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.

29.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 detect users’ fear of seeing a dentist.

D.It can help users find their phones.

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

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

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

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

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

     People do not analyze every problem they meet. Sometimes they try to remember a solution from the last time they had a   21  problem. They often accept the opinion or ideas of other people. Other times they begin to act without thinking; they try to find a solution by trial and error.  22  ,when all of these methods fail, the person with a problem has to start analyzing. There are six   23  in analyzing a problem.

       24  the person must recognize that there is a problem. For example, Sam’s bicycle is broken,  and he cannot ride it to class as he usually does. Sam must   25  that there is a problem with his bicycle.

     Next the person must find the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must   26  the parts that are wrong.

     Now the person must look for   27  that will make the problem clearer and lead to   28  solutions. For example, suppose Sam decides that his bike does not work because there is something wrong with the brakes.  29  ,he can look in his bicycle repair book and read about brakes,  30  his friends at the bike shop, or look at his brakes carefully.

     After   31  the problem, the person should have   32  suggestions for a possible solution. Take Sam as an example   33  ,his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.

     In the end, one   34  seems to be the solution to the problem. Sometimes the   35  idea comes quite   36  because the thinker suddenly sees something new or sees something in a  37   way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He   38  hits on the solution to his problem: he must  39  the brake.

    Finally the solution is   40  .Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

   Hank Viscardi was 26 years old when he put on his first pair of long trousers and his first pair of shoes. For the first time he saw himself as he had always wanted to be a full five feet eight inches tall.
Hank had been born without legs. Until he was seven, his world was a world of repeated operations. At last he had not legs, but stumps（残肢）that could be fitted with a kind of special boots.
   Out of the hospital, Hank often found people staring at him with cruel interest. Children laughed at him and called him “Ape Man” because his arms dragged（拖）on the ground.
   He went to school like other boys. His grades were good and he needed only eight years instead of the usual twelve.
   After graduation, Hank worked his way through college. He swept floors, waited on table, or worked in one of the college offices. During all this busy life, Hank had been moving around on his stumps. But one day the doctor told him even the stumps were not going to last much longer. Hank would soon have to use a wheel chair.
   Hank felt himself go cold all over. However, the doctor said there was a chance that he could be fitted with artificial（人造的）legs.
Finally a leg maker was found and the day came when Hank stood up before the mirror and saw himself for the first time, five feet eight inches tall.
But this was not the end yet. He had to learn to use his new legs. Again and again he marched the length of the room, and marched back again. There were times when he fell down on the floor, but he pulled himself up and went back to the endless marching. He went out on the street. He climbed the stairs and learned to dance. He built a boat and learned to sail it.
When World War Ⅱ came, he talked the Red Cross into giving him a job. He took the regular training. He marched and drilled along with the other soldiers. Few knew that he was legless. This was the true story of Hank Viscardi, the man without legs.

       It was Sunday yesterday and my son and I walked a couple of miles in the morning. We got hungry so we decided to stop for a meal in a restaurant. While we were waiting in a line, a woman came in. She was very angry and talking about a beggar who had asked her for money. In her opinion, those people had the ability to earn their bread and butter.

I was feeling uncomfortable with the situation and wondering what I should say to my son later. I had told him that we should help those who were in need of help. At that time the lady said, "Today is my birthday, and nobody can bother me."

I knew this was my chance to help her change her thinking and to help her feel cared for on her birthday. I asked the waitress for help, telling her I wanted to pay for the woman's meal.

The waitress looked at me in surprise. I paid for our meal and that of the woman. When the woman finished eating her food, the waitress told her that it was I who had paid for her meal. Then the woman came to our table and tried to force her money on us. She even said, "I can't take your money, because I didn't help the person who asked me for money for food!"

I just smiled and said, "I just hope you have a very nice birthday."

She ended up sitting near us and talked with us. It turned out that she was crazy about animals. Hearing our stories of pet adoptions really cheered her up. "You are a nice father," she said.

She left, seeming to be happier and more thoughtful about all that had happened. I'd say it was worth the price.

