I am sorry I have to ask half a day off.I received a telephone call from my wife just now,My son got a clod and my wife is not in this city.I must go back to my home and take my son to see a doctor.And I will get touch in our boss in the evening.I still have some work which haven't been finished.I'm sure I will try my best to make you satisfied. Internet has been more and more important in mordern life.We work with it,study on it ,search information on it and paly computer games on it.It is possible for us to stay at home and shopping on it.It's a miracle!Some people said that people can't live without Internet nowadays.Maybe that's really true.But ,beside the advantages,it still have a lot of disadvantages.For example.many students give up their study to play on the Internet.It's very serious.
