【美文诵读】
Dear Mike，
I'm very sorry to hear that you are in hospital with_eyesight_decreasing① and obesity and some other diseases.I hope that you will recover soon.
You said that your illness was caused by surfing the Internet too much.That's true.Some of my friends，who often do such things，are beginning to feel bad too.They say that they can't see now as clearly as before.And my teachers often tell us that it's_bad_for_us_to_stay_late
_surfing_the_Internet_every_day②.