When my friend Lesa was diagnosed(诊断) with cancer, another friend and I went to the hospital to spend some time with her. We bought her a small toy and  named him Lemon－Aide. We gave Lemon－Aide to Lesa and told her he was to go with her to all of her treatments to remind her that we were thinking of her and caring about her even though we could not always be with her. When the treatments were completed, she said when someone else needed him she would pass him along.

A few months later，much to my surprise, it was me that she passed him to. Lemon－Aide went with me to all of my treatments.

One day while waiting for my doctor I decided we could market the idea to fight cancer. Lesa thought it was a great idea so we founded the organization that came to be known as Lemon－Aide' s Friends, Inc. We designed our organization to remind people fighting cancer that there are people who love and care about them all the time. Today we have totally 5013 volunteers. The money raised is donated to cancer patients who do not have insurance. The Physicians on our Board of Advisors determine how and where our money is donated.

Lemon－Aide is for men, women, and children of all ages and to date has been sent to 34 states and 33 countries to provide smiling support for people fighting cancer. When life gave us lemons we made Lemon－Aide, a soft smiling toy that represents love, support, and encouragement.

Sit down, close your eyes and relax. Think about your childhood and the memories you created. What was your favorite childhood memory and what was your favorite as a child? Or what was your favorite Christmas present or your favorite candy bar when growing up? Answers may come easily for some people but for others, it may take more time to think about.

Mary Jo McCarthy of Pequot Lakes wants to help others document their childhood memories which could be treasured by current families and for generations to come. McCarthy, 64, a short story author and retired columnist(专栏作家) for the Lake Country Echo weekly newspaper, began hosting a writing seminar(研讨班)titled “A Time to Remember”. The classes are limited to 12 people and are conducted in the nursery at Lutheran Church of the Cross in Nisswa and the registration fee is $25.

McCarthy said what led her to start the writing seminars was writing others’ biographies. A retired businessman asked her to write his biography as a ghost writer. She said others from her church in Pequot Lakes had also asked her to write their biographies because they didn’t know how to write them. She thought hosting a class to help people write their own biographies would be more beneficial to them.

McCarthy said people had busy lifestyles those days and didn‘t have a chance to sit down and write down their memories that they might forget and never remember. She said writing down the memories would document the person’s life, go other family members, especially future generations would be able to read about them.

A university graduate described as a “respectable and intelligent” woman is seeking professional help after being convicted of （证明有……罪）shoplifting for the second time in six months.

    Ana Luz, recently studying for her PhD, has been told she could end up behind bars unless she can control the desire to steal from shops.

    Luz, who lives with her partner in Fitzwilliam Road,Cambridge, admitted stealing clothes worth ￡9.95 from John Lewis in Oxford Street ,London, on March 9.

    Phillip Lemoyne, prosecuting（起诉）, said Luz selected some clothes from a display and took them to the ladies’ toilet in the store. When she came out again she was wearing one of the skirts she had selected, having taken off the anti-theft security alarms（防盗警报装置）.

    She was stopped and caught after leaving the store without paying, Mr. Lemoyne said.

    He added that she was upset on her arrest and apologized for her actions.

    Luz, 28, was said to have been convicted of shoplifting by Cambridge judges last October, but Morag Duff, defending, said she had never been in trouble with the police before that.

She is otherwise a very respectable and intelligent young lady .She went to her doctor and asked for advice because she wants to know if there is anything in particular that caused her to do this.”

    Judge David Azan fined Luz ＄50, and warned:“You’ve got a criminal record. If you carry on like this, you will end up in prison, which will ruin your bright future you may have.”

    Luz achieved a degree in design at university in her native Spain, went on to a famous university in Berlin, Germany for her master’s degree and is now studying for a PhD at Cambridge University, UK.

Great inventions change the way we live ,The first great invention was one that is still very important today—the wheel. This made _ 61  easy for men to carry heavy things and to travel long distances. For  _62 （century）after that, there were few inventions that had as much effect as the wheel.

