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 doctor 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(应用) on your phone, so developers could, for example, create a game controlled by your toothbrush. You could score points for beating monsters(怪物) 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.

1.Which is one of the features of the Kolibree toothbrush?

A. It can sense how users brush their teeth.

B. It can track users’ school performance.

C. It can cause users’ fear of seeing a doctor.

D. It can help users find their phones.

2.What can we learn from Serval’s words in Paragraph 3?

A. You will find it enjoyable to see a doctor.

B. You should see your doctor on a day-to-day basis.

C. You can brush with the Kolibree as if guided by a doctor.

D. You’d like a doctor to watch you brush your teeth every day.

3.What is Paragraph 5 mainly about?

A. How Serval found out his kids lied to him.

B. Why Serval thought brushing teeth was necessary.

C. How Serval taught his kids to brush their teeth.

D. What inspired Serval to invent the toothbrush.

4.What can we learn about the future development of the Kolibree?

A. The brush handle will be removed.

B. A mobile phone will be built into it.

C. It will be used to fill holes in teeth.

D. It will be able to check users’ teeth.

What do you do if you are hit in the mouth and one of your teeth is knocked out? A dentist(牙医)may be able to put the tooth back in for you, but you have to get to the dentist first．In the meantime, you have to store the tooth so that it will stay healthy．

The simplest thing to do is put the tooth back into your mouth, or you could put it in milk．Frank Courts, a dentist at the University of Florida, worked with other researchers to find the safest way of keeping knocked-out teeth．He tried putting teeth into milk, into water, and into cell-culture medium(细胞培养液)．He also tried, just drying the teeth in the open air．He used teeth that had to be removed from people’s mouths for various reasons．The teeth were put into one of the solutions(溶液)or stored in the air for one hour．Then cells from the root of the teeth were scraped-off the teeth．Dr．Courts and the others then studied how healthy these cells were．

The cell-culture medium worked best to keep a knocked-out tooth healthy outside the mouth．However, few people keep cell-culture medium handy at home or in school．

The next best thing was milk．But Dr．Courts said that the best thing of all was to wash the tooth and put it right back into its socket(牙槽)in the mouth．For some people, though, this is just too painful or upsetting．So milk will do, until you get your tooth (and your mouth)to a dentist．

1.This passage is mainly about              ．

A. how a dentist can save a knocked-out tooth

B. how to keep a knocked-out tooth healthy

C．how Dr．Courts and other researchers made their experiments

D．how to put a knocked-out tooth back into its socket

2.The best way to keep a knocked-out tooth healthy outside the mouth is to store it       .

A．in cell-culture medium    B．in milk     C．in water    D．in the open air

3.Milk can be used instead of cell-culture medium to put a knocked-out tooth in because     ．

A．milk works better to keep the tooth healthy  B．milk causes less pain

C．cell-culture medium is not usually handy    D．cell-culture medium is more expensive

4.“Dr．Courts said that the best of al1 was to wash the tooth and put it right back into its socket in the mouth．”In the sentence, the word “best” means              .

A．cheapest and healthiest                  B．least painful and cheapest

C．quickest and least painful                D．easiest and healthiest

Pick the right toothbrush

Most dentists say that a soft-upraised toothbrush with a small head is best for removing dirt and rubbish while getting into those hard-to-reach places. 2. They have limited skills in their hands and thus they can do a better job at cleaning teeth.

There are many things you can do to keep friendship strong forever.

Trust is very important in keeping any relationship strong and long lasting. If you trust the person whom you have a good relationship with and the other person also trust you in the same way, then you two have a good relationship.

You can remember important date of your friends such as their birthdays and wish them or give gifts to them on the special days. Many people say that money is the most important thing to consider, but remember friendship is not about money. You can find something small and inexpensive for their gifts or send online cards.

A friend should also always help others even when it is not very convenient. So have a helping hand ready at all times.

Sometimes distance makes relationships even closer. So, if you are far from your friends, there are many ways you can remain in contact（联系）. You can use email, chat programs, and you can also write a blog and share your daily life activities with your friends.

If there is anything that makes you happy, share it with your friends. Listen to their thoughts as well. If they have achieved something noticeable, congratulate them and celebrate with them.

I have seen good friendships and when there is unhealthy competition between two friends. Though this may not happen in many cases, it is better to keep this idea in mind since it may happen to you.

As far as I have seen and experienced, it will be better not to either lend to or borrow money from your good friend. Of course, we have to do this with friends. But, attention should be paid so that your friendship may not end.
