难句突破 　　In 1998 the FBI arrested six gangsters who were scouring Las Vegas to recruit a telephone hacker they believed was working for a successful call-girl service (although nobody found him). 　　主体句式：The FBI arrested six gangsters 　　句子译文：本句是一个复杂句，宾语gangsters带有一个who引导的定语从句，在这个定语从句里又含有一个省略了whom的定语从句，该从句修饰hacker。　　句子译文：1998年，联邦调查局逮捕了6个黑帮成员，当时这些黑帮成员正在拉斯维加斯四处招募一名电话黑客，他们相信这个电话黑客是为一个生意兴隆的应召女郎业务工作的（虽然谁也没有找到他）。　　题目分析 　　1. 答案为B，属事实细节题。作者在第一段中提到，虽然法律上禁止卖淫，但并不禁止宾馆房间的私人“舞蹈”和以“热辣裸体女郎”娱乐会议代表的活动。隐含的意思是卖淫活动只是换了个旗号而已。　　2. 答案为A，属事实细节题。根据文章第二段，这起投诉是针对电话公司的，原因是电话公司没有阻止Mr. Munoz的对手利用技术手段将原本打给他手下舞女的电话转接到自己人那里。作为投诉诉由，自然是电话公司服务有问题。　　3. 答案为D，属猜词题。根据文章第二段，Mr. Munoz的对手利用黑客截获他手下的电话，而称这些人为call-poacher的Hilda Brauer也有类似经历，并且因此被挤出市场。可见call-poacher就是转接他人电话的人。　　4. 答案为A，属推理判断题。根据上文，Mr. Munoz和Hilda都遭受了来自竞争对手的不正当竞争，而Mr. Munoz为了对付对手，也聘请了电脑黑客来帮他争夺顾客，可见“应召女郎”服务的竞争相当激烈。　　5. 答案为A，属推理判断题。作者在介绍事情的来龙去脉时是以一种客观的口吻。但从文章开篇和结尾的词汇选择情况来说（Las Vegas has a way with words；fuss, etc），作者对整件事情持一种批判态度。　　参考译文 　　拉斯维加斯是一个擅于词令的地方，在那里，每一个天生的输家都被说成是潜在的赢家。虽然按照该市的法律卖淫为非法行为，但在自己酒店房间里的不公开的“舞蹈”却不算违法---哪怕那只是“热辣金发裸女”用以娱乐来访的会议代表而使用的委婉说法。　　可是，这些私人舞女究竟是怎样知道该去哪个旅馆房间的现在却成了一个棘手的问题。据《经济学人》报道，3月14日，内华达公用事业委员会举行听证会，调查艾迪·穆尼奥兹投诉中央电话公司一事。这家电话公司是斯普林特（Sprint）公司在当地的一个子公司。穆尼奥兹经营着一个室内“成人娱乐”业务。他还出版登有其舞蹈团电话号码的免费报纸《拉斯维加斯快报》。　　他指控其竞争对手闯入拉斯维加斯电话网并且有系统地将旅馆打给《快报》所列号码的电话转接到他们自己的服务人员那里。然后这些竞争对手就派出自己的舞女去跳舞---并且收取本应该属于他的那份钱。穆尼奥兹说在1990年初生意红火的时候他每个月可以从手下的舞女们那里收20000美元的份钱。　　电话公司按照一贯的做法否认有黑客闯入其网络。斯普林特公司声称其“既没有发现也没有人提交任何有明确日期的证据说明电话呼叫被转接了”。但这种说法令人难以信服。希尔达·布劳尔在1998年曾经起诉斯普林特公司和她的竞争对手，但最后由于钱用光了而撤诉。她断言是那些电话猎手把她的“性感女郎”服务挤出了市场。1998年，联邦调查局逮捕了6个黑帮成员，当时这些黑帮成员正在拉斯维加斯四处招募一名电话黑客，他们相信这个电话黑客是为一个生意兴隆的应召女郎业务工作的（虽然谁也没有找到他）。　　穆尼奥兹现在已经雇用了凯文·米特尼克。这位电脑黑客去年曾向一份网络技术刊物《安全聚焦》夸耀自己闯入拉斯维加斯的交换系统之事。米特尼克已经将穆尼奥兹的电话线转接到了洛杉矶的一个办公室；那里的一个临时雇员再把召舞女的电话转接回拉斯维加斯穆尼奥兹那里。这么做的目的就是要绕过斯普林特公司。　　这次听证会也许会让世人更清楚地了解这个世界上最古老的职业是如何将电话黑客纳入其熟悉的领域的。无疑，接下来当这些喧闹平息下来时，这一行当会小心翼翼地避开公众的注意，然后照常经营下去。

Bragging about your fancy new cell phone is a fleeting pleasure; after all, today's coolest models tend to be next month's paperweights. By contrast, the half-life of a cordless phone for the home is measured in years. So if you really want to be ahead of the tech curve, forget the cell-phone wars and check out the new 5.8-GHz cordless phones.

