Question

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.

【解析】

试题分析：本文介绍了一款新型的牙刷Kolibree的功能以及发明者Serval发明这样产品的原因和目的。

1.A 推理题。根据第一段第2句An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone.可知这种电子牙刷能够感知到你刷牙多长时间，刷的多么好。故A正确。B项错在school performance，这款牙刷并不能记录用户在学校的表现。

2.C 推理题。根据第三段第2句“It’s kind of like having a dentist actually watch your brushing on a day-to-day basis,” says Thomas Serval, the French inventor.可知这款牙刷就像是有一名牙医在注意着你是如何刷牙的。故C项说法正确。

3.B 推理题。根据文章第四段第2句You could score points for beating monsters among your teeth.“We try to make it smart but also fun,” Serval says.可知这款牙刷还能用来玩游戏。这就更增加了它的趣味性。故B正确。

主旨大意题主要是测试考生对一篇文章或一段文字的深层理解程度及在速读中准确把握文章主旨大意的能力。一般针对某一语段或某一语篇的主题标题或目的设题。目的主旨大意题的设题方法：

The author’s main purpose in writing the passage is ______.

The passage is meant to _____ The purpose of this article is _______

文章或段落的主题句常常会出现在一些标志性的提示后。如：on the whole, as a result, in short, therefore, thus…..I agree with the opinion that….Given all these points above, I would support the idea that….; For all the reasons mentioned above, I would prefer….

文章中每一段落的中心距通常都是文章第一句或者最好一句。以本文32题为例：What is Paragraph 5 mainly about?文章第五段主要讲述什么？抓住本段第一句Serval says he was inspired by his experience as a father.可知他发明这样的牙刷是因为他的孩子的行为。
