I must have slept right through it.Later on it will be a lot tougher for you.
第一、I must have slept right through it.
这里的must是情态动词,语法书上说情态动词后接动词原形,这里的must后面跟的是完成时态have slept,可以这样用的吗?我第一次见情态动词后接完成时态.
第二、Later on it will be a lot tougher for you.
这里的tough为什么要加er?
a lot tougher是一种什么用法?

must have done 这种表达方式在情态动词中非常常见,一般表示一种虚拟的或对过去的推测用法,本句的意思就是“一定已经”,表示对过去的肯定推测,而must do表示现在或将来
2 就是比较啊,“比以前更加艰难”,a lot用于前面表示程度
第一,must have done 表猜测,已非情态动词。意思为:一定已经。
第二,tougher用比较级,有will,是说这件事情你以后做要比现在做更难。a lot 意思同much,修饰比较级程度。难得多
