i can speak english   情态动词是什么作用?

表达"能力". (体力、知识、技能、容量)

Can you lift this heavy box? (体力)

Mary can speak three languages.(知识)

Can you skate?(技能)

This hall can hold 500 people at least. (容量)

注:此时可用be able to代替。

No one is able to do it. (= No one can do it.)

区别: can(一般现在时)和could (一般过去式);而be able to通过be的变化则有更多的时态,它也可以用于不定式或与其他助动词或情态动词连用,can 或 could则不可。

I’m glad to be able to attend your wedding party.

She might be able to play the role.

I haven't been able to find any jobs.

can speak

这里是情态动词+动词原型构成谓语,译为“可以说”是有实意的,不是单纯的强调作用

表示你有做某事的能力。

我觉得应该是起强调作用
