英语翻译求别电脑翻译,因为电脑翻译木有过去式…会是会写,就是不会用时态…以下为翻译内容,要求用过去式（就是动词后加ed?

One day I was going to take a walk in park, I met two American guy。 They were watching their map but totally got no idea to get to bus station by walk。
So they called me when i passed them and asked me how to get there。 I said "Are you speak Chinese?" They answerd no。
Then i just show the way their by gestures but unfortunatly they couldn't understand me。 So i changed the other plan and explaned how to read station brand to him, they got it anyway。 After this i had stayed in the bus station untill they got into the right bus and said goodbye to me。
It was such a beautiful day to me。
