Dear__editor，

I__want__to__tell__you__a__strange__thing.It was cloudy that evening.I was riding through a small dark alley after evening class when a strong light shone me.I tried to see it clearly.Then I found out that it was a triangle flying machine which I was sure I had never seen before.Not until a small yellow creature with three eyes came out did I realize what had happened.The creature looked like the alien in the famous movie ET.I was not able to say a word."Is it an alien？" I asked myself.Then the creature asked me how to get to the biology museum.I can't remember what I said to him，but I remember that he smiled at me，saying goodbye politely.

Do you believe me？I can't believe my eyes and ears，either.It may sound amazing，but it did happen that evening.Perhaps，with the development of science it will become obvious whether aliens exist in the world.

Yours__sincerely，

Li__Hua