It is not easy to find true friends．Even if you’ve connected with someone，how do you really know he is a true friend？And often you will find that someone who you thought you could trust may have let you down．There are ways you can know if a friendship is true and how you can hold onto that friend．

Generally speaking，a true friend is someone who will be there for you no matter what happens．They will stand by you through bad and good times．They will accept you for who you are without trying to change you，and they will be there to help you grow in new ways．

A true friend will keep you secrets for you trust him．They will be honest and be someone you can depend on．They will listen and be someone you can talk things over with，even if they may not have advice to share with you．

However，friendship is a two-way street．To find true friends and keep them，you must in turn be the same as well．Be there for them in their hard times and share the good times with them．Be someone your friends can depend on as well and offer them the same thing they give to you．A friendship will fall apart fast if only one person is giving and putting all the effort．If you are the only one making an effort，be honest and it works．

Actually，there will be barriers in the road but that is the test of true friendship．If it can survive those barriers，it will be stronger and better than ever．Just as St Thomas Aquinas put it，“There is nothing on this earth more prized than friendship．”

Follow your doctor’s advice, ______ your illness will get better.

A. then     B. or       C. and      D. but

Increasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店). Some avoid doctors because of the high cost of medical care, especially if they lack health insurance. Or they may stay because they find it embarrassing to discuss their weight, alcohol consumption or couch potato habits. Patients may also fear what they might learn about their health, or they distrust physicians because of negative experiences in the past. But playing doctor can also be a deadly game.

Every day, more than six million Americans turn to the Internet for medical answers – most of them aren’t nearly skeptical enough of what they find. A 2012 survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. They shouldn’t. Look up “headache”, and the chances of finding reliable and complete information, free from a motivation for commercial gain, are only one in ten, reports an April 2015 Brown Medical School study. Of the 169 websites the researchers rated, only 16 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.

The problem is that most people don’t know the safe way to surf the Web. “They use a search engine like Google, get 18 trillion choices and start clicking. But that’s risky, because almost anybody can put up a site that looks authoritative(权威的), so it’d hard to know if what you’re reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.

12. According to the text, an increasing number of American _____.

A. are suffering from mental disorders

B. like to play deadly games with doctors

C. turn to Internet pharmacies for help

13. Some Americans stay away from doctors because they _____.

A. are afraid to face the truth of their health

D. are afraid to misuse their health insurance

14. According to the study of Brown Medical School, ______.

A. more than 6 million Americans distrust doctors

B. about 1/10 of the websites surveyed are of high quality

C. only 1/10 of medical websites aim to make a profit

D. 72% of health websites offer incomplete and faulty facts

15. Which of the following is the author’s main argument?

A. It’s cheap to self-treat your own illness.

B. It’s dangerous to be your own doctor.

C. It’s reasonable to put up a medical website.

D. It’s embarrassing to discuss your bad habits.

Different cultures

The cultures of the East and the West really distinguish each other a lot.36.______

The origin of the Eastern cultures is mainly from two countries: China and India. Both of the two cultures are developed by rivers—the Yellow River in China and the Indus River in India. 37.________

When the two mother rivers gave birth to the Eastern culture, another famous culture was brought up on the Mesopotamian Plain—the Mesopotamian Civilization. This civilization later on developed into the cultures of Ancient Greece and Ancient Rome.38.________ Like the Chinese culture, the European culture also crossed waters. When the British settled down in America, their culture went with them over the Atlantic Ocean. So the American culture doesn't distinguish from the European culture a lot.

39．________ Take the language system for example. In the East, most languages belong to the pictographic language while the Western languages are mostly based on the Latin system. Other causes like human race difference counts as well. But what's more, due to the far distance and the steep, areas between the East and West, the two cultures seldom communicate until recent centuries. So they grew up totally in their own ways with almost no interference(干扰)  from the other.

These differences are everywhere. 40.________ But different cultures make the world of 21st century more colourful. The cultural gap should not be the obstacle (障碍)  to the civilization of human being. It ought to be the motivation of our going farther.

A．Let us work together to keep a variety of culture.

B．One important thing is to learn about other cultures.

C．And these two are well known as the base of the European culture.

D．At the same time, some other differences add to the cultural differences.

E．This is because the culture systems are two separate systems on the whole.

F．They helped the two cultures develop for centuries and form their own styles.

G．They are obvious and affect people's ways of thinking and their views of the world.
