五、阅读理解
Protecting the earth is like protecting our eyes. People’s attention to recycling is increasing. From recycling plastic bags to using environment-friendly products, there are many developments to be seen in almost every corner of the world.
Sweden is a worldwide leader in recycling. They open world’s first mall for repaired and recycled goods. It’s called ReTuna, a two-story building in Eskilstuna, Sweden, about 70 miles west of Stockholm. The clever thing about this mall is its position. It’s right next to the city’s recycling center. So a stream of cars is already coming to drop off unwanted household things. This produces a supply of things for the shops. There are 14 special shops. When goods arrive, a team sorts everything into categories(类别). The mall only sells goods that are recycled or “upcycled”, meaning unwanted things broken down and reinvented as something new. By doing so, 50 new jobs were created in repair and retail(零售).
“You can come and just do sustainable shopping and Sweden loves it. And the world loves it,” said Anna Bergstrom, the manager of the ReTuna Mall. “I think it’s fun to find something that people have used, and we can use further,” said Cato Limas, a ReTuna customer(顾客). “If you look at the things they’re selling here, they’re almost new. So actually, why do you need to buy new things ”
These unwanted things found new homes. In 2018, the mall sold second-hand goods worth $1.3 million.
( )26.The Sweden’s first mall for repaired and recycled goods is .
ReTuna B. Eskilstuna C. Anna Bergstrom D. Stockholm
( )27.How many new jobs were created in repair and retail
A.14. B.50. C.70. D.60.
( )28.What does the underlined word “sustainable” in Paragraph 3 mean
A.Lucky B.Private. C.Environment-friendly . D.Interesting.
( )29.Who is Cato Limas
A.A manager. B.A customer. C.A driver. D.A doctor.
( )30.The passage mainly talks about .
A.shopping in Sweden B.making more money
C.the mall selling second-hand goods D.what measures were taken to prevent pollution
六、七选五
31. The answer for most people would be yes. But where does our rubbish go
It doesn’t just sit in the rubbish bin. Every day, workers come to take the rubbish from our rubbish bins. They put it into a big truck and carry it to landfills(垃圾填埋场). At the landfill, people sort(分类) the rubbish. They recycle some, burn some and bury(埋) some of it underground. 32. It means that less rubbish ends up in landfills. Landfills can also be bad for the environment.
So many Chinese cities encourage everyone to sort out their rubbish before throwing it away. Put the food in one bag. Put the plastic bottles in another. And throw them in the right rubbish bins. In this way, we can help save a lot of time, money and energy for all of society.
33. So they have higher recycling rates(比率).In Sweden, only 4 percent of household waste ends up in landfills every year. In Japan, people recycle nearly 50 percent of all rubbish.
There is still a lot to do when it comes to rubbish sorting in China. People in the country make about 300 million tons of rubbish every year. 34. The rest of it ends up in landfills. Most of it is unsorted. The good news is that many cities are trying different ways to make things better. Beijing will start a new program to improve rubbish sorting next year. If people sort out their rubbish, they’ll get WeChat bonus points. 35.
A.But they only recycle less than a quarter of the waste.
B.Did you throw anything away today
C.Most foreign countries do not have sorting systems.
D.The more rubbish gets recycled, the better.
E.Many foreign countries have good sorting systems.
F.Parents should educate kids to throw away less food.
G.They can exchange the bonus points for shopping cards!

Dear Sir/Madam,
I have lived in this town ever since I was born and I love this town very much.
I think that there are beautiful areas in this town, but there are also areas that aren’t attractive, like the rubbish disposal areas at the bottom of our apartment blocks. There is rubbish coming out of the bins, and flies, cockroaches and rats running all over the rubbish. It is unpleasant to look at, smelly, and it makes the environment very unhealthy.
The problem is that the rubbish collectors do not come often enough to collect the rubbish. The people living here may also be throwing away too much rubbish.
We could try to ask people to produce less rubbish. I suggest that rubbish collectors collect rubbish more often as well.
I believe that a better environment can be created in this town and we should all work together to achieve it.
Yours faithfully,
Wang Xi

A sample writing
Dear Mayor,
I’m glad to write this letter to you. I’d like to talk about the environment in our city.
Our city is not as beautiful as before. Environmental problems are becoming more and more serious. The river is dirtier. People are throwing litter into the river or in public places like parks. This is turning beautiful places into ugly ones. Factories are putting waste into the river and they burn coal, which also pollute the air with a lot of black smoke. And most of us ride in cars to school even if they live close to school. I think it is time to play a part in saving the earth.
First of all, we should let more people know the importance of environmental protection. We’re supposed to save water and energy in our daily life. Second,to cut down air pollution, we should ride a bike or walk to school instead of riding in cars. If it’s far, we can take the bus or subway. Third, we shouldn’t throw litter here and there. We should put it in the bins. As for waste pollution, we should never take wooden chopsticks or plastic forks when buying takeaway food. We can also use reusable bags instead of plastic bags. What’s more, the government should close down the factories that are putting waste into the river or giving out a lot of black smoke.
The earth is our home and we have the duty to take care of it for ourselves. So I hope that you can take my advice. Thank you.
