Passage 1

Ideas about education are changing in the United States. Education today is not just a high school diploma or a college degree. Many adults are not interested in going to college. They are interested in other kinds of learning. For them, learning does not end with a diploma.
Continuing education gives these adults the opportunity to increase their knowledge about their own field or to learn about a new field. It also gives them a chance to improve their old skills or to learn new ones.
Continuing education classes give some adults the chance to learn new skills. There are usually many kinds of classes to choose from, foreign cooking, auto repair, or furniture repair. These are only some of the classes available.
Some adults take classes for fun or because the class will be useful for them. For example, they can choose a class in almost any language as a second language. There are classes in first aid or classes in sewing. There are also many other types of classes to choose from.
Other adults take continuing education classes to improve their own lives because they want to feel better about themselves. Overweight people can find exercise classes or classes in nutrition. Others can learn how to be good parents, or how to get along with other people.
There are many opportunities for adults to continue their learning. Almost any community college or public school system has a continuing education program. There are classes in schools, community buildings, or churches. Most classes are in the evening, so working people can attend. The classes are usually small, and they are inexpensive.
Thousands of people register for continuing education classes each year. They receive no diploma or certificate, and no grade for most of the classes they attend. For them, learning is something they do because they want to.
Lots of people attend continuing education classes because （）.

A．the classes will help them feel better about themselves
B．there are many courses they can choose from
C．they can also go to church at the same time
D．learning is something they are interested in

Passage 2

Basketball is a sport enjoyed by millions of fans in at least 100 countries. It’s one of the best-known sports in the world. It all began in 1891.
Dr. James A. Naismith, the father of basketball, was an instructor at a YMCA(基督教) Training school. The school trained people to work in YMCAs. Officials at the school were concerned about the low attendance during the winter months. They felt that people didn’t attend then because the school did not have a good winter sports program. So they asked Dr. Naismith for help. He came up with a new indoor game.
Naismith studied current games. He found that all the most popular games used a ball. So a ball would be a part of his new game, he decided. But kicking the ball or hitting it would be too rough for indoor. So he put 2 peach baskets up on poles. The players had to try to throw a soccer ball into them. Naismith then made thirteen rules for the game. 12 of them are still in use today. Just 7 years after the game began, professional basketball teams were formed.
And that’s how basketball was born.
Which of the following would be the best title for the passage ______.

A．The Birth of Basketball
B．YMCA and Basketball
C．Basketball——an Indoor Game
D．A Winter Sports Program

Passage 3

More than 30000 drivers and front seat passengers are killed or seriously injured each year. At a speed of only 30 miles per hour it is the same as falling from a third floor window. Wearing a seat belt saves lives; it reduces your chance of death or serious injury by more than half.
Therefore drivers of front seat passengers over 14 in most vehicles must wear a seat belt. If you do not, you could be fined up to ￡50. It will not be up to the drivers to make sure you wear your belt. But it will be the driver’s responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.
However, you do not have to wear a seat belt if you are reversing your vehicle or you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it. Make sure these circumstances apply to you before you decide not to wear your seat belt. Remember you may be taken to court for not doing so, and you may be fined if you cannot prove to the court that you have been excused from wearing it.
This text is taken from ______.

A．a medical magazine
B．a police report
C．a legal document

Passage 4

Once they are more than a month old, babies seem to learn readily. (84) Moreover, solving a problem or discovering the relationship between their own actions and an event in the external world seems to have its own rewards for infants.
The pleasure involved in such an experience seemed obvious in one study of two-to-four- month-old infants who were given a chance to control a yellow-and-green mobile. One of these mobiles was suspended above each infant, who play in a crib (小床) with a ribbon attached to one ankle. The other end of the ribbon was attached to the hook from which the mobile was suspended. As the infants moved about, waving their arms and kicking their legs, they learned to connect the motion of one leg with the bobbing(跳动) of the mobile. As they smiled and gurgled(咯咯的笑) at the moving mobile, the infants began to kick the leg attached to the mobile forcefully and precisely and only that leg. Apparently, they enjoyed controlling the mobile, for they would continue for as long as 45 minutes.
Nor is this pleasure in mastery limited to infants. In an experiment with fifth and sixth graders, the children were asked to solve some word puzzles that varied in difficulty. The youngsters smiled more, and reported far more pleasure, when they solved a difficult puzzle than any easy one. The implication is that human beings of any age-from infancy to old age- derive pleasure from intellectual mastery.
In the experiment, the infants ______.

A．kicked their legs randomly all the time
B．kicked the leg controlling the mobile most of the time
C．attached the colorful ribbons to their own legs
D．felt very tired and lost their interest soon
