Tigers are very strong and scary. We may see tigers in Europe, Asia and America in the mountains. The tigers live far away from {#blank#}1{#/blank#} houses. They eat birds, hares (野兔) and other small {#blank#}2{#/blank#}. In the day they hide in the dens (巢穴), and at night they go out {#blank#}3{#/blank#} food.

    In {#blank#}4{#/blank#} when tigers are hungry, they will become very {#blank#}5{#/blank#} But now, people cut down many {#blank#}6{#/blank#}, so tigers are losing their homes. Also, some people kill tigers to get {#blank#}7{#/blank#} fur. Some people even buy things made {#blank#}8{#/blank#} tiger bones (虎骨). So the number of tigers {#blank#}9{#/blank#} getting smaller and smaller.

    Animals are our {#blank#}10{#/blank#} friends. In order to protect them, we must build many natural reserves. And we must stop people from hunting.

    Benjamin Banneker was born a few months before another great American—George Washington. Benjamin was black, but he was not a slave (奴隶). He and his mother and his grandmother were free. Benjamin's grandmother came from England. In America she got a job and worked for many years to pay for her boat trip across the ocean. After working many years, she saved enough money to buy a farm. Benjamin lived with her for a while. She taught him to read, write and do arithmetic (算术).

    Benjamin's neighbours knew that he was clever. They were not surprised when he built a large wooden clock. He made each piece after studying a small pocket watch. The clock made him famous, for it was one of the first clocks built in America. People from other places began to send hard problems of all kinds to Benjamin to settle.

    Thomas Jefferson heard of Benjamin Banneker's ability to settle hard problems. He asked Banneker to help build the city that was to be the capital of the United States—Washington, D.C. Banneker worked hard on the plans for the city. He marked where the streets and buildings—the Capitol (美国国会大厦), the White House, and many other places should be built.

    Later, L' Enfant, the Frenchman who had designed the new city, had a quarrel, and went back to France in anger. He took all of the plans away. The workmen couldn't build without any plans to follow.

    For a while it seemed that the plans for the capital might have to be changed, but Benjamin Banneker remembered the plans he had helped draw. He drew each again as he had built each piece of his clock.

    If it weren't for Benjamin Banneker, Washington,

    D.C might look very different from the way it does today.

    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.

What would you do if you see someone hurt badly? The following will help you to learn some important skills to give casualty (伤员) first aid.

{#blank#}1{#/blank#}

The first and most important thing you must do is to make sure the place is not dangerous. Can you see anything that might not be helpful to you? Can you hear anything that could be dangerous?

{#blank#}2{#/blank#}

When you see someone has been hurt, you may feel scared. If you feel yourself starting to be nervous, try to calm yourself down. For example, talk to people you trust about what happened, and you'll be relaxed.

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

When someone needs first aid, talking to him will help him to stay calm and feel safe. Even if he does not answer you, you should still tell him what you are doing. It will let him know that you are helping him.

{#blank#}4{#/blank#}

Sometimes, the casualty will need more help than you are able to give. The best thing you can do is to phone some people for help. They can give you some useful advice or offer you some help.

{#blank#}5{#/blank#}

There are also many other things to do. Try your best to help the casualty. Asking people around you for help is really better than waiting for doctors. Besides, you can also try to keep in touch with his families and friends.
