good

Very good

great and helpful

It is good.

for the last question "whether it is healthy to work at night" today , in my opinion, i dont think so, because in the long evolution of most of the living creatures ，night is a time when we should take a rest and sleep to give our body ，brain a relex rather than always working. seldom people are out of that, we all inherit gene from our parents. Anyway, night has its own advantages for working,quiet,easy to focus on things. but long time and keeping working in the night would not be a good idea no matter you like it or not. that would go against the rules of the nature and be unhealthy to a person's growing,metabolism,character,quality of skin and even his / her future children .

Thankful, I really going to miss my teacher.

I feel good,I have more confidence to improve my english leavel.

My poor English brought two more rounds of interviews by Apple's managers. They were not sure if I was the right person they were looking for, so they they asked two more interviewers to interview me. Because I cannot express what I think in correct and simple words always. So now I'm really eager to study english, how I hope I can speak English fluently like a native! Thanks a lot for your help in the past lessons, I hope I could do better these months.

I need practice pronounciation more.
