1 . In order to reduce the risk of suffering from COVID-19, people are supposed to say no to a handshake, give up high fives, refuse kisses on the cheek and absolutely avoid hugging. So people all over the world are changing their daily habits at work and at home to prevent it from spreading.
In France, handshaking is regarded as daily greeting habits. And kissing on the cheek is often seen even between people who have only just met. Philippe Lichtfus, a lifestyle expert notes that handshaking is a relatively recent development in human history that began in the Middle Ages. Now, he says simply looking into a person’s eyes can serve as a greeting.
The Brazilian health ministry has recommended that citizens should not share the metal straws traditionally used to consume the caffeine-rich drink chimarrão. And a kiss—even if it is not on the mouth—is totally advised against.
One of Spain’s most treasured traditions is also affected by the outbreak—the kissing of sculptures of Virgin Mary in the week leading up to Easter. During the holy week, the faithful believers queue up to kiss the hands or feet of sculptures of Mary and the saints, seeking their protection.
Germany’s interior minister (内政部长) Horst Seehofer rebuffed Chancellor（总理）Angela Merkel’s attempt to shake hands with him, smiling and keeping both his hands to himself. They both laughed and Merkel threw her hand up in the air before taking a seat.
In Iran, a video has gone viral (走红) showing three friends meeting, hands in their pockets, two of whom are wearing masks, tapping their feet against each other as a greeting. A similar video in Lebanon shows singer Ragheb Alama and comedian Michel Abou Sleiman tapping their feet against each other while making kissing noises with their mouths.
The UAE (阿拉伯联合酋长国) is advising citizens to stop the traditional “nose to nose” greeting. The UAE also said that people shouldn’t shake hands anymore or kiss. Greet each other “by waving only”.

2 . A sleepover (过夜) program, which is designed to make kids believe that their favorite toys enjoy reading, can help encourage children to pick up more books, a new study suggests.
Toys sleepover programs are designed to get children interested in books. Children take their toys to a library for the night. At this point, workers and volunteers take photos of the toys which explore the library and read books. The next day, the children collect their toys and the photos of what the toys did during the night. They are given the books their toys chose to read.
It was found that before the sleepover the children did not spend time looking at the books in their play area at preschool. Immediately after the sleepover, the number of children who read to the toys was higher than the number who did not, but after three days the effect decreased gradually.
The researchers also tested a method for sustaining the effect. They reminded the children of the sleepover a month later, by hiding the toys and showing them the photos again the next day. This simple method brought an increase in the number of children reading to their toys.
The study proves for the first time that children who take part in sleepover programs read picture books to their toys more. “We wanted to know if there really was an effect, and if so, how long it lasts. Surprisingly, not only did the children show interest in the books, but they also began to read to their toys. This means that a new behavior pattern appeared that the children hadn’t had before. We did not expect anything like this,” said one of the researchers.
Reading is important for the development of children’s language skills and imagination. When parents read to their children, it is a passive way of reading for the child. However, when children read to their toys, it is a more active, self-directed way of reading, helping them develop into more active readers, researchers said.

3 . The populations of common animals are just as likely to rise or fall in number in a time of accelerating global warming as those of rare species, a study suggests.
Until recently, scientists were still accumulating data on how animal populations were shifting over time globally across the different regions of the planet.
Making use of the newly available data, a team of University of Edinburgh researchers studied nearly 10000 animal populations recorded in the Living Planet Database between 1970 and 2014 to provide a new perspective on animal population change. These include records of mammals, reptiles, sharks, fish, birds and amphibians.
The team found that 15 percent of all populations declined during the period, while 18 percent increased and 67 percent showed no significant change. Amphibians were the only group in which population sizes declined, while birds, mammals and reptiles experienced increases. The overall decline in amphibians makes them a priority for conservation efforts, researchers say, as their loss could have knock-on effects in food chains and wider ecosystems.
Gergana Daskalova, of the University of Edinburgh’s School of GeoSciences, who led the study, said, “We often assume that declines in animal numbers are prevalent everywhere. But we found that there are also many species which have increased over the last half of a century, such as those which do well in human-transformed landscapes or those which are the focus of conservation actions.”
Dr. Isla Myers-Smith, also of the School of GeoSciences, who co-authored the study, said, “Only as we bring together data from around the world, can we begin to really understand how global change is influencing the biodiversity of our planet.”

