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 lovesit,” 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 .
A. 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!
