首先将以下句子改写成被动语态，并且告诉我例句是什么时态，为什么要在has和动词deliver之间加to.
He has to deliver the letter by hand.
He has to deliver the letter by hand.
have to是情态动词,相当于can,must这样的助动词,意思是不得不,被动应为the letter has to be delivered by hand
has to一起才是情态动词 表示不得不 后面接动词原型
被动语态是
The letter has to be delivered by him by hand
has to是不得不的意思
The letter has to be deliered by hand.
has/have to 不得不
