My invention-- Automatic-writing pen

Automatic-writing pen is a pen that can write itself. The other special thing it has is wings. The wings, no matter where you are, can fly back to you. Easy to use and effective, you just have to say the word, and it will write down what you say.

  The pen is very environmental-friendly because it use solar power. All you have to do is put it under the sun for 30 minutes, and you can use it all day long.

  Also, when you listen to the teacher, but have no time to make notes, you can use this pen then, too. You just have to set the program on it, and it will write down everything the thacher says.

  The pen is very cheap. You don’t have to worry about the prise because evertbody can afford, even if you are poor or rich. So, I think, this pen may be popular soon. What do you think?

這是我英文班的短文題目,我有請外籍老師批改過一次,但有些文法和我學的不一樣,所以我又自作主張的改了!若有人發現錯誤,請不吝指教!寫的不好,見諒!
