Atomic Cars

原子汽车

Every motorist dreams of a car of the future that does not have to be refuelled every few 每个司机的梦想未来的汽车,它不必被refuelled每隔几

hundred miles, a car that will cost little to run because there is no outlay on petrol.

100英里,一辆汽车那将花费小跑,因为没有经费油。

"Of course", you hear it said by an optimistic motorist, "the answer is the atom. Harness “当然”,你听到持乐观的司机,“回答是原子。治理

atomic power in a car, and you'll have no more worries about petrol. The thing will run for 原子能在一辆车里,你就不再担心汽油。将竞选的东西

years without a refill."

年却抓点药。”

And, theoretically, he is right. The answer is the atom. If atomic power could be used in a 而且,从理论上来讲,他是对的。答案是原子。如果原子力量能被用于

car, one small piece of uranium would keep the engine running for twenty or more years. Of 车,一件小的铀要保持发动机正在运转了20年或以上。的

course, this would cut the cost of running a car by quite a few hundred pounds, depending 历程,这将把运行成本相当一辆按不同,几百英镑

upon how much you spend on petrol.

But is this science-fiction-like picture of the atom exploding peacefully beneath the bonnet 但这是原子爆炸的照片science-fiction-like和平在阀盖

of a car possible? In theory it is, since already the atom has been harnessed to drive

一辆汽车可能吗?理论上说,既然已是推广香港的原子开车

submarines, and an atomic engine is already in existence. But, say the experts, there are

潜水艇和原子引擎已经存在。但是,专家们说,那儿有

many problems still to be conquered before such an engine can in fact be fixed into a car.

许多问题仍然是征服主动力前确实可以被固定到一辆汽车上。

Now what exactly are these problems that stand between you and a car that you will never 现在那是什么问题,站之间你和一辆车,你永远不会

have to refuel? Frankly, most of them can be summed up in one word—radiation. An atomic 需要加油吗?坦白地说,他们中的大多数可以归结为一个word-radiation。原子

reactor, the kind of engine that would produce energy by atom-splitting, throws off

反应堆,这种引擎,会产生能源atom-splitting、摔投了

radiation, extremely dangerous radiation. These rays are just as dangerous as when they are 辐射,非常危险的辐射。这些射线一样是危险的,因为当他们

carrying an atomic engine would also have to carry many tons of lead in order to prevent the 带着原子引擎也必须携带大量吨的铅以防止

radiation from escaping.

辐射逃跑。

Since a car made up of tons of lead is rather impracticable, the only answer at the moment 既然一辆车由吨的铅是相当做不到的,唯一的答案的时候。

seems to be the discovery or invention of a metal that will be strong enough to hold in the

似乎是发现和发明出一种金属,这将成为一个坚强的人,能够保持

on the way to an atomic car. However, even after the invention of a protective but light

在原子的车。然而,即使是在保护的发明,但重量轻

metal, two other problems still remain, those of economics and safety.

金属,另外两位问题仍然存在,经济和安全。

It is extremely doubtful whether at the beginning a really economic engine could be made, 这是极为怀疑开始一个真正经济引擎可以被做,

that is, one cheap enough to make it worth putting in a car. But it seems safe to say that

那是一条便宜,让它值得投入一辆车。但似乎有把握说

eventually, as technology and mass production come in atomic engines, the price will go 最终,在技术和大规模生产进来原子引擎的话,我们的价格将会去

大学英语快速阅读课文Wildlife Conservation带翻译 课后习题答案

Wildlife Conservation In my children's lifetimes, I believe gorillas, chimpanzees and orangutans ( 猩猩) will all become extinct in the wild. So the question we have to ask ourselves is this: do we

want our children to see only in zoos what used to exist in the real world? It is the great apes that will disappear first, because there are so few of them left, and because they're so vulnerable to changes in their habitats.

