The word“day” has two meanings. When we talk about the number of days in a year,  we are using “day” to mean 24 hours. But when we talk about day and night,  we are using“day” to mean the time between sunrise and sunset. Since the earth looks like a ball,  the sun can shine on only half of it at a time. Always one half of the earth is having day and the other half night. A place is moved from day into night and from night into day over and over by the spinning（旋转）of the earth. At the equator（赤道）day and night are sometimes the same length（长度）. They are each twelve hours long. The sun rises at 6 o’clock in the morning and sets at 6 o’clock in the evening. For six months the North Pole is tilted（倾斜）toward the sun. In those months the Northern Hemisphere（半球）gets more hours of sunlight than the Southern Hemisphere. Days are longer than nights. South of the equator nights are longer than days. For the other six months the North Pole is tilted away from the sun. Then the Southern Hemisphere gets more sunlight. Days are longer than nights. North of the equator nights are longer than days. Winter is the season of long nights. Summer is the season of long days.

There have been many great inventions, things that changed the way we live. The first great invention was one that is still very important today- the wheel. This made it easier to carry heavy things and to travel long distances.
For hundreds of years after that there were few inventions that had as much effect(影响) as the wheel. Then in the early 1800’s the world started to change. There was little unknown land left in the world. People didn’t have to explore(探测) much anymore. They began to work instead to make life better.
In the second half of the 19th century many great inventions were made. Among them were the camera, the light and the radio. These all became a big part of our life today.
The first part of the 20th century saw more great inventions. The helicopter in 1909. Movies with sound in 1926. The computer in 1928. And jet planes in 1930. This was also a time when a new material was first made. Nylon came in 1935. It changed the kind of clothes people wear.
By this time most people had a very good life, Man has a desire to explore again, the world was known to man but the stars were not. Man began looking for ways to go into space. Russia made the first step. Then the United States took a step. Since then other countries, including China and Japan, have made their steps into space.
In 1969 man took his biggest step from the earth. Americans first walked on the moon. This is certainly just a beginning thought. New inventions will someday allow us to do things we have never yet dreamed of.
【小题1】This passage talks mainly about________.
A. why cars were very important

D．movies

A recent study offers a picture of how dangerous it is to get a lift from a teenage driver. Indeed, a 16-year-old driver with three or more passengers is three times as likely to have a fatal（致命的）accident as a teenager driving alone. However, the possibility of death for drivers between 30 and 59 decreases with each additional (added) passenger.
　　It was also found that the death rates for teenage drivers increased greatly after 10 p.m., and especially after midnight. With passengers in the car, the driver was even more likely to die in a late night accident.
　　Robert Foss, a scientist at the University of North Carolina Highway Safety Research Center, says the higher death rates for teenage drivers have less to do with “really stupid behavior” than with just a lack of driving experience. Both he and the author of the study believe that the way to help solve the problem is to have states setting up so-called graduated licensing systems（等级执照制）. A graduated license requires that a teenager first prove that he/she is able to drive in the presence of an adult, followed by a period of driving with a limited number of passengers, before graduating to full driving on his own. About half of the states now have some sort of graduated licensing system in place. The systems have reduced teenage driver crashes（相撞）, according to recent studies.
【小题1】Which of the following situations is most dangerous according to the passage?

A．Adults giving a lift to teenagers on the highway after 10 p.m.

B．A teenager driving after midnight with passengers in the car.

C．Adults driving with three or more teenage passengers late at night.

D．A teenager getting a lift from a stranger on the highway at midnight.

【小题2】According to Robert Foss, the high death rate of teenage drivers is mainly because __.

A．their preference for driving at night

B．their lack of driving experience

C．their careless way of driving

D．their driving with passengers
