Whether you are a working professional interested in doing all you can to stay mentally sharp, there are lots of things which you can do to improve your memory and mental performance.
请问老师,in doing all you can为什么后面没有do,这样定语从句不是缺少谓语动词吗?
do all / everything / what + 主语 + can (do) to do ... 这种句型中, (do) 通常是省略的,后面的 to do 是动词不定式作目的状语。
