With the popularity of 3D movies over the past several years , there was no doubt that the technology would make its way into our homes, The question is: Is it really a technology that is going to stay with us , thus deserving an upgrade(升級) at this time?
Many families have recently bought a new TV set, and the idea of changing it just to take advantage of a technology in its infancy(初期)will put many people off the idea. Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time.
Another issue is that the glasses are expensive as well as complicated, and have also been known to cause headaches, none of which makes for a pleasant experience.
While manufacturers are working towards glasses-free technology, it just isn’t here yet, and it could be several years before it is commercially successful. That is one of main things that will keep 3D completely in the “fashion” zone for the time being . If the television manufacturers are willing to hold onto the idea until glasses-free choices are available—and they can reach a higher installed(安裝)user base—this might very well catch on. Everyone needs to remember, however, that these are businesses, and they are in it to make money. If 3D isn’t selling at the rate they are comfortable with, then they will dump it and move on to the next thing.
Many homes are filled with products that didn’t catch on rapidly and companies ended up leaving them with no support. Do you have an HD DVD player? Remember how the MiniDisc was supposed to replace the CD? For now, it’s easy to see how 3D televisions could join this list of technologies.
There is one upside to the 3D television problem: They have beautiful 2D images. Even if 3D goes away, you still have a great –looking screen and beautiful images. If you are in the market for a new TV and you can afford to drop the couple extra hundred dollars to buy one, you can view it as guaranteeing your purchase in case the technology proves to be effective.
小題1:We know from the text that 3D TV .

A．is easy to operate

B．has been fully developed

C．has many products attached to it

D．has already replaced normal TV sets

小題2:What’s the main idea of paragraph 4?

A．3D is fashionable and expensive.

B．It’s hard for 3D to be commercially successful.

C．Television manufacturers’ only purpose is to make money.

D．It’s impossible to create glasses-free technology at the moment.

小題3:The examples of the HD DVD player and CD are to show .

A．they are not necessary

B．they are bound to be replaced

C．3D TV might not be here to stay

D．3D technology needs improving

小題4:The underlined word “upside” in the last paragraph probably means .

A．solution

B．exception

C．character

D．benefit

小題5:What’s the author’s opinion on 3D TV?
A.He is critical of it.
B. He thinks highly of it.
C.It is more effective than expected.
D. It has more beautiful images than 2D.

小題1:C
小題2:D
小題3:C
小題4:D
小題5:A

試題分析：
【文章大意】本文是一篇說明文。文章講述了3D電視的發展前景及其一些弊端。
小題1:C考查推理判斷。根據文章第二段中的Then there are the additional costs that come along with a 3Dset from needing to get a Blu-ray player that can process the signal to purchasing enough glasses for the entire family to be able to watch a program at the same time.可知，3D電視還需要許多附帶的產品才能滿足人們的需要，故選C。
小題2:D考查主旨要義。根據文章第四段中的While manufacturers are working towards glasses-free technology, it just isn’t here yet, and it could be several years before it is commercially successful.可知，這是主題句。這表明目前3D眼睛技術免費還不可能，因為幾年之后才能交易成功。故選D。
小題3:C考查細節理解。根據文章第五段中的For now, it’s easy to see how 3D televisions could join this list of technologies.可知，它很快也就被加入淘汰的技術名單中。這說明3D技術不會停留太久。故選C。
小題4:D考查猜測詞義。根據文章最后一段中的They have beautiful 2D images. Even if 3D goes away, you still have a great –looking screen and beautiful images.可知，本段講述3D電視的好處，如果3D不成，還有2D美麗的圖像。所以由此推知，其意為：好處。故選D。
小題5:A考查作者的看法。根據文章的整體內容可知，作者第一段發問對3D質疑，接下來說附帶產品太多，可能這種技術很快消失。所以作者持批評態度。故選A。

