Picture a test paper handed back with nothing crossed out and nothing taken off — every point there is, all of them yours. That picture is where both uses start: one keeps it in the classroom, the other carries it out of the classroom and uses it to praise people.
可以想成一張發回來的考卷，上面一個紅叉都沒有，該拿的分全部拿到。這個畫面是兩個用法的共同起點。一個留在教室裡，就是字面上的滿分。另一個把這張想像中的滿分考卷帶出教室，用來稱讚別人：你做的這件事，我打不出扣分的地方。
