宾语从句主句有can，从句动词要原型吗，

Question

比如本来要填makes，主句有了can就要用make？

Answer 1

从句动词的形式看从句的主语和时态,和主句是否有情态动词can没关系.本回答被提问者采纳

Answer 2

宾语从句怎么分清主句和从句？i
will
do
what
i
can
to
help
you.can后面为啥跟to？can
不是情态动词吗？
i
will
do
what
i
can
to
help
you
句子语法结构分析如下
主语：i
谓语：i
will
do
宾语从句：what
i
can
(do)
目的状语：to
help
you

Answer 3

因为can是情态动词，用在can后面的动词都用原形

Answer 4

你的问题不明确，因为没有具体的句子，例题。我的答案是不一定，
例如：We are certain that he has helped his mother with the housework as much as he can to reduce his mother's burden.
can在句中的位置很关键。
