Unit8Conflicts in the WorldPassage AReturn from the CageIt was the open space in Austin that initially overwhelmed me. I couldn't adjust to it. The ease with which I could get in a car and drive to any place left me bewildered and confused. Where were the military checkpoints? Where were the armed soldiers asking for my identification papers? Where were the barricades that would force me to turn back?I had just returned to the United States after an absence of 11 years, during which I lived in a refugee camp in Bethlehem, the town where Christ was born. I was not used to freedom of movement, nor to going more than a few miles without encountering military checkpoints.Getting comfortable with my sudden freedom in Austin was going to take time. I had to adjust to no longer feeling like an animal inside a cage. Most days, I felt utterly dazed. I would spend hours sitting on a stone bench at the University of Texas, staring at the squirrels and the birds. The green lawns brought tears to my eyes.My mind would drift to the refugee camp in Bethlehem, and to 3-year-old Marianna, my delightful ex-neighbor. Marianna has never seen a green lawn in her life and has never seen a squirrel. She lives confined to Bethlehem, forced to remain a prisoner behind the checkpoints and the military barricades. The distance between Marianna's house and Jerusalem is no further than the distance from my South Austin home to downtown. Yet Marianna has never been to Jerusalem and is unlikely to go there anytime in the near future, because no Palestinian can venture into the Holy City without a special Israeli-issued permit, and those permits are almost impossible to come by.But adjusting to my sudden freedom paled in comparison to overcoming my fears and my nightmares. When I left Bethlehem, the second Palestinian uprising against Israel's military occupation was already two months under way. The sound of bomb explosions, gunfire and Apache helicopters overhead lingered in my mind. Hard as I tried, I couldn't shake the sounds away. They were always there, ringing inside my head.Now, in Austin, there were nightmares. I would dream either of friends being shot dead, or see pools of blood spilling from human bodies, or that I myself was the target of gunfire. I would wake up in a sweat, terrified of going back to sleep. During the day, the sound of police or ambulance sirens made me jumpy. Helicoptersflying overhead made me uneasy. I had to constantly remind myself that these were most often civilian and not military helicopters. I had to remind myself that the ambulances were not rushing to the wounded demonstrators.I looked around me, and I wondered if anyone realized, or even knew, that the Apache helicopters being used by the Israeli military to shell innocent Palestinian civilians are actually made in this country! As a writer in Palestine, I had regularly visited bombed-out houses in search of stories. The home of a young nurse sticks out in my mind. A few miles away from the stable in Bethlehem where Christ is said to have been born, her house came under attack by Israeli tanks and was completely burned. I held the remains of some of the tank shells in my two bare hands and read the inscription: "Made in Mesa, Arizona."I wanted to stand on a chair and scream this information to everyone walking through the mall. The tear gas civilians inhale in the Palestinian Territories is made in Pennsylvania, and the helicopters and the F-16 fighter planes are also made in the USA. Yet here in this society, no one appears to care that their tax money funds armies that bring death and destruction to civilians, civilians who are no different from civilians in this country.And I worry about the indifference in this country. I worry because someday, young American men will find themselves fighting another Vietnam War - this time possibly in the Middle East - without a notion of what it is they are doing there. And we will have a repetition of history: Mothers will lose sons and wives will lose husbands in an unnecessary war. I have been repeating this warning in all the talks I have been giving in the past nine months. No one took me seriously. I couldn't understand why young Americans, with their whole futures ahead of them, should go to die in a war they will not understand.逃出牢笼刚回到奥斯丁的时候，使我感到无所适从的是这里的广阔自由天地。

Unit1 College LifePassage A学无止境终考的最后一天，东部一所的大学里，一群大四的工科生聚集在一幢教学楼的台阶上，谈论着即刻就要开始的考试。

