The health-care economy is filled with unusual and even unique economic relationships. One of the least understood involves the peculiar roles of producer or “provider” and purchaser or “consumer” in the typical doctor-patient relationship. In most sectors of the economy, it is the seller who attempts to attract a potential buyer with various appealing factors of price, quality, and use, and it is the buyer who makes the decision. Such condition, however, is not common in most of the health-care industry.

In the health-care industry, the doctor-patient relationship is the mirror image of the ordinary relationship between producer and consumer. Once an individual has chosen to see a physician — and even then there may be no real choice — it is the physician who usually makes all significant purchasing decisions: whether the patient should return “next Wednesday”, whether X-rays are needed, whether drugs should be prescribed, etc. It is rare that a patient will challenge such professional decisions or raise in advance questions about price, especially when the disease is regarded as serious.

This is particularly significant in relation to hospital care. The physician must certify the need for hospitalization, determine what procedures will be performed, and announce when the patient may be discharged. The patient may be consulted about some of the decisions, but in general it is the doctor's judgments that are final. Little wonder then that in the eye of the hospital it is the physician who is the real “consumer”. As a consequence, the medical staff represents the “power center” in hospital policy and decision-making, not the administration.

Although usually there are in this situation four identifiable participants— the physician, the hospital, the patient, and the payer (generally an insurance carrier or government) — the physician makes the essential decisions for all of them. The hospital becomes an extension of the physician; the payer generally meets most of the bills generated by the physician/hospital, and for the most part the patient plays a passive role. We estimate that about 75-80 percent of health-care choices are determined by physicians, not patients. For this reason, the economy directed at patients or the general is relatively ineffective.

    Mr. Jackson was tired of living in his old house in the countryside and wanted to sell it and buy a better one. He tried to sell it for a long time, but was not successful, so at last he decided to go to an estate agent（房产经纪人）.

    The agent advertised the house straight away, and a few days later, the owner saw a very beautiful photograph of his house, with a wonderful description of his garden in an expensive magazine.

    Having read the advertisement through, the house owner hurried to phone the estate agent, saying, “I'm sorry, Mr. Jones, but I've decided not to sell my house after all.” “Why?” the agent asked in a surprised voice. “Because from the advertisement in that magazine I can see it's just the kind of house I've wanted to live in all my life.”

    It's common for children to grow up being told to minimize daydreaming, and instead to focus on lessons and class work. Historically, daydreaming students who go off on their own thoughts, rather than focusing on the teachers, the blackboard, or their class work, are often encouraged to stop allowing their attention to wander and to bring themselves back into the present moment. They're described as uninterested in school work and their future. Traditionally, daydreaming is seen as a practice that results in bad consequences.

    But recent studies are beginning to renounce those common beliefs by pointing out the potential benefits that daydreaming may provide. PsychCentral reports that Mary Smith, a psychological scientist and researcher, recently examined scientific writings and studies to gain a better understanding of the role of a reflective brain. These studies have shown that the brain has a network that is active when a person is daydreaming and that brain network can help memory and learning.

    Though paying attention in school is important, these results suggest that there should be time for students to daydream, too. Giving them the chance to reflect and daydream can help improve learning and development. Research also indicates that when students are permitted to daydream, they experience less anxiety and become more motivated. On the other hand, if students are warned against daydreaming, their knowledge of themselves and the world around them may suffer.

    As a result, educators are encouraged to promote a balance between outward and inward attention. A little bit of daydreaming to break up the hard focus on school activities can be beneficial, and it may help students become better, active learners.

    As for students, the lesson here is not to be afraid of doing some daydreaming. Sure, you want to pay attention to the vital information conveyed to you during your classes, but don't get discouraged if your mind wanders. A little bit of daydreaming is healthy.

    These days, North Kickapoo Street in Shawnee, Oklahoma, is a four-lane road leading out to the highway, and lined with all kinds of places to eat and shop. But in the mid-1950s, it was just a gravel(砂砾) country road, the perfect place for our daddies to teach us how to drive.

