请各位英语高手帮我看一下这篇文章的语法错误,并指出以便改正

Life的复数 是 lives。我想做这样的人是：i want to be people like that。musy 写错 must hard 就可以了,或者用 more hard,harder 不对。because I think 改成 ifhave a good body 是中国的表达方式,应该改成：keep fit。感冒是 catch a cold。吃药用 take 不用 eat how to ,how 写错了like eat much more vegetables 不用like ,用 such as 或 for examplethose 改成 thatbeside是旁边的意思,身边的人应该用 everybody around me好可爱的小盆友啊,加油,写的不错 再给你补一篇好一些的,你拿去看一看,My Dream JobI want to be a doctor when I grow up,just like Mom and Dad。In my opinion,doctor is a great job,because doctor can save many people's lives。I want to be people like that。To be a good doctor,I must study hard at shcool firstly。Secondly,I should keep fit；I think a docotor who want to make his patiens healthy should be healthy of himself。But these are still not enough。I should learn about illness,too。For exampel,When I catch a cold,what medicine should I take?Further,I 'll go to hospital to learn about looking after patients。What's more,I'm planing going to learn hou to keep fit,such as eating much more vegetables etc,and tell it to my parents and friends。If I know that,I would be able to take care of my friends and my parents。Everybody around me will be healthy。I hope illness will disappear in the world,everybody will be healthy and happy everyday!