他们脸上都充满自信。

在参加即将到来的毕业典礼和从事未来的工作前，这是他们最后一门考试。

他们有的谈起了已经找到的工作，有的则谈论着要找的工作。

4年的大学学习给了他们全部的自信，使他们觉得自己足以征服世界。

眼前这场考试，不过是小事一桩。

这门课的教授已经说过，除考场上不能交头接耳外，允许他们带任何书或笔记到考场。

考生们依次进入考场，心情轻松而愉快。

当教授把考卷发给在座的考生后，学生们脸上的笑容更加灿烂，因为考卷上只有五道论述题。

3个小时过去了，教授开始收回考卷。

考生们的脸上充满惊慌的表情，自信已经荡然无存。

当教授收完考卷，看着全班学生时，所有的人都沉默不语。

她扫视着一张张焦虑的脸问道：“5道题答完的有多少？”没人举手。

“答完4道的有多少？”还是没有人举手。

“完成3道题的？2道题的？”考生们有些坐不住了，不安地动了动。

“那么，有没有写完一道题的？我想总有人做完一道题吧！”考场里还是一片寂静。

教授放下手中的考卷，说：“果真不出我所料。

”“我只是想让你们牢牢记住，即使你们已经学完了4年工科课程，在这个领域里，你们还有很多东西不懂。

在你们今后的日常工作中，类似于今天考卷上你们无法回答的问题很常见。

”接着，她微笑着补充说：“你们都会通过考试，但是请记住，即使你们现在已经毕业了，你们的学习才刚刚开始。

”多年后，这位老师的姓名已经被淡忘，但她的教诲却深深地刻在记忆中。

Passage B时光如能倒流四年的学习生涯结束，毕业的那一刻终于到来。

不到两个星期我就要毕业了。

回首往昔，竟不敢相信时间就这样匆匆逝去。

我依然记得第一天去上课时的情景，我一边望着课表背面的地图，一边询问教学楼在哪儿。

现在我已是即将毕业的老生，用羡慕的眼光看待大一新生。

我每天都祈愿时间会凝滞，让接下来的两周过得更慢一些。

剑桥雅思8-第三套试题-阅读部分-PASSAGE 1-阅读真题原文部分:READING PASSAGE 1You should spend about 20 minutes on Questions 1-13 which are based on Reading Passage 1 below.Striking Back at Lightning With LasersSeldom is the weather more dramatic than when thunderstorms strike. Their electrical fury inflicts death or serious injury on around 500 people each year in the United States alone. As the clouds roll in, a leisurely round of golf can become a terrifying dice with death - out in the open, a lone golfer may be a lightning bolt's most inviting target. And there is damage to property too. Lightning damage costs American power companies more than $100 million a year.But researchers in the United States and Japan are planning to hit back. Already in laboratory trials they have tested strategies for neutralising the power of thunderstorms, and this winter they will brave real storms, equipped with an armoury of lasers that they will be pointing towards the heavens to discharge thunderclouds before lightning can strike.The idea of forcing storm clouds to discharge their lightning on command is not new. In the early 1960s, researchers tried firing rockets trailing wires into thunderclouds to set up an easy discharge path for the huge electric charges that these clouds generate. The technique survives to this day at a test site in Florida run by the University of Florida, with support from the Electrical Power Research Institute (EPRI), based in California. EPRI, which is funded by power companies, is looking at ways to protect the United States' power grid from lightning strikes. 'We can cause the lightning to strike where we want it to using rockets, ' says Ralph Bernstein, manager of lightning projects at EPRI. The rocket site is providing precise measurements of lightning voltages and allowing engineers to check how electrical equipment bears up.Bad behaviourBut while rockets are fine for research, they cannot provide the protection from lightning strikes that everyone is looking for. The rockets cost around $1, 200 each, can only be fired at a limited frequency and their failure rate is about 40 per cent. And even when they do trigger lightning, things still do not always go according to plan. 'Lightning is not perfectly well behaved, 'says Bernstein. 'Occasionally, it will take a branch and go someplace it wasn't supposed to go. ' And anyway, who would want to fire streams of rockets in a populated area? 'What goes up must come down, ' points out Jean-Claude Diels of the University of New Mexico. Diels is leading a project, which is backed by EPRI, to try to use lasers to discharge lightning safely - and safety is a basic requirement since no one wants to put themselves or their expensive equipment at risk. With around $500, 000 invested so far, a promising system is just emerging from the laboratory.The idea began some 20 years ago, when high-powered lasers were revealing their ability to extract electrons out of atoms and create ions. If a laser could generate a line of ionisation in the air all the way up to a storm cloud, this conducting path could be used to guide lightning to Earth, before the electric field becomes strong enough to break down the air in an uncontrollable surge. To stop the laser itself being struck, it would not be pointed straight at the clouds. Instead it would be directed at a mirror, and from there into the sky. The mirror would be protected by placing lightning conductors close by. Ideally, the cloud-zapper (gun)would be cheap enough to be installed around all key power installations, and portable enough to be taken to international sporting events to beam up at brewing storm clouds.A stumbling blockHowever, there is still a big stumbling block. The laser is no nifty portable: it's a monster that takes up a whole room. Diels is trying to cut down the size and says that a laser around the size of a small table is in the offing. He plans to test this more manageable system on live thunderclouds next summer.Bernstein says that Diels's system is attracting lots of interest from the power companies. But they have not yet come up with the $5 million that EPRI says will be needed to develop a commercial system, by making the lasers yet smaller and cheaper. 'I cannot say I have money yet, but I'm working on it, ' says Bernstein. He reckons that the forthcoming field tests will be the turning point - and he's hoping for good news. Bernstein predicts 'an avalanche of interest and support' if all goes well. He expects to see cloud-zappers eventually costing 100, 000 each.Other scientists could also benefit. With a lightning 'switch' at their fingertips, materials scientists could find out what happens when mighty currents meet matter. Diels also hopes to see the birth of 'interactive meteorology' - not just forecasting the weather but controlling it. 'If we could discharge clouds, we might affect the weather, ' he says.And perhaps, says Diels, we'll be able to confront some other meteorological menaces. 'We think we could prevent hail by inducing lightning, ' he says. Thunder, the shock wave that comes from a lightning flash, is thought to be the trigger for the torrential rain that is typical of storms. A laser thunder factory could shake the moisture out of clouds, perhaps preventing the formation of the giant hailstones that threaten crops. With luck, as the storm clouds gather this winter, laser-toting researchers could, for the first time, strike back.Questions 1-3Choose the correct letter, A, B, C or D.Write the correct letter in boxes 1-3 on your answer sheet.1 The main topic discussed in the text isA the damage caused to US golf courses and golf players by lightning strikes.B the effect of lightning on power supplies in the US and in Japan.C a variety of methods used in trying to control lightning strikes.D a laser technique used in trying to control lightning strikes.2 According to the text, every year lightningA does considerable damage to buildings during thunderstorms.B kills or injures mainly golfers in the United States.C kills or injures around 500 people throughout the world.D damages more than 100 American power companies.3 Researchers at the University of Florida and at the University of New MexicoA receive funds from the same source.B are using the same techniques.C are employed by commercial companies.D are in opposition to each other.Questions 4-6Complete the sentences below.Choose NO MORE THAN TWO WORDS from the passage for each answer.Write your answers in boxes 4-6 on your answer sheet.4 EPRI receives financial support from………………………….5 The advantage of the technique being developed by Diels is that it can be used……………….6 The main difficulty associated with using the laser equipment is related to its……………….Questions 7-10Complete the summary using the list of words, A-I, below.Write the correct letter, A-I, in boxes 7-10 on your answer sheet.In this method, a laser is used to create a line of ionisation by removing electrons from 7 ………………………….

