On Feb 8,2008,I walked in a park,witnessing an elder’s being knocked down.(2008年2月8日,我在公园里散步,目击一位老人被撞倒.)
The registration number of the hit-and-run car I had seen is AC864.（肇事后逃逸的那辆车车牌号我看到是AC864.）
And then I took the elder to a hospital.（然后我将老人送往医院.）
Now he has recovered from injuries sustained in the accident.(老人在车祸中受的伤现在已痊愈.)
What’s more,he has got a certain amount of compensation from the troublemaker due to my reporting the case to the police.(而且,由于我的报案,老人从肇事者处获得一定赔偿.)
He thanks me very much.(他非常感谢我.)
