【题目】 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 (dont forget the insides of the teeth!) and make sure youre brushing long enough. Its 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, itll 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.

【题目】In the mid-1950s, I was a somewhat bored early-adolescent male student who believed that doing any more than necessary was wasted effort. One day, this approach threw me into embarrassment

In Mrs. Totten’s eighth-grade math class at Central Avenue School in Anderson, Indiana, we were learning to add and subtract decimals (小数).

Our teacher typically assigned daily homework, which would be recited in class the following day. On most days, our grades were based on our oral answer to homework questions.

Mrs. Totten usually walked up and down the rows of desks requesting answers from student after student in the order the questions had apeared on our homework sheets. She would start either at the front or the back of the classroom and work toward the other end.

Since I was seated near the middle of about 35 students, it was easy to figure out which questions I might have to answer. This particular time, I had completed my usual two or three problems according to my calculations.

What I failed to expect was that several students were absent, which threw off my estimate. As Mrs. Totten made her way from the beginning of the class,I desperately tried to determine which math problem I would get. I tried to work it out before she got to me, but I had brain freeze and couldn’t function.

When Mrs. Totten reached my desk,she asked what answer I’d got for problem No. 14. “I…I didn’t get anything, I answered,and my face felt warm.

“Correct,” she said.

It turned out that the correct answer was zero.

What did I learn that day? First, always do all your homework. Second, in real life it isn’t always what you say but how you say it that matters. Third,I would never make it as a mathematician.

If I could choose one school day that taught me the most, it would be that one.
