问题描述:

Promise to do 和Promise sb to do 区别何在
含义

Promise to do 答应做某事
Promise sb to do 答应某人做某事

当promise做“答应,允诺”的意思的时候,两者并无区别,只是Promise sb to do 中答应的对象更具体一些.
如:
I promised to attend to the matter promptly.我答应立即处理这件事.
I promised him to attend to the matter promptly.我答应他立即处理这件事.
当promise做“有……的可能”的意思的时候,仅运用于Promise to do 这一短语.
如:
This year promises to be another good one for harvests.今年可能又是个丰收年.