Full face transplants are no longer science fiction fantasy, a leading surgeon has said, adding that they are technically practical but ethically（道德地）complex.
Peter Butler from London’s Royal Free Hospital called for a debate on the ethics of such an operation made possible by new drugs which stop the body’s immune (免疫）system rejecting a transplanted face. “It is not ‘can you do it?’ but ‘should we do it?’” he told the BBC. “The technical part is not complex, but I don’t think that’s going to be the very great difficulty. The ethical and moral debate is obviously going to have to take place before the first facial transplantation.”
The British Association of Plastic Surgeons will discuss the microsurgical procedure (微型外科技術), which could give new skin, bone, nose, chin, lips and ears from deceased donors to patients disfigured（毀容的）by accidents, burns or cancer. But surgeons could have trouble finding enough willing donors. Butler said his survey of doctors, nurses and members of the public showed most would accept a face transplant but few were willing to donate their own after dying.
Despite a number of ethical concerns, Christine Piff, who founded the charity Let’s Face It after suffering a rare facial cancer 25 years ago, welcomed the possibility of face transplants. She rejected the idea that the procedure would mean people would end up living with a dead person’s face. “There are so many people without faces, I have half a face… but we are all so much more than just a face… you don’t take on their personality. You are still you,” she told reporters. “If we can donate other organs of the body then why not the face. I can’t see anything wrong with it.”
小題1:The underlined word “deceased” in the third paragraph probably means _________.

A．living

B．dead

C．diseased

D．dying

小題2: When Christine Piff says “There are so many people without faces…”, she refers to the people _________.

A．who are dishonorable and shameless

B．who disagree with the full face transplant

C．who are seriously injured by an accident

D．who are disfigured by accidents, burns and cancer

小題3:According to the passage, what makes it likely to carry out a facial transplantation?

A．Drugs are available to stop the body’s immune system rejecting a transplanted face.

B．There are some people who are willing to donate their faces after dying.

C．Most people accept the idea of face transplants.

D．It’s morally practical, though technically complex.

小題4:What is implied but not stated in the passage?

A．Christine Piff has been the first lucky patient to receive a face transplant.

B．Surgeons have difficulty finding enough willing donors.

C．The main difficulty with the operation lies in the matter of ethics and morality.

D．Nobody other than Christine Piff is quite in favor of the donation of organs.

小題5:What would be the best title for the text?

A．First Facial Transplantation

B．Debate on the Ethics of Transplant

C．Face Transplant No Longer Science Fantasy

D．Let’s Face It

Have you dreamed of building your own machine? Do you wish you could invent something new? Here we look at a few British inventions of recent times.
Adaptable glasses
Do you wear glasses? If so, can you imagine life without them? In 1985, Joshua Silver, a professor at Oxford University, asked himself, “Can I invent a pair of glasses that could be changed by the wearer?” He designed two plastic lenses（透鏡）that are filled with a special liquid. Using syringes（注射器）you change the liquid between the lenses until you can see clearly. The glasses are not beautiful but they are easy to use and cheap to make.
The wind-up radio
When you switch your TV on tonight, think about all those people without electricity. Thinking about this, Trevor Baylis came up with the idea of designing a radio that could be powered by hand. In common with Joshua Silver he wanted his invention to be cheap and easy to use. He wanted even the poorest people in developing countries, who don’t have electricity and cannot afford batteries, to use it. The radio has a generator (發電機) which is powered by turning a handle. In 1996 it won a BBC Design Award for Best Protect and Best Design.
The Dyson cleaner
In many homes around the world you can see a cleaner that looks like a spaceship. This is the Dyson vacuum (真空) cleaner which uses something called “cyclonic separation” to separate the dirt. You do not need a bag for your cleaner and it does not get blocked so it is very practical. The idea came to Sir James Dyson after he kept having problems with his vacuum cleaner. He decided he could design a better one and in 1993 he opened his own factory. The Dyson is now one of the best-selling cleaners in the UK and Dyson is believed to have earned over a billion pounds.
The Zapata fly-board
Ever dreamed of zooming through the water and leaping in the air like a dolphin? Now you can thanks to a fly-board, built by water sports enthusiast Frank Zapata. With it you can dive back in the water and out again. It’s possible to jump to incredible heights out of the water — over 30 feet. The basic fly-board model comes in at ￡4,200.
So keep dreaming and inventing. One day you might get it right.
小題1:What can we learn about Adaptable glasses?

