There are some injuries that are common to all types of extreme sports. The following are some of the important things to do to prevent extreme sports injuries. {#blank#}1{#/blank#} But they can definitely minimize the risk of injuries.

    Warm up.

    {#blank#}2{#/blank#} They include a combination of cardiovascular(心脏血管的)exercises, strength drills and stretching. Cardiovascular exercises increase body temperature, heart rate and blood circulation, which is required for further movement of the body. Strength drills increase the stamina of the body, while stretching warms up the muscles preparing them for sudden forceful movements. {#blank#}3{#/blank#} It also plays an important role in boosting the team spirit for a team sport. A warm-up session should last for at least 20 minutes and it can extend up to half an hour.

    Avoid overworking.

    There are some people who do not exercise their body for the sport on a regular basis and perform a week's task in a day or two. {#blank#}4{#/blank#} They do not realize the effect of overworking during the performance and keep doing it until they feel extremely tired. Apart from the actual sport, one should also avoid overdoing the warm-up exercises before the activity.

    {#blank#}5{#/blank#}

    Just as warming up is essential before any rigorous(充满活力的) physical activity, cooling down the body after playing a rigorous sport is also a significant part of physical conditioning. When you are done with your sports session, you can conclude with some walking, jogging or light running. Slight stretching exercises, focusing on specific muscles, will also be useful for cooling down the body.

A. Cool yourself down.

B. Look for a coach to train you.

F. You should also be careful about your clothing selection for warmth and protection.

G. Warm-up exercises are very important before you begin any sports practice.

Get a Thorough Understanding of Oneself

    In all one's life time it is oneself that one spends the most time being with or dealing with. {#blank#}1{#/blank#}

    The UN has recognized the contributions of volunteers on Dec. 5, International Volunteer Day. Here, the four things are offered to consider before taking the leap into overseas volunteering.

    Choose your organization carefully

    {#blank#}1{#/blank#} volunteering may be a fundraising mechanism（筹资机制）for a development project. For others, volunteering is fundamental to their programs, and those serving take on professional roles in longer-term development.

    {#blank#}2{#/blank#}

    Volunteers want to help and make a difference, but most know this isn't a purely selfless act. You will learn new skills, broaden your horizons and come to better understand yourself and the world.{#blank#}3{#/blank#} Reflect on your motivations. You want to help reduce global poverty or protect the natural world, but what else? Have you always wanted to travel, but not as a tourist? Work with kids? When you understand your motivations, you'll be in a better position to choose the option that is right for you.

    Work alongside the local community

    Often times, travelers volunteer in isolation（隔离）from the local community in which they are working in.{#blank#}4{#/blank#} This enables you to ensure you are committing to a project that promotes long term and sustainable change.

    A volunteer trip is just the beginning

    {#blank#}5{#/blank#}Further ignite（点燃）the global change maker in you by taking your experience one step further when you return home. Spread the message of your transformative experience to others, helping to spark the change within them.

How to read more and learn more

These days,more and more Chinese people enjoy sending and receiving messages on the phone.It can help them to get the latest news and communicate with friends.But I think I should read more books besides the textbooks;the more,the better.It can broaden my mind and improve my language skills.{#blank#}1{#/blank#} Here are some tips for you.

Clear your purpose for reading.

{#blank#}2{#/blank#} Most people read for two main reasons,pleasure or knowledge.Clearing about your reading purpose can not only help you choose the books you really need to read,but also remind you why reading the book is important to you,so you will keep reading and complete the book faster.

{#blank#}3{#/blank#}.

No matter what you are reading,it is important to enjoy what you read.Your friends may introduce you the books they love,but those books might not necessarily be the ones you enjoy.

Give up books that you don't enjoy.

You may have chosen books that you are interested in,and they are right purpose.But while you are reading them,there may still be some books that you don't enjoy reading.Whenever you realize that you aren't enjoying the book you are reading,give it up.{#blank#}4{#/blank#}.

Set a reading goal.

It is interesting that I read the books borrowed from libraries faster than those I bought.The reason is that the books I bought don't have a due date!I don't need to return those books.

{#blank#}5{#/blank#} Before you read each book,ask yourself what time you need to complete this book by.

A.Read only what you are interested in.

B.Read the books borrowed from others.

C.Remember reading shouldn't be a burden.

D.Of course,it also can help me to get good grades.

E.We need to get the latest news and communicate with friends.

F.Before you start reading,ask yourself why you are reading this book.

G.Having a reading goal helps you work out how much reading you need to do in a week or even a day.

Physicist and Nobel Prize winner Richard Feynman developed a clever learning method known as the Feynman Technique. It involves explaining what you're learning to others. By teaching what you've learned from memory, you engage in active recall.  {#blank#}1{#/blank#} It also ensures that you understand the topic, because you can explain an idea if you truly understand it. The technique consists of four repeatable steps.

To begin, choose a concept or a topic you wish to fully understand. {#blank#}2{#/blank#} The more interested you are, the faster you'll grasp it. Moreover, a personally interesting topic will keep you motivated and engaged.

{#blank#}3{#/blank#}  Write notes and explain it in a way that makes sense to a five-year-old. If you'd rather avoid actually teaching someone, you can just teach it to an imaginary audience. But it works much better if you use a real person. They'll be able to let you know when something isn't clear.

While teaching, you may discover gap s in your understanding. {#blank#}4{#/blank#}  Review your notes, reread books, or seek external help to ensure you have a complete understanding of the context before moving forward.

Now that you fully grasp the concept, test your understanding by trying to teach it to another person. This will help you identify any remaining areas of uncertainty you need to revisit.

The Feynman Technique is a great way for kids and grown-ups to learn.  {#blank#}5{#/blank#} You need to actively think about the problem instead of passively reading or listening to someone else. However, with great efforts in mastering this method, you'll see your learning results improve quicker than ever before.

A. It is mentally demanding.

B. This helps the information stick in your mind better.

C. Teach it to a five-year-old, who would give you direct feedback.

D. Your curiosity about it will determine the pace of your learning.

E. Once you have chosen a topic, you can teach it to someone else.

F. Active engagement plays a key role in promoting deeper learning.

G. When this happens, refer back to the original material for the missing pieces.