　　Named after the frequency of the radio wave (measured in billions of cycles per second) that carries the signal between the handset and the base station, 5.8-GHz phones promise more clarity because there are fewer devices that operate on the same frequency and thus fewer to cause interference. If you have a cordless phone that is a couple of years old or even a new one that costs less than $50, chances are it is a 900-MHz model that is highly susceptible to static or buzzing from baby monitors, wireless speaker systems and your neighbors' 900-MHz phones. The newer 2.4-GHz units, introduced as an improvement over the 900-MHz models, do get less static, but wireless home networks and microwave ovens can still trigger a snap-crackle-pop effect. Not so the 5.8 GHz. So far, only a few companies sell the new models, and they don't come cheap. Uniden's TRU5865 costs $149, while the Vtech 5831 is $179. I preferred the Uniden because it was static free both inside my apartment and up to a block away. Its compact design hides the antenna inside the handset, and the glowing orange keys and display look sharp. The VTech got equally clear reception indoors, but I could stray only a few buildings down the block before buzzing set in.

　　But is it really worth an extra $100 (or more) to step up to 5.8 GHz? Maybe. When I tried out the Panasonic KX-TC1481B, a $39 900-MHz model, I could hear other conversations and even music coming through the phone. I got much clearer reception with the Motorola MA351, a $60 2.4-GHz model--except when I turned on my microwave oven and was assaulted by weird vibrating noises coming through the handset. Still, the Motorola is a decent option at a fair price.

　　No matter which kind of phone you're considering, a few other factors are worth keeping in mind. First, ask about battery life. While I liked the reception best on the Uniden, for example, it can go only four hours between charges vs. eight on the Vtech.

　　Next, find out if the phone is analog or digital. Both 5.8-MHz phones are digital, but that's not always the case with the models that use other frequencies, and this makes them an easier target for eavesdroppers. The best digitals use digital spread-spectrum (DDS) technology, which sends the signal down a broad range of frequencies to ensure that it gets through.

　　Finally, shop at a store that offers a money-back guarantee. That way you can torture test the phone for a few days. Then, once you're certain everything's O.K., go ahead and start bragging about it to all your friends.

1. How does the author introduce the topic?
　　[A]Explaining a phenomenon.

　　4. 答案为B，属事实细节题。原文对应信息是第二段“5.8-GHz phones promise more clarity”。

　　5. 答案为C，属事实细节题。本题的关键是对句子“If you have a cordless phone that is a couple of years old or even a new one that costs less than $50, chances are it is a 900-MHz model that is highly susceptible to static or buzzing from baby monitors, wireless speaker systems and your neighbors' 900-MHz phones.”的理解。详细解释参见难句突破部分。

　　参考译文

　　炫耀你的新款手机如何的神奇只是瞬间的快乐，因为今天最酷的机型到下个月就只能拿它当镇纸用了。相反，家用无绳电话的使用期却是有些年头的。所以如果你真想走在科技发展的前沿，那么就请你忘掉手机大战，去试试新款5,800兆赫无绳电话吧。

　　这款5,800兆赫电话是以在电话听筒和基地台之间传递着信号的无线电波（每秒几十亿赫）频率来命名的。这款电话之所以能保证其音质更为清晰，原因在于几乎不存在其它同频率运转的设备，因此造成的干扰也就几乎不存在。如果你家的无绳电话是你两、三年前购买的，或者是你花了不超过50美元的价格新买的，那么你这部电话很可能是900兆赫的。这款电话极易受静电的干扰，婴儿监控器、无线扬声器系统以及邻居家的900兆赫款电话都能使它发出嗡嗡声。2，400兆赫机型被推荐为900兆赫机型的改良款，它的确能减少静电干扰，但是家庭无线网络和微波炉还是无法避免对其产生噼里啪啦的干扰作用。但是这款5,800兆赫电话不会出现这种情况。迄今为止，仅有几家公司销售新机型，而且售价不菲。友利电TRU5865型售价149美元，伟易达5831款是179美元。我偏爱友利电电话是因为无论在室内还是在一个街区之外，它都不受静电的干扰。小巧的外形设计把天线置于听筒内，色彩鲜明的橙色按键和显示器看起来非常时髦。伟易达电话的室内接收效果也同样清楚，但是我沿街区刚走了几幢楼它就开始有嗡嗡声了。

