同等学力英语语法复习之比较状语从句

     比较状语从句。首先大家必须搞清楚状语从句，从本质上讲，状语从句就是用连词将几个分句连接起来，用来表达分句之间特定的逻辑关系。来看一个例句：

　　【例句】George Annas, chair of the health law department at Boston University, maintains that, as long as a doctor prescribes a drug for a legitimate medical purpose, the doctor has done nothing illegal even if the patient uses the drug to hasten death. “It’s like surgery,” he says. “We don’t call those deaths homicides because the doctors didn’t intend to kill their patients, although they risked their death. If you’re a physician, you can risk your patients’ suicide as long as you don’t intend their suicide.”

　　【解析】句中共有6个连接词，即含有6个状语从句，其中as long as，if是引导条件状语从句;even if，although是引导让步状语从句;because引导原因状语从句。所以说，状语从句在长难句中的出现频率很高，需要特别重视学习。

　　【参考译文】波士顿大学健康法律系主任乔治·安纳斯认为，只要医生是出于合理的医疗目的开药，纵然服用此药后会加速病人的死亡，医生是无罪的。他说：“这就像做手术，我们不能把死亡称作谋杀，因为医生并没有想杀死病人，尽管他们冒着死亡的危险。如果你是一名医生，只要你没有想让病人自杀，你就能冒你的病人自杀的危险。”

 
    常用引导词：as（同级比较）， than（不同程度的比较）
