点评 反意疑问句是由陈述句和附加问句构成.通常附加问句要和前面的陈述句保持一致,但如果是复合句,要分两种情况:正常情况附加问句要和主句保持一致;如果主句的主语是第一人称,谓语动词是表示看法和主张的,附加问句要和从句保持一致.反意疑问句的回答也要注意两种情况:陈述句是肯定,附加问句是否定时,回答和一般疑问句一样;陈述句是否定,附加问句是肯定时,回答要根据事实来回答.切记:yes翻译为不,no翻译为对.本题考查特殊的祈使句的反问.

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.
