E-mail is a new way of communication in every area all over the world. It is a means of ’meeting’ people with similar interests or problems. E-mailers ’write’ letters at leisure on their computers, then send them through their telephone line to an on-line computer (联机上网的电脑) far away. E-mail addresses — either names or numbers — automatically send mails to the right locations (站点). E-mailing is not a live conversation, but reply can be back at once or within hours, depending on how often the receiver checks in his computer.
E-mail can also create friendship and draw families closer. E-mailers sit in comfortable chairs and ’chat’ with the friends or relatives in other parts of the country or of the world in front of the screen. Linda, a first-year student at Oxford University in Britain, drops a few lines to her mother in New York whenever she is near a computer. ’It’s funny, ’says her mother. ’We talk more

[单项选择]The UK government has some way to go in building trust in its handling of genetic modification in agriculture.
Lessons learnt in Britain ( and no doubt elsewhere ) from the BSE (疯牛病) crisis were evident in the UK government’s announcements last week of plans to change the way it regulates genetically modified crops. Out goes any lingering assumption that the technology is inherently safe, and in comes a new requirement for industry to demonstrate practically that its products will not have adverse ecological effects.
In a welcome move, a new steering group of scientists will be able to commission research it considers necessary on the ecological impacts of genetically modified crops. The government, in turn, promises not to allow the commercialization of any crop until the scientists are reasonably satisfied that it is safe to proceed.
The government’s attempts to build public trust in its scientific advice, and to include public views in its policy decisions, however, l

C. With its handling of genetic modification in agriculture, the practical technology is booming.
D. A strict assumption and a new requirement may have more probably helped.

Scientists in the United States have developed a method that may help to predict earthquakes earlier. They say it could give people who live in deadly earthquake areas enough warning to leave before an earthquake hits.
Currently, the most modem systems for predicting earthquakes find them only a short time before the event. Like most strong earthquakes, the one that hit southwestern China in May wasnot identified early enough for people to flee the area. That earthquake killed sixty-nine thousand people.
But scientists who study earthquakes are reporting that new technology could measure very small changes in the Earth’s surface. Their report was published this month in Nature magazine.
