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(升级) 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(安装)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.

As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without many living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight. Very often the effects of pollution are not noticed for many months or years because the first organisms (生物体) to be affected are either plants or plankton (浮游生物). These organisms are the food of fish, birds, and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it is not until dead fish and water birds are seen at the river’s edge or on the sea shore that people realize what is happening.
Where do the substances which pollute water come from? There are two main sources, sewage(污水) and industrial waste. As more detergent (洗涤剂)is used in homes, more of it is finally put into our rivers, lakes and seas. Detergents harm water birds by breaking down the natural substances which keep their feathers waterproof. Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful since there are many highly poisonous materials in it, such as copper and lead.
So if we want to stop this pollution, the answer is simple. Sewage and industrial waste must be made clean before flowing into the water reservoirs. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
【小题1】Pollution in water is noticed ________.
A.when the first organisms are affected |
B.when many fish and birds die |
C.when poisons are poured into water |
D.As soon as the balance of nature is destroyed |
A.water | B.fish | C.Poison | D.oxygen |
A.full of water | B.not allowing water to go through |
C.covered with water | D.cleaned by water |
A.Industrial waste and chemicals | B.Water in the river |
C.Coal and wood | D.plastic |

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 (玻璃纸) 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 (牛奶场), 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.
【小题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 |
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. |
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 |
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 |

Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. researchers reported on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may beprotected against diseases such as Alzheimer’s(早老痴呆症). University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy(怀孕) are protecting the brain, including estrogen(雌激素),which we know has many neuroprotective (保护神经的) effects,” Kinsley said. “It’s rat data but humans are mammals just like these animals are mammals,” he added in a telephone interview. “They go through pregnancy and hormonal changes.”Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age-related brain decline.
“When people think about pregnancy, they think about what happens to babies and the mother from the neck down,”said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida.“They do not realize that hormones are washing on the brain. If you look at female animals who have never gone through pregnancy, they act differently toward young. But if she goes through pregnancy, she will sacrifice her life for her infant—that is a great change in her behavior that showed in genetic alterations(改变) to the brain.”
【小题1】How do scientists know “Motherhood may make women smarter”?
A.Some researchers have told them. |
B.Many women say so. |
C.They know it by experimenting on rats. |

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.
【小题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 |
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 |
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 |

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(缝合) 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(脚踏板) 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(版税). In the end, Howe became a millionaire, not by manufacturing the sewing machine, but by receiving royalty payments for his invention.
【小题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 |
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. |
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. |
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 |

Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people of your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging (抗衰老的) treatment. Now, all three of you look the same age!
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles (粒子) much smaller than the cells in your body. The particles can be programmed to change clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk, and it knows the milk is old. In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve. Such “smart technology” is all around you.
So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli, “it has to be so much better that it replaces what we have already.” The Internet is one example. What will be the next?

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(归属) 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.
【小题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. |
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. |
A.Textbooks. | B.Advertisements. | C.Instructions. | D.Magazines. |
A.an argumentative writing | B.a feature story |
C.a dog show review | D.a research result |

A portable lung which could help those with breathing problems lead a normal life is being developed by scientists.
The Swansea University scientists say it could take many years before the device(装置) , the size of a spectacle box (眼镜盒) , is available . Lung patients , who have seen how it would work , have welcomed the research.
Its research suggests that one person in every seven in the UK is affected by lung disease---- this equates to approximately 8 million people. As of 6 March 2009, 217 people were on the waiting list for a lung transplant(移植) according to figures by NHS Blood and Transplant .
Now scientists in Swansea are developing a portable artificial lung which could transform (改观) the lives of patients . Researchers claim that in the long term the device could offer an alternative to lung transplant , giving hope to those who suffer from conditions such as emphysema(肺气肿) and cystic fibrosis.
The device mimics the function of a lung---by getting oxygen into and carbon dioxide out of the blood stream . Professor Bill Johns came up with the idea after his son died of Cystic Fibrosis . It is important that we make something that will help people , who instead of being confined (局限) to a wheelchair with an oxygen bottle , can actually walk around and do things for themselves , he said.
Although the research has been welcomed by leading charities(慈善) , caution has also been voiced over the length of time it will take before a portable lung will become available .
“We have to stress that this is several years away from being used , even in a trial stage,” said Chris Mulholland , head of the British Lung Foundation.
Patient Elizabeth Spence from Swansea has been refused the double lung transplant she needs but remains hopeful that one day the new device could save her . “ My body will reject the lungs , so this possibly could be an answer--- another way of getting new lungs without actually having the transplant,” she said.
【小题1】Which of the following about the portable lung would the author agree?
A.It can help a lot in lung transplants |
B.It was once on display |
C.It works differently from the normal one in the body |
D.It’s just like an oxygen bottle. |
A.support | B.money | C.time | D.trial |
A.Negative. | B.Doubtful. | C.Curious. | D.Objective. |
A.Science. | B.Culture. | C.Economy. | D.Education. |
