版上各位先进您好, 小弟不才, 刚刚担任家教时
看到一题文法题却无法很确定地回答学生
题目是这样的:
He always does ________ he thinks is right.
a.who b.what c.whose d. which
我觉得(心虚)答案可能是 b , 但又潜意识地觉得可能是d
但却又无法斩钉截铁地说出所以然, 盼望指点迷津 , 感激万分!!:)

b

what才同时有先行词和关系代名词的性质

b

b

He always does the thing which he thinks is right.what=the thing which

b 他认为是对的事情what

what是复合关系代名词, 包含先行词the thing和which关代
