 阅读理解DResearchers at the University of Arizona have been studying the effects of green light therapy on those suffering from migraine (偏头痛). In September, they completed their first clinical study and the results are very encouraging. They found that green light therapy is extremely beneficial to those who suffer from headaches. It not only reduces the intensity of the pain, but it also decreases its frequency by 60 percent, significantly improving patients' quality of life.According to the Migraine Research Foundation, migraine is the third most common illness in the world, affecting one billion worldwide, including men, women, and children. Additionally, it is the sixth most disabling illness in the world and more than 90 percent of the sufferers are unable to carry on with their normal activities during their sufferings. And when it is actually treated, medication overuse can lead to episodic (偶尔发生的) migraine turning chronic (慢性的).According to Science Daily, the recent clinical study included 29 patients who suffer from episodic or chronic migraine. They have tried but failed in several traditional therapies including Botox injections and oral medications. In the study, participants spent two hours at home each day staring at a green-light LED. They did this for ten weeks, reporting the number and intensity of headaches they had.Dr. Patwardhan, co-author of the study, said that the green light discharged by the LED greatly helps those who do not want to take medicine as well as those who do not respond to medications. "The beauty of this approach is the lack of associated side effects," Patwardhan explained. But that's not all. The participants also reported significant improvements in sleep quality and in the ability to perform everyday normal activities such as exercise and work. And none of them reported any side effects.As the study reveals, green light treatment might be an unprecedented (前所未有的) alternative for migraine sufferers. （1） What can we learn from the research? A . Migraine sufferers unable to live a normal life makes up about 60%. B . Episodic migraine can be treated more easily than chronic migraine. C . Headaches can be relieved by green light. D . Migraine most frequently happens to adults. （2） What were the 29 participants asked to do in the study? A . Take some traditional medicine daily for ten weeks. B . Use a green-light LED the whole night at home for ten days. C . Receive an injection each day for two months. D . Look at the green light for two hours per day for 70 days. （3） Which of the following can replace the underlined word "discharged" in Paragraph 4 ? A . lit up B . put out C . taken in D . sent out （4） What was Patwardhan's attitude to the new treatment? A . He thought it had side effects. B . He agreed it was of great benefit. C . He worried it might affect sleep. D . He wondered if it hurt eyes. 答案： C D D B