A．They are very expensive.	B．The inventor is a student.
C．The glasses are fragile.	D．They don’t look very nice.

小題2:Which invention won an award?

A．Adaptable glasses.	B．The wind-up radio.
C．The Dyson cleaner.	D．The Zapata fly-board.

小題3:The Dyson cleaner was invented with the purpose of _________.

A．helping people use cleaners more easily

B．making Dyson a rich businessman

C．keeping the house cleaner than before

D．taking the place of human cleaners

To get a chocolate out of a box requires a lot of unpacking: the box has to be taken out of the paper bag in which it arrived, the cellophane (玻璃紙) wrapper has to be torn off, the lid opened and the paper removed, the chocolate itself then has to be unwrapped from its own piece of paper. But this overuse of wrapping is not limited to luxuries. It is now 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. Useless wrapping accounts for much of the refuse put out by the average London house-hold each week. 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 valuable energy and resources and polluting the environment.
Recycling is already happening with milk bottles which are returned to the dairies (牛奶場）, 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 throw away plastic altogether in the shops, a suggestion unacceptable to many producers who say there is no alternative (替代品) to their handy plastic packs.
It is evident that more research is needed into the recovery and re-use of various materials and into the cost of collecting and recycling containers rather than producing new ones. Unnecessary packaging, intended to be used just once, and to make things look better so more people will buy them, is clearly becoming increasingly absurd. But it is not so much a question of throwing away packaging as using it wisely. What is needed now is a more advanced approach to using scarce resources for what is, after all, a relatively unimportant function.
小題1:The underlined part “this overuse of wrapping is not limited to luxuries” in Paragraph l means ______.

A．more wrapping is needed for ordinary products

B．the wrapping used for luxury products is unnecessary

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

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

小題2:Why is packaging important to producers?

A．It is easy to use it again.

B．Packaged things will not go rotten.

C．They want to attract more shoppers.

D．Shoppers are all interested in beautiful packaging.

小題3:According to the passage, dairies are ______.

A．reusing their paper containers

B．giving up the use of glass bottles

C．increasing the use of plastic bottles

D．experimenting with the use of paper bottles

小題4:Some environmentalists think that ______.

A．too much plastic is wasted

B．shops should stop using plastic containers

C．no alternative can be found to plastic packaging

D．plastic packaging should be made more convenient

Unknown to most Facebook users, the social network actually offers a lot of privacy controls and security features which can help you lock your account, so you can speak freely. If it’s used properly, you’ll never have to worry about whether you will have to “friend” your boss or your mom. You can friend anyone you want while staying comfortable in the knowledge that not everyone gets to see everything you post.
The problem with carrying out these privacy options is that they’re just too confusing for most non-tech clever people to handle. And often, most people don’t want to bother to take the time to learn. To simplify the process, we’re offering one easy step you can take today to help make your Facebook experience safer, more secure, and more private.
Just make “Friend Lists”. Yes, it will take some time, especially if you’re connected to a couple of hundred friends already. But this step, while not the quickest, is fairly simple. And it will be one of the most useful things you can do on Facebook.
Friend lists, as the name suggests, are lists for classifying your friends into various groups. The nice thing about this feature is that once you set these lists up, you won’t have to do it again. We suggest that you put your work colleagues and professional acquaintances into a friend list named “Work”, personal friends you’re not very close with into a list called “Acquaintances”, and people you’re related to into a list called “Family”. Those three main categories will separate out the groups of “friends” who you may want to hide some information from.
To create a friend list, click on “Friends” at the top of the Facebook homepage. In the left-hand column, click “Friends” again under the “Lists” section. Now you’ll see a button at the top that says “Create New List”. Click it. In the pop-up that appears, you can name your list and pick members. If you’ve ever shared an application with your friends, the process of doing this will be very familiar.
When you’ve finished making lists, you’ll be able to use them when selecting who can see what (or who can’t!) when configuring (配置) the security settings described below.
小題1:What function isn’t understood by most people on Facebook?

