问题补充：

I want to thank my friend John, without help, I wouldn have been saved.

A. his

B. whose

C. whom

D. Which

答案：

A. his

(答案→)B. whose

C. whom

D. Which

解析：句意：我想谢谢我的朋友约翰，没有他的帮助，我就不会得救。这是一个复合句，不是并列句，如果有and 在without前，答案就选A。without前没有并列连词，则判断without引导的是非限制性定语从句，引导词修饰help作从句中的定语，所以只能选whose意为......的。故选B。

考点: 考查定语从句关系词的用法。
