1.参考答案：D
参考解析：哪一个政府机构许可(approved)使用该类抗癌药?就是本段第一句提到的the Food and Drug Administration。四个选项中，只有关系代词which能指代the Food and Drug Administration．它是approved动作的发出者。
2.参考答案：A
参考解析：本段表达的意思是：由于癌症病人服用了卡培他滨后指纹何时开始消失还不清楚，所以主治医生要提前为病人开具指纹可能会消失的证明单。to take place(发生)之前填上like，decide或have都与上下文的意思接不上，唯有begin最合适。3.[不定向选择题]____________A.printed B.located C.cured D.placed