Many of the threats to these animals result from a global economy and not local pressures. The threat to the orangutans in Indonesia, for example, is largely a result of deforestation and the risks to apes and chimpanzees in Africa result from the timber

trade and the demand for bush-meat. The two work together: logging opens up the forest, which means that the bush-meat can be got out fast, to Kinshasa or to London. If we want to avoid the disaster, people in developed

Sometimes he covered quite long distances on foot. On other occasions he got on a bus or even a train, and simply sat there until someone asked for his ticket. Generally the police brought him home. "Why do you do it?" they used to ask. "You aren't unhappy at home, are you? .... " "Of course not," Johnny replied. "Then why?" "I just like seeing places," Johnny told them. 等到他 7岁的以后,约翰尼经常离家出走,一年内有两到三次。有时他步行到很远的地方。其他时候,他通常坐公共汽车或甚至坐火车外出,并朴素地坐在里面直到有人来买票。通常警察来带他回家。“为什么你要离家出走?” 警察们问他,“你在家里是幸福的,不是吗? .... ”“当然不是不幸福,”约翰尼回答道。“那是为什么呢?”“我只是喜欢外出探险, ”约翰尼告诉他们。 Johnny continued to "see places" although everyone tried to stop him. His parents used to watch him closely, and so did his teachers; but sooner or later Johnny managed to slip away. As he grew older, his favorite trick was to hide on a long distance truck. Sometimes he used to travel hundreds of miles before anyone discovered him.

Book One Unit Four Passage One Directions: You will have 10 minutes to read this passage quickly and answer the following questions from A, B, C and D. You should decide on the best choice. Youth Speak If you think the English language is getting shorter, you may be right. From news bytes to text-messaging to famously shorter attention spans, we're saying less—and relying on slang more. Why? With so much of our daily communications taking place online these days—and that doesn’t include just e-mail, but text-messaging on increasingly teenier devices—it seems everyday English has been reduced to a code of accepted abbreviations, mysterious combinations of numbers and letters, and even symbols masquerading as facial expressions. :) Often in all lowercase(小写字母) letters. Certain numbers, “2” and “4” in particular, play starring roles—replacing, respectively, “to” and “for”—but the far more interesting development is the embrace of the number “3” for the letter “e” (“b3” and “th3”), and the number “8” for the sound it makes (“gr8” and “l8r” for “great” and “later”). While some of these brave new acronyms(首字母缩拼词) can actually be self-explanatory (“u” for “you” and “ur” for “your”) or fairly logical (“b4” for “before”), or can highlight the sounds the letters ma ke (“qt” for “cutie” and “cu” for “see you”) or act as abbreviations (“cuz” for “because”), or can be just straightforward acronyms (“bff” for “best friends forever”), some do border on strange (“peeps” for “people”). Some terms that have been in circulati on for quite a while are pretty recognizable: “lol” (“laughing out loud”), “btw” (“by the way”), and “imho” (“in my humble opinion”). Some, meanwhile, are puzzling: “iykwim” (“if you know what I mean”), “mtfbwy” (“may the force be with you”), and “wysiwyg”(“what you see is what you get”). At times, this alphabet-soup vernacular (本国语,俗语) feels absolutely confusing to everyone but linguists and computer geeks. But it’s difficult to argue with it s speed—or even its necessity—when forced to use a toothpick-sized device to reply to an office memorandum (备忘录) while driving a car (not recommended or legal but, unfortunately, all too common). With the exception of “peeps,” though, all of the above examples are mostly used in written slang. Spoken slang is a whole o ther story. And it’s here that the younger generation truly has its say (pun intended). Today’s slang changes faster than yesterday’s password. That’s because words that were popular only a couple of years ago have lost favor—among t oday’s teens—for no reason at all. These include: “sweet”, “excellent”, and “awesome” (which all mean “good”). But, then, slang is short-lived by nature. In order for slang to be slangy, it has to have a feeling of perpetual newness. Slang is like fashion: never “in” for long. Americans eventually tire of even the most popular words, and by natural selection, only the strong survive.

