A public good is one that a person can use without reducing the use of it for another person. One of the best examples of a public good is national defense. One person can benefit from our national defense without reducing another person's benefits. In fact, it is difficult to keep any person in our society from enjoying the benefits of national defense.

The market system does not work well in producing public goods. This is because a person who refuses to pay for a public good can not be kept from using it. Suppose that the neighbors in a high crime area decide to hire a police force. Each neighbor, except Mrs. Smith, agrees to pay $100 a year for it. Mrs. Smith refuses to pay because she knows that if all the others pay the $100, the police will guard the area anyway. So Mrs. Smith can enjoy the services of the police force without paying $100. The market system has no way to deal with this type of problem. For this reason, we can not ask each person to make a direct payment in the form. of product price. Therefore, we collect money for public goods by using taxes.

According to the passage, public goods are______.

A．services enjoyed by all people

B．what we can buy and sell in public

C．products that we make for national defense

D．taxes paid by the people involved

（阅读理解题)How often do you talk with people and notice that their words say one th

ing while

their action says another？ A facial expression, crossed arms or the way they behave can show what

is really in their mind. This is body language, and we must teach our children to understand and

use it.

them to be thoughtful in their body language. Giving examples is one of the ways to do that. Help

looking when they speak, how they turn their bodies, how they place their arms and so on can give

others important information.

situations, understanding body language can make a difference. And using body language in other

, such as trying to devise a better way to measure attitudes toward music or looking for a better way to teach mathematics.
