One afternoon after I was on my way home，the weather changed suddenly．Dark clouds were gathered．I began to feel worried because I didn’t have both a raincoat or umbrella about me．It soon started to rain. Just as 1 was hurrying home, I heard of someone calling me from behind．I turn to have a look and found that he
was Liu Wei, a good neighbor of mine．He offered to share his umbrella with me．We walked all the ways home．With Liu Wei’s help, I would have got wet to the skin．How thankful 1 was to his help!after改为 when
网友回答
(答案→)after改为 when
解析：
【小题1】when引导时间状语从句，当…时候
【小题2】乌云在聚集是主动式：gathered改为 gathering
【小题3】后面是：a raincoat 说明不是两者都both，而是两者任何一个， either;
【小题4】umbrella是可数名词前加 an
【小题5】听见某人做什么：hear sb doing，去掉 of
【小题6】考查时态，这篇文章用过去时，turn 改为turned
【小题7】表示不确定的人用it，he改为 it
【小题8】all the way home回家的路上
【小题9】考查介词：意为：没有刘磊的帮助，我们就会湿透了。With改为 Without
【小题10】考查介词：be thankful for对…感激，to 改为 for
