Question

【题目】 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 smart phone. It’s called the Kolibree toothbrush. It has different models, and will cost from $99 to $200.

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

3) whether you brush up and down instead of just side to side.

Then it will send the information to a mobile phone via Bluetooth, telling you whether you have brushed in a proper way. The Kolibree app records your progress and scores your brushing way to help you improve brushing habits.

The toothbrush will also be able to talk to other apps on your phone, so developers could create a game controlled by your toothbrush. That would be very interesting.

The Kolibree toothbrush was invented by Thomas Serval. He says the idea of inventing it came from his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They always answered “yes”, but Thomas used to find their toothbrush heads dry. He decided that a kind of brush was needed to tell him how well they brushed their teeth.

Thomas says that one day, it’ll be possible to use a brushing unit with a camera. The camera can even examine holes in your teeth while you brush.

Answer 1

【答案】

【1】name

【2】long

【3】correctly/properly

【4】inventing

【5】whether/if

【解析】

文章讲述了智能电动牙刷的一些事情。

【1】根据It's called the Kolibree toothbrush.可知它的名字是Kolibree toothbrush；故填name。

【2】根据the Kolibree will record 1)the time you spent brushing teeth,可知它能记录你刷了多长时间的牙；故填long。

【3】根据 whether you brush up and down instead of just side to side.正确的刷牙方式是上下刷而不是左右刷；这里需要副词，修饰动词brush；故填 correctly/properly。

【4】根据 He says the idea of inventing it came from his experience as a father.和后面表格可知是发明它的原因，因for介词，后面用doing；故填inventing。

【5】根据空格前的Thomas decided to design it after doubting中的doubt可知，这里应该是提出一个问题，宾语从句中对于一般疑问句的引导用if/ whether，所以这里填if/ whether。
