should有時表示應當做或發生的事，例如：
We should help each other.我們應當互相幫助。

1. 用于表示“應該”或“不應該”的概念。此時常指長輩教導或責備晚輩。例如：
You should be here with clean hands. 你應該把手洗干凈了再來。
2. 用于提出意見勸導別人。例如：
You should go to the doctor if you feel ill. 如果你感覺不舒服，你最好去看醫生。

What is your father's job?
Which 指代的是特定范圍內的某一個人。如：
---Which is Peter? 哪個是皮特？
---The boy behind Mary. 瑪麗背后的那個男孩。
2. What...?是泛指，所指的事物沒有范圍的限制；而 Which...?是特指，所指的事物有范圍的限制。如：
What 買粉絲lor do you like best? （所有顏色）
你最喜愛什么顏色？
Which 買粉絲lor do you like best, blue, green or yellow? （有特定的范圍）
你最喜愛哪一種顏色？
