拓展阅读：2015年职称英语考试词汇选项做题必杀技

职称英语考试的过程中除四川职称英语面试题库模拟了掌握一定的知识积累外，还需要掌握一些必要的做题技巧，这有利于四川职称英语面试题库模拟我们提高做题效率。下面就看看怎么做职称英语词汇选项题吧。

必杀技：

准备一本正式出版的'英语同义词词典，拿到字典后，用标记纸在每个字母首页进行标记，方便在考试时查阅。具体形式请参看群资料。

教材练习不用做，把答案勾画出来，只需记住其中题目划线部分或者答案是词组的，其余不用看。

考试时看到有教材中的词组题则直接答上，其余的查词典。

详解：

职称英语考试允许带一本正式出版的，并非针对职称英语考试而编写的词典。而本题考核内容就是同义词(词组)，显然使用同义词典效率更高。

词组记忆相对容易而查词典找同义词组相对较困难，又因试题来自教材练习4-6题，所以必须记住教材中的词组题。教材词汇练习一共150题，其中有词组的也就20个左右，记住绝对没有困难;

因职称英语词汇数量有限，直接查同义词词典，一般前三个义项就会有答案。

参考答案及解析

11. 【答案】D

【参考译文】她是个直率、讲求实际、工作努力的妇女。

【试题分析】此题既是形近词辨析又是近义词辨析题。

【词义辨析】practical讲求实际的;实践的：practical method讲求实际的 *** 。practical指在日常生活中能运用常识、知识、 *** 等，着重于行动，而非思想或想象。A. practicable可行的、行得通的，不能用来修饰人：a practicable plan可行性方案。B. favorable有利的：This decision is favorable to us. 决议对我们有利。C. feasible可行的，用法同practical : a feasible scheme可行的计划。

12. 【答案】D

【参考译文】当一个人被邀请共进晚餐时，按惯例应给女主人带件礼物。

【试题分析】此题为近义词辨析题。

【词义辨析】common共同的，共有的，强调“大家都这么做”：It’s our common concern. 这是我们共同关心的问题，common practice表示“惯例、常规”。A. general普遍的;大多数人的：This sugar is a general favorite. 这种糖大多数人都很喜欢。B. usual通常的;习惯的：As usual, he gets up at 6:30 a. m. 像往常一样，他六点半起床。C. ordinary平凡的;平常的.：ordinary people普通百姓。此题是说被邀请到别人家吃晚饭应该给女主人带件礼物，这种做法已形成惯例，所有的人都遵守，所以用“common”比“general”更合适。

13. 【答案】A

【参考译文】母亲希望儿子不要轻率行事。

【试题分析】此题为词组辨析题，实质考搭配。

【详细解答】首先可排除B、C两项，因为avoid为及物动词，常用于avoid(doing)sth.

结构中。ask也为及物动词，没有ask from这样的词组。D. protect虽然能与from搭配使用，但一般用于protect…from结构中，表示“保卫……，使不受……伤害”。A. keep from阻止;抑制：keep from talking like that不要那样讲话。

14. 【答案】B

【参考译文】约翰逊夫妇在决定买下之前先查看了那所房子。

【试题分析】本题是词组意义辨析题。

【词义辨析】look out意思是“当心”或“向外看”，通常作不及物动词词组使用;look over是及物动词词组，意为“检查，浏览，查看”;look after照料，照看;look on旁观

【作者建议】此题可用排除法。

15. 【答案】A

【参考译文】过了好长时间我手上的伤口才完全愈合。

【试题分析】此题为近义词辨析题。

【词义辨析】heal跌打、烫伤的治愈;伤口的愈合：The wound has been healed. 创伤已经治好了。B. recover恢复，一般用人做主语。如：He recovered his eyesight after the operation. 手术后他恢复了视力。C. improve改善;提高：improve working conditions改善工作条件。D. cure治愈，主要指内部得病的治愈，不用来指伤口的愈合：cure *** . of his stomachache治愈某人的胃病。

16. 【答案】D

【参考译文】尽管多次失败，但他们仍然充满希望和决心。

【试题分析】此题为词义辨析题。

【词义辨析】instead of表示“代替，充当”，后接名词，代词，动名词;in search of寻找，寻求，后接名词，代词，动名词;in spite of表示“尽管，不顾”，引出让步状语;because of因为，由于，后接名词，代词，动名词。

17. 【答案】A?

