One possible version：  Li Ming likes basketball very much. He spends much time playing basketball and reading magazines about it. He studies hard but isn't good at English. His parents are looking for an English teacher to help him with his English.  I think it's not necessary for him to have another English teacher because he can get enough help from his English teacher at school. And his parents needn't pay extra money for that. I think he should spend less time on basketball and spend more time on learning English. What's more he should use every opportunity to ask his English teacher for help at school. (I think it's good for Li Ming to have another English teacher，because he will improve his English more quickly. And it's also a good chance for him to practise oral English.)