Negotiating for mutual satisfaction谈判的双赢 有一个传奇故事,已成为谈判的民间传说的一部分: 一个哥哥和姐姐已在一些吃剩的饼争吵,每个大的一块。每个人都希望得到一个大的一块,但又不想被对方欺骗。当男孩的获得控制刀的权利,并准备为自己切份大的馅饼的时候,他们的父母来到了现场。 在国王Soloment传统,家长说,“等一等吧!我不关心谁是切成两块馅饼,但谁也得给其他有权选择他们想要的一块。”自然,为了保护他自己,男孩切分成两个大小相等的块板。 这则故事可能是杜撰的,但其中蕴含的道德仍然持续至今。很多情况下,事件中的主角们需求没有形成对立。如果焦点转换形式,由为了击败对方而转变成战胜问题,那么大家都能受益。 在合作双赢的谈判中,我们都在尝试制作这种结果,让每一方都获得可以接受的增益。争执被视为人类自然天性中的一部分.,如果争论被认为一个需要被解决的问题,可以发现创造性的解决方案,来加强双方的立场,各方甚至可能会更密切地联系在一起。 这可能是一种巧合,但在劳资双方的集体谈判用馅饼作比喻被习惯性地谈论着。一方通常会说,“我们只是希望我们的馅饼的形状!”但是,如果馅饼是固定金额的钱,一方获得收益,另一方必然会失去,考虑下面的例子: 在谈判陷入僵局后,工会进入罢工。如果工会获胜,在罢工期间损失将超过工资上涨的好处。相反,罢工后,公司管理者们损失会比没有罢工工会所要求的成本更高。因此,双方都有损失。如果没有罢工,在一个相互信任的气氛,他们可以实现和解,使双方得到他们想要的。 尽管在这个逻辑,我们继续看到这里不仅仅是组织罢工的工会和公司管理者们输了,还有公共经济,甚至国家利益受到损失.为什么会这样呢?也许部分问题可以是用蛋糕来打比方.当我们都关注在这个固定的金额上,并开始来回争论、作出要求,反要求,结论和最后通牒,没有创造性的结果.与之相反,我们应该看到我们真正的兴趣是在于我们的互补性和彼此的影响,并询问对方,“怎么能够通过一种方式,一起把这个蛋糕做大,使双方获得更大的发展空间?” 显然,这并不单单指劳动关系,还有每一个持续发展的谈判关系.如果你思考一会儿,你将会看到,几乎涵盖了你所有的谈判的想法。 如同自然不会创造相同的人类一样,您的需求和我的需求通常是不相同的。因此,这有可能使我们双方都取得胜利。 每个人的独特性似乎是一个公认的事实- 至少在一个智力水平,那么为什么我们接手大多数谈判时,好像对方是偶然遭遇到的敌手,必须在对方的花费的情况下才使你满意。原因是在大多数的谈判中,讨论的是“固定金额“,通常的钱。 我们许多人已经习惯于在我们的青年时期接受金钱。被引导相信自己喜欢的颜色应该是绿色的--绿色的美元。听人说话,你有时会认为他们是生活美元的符号中.但如果您认为很多谈判仅仅是以前为中心,那你就错了。人们并不是讲话的方式或看起来所表现的那样。钱当然是需要的,但它只是其中之一。如果你忽视他们的其他需要,满足人们的美元需求,也不能使他们感到高兴。让我通过一个假设的情况证明这一点。 而通过一个晚上都在翻阅一本杂志,两个人一起生活--丈夫和妻子说——发现一个作为广告片的背景使用古董时钟。