We didn't have driver's education at Shawnee High School. We were on our own. Mom took me to pick up an instruction handbook. I was the oldest of my friends, so we were excited at the prospect of a whole new world opening up. We'd have freedom to get around. Best of all, we could go to the Starlite Drive—In theater on 50-cents-a-carload night. We'd have it made.

    Mom let me back our 1949 Ford out of the garage a few times to get used to the clutch (离合器) and gearshift (变速排挡杆). I got familiar with the motion but was hardly ready for my road test.

    Finally, the day came for Daddy to give me a real lesson. He drove out to the end of the paved section of Kickapoo Street and across to where the gravel started. My daddy had come from a family of 10, and they had been farmers in a poor area in Oklahoma. There was only one way to do things, and that was the right way.

Praises were rare, so when he expressed his approval it was special. I didn't want to experience his glare if I ground the clutch or the car shook as I tried to get it going.

    I took a deep breath, slowly let out the clutch, pushed the stick into second gear, eased down the road, and then carefully moved into third gear. He had me stop and repeat the procedure two or three more times until I came to the end of the section. I was feeling pretty good as I came to a stop and looked to Daddy for approval.

He glared at me and then barked, “You've been driving, haven't you?” He must have thought I'd been practicing in somebody else's car. I quickly explained that my training was all done on the Ford.

    That was 60 years ago. I can still see the nod he gave me when he said, "Well, you did a good job."

    The Japanese have always been at the forefront at deploying (利用) robots to perform jobs that are traditionally done by humans. Over the past year, humanoid robots have been seen helping customers at the Mitsubishi Bank and even filling in for human science communicators at museums. Therefore, it is not surprising to hear that the country has the world's first hotel that is staffed almost entirely by the Androids!

    The aptly (巧妙地) named Henn-na ("strange" in Japanese) Hotel which opened its doors on July 17 is located at Nagasaki's Huis Ten Bosch theme park. It is the idea of Hideo Sawada, a Japanese businessman who is fascinated by the possibility of replacing humans with robots. His aim is to have this futuristic hotel be run mainly by the intelligent humanoids.

    Guests checking-in are welcomed by a family friendly English-speaking robot wearing a bow tie and bell-hop (侍者) hat. Though experienced at his job, he does request guests not to ask him "a difficult question" since he is after all, "just a robot!" Those seeking a more "regular" experience, can approach the human-like Japanese-speaking robot.

    When ready, visitors can request the robot "porters" to help carry belongings to their room. Those that need to stow away valuables can hand them to a helpful robot who will place them inside an individual safe box in exchange for a small fee. A one-foot-high concierge (管理人) is available to provide information about the hotel's amenities (便利设施), nearby attractions, and even order a taxi if needed.

    So how much does it cost to live in this crazy cool hotel? It depends on when you decide to go. During the low season, guests can get away with paying as little $60 a night for a basic room. However, during the peak season when rates, are determined by an online auction, the price can get as high as $153.

    Have you ever considered all the English expressions that include words about clothes? Let's have a look.

    People wear pants to cover the lower part of their bodies. We sometimes say that people who are nervous have ants (蚂蚁) in their pants. Sometimes, people may get caught with their pants down. They are found doing something they should not be doing. And, in every family, one person takes control. Sometimes a wife tells her husband what to do. Then we say she wears the pants in the family.

    Pants usually have pockets to hold things. Money that is likely to be spent quickly can burn a hole in your pocket. Sometimes you need a belt to hold up your pants. If you have less money than usual, you may have to tighten your belt.

    I always praise people who can save their money and not spend too much. I really take my hat off to them. Yet, when it comes to my own money, I spend it at the drop of a hat, which means I instantly spend it.

    Boots are a heavy or strong kind of shoes. People who are too big for their boots think they are more important than they really are. I dislike such people. My father is an important person. He runs a big company. He wears a suit and tie, and a shirt with sleeves (衣袖) that cover his arms. Some people who do not know him well think he is too serious and never shows his feelings openly. But I know that my father wears his heart on his sleeve.
