阅读下列短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
A
Deciduous forests （落叶林） are home to many wild animals. The development and expan-sion of human presence in the forests has caused many of their native species to become endan-gered.
Giant Panda
The giant panda， one of the most recognizable endangered species， is a large， docile species of bear native to the deciduous forest of eastern China， Myanmar and Vietnam. Because of its lim-ited diet— the panda’ s main source of food is bamboo— the species is limited in its habitat to areas where bamboo is available. Now the species only can be found today in 20 small patches of forest at the western edge of its historic range.
Gray and Red Wolves
The gray wolf， which once ranged from the East Coast of America to the West， and south to Mexico， now has a population of only 5， 000 in the lower 48 states， mostly in the Rocky Mountains. The smaller red wolf， native to the southeastern United States， was declared extinct in the wild in 1980， though conservation efforts have reintroduced small captive populations to the wild in California.
Red － Crowned Crane
The red － crowned crane is native to Japan， Korea and eastern China. Agricultural expansion and deforestation（森林砍伐） in these areas have removed a great deal of the marshes and forests that are the crane’ s primary habitats. For a time， the crane was thought to have completely disap-peared from Japan， but the recent discovery of cranes in Japanese marshlands has restarted con-servation efforts. Today， around 2， 500 cranes live
in the wild， including 1， 000 in Japan.
European Mink
Native to Europe， the European mink ranges from France in the west to Finland in the north，Russia in the east and the Balkans in the south. Destruction of the mink’ s aquatic （ 水 的 ） habi-tat and use of the species for fur have caused dramatic drops in the species’ population， which has been reduced by 85 percent since the mid －19th century.
1. What has caused the wild animals to become endangered？ A. Global warming.
B. International trade. D. The invasion of mankind.
C. Environmental pollution.
2. Which species is native to North America？ A. European Mink.
B. Red Wolves.
C. Red － Crowned Crane. D. Giant Panda.
3. Which is mentioned as the reason for the decline of European minks？ A. The loss of their natural food. C. Drought and forest fires.
B. The hunting of human beings. D. Excessive deforestation.
4. What is the purpose of the text？ A. To call for more efforts to protect forests. B. To study the living habits of wild animals. C. To introduce some endangered species. D. To find ways to protect wild animals.
B
No books， no whiteboards， no markers or pens. That’ s the new reality for many classrooms across Abu Dhabi， the capital city of the United Arab Emirates （ UAE） ， where a company is u-sing artificial intelligence （ AI） to create a new learning experience.
Built four years ago， Alef Education has managed to get its digital education platform into several schools in Abu Dhabi. Alef has worked closely with the government of UAE to bring the platform to 25， 000 students at 57 public schools.
The platform focuses on main subjects like math， science and English. It helps students by using AI to design curriculums for individuals.
It also gives students， teachers and parents real － time feedback. For students， that could mean a more personalized way to help them better understand what they are learning. The plat-form can also find students’
strengths.
“ If a student is doing really well at science， why not raise their interest in what it’ s like to be a scientist？ ” Alef Education CEO Geoffrey Alphonso said. “ That’ s our future goal to use AI to create individual learning plans. ” But there are concerns that using the technology could come at a cost， such as increasing the amount of time children spend in front of screens.
Alphonso said that his program solves this problem by limiting screen time to 3 hours and a half a day. The classes are followed by practical activities in which children interact with one an-other and use their hands for experiments.
“ We are looking to grow in countries that have a need for changing their education system，”Alphonso said， adding that the company plans to bring its platform to more than 300 schools this year. 5. What is the benefit of the platform？ A. Lightening teachers’ burden. C. Creating a new learning style.
B. Improving teaching efficiency. D. Inspiring students to work harder.
6. How does Alef respond to the concern about the platform？ A. Limiting children’ s screen time. C. Organizing sports activities.
B. Decreasing the operating cost. D. Providing real － time feedback.
7. What is Alef Education’ s future plan？ A. To update their digital platform.
B. To change UAE’ s education system. D. To build 300 schools in Abu Dhabi.
C
“ The moment before they called my name， I was really nervous because the other finalists’presentations are really good and I thought they would win， ” Kara Fan， 14， who has won Ameri-ca’ s Top Young Scientist， told Yahoo Finance. “ When they announced my name， I was really surprised actually. ”
To win that claim， Fan’ s nano － particle liquid bandage had to surpass the experiments of hundreds of fifth to eighth graders as well as nine other finalists. Fan started developing her liquid bandage in April 2019 to fight the overuse of antibiotics（抗生素）.
