你的理解是对的.
is 后面,或者用动名词,或者用不定式.
你举的例子,是非正式的语法.
口语里这么说,大家都可以理解.但是,书面语言,不行.

What you can do is (that) look at the fact.这个是be动词后的表语从句,可以省略that.后面的look at the fact的主语是you,就相当于祈使句了,所以不用looking.再说ing形式是指动作正在发生或有了谓语的情况下又出现动词,并且该动词与主语是主动关系的,这样才用ing形式。比如:He is watching photos now,th...

谁能解释下 What you can do is 后面跟动词为什么是原形,例如what you can do is look at the fact
以上是关于省略动词不定式做表语用法:主语,如果主语从句谓语部分出现DO 的形式时,做表语的动词不定式必须要省略TO 的,如果省略TO 就是动词原形了

例如:what you can do is (to )look at t...

例如:what you can do is (to )look at the fact (动词不定式做表语,由于TO 需要省略,因此就是动词原形了,
备注:如果不定式做表语,前面的主语谓语部分没有DO 形式出现,则不定式做表语的TO 一定不能省略,例如 What the boss wants to say is to give an increase to his employees' salaries

希望你能明白,谢谢!
