The Wal-Mart in Cleburne, Texas, was crowded. People were waiting in long lines at checkout counters to pay for small things that would be next-morning treasures under someone’s Christmas tree.

       The woman standing in cashier Jeffrey Kandt’s line seemed to be living on the edge of subsistence（生计）. Her clothes were worn and her hands were those of a person who’d worked hard for what she had. She held a single item in her arms as she patiently waited to move to the front of the line — a Sony CD player. She had saved all year for this. With tax, the total would be close to $ 220.

       As the woman got close to the cashier, she suddenly shouted, “Where’s my money? All of my money fro my son’s gift! Oh no!”

       “Why my line?” Kandt thought as he watched the poor woman searching through her clothes. He was going to have to call his manager to avoid the sale but it would mean a long wait for the customers behind her. “I am going to go home late tonight,” Kandt thought.

       Then an amazing thing happened. At the back of the line, a man took out his wallet, pulled out $100 and passed it forward. As the cash moved up the line, a twen5ty-dollar bill was added here, and a ten-dollar bill was added there. When the collection finally reached the registewr, Kandt counted $ 220.

In cities with rent control, the city government sets the maximum(highest) rent that a landlord can charge for an apartment. Supporters of rent control argue that it protects people who are living in apartments. Their rent cannot increase; therefore, they are not in danger of losing their homes. However, the critics say that after a long time, rent control may have negative effects. Landlords know that they cannot increase their profits. Therefore, they invest in other businesses where they can increase their profits(利润). They do not invest（投资） in new buildings which would also be rent—controlled. As a result, new apartments are not built. Many people who need apartments cannot find any. According to the critics, the result of rent control is a shortage of apartments in the city.

Some theorists argue that the minimum（lowest） wage law can cause problems in the same way. The federal（联邦） government sets the minimum that an employer must pay workers. The minimum helps people who generally look for unskilled, low—paying jobs. However, if the minimum is high, employers may hire fewer workers. They will replace workers with machinery. Therefore, other things being equal, the number of workers that employers want decreases. Thus, critics claim, an increase in the minimum wage may cause unemployment. Some poor people may find themselves without jobs instead of with jobs at the minimum wage.

Supporters of the minimum wage say that it helps people keep their dignity. Because of the law, workers cannot sell their services for less than the minimum. Furthermore, employers cannot force workers to accept jobs at unfair wages.

Economic theory predicts the results of economic decisions such as decisions about farm production, rent control, and the minimum wage. The predictions may be correct only if “other things are equal”. Economists do not agree on some of the predictions. They also do not agree on the value of different decisions. Some economists support a particular decision while others criticize it. Economists do agree, however, that there are no simple answers to economic questions.

There is the possibility that setting maximum rent may           .

         A．cause a shortage of apartments

         B．worry those who rent apartments as homes

         C．increase the profits of landlords

According to the critics, rent control             .

         A．will always benefit those who rent apartments

         B．is totally unnecessary

         C．will eventually bring negative effects

         D．is necessary at any time

Some theorists believe the problem of unemployment will arise           .

         A． if the minimum wage is set too high

         B． if the minimum wage is set too low

         C． if the workers are unskilled

         D． if the maximum wage is set

Which of the following statements is NOT true?

A．The results of economic decisions can not always be predicted.

         B．Minimum wage can not always protect employees.

         C．Economic theory can predict the results of economic decisions if other factors are not changing.

         D．Economic decisions should not be based on economic theory.

Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity(好奇). Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary(薪水) and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”

After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”

This began a set of questions that lasted nearly two hours.

Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and cre ative answers.

Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior(行为). But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.

Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target(目标) for your disagreement.

Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
