Though night is deep,but I don't want to go to bed now,because of lacking drowsiness.The day before yesterday,I wrote a short blog about the CET-6. going beyond my expectation is that it received six replies.some friends ardently pointed out the fauses in my blog,some other kind guys encouraged me by warm words such as"good lunk""success waiting for you",etc.All in all, it is necessary to show my sincere thanks and to keep writing english blog.