4 . Killer whales, or orcas, are known for their severe attacks on sea animals but they have never posed a threat to humans. However, since late July, the normally social animals have been intentionally attacking sailboats off the coasts of Spain and Portugal.
The strange behavior first surfaced on July 29, 2020, when a 46-foot boat was repeatedly attacked for almost an hour by nine orcas, causing the boat to rotate(旋转) 180 degrees and having its engine switched off. Since then, over 30 more similar incidents have been reported. On September 23, 2020, Spain's government banned boats of less than 50 feet in length from sailing in the 60-mile stretch of the Atlantic coastline between Ferrol and the Estaca de Bares Cape, where the attacks have been occurring.
Researchers across the world are trying to explain the orcas' behavior. Some believe it could be a result of the overfishing of the bluefish tuna - the orcas' primary food source -which has left the area's killer whales starving and unable to feed their babies. "I saw them look at boats carrying fish. I think they know humans are somehow related to food shortages, "says Ken Balcomb, senior scientist at the Center for Whale Research in Washington, USA. The environmentalists believe the sudden increase in boat traffic and fishing activities, after months of absence due to restrictions on human activity last spring, could also be contributing to the agitation.
However, Alfredo López, a biology professor in Galicia, Spain, thinks the attacks are defensive measures the orcas adopted to protect themselves against boat injuries. The researcher came to this conclusion after looking at the of the videos of a few incidents and noticing that two of the young killer whales involved had serious injuries. Hopefully, the experts will be able to find a way to restore the harmony between the animals and the humans soon.

5 . Beijing resident Hou Lixin started eating meal replacement products in February when she wanted to lose weight. She bought various meal replacement products online and ate them for more than a month.
“Most of them don’t taste good, but at least they have low calories and are convenient to buy, store and cook,” she said, adding the product she consumed gave a strong sense of fullness.
Hou is by no means alone. Meal replacement products, or substitutes for regular meals that can fill you up with low-calorie intakes, appear as a potential big market in China, driven by Chinese consumer’ demand for products that can help in weight control and offer convenience, experts said.
The most common meal replacement products include powders, liquids, shakes, porridges and energy bars containing fiber, protein, vitamin, minerals and other nutritious content.
The meal replacement market is at the early stage of competition and there is big room for future development, like in the United States and Japan. Euromonitor International, a market research company, said sales revenue of meal replacement products in China hit 57.17 billion yuan in 2017 and is expected to reach 120 billion yuan by 2022. More fast-moving consumer goods giants are partaking in the market action. PepsiCo’s oat brand Quaker released a new shake product in June. A major Chinese snack brand Bestore released 27 meal replacement products in August.
Jia Jianbin, secretary general at Chinese Cereals and Oils Association, told CCTV reporter that despite its possible effectiveness that many people believe, this way of weight loss may bring greater harm as it breaks the balance of nutrition and food. As a result, it can only be a temporary move, not a long-term use.
“Cereal meal replacement powder, for example, is mainly composed of carbohydrates (碳水化合物), which have enough calories，but the vitamins and minerals are not enough. Instead, it is better to soak oatmeal (燕麦片) in milk, which may be more nutritious and more economical,” said Gu Zhongyi, a dietitian of the Beijing Dietetic Association. “Meal replacements can be an alternative for busy workers, but they are no substitute for a balanced diet, and try not to eat more than one meal a day.”
1. The author quotes the example of Hou Lixin to _________.| A．show an efficient way to lose weight |

| C．introduce the topic of meal replacement products |
| D．arouse readers’ interest in the meal replacement products |
| A．Because they are highly recommended by health experts. |
| B．Because they are helpful to control weight and bring convenience. |
| C．Because they have a large market share in the food market. |
| D．Because they provide various forms and flavors for the consumers. |
| A．Participating. | B．Advertising. |

