Some of the most successful people in the world are the ones who've had the most failures. J.K. Rowling's first Harry Potter book was refused 12 times before it finally came out. Michael Jordan was cut from his high school basketball team. He lost hundreds of games and missed thousands of shots during his career. But he once said, "I have failed over and over and over again in my life. And that's why I succeed."

These people succeeded because they understood that you have to let your failures teach you. You have to let them show you what to do differently the next time. So if you get into trouble, that doesn't mean you're a troublemaker, it means you need to try harder to act right. If you get a bad grade, that doesn't mean you're stupid, it just means you need to spend more time studying. No one's born being good at all things, You become good at things through hard work. You don't hit every note the first time you sing a song. You've got to practice.

Don't be afraid to ask questions. Don't be afraid to ask for help when you need it. I do that every day. Asking for help isn't a sign of weakness, it's a sign of strength because it shows you have the courage to admit when you don't know something, and that then allows you to learn something new. So find an adult that you trust - a parent, a grandparent or a teacher - and ask them to help you stay on track to meet your goals.

Now, your families, your teachers, and I are doing everything we can to make sure you have a good education. But you've got to do your part, too. So I expect all of you to get serious this year. I expect you to put your best effort into everything you do. I expect great things from each of you. So don't let us down. Don't let your family down or your country down. Most of all, don't let yourself down. Make us all proud.

   — By President Obama

Children can spend hours a day looking at computer screens and other digital devices. Some eye doctors say this leads to an increase in “computer vision syndrome(电脑视力综合症).”
Nathan Bonilla-Warford is an optometrist（验光师）in Tampa, Florida. He has seen an increase in problems in children. “A lot more children come into the office either because their parents have noticed that they have headaches or red or watery eyes or discomfort, or because their nearsightedness appears to be increasing and they’re worried,” he says.
Dr. Bonilla-Warford says part of the problem is that children may be more likely to pay no attention to early warning signs than adults. “Even if their eyes start to feel uncomfortable or they start to get a headache, they’re less likely to tell their parents, because they don’t want to have the game or the computer or whatever taken away,” he explains.
He says another part of the problem is that people blink（眨眼）less often when they use digital devices. He says, “A person who uses an electronic device blinks about one third as much as we normally do in everyday life. And so that can result in the front part of the eye drying and not staying protected like normal.”[来源:Z.xx.k.Com]
Eye doctors offer suggestions like following which is known as the 20/20/20 rule. That means every twenty minutes look away twenty feet or more for at least twenty seconds from whatever device you’re using.
Other suggestions include putting more distance between you and the device and using good lighting. Of course, another way is to spend less time looking at screens. Many experts say children should spend no more than two hours a day using digital devices—with no screen time for children under two.
But not all eye doctors have noticed an increase in problems in children. Dr. David Hunter, from Children’s Hospital Boston, has not seen an increase in his practice. “While it is possible to develop fatigue looking at screens for a long period of time, there’s certainly no proof that it actually causes any damage（伤害）to the eyes.” he says.

    Last year my English class was difficult1.first of all, it wasn't easy tor me to understand, what the teacher said .To begin with, she spoke too quickly, and I couldn't understand every word. Later on, I realized that it doesn't matter if you don't understand every word2.I was also afraid to speak in class. because I thought my classmates might laugh at me. I couldn't always make complete sentences, either. Then I started to watch English-language TV. 3.这很有帮助. I think that doing lots of listening practice is one of  the secrets of becoming a good language learner. I also found English grammar very difficult. 4.50 I decided to take lots of grammar notes in every class. Then I started to write my own original sentences using the grammar I was learning It's amazing how much this helped. 5.现在我喜爱学英语
