The treatment will continue until the patient reaches the point ( ) he can walk by himself.


A、

that


B、

where


C、

what


D、

which


【正确答案】:B
【题目解析】:

本题考查定语从句连接词的使用。
分析句子结构,先行词是point此处意为“阶段、时刻”,从句“he can walk by himself.他能自己行走”与“point阶段”之间需要介词at/on进行连接,此处没有介词,因此连接词需要使用关系副词where,故选B。
句意:治疗将一直持续到病人能自己行走为止。