A．Surfing the Internet.

B．Setting safety protection.

C．Sharing personal information.

D．Making foreign friends.

小題2:What can we learn about Facebook according to the text?

A．Its process of privacy-setting is too complex.

B．It displays everything people post.

C．It lacks privacy controls and security features.

D．Its post is designed for technical people.

小題3:What advantage can we get from making friend lists?

A．We can avoid our bosses adding us as friends.

B．We can share applications with friends.

C．We can separate acquaintances from family.

D．We can hide different information from different friends.

We are fortunate to be living in a time when all people have the ability to access any knowledge they desire. This digital society that we live in affords us opportunities that our ancestor only dreamed of having. We should not take this privilege for granted.
In the not so distant past of the 1950s, people who wanted to research an idea, a product, or anything else, had to go to a library where they could look up information in books. Not all people had the same access to the books, and the information they contained. In America, if your skin was black, you could not use the same library that a person with white skin used. If a black skinned person was allowed access to a library, it most likely was stocked with outdated books that white skinned people had discarded.
In the digital society we live in today, the color of your skin does not determine the access you have to information. Technology has brought to us the powerful tools like the Internet where we can find information on almost every subject.
Access to the Internet has allowed us to research the things we are planning to purchase. We are capable of comparing prices on things like insurance, appliances, entertainment, clothing, and all other things. We also now have the ability to purchase items online without ever leaving our homes. We have been freed from the restrictions of store hours, and regional sales. A person in America can purchase a product from a person in Germany, without leaving home.
Because of the digital society we live in our children can learn about anything they are interested in. When they ask you what the dinosaurs ate, you can look it up, and tell them the answer. Because of this people will be smarter in the future, and technology will only improve.
小題1:By “We should not take this privilege for granted”, the writer means that ______.

A．we have special right to do anything

B．it is wrong to make use of the privilege

C．knowledge is important in the digital society

D．we should seize the chances the modern society offers

小題2:The main idea of the fourth paragraph is that ______.

A．the Internet brings us a lot of convenience

B．people in modern society are mostly wealthy

C．we would like to stay at home every day

D．we can find anything we like in the world

小題3:The dinosaurs are mentioned in the last paragraph in order to tell us that _____.

A．people will be much clever than ever

B．what the dinosaurs ate seems strange to us

C．finding out what the dinosaurs looked like is easy

D．we can learn knowledge with the help of technology

小題4:The writer’s attitude toward the digital society is ______.

A．critical

B．positive

C．neutral

D．negative

Humans have sewn by hand for thousands of years. It was said that the first thread was made from animal muscle and sinew. And the earliest needles were made from bones. Since those early days, many people have been involved in the process of developing a machine that could do the same thing more quickly and with greater efficiency.
Charles Wiesenthal, who was born in Germany, designed and received a patent on a double-pointed needle that eliminated the need to turn the needle around with each stitch(縫合) in England in 1755. Other inventors of that time tried to develop a functional sewing machine, but each design had at least one serious imperfection.
Frenchman Barthelemy Thimonnier finally engineered a machine that really worked. However, he was nearly killed by a group of angry tailors when they burned down his garment factory. They feared that they would lose their jobs to the machine.
American inventor Elias Howe, born on July 9, 1819, was awarded a patent for a method of sewing that used thread from two different sources. Howe’s machine had a needle with an eye at the point, and it used the two threads to make a special stitch called a lockstitch. However, Howe faced difficulty in finding buyers for his machines in America. In frustration, he traveled to England to try to sell his invention there. When he finally returned home, he found that dozens of manufacturers were adapting his discovery for use in their own sewing machines.
Isaac Singer, another American inventor, was also a manufacturer who made improvements to the design of sewing machines. He invented an up-and-down-motion mechanism that replaced the side-to-side machines. He also developed a foot treadle(腳踏板) to power his machine. This improvement left the sewer’s hands free. Undoubtedly, it was a huge improvement of the hand-cranked machine of the past. Soon the Singer sewing machine achieved more fame than the others for it was more practical, it could be adapted to home use and it could be bought on hire-purchase. The Singer sewing machine became the first home appliance, and the Singer company became one of the first American multinationals.
However, Singer used the same method to create a lockstitch that Howe had already patented. As a result, Howe accused him of patent infringement（侵犯）. Of course, Elias Howe won the court case, and Singer was ordered to pay Howe royalties（版稅）. In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
小題1:Barthelemy Thimonnier’s garment factory was burned down because _____________.