第五单元 Text A-1 一个年轻的,盲人电脑专家 有时,有些被认为是消极的东西实际上是工作中的资产。虽然他只有18岁而且是失明的,在InteliData技术公司,一个在美国各地有办公室的大型软件公司。 Suleyman Gokyigit几乎是最好的计算机技术人员和程序员 “在我们公司加上另一个去年10月,两个不同的计算机网络使我们疯狂。”道格拉斯·布劳恩,一个InteliData的副主席。“我们甚至不能互相发送电子邮件。”在三个星期里,Gokyigit 一个托莱多大学二年级学生,在InteliData的办公室做兼职,创建了需要合并两个网络的软件。“没有一个公司的350名其他雇员可以在三个月里做完这个工作。”布劳恩先生说。“苏莱曼的确可以“看”到电脑的核心。” Gokyigit先生的天赋,正如布劳恩先生所说的,是一个不寻常的能力,他可以形成机器内部的想法。“计算机允许我到这个世界,为我做任何我想做的,”Gokyigit先生说,他是一位计算机科学与工程专业成绩最好的学生。 像大多数用计算机工作的盲人一样,Gokyigit先生使用一个语音合成器,这是一种电子装置,它可以用机械的声音大声地朗读出显示在他的机器的文字。他完全依赖于记忆。把合成器调到最高速度,他几乎记得所有他听到,直到至少完成一个项目。当合成器在说时,Gokyigit 的脑海里用坐标“绘制”电脑屏幕(如横三,纵二)和在网格上记下每个图标的位置,这样他可以用他的鼠标调用文件。 这个年轻的程序员也在家里用硬件,有一部分是由于他高度发达的触觉。Mitzi Nowakowski,一名在InteliData的办公室经理,记得他去年在移动中轻松地断开连接和重新连接他们的计算机系统。“通过感觉,苏莱曼能找到连接器的位置,识别和连接速度远远超过其他大多数人通过视觉做到。”她说。 几个月前,在前往旧金山的旅行中,布劳恩先生使用他的笔记本电脑很难连接到公司的主机。他需要特殊的数字来进入4个InteliData文件。没有让某人手动搜索一本厚厚的书来查计算机地址,他让Gokyigit先生,一个已经把地址簿记在脑海里的人“在十秒内”产生适当的数据。布劳恩先生说。 大部分的学生程序员的速度来自于忽略有时计算机的中断的能力。当在输入时,他仔细地听着合成器。他的又长又瘦的手指在键盘上飞舞。“没有什么似乎动摇他的注意力,”Nowakowski太太,他的老板。 Gokyigit先生是唯一的24小时可工作的公司员工。“我们认为他我们问题的首要解决者,”布劳恩先生说。 A-2 梦想成真 我们都有梦想。然而我们中很少有人满足他们。通常,一个梦想的死亡就像它产生一样迅速,因为我们缺乏信心保持它。当我长大到足以理解生活的现实,我意识到社会为年轻美丽和智慧的成就给了很高的价值。这个发现给了我一些发展我的梦想的想法。 我知道美丽是我永远不会有的。所以我没有梦想成为美丽的。但我不认为这是坏事,因为它迫使我集中精力去开发我的其他品质。人们看到的缺陷只是他们外表上的残疾。人们没有注意到在每个有缺陷的人的内心隐藏的能力。 我的梦想是简单的。当我在中学的时候我梦想着成为一名打字员。我总是希望能够掌握打字机。这个神奇的机器将成为我找到工作的护照。我来自一个有着五个孩子贫穷的家庭。我父母能给我们最好的东西是一个良好的学校教育。但是,当然,这一成就被证明是不能保证得

Book One Unit Six Passage One Directions: You will have 10 minutes to read this passage quickly and answer the following questions from A, B, C and D. You should decide on the best choice. Choose the Perfect Christmas Tree How to pick the perfect specimen and care for it over the holidays? Nothing adds to the excitement of the holiday season like a decorated Christmas tree. And, now that natural trees have been declared the winner in the “which-is-greener” debate, you’ll want one that reflects your own style. Enviro-winner Natural Christmas trees are more enviro-friendly for several reasons. According to Ross Gough, executive director of the Christmas Tree Farmers of Ontario, “If composted corr ectly, a natural Christmas tree will break down within two years so there is nothing for the landfill. Buying natural also means you’re supporting a local farmer and reducing your carbon footprint.” Back to the basics Not only will you be doing your bit fo r the environment you’ll also be in vogue. “With the downturn in the economy, people want to keep things simple but beautiful. Nothing looks better or is more authentic than a natural Christmas tree,” says Lena Maher, a Montreal-based eco- decorator and event planner. Choose your type There are four basic types of trees sold at farms and nurseries: Scotch pine: Brought over by European settlers, the Scotch pine has been the perennial favourite throughout North America. Its sturdy branches that curve upwards mean this tree can handle plenty of ornaments. Needles are in sharp clusters of two with colours ranging from blue-green to yellow-green. It has decent needle retention, but it requires plenty of pesticides to get a healthy tree, so it’s falling out of favour. Balsam fir: With its dense, dark-green foliage, the balsam is quickly becoming the new darling of natural trees. It’s tall but narrow pyramid shape is topped off with a spire-like tip—perfect for a star. The flat, rounded needles are softer, making it one of the easiest to decorate so you can get the kids to help. It’s also very aromatic, holding its scent and needles for longer than most other trees. An excellent choice if your tree is going to be up longer than three weeks. White spruce: This tree has strong slender branches with dense green to bluish-green foliage. It has a perfect form with a symmetrical, cone-shaped crown and evenly spreading branches. Needles are short, stiff and blunt at the end, so it can be a bit prickly to decorate. It has excellent needle retention, but its one downside is a rather disagreeable odour when the needles are crushed. Fraser fir: Similar in shape to the balsam, the Fraser fir is quickly becoming the designer natural tree. It has a rich, dark green foliage with soft silver undertones. Its upper branches have a gentle upward curve, giving it a pleasing U-shape. It’s pleasant scent and ultra-soft needles with good retention are also a plus. Due to its longer growing cycle, this will be a much more expensive
