[16] "I learned from my experience with romance on the Net that people aren't always what they seem. The guy I met, for example, was very nice but also quite mixed up. The trouble is you get lonely housewives talking to someone and they think, 'This guy sounds nice compared to what I've got.'"

[17] But I don't think anyone who is married or in a sound relationship should really be spending hours talking to someone else and ignoring their nearest and dearest. While Parker provided her own therapy by putting her experiences down on paper, she recommends others take up the online counselling offer, or log off from the Worldwide Web gradually.

[18] "It's like smoking. It's not a good idea to suddenly go cold turkey. People often e-mail me about the problem and I tell them to gradually wean themselves off and not to switch to a scheme where you pay per hour for online time. If they break their resolution, all they end up with then is the same old problem plus money difficulties for the long hours they have spent logged in to the Internet."

[19] Computer whizz Steve Phillips grins at the mention of Internet Addiction Disorder (IAD)--he's been there, done that. Now 28, and a seven-year veteran on the Internet, he spends a mere 10 to 15 hours ' for entertainment" on the Web each week, A few years ago, when he was in the grip of his addiction, that was the amount of time--10 to 15 hours--he spent online each day.

[20] "I'd go to polytechnic and log on at 9 a.m. and sometimes I'd stay online until 9 at night. Then I'd go home and plug in the laptop and stay online until 4 or 5 a.m.," says the Internet systems maintenance ex-pert.

[16]“我的网上罗曼史让我明白了，人们并不总像他们表现出来的那样。例如，我曾认识一个网友，他很不错，但也很迷糊。让人伤脑筋的是，当你介绍那些寂寞的家庭主妇与某人聊天时，她们会想：‘与我的那位比起来，这家伙听起来不错。’”

[17]可我认为，对于已婚的人或者拥有一份良好关系的人来说，实在不应该把大量的时间耗在与别人聊天上，而把自己至爱至亲的人冷落在一旁。帕克通过把自己的经历写成文章提供了她自己的治疗方法，她劝告别人要接受网上咨询服务，或者逐渐地远离万维网。

[18]“就像抽烟上瘾一样，一下子戒掉烟瘾是难以让人接受的。人们常常给我发电子邮件谈及此事，我就告诉他们要慢慢地戒掉网瘾，不要进入付费网站。如果他们不听告诫，到头来不但旧病难除，而且还要面临长时间上网带来的经济困难。”

[19]计算机能手史迪夫·菲利普笑着提及沉迷网络症（IAD）——他一直在网上呆着，干的就是那个。他今年28岁，是一个有7年网龄的老手，现在他每周只上网“玩”10-15小时。几年前，他上网成瘾，难以自拔，每天在网上耗费的时间就达10－－15小时。

[20]“我上午9点去理工专科学校上网，有时在网上呆到晚上9点。回家以后又在便携式电脑上继续玩，直到凌晨四五点钟。”这位因特网系统维护专家说。来源:考试大-经典译文考试

Discovery of Penicillin

On Alexander Fleming's desk were some small plates with germs (细菌). One evening, he forgot to cover one of the plates.

　　When he arrived the next morning, he found a spot of green mold (霉菌) in one plate. This is not strange because the room was very damp(潮湿). But　Fleming　didn't　throw　out　the　spoiled,because　something　unusual caught his attention. On the uncovered plate, near the green　mold, he found no germs. That meant the mold had killed the germs　there.Fleming began to study the mold. It grew and grew. Then he noticedvery small drops of liquid on the surface of the mold. Maybe this was　the chemical that was killing the germs.

Fleming drew off the liquid with a absorbent tube (吸管), drop by drop.He put this liquid in a clean test tube (试管). When he put the liquid in　another test tube with germs, it killed the germs in that tube. He called　the liquid penicillin (青霉素).

Arctic Melt

Earth's North and South Poles are famous for being cold and icy. Last year, however, the amount of ice in the Arctic Ocean fell to a record low1.

Normally, ice builds in Arctic waters around the North Pole each winter and shrinks during the summer. But for many years, the amount of ice left by the end of summer has been declining.

Since 1979, each decade has seen an 11.4 percent drop in end-of-summer ice cover2. Between 1981 and 2000, ice in the Arctic lost 22 percent of its thickness -- becoming 1.13 meters thinner.

Last summer, Arctic sea ice reached its skimpiest levels yet. By the end of summer 2007, the ice had shrunk to cover just 4.2 million square kilometers. That's 38 percent less area than the average cover at that time of year. Andit's a very large 23 percent below the previous record low, which was set just 2 years ago. This continuing trend has scientists concerned There may be several reasons for the ice melt, says Jinlun Zhang, an oceanographer at the University of Washington3 in Seattle. Unusually strong winds blew through the Arctic last summer. The winds pushed much of the ice out of the central Arctic, leaving a large area of thin ice and open water4.

Scientists also suspect that fewer clouds cover the Arctic now than in the past. Clearer skies allow more sunlight to reach the ocean. The extra heat warms both the water and the atmosphere. In parts of the Arctic Ocean last year, surface temperatures were 3.5℃Celsius warmer than average and 1.5℃ warmer than the previous record high5.

