It's March, 2050.

Frank and Mary Smith wake up in their comfortable house in the morning and switch on the bedroom computer to get the latest news. They used to read the Times，but changed to electronic newspapers many years ago.

There is the usual news about space： another space flight has returned from Mars and scientists have discovered a new planet. Then they turn to business news：the US dollar has risen greatly in Shanghai, one of the world's leading business centers. Mary tells the computer to buy 5,000 dollars，and there is a quick answer that it has been done.

As they watch the screen, Mary orders one of the household robots to make coffee for them. Frank disappears into the study to join in a video conference with his partners around the world. He is a computer engineer, working for several companies. This is his third job;he used to be in marfceting and then television.

Mary has a quick look at the shopping channels ― the usual selection of electric cars， household robots and cheap travel offers ― before picking up the video phone to talk to her assistant. She also has a job and she is doing medical research. Both she and Frank used to have an office desk in London, but in 2014 they decided to move to the seaside and work from home.

Frank and Mary have one daughter, Louise, who also has her own workstation at home. She goes to school only one day a week, mainly to play with other students. Classrooms disappeared in 2030 because there was no longer any need for them;communication systems have made it much easier to learn at home.

Louise，now thirteen，is studying Chinese at present, which has become a world language as important as English. Louise has many Chinese friends. They communicate by computer.

According to the family doctor, Louise will live to at least 130. Her wish is to work for a few decades(十年)and then spend her time on music and painting.

根据短文内容，回答下列问题。

1. Why do Frank and Mary switch on the bedroom computer in the morning?

2. Does Mary read business news?

3. Who makes coffee for Mary and Frank?

4. How does Frank work from home?