【译文】我把你错认作你兄弟了。

【试题分析】词语搭配题。

【详细解答】mistake A for B是一个固定词组，意思是将A错认作B。

18. 【答案】A

【参考译文】除少数人外其他人都无权接触这些保密文件。

【试题分析】此题为近义词辨析题，尤其是A、B两项易混淆。

练习：

1.The country says that the investment of US $14 million is big enough for developing that country’s chip industry.

A　Right B　Wrong C　Not mentioned

2.That country gives top priorities to developing chips for military purposes.

A　Right B　Wrong C　Not mentioned

3.Although the licensing fees are not very high, that Far Eastern country cannot afford to pay.

A　Right B　Wrong C　Not mentioned

4.Many western countries ban the exporting of the most advanced chip-making technologies to that country to prevent them from being used for military purposes.

A　Right B　Wrong C　Not mentioned

5.Currently, almost all the flagship chipmakers in that country are owned by American investors.

A　Right B　Wrong C　Not mentioned

6.Mainstream chip production technology develop rapidly.

A　Right B　Wrong C　Not mentioned

7.More than 10 chip plants being built in that country are an example of self-reliance.

A　Right B　Wrong C　Not mentioned

答案与题解：

1.B　本题给出的信息是错误的。最后一段说到，如果新建的芯片中心能在改善该国在芯片行业的被动形势中起重要作用，该国认为：“... the US $14 million investment is still rather *** all”。

2.C　文章没有提供这方面的信息。

3.B　文章提到专利费较高，此句说较低，与原意不符。

4.A　本题给出的信息是正确的。第二段有这样一句话：Currently, chip plants in this country are in a passive situation because many foreign governments don’t allow them to import the most advanced technologies, fearing they will be used for military purposes.这就是选A的依据。

5.C　文章没有提供这方面的信息。

6.A　选A的依据是第三段之一句：... mainstream chip production technology shifts from one generation to the next every three to five years ...

7.B　本题给出的信息是错误的。第四段第二句说明，这些芯片工厂的技术主要是从日本和新加坡进口的。

译文：微芯片研究中心成立

为了开发先进的微芯片生产技术，这个远东国家建立了一个研究中心，该中心启动资金为一千四百万美元，可以帮助该国开发自己的芯片工业，不必总是依赖于进口技术。

该中心将会应用自己的研究技术和设施，为本国芯片厂家开发新技术。这个国家名列首位的芯片制造公司说，芯片中心的成立可能使这个国家摆脱从他国购买即将淘汰的.技术的困境。由于许多外国 *** 担心先进技术会被用于军事目的，不允许这个国家的芯片生产厂家进口前沿技术，所以这些生产厂家处于一种被动局面。另外，由于这些芯片生产厂家必须向技术提供者支付高额的许可费，这也构成了他们决定要自力更生的一个重要原因。

由于主流芯片生产技术每隔 3～5年就要进行更新换代，所以掌握了新技术的厂家就可以以较低的成本制造出较好的芯片，而那些耗费数十亿美元建立起的厂家，如果设备落后，也将会被生产商所淘汰。

几个芯片厂正在建立之中，每个厂的造价都在几百万美元，其中大部分资金都流向了海外设备商和技术所有者——主要是日本和新加坡。

如果新建的芯片中心能在改变该国芯片行业的被动形势中起到重要作用，该国承认，一千四百万美元的投资仍是微不足道的。该国正在开发综合技术，大部分投资将用于与技术和知识产权所有者建立联盟。

The Biology of Music

Humans use music as a powerful way to communicate. It may also play an important role in love. But what is music, and how does it work its magic? Science does not yet have all the answers.

