短文改错
Dear editor，
I am a high school student. A few days before，one of my very good friend told me that he was going to stop school. He said that he wanted to start his own business. I tried my best to get him change his mind, but failed. I know it is difficult of him to change his mind. He is not doing so good in his studies, yet I want to insist that I give it a try. The process is important than the results. Now there are only 90 days leaving before the test. I am not sure that his decision is right or wrong. I needed your advice.before改为ago

(答案→)before改为ago 解析：【小题1】before改为ago，a few days ago和过去时连用【小题2】one of后面用名词复数 friend改为friends【小题3】词组get sb to do sth让某人做…【小题4】句型：It is +adj +for/of sb to do…,如果adj是修饰事情，用for，如果adj是修饰人，用of，这题difficult是修饰事情，用for【小题5】副词well修饰doing，good 改为well【小题6】用he代替one of my very good friend【小题7】和than连用用比较级【小题8】left是过去分词做定语【小题9】I am not sure 后面接whether引导宾语从句【小题10】这句话是一般现在时needed改成need

感谢回答，我学习了
