主谓一致有三种情况：

　　语法一致即单数名词与动词单数形式一致,复数名词与动词复数形式一致
　　就近一致只适用于 there be 句型；or/nor 和 not only …but also 连接的主语
　　概念一致即表示单数概念的名词与动词单数形式一致,表示复数概念的名词与动词复数形式一致.

不定代词 all 表示两种概念：指代“全体人”是复数概念,指代“所有事情/一切事物”是单数概念.另如：

All are equal before the law.法律面前,人人平等.（all指代人）
All is not gold that glitters.[谚]闪光的未必都是金子.（all指代事物）

本题就属于概念一致.句中的all I have to do指的是“我必须做的所有事情”,属于单数概念,因此要求用 is 与主语保持一致.

顺便说一句,不定式作表语,省略 to 属于非正式英语,在正式英语中to则不省略.因此,这个句子的正式说法是：all I have to do is (to) take deep breaths（我必须做的一切是作几下深呼吸）