What are two things that make humans different from animals? One is language, and the other is music. It is true that some animals can sing (and many birds sing better than a lot of people). However, the songs of animals, such as birds and whales, are very limited. It is also true that humans, not animals, have developed musical instruments. 1

Music is strange stuff. It is clearly different from language. However, people can use music to communicate things — especially their emotions. When music is combined with speech in a song, it is a very powerful form of communication. But, biologically speaking, what is music?

If music is truly different from speech, then we should process music and language in different parts of the brain. The scientific evidence suggests that this is true.

Sometimes people who suffer brain damage lose their ability to process language. However, they don’t automatically lose their musical abilities. For example, Vissarion Shebalin, a Russian composer，had a stroke in 1953. It injured the left side of his brain. He could no longer speak or understand speech. He could, however, still compose music until his death ten years later. On the other hand，sometimes strokes cause people to lose their musical ability, but they can still speak and understand speech. This shows that the brain processes music and language separately.

By studying the physical effects of music on the body，scientists have also learned a lot about how music influences the emotions. But why does music have such a strong effect on us? That is a harder question to answer. Geoffrey Miller, a researcher at University College, London, thinks that music and love have a strong connection. Music requires special talent, practice, and physical ability. That’s why it may be a way of showing your fitness to be someone’s mate. For example, singing in tune or playing a musical instrument requires fine muscular control. You also need a good memory to remember the notes. And playing or singing those notes correctly suggests that your hearing is in excellent condition. Finally, when a man sings to the woman he loves (or vice versa)， it may be a way of showing off.

However, Miller’s theory still doesn’t explain why certain combinations of sounds influence our emotions so deeply. For scientists，this is clearly an area that needs further research.

词汇：

automatically .自动地

note 音符

stroke 中风

注释：

1.It is also true that humans, not animals, have developed musical instruments：人研制出了乐器，而动物则不能。Develop：研制，例如：Scientists are developing new drugs to treat cancer.科学家们正在研发新药用以治疗癌症。

练习：

1.Humans, but not animals, can sing.

A　Right B　Wrong C　Not mentioned

2.People can use music to communicate their emotions.

A　Right B　Wrong C　Not mentioned

3.We use the same part of the brain for music and language.

A　Right B　Wrong C　Not mentioned

4.Geoffery Miler has done research on music and emotions.

A　Right B　Wrong C　Not mentioned

5.It’s hard for humans to compose music.

A　Right B　Wrong C　Not mentioned

6.Memory is not an important part in singing in tune.

A　Right B　Wrong C　Not mentioned

7.Scientists does not know all the answers about the effects of music on humans.

A　Right B　Wrong C　Not mentioned

答案与题解：

1.B　第二段的第三句：It is true that some animals can sing (and many birds sing better than a lot of people).可以看出有些动物会唱歌，而不只人类会唱歌。

2.A　第三段的第三句：However, people can use music to communicate things — especially their emotions.这句清楚表明，人们可以用音乐来表达情感。

3.B　第四段说明：科学证明人们用大脑的不同区域处理语言和音乐。在第五段，作者用Vissarion Shebalin的例子进一步说明人脑处理语言和音乐的位置不同，Shebalin中风以后不能讲话也听不懂别人的话，但他却能创作乐曲。

4.A　第六段的第四句：Geoffrey Miller, a researcher at University College，London，thinks that music and love have a strong connection.这句说明Miller对音乐和爱(情感)的关系进行了研究，他得出的结论是：音乐和爱有密切的关联。

5.C　文中没有提及创作乐曲是否困难。

6.B　第六段有一句：You also need a good memory to remember the notes.此句说明必须具备好的记忆力记音符才能唱得符合调子。

