短文改错 (共10小题；每小题1分，满分10分)
Today I was having a PE lesson while I fell down and hurt my foot．I was in great pain at that moment but I tried to act as if nothing happened until the class was over． Although I had difficulty walk back to my classroom, but I still didn't tell anyone and even refused the offer of help from my classmates． As the result, the hurt on my foot became worse．Now I know I am 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

(答案→)while改为when 解析：【小题1】while改为when 连词while后面只能接延续性动词，而本题后面的fall down是一个短暂性动词，故使用when。【小题2】nothin后面接had 虚拟语气，本句是对过去发生的事情进行描述，如果as if后面的内容是假的，就使用过去完成时的形式。【小题3】walk改为walking 固定句式have some difficulty doing sth做某事有困难。【小题4】去掉but 连词although不能和but连用。【小题5】the改为a 固定搭配as a result结果是。【小题6】on改为in 介词In指在脚上。【小题7】am改为was 本句是指我知道我过去所做的事情错了，故使用一般过去时。【小题8】other改为others 本题中的others指其他人，又没有范围限制，故使用others。【小题9】him改为them 这里的them是上句的others。【小题10】happy改为happily 本句副词happily与peacefully都做状语修饰谓语动词。

我明天再问问老师，叫他解释下这个问题