　　真的很值得你多花100美元（或更多）去购买5,800兆赫电话吗？或许还真值。当我试用松下售价39美元的900兆赫KX-TC1481B款无绳电话时，我能听到别人的对话，甚至还有音乐通过听筒传过来。摩托罗拉售价60美元的2,400兆赫MA351款无绳电话接听效果还要更清楚一些——当然除了我打开微波炉受到从听筒里传来的奇怪的震动噪音冲击的时候。尽管如此，摩托罗拉价格公道，算是个不错的选择。

　　不管你在考虑购买哪一款电话，你都应该谨记其它几个方面的因素。首先，询问电池的寿命。比如说，虽然我喜欢友利电的接听效果，但相对于伟易达8小时的电池使用时间，它的使用时间仅为4小时。

　　其次，看是模拟机还是数字机。两个品牌的5，800兆赫电话都是数字的。但是使用其它频率的话机通常不是这样的，这就使这些话机更容易成为偷听者的目标。最好的数字话机使用的是扩展频谱（DDS）技术，这种技术能够使信号在更广的频率范围内发送，这样能保证信号成功发送。

　　最后，要在提供有退款保证的商店购买。这样你就能做几天的破坏性试验。一旦你能确定这部电话各方面性能都不错，那么你就去跟所有的朋友炫耀去吧。

Many people think that information technology and biotechnology will rule the 21st century. Robert Birge, a chemist at the University of Connecticut, is trying to combine them, by making computer memories out of protein.

　　The protein in question is bacteriorhodopsin (bR), a molecule that undergoes a structural change when it absorbs light. By using genetic engineering to tweak wild bR from a bacterium called Halobacterium salinarum, Dr Birge and his colleagues have made a variety of the molecule that they claim is well-suited to act as an element of a computer's memory. Hit with a green light, it adopts one shape. Hit subsequently with a red light, it twists itself into another. Then, if hit with blue light, it resets itself into its original state.

　　To make a memory from the protein, Dr Birge suspends elements made from it in a transparent plastic cube known as a cuvette. A pair of lasers arranged at right angles to one another write data into the cuvette by shining in turn on "slices" through the plastic matrix. The first laser, which produces green light, sweeps the whole cuvette, causing its protein contents to take on a shape that (in binary code) is designated as "zero". The second laser, which produces red light, then stimulates particular sites to take the second shape. This corresponds to "one" in binary code. Once the lasers are switched off, data recorded this way will, according to Dr Birge, remain stable for more than 12 years.

　　To read the stored data, a low-powered red laser is shone slice by slice through the cuvette. This does not disturb the conformation of the protein molecules; but those in state "zero" absorb light at this wavelength. A machine placed behind the cuvette detects this absorption pattern and translates it into the appropriate string of ones and zeroes. Once the contents have been read into a more conventional storage device, the cuvette can be wiped clean and reset by illuminating it with a blue laser.

　　Dr Birge says that each cuvette can now hold about seven gigabytes of data (a small laptop computer might have about this much space on its hard drive). He hopes to boost that figure to ten gigabytes by finding a better-performing variety of the protein. Only those with deep pockets, however, could afford the $25,000 cost of each device.

　　Luckily for Dr Birge, the deep-pocketed American air force thinks that bR cuvettes could be a good way to equip its aircraft and satellites with light, high-density devices to store the mountains of images collected during reconnaissance missions. A protein-based memory is particularly suitable for this, because the bR molecule is robust enough to withstand the barrage of radiation from space that wreaks havoc on conventional magnetic-memory devices operating at high altitude.

1. What is the passage mainly about?
　　[A]What will rule the 21st century.
　　How bacterial protein can be used in computers.
　　[C]What we can get from bacterial protein.
　　[D]How to make bacterial protein.

2. The application of bR turns out to be___________.
　　[A]very trustworthy
　　rather superficial
　　[C]somewhat contradictory
　　[D]quite encouraging

3. The basic problem of applying bR to computer lies in ____________.
　　[A]limited space on hard drive
　　its complexity
　　[C]its high price
　　[D]its limited users

4. Which of the following is not the advantage of bR?
　　[A]Working at higher altitude.
　　Light weight.
　　[C]High density.
　　[D]Safe from strong radiation.

