How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.
The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection.
The toothbrush will be able to teach you to brush right (don’t forget the insides of the teeth!) and make sure you’re brushing long enough. “It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.
The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun,” Several says.
Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes,” but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed.
The company says the Kolibree will go on sale this summer, for $99 to $199, developing on features. The U.S. is the first target market.
Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush. Which is one of the feature of the Kolibree toothbrush?
| A．It can sense how users brush their teeth. |
| B．It can track users’school performance. |
| C．It can detect users’fear of seeing a dentist. |

When scientists accidentally killed what turned out to be the world’s oldest living creature, it was bad enough. Now, their mistake has been worsened after further research found it was even older – at 507 years.
The ocean quahog, a type of deep-sea clam, was dredged (捕捞) alive from the bottom of the North Atlantic near Iceland in 2006 by researchers. They then put it in a fridge-freezer, as is normal practice, unaware of its age. It was only when it was taken to a laboratory that scientists from Bangor University studied it and concluded it was 400 years old.
The discovery made it into the Guinness Book of World Records. However, by this time, it was too late for Ming the Mollusc(软体动物), named after the Chinese dynasty when its life began. Unfortunately researchers who calculated Ming’s age killed it instantly by opening its shell.
The researchers opened the ancient clam up to judge its age by counting growth rings inside. But the rings were so close together that scientists ended up having to count the rings on the outside to be accurate, leading CBS journalists to point out that if scientists had just started there, Ming could have lived on. Now, after examining the quahog more closely, using more advanced methods, the researchers have found the animal was actually 100 years older than they first thought.
Dr Paul Butler, from the University’s School of Ocean Sciences, said: “We got it wrong the first time and maybe we were a bit hasty publishing our findings back then. But we are absolutely certain that we’ve got the right age now.” The mollusc was born in 1499 – just seven years after Columbus discovered America and before Henry VIII had even married his first wife, Catherine of Aragon in 1509.
A quahog’s shell grows by a layer every year, in the summer when the water is warmer and food is plentiful. It means that when its shell is cut in half, scientists can count the lines in a similar way that trees can be dated by rings in their trunks.
Jan Heinemeier, associate professor at the University of Denmark, who helped date Ming, told Science Nordic: “The fact that we got our hands on a 507-year-old animal is incredibly fascinating, but the really exciting thing is of course everything we can learn from studying the mollusk.”At first, the scientists found that _____________.
| A．The ocean quahog got a deadly disease |
| B．The growth rings inside were so close together |
| C．it was accurate to count the growth rings outside |
| D．The ocean quahog was 400 years old |
Why did the scientists open the ancient clam up?
| A．To count the growth rings outside of the clam. |
| B．To study how old the clam was. |
| C．To see the structure of it. |
| D．To give an immediate operation on it. |
The sixth paragraph is mainly about_____________.
| A．How to calculate the age of a tree |
| B．Why a quahog’s shell grows by a layer each year |
| C．How to calculate the age of a quahog |
| D．Why a quahog likes it when the water is warmer |
Which of the following is NOT true?
| A．The researchers have got the right age of the ocean quahog. |
| B．The mollusc was born after Columbus discovered America. |
| C．The ocean quahog was named after the Chinese dynasty. |
| D．A quahog’s shell grows by a layer every season. |
Where does the text probably come from?
| A．A magazine of marine life. | B．A travel brochure. |
| C．A biography. | D．A science fiction. |
Hacking our senses to boost learning power
Some schools are pumping music, noises and pleasant smells into the classroom to see if it improves exam results. Could it work? Why do songs stick in our heads? What does your school smell like? Is it noisy or peaceful?
It might not seem important, but a growing body of research suggests that smells and sounds can have an impact on learning, performance and creativity. Indeed, some head teachers have recently taken to broadcasting noises and pumping smells into their schools to see whether it can boost grades. Is there anything in it? And if so, what are the implications for the way we work and study?
There is certainly some well-established research to suggest that some noises can have a harmful effect on learning. Numerous studies over the past 15 years have found that children attending schools under the flight paths of large airports fall behind in their exam results. Bridget Shield, a professor of acoustics (声学) at London South Bank University, and Julie Dockrell, from the Institute of Education, have been conducting studies on the effects of all sorts of noises, such as traffic and sirens (汽笛), as well as noise generated by the children themselves. When they recreated those particular sounds in an experimental setting while children completed various learning tasks, they found a significant negative effect on exam scores. “Everything points to a bad impact of the noise on children’s performance, in numeracy, in literacy, and in spelling,” says Shield. The noise seemed to have an especially harmful effect on children with special needs.
Whether background sounds are beneficial or not seems to depend on what kind of noise it is — and the volume. In a series of studies published last year, Ravi Mehta from the College of Business at Illinois and his colleagues tested people’s creativity while exposed to a soundtrack made up of background noises — such as coffee-shop chatter and construction-site drilling — at different volumes. They found that people were more creative when the background noises were played at a medium level than when volume was low. Loud background noise, however, damaged their creativity.
Many teachers all over the world already play music to students in class. Many are inspired by the belief that hearing music can boost IQ in later tasks, the so-called Mozart effect. While the evidence actually suggests it’s hard to say classical music boosts brainpower, researchers do think pleasant sounds before a task can sometimes lift your mood and help you perform well, says Perham, who has done his own studies on the phenomenon. The key appears to be that you enjoy what you’re hearing. “If you like the music or you like the sound — even listening to a Stephen King novel — then you do better. It doesn’t matter about the music,” he says.
So, it seems that schools that choose to prevent disturbing noises and create positive soundscapes could enhance the learning of their students, so long as they make careful choices. Yet this isn’t the only sense being used to affect learning. Special educational needs students at Sydenham high school in London are being encouraged to revise different subjects in the presence of different smells — grapefruit scents for maths, lavender for French and spearmint for history.The four questions in the first paragraph are meant to ________.
| A．create some sense of humour to please the readers |
| B．provide the most frequently asked questions in schools nowadays |
| C．hold the readers’ attention and arouse their curiosity to go on reading |
| D．declare the purpose of the article: to try to offer key to those questions |
What does the conclusion of the studies of noise conducted by Bridget Shield and Julie Dockrell suggest?
| A．Peaceful music plays an active role in students’ learning. |
| B．Not all noises have a negative impact on children’s performance. |
| C．We should create for school children a more peaceful environment. |
| D．Children with special needs might be exposed to some particular sounds. |

