the workers did all ___good care of the old man

题目

the workers did all ___good care of the old man
a they could to take b they could take c which they could to take d what they could to take
选什么 考什么语法呀

答案

应该选a
这是个定语从句的句子
all是先行词 后面应该跟关系词 that 由于that这个关系词在定语从句中担当宾语成分,所以它可以省略.本题就给省略掉了,
the workers did all they could 应该翻译成：工人们做了所有他们所能做的
to take good care of the old man 这个动词不定式来表目的
整句翻译如下：工人们做了所有他们所能做的来照顾那个老人
the workers 是句子的主语 did是谓语 all是宾语 （that）they could是定语从句 to后面的是宾补.希望这样解释你能看懂.
