. each four year

C. every four years D. every fourth year
