Hello everyone!

I have been learning English and now I can read many writing a lot of writing now.

这样比较自然。

But if when I write something, there are always a lot of mistakes in my english grammar...

“XX的时候”应该用“when”, “if”只有“如果”的意思。

Also, I can't follow someone,who speaks english someone speaking English too... 

“someone who speaks English"＝会英文的人

“someone speaking English"＝正在讲英文的人

It puzzles me. Who can give me some suggestions advice?

Thx...

Hello everyone!
I have been learning English and now, I can read many texts.
But, when I write something, there are always a lot of grammar mistakes, in addition, I can't follow someone when she/he speaks, it puzzles me. Can/could someone give me some advice?

Thanks.

What I suggest you to follow better a conversation is to listen to the radio and talk to yourself. Many people don't take it seriously but by talking to ourselves in our target language we increase our fluency a lot. Also, whenever you get a chance to speak with people who know English, do it, practice is important. Increase your vocabulary and read a lot. By reading you see the way people write, then, pay attention the grammar and copy the way people speak, imitate them!
