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,” Serval 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,depending 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 features 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. |
| D．It can help users find their phones. |
What can we learn from Serval’s words in Paragraph 3?
| A．You will find it enjoyable to see a dentist. |
| B．You should see your dentist on a day-to-day basis. |
| C．You can brush with the Kolibree as if guided by a dentist. |

There is no better way to enjoy Scottish traditions than going fishing and tasting a little bit of whisky(威士忌)at a quiet place like the Inverlochy Castle. When Queen Victoria visited the castle in 1873, she wrote in her diary, “I never saw a lovelier spot ,” And she didn’t even go fishing.
Scotland is not easily defined. In certain moments, this quiet land of lakes and grasses and mountains changes before your very eyes. When evening gently sweeps the hillside into orange light, the rivers, teeming with fish, can turn into streams of gold . As you settle down with just a fishing pole and a basket on the bank of River Orchy, near the Inverlochy Castle , any frustration(烦恼) will float away as gently as the circling water. It’s just you and purple, pink, white flowers, seeking a perfect harmony. If you are a new comer to fishing, learning the basics from a fishing guide may leave you with a lifetime’s fun. For many, fishing is more than a sport; it is an art.
Scotland offers interesting place where you can rest after a long day’s fishing. Set against a wild mountain and hidden behind woodland, the beautiful Inverlochy Castle Hotel below the Nevis is a perfect place to see the beauty of Scotland’s mountains. Ben Nevis is the highest of all British mountains, and reaching its 1343-metre top is a challenge. But it’s not just what goes up matters; what comes down is unique. More than 900 metres high, on the mountain’s north face, lies an all-important source of pure water. Its name comes from the Gaelic language “usquebaugh” or “water of life”; and it is the single most important ingredient(原料) in Scotland’s best known drink: whisky.The story of Queen Victoria is to show that _____.
| A．the queen is rich in tour experience |
| B．the Castle is a good place to go in Scotland |
| C．tasting whisky is better than going fishing |

Top lists are lecturing people on everything from “100 places to visit” to “100 books to read ”.
Aren't you just tired of being told what to do with your time?
Now you have a list to end all lists!
Take a look at the following two examples from the list of “101 things not to do”:
Swim with Dolphins（海豚）？
Swimming with dolphins is one of the world’s most profitable tourist activities. However, every dolphin will welcome having their busy, tiring day interrupted by tourists screaming and pushing around them in the water. Worse yet, when dolphins get too near to the boats loaded with tourists, they could get caught up in ropes and killed by propellers(螺旋桨).
Here’s a little secret. Dolphins look like smiling at you, but actually they’re just opening their mouths.
Go to See the Mona Lisa?
There must be something about the mysterious(神秘的)smile. The 6 million people who visit the lady in the Louvre every year can’t all be wrong, after all. But they can be quite annoying, standing in front of you, holding up their cameras to prevent you from seeing anything. In fact, it is hard for you to see the painting clearly because you have to stay away from it for security reasons. After queuing for hours, many tourists can remain in front of the painting only for 15 seconds at most.
If the mysterious lady in the picture knew her fate, she wouldn’t just be smiling, she’d be laughing.

One of my wonderful memories is about a Christmas gift . Unlike other gifts, it came without wrap(包装).
On September 11th ，1958，Mum gave birth to Richard. After she brought him home from hospital, she put him in my lap, saying, “I promised you a gift , and here it is.” What an honor！I turned four a month earlier and none of my friends had such a baby doll of their own. I played with it day and night. I sang to it. I told it stories .I told it over and over how much I loved it!
One morning, however, I found its bed empty. My doll was gone! I cried for it. Mum wept and told me that the poor little thing bad been sent to a hospital. It had a fever. For several days I Heard Mum and Dad whispering such words as “hopeless”, “pitiful”, and “dying”, which sounded ominous.
Christmas was coming. “Don’t expect any presents this year,” Dad said, pointing at the socks I hung in the living room. “If your baby brother lives, that’ll be Christmas enough.” As he spoke, his eyes filled with tears. I’d never seen him cry before .
The phone rang early on Christmas morning. Dad jumped out of bed to answer it. From my bedroom I heard him say, “What? He’s all right?” He hung up and shouted upstairs. “The hospital said we can bring Richard home !”
“Thank God !” I heard Mum cry .
From the upstairs window, I watched my parents rush out to the car. I had never seen them so happy. And I was also full of joy. What a wonderful day! My baby doll would be home. I ran downstairs.

Spring is coming, and it is time for those about to graduate to look for jobs. Competition is tough, so job seekers must carefully consider their personal choices. Whatever we are wearing，our family and friends may accept us, but the workplace may not.
A high school newspaper editor said it is unfair for companies to discourage visible tattoos (纹身）nose rings, or certain dress styles. It is true you can't judge a book by its cover, yet people do "cover" themselves in order to convey (传递)certain messages. What we wear, including tattoos and nose rings, is an expression of who we are. Just as people convey messages about themselves with their appearances， so do companies. Dress standards exist in the business world for a number of reasons, but the main concern is often about what customers accept.
Others may say how to dress is a matter of personal freedom, but for businesses it is more about whether to make or lose money. Most employers do care about the personal appearances of their employees (雇员),because those people represent the companies to their customers.
As a hiring manager I am paid to choose the people who would make the best impression on our customers. There are plenty of well-qualified candidates, so it is not wrong to reject someone who might disappoint my customers. Even though I am open-minded, I can't expect all our customers are.
There is nobody to blame but yourself if your set of choices does not match that of your preferred employer. No company should have to change to satisfy a candidate simply because he or she is unwilling to respect its standards, as long as its standards are legal.

Eating too much fatty food, exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately: the air you breathe.
Previous studies have linked high exposure (暴露）to environmental pollution to an increased risk of heart problem, but two analyses now show that poor air quality can lead to heart attack or stroke (中风）within as little as a few hours after exposure. In one review of the research, scientists found that people exposed to high levels of pollutants (污染物）were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. A separate study of stroke patients showed that even air that the U. S. Environmental Protection Agency (EPA) considers to be of “moderate” (良好）quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.
The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.The text mainly discusses the relationship between.
| A．heart problems and air quality |
| B．heart problems and exercising |
| C．heart problems and smoking |
| D．heart problems and fatty food |
The underlined word “modest” in Paragraph 3 most probably means.
| A．relatively high | B．extremely low |
| C．relatively low | D．extremely high |
What can we learn from the text?
| A．Eating fatty food has immediate effects on your heart. |
| B．The EPA conducted many studies on air quality. |
| C．Moderate air quality is more harmful than smoking, |
| D．Stricter regulations on pollutants should be made. |
The author’s purpose of writing the text is most likely to.
| A．inform | B．persuade | C．describe | D．entertain |
