Some people suggest for better roads, others for cars to be banned (禁止) from city centers and yet others say better public transport would attract drivers from their lonely and boring journeys. But the important question is what natural power creates a big city center. We are, after all, in an age of electronic communication; our big shopping areas have moved out of city centers, and our living areas moved out of them long ago. Yet some force causes offices and service industries related to them to gather in London or New York or Tokyo. This suggests that far from the problems of a crowded environment forcing companies and people to move out, there is a critical (重大的) size beyond which more companies are attracted to move in. Nobody seems to know why, yet the answer is important to the way traffic jam is dealt with. Which of the following is NOT mentioned in the passage as the cause of the traffic problem？ A．The poor public transport. B．The over-concentration of shopping centers. C．The great number of cars in the city centers. D．The bad road conditions.

A．To reduce the rate of babies born too early． B．To reduce the risk of low birth weight． C．To reduce fetal deaths in pregnant women infected with HIV． D．To increase the number of lymphocytes in mothers’b1ood．

Using placebos to test drugs sometimes has a surprising result. Researchers say people taking the placebo often report improvements in their health. This is known as "the placebo effect"--pain that is eased or stopped by an inactive substance. In such testing, the drug must perform. better than the placebo to prove that it is effective. Doctors have reported that the placebo effect can be used in treatment. For example, a doctor tells a patient that a new drug will stop the pain in his leg. The pill is only sugar. But the patient does not know that. He takes the pill and says his pain is gone. Scientists are beginning to discover some physical reasons for this reaction in some people. They are learning that much of what people believe to be true comes from what the brain expects is going to happen. If the brain believes a drug will ease pain, the brain may begin physical changes in the body that can cause the expected effect. A recent examination of studies on drugs for depression found that placebos eased the depression about as well as the active drugs. Other studies have explored the power of placebos. A study in Japan involved thirteen people who reacted to the poison ivy (常青藤)plant. Poison-ivy causes red itchy sores(伤痕)on some people who touch it. Each person was rubbed on one arm with a harmless leaf, but was told it was poison ivy. Each person was then touched on the other arm with poison ivy, but was told it was a harmless leaf. All thirteen people developed a reaction on the arm where the harmless leaf touched their skin. Only two reacted to the poison ivy leaves. Doctors and scientists worry that the use of placebos may not always be harmless. They say people can become victims of false doctors and others who use placebos to claim they can cure disease. What do medical researchers usually use to make placebo pills？ A．Ivy leaves. B．Harmless leaves. C．Medicine being tested. D．sugar.
