问题补充：
Yesterday morning I was going to school on our foot with Li Ming. 1.
We were talking and laughing happily on the way while a motor-bike 2.
knocked me off my bike. As a result, I seriously hurt in the left leg 3.
and could hardly stand up. Seen this, Li Ming jumped off his bike, put it 4.
aside, stopped a taxi and took me to the hospital at once. In the hospital, a 5.
doctor gave me quick examination. I was told that I had to stay there for 6.
some time. So Li Ming went out and ring up my parents. He told them what 7.
had happened to me in the street. He didn’t leave the hospital until his parents 8
arrived. I stayed in the hospital a whole day until later in the afternoon. 9.
Luckily, I can walk as better as before now. I must thank Li Ming for his help.10.1. our 去掉
答案：
(答案→)1. our 去掉
解析：
1.因为on foot 是固定词组“步行”
2.这里是be doing…when 固定结构，表示“正在做某事时另外一件事情发生了”
3.这里应该是被动语态“be hurt ” “受伤”
4. seeing 的逻辑主语就是主句的主语Li Ming
5.正确
6. examination是名词，所以前面要加a
7. and 并列句前后成分应该是一致的
8.这是一个逻辑性的错误
9. 这里表示时间用“for”
10. as…as 中间应该用原级，修饰walk 用副词well
