have to 变被动语态
He have to deliver the letter by hands.
我觉得have to 是实义动词,所以说应该是：The letter is had to deliver by hands.
The letter had to be delivered by hands.WHY?
类似的还有：We have to cancelled the match.The match had to be cancelled.
He have to deliver the letter by hands.
我觉得have to 是实义动词,所以说应该是：The letter is had to deliver by hands.
The letter had to be delivered by hands.WHY?
类似的还有：We have to cancelled the match.The match had to be cancelled.
have to 属于具有情态动词特征的一类情态动词,并非实义动词
固定结构一定是：sb./sth have to do .
变为被动也不会出现is,一定是sb/sth have to be done
所以这句话根据以上规则应该变为答案所述,即：The letter had to be delivered by hands.
再问： 那么把The letter had to be delivered by hands 变成一般疑问句呢？是不是Does the letter have to be delivered by hands?但是如果have是情态动词，就该是：had the letter to be delivered by hands.哪一个对呢？
再答： 注意时态，应该是Did the letter have to be delivered by hands?这个是毋庸置疑的 但是它变成陈述句或是被动语态的时候一定是我上述形式 have to 只能说它具有情态动词的特征，我想纠正我上面提到的，严格地说，have to不是情态动词，只不过它后面也是加动词原形，为了方便理解，把它当作情态动词罢了，但它也并非是实义动词。 所以说，你记的时候把have to 的陈述、被动、疑问形式都记清楚了，做题就万变不离其宗了。 （PS：像need和dare to，既可以当情态动词，又可以当实义动词，当作为情态动词时，词形不变，而作为实义动词时，则会相应地改变词形。 ）
