我写了一篇英语作文,My View on FriendsReal friends share the same idea

修改如下：（删去括号内的内容即是修改好的全文）
Real friends share （the same 删掉,既然share,说明不一样,分享）ideals and interests.My friends are very kind.We help each other and make progress (advance 删掉,不好）together.If I make a mistake,they （my friend 重复） will not hesitate to point it out for me.We often play basketball together(outside 不必点明室外,没有意义）.One of my friends （前面friends是复数,这里应点明是一个朋友）is good at English,but I am poor at (固定搭配,不用in)it.With her help,(When I had difficulties,my friend can help me.So 罗嗦,删去)my English has （had 不要,不用过去完成时）improved a lot.I think maintaining (keep 不好,而且作主语要用ing形式）friendship is very necessary.I like my friends.

楼主的文章总的来说是没什么大问题，语法上也是对的，但是我觉得，句子和句子之间是不是用上些and,besides,so这样的连词或者连接性短语会比较好，显得文章比较有条理，不会像无数个句子堆在一起。呵呵，这是我的意见，请参考一下，希望能帮到你...

首句改为 Real friend have the same ideal and interest

基本GOOD！
把后半部分的friend单数改成复数，与前文保持一致。
So my English had improved改成：So I improved my English a lot.
I think keep friendship is very necessary改成：I think its necessary to keep friendships.

So my English had improved a lot.
是不是应该改成have improved a lot
I think keep friendship is very necessary
I think keeping friendship is very necessary.
