【推荐1】Everyone must go to bed early and get up early, or we won’t be healthy and clever.

Is this true? Perhaps it is. The body must have enough sleep. Children of your age need ten hours' sleep every day. If you don’t go to bed early, you won’t have enough sleep. Then you can’t think properly and can’t do your work properly. You’ll not be clever.

Some people go to bed late and get up late. This is not good for them. We must sleep at night when it is dark. The dark helps us sleep soundly. When the daytime comes, we must get up. This is the time for exercise. If you lack exercise, the body will become weak. Exercise keeps a strong body.

Exercise helps the blood flow around inside the body. This is very important.   Blood takes food to all parts of our body. The brain also needs blood. If we keep our body healthy and take exercise, we can think better.

【推荐2】It seems that Microplastics (微塑料) have entered every part of the planet today, including rain over the Rocky Mountains. Recently German scientists have even found them in Arctic (北极) snow.

Microplastics are pieces of plastic smaller than 5 millimeters (毫米). Sadly, scientists found 1,800 pieces of microplastic per liter (公升) of snow.

Scientists have been puzzling over how this flood of pollution makes its way to the Arctic. A new study from Germany finds that microplastics in the snow come from the air. They fall off and are moved by the wind, just like dust (灰尘). They mix with ice in the air and fall in the Arctic as snow.

Finding these plastics in Arctic snow means that we may breathe them in. An even higher amount of microplastic was found in the snow around cities.

Are they bad for us? Scientists cannot answer this question for now, according to the World Health Organization. We do know that our bodies cannot take in “large” pieces of microplastics. However, if the plastics are small enough, they can find ways into our bodies and stay there for a long time, they can be bad for our health.

Microplastics have also been found in rivers and oceans around the world. The research has found that they run over long distances and into oceans, doing harm to ecosystem (生态系统) along the way. They start in our wastewater, when we wash clothes with plastic fibers (纤维). The wastewater then runs into rivers and out to sea. Then they are eaten by sea animals in the sea. If people eat these animals, it means that we’re eating the plastic as well.

Have you ever been to the Dead Sea, one of the most famous natural wonders in the world? Have you ever considered why it is called Dead Sea? Does it hold life? Can people swim there? With all these questions in your mind, let’s know something about it!

The Dead Sea is actually a lake in the Middle East. At four hundred meters below sea level, it’s the lowest point on Earth. It lies between the borders of Jordan, Israel, and the West Bank. It’s about 80 kilometers long, 11 kilometers wide at its widest point, and 377 meters deep at its deepest. The lake is surrounded by hot, dry desert on all sides.

Since it’s in a hot desert, water evaporates (蒸发) faster than the lake is refilled. And the area is lower than all the land around, the water can never flow back out, it can only evaporate. And that’s what happens-water continually evaporates. In fact, so much water is evaporating from the Dead Sea, it often looks like there’s a cloud of fog hanging over the lake. Anyway, as the water evaporates, it leaves behind the salt and minerals (矿物质). The water in the Dead Sea is almost six times saltier than ocean water!

Because the Dead Sea is so salty, almost nothing can live there, except for bacteria and one type of algae. Any fish or freshwater animal that gets washed into the lake dies almost immediately. And the shores are covered in thick salt crystals (结晶), so animals can’t even live near the lake either. That’s why it’s called Dead Sea.

Since it’s so salty, why do people go there to cover themselves from head to toe with its mud? Actually, those minerals are supposed to be really good for your skin. No wonder lots of spas and health resorts have been built in the area. Though the water in the Dead Sea is so salty, it is totally safe for people. You can even go swimming there if you want, although it’s pretty hard to swim because all that salt makes it much easier to float! It’s really unbelievable.

Want to know more about it? Just explore it yourself!

【推荐2】There are many ways to help improve your health like eating healthy food, taking exercise and getting medical help. But the easiest and cheapest way to improve your health is just to sleep eight hours or more every night. The general sleeping rule is that the younger you are, the longer sleep you need. But regardless of age, some people need to sleep more while for some a few hours is enough.

The problem with sleep is that more and more people in the world are not sleeping enough. According to the World Health Organization, over half the people in the world may be sleep-deprived. People will feel tired even causes accidents when they don’t sleep enough time.

How do we teach these people to learn the value of sleep? Perhaps they may listen to the advice of Dr James Meens, who is an expert in sleep. He says, “Sleep is like a credit card. When you sleep less. You are only borrowing time. You always have to pay it back. The more hours you don’t sleep, the more hours you should sleep to pay back the hours on your sleep credit card.”

For those who value work more than sleep they should listen to what a famous person once said, “Don’t think you will be doing less work because you sleep during the night. That is a foolish idea which is held by people who have no imagination. You will be able to do more.”
