请帮忙看一下这几句话写的对么？谢谢

第一句问题在于缺主语 （make没有主语），单词用错了（import意思是进口，正确的为 important才是“重要的”意思和感叹句句式结构用错。这句话正确翻译有多种，提供一个参考答案，如下：
His failing at this test makes him realise how important going over lessons reguarly is .
第二句 也有错误可改为:Please don't forget what your parents tell you when you are leaving home.
第三句 是qingelis 中国式英语 不好 可以改为 I'm sure that her English knowledge is adequate to do this job well.
第四句有 三处明显的错误 首先连用了两个动词 （is 和 tell )其次用错了所有格 然后单复数用错 这句可以改为 The purpose of this article / This artical's purpose is telling students how to develop good study hobbies.
本人为英语专业学生，很乐意帮助你

1他这次考试失败使他意识到定期复习功课是多么重要。

good habits 好习惯
