【题目】Technology that connects computers to telephones has developed very fast in the last ten years. This is clear in the development of the fax. A traditional fax can include many documents and is simple to send. It is rather like a copier combined with a telephone. First, you insert a document into the fax machine, enter the fax number and then turn on the machine. If it connects, the sending fax machine reads the document and sends it to the receiving fax machine. At the same time, the receiving machine receives the document and then prints it.

But technology never stays still. New technology like PC fax programs and LAN fax servers (局域网传真服务器)have recently been introduced to improve fax communications. The latest improvement is the IP fax which uses Internet Protocol(因特网协议)to send faxes.

  There are two basic ways of sending information using the IP fax system: store-and-forward or real-time. Store-and-forward ways of sending messages are widely used. In this mode, the entire document is sent to a network-based server that stores it and then sends it on to the receiving fax. Real-time IP faxing is closer to sending a fax in the traditional way. Real-time mode allows two fax machines to directly communicate and send the material more efficiently.

IP fax can send a fax document from one person to another. A fax machine or a computer can be used to send or receive the fax. IP fax also allows e-mail to be used to receive faxes. This enables users to receive faxes anywhere at anytime as long as they have an Internet fax address.

How northern Europeans beat the winter blues

Ask a child from northern Europe to draw two pictures one on a rainy day and a second in the sunshine and this is what you will get: in the first, as raindrops fall from the top of the page, the man behind the window has an unhappy expression. When a yellow sun sends out some light from the corner, the man is smiling.

Northern Europeans associate rain with sadness and sunshine with happiness. They think this is true because they are so aware of how their environment affects them. 【1】 In October 2008, a group of researchers examined the influence of different daily weather factors, including temperature, wind and sunlight, on 1,200 participants. The conclusion was that good or bad weather had little effect on people’s feelings. 2 A person who is upset on dark or cold days suffers from a negative mood, and he will be likely to experience a sad winter. This is the basis of an illness called Seasonal Affective Disorder (SAD). 3

Kalayjian, professor of psychology at Fordham University, advises that we should take steps to strengthen the brain’s system against weather-driven mood changes. Research on SAD has been focused on the brain’s response to darkness and light. When our eyes detect darkness, the brain gives off melatonin, which starts sleep cycles. 4 It takes over to help us wake up and feel better when we detect light. “We can encourage people to take charge of their feelings,” says Kalayjian. “We tell them to leave the computers and the indoor games and get out there in the sun. 5

A day of rain can potentially destroy your plan and affect your mood. But as the Scottish comedian Billy Connolly once said: “There is no such thing as bad weather, only the wrong clothing.”

A. Another chemical called serotonin, however, can make people happy.

B. That’s when people can recharge their serotonin and get a better mood.

C. Most studies prove that a negative feeling is associated with bad weather.

D. They determined that people actually differ in their sensitivity to weather changes.

E. Yet that link has no scientific basis.

F. It is seriously doubted among the people who suffer from SAD.

G. It affects about 10% of the population of northern Europe each year.