7.A　最后一段讲的是：科学家们需要做更多的研究才能解释为什么有些声音影响我们的情感会如此之深。也就是说，科学家不能全部解释音乐对人类的影响。

译文：音乐生物学

人们把音乐作为一种高效的交流方式，在爱情中它也可能会起到重要的作用。但是音乐是什么?它又是如何起到神奇的效果?科学界还没有给出答案。

哪两项事物使得人类不同于动物?一个是语言，另一个是音乐。当然一些动物会唱歌 (并且许多鸟唱得比很多人都好听) ，但是，动物的歌声是有限的，比如鸟类和鲸鱼。同样，是人类而不是动物开发出了乐器。

音乐是个奇怪的东西，它与语言有明显的不同。但是，人们能够用音乐去传达——尤其是情感。当音乐与歌曲中的语言结合在一起的时候，它就是一种强有力的表达方式。但是，从生物学来讲，音乐是什么?

如果音乐与语言真的不同，那么我们应该在大脑的不同区域内对音乐和语言进行加工处理，科学证据也证实了这一点。

有时，受过脑损伤的人会丧失他们处理语言的能力。但是，他们不会自动地丢失音乐才能。比如，维沙翁·舍巴林，一位苏联作曲家，在1953 年得了中风。他的大脑的左半边受到损害，他再也不能说话或是理解别人的话，但是他仍然能够谱曲，直到十年后他离开人世。另一方面，中风有时会使人们丧失音乐能力，但是他们仍然能够说话也能听懂别人的话。这就说明大脑是分别加了处理音乐和语言的。

通过研究音乐在人身体上的物理效应，科学家也了解到许多关于音乐是如何影响情感的。但是，为什么音乐对我们有如此强烈的影响?这是一个更难回答的问题。伦敦大学学院的研究员杰弗里·米勒认为音乐和爱有紧密的关，音乐需要特殊才能、练习和体能。这也许是一种方式让你展示你适合做某人的伴侣。比如，按调唱歌或者弹奏乐器需要有很好的肌肉控制力。你也需要有好的记忆力来记住音符。能正确地演奏或者唱出这些音符也证明你的听力也非常好。所以，当一个男人唱给他心爱的女人时(反之亦然) 音乐就可能成为一种展示的方式。

然而，米勒的理论仍然不能解释为什么声音的特定结合可以深深地影响我们的情感。对于科学家来说，这显然是一个需要深入研究的领域。

The Magic Io Personal Digital Pen

1 Check out the io Personal Digital Pen launched by Logitech：It’s a magic pen that can store everything you write and transfer it to your computer. And you don’t have to lug a hand-held device along with you for it to work.1

2 Logitech’s technology works like this：The pen writes normally, using normal ballpoint pen ink2. But while you are writing, a tiny camera inside the pen is also taking 100 snapshots per second of what you are doing3, mapping your writing via a patchwork of minute dots printed on the paper. All this information—the movement of your pen on the paper, basically — is then stored digitally inside the pen, whether you are writing notes or drawing complex diagrams. You can store up to 40 pages worth of doodles in the pen’s memory. As far as you are concerned4, you are just using a normal pen.

3 It is only when you drop the pen into its PC-connected cradle that the fun begins. Special software on your PC will figure out what you have done, and begin to download any documents you have written since the last time it was there. Depending on whether you have ticked certain boxes on the special notepad, it can also tell whether the document is destined to be an e-mail, a “to do” task, or a diagram to be ed into a word-processing document. Once the documents are downloaded you can view them, print them out or convert them to other formats.

4 The io Personal Digital Pen is a neat and simple solution to the problem of storing, sharing and retrieving handwritten notes, as well as for handling diagrams, pictures and other non-text doodling. You don’t have to carry a laptop along with you. All you have to do is just whip out the pen and the special paper and you are off5.

5 It is a great product because it does not force you to work differently—walking around with a screen strapped to your arm, or carrying with you extra bits and pieces. The pen is light and works like a normal pen if you need it to, while the special notepads look and feel like notepads. The only strange looks will be from people who are curious why you are writing with a cigar.

6 The io Personal Digital Pen also has potential elsewhere. FedEx6, for example, is introducing a version of the pen so that customers can fill out forms by hand — instead of punching letters into cumbersome devices. Once that data is digital more or less anything can be done with it — transferring it wirelessly to a central computer, for example, or via a hand-phone. Doctors could tran *** it their prescriptions direct to pharmacies, reducing fraud; policemen could send their reports back to the station, reducing paperwork.

