重点词组（词）的辨析：
1. have to /must 不得不，必须
have to 强调客观，must强调主观。例：
Mother is ill. I have to look after her.
I must study hard.
have to有时态、人称变化，否定问句结构用助动词。
have to → don't have to
has to → doesn't have to
had to → didn't have to

must的否定式有mustn't和needn't，must只有一般现在时，needn't常作否定回答。

No, you needn't . 不，不必。
