Do you want to watch a hot movie while chatting with your friend on the phone, or shop with your mobile while on a train? The ongoing construction of a new telecommunication service will make these things reality, very soon.

It is reported that China is to issue its first license for the commercial use of third generation telecommunication technology(3G) early next year.

The so-called 3G technology will enable mobile phone users to enjoy high speed Internet based services. It will help increase mobility in many areas of our lives.

Nowadays, many mobile phones also allows you to send e-mails or read the latest stories on the Internet, but their services are limited by their transporting speed, which is only 10 kilobytes(KB) per second. But 3G will enable you to connect to the Internet with a speed of up to 2 megabytes(M) per second.

If recent mobile technology is like riding bike on a country road, then 3G will make you fly on the information highway. For example, a mobile phone with 3G technology will enable you to download a three minutes MP3 song within two minutes. But at the moment, it will take you up to an hour to do this with your mobile phone.

In the near future, we’ll expect high-speed access to the Internet, entertainment, information and electronic commerce services wherever we are not just at our computers or television sets.

In the UK and many other European countries where 3G services have around since 2003, 3G has already become a part of modern business life: Nowadays, employees are able to spend some of their working hours at home: The new technology allows the emergency services to provide a video link with a hospital or doctor for patients who need special care.

       A．Download a three minute MP3 song with two minutes.

       B．Call our friends through video phones:

       C．Surfing the Internet.

       D．Do online shopping.

       A．10 times              B．20 times              C．100 times            D．200 times

Is there a magic cutoff period when offspring become accountable for their own actions? Is there a wonderful moment when parents can become spectators (旁觀者) in the lives of their children and shrug, "It' s their life," and feel nothing?

When I was in my twenties, I stood in a hospital corridor waiting for doctors to put a few stitches in my son' s head. I was asked, "When do you stop worrying?" A nurse said, "When they get out of the accident stage." My mother just smiled faintly and said nothing.

When I was in my thirties, I sat on a little chair in a classroom and heard how one of my children talked incessantly, disrupted (打斷) the class, and was headed for a career making license plates. As if to read my mind, a teacher said, "Don't worry. They all go through this stage, and then you can sit back, relax, and enjoy them." My mother listened and said nothing.

When I was in my forties, I spent a lifetime waiting for the phone to ring and the cars to come home, the front door to open.

My friends said that when my kids got married I could stop worrying and lead my own life. I wanted to believe that, but I was haunted by my mother' s wan ( 淡淡的 ) smile and her occasional words, "You look pale. Are you all right? Call me the minute you get home."

Can it be that parents are sentenced to a lifetime of worry? Is concern for one another handed down like a torch to blaze the trail of human frailties and the fears of the unknown? Is concern a curse? Or is it a virtue that elevates us to the highest form of life?

One of my children became quite irritable recently, saying to me, "Where were you? I' ve been calling for three days, and no one answered. I was worried! ! !"

I smiled a wan smile.
