As your schooldays start, you might feel a bit worried or nervous. You might feel kind of unhappy or angry.     1    . But would your favorite superhero have these same feelings?

Behavioral（行为的）scientists studied what they call the “Batman Effect”（蝙蝠侠效应）in children.     2    . Kids won’t feel as much nervous as before if they think themselves like a strong person such as a superhero like Batman.

For example, if you feel nervous during an exam, try to think that you are Batman. You may find that you can get less stress（压力）from this situation and feel more confident.     3    . Thinking like to be strong makes us feel strong, and that carries over to how we act in real life.

    4     Anyone who you like can give power（力量）you need to get through difficult times, or tell you how to act in bad situations. Movie stars, famous painters, even our own parents——anyone can be our “Batman”.

For example, when it comes to how I act with others, I like to tun to Mister Rogers for power.     5    . I try to act the same way toward other people as much as I can and I will be happy with myself after I solve the problems well.

Failure (失败) is a part of life since our earliest moment of life. We often think of failure as something bad.     1     which is neither bad nor good. However, what can help us when we fail?

Don’t be afraid of failure

Failure is how we learn. If we never fail at something, we probably haven’t learned all that life has to teach us. So failure means taking something away from the experience.

Never stop trying

Trying or learning something new is often half the battle (战斗), don’t give up trying. You may get disappointed because of failure.     2

Nobody can be our safety nets all the time in our lives. Only we can act as our own safety nets. Become your own best friend, do everything that you can possibly do for yourself.

Don’t look back

We spend too much of our lives looking back.     4     Spend just 10 percent more of your time looking forward to what life holds for you in the future, and I’m sure that you’ll find yourself in a better position.

【推荐1】Watching videos is becoming a part of our daily life. Most of us like to watch them to relax or kill the time. Some videos are just for fun, some are news and some are short films ...

Two retired (退休的) teachers are well-known for making short videos. They make them to share knowledge.

Wu Yuren is a retired physics teacher. She has become known as “Grandma Wu” by making videos. She uses a humorous and easy-to-understand way to do physics experiments (实验) online. She is good at using everyday tools to experience the magical world of science. She wants young people to be curious about daily life. In this way, young people enjoy finding out the knowledge of science hidden in our life. Wu is more than 70 years old now but still works hard.

Wang Pinxian is an 87-year-old marine geologist (海洋地质学家) and teacher at Tongji University. During the past two years, he has used his videos to share his knowledge of the sea. He often studies things like the secrets of the Bermuda Triangle (百慕大三角) and whether there are sea monsters (怪物) in the sea.

These videos have been popular and thousands of people have watched and shared them. Many fans express their thanks for the chance to learn new things and stay in touch with the world around them.

Their videos are like “classrooms without walls and universities without barriers (障碍)”. The two gray-haired people have created real energy to society through their actions.

【推荐2】We go to school every day to become a better person. So how can we become better and start changes in our own life? Perhaps we can get something from the US First Lady Michelle. Obama-the wife of the president Obama. During her visit to China, from March 20-26, Mrs. Obama shared her ideas on education with students.

The first lady encouraged (鼓励) Chinese students to study hard and get a good education. In Chengdu No.7 High School, she told students that having poor family doesn’t matter if you have perseverance (毅力).

Ms. Obama said her family was not rich. Like many Chinese students, her parents had big dreams for her. She felt the pressure from her parents and worked hard to make them proud.

Persevering was not easy, though. Sometimes she had to wake up at 4:30 a.m. and study late into the night. “But whenever I got tired, I would remember something my mother always told me.” She said: “A good education is something that no one can take away from you.”

Mrs. Obama also visited Xi’an and when she was in Beijing, she encouraged Chinese students to study in other countries to open their eyes in her speech at Peking University.

“As the Chinese saying goes: It is better to travel 10,000 miles than to read 10,000 books,” she said. It’s not enough to get good grades in school. It’s also important to have real experience with languages, cultures and situations different from your own.
