(10·浙江C篇)

The term “multitasking” originally referred to a computer’s ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大脑训练) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.

   In order to multitask, the brain uses an area known as the prefrontal cortex (前额叶脑皮层). Brian scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you’ve ever dialed (拨电话) a phone number and suddenly forgotten who you dialed when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to anther thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.

   Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don’t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.

   We often don’t remember things as well when we’re trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people’s names---even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.

Over the past 10 years, technologies that have combined computers with telephones have developed. Technologies such as PC fax programs and LAN fax servers(局域网传真服务器) have been used to improve fax communications. The latest computer-based technologies are new mechanisms(机制) which use IP(Internet Protocol, 因特网协议) to send faxes, that is, IP fax.

Traditional fax has a fairly simple usage model. First, the user inserts a document into the fax machine, enters the destination fax number and presses the start button on the machine. The sending machine dials the receiving fax machine. If it connects, the sending machine scans the documents and sends it over the public switched telephone network(PSTN, 公共电话交换网) to the receiving machine. At the same time, the receiving machine receives the document and then prints it.

In IP fax system there are two basic transmission modes: store-and-forward mode and real-time mode. Store-and-forward mode has been widely used. In this mode, the entire document is sent to a network-based server that stores it and then sends it to the destination. Real-time IP faxing is similar to traditional fax. Real-time mode allows two fax machines to directly communicate through a proper standard.

IP fax enables a fax document to be sent 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 would enable users to receive faxes anywhere, anytime with an internet fax address.

　　At the beginning of the century there was a big farm near Los Angeles in California called the Hollywood Ranch (好莱坞牧场). 1 later Hollywood was one of the most 2 places in the world. From the 1910s to the 1950s Hollywood was the film 3 of the world. Every family knew the names of its film 4 , like Charlie Chaplin, Greta Gar bo, Ingrid Bergman and hundreds 5 .

　　People went to Hollywood to make films for the sun. 6 they made films in New York 7 the east coast of America. But then they 8 Los Angeles where there were a great 9 of days of sun every year. 10 they made most films by sunlight, the west coast was a much better place. 11 near Hollywood you can find desert (沙漠) and mountains 12 sea. They did not 13 to travel far to make any films.

　　The first films were 14 . In the late 1920s 15 the “talkies” (有声电影):you can hear people talking and listen to the 16 .

　　After the war Hollywood was successful, but then 17 became popular. People went to the cinema 18 often. So Hollywood began making films 19 it. In the 1970s they found people 20 going to see big and expensive films. Since then films made in Hollywood have been watched all over the world.
