The heating of Earth is pushing the number of polar bears to get smaller and smaller. According to a new study, they could die out in fewer than 100 years.
Polar bears are animals which live by eating sea seals in the Arctic ocean. As more and more sea ice melts(融化), their living places become to shrink. The loss(丧失) of sea ice began to be paid more attention at the end of the 1970s. Since then, sea ice that lasts for more than a year in the Arctic has decreased at a rate of 13% per decade(十年).
Studies have long shown that the growing loss of sea ice will lead to a dangerous situation for polar bears, but the new research shown in Nature Climate(气候) Change has given us a clear dying out timeline. Polar bears will be unable to live because of the climate change over the next several decades. The scientists believe they will completely die out by 2100.
"What we're found out is that, first, it will be very difficult for cubs(幼崽) to be born and live. Even if cubs are born, the mother polar bears won't have enough body fat(脂肪) to produce milk to bring them along through the ice-free season," said Dr. Steven Amstrup, a scientist of Polar Bears International, to the BBC. "Any of us knows that we can't go without food for a long time. That's a natural need for all humans and animals."
The research also shows that, even in a situation where many countries have done a lot of work to save polar bears, several populations(族群) of polar bears will die out. But Amstrup strongly believes that the animals can still do whatever they can do to live if the climate change does not go on getting worse.
"We must show how dangerous the situation is, because we have to do something now to stop the worst of future problems," he said. "The way we're on now is not good enough, but if society can do something together, we will have time to save polar bears. And if we do, we will do great good to other lives on Earth, and to ourselves too."
( )4. The underlined word "shrink" in Paragraph 2 probably means " ".
A. get bigger B. get lighter C. get smaller D. get heavier
( )5. According to the passage, polar bears will probably die out because .
A. sea seals in the Arctic Ocean don't have enough body fat
B. sea ice becomes less because of the climate change
C. the new research has given a dying out timeline
D. fewer animal scientists pay attention to them
( )6. What is Paragraph 4 mainly about
A. Why cubs are hard to be burn and live in ice-free season.
B. Why humans and animals can't live through without food.
C. Why mother polar bears can't produce enough milk for cubs.
D. Why Dr. Steven Amstrup does the research about polar bears.
( )7. What is Dr. Steven Amstrup's opinion(观点) on what many countries have done
A. What they have done works well, so polar bears will not die out.
B. What they have done doesn't do any good, so they need to change.
C. What they have done is useful but not enough, so they need to do more.
D. What they have done makes things worse, so polar bears will die out soon.

六、阅读文章并回答问题，每题答案不超过6个词。
In recent years, plastic pollution has become one of the most serious environmental problems around the world. Many countries have been looking for ways for a better future. On November 7, 2022, China started a “bamboo instead of plastic” activity with the International Network for Bamboo and Rattan (INBAR国际竹藤组织). This will hopefully increase the use of green bamboo products and reduce plastic pollution.
Bamboo is a renewable natural resource of great value. Unlike trees which usually need so long time to fully grow, bamboo can be harvested in 3 to 5 years. As long as it is protected well, bamboo can be cut every year and doesn’t have to be replanted. Bamboo can be used to produce different kinds of products. These products can take the place of plastic products in many fields, such as packaging(包装), building and daily things. Even a new bamboo washing machine has been invented in some poor areas where people don’t have electricity or money to buy traditional washing machines. It uses the natural flow of the water as power to run the machine. It’s believed that bamboo is a harmless material. It doesn’t cause any pollution when it has to be thrown away.
China is one of the countries with the richest bamboo resources in the world. The Chinese are a pioneer in the use of bamboo. Provinces Zhejiang, Jiangxi, Hunan and Guizhou have set up companies to produce and develop bamboo products. What’s more, China is sharing its technologies and experience to help other countries with rich bamboo resources as well. It is hoped that countries will work together for green development around the world.
1.When did China start the “bamboo instead of plastic” activity
____________________________________________________________
2.What does the new bamboo washing machine use as power to run itself
____________________________________________________________
3.How many provinces have set up companies to produce and develop bamboo products
____________________________________________________________
4.How does China help other countries with rich bamboo resources
____________________________________________________________
5.What do you think of the “bamboo instead of plastic” activity
____________________________________________________________
七、根据首字母提示补全单词。
Garbage sorting(垃圾分类)began on July 1, 2019. However, I, with the other 238 families who live in my building, have been living with a similar system for years. Here, I’d like to talk about some of our e 1 .
In October 2016, our neighborhood was c 2 to be part of a pilot (试点的) program for garbage sorting by the government. To help the program run well, we set u 3 a volunteer team. I am one of the volunteers. Several of us, however, questioned if we could lead people in the building to change their habits.
We began with the usual ways. We h 4 out notices around the neighborhood. We also went door to door to tell people how to sort garbage. However, they made many m 5 . For example, many didn't know wet rubbish meant food waste. Instead, they thought it meant rubbish that was wet. Some even refused to sort their garbage.
As a r 6 , we volunteers had to do lots of sorting ourselves. At the same time we went around explaining the rules. We kept talking to those who refused to sort their garbage. We let them know we had sorted their garbage for them. It was a matter of time and patience. We believed they would f 7 change their mind.
Six months later, we were s 8 in changing people's mind. People in my building began sorting their garbage. Some even j 9 us to help us.
I think face-to-face talks played an i 10 part. They were much more useful than handing out notices. It was interesting to see what happened. I hope everyone knows garbage sorting is good for them.
