[简答题] Internet Users Turn Addicts
If you’’re an Internet user, you know who you are. They are among all of us in society, although many may choose not to acknowledge that they too, frequently use the Internet. As I sit here and look across the street, I see a man in front of his own computer; the screen glowing against the window behind him. He does not use his personal computer for work, he is a farmer. He has become what is known as an "Internet Junky".
The addiction begins innocently. At the start, you are not even aware of the possibilities that may form from your excessive computer use. You begin to take an avid interest in e-mailing with your friends and family. Once the novelty of keeping in touch with your colleagues wears off, and researching starts to bore you, you may possibly expand your computer usage to chatting. Yes, chatting. It is something that is becoming more acceptable in our lives, but it is still looked down upon by many skeptics.
[填空题]Dear Sir/Madam,
You recently advertised for a job from which it seems you are looking for a native English speaker to teach English on a part-time basis.

Nowadays I am working (part-time) at Shanghai Sunrise International School, at Angels Kindergarten and tutoring a Japanese kid and a Shanghainese businessman on weekends. I have also been at Shanghai American School for a month during my last summer vacation. This summer I will be available on a full time basis.
