问题补充：
It was 7:15 in the morning of February 8, . I was walking along Park Road towards the east while an old man came out of the park on the other sides of the street. Then I saw a yellow car drive up Third Street and made a right turn into Park Road. The next moment the car hit the man while she was crossing the road. He fell with a cry. The car didn’t stop and drive off at full speed heading west. I noticed the driver was young woman wore a pair of glasses and the plate number was AC864. After two minutes later, I stopped a passed car and took the old man to the nearest hospital.in改为on
答案：
(答案→)in改为on
解析：
【小题1】in改为on具体到某一天的早晨，可以使用on.
【小题2】while改为when when后面的从句中可以使用延续性动词也可以使用短暂性动词。While后面的从句只能使用延续性动词。这里的come out of…是一个短暂性动词。故使用when。
【小题3】sides改为side路的另外一边是单数形式side。
【小题4】made改为make这里的make a right turn与前面的drive up是并列关系。
【小题5】she改为he这里的he就是指前面的the man。
【小题6】drive改为drove这里的drove与前面的didn’t是一致的，都使用一般过去式。
【小题7】was后面接a后面的名词woman是可数名词，故使用a来修饰。
【小题8】wore前面加who；或者把wore改为wearing本句中使用定语从句或者现在分词做定语来修饰。
【小题9】去掉later前面的after two minutes在句中作时间状语。
【小题10】passed改为passing使用现在分词doing转换的形容词作定语，passing经过的。
