More than 2.25 billion cups of coffee are consumed across the globe each day, and it’s likely that many taste bitter.
Now, a new study suggests that coffee fans can make their drink taste sweeter by simply changing the color of their cups.
Scientists claim that blue and glass mugs, which are popular in some coffee shops, can reduce coffee’s bitterness, without any need for sugar, and that coffee drunk from white cups tastes the bitterest.
To prove their claims, the researchers invited 36 volunteers and used three different colored cups— blue, white and transparent glass—to do an experiment.
In the experiment, coffee consumed from the white cup was found to taste less sweet when compared to the other two colored cups, while the blue cup made the coffee taste the sweetest.
The scientists believe that the color brown may be associated with coffee’s bitterness because coffee in a white cup appears the brownest and tastes the bitterest.
“Our study clearly shows that the color of a coffee cup does influence the perceived (感受到的) taste and flavor of coffee,” said Dr George Doorn of Federation University Australia, “but the potential effects may be different between a one-time purchase and a return customer.”
“Anyhow, the effect of the color of the cup on the flavor of the coffee suggests that café owners, baristas (服务员), as well as coffee cup manufacturers should carefully consider the color of their cups, ” he added.
However, the idea that color can alter the taste of food and drink is not new.
A study published last year revealed that red, strawberry-flavored mousse (慕斯蛋糕) served on a white plate was rated as 10 percent sweeter and 15 percent more flavorous than the same food presented on a black plate. What color of the cup can best reduce coffee’s bitterness without adding sugar?
| A．Blue. | B．Brown. | C．White. | D．Transparent. |
The scientists used ________ to do the experiment to prove their claims.
① different brands of coffee
② different colored coffee cups
③ several volunteers
④ several manufactures
| A．①② | B．②③ | C．②④ | D．③④ |
Why does coffee in white cups taste the least sweet?
| A．Because white cups are not as beautiful as other cups. |
| B．Because white cups make coffee appear the brownest. |
| C．Because white cups reduce the sugar in them. |
| D．Because white cups are better used to serve cakes. |
According to the article, which of the following statements is TRUE?
| A．Black plates increase the sweetness of food and drink. |
| B．Strawberry-flavored mousse is 10 percent sweeter than coffee. |
| C．People consume more than 2.5 billion cups of coffee across the globe every year. |
| D．People can make coffee taste sweeter by changing the color of their coffee cups. |
Hikosaburo Yasuda of Nakano, Japan, plans to buy an iPad to keep up with junior members in his computer club．"It's
important to always try new things, otherwise you get left behind," he says． 
Yasuda is 95 years old．He and his colleagues, looking for easier ways to search the Web and send e-mail, represent a potential market for Apple （AAPL）'s iPad．The company has sold 3．27 million iPads since its launch in April, 
but doesn't break down sales figures by customer age, making it impossible to know with certainty how many seniors are buying them．However, anecdotal evidence suggests it's a hit with the elderly．
The iPad's intuitive interface （直观界面） makes it appealing to senior citizens around the world, says Takahiro Miura, a researcher at the University of Tokyo: "The iPad is a good tool for the elderly because it's very forgiving of mistakes．" Miura's team uses computers to help train senior citizens to rejoin the workforce．"Unlike the PC, it doesn't require previous knowledge," he says．
James Cordwell, a technology analyst at Atlantic-Equities in London, says the iPad's popularity with the elderly is helping Apple reach beyond its traditional base of younger customer. “The world’s population, especially in developed markets, is getting older, and it’s probably a market where Apple has least entered,” Cordwell says. Elderly users are “a key source of growth for them in the future.”
The elderly in Japan, who make up an estimated 22 percent of the population, may prove particularly receptive to the iPad. They spend more than any other group in the country except for those under 30, according to a report by Japan's Cabinet Office. Motoo Kitamura, 78, a former gas salesman, bought an iPad to help him communicate with his 2-year-old grandson and stave off dementia. "Trying new things like that is a good mental exercise," he says. The underlined part “a hit” in Paragraph 2 may probably mean “ ”.
| A．a hard strike | B．a heavy burden | C．quite popular | D．very familiar |
Which of the following is NOT an advantage of the iPad over the PC?
| A．It has intuitive interface. | B．It is easier to operate. |
| C．It is more accessible to beginners. | D．It is a good mental exercise. |
What can we learn from the passage?
| A．The people under thirty are the largest consumers in Japan except for the elderly. |
| B．The traditional customers of AAPL’s products are usually the yong. |
| C．The elderly will soon grow into the largest customer group in place of the young. |
| D．The elderly in Japan have great enthusiasm for latest hi – tech products. |
What could be the best title for the passage?
| A．The iPad leads Apple to the elderly |
| B．Ipad hits Japan’s store shelves |
| C．Ipad’s arrival in Tokyo causes Uapanese to reflect |
| D．AAPL attempts to balance the old and the yong |
It s just a small, white envelope stuck among the branches of our Christmas tree．It has been there for the past 10 years or so．It all began because my husband Mike hated Christmas—the commercial aspects of Christmas-overspending．Knowing he felt this way, I decided one year to avoid the usual presents．The idea came in an unusual way．
Our son Kevin, who was 12 that year, was wrestling at the junior level at the school he attended; and shortly before Christmas, there was a match against a team sponsored by a church．These youngsters, dressed in ragged clothes, presenting a sharp contrast to our boys in their beautiful dresses and shoes．As the match began, I was alarmed to see that the other team was wrestling without headgear, a kind of light helmet designed to protect a wrestler's ears．It was a luxury that the poor team obviously could not afford．Well, we ended up defeating them．Mike, seated beside me, shook his head sadly, "
I wish just one of them could have won," he said．"They have a lot of potential, but losing like this could take the heart right out of them．" That's when the idea for his present came．That afternoon, I went to a local sporting goods store and bought wrestling headgear and shoes for the youngsters and sent them anonymously （匿名地） to the church．On Christmas Eve? I placed the envelope on the tree, the note inside telling Mike what I had done and that this was his gift from me．His smile was the brightest thing about Christmas that year and in the following years．
For each Christmas, I followed the tradition．The envelope became the highlight of our Christmas．It was always the last thing opened on Christmas morning and our children, ignoring their new toys, would stand with wide-eyed expectation as their dad lifted the envelope from the tree to show its contents．As the children grew, they joined．
May we all remember the reason for Christmas, and the true Christmas spirit this year and always．God bless梡ass this along to your friends and loved ones．The author avoids usual Christmas presents because her husband _____．
| A．likes cheap Christmas presents |