大学创新英语综合教程 1 Unit 3课文翻译及翻译练习答案Passage 1阅读的乐趣我们会从图书世界里收获什么成果？书籍对于全人类，犹如记忆对于每个人。

书籍涵盖了我们人类的历史，记录了我们的发现，也积累了我们世世代代的知识和经验。

书籍为我们描绘了自然界的奇观和美景,书籍帮助我们摆脱了困境，在悲哀和困苦中给我们以安慰，在我们烦闷的时刻带来欢乐，给我们的脑海装进各种观念，使我们的脑海充满了美妙欢乐的思想，从而使我们能提升自我，超越自我。

东方有个这样的故事：从前有两个人，一个国王和一个乞丐。

国王每天夜里都会梦到自己成了一个乞丐；而乞丐每天夜里都会梦到自己成了一个王子，住进了王宫。

我不知道国王是否如愿以偿真正成了乞丐。

想象有时比现实更加生动逼真。

然而，不管怎么样，我们读书时，不仅可以成为国王（如果我们真这样想），住进王宫里。

而且更为奇妙的是，我们可以神驰群山，或畅游海滨。

我们也可遍访世上最美丽的地方，而无须经受任何劳顿，也没有什么不方便，更无须花费分文。

著名演员麦考利·卡尔金集财富、名望、地位和权势于一身，然而他在自传中告诉我们,他生活中最幸福的时刻还是在读书时。

在给一个小女孩的回信中，他写道，“感谢你那封有趣的来信，我很乐意让我的小女孩高兴快乐，而让我最开心的事莫过于看到她喜欢读书，因为当她到了我现在这个年纪，她会发现书籍比任何蛋糕、玩具、戏剧和风景都要好。

