last summer holiday, i went to a private school to be an english teacher. the students were all very small, some of them only 9years old,while some of them were 14 years old. i taught them words, phrases and they were very diligent, lovely and intelligent. we got along with each other very well. at first i was a little bit nervous, after i well prepared i had great confidence to teach them. from this small experience, i got to know nothing is impossible as long as you work hard for it.
