How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses （感觉） how long and how well you brush, and it lets you track（跟踪） 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 （无线的） 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 （设备）on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart and 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, from $99 to $199, and the U.S. is the first target market. ( 目标市场)All of the following statements are wrong except ____________.

I travel a lot, and I find out different "styles" of directions every time I ask "How can I get to the post office?"
Foreign tourists are often confused in Japan because most streets there don't have names; in Japan, people use landmarks in their directions instead of street names. For example, the Japanese will say to travelers, "Go straight down to the corner. Turn left at the big hotel and go past a fruit market. The post office is across from the bus stop."
In the countryside of the American Midwest, there are not usually many landmarks. There are no mountains, so the land is very flat; in many places there are no towns or buildings within miles. Instead of landmarks, people will tell you directions and distances. In Kansas or Iowa, for example, people will say, "Go north two miles. Turn east, and then go another mile."
People in Los Angeles, California, have no idea of distance on the map; they measure distance in time, not miles. "How far away is the post office?" you ask. "Oh," they answer, "it's about five minutes from here." You say, "Yes, but how many miles away is it?" They don't know.
It's true that a person doesn't know the answer to your question sometimes. What happens in such a situation? A New Yorker might say, "Sorry, I have no idea." But in Yucatan, Mexico, no one answers "I don't know." People in Yucatan believe that "I don't know" is impolite. They usually give an answer, often a wrong one. A tourist can get very, very lost in Yucatan!When a tourist asks the Japanese the way to a certain place they usually________.
| A．refer to recognizable buildings and places |
| B．show him a map of the place |

| B．It's important for travelers to understand cultural differences. |
| C．People have similar understandings of politeness. |

It seems that people are gradually losing their smartness as smartphones become increasingly important assistants in their lives. As we rely too much on technology instead of our brains, many people have lost three basic abilities.
The first skill many people have lost is remembering phone numbers. Because phone numbers are stored in smartphone contacts, there's now no need to dial a number or look at it again. This is fine until you need to call someone for help, only to find your phone is not around.
And some people may also have lost their sense of direction because navigation apps can guide people anywhere they want. People get so dependent on them that when they can't use their smartphones, they get lost and anxious.
But the worst lost skills may be social ones, meaning that some people are becoming socially inept(无能的)People often bury themselves in their smartphones. As we're too absent-minded by what's happening in the virtual(虚拟的)world, some of us have lost conversational skills and sometimes can't even distinguish whether a person is happy or not.
Last August, researchers at the University of California, Los Angeles, studied 51 students aged 11 and 12 who had over five hours' screen time every day. Their task was to tell the emotions of 48 pictures of faces that were happy, sad, angry or scared.
The children made an average of 14.02 mistakes at the beginning. But after a five-day camp without electronic products, they made only 9.41 mistakes on average.
Luckily, people still have a chance to get these abilities back. You should try to keep your parents' numbers in mind for emergencies. You should also pay more attention to street signs and stores , which will help you to draw a mind map and stop you from getting lost. And the easiest solution to social skill loss is to take a break from electronic products. The underlined sentence in the second paragraph implies that__________.
| A．you are unable to contact others without your smart phone |
| B．others are able to call you anytime and anywhere |
| C．others are unable to get in touch with you by smartphone |
| D．you are able to turn to others for help |
Overusing smartphones, people will probably_______ according to the passage.
| A．find their destination without difficulty |
| B．have no sense of numbers |
| C．weaken their senses of hearing and sight |
| D．lose face-to-face communication skills |
The passage mainly tells us that many people are__________.
| A．becoming no smarter than smartphones |
| B．benefiting from smartphones' intelligence |
| C．losing some basic abilities because of using samrtphones |
| D．trying hard to break away from smartphones’ intelligence |
The writer’s attitude towards electronic products is__________.
| A．supportive | B．sympathetic |
| C．critical | D．optimistic |
