DID YOUR FAMILY moved before How did you adjust to life in a new place Nowadays, scientists helped some Burrowing Owls settle (安置) into their new homes.
Burrowing owls are small brown long-legged birds. They make homes in underground burrows (洞穴) and prefer to live in groups. In California, U.S.A．, there is another kind of owls called the Western Burrowing Owl.
In the past, these owls lived in the grasslands. Later, people began building cities on many of the grasslands. This drove the owls off their burrows. Some of these birds were unable to find new homes. As a result, the number of Western Burrowing Owls in California was fewer than that in 1965. If the number keeps falling, they will be at risk of dying out.
Luckily, scientists found out the problem some years ago. They soon began trying to move these owls to some protected grasslands. In order to make the birds feel more “at home”, scientists played the recording sound of owl calls in these areas. They also used white paint to make fake droppings (假粪便) of the owls. This made the birds believe that other owls were living there. As a result, they accepted (接受) their new home and stayed there.
Scientists returned to check on the owls. Most of them seemed to like their new homes. Good luck to them enjoying their new lives there!
26．What can we know about Burrowing Owls according to Paragraph 2
A．They like living in groups. B．They only stay in California.
C．They make homes in the trees. D．They have small black legs.
27．Which of the following is TRUE according to Paragraph 3
A．Burrowing Owls moved into new homes.
B．The number of Burrowing Owls fell down.
C．Burrowing Owls found new homes in cities.
D．Burrowing Owls had no places to live in 1965.
28．What does the underlined word “This” refer to
A．Playing the recording. B．Painting owls white.
C．Making fake droppings. D．Recording the sound of owl.
29．What’s the best title of this article
A．Burrowing Owls B．People and Nature
C．Burrowing Owls’ New Home D．Burrowing Owls and Scientists
30．According to the article, we can infer (推断) ________.
A．people won’t build their cities on the grassland
B．scientists won’t find ways to protect these owls
C．Burrowing Owls will die out in the near future
D．more Burrowing Owls will live in new homes
【答案】26．A 27．B 28．C 29．C 30．D
【导语】本文介绍了科学家们在草原播放猫头鹰的叫声，以及制作假粪便，让穴居猫头鹰介绍它们的“新家”并住在这里。
26．细节理解题。根据“They make homes in underground burrows (洞穴) and prefer to live in groups.”可知，它们喜欢群居。故选A。
27．细节理解题。根据“As a result, the number of Western Burrowing Owls in California was fewer than that in 1965.”可知，结果，加州西部穴居猫头鹰的数量比1965年要少，即穴居猫头鹰的数量下降了。故选B。
28．词句猜测题。根据“They also used white paint to make fake droppings (假粪便) of the owls. This made the birds believe that other owls were living there.”可知，他们用白色油漆制作猫头鹰的假粪便，这让鸟儿们相信那里住着其他猫头鹰。“This”指“制作假粪便”。故选C。
29．最佳标题题。通读全文可知，本文介绍了科学家们在草原播放猫头鹰的叫声，以及制作假粪便，让穴居猫头鹰介绍它们的“新家”并住在这里。选项C“穴居猫头鹰的新家”符合文意。故选C。
30．推理判断题。根据“Most of them seemed to like their new homes. Good luck to them enjoying their new lives there!”可知，大多数穴居猫头鹰喜欢它们的新家，由此推知更多的穴居猫头鹰将住进新家。故选D。

Most polar bears (北极熊) could disappear by the end of the century because of global warming, scientists say.
According to a study in Nature Climate (气候) Change, the number of most polar bears will 11 rapidly (快速地) by 2080. There are two reasons. One is that the sea ice is melting (融化). Polar bears catch seals (海豹) to eat on the ice. 12 ice, they have to stay on land. But there is no 13 food on land to support so many polar bears. The animals could die from hunger. The other reason is that mother bears may not be fat enough to 14 milk for their babies, so some bears could stop having babies.
Polar bears are 15 land animals that eat meat on the planet. They help control other kinds of animals. Losing them would break the balance of their living place.
The Arctic is the 16 to about 25,000 polar bears. Arctic sea ice usually melts in spring and summer, then grows in winter. But now, the 17 is taking longer to grow back. Scientists say the Arctic is warming twice as fast as the rest of the planet.
The study also shows 18 it is possible to slow Arctic melting. Greenhouse gases (温室气体) could lead to climate change. In order to avoid creating greenhouse gases, the world should try to stop burning coal and riding in cars.
Saving the bears is 19 us. Holland, one of the writers of the study, says, “I believe there is hope, but humans need to act 20 to make that hope come true.” Let’s take action to protect our earth and save polar bears.

DID YOUR FAMILY moved before How did you adjust to life in a new place Nowadays, scientists helped some Burrowing Owls settle (安置) into their new homes.
Burrowing owls are small brown long-legged birds. They make homes in underground burrows (洞穴) and prefer to live in groups. In California, U.S.A．, there is another kind of owls called the Western Burrowing Owl.
In the past, these owls lived in the grasslands. Later, people began building cities on many of the grasslands. This drove the owls off their burrows. Some of these birds were unable to find new homes. As a result, the number of Western Burrowing Owls in California was fewer than that in 1965. If the number keeps falling, they will be at risk of dying out.
Luckily, scientists found out the problem some years ago. They soon began trying to move these owls to some protected grasslands. In order to make the birds feel more “at home”, scientists played the recording sound of owl calls in these areas. They also used white paint to make fake droppings (假粪便) of the owls. This made the birds believe that other owls were living there. As a result, they accepted (接受) their new home and stayed there.
Scientists returned to check on the owls. Most of them seemed to like their new homes. Good luck to them enjoying their new lives there!
