Writing About English

Once, during an English exam, I figured it out that sometimes guessing the answer is so much easier and faster than trying to actually figure out the question by using my tiny brain. Anyway, I accidently found this website, and it has brought me back to a day when I'm learning English again. It feels so bad that after so many years,  I'm still stuck at the beginning level.

Regardless, it's time to open the English book once again, study, and never give up! 

By the way, if you need help with learning Chinese, may be I can help!

Good job! And welcome back! That's the right attitude! My friend, please do not think of yourself that way, you do not have a small brain. You know Chinese and some English, but I only know English (and poorly at that!), so what does that make me? While it could be better, your writing is at an acceptable level and you are able to clearly express your ideas, so just build upon that by learning more vocabulary. It is a process, you will learn at your own pace, so do not compare yourself to others. I will be glad to help you whenever and however I can, and I am sure that others here on iTalki will help you too!  J.
