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.

One example is New York University in Manhattan. The School of Continuing and Professional Studies began online classes in nineteen ninety-two. Its Virtual College has taught more than ten thousand students from across the United States and other countries. Last year, the School of Continuing and Professional Studies launched NYU Online. It offers NYU's first online programs to earn a bachelor's degree. Programs are offered in three areas: leadership and management, information systems management and social sciences. University officials say classes are highly interactive, where students communicate with each other and their teachers. Some classes require students to all log in at the same time so they can attend live lectures by a professor. Students can also ask questions and work together on team projects. The university says classes are taught by NYU professors who have been trained in online teaching. International students must take two admission tests before they can be accepted into the program. These are the SAT and the TOEFL. We will discuss these tests later in our series. The cost to attend NYU Online depends on how many classes a student takes. It can cost as much as fifteen thousand dollars a year. NYU offers no financial aid for international students in this program. You can get more details at nyu.edu. 1.
