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 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. ( ) All of the following statements are wrong except   _  . A) It can sense how users brush their teeth. B) It can track users' school performance. C) It can check users' fear of seeing a dentist. D) It can help users find their phones.

We know that many animals do not stay in one place.Birds,fish and other animals move from one place to another at a certain time.They move for different reasons:most of them move to find food more easily,but others move to get away from places that are too crowded. When cold weather comes,many birds move to warmer places to find food.Some fishes give birth in warm water and move to cold water to feed.The most famous migration is probably the migration of fish,which is called "Salmon".This fish is born in fresh water but it travels many miles to salt water.There it spends its life.When it is old,it returns to its birthplace in fresh water.Then it gives birth and dies there.In northern Europe,there is a kind of mouse.They leave their mountain homes when they become too crowded.They move down to the low land.Sometimes they move all the way to the seaside,and many of them are killed when they fall into the sea. Recently,scientists have studied the migration of a kind of lobster .Every year,when the season of bad weather arrives,the lobsters get into a long time and start to walk across the floor of the ocean.Nobody knows why they do this,and nobody knows where they go. So,sometimes we know why humans and animals move from one place to another,but at other times we don't.Maybe living things just like to travel. Most animals move from one place to another at a certain time to   _  . A) give birth B) enjoy warmer water C) find food more easily D) find beautiful places

I have a friend named John Roberts who owns a horse ranch  in San Ysidro.The last time I was there he shared a story with me. "It is a story about a young man who was the son of an itinerant horse trainer. When he was a senior,he was asked to write a paper about what he wanted to be and do when he grew up." That night he wrote a seven-page paper describing his goal of someday owning a horse ranch. He wrote about his dream in great detail and he even drew a diagram of a 200-acre ranch, showing the location of all the buildings,the stables and the track. "The next day he handed it in to his teacher. Two days later he received his paper back. On the front page was a large red F with a note that read, 'See me after class.'" "The boy went to see the teacher after class and asked, 'Why did I receive an F?'" "The teacher said, 'This is an unrealistic dream for a young boy like you. You have no money. You come from an itinerant family. You have no resources. Owning a horse ranch requires a lot of money. You have to buy the land. You have to pay for the original breeding stock and later you'll have to pay large stud fees. There's no way you could ever do it.' Then the teacher added, 'If you will rewrite this paper with a more realistic goal, I will reconsider your grade.'" "The boy went home and asked his father what he should do. His father said, 'Look, son, you have to make up your own mind on this. However, I think it is a very important decision for you.'" "Finally,after sitting with it for a week, the boy turned in the same paper, making no changes at all. He stated, 'You can keep the F and I'll keep my dream.'" John continued, "I tell you this story because you are sitting in the middle of my 200-acre horse ranch. I still have that school paper framed over the fireplace." He added, "If I had changed my paper at that time, maybe we would not have the chance to be here talking about the dreams ." What was the boy's goal described in his seven-page paper? A) to own a horse ranch B) to be a senior trainer C) to build many buildings D) to buy many horses.

Shirley Temple, who died on February 10, 2014, was that rare example of a Hollywood child star who, when the cameras stopped rolling, carved out a new career. For four years, she was Hollywood's biggest box-office star representing the kind of sweet, innocent girl that everyone wanted as their daughter. However, years later, she reappeared as a successful politician. Shirley Temple was born in Santa Monica, California on 23 April 1928. Encouraged by her mother, she learned to dance while she was just three. In 1934, Stand Up and Cheer became her first film and the film was a great success. At the age of six she was earning $1,250 a week -- more than $21,000 at today's values. Across the world, audiences flocked to see her in films such as Little Miss Marker, The Little Colonel and The Littlest Rebel. In 1935 she was awarded a special Oscar (Academy Award) and her foot and hand prints were added to those of stars such as Jean Harlow and Mary Pickford outside Grauman's Chinese theatre in Hollywood. The peak of her film career came in 1939 when The Little Princess became a box-office success. Temple starred in a total of 43 feature films. But she found it difficult to maintain her film career in adulthood and retired from Hollywood in 1950. She disappeared from the spotlight for nearly 20 years. She returned to the public eye in 1967, as a Republican candidate for Congress. When Nixon became president, he rewarded her with an appointment to the American delegation to the United Nations. Then, in 1974, President Ford appointed her the United States Ambassador  to Ghana. George Bush Snr, appointed her Ambassador to Czechoslovakia. Shirley Temple drew a line between her childhood stardom and her later political career. "Some people are stuck on this image of the little girl," she once said. "She is not me. We shouldn't live in the past; my life is now." Nevertheless, for many across the world, the name Shirley Temple always called to mind a superstar child. Shirley Temple died at the age of   _  . A) 75 B) 80 C) 86 D) 90
