    Have you ever considered starting a fitness program? Since exercise can reduce the risk of diseases, improve balance, help lose weight, better sleep habits and even make you confident, you should start a fitness program in the following steps.

    Test your fitness level

How many meters can you walk or run in one minute? How much time does it take you to swim 50 meters? What is your heart rate (心率)? The data (数据) of your fitness level can help you know what activities you need.

    Design your fitness program

You may have begun your daily exercise. But a personal plan helps more. First, you should have your fitness goals (目标). For example, what do you want to look like, to be slimmer or quicker? A balanced plan will help you start low, progress slowly, do right activities and even allow you to recover (康复) if you get hurt.

    Prepare things needed for sports

You need something practical, enjoyable and easy to use. It could be a pair of trainers, a volleyball or a bicycle. You can also download fitness apps (应用程序) on your mobile phone to measure distances, calories burned or your heart rate.

    Take action

Now you're ready for action. When you begin, don't always try tough tasks. Listen to your body and reduce exercise time if necessary.

   Monitor your progress

Test your fitness level again six weeks later. If you have achieved your goals, increase exercise time to continue improving.

Starting an exercise program is an important decision. By planning carefully and acting step by step, you can have good health.

How to learn English

How can you learn English well? Here are my suggestions. 

……

I hope these suggestions can help you. 

Nowadays, a new method is used to decide who are the top students in school. The best students are those who not only get high marks, but also follow the rules and the behavior standards (行为标准) for middle school students. {#blank#}1{#/blank#}

Tell the truth. Have you ever copied someone else's work on an exam? {#blank#}2{#/blank#}That's not something an honest student should do. If you have played computer games for two hours in your room, don't tell your parents you were doing homework. 

 {#blank#}3{#/blank#} It would be more fun when more people work together. Did you fight with your teammates when your basketball team lost? Only working together can make your team stronger. Be friendly to the people you are with. Try to think of others instead of only yourself. 

Be open to new ideas. {#blank#}4{#/blank#}Perhaps you'll discover Earth II someday. Don't look down on new ideas. Everyone's ideas are important. You should welcome them, because new ideas make life better for everyone. 

Use the Internet carefully. Some websites on the Internet aren't for kids, so make sure to visit the web pages that are good for you. {#blank#}5{#/blank#}You'd better visit the websites with your parents together.

Do you know cosmic radiation(宇宙辐射)? Have you ever seen the auroras ( 极 光 ) in the sky? Cosmic radiation creates these pretty lights in the North and South Pole areas. It seems that cosmic radiation is a beautiful gift from space. But for some people, it can be dangerous.

A 53-year-old flight attendant(空中乘务员) in South Korea, who spent about 1, 022 hours flying each year, passed away due to cancer. His death was thought to be connected to great exposure (暴露) to cosmic radiation. During his lifetime, nearly half of his flights crossed the areas in and around the North Pole, where cosmic radiation is very strong.

Cosmic radiation from space is hitting Earth nonstop, coming from both the sun and other stars in the sky.

____ . Earth's magnetic field (磁场) and atmosphere (大气层) protect us from most cosmic radiation. The magnetic field is the strongest near the equator and the weakest at the poles. People living at higher latitudes (纬度), like in Heilongjiang province, are exposed to a bit more cosmic radiation than those living at lower latitudes, like in Hainan province. Also, when you go higher in an airplane, the thin atmosphere increases exposure to cosmic radiation.

Cosmic radiation can create health risks. However, what makes cosmic radiation dangerous also makes it useful. The high speed and energy of cosmic radiation have provided wonderful ideas for treating some cancer. Scientists can now produce man-made radiation similar to cosmic radiation. Compared to the present ways of treating cancer, it can work better with less harm to healthy parts of the body around them.
