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.

【长难句解析】
1.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.
【翻译】这种牙刷还可以和其他的手机应用进行交流，那么开发者就可以创造一种由你的牙刷控制的游戏。
【分析】本句中的so表示上下文之间的因果关系，是一个并列连词。句中的for instance是一个插入语，过去分词短语controlled by your toothbrush在句中充当定语修饰前面的名词a game，这主要是因为动词control与game之间构成被动关系。
2. He would come home from work and ask his kids if they had brushed their teeth.
【翻译】他下班回家以后经常会问他的孩子是否已经刷牙了。
【分析】本句中的情态动词would表示过去常常做某事，would表示过去常常做，现在可能还在做；而used to do sth表示过去常常做，现在不做了。另外句中的宾语从句if they had brushed their teeth中的if表示“是否”，而不是“如果”。