真要是有人拥戴我成为世上最显赫的国王，拥有宫殿花园、珍肴美餐、佳酿华辇、龙袍华衮，以及奴仆成群，但其拥立条件却是不让我读书，我则决不愿去做国王。

我宁愿做一个穷人，蜗居阁楼斗室，与众多书籍为伴，也不愿成为一个不爱读书的国王。

”事实上，书籍为我们构建了一个像是施了魔法的完整的思想宫殿。

简·保罗·理查曾说,从诗人的角度看景色，比坐在宝座上看视野更开阔。

从某种意义上说，书籍给我们的形象比真的现实的东西更生动，正如影像往往比真实的风景更美丽。

Unit 8 Computers and SecurityPassage A You Are the Weakest Link, Goodbye.Do you remember the good old days? Innocent times spent sharing documents and executable files without a care in the world. Okay, every month or so you might encounter a boot sector virus - but they were easy to deal with even if the anti-virus software didn't pick them up.But those long lazy summers disappeared too fast. Macro viruses made Information Technology (IT) administrators grow up fast as they realized there was a type of virus which could spread very quickly throughout an organization. It wasn't unusual to find hundreds of computers within personal company infected by viruses transmitted via email attachments. The IT staff were amongst the fittest departments in your company, running from Personal Computer (PC) to the next cleaning them up.There had to be a better way. Companies now realize that viruses aren't "urban myths", and can have a serious impact on their operations. They invest in anti-virus software on the desktops, servers and email gateways and even put in place procedures to ensure their anti-virus is up-to-date with the very latest detection routines.It sounds like companies have put in place adequate defenses to protect against viruses. But have they?Anti-virus software detects most of the viruses your users are likely to encounter - often without the user even knowing. However, the software must be updated regularly, preferably daily in any large company. Even then, a very new virus can infect your users. With the rapid transmission of files through networks and the Internet, a virus can spread a considerable distance before it can be identified and protected against. Fortunately, only a few viruses ever do this but the likes of Melissa and the Love Bug can inflict serious damage before their progress is stopped. Whilst employees become suddenly aware during the ensuing media excitement, they soon forget about the virus threat as the stories disappear from the news headlines.This is the danger. Complacency can set in when there is no perceived "action" on the virus front with no global crisis, and the importance of being vigilant about viruses recedes in your users' minds. They forget what the big deal was in the first place - after all, the anti-virus software deals with the viruses, doesn't it? And isn't it the IT department's job to look after this sort of thing?Before you know it your users are opening unsolicited attachments once more, downloading unauthorized software, and putting your company's data and credibility at risk. All because the users think that they are working in a safe environment. Employeessee anti-virus software, firewalls and IT departments as guarantees that their computers will work and will be safe. Of course, there aren't any guarantees. Anti-virus software plays one, albeit important, part in the defense of your company from malicious attack but the security of your computer system is only as strong as the weakest link. And that, more often than not, is the human factor.No employer wants to come across as a killjoy or an ogre. Most will willingly accept that the happiest employees are those who feel that they are respected and trusted by their employer. Many companies accept that employees will send and receive a certain amount of personal email and make the odd personal telephone call.However, the worry comes when employees start risking company security in pursuit of personal amusement. Funny screensavers and games downloaded from the Internet can seem harmless enough but they could easily be harboring a dangerous virus.Software downloaded from the net is often unlicensed and unsupported, and may cause conflicts with existing software in use at your company. Unlicensed, pirated software is an ideal vector for a computer virus. Virus writers and hackers often use such software as the ideal "kick-start" for their virus distribution.It is vitally important that employees be educated about the virus threat but this cannot be a one-off event. The potential threat should always be in the back of an employee's mind and precautionary measures should be taken as a matter of course. There is no harm in reminding people about what could happen if they let their guard down. In the end, education is the key to a virus-free environment and this is a continual process. It may not be the most exciting thing on the agenda but it works.The lesson is simple. You can have the best software in the world protecting your company's defenses; you can even be the biggest IT company in the world; but without your users practicing safe computing they will always be the weakest link.PA 你是最薄弱的环节，再见还记得美好的往日时光吗？在那样的纯真年代，我们共享文档和可执行文件，根本没有半点顾虑。
