题目内容
The doctor did __________ save the patient’s life.
| A．that he could do | B．all what he could |
| C．all he could to | D．which he could |
C
解析试题分析：考查省略句和不定式做目的状语：句意：医生尽了最大努力救病人的生命。All是这句话的宾语，he could是定语从句修饰all，定语从句省略了关系代词和动词do，不定式这里是目的状语，选C。
考点：考查省略句和不定式做目的状语
点评：这是易错题，考生容易受经验影响，认为could后面接动词原形，这时要注意分析句子成分，将缺失的部分补全后，再结合句意判断。
