Social distancing is not a new concept in the natural world, where infectious diseases are commonplace. Through specialized senses animals can detect certain diseases and change their behavior to avoid getting ill.
In 1966, while studying chimps (猩猩) in a Tanzanian national park, zoologist Jane Goodall observed a chimp named McGregor who had caught a highly infectious virus. His fellow chimps attacked him and threw him out of the troop. In one instance, McGregor approached chimps in a tree. He reached out a hand in greeting, but the others moved away without a backward glance.
“For a full two minutes, old McGregor sat motionless, staring after them,” Goodall notes in her 1971 book In the Shadow of Man. “It’s really not that different to how some societies react today to such a tragedy.”
Not all animals are so aggressive toward their ailing neighbors. Sometimes it’s as simple as avoiding those who may infect you.
When Kiesecker, a lead scientist in America, studied American bullfrog in the late 1990s, he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs, but healthy members actively avoided those that were sick. Bullfrogs rely on chemicals signals to determine who is sick or not.
Caribbean lobsters also shun diseased members of their community, well before they become infectious. It takes about eight weeks for lobsters infected with the deadly virus Panulirus argus mininuceovirus to become dangerous to others. Normally social animals, lobsters begin keeping away from the diseased as early as four weeks after infection – once the lobsters can smell certain chemicals released by sick individuals.
Overall, it’s important to note that, unlike us, animals don’t realize if they stay home, they might actually reduce the infection rate,” Kiesecker explains. “As humans, we have that ability. It’s a big difference.”
What can we learn about the chimps from Goodall’s observation
A. They kept a distance from one another.
B. They became aggressive when infected.
C. The infected avoided contact with others.
D. The infected were forced to leave the group.
2. What does the underlined word “shun” in Paragraph 6 probably mean
A. Avoid. B. Cure. C. Get rid of. D. Get along with.
3. How are humans different from animals according to Kiesecker
A. Humans are more sensitive to virus.
B. Humans are less likely to get infected.
C. Humans treat infectious diseases in a wiser way.
D. Humans can detect chemical signals more quickly.
4. Which might be the best title for the text
A. Help Me Out B. Leave Me Alone
C. Stay Away From Us D. Stay Home Stay Healthy

Home appliances and consumer electronics products witnessed strong sales during the Spring Festival holiday, as stay-at-home consumers purchased cutting-edge (尖端的) digital products to keep themselves entertained and to send wishes to family members in other cities. According to the Ministry of Commerce, sales of communication equipment and home appliances rose by 39 percent and 29. 9 percent during the seven-day holiday.
Ma Ke, a white-collar worker in Beijing, did not go back to her hometown in Wuhan, Hubei Province during the holiday. Instead, she bought a 5G smartphone and a smartwatch for her parents as New Year gifts. “My father is a fan of electronic products. He always wants to be an early user of the latest phones and smartwatches,” Ma said. Consumers like Ma are answering the local measures to stay where they work during the holiday period in a bid to reduce the potential spread of the COVID-19 (新型冠状病毒). While staying put, they are buying the latest digital products and adopting cutting-edge digital technologies. Some of them have bought new fitness device, as the stay-at-home-fitness trend is booming in China.
Sensing many consumers have not traveled during the holidays, shopping malls have also come up with new ideas to better entertain them. Shopping malls in Shenzhen and Beijing, for instance, have set robots powered by artificial intelligence (AI) to issue a variety of coupons (优惠券) for dining, movies, sports and other activities to attract consumers.
Jacky Han, vice-president of marketing at tech company Cheetah Mobile, said shopping malls play a central yet complicated role in the retail ecosystem. “AI-powered robots can help merchants to convert foot traffic into intelligent data, by functioning as an interactive advertising platform and information desk and transforming the customer experiences,” Han said.
5. Why did people buy advanced digital products according to paragraph 1
A. To keep up with fashion trends. B. To entertain themselves and contact their families.
C. To help strengthen Chinese economy. D. To give them to their friends as presents.
6. What can we learn from paragraph 2

B. It is difficult for the elders to adapt to the digital age.
C. Office workers are primary consumers of fitness equipment.
D. Staying put may promote the consumption of electronics.
7. How did shopping malls attract consumers during the holiday
A. By using robots to send out coupons. B. By letting kids experience AI technology.
C. By offering a free parking service. D. By providing various entertainments.

