1 . Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that apart from comets (彗星) and stars, there is little else out there.
The first piece of space junk was created in the year of 1964, when the American satellite Vanguard I stopped operating.
The major problem with the space trash is that it may hit working satellites and damage travelling spaceship. In addition to this, many pieces of junk may crash with each other and break into pieces which fall back to the Earth.
| A．It lost its connection with the ground centre. |
| B．To avoid this, scientists have invented several ways for clearing the sky. |
| C．The junk floats slowly around the Earth. |
| D．However, since our space journey started, we have left much trash in space. |
| E．It is said that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. |
| F．Future plans include a cooperative effort among many nations. |
| G．It hasn’t resulted in any serious problems up to now. |
2 . A Plastic Ocean is a film to make you think.Think,and then act.We need to take action on our dependence on plastic.We’ve been producing plastic in huge quantities.Drinking bottles,shopping bags and even clothes are made with plastic.
The film begins as a journey to film the largest animal on the planet,the blue whale.But during the journey the filmmakers make the shocking discovery of a huge,thick layer of plastic floating in the Indian Ocean.

3 . The process by which rich land becomes desert is called desertification(沙漠化).
Africa’s Great Green Wall is a project to build an 8000-kilometer-long forest across 11 of the continent’s countries. The project is meant to contain the growing Sahara Desert and fight climate change.
Launched in 2007, the project aims to plant a forest from Senegal on the Atlantic Ocean in western Africa to Eritrea, Ethiopia and Djibouti in the east.
The U. N. desertification agency says the project will need to plant an average of 8. 2 million hectares yearly to reach its goal of 100 million hectares by 2030.

| E．The project would create millions of green jobs in rural Africa. |
| F．Despite many problems, those involved in the project remain hopeful. |
| G．Some countries have struggled to keep up with the demands of the project. |
4 . Floods can strike quickly and with little waning in many parts of the world. Surviving a flood is a matter of preparation and correct action as soon as the disaster begins.
●Make a flood survival plan.
●Escape flood waters.
You may have only a short time to escape. Act quickly, using your planned route. Head to the chosen shelters during flood warnings. When emergency services tell you to leave, follow their advice. Move to higher ground away from water. Whether you are on foot or have to give up your car, higher ground is your best option. If you’re stuck at home, head for the roof if you can do so safely.
Avoid crossing through water. Water up to your ankles (脚踝) is enough to be dangerous. When you’re not sure of the water depth, don’t risk it.
●Follow news and warnings.
Flooding information can be found on your local news or weather station’s TV channel or website.
●
Roads and other paths may have been destroyed. Stay off bridges. The soil under usual routes will be soft and less able to support the weight of vehicles. Find other routes over high ground or wait for the authorities to indicate which roads are safe.
| A．Watch out for damaged areas |
| B．Protect your home during a flood |
| C．If you have to go through water, bring a stick |
| D．Sit down with your family to establish a plan of action |
| E．If your car gets stuck in water, open or break the windows |
| F．Here are some tips to help you and your family survive a flood |
| G．You should receive weather information to monitor changes in the weather |

8 . Microplastics are “one of the greatest man-made disasters of our time”, according to the Natural History Museum. That’s bad news, given they are also everywhere: in tap water, the food you buy, the clothes you wear and the air you breathe.
The largest microplastics can be seen by the naked eye and are anything under half a cen- timetre in size. But many of them are small enough to act like spots of dust which we can unconsciously breathe in or eat in food. The smallest particles are called nanoplastics and they are small enough to get their way deep into the human body.
New findings from the University of Portsmouth show that there is so much synthetic material in our homes that we might be breathing in up to 7, 000 microplastic particles a day. Using special equipment, researchers measured a typical family home and found the highest concentration of it was in the bedroom of the eight-year-old daughter, whose room was decorated with plastic-based bedding, carpet and soft toys.
Although research is in its early stage, the risks of these plastics could be serious—some studies have linked high exposure to cancer risk and disrupting our hormones. In animal studies, the particles have been shown to affect metabolism, gut bacteria and the immune system, among other things.
It is not yet known what a healthy level of microplastics might look like, but Dr Sabine Donnai, CEO of the Viavi clinic, thinks that many people in the West are over the limit. In tests at her clinic, patients often come back with dangerously high levels of plastic in their bodies, she says.

| A．New study found microplastics | B．Microplastics are found in clothes |
| C．Microplastics are threatening our life | D．We breathe in microplastics every day |
9 . More and more birds are flying to settle at Qinghai Lake, one of the highest inland lakes in China, thanks to the protection efforts of local governments. Covering an area of over 4,000 square kilometers. Qinghai Lake is also the country's biggest saltwater lake. Located in Northwest China's Qinghai Province, the lake is famous for the two islands at its northwest point--Cormorant Island and Egg Island. The two islands have plenty of floating grass and various schools of fish, offering rich food sources for birds. The islands have become a paradise(天堂) for different kinds of groups of birds and have been called"Bird Islands".
Each March and April, when ice and snow covering the Qinghai-Tibet Plateau starts to melt, over 20 kinds of birds fly to the Bird Islands to lay eggs. During the months, flocks of birds cover the whole sky over the islands and birds eggs can be found everywhere. Visitors can hear the singing of birds from miles away. These have become a world famous symbol of the lake.
To protect this paradise for birds and support calls for ecological protection, China set up the Qinghai Lake Natural Protection Zone at the end of 1997. Meanwhile, the State has pointed out the Bird Islands and Spring bay of the Qinghai Lake as central protection zones.
Inspection(视察) officials and management employees often patrol（巡逻） the lake, improving local residents' knowledge of related laws and spreading knowledge about animal protection to visitors. They are making great efforts to call on people to love and protect the birds. At the same time, they have built special fences around the island area to prevent wolves, foxes and other carnivorous(食肉的) animals, as well as illegal hunters from breaking up the birds’nest building,egglaying and breeding. As a result, more and more birds are coming to the islands for sheltering and breeding.
