The ostrich is the largest bird in the world. The ostrich is found in nature in Africa, but it is raised all over the world for its meat.

    The ostrich is a unique（独特的）looking animal. It has long skinny legs, a big body with small wings, a long neck, and a dangerous long beak（喙）.Even though it has wings, it can't fly. But they aren't completely useless either. They help a lot with balance when the ostrich is running at full speed and needs to change directions. The ostrich usually weighs between 200 and 300 pounds and can grow to 9 feet tall. Its large body is covered with feathers.

    The ostrich is famous for its speed on the ground. Its powerful legs allow it to reach speeds of 40 miles per hour! Ostriches can also use their strong legs to kick any enemy or even kill a human or a lion. However, in most cases the ostrich just use its speed to run away from any danger.

    Ostriches eat whatever they can find. This includes plants ,insects, and small animals like lizards. They often live in groups. A group will have around ten birds, but some groups even have 100 birds. This way the whole group can help to protect the eggs. Ostrich eggs are the biggest eggs of any animal at an average of 3 pounds.

    Ostriches don't actually put their head in the ground as many cartoons like to show. What they really do is to lie down and put their head and neck flat on the ground to hide. From a distance all you can see is their body, so it appears as if they have put their head in a hole in the ground. Ostriches can not only kick with powerful feet, they are also armed with 4 inch long claws（爪）on their feet.

    Drones are like airplanes, only without a pilot. No one without a pilot's license should be allowed to have one.

    Something bad or unexpected can happen when people send up a self-controlled flying machine like a drone without knowing how to really control it. Drones can become flyaways, and can be caught up on a jet stream (喷气流) and blown away.  A falling drone can do much damage (损害) to buildings and people.

    Though drones can be harmful, they can be very helpful.

    At a sports event, drones can be used to give the spectators (观众) a view from above or help coaches see how their players are doing.

    They are also becoming a useful tool for firefighters, helping them find and fight wildfires. Drones can watch secretly on populations of animals in the wild, especially endangered ones.

    In some faraway places in the world, drones are the fastest way to send medicine to people who are in great need of it.

    Some people think drones can only be used by governments to help when needed. Others think that if rules are obeyed, there should be little risk to people and property (财产).

    Drone makers say drones are exciting new technology and that the future will be controlled by them.

    Today, people are paying more and more attention to improving their health through sports and exercise. But some of them have some wrong ideas about it.

    In fact, the best meal before games should have carbohydrates(碳水化合物). Foods like potatoes, bread, bananas are rich in it, but chicken and meat are not. Carbohydrates are the best and most easily used form of energy. The energy that you get for today's game is from what you ate yesterday!

    No. Morning is a good time to exercise, but it may not be suitable for you. If an afternoon or evening period suits you, and you enjoy the feeling of getting healthier, you can choose any time to exercise. There is no fixed time for you to exercise.

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

    The fact is that you must have some water during breaks when you exercise. And after exercising, you must have enough water. If you don't drink enough water, then you'll probably get headaches and feel tired.

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

    False. Exercising the same body part every day is the fastest way to cause problems. To improve strength, you want to work your muscles(肌肉) hard, but then you need to give those muscles a day of rest. Too much exercise can cause serious problems to muscles.

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

    Wrong. We usually connect those big muscles with bodybuilders(健美运动员), but girls don't have enough male hormone(雄性激素) to make their muscles big like men. Strength training is a good way to make their muscles strong for girls.

    One of the easiest ways to keep healthy is to do jogging. Jogging is the name for very gentle (平和的) running-it is just a little faster than walking.

    First jog slowly 20 meters, and then walk 20 meters. Little by little if you are not feeling very tired, you may jog more and walk less. Finally, jog the whole way. It will be easy for you to start jogging for 15 minutes twice a week. Then slowly increase this to 20 ~ 30 minutes every day. The longer you join in jogging, the more you will enjoy it and the healthier you will become. Some people like jogging alone and others enjoy doing it with friends. Jogging in groups makes people keener (更热心的) because you just can't stay in bed while there is a group of friends waiting outside.

If you want to start jogging, prepare a pair of comfortable shoes and a determined(坚定的) mind.
