Today I was having a PE lesson while I fell down and hurted my foot. I was in great pain at that moment, but I tried to act as if nothing had happened until the class is over. Though I had difficulty walk back to my classroom, but I still didn’t tell anyone and even refused the offer of help from my classmate. As the result, the hurt in my foot became worse. Now I know I was wrong. We can tell other our need for help and accept their help. Someday we can help him in return. In this way, we can get along with each other happy and peacefully.while改为when
网友回答
(答案→)while改为when
解析：
【小题1】while改为when 连词while后面的谓语动词要使用延续性动词，本句后面的动词fall down是一个短暂性动词，故使用when来连接。
【小题2】hurt改为hurted 本句中的动词hurt的过去式和过去分词和原形是一样的。
【小题3】is改为was 本文是一般过去时为主的，故使用一般过去式的时态。
【小题4】walk改为walking 固定搭配have some difficulty doing sth做某事有困难。
【小题5】去掉but 连词though不能与but连用。
【小题6】classmate改为classmates 这里是指多个同学classmates.
【小题7】the改为a 固定搭配as a result结果是。
【小题8】other改为others 这里的others是名词其他人，指告诉其他人我们的要求。
【小题9】him改为them 这里的them是指上句的others，故使用复数形式。
【小题10】happy改为happily 本句中的副词happily做状语修饰动词短语get along with each other