5. Which of the following is true according to the text?
　　[A]bR has a wide variety of application in life.
　　The protein molecules have stable characteristics.
　　[C]The data recorded with bR can be kept for a long time.
　　[D]The new device will replace conventional storage device.

　　难句突破

　　A pair of lasers arranged at right angles to one another write data into the cuvette by shining in turn on "slices" through the plastic matrix.

　　主体句式：A pair of lasers …write data …

　　结构分析：本句是一个简单句。句子的主语是“a pair of lasers”，“arranged at right angles to one another”是后置定语，用来修饰主语；谓语是“write”；“by”做伴随状语，短语“in turn”意思是“轮流”。

　　句子译文：一对事先调整到一个合适角度的激光器通过塑料矩阵轮流在“切片”上闪烁，这样就把数据写入试管。

　　题目分析

　　1．答案为B，属主旨大意题。文章第一段点出了本文的论题。

　　2. 答案为D，属推理判断题。综观全文，虽然bR用在电脑中，其售价不菲，但是其使用效果，以及在军事领域中的运用都说明这一应用是非常鼓舞人心、令人看好的。

　　3. 答案为C，属事实细节。原文对应信息是“Only those with deep pockets, however, could afford the $25,000 cost of each device.”这一句话中，关键是要理解“deep pockets”的含义。它的意思是“财富，资产”，暗示了这一产品售价高昂。

　　4. 答案为A，属事实细节题。原文对应信息是“…because the bR molecule is robust enough to withstand the barrage of radiation from space that wreaks havoc on conventional magnetic-memory devices operating at high altitude.”，我们无从判断bR是否能在更高的高度上正常运转。

　　5. 答案为C，属事实细节题。原文对应信息是“This corresponds to "one" in binary code. Once the lasers are switched off, data recorded this way will, according to Dr Birge, remain stable for more than 12 years.”。

　　参考译文

　　许多人认为，信息技术和生物工程学将主宰21世纪。康涅狄格大学的化学家罗伯特•伯奇正在设法通过用蛋白质做电脑存储器的方法把它们结合在一起。

　　所说的蛋白质就是细菌视紫红质(bR)，即一种分子，当它吸收了光线以后，就会发生结构变化。伯奇博士和他的同事应用遗传工程从一种叫做嗜盐菌的细菌中提取混乱无序的细菌视紫红质，培养出各种各样的分子。他们声称这些分子非常适合做计算机的存储元件。若用绿光对它进行瞬(时干)扰，它呈现一种形状；若再用红光瞬扰, 它便变成另一种形状；然后再用蓝光瞬扰，它便恢复到其原始状态。

　　为了用蛋白质做存储器，伯奇博士把用蛋白质研制成的元素悬浮在一个透明塑料试管中。此时，一对事先调整到一个合适角度的激光器通过塑料矩阵轮流在“切片”上闪烁，这样就把数据写入试管。产生绿光的第一个激光器扫描整体试管，导致其中的蛋白质成分呈现一种在二进制编码中被定为“0’的形状。产生红光的第二个激光器刺激某些地方，使其呈现第二种形状，此形状对应于二进制编码中的“1”。据伯奇博士说，一旦这些激光器被断开后，用这种方式记录下来的数据能稳定地保留12 年以上。

　　读取存储的数据时，就让一个低能红色激光器通过试管一片一片地发光。这不会干扰蛋白质分子的构造，但那些“0”状态的蛋白质分子将吸收这个波长的光。放置在试管后面的机器可检测吸收图形，并把它转换成适当的一列含有“1”和“0”的数字。当其中的内容读入一个更常规的存贮设备后，通过蓝色激光器的闪烁就可使试管清零复位。

　　伯奇博士说，每支这样的试管现在可保存约七十亿字节的数据(一台小型手提电脑的硬盘也就这么大的空间)。他希望通过找到一种性能更好的蛋白质把这个数字提高到100亿字节。不过，只有那些家财万贯的人才能买得起每台价值25,000美元的计算机。

　　伯奇博士感到幸运的，财力雄厚的美国空军认为bR试管可能是一种用重量轻、密度高的存储设备装备其飞机和卫星的好方法。这种设备可以用来储存储存侦察飞行中收集到的大量图像。蛋白质存储器特别适合这种用途，因为bR分子十分强壮，足以承受来自太空的大量辐射。这种辐射会对在高空运行的常规磁芯式存储器造成严重破坏。
