帮我看一下这几句话中有没有语法错误，谢谢了
1、Sometimes we may receive cases,which seem more interesting than dangerous. 2、Though it had past for years,i coulad still remember what happened that day clealy. 3、It were happened yesterday.(它就好象发生在昨天）It was at that time when i just started my dreaming life as a decetive.
全都有一些错误。 1、Sometimes we may receive cases,which seem more interesting than dangerous。 应该改为：1、Sometimes we may receive cases, which seem more interesting than dangerous。
[少空了一个] 2、Though it had past for years,i coulad still remember what happened that day clealy。 应该改为：2、Though it had past for years, I could still remember what happened that day clealy。
3、It were happened yesterday。(它就好象发生在昨天）It was at that time when i just started my dreaming life as a decetive。 应该改为：It happened yesterday。
(它就好象发生在昨天）It was at that time when i just started my dreaming life as a decetive。 我的开会了，没空看了，可能还有错误。 。
