The latest Dream managed an average speed of 89.76 km/h, compared to 84.96 km/h for the previous one, despite stormy winds and uphill slope slowing all the competitors during the event's second day. However, during the final day's run from the South Australian desert mining town of Coober Pedy to Adelaide, the Dream cruised(以发动机效率最高的速度行驶) at 100 km/h, occasionally accelerating to 110 km/h. "We are very tired and very happy," the Dream team's project leader, Masashi Kitagawa, told the crowd of reporters waiting at the finish line at Adelaid's Technology Park. The School of Biel team placed second, an hour and 28 minutes behind the Dream, having averaged 86 km/h. The Swiss engineering school is Honda's perennial rival(竞争对手) in this event, having beaten Honda in 1990 to set a course record of 38.50 hours. However, they placed a distant second to the Honda Dream in the 1993 event. A full report, along with pictures, will appear in the next issue of Honda: The Magazine.

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.
