    On a very hot day，it can be hard to know what to do to feel good．If we run around，we may feel dizzy and sick to our stomachs．This is because our body can't get rid of the extra heat．However，if we just sit and do nothing，we may feel restless and bored．Are there things we can do to feel good when we are hot? Yes! Playing in water is one way to feel cooler．Of course，people with a pool，river，lake or ocean nearby can play in the water very conveniently．People don't have these can still play in water too．Taking a cool bath or shower can feel good on a hot day．On hot days，you can lose two gallons(加仑)of water in one day，so many doctors agree that you should try to drink at least 16 glasses of water to keep the water balance in your body． Mixing a little juice into your water is a good way to help you drink plenty of water．The food we eat also makes a difference in how we feel in the heat．Cold foods，such as ice cream and drinks with some ice can cool down our bodies．Fruits and vegetables are easy for the body and refreshing．Plan a healthy menu for a hot day．

    Wind power is a very clean source of energy. This is how wind power works. Wind makes windmills spin (旋转). When the windmills spin, they make electricity. Then we can use the electricity.

    A lot of people think that wind power is new, but that's not true.

    For thousands of years, people have used wind to sail boats and move water. We still do those things today, but these days we mostly use wind power to make electricity.windmills

    Wind power is a very popular source of energy. Most people think that we should use it more and more. First of all, it's clean. Windmills don't pollute the environment at all. Second, we can use wind power forever. After all, we will always have wind. Also, wind power is cheap, and it's getting even cheaper.

    A lot of people don't understand wind power very well. They believe that there are problems with wind power, but many of those problems are not real. For example, some people say that windmills are dangerous for birds. They used to be true, but it isn't true anymore. Old windmills killed birds because they spun very fast. New windmills spin slowly, and they aren't dangerous for birds.

    However, there are real problems with windmills. One problem is that many people think windmills are very ugly. This is a problem for people, because windmills are often in very pretty areas. Also, wind doesn't blow all the time, so we can't use wind power all the time. Finally, windmills are noisy.

    Wind power is becoming more and more common. Right now, more than 80 countries use wind power. About 2.5 percent of the world's power comes from the wind. For some countries, that number is a lot higher. Wind power gives Denmark more than 25 percent of its electricity.

Summer is just around the corner. When you spend time outside, you'll experience the hot weather. According to the {#blank#}1{#/blank#}, we are seeing the hottest summer. It's more important than ever to know how to keep cool.

Being hot is really {#blank#}2{#/blank#}. Sometimes, it can lead to illness. That's one danger of long heat waves. If nighttime {#blank#}3{#/blank#} also rise, they give people less time to cool down.

Your body responds to heat in many ways. One is by sweating. Another is by releasing heat. Your body works hard to stay cool. Staying cool uses {#blank#}4{#/blank#}. It is necessary to help your body deal with heat.

Frustration (挫折感) is a feeling that is common to nearly everyone: so much to do, so little time. Another year gone by with nothing done, you find all last year's resolutions haven't been realized. Neither did you run that marathon (马拉松) , nor did you learn the guitar. But never mind, things will be different in a new year. This time you will try to finish them through the wind and rain, right? Sadly in Mid-February, 80% of you will have already given up your plans. 

I have always considered the word perseverance (毅力) means such serious suffering (痛苦) and loneliness. Luckily, there is a simple way to achieve success by changing your daily habits. 

In his book, Atomic Habits, author James Clear tells the way of keeping perseverance. He suggests that, if you truly wish to make big changes to your life, the best way is not by making big New Year's resolutions, but by making small changes to your daily habits. 

Getting a small change day by day can help you achieve your big goal. In short, you are your habits and if you have some respectable habits, you will achieve great things. Start slowly and don't worry about others'opinions. You are in competition with yourself. So if at first you don't succeed, fail and fail again, make some changes and you'll succeed. 

Trying to stay healthy seems to be a difficult thing for us. To have {#blank#}1{#/blank#} healthy lifestyle, there is no {#blank#}2{#/blank#}（good） way than encouraging the whole family to work together for it. When others do the same {#blank#}3{#/blank#}（activity） as ours, we can encourage each other to keep doing it. If {#blank#}4{#/blank#}（your） get your family to be interested in doing exercise and eating {#blank#}5{#/blank#}（healthy）, you will be fit and healthy. 

When you go shopping, only buy healthy food. Buy vegetables and fruit rather than junk food like chips. Try different kinds of food and try {#blank#}6{#/blank#}（eat） at home more often. 

Don't think {#blank#}7{#/blank#} food as some kind of entertainment （娱乐）. We may often meet our friends for lunch. In fact, there are many other things you can do with friends. How about {#blank#}8{#/blank#}（meet） friends for a football game rather than meeting them for lunch? You can still eat, {#blank#}9{#/blank#} the activity doesn't have to be focused （集中） on food. The food is less important than the fun activity. 

Looking after your health should not be boring. {#blank#}10{#/blank#}（start） now. 

There are many different kinds of birds all over the world. Do you know the bald eagle(秃鹰)? It's very interesting that the bald eagle is not really bald. It has feathers on the head. Bald eagles are large birds. As birds, they can live for a long time.

 Bald eagles like eating fish. People often see them flying down from the sky and catching fish out of the water quickly. They like living near open water because they can easily find fish there. Bald eagles also eat some small animals. Bald eagles stay in most parts of North America. They are in the southern states and Mexico all the way to Canada and Alaska. However, a large number of bald eagles live in Alaska and Canada.

 The mother bald eagle lays one to three eggs each year. Both parents take care of the eggs. After about35 days, the baby birds break out of the eggs. The young eagles are ready to leave home for food when they are about 13 weeks old.

 Hunting and pollution made bald eagles in the United States in danger. Some strict rules to stop hunting the eagles and to cut pollution have allowed the bald eagles to come back.

 All in all, people should try their best to help protect the birds. They are human beings' good friends. Look up in the sky the next time you are out in nature. You might see one of these wonderful birds in the sky.
