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.

A. It can sense how users brush their teeth.

B. It can track users’ school performance.

D. It can help users find their phones.

2.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.

D. You’d like a dentist to watch you brush your teeth every day.

3.Which of the following might make the Kolibree toothbrush fun?

A. It can be used to update mobile phones.

B. It can be used to play mobile phone games.

C. It can send messages to other users.

From the health point of view we are living in a marvelous age. We are immunized (免疫) from birth against many of the most dangerous diseases. A large number of once deadly illnesses can now be cured by modern drugs and medical treatment. It is almost certain that one day cures will be found for the most stubborn remaining diseases. The expectation of life has increased enormously. But though the possibility of living a long and happy life is greater than ever before, every day we witness the unbelievable slaughter (屠杀) of men, women and children on the roads. Man vs the motor-car! It is a never-ending battle which man is losing. Thousands of people the world over are killed or horribly killed each year and we are quietly sitting back and letting it happen.

It has been rightly said that when a man is sitting behind a steering wheel (方向盘), his car becomes the extension of his personality. There is no doubt that the motor-car often brings out a man’s very worst qualities. People who are normally quiet and pleasant may become unrecognizable when they are behind a steering-wheel. They are ill-mannered and aggressive, willful as two-year-olds and absolutely selfish. All their hidden disappointments and regrets seem to be brought by the act of driving.

The surprising thing is that society smiles so kindly on the motorist and seems to forgive his behavior. Everything is done for his convenience. Cities are allowed to become almost impossible to live in because of heavy traffic; towns are made ugly by huge car parks; the countryside is ruined by road networks; and the mass annual slaughter becomes nothing more than a statistic, to be conveniently forgotten.

It is high time a world system of laws were created to reduce this senseless waste of human life. As for driving, the laws of some countries are not strict and even the strictest are not strict enough. Here are a few examples of some the things that might be done. The driving test should be standardized and made far more difficult than it is; all the drivers should be made to take a test every three years or so; the age at which young people are allowed to drive any vehicle should be raised to at least 21; all vehicles should be put through strict annual tests for safety. Even the smallest amount of alcohol in the blood can affect a person’s driving ability. Present drinking and driving laws (where they exist) should be made much stricter. Maximum and minimum speed limits should be introduced on all roads. Governments should lay down safety specifications (规范) for manufacturers, as has been done in the USA. All advertising stressing power and performance should be banned. These measures may sound inordinately severe. But surely nothing should be considered as too severe if it results in reducing the annual toll of human life. After all, the world is for human beings, not motor-cars.

1.The main idea of this passage is_________.

A. Traffic accidents are mainly caused by motorists.

B. Thousands of people the world over are killed each year.

C. The laws of some countries about driving are not too strict.

D. Only stricter traffic laws can prevent accidents.

2.What does the author think of society toward motorists?

A. Society laughs at the motorists.

B. Huge car parks are built in the cities and towns.

A. Driving can show his real self.

B. Driving can show the other part of his personality.

C. Driving can bring out his character.

D. His car can express his temper.

4. The attitude of the author is_________.

A. ironical B. critical

C. appealing D. favorable

When I was growing up, I was ashamed to be seen with my father. He was severely disabled and very short, and when we would walk together, his hand on my arm for balance, people would stare. If he ever noticed or was bothered, he never let it on.

It was difficult to coordinate(协调)our steps---his slow, mine impatient---and because of that, we didn’t say much as we went along. But as we started out, he always said, “You set the pace, I will try to adjust to you.”

He never talked about himself as an object of pity, nor did he show any envy of the more fortunate or able. What he looked for in others was a “good heart”, and if he found one, the owner was good enough for him.

Now that I am older, I believe that is a proper standard by which to judge people, even though I still don’t know accurately what a “good heart” is. But I know the times I don’t have one myself.

Unable to engage in many activities, my father still tried to participate(参加) in some way. I now know he participated in some things indirectly through me, his only son. When I played ball(poorly),he “played” too. When I joined the navy ,he “joined” too. And when I came home on leave ,he saw to it that I visited his office. Introducing me, he was really saying, “This is my son, but it is also me, and I could have done this, too, if things had been different.”Those words were never said aloud.

He has been gone many years now, but I think of him often. I wonder if he sensed my unwillingness to be seen with him during our walks. If he did, I am sorry I never told him how sorry I was, how unworthy I was, how I regretted it. I think of him when I complain about small affairs, when I am envious of another’s good fortune, when I don’t have a “good heart”.

At such times I put my hand on his arm to regain my balance, and say, “You set the pace, I will try to adjust to you.”

Dolphins are not fish, but warm-blooded animals. They live in groups, and speak to each other in their own language. In this way they are like other animals, such as bees and birds. But dolphins are very different from almost all land animals. Their brains are nearly the same size as our own, and they live a long time—at least twenty or thirty years.

Like some animals, dolphins use sounds to help them find their way around. They also make these sounds to talk to each other and to help them find food. We now know they do not use their ears to receive these sounds, but the lower part of the mouth, called the jaw.

Strangely, dolphins seem to like man, and for thousands of years there have been stories about the dolphin and its friendship with people. There is a story about sailors in the 19th century. In a dangerous part of the sea off the coast of New Zealand, they learnt to look for a dolphin called Jack. From 1871 to 1903, Jack met every boat in the area and showed it the way. Then in 1903 a passenger on a boat called The Penguin shot and wounded Jack. He recovered and for nine years more continued to guide all ships through the area—except for The Penguin.

Today, some people continue to kill dolphins, but many countries of the world now protect them and in these places it is against the law to kill them.

Parents like their children to look good, but remember that sensory issues can cause a child discomfort, which can lead to breakdown. 2. Soft cottons and cottons are comfortable. Avoid nylon and netting. Not all children with special needs have a problem with these, but if yours does, sacrifice fashion for peace of mind for you both.
