E-mail systems at thousands of companies and government offices around the world were attacked by a virus(病毒)called “Melissa” that disguises(伪装)itself as an “important message”from a friend. In spite of a weekend of warnings，more than 50 000 computers at about 100 places around the world have been attacked by the virus，computer security experts said on Monday.
The virus began to show up last Friday and spread rapidly on Monday by making computers fire off dozens of infected(被传染的)e-mails. Although the virus causes no serious damage to a computer，its effect was far reaching.
To make matters worse，a similar virus called “Papa” was discovered on Monday. Papa is programmed to send out even more infected e-mails than Melissa.
The Melissa virus comes in the form of an e-mail，usually containing the subject line“Important Message”. It appears to be from a friend. The body of the e-mail message says，“Here is that document you asked for...,don’t show it to anyone else.” Attached(附)to the message is a document file.
Once the user opens that file，the virus digs into the user’s address book and sends infected documents to the first 50 addresses. E-mails from the Papa virus include an attached spreadsheet(电子数据文件)file. When the user opens that file，the virus sends 60 infected e-mails.
The reason why this is spreading so fast is that you are getting it from people you know. You should never open documents or attachments from people you don’t know. People who get an unexpected e-mail with the “important message” subject line should delete it immediately and not open the message.

【推荐3】Leading experts on the Internet, technology and policy have shared the same opinion on what we can expect in the next decade when it comes to connectivity and its effects on society.
The Pew Research Center report asked thousands of experts and members of the public for opinions on “the most significant overall influences of our uses of the Internet on humanity” — and some had a rosier outlook than others.
“The smartest person in the world nowadays could well be stuck behind a plough in India or China，” said Hal, Google's chief economist.“Enabling that person — and the millions like him or her — will have a strong effect on the development of the human race.”
Early Internet pioneer David Hughes agreed: “When every person on this planet can communicate twoway with every other person on this planet, the power of nation states to control every human inside its geographic boundaries may start to disappear.”
Wearables (electronic equipment that people can wear) could monitor more than just steps, predicted UC Berkeley's Aron Roberts — or do more than just monitor: “We may literally be able to adjust both medications and lifestyle changes on a daybyday basis or even an hourbyhour basis.”
Microsoft Research's Jonathan Grudin is more pessimistic (悲观的): “By making so much activity visible, it exposes the gap between the way people behave and the way we think they ought to behave.Adjusting to this will be an unending, difficult task.”
And the difference between the rich and the poor will have a new aspect: “Only the welloff (and welleducated) will know how to preserve their privacy，” warned one expert.“Will the Internet make it possible for our entire civilization to fall down together, in one big awful step? Possibly，” admitted Harvard's Doctor Searles.“But the Internet has already made it possible for us to use one of our unique advantages — the ability to share knowledge — to a degree higher than ever before.”
1. According to Hal, in the future, those who will influence the development of human race are________．| A．Google's economists | B．Chinese and Indians |
| C．the educated persons | D．world leading experts |
| A．the development of communication skills |
| B．the suggestions made by computer experts |
| C．the prediction made by the home computers |
| D．the data recorded by the computers worn on body |
| A．the visible activities mentioned above |
| B．the way we thought they ought to behave |
| C．the way people really behave in life |
| D．the rule people ought to obey in life |
| A．Advantages and disadvantages of the Internet. |
| B．Development of the Internet and human beings. |
| C．Knowledge and civilization of human beings. |
| D．Possibilities of the Internet for the future users. |