词汇：

lug 吃力地携带 snapshot快照 patchwork 拼凑的东西，杂絵

注释：

1.And you don’t have to lug a hand-held device along with you for it to work：to work是动词不定式，用作目的状语，修饰lugb for it是work的逻辑主语。it指代io Personal Digital Pen。

2.ballpoint pen ink：圆珠笔墨水

3.a tiny camera inside the pen is also taking 100 snapshots per second of what you are doing：is also taking 100 snapshots和of what you are doing之间插入了per second。

4.As far as you are concerned：就你而言

5.…you are off：……你就能开始工作了

答案与题解：

1.F 第二段介绍神奇笔的工作原理。笔内装有一个摄像头，把写的字或画的图转换为数码，存储在笔内的记忆装置里。

2.B 第三段介绍把神奇笔存储的信息下载到电脑中的过程，其中很重要的一个设备是将笔与电脑相连接的cradle(笔座)。

3.A 第五段介绍神奇笔的优越性，使用的方式和使用普通笔一样，不用携带显示屏，不用带附件。所以，这段的内容可以概括为A friendly and convenient device。

4.C 最后一段列举了有可能使用神奇笔的其他地方。

5.D 文章中多处都提到the io Personal Digital Pen用起来很方便，普通的笔怎么用，the io Personal Digital Pen也怎么用。因此，it works like an ordinary pen是答案。

6.E download和使用cradle的内容可在第三段之一句、第二句中找到。

7.A 题干中的convenient和when you work away from home or office提示我们要选A。第五段之一句说，外出时不用携带显示屏或附件。

8.F 第二段第三句是选F的依据。

译文：神奇的io私人数字笔

仔细看看由Logitech公司发明的io私人数字笔吧。这是一种神奇的笔。可以将你写的所有东西储存下来并转换到计算机上，而你在使用这种数字笔时却不必携带手持设备。

Logitech技术的工作原理如下：这种笔使用一种普通的圆珠笔墨水，和平常一样写字。但是当你写字时，笔内的一个极小的摄像头也在以每秒钟100张的速度对你所写的内容进行快速拍摄，通过印在纸上的'小点块拼出你所写的内容。然后，无论你是记笔记还是画复杂图表，所以的信息——基本上都是笔在纸上的移动——都将以数字形式存储于笔中。你可在笔的存储器中存储多达40页的资料。而对你来说，你只不过是在使用一支普通的笔而已。

只有当你将笔插入与PC机连接的笔座中时，有趣的事才真正开始。你的PC机的专用软件会估算出你所做之事，并下载你最新写下的所有文件。根据你是否在专用记事本的一些特定框里打对号，这种笔还可以辨别出文档是电子邮件、“待执行”人物还是要插入文字处理文档的图表。文档下载后，你就可以查看、打印或将其转换为其他形式。

io私人数字笔可妥善又简单地解决手写笔记的存储、共享和检索问题，也可处理图表、图片以及其他非文本资料。你不必携带电脑，你只需要拿出笔和专门用纸就能开始工作了。

这是一种很了不起的产品，因为你的工作不会因之产生任何麻烦——你不必携带显示屏，也不必携带任何附件。它非常轻便，如果你需要的话，也可以当普通笔来用，而这种专用记事本看起来摸起来都很像普通记事本。有些人会很好奇，不明白为什么你在用雪茄写字，这是唯一看起来令人费解的地方。

io私人数字笔在其他方面也很有潜力。例如，联邦快递公司正引进一种数字笔，从而用户可用手填写表格，而无需再费力劳神地打进机器中。如果数字为数字型，几乎所有事情都可由这种笔来完成——例如将数据通过无线方式或手机传输到中心计算机上。医生可将处方直接转到药房，减少了欺诈行为的发生。警察可将报告发回警察局，减少了文书工作。

之一篇

The Issue of Package

Maybe everyone has such an experience that you have to unwrap several layers of packaging when you enjoy a piece of candy. But this overuse of wrapping is not confined to luxuries. It is becoming increasingly difficult to buy anything that is not done up in beautiful wrapping.

