Kennedys Death　　Senator Edward Kennedy, a legendary political figure in the United States, died on Tuesday after a year long battle with malignant glioma, the most common type of brain cancer among adults. Although he had the most up-to-date treatments - surgery at Duke University Medical Center, chemotherapy and radiation - he was not able to survive the disease. Doctors still dont know what causes brain tumors and the National Cancer Institute says the outlook for patients with malignant gliomas is poor.　　Kennedy had whats called a craniotomy, which involves opening the skull to expose the surface of the brain. Surgeons then determine the exact location of the tumor, often with the help of an MRI or CT scan. During part of the procedure, patients can be brought back to consciousness. That helps the doctors avoid cutting in areas that control speech. The brain will not feel any pain, so you can stimulate while the patient is awake and test the motor function, the speech functions while the patient is awake which allows very accurate determination of where these eloquent areas of the brain are, Dr. Caputy explains.　　Doctors caution that even with treatment, these aggressive tumors always come back. Whats not known is when　　A.Senator Edward Kennedy died right after he had the tumor.　　C.Senator Edward Kennedy died because he didnt get up-to-date treatment.　　正确答案:D　　2.What is the experts attitude towards the outlook for patients with malignant gliomas　　B.Pessimistic.　　D.Not mentioned　　解析:问题问的是：专家对恶性神经胶质瘤患者的前景看法如何?第二段最后提到医生仍不清楚发病原因，国家肿瘤学会称恶性神经胶质瘤患者的前景并不乐观　　A.He had a surgery at Duke University Medical Center.　　C.He made a speech about craniotomy.　　正确答案:C　　4.Which statement is NOT true about the risk factors that cause brain tumors　　B.Kids are more likely to have brain tumors than adults.　　D.70-year-old or older people are more likely to have brain tumors than those under 70　　解析:问题问的是：以下关于可能引发脑癌的危险因素的论述哪一项是错误的?倒数第二段提到了ACD的说法，即男性比女性更容易患脑癌;白人更容易患脑癌;70岁以上的人更容易患脑癌。只有B小孩比成人更容易患脑癌没有提到。因此选B　　A.Experts have already figure out the exact cause of brain cancer.　　C.Patients usually remain sleeping during a craniotomy.　　正确答案:D