阅读A篇：1-4 DACC
本文是说明文，动物和人类一样，在有传染疾病时和同类保持距离，但是人类的应对方法更明智。
1．推理判断题。根据第二段“His fellow chimps attacked him and threw him out of the troop.” 他的猩猩同伴袭击了他，把他赶出了猩猩群。可知受到感染的猩猩被迫离开了群体，故选D项。
2．词义猜测题。根据前一段“he found that bullfrogs could not only detect a deadly smell of infection in other bullfrogs, but healthy members actively avoided those that were sick.” （他发现，牛蛙不仅能嗅出其他牛蛙身上致命的感染气味，而且健康的牛蛙还会积极地避开那些生病的牛蛙)。划线部分所在的句子“Caribbean lobsters also shun diseased members of their community,”出现了also，可知加勒比海的龙虾也像牛蛙一样避开得病的成员，故shun和avoid同义。故选A项。
3．推理判断题。根据最后一段“it’s important to note that, unlike us, animals don’t realize if they stay home, they might actually reduce the infection rate,” Kiesecker explains. “As humans, we have that ability. It’s a big difference” (值得注意的是，动物不像我们，它们没有意识到如果它们呆在家里，它们实际上可能会降低感染率，”Kiesecker解释道。“作为人类，我们有这种能力。这是一个很大的区别。)可知，从Kiesecker说的话可推断，人类和动物的不同之处在于人类对待传染病的方法更明智。故选C项。
4．主旨大意题。根据第一段“Social distancing is not a new concept in the natural world, where infectious diseases are commonplace.” (在传染病司空见惯的自然世界中，保持社交距离并不是一个新概念。)以及文章第一段提到了关键词Social distancing(保持社交距离)，即离我们远一点，故C项“远离我们”为最佳标题。故选C项。
B篇：5-8 BDAD
本文是说明文。这是一篇说明文。文章讲述了假日期间，电子产品销售火爆。
细节理解题。根据文章第一段“to keep themselves entertained and to send wishes to family members in other cities.（为了让自己娱乐，并向在其他城市的家人送去祝福）”可知，人们买电子产品是为了娱乐和与其他城市的家人联系。故选B。
细节理解题。根据文章第二段“While staying put, they are buying the latest digital products and adopting cutting-edge digital technologies. Some of them have bought new fitness device, as the stay-at-home-fitness trend is booming in China.（在原地不动的同时，他们购买最新的数字产品，采用尖端的数字技术。他们中的一些人购买了新的健身器材，因为在家健身的趋势正在中国蓬勃发展）”可知，stay put可能促进了电子产品的消费。故选D。
细节理解题。根据文章第三段“Shopping malls in Shenzhen and Beijing, for instance, have set robots powered by artificial intelligence（AI）to issue a variety of coupons (优惠券)for dining, movies, sports and other activities to attract consumers.（例如，深圳和北京的购物中心设置了由人工智能(AI)驱动的机器人，为餐饮、电影、体育和其他活动发放各种优惠券，以吸引消费者）”可知，购物中心通过使用机器人发送优惠券来吸引消费者。故选A。
主旨大意题。根据文章第一段“Home appliances and consumer electronics products witnessed strong sales during the Spring Festival holiday, as stay-at-home consumers purchased cutting-edge (尖端的) digital products to keep themselves entertained and to send wishes to family members in other cities.（家用电器和消费类电子产品在春节期间销售强劲，因为在家的消费者购买尖端的数字产品来娱乐自己，并向在其他城市的家人送去祝福）”可知，新冠假日期间，电子产品销售火爆。故“假期电子产品销售火爆”可以作为本文最佳标题。故选D。
