相同,作为形容词时,都可作表语
区别,sick可作定语,ill不能,如sick man ,the sick 而不是ill man ,the ill
但当ill作‘坏的’,‘恶劣’解时,则通常作为定语,不作表语,如,he had a ill name .

ought to和should的区别
1) should和ought to表示责任、建议或劝告,翻译为“应该”,后者语气强一些。
如:You should listen to the doctor's advice if you want to recover soon.
Such things ought not to be allowed.
2) should接动词的完成式,是一种谴责,表示过去应该做而没有做或过去做了而不应该做。
如:I missed the class. I should have come earlier.
I shouldn't have made such a foolish mistake.

sick 能作系动词 而ill不能
ought to 又完成时态 而should没又