The package itself is of no interest to the shopper, who usually throws it away immediately. So why is it done? Some of it, like the cellophane on meat, is necessary, but most of the rest is simply competitive selling. This is absurd. Packaging is using up scarce energy and resources and messing up the environment.

Recycling is already happening with milk bottles which are returned to the dairies, washed out,and refilled. But both glass and paper are being threatened by the growing use of plastic. More dairies are experimenting with plastic bottles.

The trouble with plastic is that it does not rot. Some environmentalists argue that the only solution to the problem of ever increasing plastic containers is to do away with plastic altogether in the shops, a suggestion unacceptable to many manufacturers who say there is no alternative to their handy plastic packs.

It is evident that more research is needed into the recovery and reuse of various materials and into the cost of collecting and recycling containers as opposed to producing new ones. Unnecessary packaging, intended to be used just once, and make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of doing away with packaging as using it sensibly. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.

31. "This overuse of wrapping is not confined to luxuries. " (Line 2, Paragraph 1) means __________.

A. more wrapping is needed for ordinary products

B. more wrapping is used for luxuries than for ordinary products

C. too much wrapping is used for both luxury and ordinary products

D. the wrapping used for luxury products is unnecessary

32. Packaging is important to manufacturers because __________.

A. it is easy to use it again

B. shoppers are interested in beautiful packaging

C. they want to attract more shoppers

D. packaged things will not go rotten

33. According to the passage, dairies are __________.

A. experimenting with the use of paper bottles

B. giving up the use of glass bottles

C. increasing the use of plastic bottles

D. re-using their paper containers

34. Some environmentalists think that __________.

A. plastic packaging should be made more convenient

B. no alternative can be found to plastic packaging

C. too much plastic is wasted

D. shops should stop using plastic containers

35. The author thinks that

A. packing is actually useless and could be ignored

B.people will soon stop using packaging altogether

C.enough research has been done into recycling

D.it is better to produce new materials than to re—tlSe old ones

Electric Backpack

Backpacks are convenient. They can hold your books, your lunch, and a change of clothes leaving your hands free to do other things. Someday, if you don't mind carrying a heavy load, your backpacks might also power your MP3 player, keep your cell phone running, and maybe even light your way home.

Lawrence C. Rome and his colleagues from the University of Pennsylvania in Philadelphia and the Marine Biological Laboratory in Woods Hole, Mass. have invented a backpack thatmakes electricity from energy produced while its wearer walks. In military actions search-and-rescue operations and scientific field studies, people rely increasingly on cellphones global positioning system (GPS) receivers,night-vision goggles, and other battery powered devices to get around and do their work. The backpack's electricity-generating feature could dramatically reduce the amount of a wearer's load now devoted to spare batteries, report Rome and his colleagues in the Sept.9 science.

The backpack's electricity-creating powers depend on springs used to hang a cloth pack from its metal frame. The frame sits against the wearer's back, and the whole pack moves up and down as the person walks. A gear mechani *** converts vertical movements of the pack to rotary motions of an electrical generator, producing up to 7.4 watts.

Unexpectedly, tests showed that wearers of the new backpack alter their gaits in response to the pack's oscillations, so that they carry loads more comfortably and with less effort than they do ordinary backpacks. Because of that surprising advantage, Rome plans to commercialize both electric and non-electric versions of the backpack.

The backpack could be especially useful for soldiers, scientists, mountaineers, and emergency workers who typically carry heavy backpacks. For the rest of us, power-generating backpacks could make it possible to walk, play video games, watch TV, and listen to music, all at the same time. Electricity-generating packs aren't on the market yet, but if you do get one eventually just make sure to look both ways before crossing the street!