| B．we may play some Mozart music while students are learning |
| C．a proper volume of background noises does improve creativity |
| D．noise of coffee-shop chatter is better than that of construction-site drilling |

A Korean wave is sweeping across China, with many Chinese women worshipping South Korean actors Kim Soo Hyun and Lee Min Ho as demigods (半神半人). Chinese netizens have always been divided over South Korean TV dramas, but there is no doubt that programs from the neighboring country are now enjoying a new round of popularity in China. And a big part of the credit for that goes to You Who Came From The Star, the South Korean TV series which is on the air now.
Top South Korean actors Jun Ji-hyun and Kim Soo Hyun recently earned a popularity rating of 24.8 percent in their country, considered strong by Nielsen Korea. You Who Came From The Star and The Heirs have been subjects of hot online discussions throughout Asia. Besides, the book, The Miraculous Journey of Edward Tulane, read by the hero in You Who Came From The Star was a hard-to-get item on Amazon for a while.
The two TV programs have several common elements: a tall, handsome, and rich hero who loves the heroine blindly and always protects her, and an equally handsome man madly in love with the same woman. Both programs portray the purity of love, which is expressed through a kiss or a warm hug. Perhaps that’s the secret of their success; perhaps people are still fascinated by Cinderella-type stories.
The growing wealth gap is a matter of social concern both in South Korea and China, and the challenges that young people face in their search for a better life might have prompted (激起) many ordinary girls to dream of marrying rich, caring men. This is precisely what the popular South Korean TV dramas portray. In fact, South Korean TV dramas are tailored to meet the market’s demands.
In contrast, Chinese TV screens are flooded by knock-off (山寨) or poorly made soap operas. There are too many Chinese TV dramas that are either of the stereotyped (刻板的) war theme or just blindly copy foreign programs. The lack of good stories has resulted in loads of TV series on time travel or fights in the harems (后宫) of Qing Dynastyemperors. These, in short, are the pain of Chinese TV productions.
The shooting for South Korean productions generally starts when the scripts (脚本) are just one-third ready. Many popular productions have their own websites, where scriptwriters post part of the finished scripts, inviting viewers to leave messages, discuss the plot and come up with suggestions for future events. This not only keeps viewers’ interest in the TV dramas alive, but also helps scriptwriters and directors make changes to the storylines to suit the audience’s demand.
Hopefully, the innovation-induced (创新引导的) success of South Korean TV programs will prompt Chinese TV drama makers to think up new ideas and abandon their bad practice of copying foreign productions in order to attract more viewers at home, and possibly abroad.The main point the author emphasizes in this passage is ________.
| A．why Korean actors are more popular than Chinese actors |
| B．how the three Korean actors became famous around East Asia |
| C．what modern TV dramas need is not copying foreign programs but innovation |
| D．the Cinderella-type stories are an ever-lasting theme people are fascinated with |
Which of the following best explains people’s favor for The Miraculous Journey of Edward Tulane?
| A．The celebrity effect is powerful. |
| B．Drama stars are the best advertisements. |
| C．Rich and handsome heroes in dramas usually love reading. |
| D．A successful drama generally originates from a good novel. |
According to the passage, the secret to Korean TV dramas’ being successful is that ________.
| A．drama stars must be tall, rich and handsome or beautiful |
| B．scriptwriters should choose the appropriate themes for all viewers |
| C．drama producers have creative ideas to adapt to viewers’ interest and demand |
| D．people’s concerns such as wealth gap both in Korea and China are taken good care of |
What does the last paragraph imply?
| A．Abandoning copying foreign productions is the only way to attract viewers. |
| B．The Chinese TV drama makers should follow in the footsteps of the Koreans. |
| C．It’s hard to predict what the future TV dramas in China and Korea will be like. |
| D．A bright future of Chinese TV dramas can be expected prompted by the Koreans. |
