用英语向全班报告同学们近视的主要原因.

Answer 1

hello everybody,
today i'd like to say something about shortsightedness.
before i start my topic,here's a question for you——what's the primary cause do you think that lead to your shortsightedness.(then listen to their question.)
OK,as we all know,the fist one to blame is TV.we sart to whatch tv when we were still a child,we do it everyday but ignore the problem that it hurts our eyes terribly,or we clearly know the harm but just leave it all behind,so,the TV hurts us everyday,everyyear .
another sinner is book.we start to read from the primary school to now,sitting with the wrong posture,too close to the book and reading with light that too dim or too stong is all the reason for shortsightedness.
the last but not the least,the use of computer increased the chance to become myopia.teenagers now use computer several hours a day and somes just more than 10 hours,it's a big harm.