36. Backpacks are convenient because __________.

A o they can be verylarge

B. they can hold as many things as you want to carry

C. your handsare freed to do other things

Do you do not have to carry things withyou

37. What is the most important feature of the backpack invented byLawrence C.Romeand his colleagues?

A. It produces electricity forelectronic devices while the wearer walks.

B. It can be used as cellphones, GPS in the military actions or field studies.

C. It is *** all andconvenient.

D. It is light and easy to carry.

38. The word "'springs" in Paragraph 3 means __________.

A. a *** all stream of water flowing naturally from theearth

B. the season of the year, occurring between winter and summer

C. the act or an instance of jumping or leaping

D. a length of metal woundaround, which returns to its original shape afterbeing pushed

39. According to Paragraph 4, what does Rome plan to do?

A. To make the backpackmore comfortable for the wearer.

B. To put the backpack on the market.

C. To test the advantage of the backpack.

D. To promote the backpack in anewspaper or on television.

40. What is implied in "if you do get oneeventually, just make sure to look bothways before crossing the street!"?

A. You will be too excited to watch the traffic.

B. Enjoyingelectronic devices while walking may invite traffic accidents.

C. It is notpossible for you to get such a backpack.

D. It is wise of you to have such abackpack.

Invisibility Ring

Scientists can't yet make an invisibility cloak like the one that Harry Potter uses. But, for the first time, they've constructed a simple cloaking device that makes itself and something placed inside it invisible to microwaves.

When a person "sees" an object, his or her eye senses many different waves of visible light as they bounce off the object. The eye and brain then work together to organize the sensations and reconstruct the object's original shape. So, to make an object invisible, scientists have to keep waves from bouncing off it. And they have to make sure the object casts no shadow. Otherwise, the absence of reflected light on one side would give the object away.

Invisibility isn't possible yet with waves of light that the human eye can see. But it is now possible with microwaves. Like visible light, microwaves are a form of radiant energy. They are part of the electromagnetic spectrum, which also includes radio waves, infrared light, ultravioletmys, X rays, and gamma rays. The wave lengths of microwaves are shorter than those of radio waves but longer than those of visible light.

The scientists' new "invisibility device" is the size of a drink coaster and shaped likearing. The ring is made of a special material with unusual ability. When microwaves strike thering, very few bounce off it. Instead, they pass through the ring, which bends the waves all the way around until they reach the opposite side. The waves then return to their original paths.

To a detector set up to receive microwaves on the other side of the ring, it looks as if the waves never changed their paths as if there were no object in the way! So, the ring is effectively invisible.

When the researchers put a *** all copper loop inside the ring, it, too, is nearly invisible.

However, the cloaking device and anything inside it do cast a pale shadow. And the device works only for microwaves, not for visible light or any kind of electromagnetic radiation. So, Harry Potter's invisibility cloak doesn't have any real competition yet.

41. Harry Potter is mentioned in the passage, because scientists __________.

A. can now make an invisible cloak of the same kind as he uses

B. try to make an invisible cloak of the same kind as he uses

C. try to invent a device similar in idea to the invisible cloak he uses

D. know that it is possible to make an invisible cloak of the same kind

42. What is true of microwaves?

A. Their wavelengths are shorter than those of visible light.

B. Their wavelengths are longer than those of visible light.

C. They are different from visible light as they are a kind of radiant energy.

D. They are visible to the human eye.

43. What is NOT true of the invisibility device?

A. It is made of a special material with unusual ability.

B. Microwaves bounce off it when they strike it.

C. Microwaves pass through it when they strike it.

D. It bends the microwaves all the way around until they reach the opposite side.

44. What does the word "coaster" mean in the passage?

A. A disk or plate placed under a drinking glass to protect a table top.

B. A vessel engaged in coastal trade.

C. A roller coaster.

D. A resident of a coastal area.

45. Harry Potter's invisibility cloak doesn't have any real competition yet, because __________.

A. scientists have not found out how his cloak works

B. the cloaking device is a total failure

C. the cloaking device works only for microwaves

D. the cloaking device works only for visible light