According to the CDC， roughly 2 million people every year suffer a bacterial infection in the U. S. and about 23， 000 passed away as a result. If left alone， a UN study reported， drug － resist-ant diseases or the “ superbug” could lead to 10 million deaths across the globe by 2050. When Fan’ s sprayable bandage dries on a person’ s skin， it creates a thin layer that protects the woun-ded area while breaking the cell wall and killing the bacteria on the skin. After experimenting with copper nitrate（硝酸铜） to fight bacteria， switching to the silver
C. To expand business to other countries.
nitrate ended up being the major catalyst （催化剂） to seeing results for her award － winning project.
“ Thousands of years ago， ancient people would use copper and silver to eat with and they would drink water from like copper bowls to kill bacteria， ” Fan explained. “ I found out that it didn’ t work. So I used nano silver. ”
Sir Alexander Fleming’ s discovery of penicillin— a type of antibiotic— is Fan’ s favorite sci-entific discovery. That said， she doesn’ t think humans should rely too heavily on penicillin.
Following her years at Westview High School， Fan hopes to continue her biology track at Stanford University. Along with the ＄ 25， 000 cash prize she won on October 29， becoming Amer-ica’ s Top Young Scientist may help get the private university’ s attention.
8. How did Kara Fan feel about her winning the prize？ A. Confident.
B. Regretful.
C. Proud.
D. Unexpected.
9. For what purpose did Fan develop her liquid bandage？ A. To fight overuse of antibiotics. C. To reduce deaths from injuries.
B. To enter a national contest. D. To get into a good university.
10. Which of the following does Fan use to kill bacteria？ A. Copper nitrate.
B. Copper.
C. Silver.
D. Nano silver.
11. What might be Fan’ s opinion about penicillin？ A. Addictive.
B. Valuable.
C. Useless.
D
Rainbow － coloured rubbish is the colourful waste created by a Swedish city with a unique re-cycling system. Like many cities in Sweden， Eskilstuna has an impressive recycling record. It met the EU’ s 2020 target of recycling 50％ of waste many years ago. But almost everyone who lives here follows a strict recycling policy at home. People are expected to sort their household waste into seven separate categories， including food， textiles， cartons and metal. But what really makes the system stand out is the bright colour code.
The reason for this becomes clear at the city’ s recycling plant. The bags arrive all jumbled up because they’ re collected altogether， once a fortnight from outside people’ s houses. But thanks to those bright colours， scanners can select the bags and separate them efficiently. The food waste in green bags is processed on site into slurry（浆） to make biogas， which powers the city’ s buses. One of the benefits of this method of recycling is that there is less cross － pollution，so more of the recycled waste can actually be used to make new things.
Like the rest of Sweden， Eskilstuna is committed to sending zero waste from its citizens to landfill（垃圾堆） . Waste that cannot be recycled is incinerated at a local plant to generate elec-tricity. This reduces reliance on fossil
D. Irreplaceable.
fuels， but does create greenhouse gases. As countries a-round the world try to improve their recycling rates， some may look to Eskilstuna as an example to follow— as long as they think they can persuade their citizens to get busy sorting at home.
12. How do people deal with their household waste in Eskilstuna？ A. Sorting and putting it in colourful bags. B. Dyeing it with different colours. C. Processing and recycling it at home. D. Sorting and taking it out every week.
13. What is the advantage of the bright colour code？ A. It avoids cross － pollution entirely. B. The waste can be stored in a fixed site. C. It’ s easier to classify the bags of rubbish. D. The city takes on a colorful look.
14. What does the underlined word “ incinerated” mean in the last paragraph？ A. burnt
B. broken
C. reused
D. washed
15. Which of the following is the best title of the text？ A. Tips on Sorting of Household Waste. B. A Swedish City’ s Recycling Efforts. C. A Unique Waste Recycling Plan. D. A New Policy for Conservation.
