· 原因状语从句

· 结果状语从句
如果我们用从句来表达一件事情或一个行为发生的原因、目的或结果,那么这个从句就叫原因、目的或结果状语从句。例如:
(1) She’s my hero because she’s one of the best table tennis players in the world. 她是我心 目中的英雄,因为她是世界上最优秀的乒乓球运动员之一。
(2) ... and wrote books so that they could learn about how he treated the sick. ……并且著书 让他们(当地的医生和护士)了解他是如何医治病人的。
(3) At that time, there were few doctors, so he had to work very hard on his own. 那时医生 很少,所以他不得不很辛苦地独自工作。
句 (1) 中 because 引导的状语从句表示原因,句 (2) 中 so that 引导的状语从句表示目的, 句 (3) 中 so 引导的状语从句表示结果。
