在我犯那些蠢错误之前，妈妈一直是非常信任我的。她认为我是一个诚实的孩子。可我再也不能拥有这份信任了。我真不该对她撒谎，我多么后悔呀!事情是这样的。有一次我数学考试不及格，可我骗妈妈说我考得不错。起初她相信了，可过了几天她从我老师口中知道了真相。从那以后我还犯过相似的愚蠢错误。妈妈曾经告诉我犯错是没什么的，重要的是能够承认错误并及时改正。我向她发誓一定改正我的坏行为。可妈妈似乎并不像以前那么相信我了。我多么希望妈妈再相信我呀!

         before i made those silly mistakes, mother trusted me all the time.she regarded me as an honest kid. but i could never own her trust any more. how i regretted having lied to her! here was one of the stupid mistakes i've made. i failed in a math exam, but i lied to mother that i got a good mark. she believed me at first, but several days later she got the truth from my teacher's mouth.  i made several similar mistakes since then. mother told me that it doesn't matter to make mistakes, but it is really important to admit and correct mistakes. i swore to correct my bad deeds.but it seems that mother will never trust me as before. how i wish mother could trust me again!
