有读者问这样一句话：
(1)She did not want to have to dodge the caravan continuously.
请解释一下not want to have to，尤其是have to。
这里的have to有点特殊，与其作为情态动词的一般用法（即“情态动词+动词原形”）有所不同。但其本义仍旧是“必须，不得不”。“She did not want to have to dodge...”的意思是： “她不愿意非躲避……不可。”请注意have to不但可用于not want之后，也可用于其他表“不喜欢”等的动词之后，例如：
(2)I should not like to have to kill you.
(3)I hate to have to get up in the morning.
注意下面一句中的having to代替了to have to:
(4)I loathe having to tell you this but...
have to还可用于形容词之后，例如：
(5)— Did you know my father, Dan Murphy?
— He wasn't much, missus, I'm sorry to have to say.
have to也常用在be going to之后，但be going to have to则只意味着“将不得不”，例如：
(6)I'm going to have to eat something soon.
(7)Now you're going to have to hurry, because...
(8)This is a revolution! We're going to have to offend somebody.
