I find a watch on the road.根据问句写答句.

这个句子,不知道你是从那里看来的。如果是这样就符合英语习惯了：I found a watch on the road。即使这样,它的问句可能有两种情况：1。Did you find a watch on the road?回答是,yes,I found a watch on the road。'2。Did I find a watch on the road?Yes,I found a watch on the road。(这种不是生活情景,而是课堂情景。比如自问：Am I a teacher?Yes,I am a teacher)
