A strong memory depends on the health and vitality（生命力）of your brain. They say that you can't teach an old dog new tricks，but when it comes to the brain，scientists have discovered that this old saying simply isn't true. 【小题1】

Give your brain a workout. Memory, like muscular strength, requires you to“use it or lose it”. The more you work out your brain, the better you' ll be able to process and remember information. 【小题2】

Don't skip the physical exercise. While mental exercise is important to brain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brain stay sharp. It increases oxygen to your brain and reduces the risk of disorders that lead to memory loss.

Get enough sleep. There is a big difference between the amount of sleep you can get now and the amount you need to function at your best. 【小题3】

Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys brain cells. Studies have also linked stress to memory loss.

Have a laugh. 【小题4】 That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specific areas of the brain, laughter involves multiple regions across the whole brain.

【小题5】 Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains,“healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat — it's also what you don't eat.

   A few changes about how a teacher runs a classroom can make a huge effect on how concentrated students will be in that classroom. It’s an issue every teacher has to face. 【小题1】 Here are just a few of my methods.

●Rearrange (重新布置) Seats.

I did the seat rearrangement because class conversation had become dull, and students just seemed to be there but not actually there. 【小题2】 I had all of my students pick new seats at the tables. The rules were simple. They could not sit with more than one other person they’d already sat with, and it had to be at a different table.

● Take over a Lesson.

Once in a while, it can be fun to let the students take over a lesson in a unit. Let them become the teachers, and the teacher becomes the student. You can provide the topics they need to cover. 【小题3】

● Have Open Projects.

Open projects have been very successful in my class. 【小题4】 I used to dictate (指定) every part of my project tasks. Students would ask to do things a little differently. And I’d give in, surprised that their ideas were better than mine.

● 【小题5】

Sometimes teachers forget to bring the fun to the classroom. We try so hard to cover the courses for our students until they break down. Sometimes it’s good to just set things aside for a day or two and have some fun.

Keep Calm During the Hard Times

When life gets hard, sometimes it's not easy to control yourself and not to sink deep into the bad feelings. Have you ever wondered how some people can be so calm during the hard times？【小题1】 Here are four things you can do to get through hard times.

Cry if you need to-for a while. Some people like to control themselves.【小题2】 If you do control them, it's like holding a ball under the water. You can do it for a while, but it will finally come back to the surface. So have a good cry once in a while to help you think more clearly.【小题3】 Lost in the bad emotions, we won't change anything. Let's say you just lost your job. Maybe it is a shock. After crying, then you should make the decision to put your calm hat on. Start to find new jobs. Then do something.

Ask for help. Unluckily, a lot of people think that asking for help is a sign of weakness. It's not!【小题4】 Nowhere! Having other people support you will make you feel like you have more power than before.

Believe that things will get better. If you don't believe that things will change, then they won't. I always love Henry Ford's words, "Whether you think you can or you think you can't-you are right." If you think things will get better, then they finally will. If you think they won't, then they won't.【小题5】

Stay calm when life gets hard. If you practice these steps on a regular basis, sooner or later it will become second nature to you.

   When I was seven years old, I got the greatest Christmas gift ever. 【小题1】   Now I realize I actually have the power to be a superhero. I may not be able to fly, but I can make a difference to someone's life. We all have the power to be a superhero to someone. Here are four ways you can be a real-life superhero.

  【小题2】 Think about what it is. It could be your support, time, advice, a small gift or a thank-you card. Sometimes, even just the most harmless message can bring someone out of darkness and into the light. It's something that you give that can help others.

Keep yourself healthy. 【小题3】 Look after your body and helping people will be easier. You'll have a clear mind and energy to achieve any task in your way.

Pick your fight. Every superhero has a battle. It's something that drives them to be the person they are. 【小题4】It could be anything such as working towards helping reduce the number of homeless people on the street. The fight does not need to be big, but it needs to be powerful.

Make someone's day. Real-life superheroes try to improve the lives of all the people they meet. 【小题5】 You can also try your best to absolutely make someone's day every once in a while. The people who get your help will thank you for it.