A．people did not know how to put out the fire

B．Elias Howe thought Thimonnier had stolen his invention

C．the sewing machines was couldn’t work finally

D．workers who feared the loss of their jobs to a machine set fire

小題2:Which of the following is NOT TRUE according to the passage?

A．Singer is an American inventor and manufacturer.

B．The Singer sewing company became more practical.

C．The foot treadle helped to make the sewer’s hands free.

D．Singer made improvements to the design of sewing machines.

小題3:Why did the court force Isaac Singer to pay Elisa Howe a lifetime of royalties?

A．Because the judge was against Singer for his surly attitude.

B．Because Howe had already patented the lockstitch used by Singer.

C．Because Singer had borrowed money from Howe and never repaid it.

D．Because Singer and Howe had both invented the same machine.

小題4:Which of the following would be the best title for this passage?

A．Stitch in Time Saves Nine

B．The Case between Howe and Singer

C．Patent Laws on the Sewing Machine

D．The Early History of the Sewing Machine

Dogs can know the meaning of a human perspective, say researchers.
Dogs are more capable of understanding situations from a human's point of view than has previously been recognized, according to researchers.
They found dogs were four times more likely to steal food they had been forbidden, when lights were turned off so humans in the room could not see.
This suggested the dogs were able to alter their behavior when they knew their owners' perspective had changed.
The study, published in Animal Cognition, conducted tests on eighty-four dogs.
The experiments had been trying to find whether dogs could make their behavior suitable to react to the changed circumstances of their human owners. It wanted to see if dogs had a "flexible understanding" that could show they understood the viewpoint of a human.
It found that when the lights were turned off, dogs in a room with their human owners were much more likely to disobey and steal forbidden food.
The study says it is "unlikely that the dogs simply forgot that the human was in the room" when there was no light. Instead it seems as though the dogs were able to differentiate between when the human was unable or able to see them.
Juliane Kaminski carried out the research into how dogs are influenced by human circumstances.
Dr Juliane Kaminski, from the University of Portsmouth's psychology department, said the study was "incredible because it implies dogs understand the human can't see them, meaning they might understand the human perspective".
Previous studies have suggested that although humans might think that they can recognize different expressions on their dogs' faces, this is often inaccurate and a projection of human emotions.
“Humans constantly attribute(歸屬) certain qualities and emotions to other living things. We know that our own dog is clever or sensitive, but that's us thinking, not them,” said Dr Kaminski.
“These results suggest humans might be right, where dogs are concerned, but we still can't be completely sure if the results mean dogs have a truly flexible understanding of the mind and others' minds. It has always been assumed only humans had this ability.
小題1:According to the passage, which of the following is TRUE?

A．The researchers made the test on dogs in eighty-four countries.

B．Dogs always obey and don’t steal forbidden food.

C．Dogs may adapt their behavior in response to the changed circumstances.

D．The research is carried out to find out how dogs are influenced by light.

小題2:Which of the following can best serve as the title of the passage?

A．Dogs---Our Loyal Companions Understand Us Most.

B．Dogs Are Our Best Friends.

C．Dogs Can Understand Us In a Way, Researchers Say.

D．Dogs Have Certain Qualities and Emotions of Human Beings, Researchers Say.

小題3:Where can we probably read this kind of articles?

A．Textbooks.

B．Advertisements.

D．Magazines.
