D 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, 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, 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. 56. Which is one of the feature 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. 57. 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. 58. Which of the following might make the Kolibree toothbrush fun? A. It can be used to update mobile phones. B. It can be used to play mobile phone games C. It can send messages to other users D. It can talk to its developers. 59. 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 60. What can we infer about Serval’s children? A. They were unwilling to brush their teeth B. They often failed to clean their toothbrushes. C. They preferred to use a toothbrush with a dry head. D. They liked brushing their teeth after Serval came home. 61. What can we learn about the future development of the Kolibree? A. The brush handle will be removed. B.

Sometimes you’ll hear people say that you can’t love others until you love yourself. Sometimes you’ll hear people say that you can’t expect someone else to love you until you love yourself. Either way, you’ve got to love yourself first and this can be tricky. Sure we all know that we’re the apple of our parents’ eyes, and that our Grandmas think we’re great talents and our Uncle Roberts think that we will go to the Olympics, but sometimes it’s a lot harder to think such nice thoughts about ourselves. If you find that believing in yourself is a challenge, it is time you built a positive self-image and learnt to love yourself.

Self-image is your own mind’s picture of yourself. This image includes the way you look, the way you act, the way you talk and the way you think. Interestingly, our self-images are often quite different from the images others hold about us. Unfortunately, most of these images are more negative than they should be. Thus changing the way you think about yourself is the key to changing your self-image and your whole world.

The best way to defeat a passive self-image is to step back and decide to stress your successes. That is, make a list if you need to, but write down all of the great things you do every day. Don’t allow doubts to occur in it.

It very well might be that you are experiencing a negative self-image because you can’t move past one flaw or weakness that you see about yourself. Well, roll up your sleeves and make a change of it as your primary task. If you think you’re silly because you aren’t good at math, find a tutor. If you think you’re weak because you can’t run a mile, get to the track and practice. If you think you’re dull because you don’t wear the latest trends, buy a few new clothes. But remember, just because you think it doesn’t mean it’s true.

The best way to get rid of a negative self-image is to realize that your image is far from objective, and to actively convince yourself of your positive qualities. Changing the way you think and working on those you need to improve will go a long way towards promoting a positive self-image. When you can pat yourself on the back, you’ll know you’re well on your way. Good luck!

According to the passage, our self-images _________.

A. have positive effects                 B. are probably untrue

C. are often changeable                 D. have different functions

You need to build a positive self-image when you _________.

A. dare to challenge yourself             B. feel it hard to change yourself

C. are unconfident about yourself         D. have a high opinion of yourself

How should you change your self-image according to the passage?

A. To keep a different image of others.     B. To make your life successful.

C. To understand your own world.         D. To change the way you think.

What is the passage mainly about?

A. How to prepare for your success.       B. How to face challenges in your life.

C. How to build a positive self-image.      D. How to develop your good qualities.

Who are the intended readers of the passage?

A. Parents.      B. Adolescents.        C. Educators.     D. People in general.

Have you ever noticed what happens to an idea once you express it? Just talking about it or writing it down causes you to make it clear in your own mind. How can you use this to increase your brain power? Start writing.

By putting thoughts into words, you are telling yourself the logic (逻辑) behind what you think, feel, or only partly understand. Often, explaining a thought is the process of understanding. In other words, you increase your brain power by exercising your “explain power.”

Try this experiment. Explain how you’ll increase your brain power, even if you have no idea right now. Just start with anything, and create an explanation. For example, start with “I’ll learn chess,” or “I’ll read an article on the mind every week.” Explain how that will help. You’ll be surprised how often this becomes a workable plan, and if you actually do this, you’ll have a better understanding of your brain from now.

Another benefit of writing is that it helps you remember. Many, if not most, highly productive people are always taking notes. You can try keeping it all in your head, but if you keep a journal of your ideas the next time you’re working on a big project, you’ll probably have more success.

Want to understand a topic? Write a book about it. That’s an extreme example, but if you are learning something new, write a letter to a friend about it, and you will understand it better. Want to invent something? Write an explanation of the problem, why you want to solve it, and why it is worth solving, and you’re half-way there.

Writers don’t always write because they clearly understand something beforehand. Often, they write about something because they want to understand it. You can do the same. Writing will help bring you to an understanding. Give it a try.

What would be the best title for the text?

A. A Way on How to Write.

B. Increase Your Brain Power through Writing.

C. Brain Power Helps Improve Your Writing.

D. How to Start Your Writing.

According to the text, writing can help you a lot in the following ways EXCEPT ______.