Family quarrels and lack of free time can promote headaches in children. This is what Jennifer Gassmann and her partners have concluded in a study that appears in the current issue of the Deutsches Arzteblatt International. This study was a component of a large-scale study entitled “Children, Adolescents, and Headaches”, in which data were collected in four annual “waves” from 2003 to 2006.
Up to 30% of children around the world complain of headaches at least once a week. Out of a variety of possible factors tested in a larger study, the authors chose to look at the ones related to the children’s family and leisure time.
According to the study, boys who experience more than one family quarrel per week have a 1.8 times higher risk of developing headaches. The amount of free time available to them seems to be even more important: boys who seldom have time to themselves have a 2.1 times higher risk of developing headaches.
The behavior of parents when children complain of headaches also seems to play a major role. Both positive and negative responses from parents teach children that they can gain advantages from headaches. These responses have a particularly strong effect on the frequency of symptoms in girls, with supportive responses raising the risk of recurrent(周期性的) headaches by 25%.
The genders also differed with respect to headache frequency. Twice as many girls as boys had their symptoms at least once a week. The ages of the children, however, seemed to have no more than a minor effect on their headaches.
The study may become a reminder for parents, especially for those unpeaceful families.

Could you stand the noise of a street-sweeper truck going up and down the street outside of your house three times a week at 4 a.m.? The noise —described by Blomberg as “loud as a NASCAR(全国赛车联合会) race car but at a speed of 5 miles per hour” — annoyed him so much that he tried to persuade the city to reschedule street sweeping to begin at 6 a.m. He also founded the nonprofit Noise Pollution Clearinghouse, an organization that provides research and information to others whose request for quiet might otherwise fall on deaf ears.
Hearing loss, in fact, is the most obvious medical consequence of noise pollution, but it is hardly the only one, explains environmental psychologist Arline Bronaft. In her research, Bronzaft found that constant noise exposure could reduce children’s learning ability and cognitive(认知的) development. Beyond all that, regularly, “you’ve got to take a break from sound,” says Bronzaft.
The bad news, says Blomberg, is that “the last century was the noisiest in history.” The good news, he continues, is that the greener we get, the quieter we’ll also get. Electric cars and lawn equipment, for instance, make less noise, just as more fuel-efficient vehicles do. Improved technology can also provide measures to make the problem less serious. Fire engines and police cars could replace those loud sirens(警报器) with other models; and you can turn down the volume inside your home by replacing noisy household appliances with quieter, energy-saving models.
“ I don’t think you can name a noise source that I can’t find a way to make quieter,” says Blomberg. But the real challenge is to change people’s attitudes. “ In the 1960s, we made it unacceptable to throw litter out of the window of your car,” he says. Today it’s time to recognize that “noise is to the soundscape as litter is to the landscape.” The goal is to “create a culture where you do not throw your aural (听觉的) litter out of the window.
64. What do we know about the Noise Pollution Clearinghouse?
A. It was founded by the city leaders.
B. It was supported by NASCSR.
C. It can rearrange the time of street sweeping.
D. It aims to help those who want more peace and quiet.
65. Which of the following makes the most noise?
A. Electric cars. B. Loud sirens. C. Lawn equipment. D. Police cars.

A. it’s impossible to make a noise-maker quieter
B. it’s difficult to quiet people down
C. in the 1960s, throwing “sound” out of the window was forbidden
D. street sweeping should be stopped forever
67. Which of the following is the best title for the passage?
A. Reducing Noise Pollution B. Children’s Mental Development
C. Vehicles that Make Less Noise D. Forbidding Throwing Litter
What’s that smell? Do you hear that noise? Taste this! Look at me! Feel this, isn’t it soft? When you hear, or even use these phrases, you probably don’t stop to think about why we use them. Well, it’s because of our senses. Without us even knowing, our sense organs (nose, eyes, ears, tongue, and skin) are taking in information and sending it to the brain for processing. If we didn’t have them, we would not be able to smell, see, hear, taste, or touch anything!
Senses are the physical means by which all living things see, hear, smell, taste, and touch. Each sense collects information about the world and detects changes within the body. Both people and animals get all of their knowledge from their senses, and that is why senses are so important.
All senses depend on the working nerve system. Our sense organs start to work when something stimulates（刺激） special nerve cells, called receptors, in a sense organ. Once stimulated, the receptors send nerve impulses along sensory nerves to the brain. Your brain then tells you what to do. For example, your sound receptors are often attacked by billions of sound waves. When these signals reach the part of the brain called the cerebral cortex（大脑皮层）, we become conscious of the sounds.
Our group really learned a lot about the senses while creating this website. We hope that you are able to get just as much out of it. Please feel free to comment about anything on the site by e-mailing us. Also, don’t forget to sign the guest book! Thanks for visiting our site. Come back soon!
