有不情愿,被迫之意。一、have to 与其他情态动词一样也是后接动词原形,表示外界的强制作用,强调被迫性。含有不情愿的色彩,常译为“必须,不得不”。二、have to 可用于多种时态,而且不同时态使用不同的形式:一般现在时中,主语为第三人称单数时用has to ; 一般过去时中,用 had to。 have to 还可以用在其他的情态动词之后。例如:I have to do some washing.我必须洗洗衣服。She has to look after her little sister.她不得不照顾她的小妹妹。三、have to 的否定式和疑问式一般要借用助动词do的适当形式构成。have to 的否定式是don’t have to; has to 的否定式是doesn’t have to; had to 的否定式是didn’t have to。have to的疑问式同样也借用助动词do的相应形式构成。例如:—Do I have to go there now?我现在就得去那儿吗?—Yes, you do. (No, you don’t have to.)是的,你必须去。(不,你不必。)