6 . There is more that comes with older age than greying hair and wrinkled skin When humans reach their later years, they favour more established friends and their social circle is reduced.
Now, for what appears to be the first time, scientists have seen the same behaviour in another species. Twenty years of observations of chimpanzees (猩猩) reveal that older males choose to hang out with their long-term friends at the expense of other relationships.
The researchers studied 78, 000 hours of observations made between 1996 and 2016 that followed the social interactions of 21 male chimpanzees between the ages of 15 and 58 years old. They classified the chimps’ relationships depending on the amount of time they sat with others and groomed (梳毛) them. They then rated the various pairings as mutual (相互的) friendships, where both chimps seemed to enjoy the relationship; one-sided friendships, where one chimp was more keen to be friends than the other; and non-friendships, where neither chimp showed interest in the other.
When the scientists looked at the patterns of friendships, they found that the older chimps had more mutual friendships and fewer one-sided friendships than younger chimps. Another feature seen in older humans was also spotted in the chimps. As the males got older, their levels of aggression (挑衅) tailed off, meaning they started fewer fights and tended to intimidate others in their group less often.
The observations have left the researchers puzzled. According to an idea in psychology known as socioemotional selectivity theory, or SST, older humans prefer more positive relationships because they are aware time is running out. But many animal experts argue that chimpanzees lack the human sense of mortality (死亡), suggesting something else is driving the behaviour.
Robin Dunbar, a professor of evolutionary psychology at the University of Oxford, said in humans, the decline in social circles with age is due to declining social motivation to get out and meet people combined by lack of opportunity. In chimpanzees, as older males compete less for mates, they may focus on close, reciprocal (互惠的) relationships with trusted partners, she said.
1. What do older male chimpanzees favour?| A．Old friendships. | B．New bonds. |
| C．Greying hair. | D．Wrinkled skin. |
| A．By turning to other scientists. |
| B．By introducing a new concept. |

| A．Threaten. | B．Motivate. | C．Defend. | D．Accompany. |
| A．Awareness of time. | B．Less competition for mates. |

7 . That morning, I dropped our eldest at kindergarten and returned home to let our two younger children play while I worked on my medical report. It was a wonderful chance to work from home, but it hit me that my career in hospital wasn't making a difference in anyone's life. I needed something that would stretch my limits and push me to grow. My career enabled me to work from home. I could work from home, and become a foster mother, providing safety for a child who needed it desperately.
On Monday morning. I picked up the phone and dialed the number I had Googled for the nearest Department of Children's Services. The man on the other end was receptive to my questions and explained the next step of training, involving eight weeks of classes designed to prepare and educate foster parents. We continued through all the classes, the home visits, background checks, and seemingly endless steps.
Five long months after we were approved, the phone rang. In the middle of the night, I woke my husband and rushed to East Tennessee Children's Hospital. Our placement was waiting for us in the emergency room, sick and lack of nutrition. It didn't take long for us to realize the full depth of her suffering. Six months later, her half-brother came to us by our request. We now had five children under our care.
On August 12, 2016, our family of seven walked into a small courtroom. The children's lawyer and social worker were there. With just a few words, our adoption was finalized. These two amazing children weren't going home, because they were already home. We are their forever family, and they are our forever children. We may not be able to change the entire world, but we have changed the world entirely for our new children.

8 . Posing for a picture and flashing the V sign may expose your fingerprints, giving criminals an opportunity to steal your important information.
Researchers with the National Institute of Informatics in Japan successfully got fingerprint information from a picture during an experiment, even though the subject was photographed from three meters away, according to the newspaper.
“Once you share them on social media then they’re gone. Unlike a password you can’t change your fingers.”
Biometric（生物统计的） security is reaching the mainstream with more than 50 percent of mobile phones set to include fingerprint recognition for the first time in 2017. The technology is also used in immigration control and for access to high-security controlled areas.
Photos that include both people's faces and fingers run a higher risk of revealing personal information, and the risk for celebrities is even higher.
Chinese experts in fingerprint identification confirmed the possibility. "Technically, we can use high-definition video cameras to obtain people's fingerprints," said Dr. Yin Desen of the First Institute of the Ministry of Public Security. He also said that people's external features are easily recorded. However, compared to video, it is more difficult to obtain fingerprints through just one photo.
According to experts, criminals are able to use counterfeit fingerprints to commit crimes, such as stealing fingerprint passwords and signing agreements. Yin warned that people should pay more attention when they leave fingerprints or use them as passwords.
1. What is the difference between passwords and fingerprints?| A．Passwords can be changed. |
| B．It is simple to recognize fingerprints. |

