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.

   A hobby is an investment of time. It also can be an investment of money and commitment. Many people choose to develop more than one type of hobby. It can be necessary to select the hobby that is right for you. 【小题1】

Hobbies are usually an activity of some sort that brings out a certain skill that you have. When you have a talent like painting or woodworking，it can be easy to determine which hobby suits your skill. 【小题2】 Skills can be developed and challenged as you go along. It is not a necessary requirement. A hobby is fitting because you love it，not because you're a professional at it.

Some people particularly enjoy taking part in hobbies that they can do in a group with others. It can be a lot more fun to become a member of a hobby group than to sit alone in your basement. 【小题3】 It's important to share interests and networks with other hobby enthusiasts that do what you do.

Hobbies are generally an activity that you undertake（着手做）because of the joy it brings you. Of course many people have discovered the joy that also comes with a hobby that earns you a living. 【小题4】 Just make sure you make the choice that fits your lifestyle and personal preference.

【小题5】 But most of the skilled hobbies like art，building or writing have a series of lessons or tutorials that you can take to further your skills. In some cases it's really a good idea to take lessons，especially if you are clueless as to where or how to begin. Step by step books for most hobbies can often be found in bookstores as well.

   Undoubtedly, the best way to prevent illnesses of the mind is to exercise the brain. Here’re some great exercises to sharpen your mind.

Never stop learning. 【小题1】 One way is to take classes online through websites like Coursera, org or Edx. org, where you can take courses from the top universities for free. Perhaps you would like to learn a new language. 【小题2】 There are wonderful language programs available through RosettaStone. com and Duolingo.com which offer many lessons to choose from.

Read something everyday. Reading itself is a wonderful brain exercise. Make a point to read something every day. It could be a newspaper, book, blog or magazine, but the more informative it is, the more of a workout it will be for your thinking cap. 【小题3】

Exercise your body. Exercising your body affects your strength, mood and fitness. Exercise excites the nervous system and causes you to perform at a higher level.

【小题4】 Communicating with others on topics of common interest is a great workout. Talking about in-depth topics like headline news and political interests exercises your ability to pay attention and focus. There are always many like-minded people who enjoy the same hobbies or share the same beliefs.

Play games. The act of solving problems and figuring out puzzles is excellent for keeping your brain in shape. 【小题5】 Solving math equations or word puzzles, and even just a quick game of Bubble Witch will do wonders for your thinking processes.

   Our memory naturally drops as we age. We depend on our memory to perform our daily tasks well and do our jobs properly. 【小题1】 . Nothing is more embarrassing than forgetting vital information at a gathering. But there are some ways we can do to make it as sharp as ever.

Sleep Well

This is very important if you want to keep your good memory until you grow old. You must give your brain enough rest and sleep so that it can regenerate more cells where it can store more information. 【小题2】.

Eat Healthily

【小题3】. Eating avocado and broccoli stimulates（促使）blood flow to the brain. Have more beans which contain folate（叶酸）—a vitamin B that figures well in brain development. Adding nuts and beans to your daily diet can also contribute to a healthier memory.

【小题4】

Don't think that you are too old to learn new skills. Try learning a new language or even playing an instrument. Start attending baking or painting classes.

It's not really the skill that you choose but in the fact that you focus on it for regular periods of time and find it interesting.

Exercise

【小题5】. When we exercise, we increase blood flow to the brain, increase the production of newer and younger cells and protect the brain cells from any kind of damage. Exercise can do a lot of wonders to our body, so you'd better start exercising now before it's too late.

Hello，everyone. It is a great honor for me to speak here. The topic of my speech is the significance of reading.

That's all. Thanks for your attention.
