3.It is found in Africa, the Middle East, and Asia—in about 60 countries altogether. When desert locusts swarm, they bring problems to onetenth of all the humans in the world.

We have been used to wearing masks(口罩)in public since February. About 300 million masks are used and then thrown away every day in China. Where do these masks go? You might think they just go in a rubbish bin. But that's just the first stop on the masks' journey.
After the masks are thrown into the bins, rubbish trucks empty the bins and take the rubbish to landfills(垃圾场). Next, the masks will be taken to rubbish incinerators(焚化炉)and burned. Burning masks might not seem to be very good for the environment. Won't it cause pollution?
The answer is "no", according to China Daily. The main material of most masks is polypropylene(聚丙烯). It's non-toxic(无毒的). After burning, it changes into water and CO2.
In fact, burning the masks can bring some benefits(益处). The process of burning the rubbish can produce electricity. Burning one ton of rubbish can produce more than 400 kilowatt hours(度)of electricity. Some people make a prediction that there will be 162,000 tons of used masks in China this year. Burning all of them can produce more than 64 million kilowatt hours of electricity. This is enough to make an electric car drive about 370 million km, which is 9,250 times as long as the earth's equator.
At last, the slag(残渣)from burning masks can be recycled to make bricks(砖块)or fill the roads.
1.How many masks are used and then thrown away every day in China?

Maybe you should sit down before you read this. It's a little frightening. Your sitting may be killing you.
Health experts say the U.S. adult now sits about 6.5 hours a day. That is up about an hour a day compared to 2007. The news is even worse for teens. They sit eight hours each day. The information was put out by the National Center for Health Statistics. It has collected the numbers for the past 16 years. It is worried about what it has found.
Research shows that people who are not active can get sick. Their bones get weaker. They burn fewer calories (卡路里). That makes them more likely to put on too much weight. They might even get diabetes (糖尿病). They are at risk for high blood pressure and heart problems, too.

How to improve body and mind at home
To most people, holiday is a time to stay at home and have a good rest. Thanks to social media, computer games and online TV series and movies, staying inside is great fun. But too much time on media and digital entertainment could be a heavy burden to both the mind and eyes. Here are five activities you could try to get away from the screen for a while.
1.
If you choose a good book, it can help you enjoy a whole day at home. The ability of your brain to process words could be greatly improved through reading. And your vocabulary could be enlarged as well. Personally, paper copies are suggested. The touch and smell of real paper has no digital replacement.
2.
Everyone can write something, even if it may look very ugly at first. But the point of such practice is not to write beautiful characters. It’s about improving your ability to calm down and focus, as you must breathe deeply to keep your hands from shaking when practicing handwriting.
3.
You can just pick up a brush and draw anything, either nearby or something you imagine. Copying paintings is one nice beginning option. Copies of the Dunhuang Mogao grottoes are a good choice.
4.
Chopin, Mozart, Bach. Any of these great musicians could attract you with their works of art. Even if you prefer pop music, give classical music a chance.
5.
Many Chinese people, especially women, are crazy for yoga. Now it is a good time to practice yoga every day to relax your body. Likewise, you can try tai chi, which can improve both mind and body.
A.Read books, or at least listen to them.
B.Just listen, and let your brain and ears take a break.
C.You don’t have to be professional before picking up a brush.
D.While improving your mind, your body should also be cared for.
E.Drawing is natural pleasure that has a long history and it is still fun.
F.There are online audio lessons to help you learn a musical instrument.