With both air and water getting warmer, the ice is melting from both above and below. In some parts of the Beaufort Sea6, north of Alaska and western Canada, ice that measured

3.3m thick at the beginning of the summer measured just 50 centimeters by season's end. The new measurements suggest that melting is far more severe than scientists have seen by just looking at ice cover from above, says Donald K. Perovich, a geophysicist at the U. S. Army Cold Regions Research and Engineering Laboratory in Hanover, N.H.7

Some scientists fear that the Arctic is stuck in a warming trend from which it may never recover.

Caught in the Web of the Internet

沉湎因特网

IN THIS ARTICLE: Getting hooked on the Internet isn't confined to a few computer nerds. It's on the rise everywhere--and women are the most likely addicts. Ingrid Parker, once a slave to Internet chatrooms, found her experiences so devastating that she wrote a book to help other addicts break the habit. --Editor

本文简介：沉醉于因特网而难以自拔的人已不再局限于少数计算机迷了。对因特网痴迷的人越来越多，到处都是--妇女最可能成为对因特网着迷的人。英格丽德·帕克一度沉溺于网上聊天，后来发现那段经历使她损失不小，因而写了一本书以帮助其他网上君子们改掉上网成瘾的毛病现那段经历使她损失不小，因而写了一本书以帮助其他网上君子们改掉上网成瘾的毛病。

[1]It's the equivalent of inviting sex addicts to a brothel or holding an Alcoholics Anonymous (AA) meeting at the pub. Internet addicts tired of their square-eyed, keyboard tapping ways need look no further than the Web for counselling. There is now an online counselling service at www.relate.org.nz for Internet obsessives. Just e-mail the details of your Internet-induced crisis and help comes direct to your inbox. The new breed of cybertherapists see nothing strange about offering help through the very medium that is swallowing their clients' free time and splitting their marriages.

[2] Sue Hine, of Relationship Services, says: "Internet obsession has become a more noticeable problem over the last 18 months. At least this is an area addicts are familiar with and they'll be able to use it as a tool to overcome their obsession." Nor do experts worry that the Relate Website might become a favourite--a place to spend hours online in the name of Internet therapy. Dependency is always a risk with any form of counselling. There are various strategies we can adopt to keep that in perspective, says Hine.

[3] Though some may regard Internet addiction as another dubious ailment dreamed up to keep therapists in work, Relationship Services says the problem is real.

[4] Internet usage is up to four-and-a-half hours on the Web each week, compared to three-and-a-half hours a year ago. Therapist Robin Paul says there tend to be two scenarios. Some people meet through chatrooms and fall in love. It's like having an affair, then they meet and it's like a whirlwind honeymoon. It's devastating for the person left behind and quite often it has no real foundation.

[5] I saw one couple who were still together but it was very rocky. He met someone on the Net and went overseas to meet the woman. Then he left his wife and children to be with her. In another case I saw recently, a man left his three children to be with a woman (who was) leaving her four children. It's terribly hard on the kids when this happens.

[1]上网成瘾如同邀约好色的人逛妓院，或者在小酒馆里举行"嗜酒者互诫协会"(AA)会员集会。网迷们疲劳地盯着显示屏，敲击着键盘，只想通过万维网寻求咨询。现在有一种为网迷开设的网上咨询服务，你只需把上网引发的“危机”详情用电子邮件发出去，就会从你的邮箱中直接收到帮助信息。新式的计算机治疗专家认为，通过网络寻求帮助并不奇怪，正是它吞噬着网迷们的自由时间，而且危及到他们的婚姻。

[2]“关系服务网站”的苏·海英说：“在最近的18个月中，上网成瘾已经成为一个非常突出的问题。服务网站至少是网迷熟悉的地方，他们将能够把它作为戒掉网瘾的工具来使用。”专家们也并不担心服务网站会成为上网者最爱光顾的地方--一个网迷们花费在线时间进行网上诊疗的地方。依赖于任何形式的咨询服务总是靠不住的。海英说，我们可以采取各种措施使服务网站发挥有效作用。

[3]有些人认为，沉醉于因特网的人是患有某种假想的精神失调症，这只是使得精神治疗专家Computers Computers are changing our life. We can do a lot of things with a computer. Such as, to write articles, watch video CDs, play games and do office work. But the most important use of a computer is to join the Internet.We don’t need to leave home to borrow books from a library or to do shopping in a supermarket on line. Computers help us live a more convenient life. 计算机计算机正改变着我们的生活。我们能用计算机做很多事。例如写文章，看视频CD，玩游戏，办公等等。但计算机的最重要的用途是访问互联网(Internet)。(通过网络)我们不用离开家就能去图书馆借书或到超级市场购物。计算机为我们的生活提供了极大的便利。 For the disadvantages, we spend too more time on computers, children trapped in the Internet games. more serious, scientists have found that computers are somewhat harmful to our health. Generally speaking, computer is very important to our modern life. 在缺点方面，我们在计算机上花费了大量的时间，孩子们沉湎于网络游戏(而荒废了学业)，更严重的，科学家已经发现计算机(幅射)在一定程度上是有害于我们的健康的。总之，计算机对于我们现代生活非常重要。
