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. |

Happiness is for everyone. You don' t need to care about those people who have beautiful houses with large gardens and swimming pools or those who have nice cars and a lot of money and so on. Why? Because those who have big houses may often feel lonely and those who have cars may want to walk on the country roads at their free time.
In fact, happiness is always around you if you put your heart into it. When you are in trouble at school, your friends will help you; when you study hard at your lessons, your parents are always taking good care of your life and your health; when you get success, your friends will say congratulations to you; when you do something wrong, people around you will help you to correct it. And when you do something good to others, you will feel happy, too. All these are your happiness. If you notice a bit of them, you can see that happiness is always around you.
Happiness is not the same as money. It is a feeling of your heart. When you are poor, you can also say you are very happy, because you have something else that can' t be bought with money. When you meet with difficulties, you can say loudly you are very happy, because you have more chances to challenge yourself. So you cannot always say you are poor and you have bad luck. As the saying goes, life is like a revolving(旋转的)door. When it closes, it also opens. If you take every chance you get, you can be a happy and lucky person.When you fall down in a PE class, both your teacher and your classmates will ______.

Debra Veal is a very brave woman. She took part in a race to row across the Atlantic，a journey for about 3, 360 kilometers.

Cultural Center Adds Classes for Young Adults
The Allendale Cultural Center has expanded its arts program to include classes for young adults. Director Leah Martin announced Monday that beginning in September, three new classes will be offered to the Allendale community. The course titles will be Yoga for Teenagers; Hip Hop Dance: Learning the Latest Moves; and Creative Journaling for Teens: Discovering the Writer Within. The latter course will not be held at the Allendale Cultural Center but instead will meet at the Allendale Public Library.
Staff member Tricia Cousins will teach the yoga and hip hop classes. Ms. Cousins is an accomplished choreographer (舞蹈教师) as well as an experienced dance educator. She has an MA in dance education from Teachers College, Columbia University, where she wrote a thesis on the pedagogical (教学法的) effectiveness of dance education. The journaling class will be taught by Betsy Milford. Ms. Milford is the head librarian at the Allendale Public Library as well as a columnist for the professional journal Library Focus.
The courses are part of the Allendale Cultural Center’s Project Teen, which was initiated by Leah Martin, Director of the Cultural Center. According to Martin, this project is a direct result of her efforts to make the center a more essential part of the Allendale community. Over the last several years, the number of people who have visited the cultural center for classes or events has steadily declined. Project Teen is primarily funded by a generous grant from The McGee Arts Foundation, an organization devoted to bringing arts programs to young adults. Martin oversees the Project Teen board, which consists of five board members. Two board members are students at Allendale’s Brookdale High School; the other three are adults with backgrounds in education and the arts.
The creative journaling class will be cosponsored by Brookdale High School, and students who complete the class will be given the opportunity to publish one of their journal entries in Pulse, Brookdale’s student literary magazine. Students who complete the hip hop class will be eligible to participate in the Allendale Review, an annual concert sponsored by the cultural center that features local actors, musicians, and dancers. All classes are scheduled to begin immediately following school dismissal, and transportation will be available from Brookdale High School to the Allendale Cultural Center and the Allendale Public Library. For more information about Project Teen, contact the cultural center’s programming office at 988-0099 or drop by the office after June 1 to pick up a fall course catalog.

The number of speakers of English in Shakespeare's time is estimated to have been about five million. Today it is estimated that some 260 million people speak it as a native language, mainly in the United States, Canada, Great Britain, Ireland, South Africa, Australia and New Zealand. In addition to the standard varieties of English found in these areas, there are a great many regional and social varieties of the language as well as various levels of usage that are employed both in its spoken and written forms.
In fact, it is impossible to estimate the number of people in the world who have acquired an adequate working knowledge of English in addition to their own languages. The purpose for English learning and the situations in which such learning takes place are so varied that it is difficult to explain and still more difficult to judge what forms an adequate working knowledge for each situation.
The main reason for the widespread demand for English is its presentday importance as a world language. Besides serving the indefinite needs of its native speakers, English is a language in which some of important works in science, technology, and other fields are being produced, and not always by native speakers. It is widely used for such purposes as meteorological and airport communications, international conferences, and the spread of information over the radio and television networks of many nations. It is a language of wider communication for a number of developing countries, especially former British colonies. Many of these countries have multilingual populations and need a language for internal communication in such matters as government, commerce, industry, law and education as well as for international communication and for entrance to the scientific and technological developments in the West. Which of the following statements is NOT true?
| A．Some 260 million people in the world have an adequate working knowledge of English. |
| B．There are some 260 million native speakers of English in the world. |
| C．It is almost impossible to estimate the number of people with an adequate working knowledge of English. |
| D．People learn English for a variety of reasons. |
According to the passage, what is the main reason for the widespread use of English?
| A．It was popular during Shakespeare's time. |
| B．It is used in former British colonies. |

| C．Being a multilingual. |
| D．Being a native speaker. |

Boys need friends, suffer when they don't believe they have any, and worry over the ups and downs of relationships. Many adults believe that somehow boys need friends less than girls do, in truth, though, no boy is an island; boys value their friends throughout childhood and adolescence and are happier and healthier when they have solid relationships with peers.
Despite the common belief that girls are better at relationships, most boys consider their friends a very important part of their lives, and boys may actually be better at keeping friendships than girls are. A recent study of 10 to 15yearold boys and girls found that girls' friendships are actually more fragile. Girls tend to say and do hurtful things to each other more frequently than boys, and girls are more hurt by the end of a friendship.
Boys are the living definition of the phrase “peer group”; they love games with rules, competition, and doing things together. Boys seem to enjoy, even need the opportunity to test themselves against others, and many lasting friendships begin in karate (空手道) class or on the basketball court. Competence and skill are widely respected; being picked last for a team or left out altogether is an experience that can haunt (萦绕心头) a boy for years.
As boys mature, the friendship becomes even more important, and it frequently widens to include girls. During the teen years, friends can become the most important part of a boy's life—and a part in which his parents are not included. The confusion of being a teenager leads boys to form close bonds with friends. There is the sense for many boys that a friend is someone who is “always there for me”， someone he can trust. They may be partners in crime or partners in study, but the friendship of adolescent boys can run surprisingly deep.According to the text, boys' friendship________.
| A．is usually built around active play |