9 . We recognize our friends’ faces. And we’re not alone. Many social animals can identify individuals of their own species by features of their faces. That's important, because they need to be able to change their behavior depending on who they meet. And a recent research has shown that some species of monkeys, birds, and domesticated (家养的) animals can even tell different faces apart by looking at photographs alone.
Ethologist Léa Lansade of the French National Research Institute for Agriculture, Food and Environment did an experiment to find out how well horses can recognize individual people in photographs.
She and her team first taught the horses how to “choose” between two side-by-side pictures by touching their noses to a computer screen. The horses were then shown photos of their present keeper alongside faces of unfamiliar humans. They had never seen photos of any of the people before. The horses correctly identified their current keeper and ignored (忽视) the stranger’s face about 75%of the time. In fact, even though the horses didn't get it right every single time, they were at least as correct in picking out their earlier keeper as they were at identifying their present one.
The results suggest that not only can horses differentiate between familiar and unfamiliar human faces, they also naturally understand that photographs are two dimensional representations (二维呈现) of real life, without any other intimations such as smell or sound. And they’re even better at this than our oldest animal parter, the domestic dog.
In addition, horses seem to have a strong long-term memory for human faces, like their long lifespan and history of domestication. In future experiments, the researchers would like to test whether looking at photos of people that they have had bad experiences with in the past might cause horses to act anxious or even avoidance. So maybe think twice before doing anything that might give a horse a long face.
1. Why did researchers show the horses both the keeper’s photos and the strangers’?| A．To find out what horses would do in the experiment. |
| B．To see why horses could recognize the keeper in the pictures. |
| C．To test whether horses could recognize the strangers in pictures. |
| D．To study to what degree horses can make out different people in pictures. |
| A．Clues. | B．Differences. |
| C．Photographs. | D．Senses. |
| A．Whether horses can live longer than other animals. |
| B．Whether horses can remember human's faces for a long time. |

In Darrel Gregory’s encouraging picture book I’m Not Very Good at It, a mother suggests a means for her daughter to handle her low self-esteem.
The story centers on a downcast girl, who, when asked to do anything, tells herself, “Okay, but I’m not very good at it.” These words are voiced aloud whether she’s making a birthday card, baking, or helping her mother with a bird house. When her mother asks her why she responds in this manner, the girl replies, “Because that’s what my brain said.” Through a series of playful explanations, her mother advises her to listen to her heart instead. After a few attempts at practicing this new habit, the girl realizes that being good at something----or not!----is not as important as trying.
The story’s repetitive structure emphasizes its therapeutic message about stopping self-doubting talk and about practicing stillness. Though perfectionism and fear of failure are possible explanations for the girl’s behavior, the specific reasons and context for her self-doubt are absent. It is a depersonalized story whose heroine is generic, nameless, and tough to connect with. She is preschool-aged, but is asked to possess great self-awareness about her own personality and to shift her own features----it happens too early for a preschool-aged child, if not idealistic.
Ari Miller’s soft illustrations(插图) make the text vivid. Their detailed home scenes portray the girl’s activities. They are faithful depictions of the story that track the girl’s emotional change through subtle facial expressions. The girl’s mother is left out of these images, though her advice and support is one of the main features of the story.
Sincere in its description of growing past self-doubt, the picture book I’m Not Very Good At It encourages positive outlooks.
1. What type of writing is the text?| A．A report | B．An advertisement. |
