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(跟踪) 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 through a Bluetooth wireless(无线的) 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(发明家).

The toothbrush will also be able to talk to other applications(设备) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. "We try to make it smart and fun," Serval says.

Serval says he got the idea 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, from $99 to $199, and the U.S. is the first target market.

1.All the following statements are wrong EXCEPT_________.

A. It can sense how users brush their teeth.　　 B. It can track users' school performance.

C. It can check users' fear of seeing a dentist.　　 D. It can help users find their phones.

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.What can we infer(推断)about Serval's children?

A. They were unwilling to brush their teeth.

B. They often failed to clean their toothbrushes.

How fit are your teeth? Are you lazy about brushing them? We brush our teeth every day but few people know how well we're brushing. Today, a French company has introduced an electric toothbrush, which can work wirelessly（无线地）with a smartphone. It's called the Kolibree toothbrush. It has different models, and will cost from$99 to$200 .The US is the first target market.
Users download an app and connect via Bluetooth, and the Kolibree will record: 1 .the time you spent brushing teeth. 2.whether all areas of your mouth are reached.

The Kolibree records your progress and scores your brushing way to help you improve brushing habits. It's kind of like having a private dentist actually watch your brushing on a day-to-day basis.
