I found that it will be a good way to practice, if write a same essay. Yesterday,  I wrote the essay about weather forcast which spent my 40 minutes. But toady I just used 15 minutes, and memorized the new words what I did't know yesterday.

77 is a lucky number, yet really I don't know what I can write. I have written them what I can  write.
