One day morning【删去day以避免重复,改为One morning】 after the snow ,I saw a woman riding a bike fall off on my way to school。She was very old and she couldn't get up by herself。So I came【改为went】 forward to her,helping【改为helped】 her to get up and asked for her telephone numbers of her workplace。Then I immediately call【改为called】 120 and her workplace to notify the situation。Before the arrival of the ambulance,I chatted【后面加with】 her and did a little first aid to help her stay active。Finally the ambulance came and the doctors moved her carefully into it。I said good bye to her and her smiling【改为she smiled】,I know【改为knew】 she appreciated what i did 。
What a wonderful experience I had。It felt good to help others。
