Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk has become a problem in outer space too.
According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.
Objects, like bits of old space rockets or satellites, move around the planet at very high speeds, so fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle (交通工具).
To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U. S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.
To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.
Many scientists are also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.
"The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers," says Marco Castronuovo, an Italian space researcher.
"The time to act is now. The longer we leave the problem, the bigger it will become," he says.

Body image—the way people feel about their looks — is a big problem for many young people today. According to a study, more than half the teenage girls in the USA think they should be on a diet (节食). 1.
But what's the cause? In the study, many blame (责备) the media (媒体). Turn on the TV and you'll probably see beautiful models, handsome actors and healthy and strong sports stars. Open a magazine or a newspaper, look through the Internet, and it's usually the same.
Many young people feel pressure to look like these "perfect" people. 2. In the USA, the average woman is 163 cm tall and weighs 64 kilos, but the average model is 180 cm tall and weighs 53 kilos.
When people don't match up to these standards, they may become less confident. 3. Students can lose so many confidence that they start to stop taking part in classroom activities at school.
4. In the UK, for example, women over 50 spend more money on cosmetics (化妆品) than any other age group. Older men spend a lot of money trying to avoid hair loss. Is there a solution to the problem? A 2016 study in the UK suggested that body image lessons should be provided in schools. Others believe it's a problem that all of society needs to deal with. 5.
A.But for most, this is just not possible.
B.Some stop eating properly in order to lose weight.
C.But most of the adults don’t pay attention to it at all.
D.Body image problems don’t disappear as we get older, either.
E.When we get older, maybe we more care about our health and safety.
F.They suggest we need to judge people by what they do, not what they look like.
G.And almost 20% teenage boys are worried about their bodies and weight.

Air pollution is a big problem for cities. Many people are dying from it. But how can we tell the air quality(质量) is good or bad?
Joris Lam has invented a birdhouse that can tell us about the air quality. On a tree next to a canal (运河) in Amsterdam, a small birdhouse will shine bright green when the air is clean. If you are standing near the birdhouse, it will also give you a free Wi-Fi connection. So Joris’s birdhouse is called TreeWifi. It can be put on a tree around your house to test the air quality. People can see a screen with information about local air quality and how to improve it. TreeWifi is a simple way for people to know about the air pollution around them. If the birdhouse doesn't shine, people will care more about the environment. It tells them to change their lifestyles. For example, to protect the air, they can ride bikes instead of driving cars.
Joris and his team are trying to make some changes to the birdhouse. In the future, the heat of its green light will be used to keep birds warm in winter.
1、2题完成句子;3题简略回答问题;4题找出并写下第二段的主题句;5题将文中画线句子译成汉语。
1.Many people die because of the ______.

Smog is a big problem in many Chinese cities. But it seems that besides wearing a mask (口罩), few of us know what has caused the smog and what to do to beat it. Chai Jing, former news anchor with Chinese Central Television, discussed the questions in her documentary Under the Dome (穹顶之下).
The 103-minute film was released on major Chinese video-sharing websites on Feb 28. In the film, Chai visits polluted places and talks to officials and scientists. She concludes that burning too much coal and oil are the main causes of PM2.5 and smog.
To make things worse, according to Chai, the coal and oil we are burning is of poor quality and doesn’t meet the standards (标准) for environmental protection. Therefore Chai says more harmful gas and particles (颗粒) have been produced to pollute the air. To solve the problem, Chai suggests that we should clean our coal and oil or replace(代替) them with cleaner energy such as natural gas.
In her film, Chai also suggested that we should do something to help control smog too. For example, she says we can live a greener life by using more public transportation. Or if we see things that harm the environment, we will try to stop it. In one scene from the film, Chai saw a dirt mound in a building site exposed in the air, she asked the person in charge to cover it. When she saw a restaurant cooking without any suitable filter facilities (过滤设备), she called the hotline 12369. The restaurant installed the filter a week later.
Chen Jining, the new minister of environmental protection, praised Chai. “This film encourages ordinary people to care for the environment. This is what we need in the future.”
