While you’re hiding away the Christmas presents, animals are storing food for the winter! Many animals “cache” (贮藏) or hide food for time to come, similar to how we stock our pantries with food. In the winter months, caching allows animals to survive when food is scarce.
Some animals, such as bobcats and mountain lions, leave dead animals’ bodies for short periods of time buried beneath surrounding vegetation. Other animals, such as rodents and birds, store seeds for long periods of time in places they’ll return to weeks or even months later.
Hiding food throughout an animal’s home range is known as scatter hoarding. This keeps the caches low and less enticing to any potential thieves. However, this technique requires a good memory, as the food is often in dozens, if not hundreds, of different locations.
Another caching technique involves animals collecting food in only a couple of places, referred to as larder hoarding. These caches are often found in cavities such as a hollow tree or a hole in the ground. They are easier to find but require lots of defensive measures.
Here are some of the animals that cache in the Peach State:
Birds such as chickadees, nuthatches, titmice and jays can store hundreds of seeds in a single day. Each seed is placed in a different location, and they usually remember where each is, even months later. Flying squirrels store a variety of seeds, nuts and acorns in their nests and in trees. These nocturnal squirrels will even bury seeds in the ground. It is believed that a single lying squirrel can store over 15,000 seeds in a year! Moles trap live earthworms underground. The mole bites the earthworm’s head off, and colder temperatures slow the earthworm down. If the weather warms up before the mole has a chance to consume its prey, however, earthworms can regrow their heads and tunnel their way to freedom.

【推荐1】In a little over a decade, Manas National Park, located in the northeastern India state of Assam, has seen great growth in its. greater one-horned rhino(独角犀牛) population. Plans for bringing rhinos back to Manas National Park were developed in2005, and translocations(转移) began in 2008 with individuals moved to Manas from other protected area in Assam.
During the first translocation in 2008, two adult males were successfully moved from Assam’s Pobitora Wildlife Sanctuary to Manas. Over the next four years, 16 more rhinos were translocated to Manas from Kaziranga National Park and Pobitora. The translocated rhinos were radio-collared(套上无线电颈圈) to know about their health, movement, and behavior, and obtain important data for better management and conservation rhinos in the future. Before the translocations, the park was built to provide conditions for protecting the rhinos, since their safety is always a key consideration once the rhinos are moved.
Since 2008, 20 rhinos have been translocated and all translocated females have given birth at least once since they were moved to their new homes, with 26 babies born by April 2020.
Translocation are just one part of rhino conservation. Local communities that live near or share rhino habitats play an important role in helping to keep their population safe. The local government and many people have led efforts to involve local communities in conservation. They have provided support to local community conservation organizations in and around Manas to raise awareness on the importance of conservation in their area and train youth and other community members to help protect the park. In addition, these partners have been supporting communities to develop local tourism and offering communities to develop tourism in the area, which brings in additional livelihood opportunities.
Today, there are around 3,700 greater one-horned rhinos in Asia, up from only 200 at the beginning of the 20th century. While the species continues to face threats from hunting, signs of population growth like those from Manas are certainly cause for hope.

【推荐2】In Canada, you can find dogs, cats, horses, etc. in almost every family. These are their pets. People love these pets and have them as their good friends.
Before they keep them in their houses, they take them to animal hospitals to give them injections (注射) so that they won’t carry disease. They have special animal food stores, though they can get animal food in almost every kind of store. Some people spend around two hundred Canadian dollars a month on animal food. When you visit people’s houses, they would be very glad to show you their pets and they are very proud of them. You will also find that almost every family has a bird feeder in their garden. All kinds of birds are welcomed to come and have a good meal. They are free to come and go and nobody is allowed to kill any animal in Canada. They have a law against killing wild animals. If you killed an animal, you would be punished. If an animal happened to get run over by a car, people would be very sad.
People in Canada have many reasons to like animals. One of them might be: Their family ties are not as close as ours. When children grow up, they leave their parents and start their own life. Then the old will feel lonely. But pets can solve this problem. They can be good friends and never leave them alone.
1. The passage mainly talks about ________.A.how to keep disease from pets | B.pets in Canada |
C.how to take good care of pets | D.life of the old in Canada |
A.the pets are sick | B.the pets are wild |
C.they want to stop them from carrying disease | D.they want them to sleep on the way home |
A.hate animals | B.often kill animals | C.love animals | D.don’t keep pets inside houses |
A.they don’t love their parents any more | B.they can only find jobs far from their parents |
C.their parents’ houses are too small | D.they wouldn’t depend on their parents any more |
Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator(猎食动物)gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.
Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.
Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.
Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.
Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them, and they don't need to share their food.
As is mentioned above, animals behave dishonestly for survival. Is it OK to lie for us human?

【推荐1】I’m the youngest of five children. By the time I was six, my siblings were gone, and we went from a very noisy house-hold to a very quiet one. My family has told me stories about how my siblings teased me in those years before they left. But I can recall very few stories of my own from that time.
Hardly any adult can. This is called infantile amnesia—the inability to recall the experience of early years. There has been a century of research about whether these memories are tucked away in some part of our brains and need only a reminder to be recovered. But research now suggests those memories simply disappear.
Psychologist Carole Peterson has conducted studies of children between the ages of 4 and 13, finding that people can’t recall much that happened before seven. In both children and adults, memory is strangely selective about what is left and what is gone.
“So much has to happen biologically to store a memory,” psychologist Patricia Bauer said. There’s “a race to get it stored before you forget it. It’s like making Jell-O: your mold (模型) has a tiny hole in it. You just hope your Jell-O — your memory — gets set before it leaks out through that tiny hole.”
Some people have more memories from early childhood than others do. Peterson found that children in China have fewer of these memories than children in Canada do. The finding might be explained by culture: Chinese people prize individuality less than North Americans and thus may be less likely to draw attention to the moments of an individual’s life.
If we can’t remember much from those years, does it matter what actually happened? Bauer says yes. Even if we don’t remember early events, they leave an imprint on the way we understand and feel about ourselves, other people, and the greater world. We aren’t just the sum of our memories, or at least not entirely. We are also the story we construct about ourselves. And that’s a story that we will never forget.
1. Why does the author mention his early childhood experience in Para.1?A.To show great regret for his lack of memory from early years. |
B.To compare his childhood life before and after his siblings left. |
C.To arouse readers’ curiosity about the blank memories of early years. |
D.To entertain readers with his interesting early childhood experience. |
A.By conducting research. | B.By giving examples. |
C.By analyzing cause and effect. | D.By making a comparison. |
A.Memories of early years can be easily recovered with a reminder. |
B.Memories of early years vary among people for cultural reasons. |
C.Memories of early years are stored in people’s mind at random. |
D.Memories of early years have no influence on people at all. |
【推荐2】We are all busy talking about and using the Internet, but how many of us know the history of the Internet?
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way, computer network system would keep on working all the time.
At first the Internet was only used by the government, but in the early 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers had become cheaper and easier to use. Scientists had also developed software that made “surfing” the Internet more convenient.
Today it is easy to get online and it is said that millions of people use the Internet every day. Sending email is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.

【推荐1】A new survey reviews that more than 60% of websites and apps intended for Canadian children may be collecting personal information and passing it on to a third party. The survey was completed by the Global Privacy Enforcement Network, which reviewed 1,494 websites and apps.
Focusing on trends among Canadian users, the sweep team reviewed 118 websites and apps targeted directly at children, as well as 54 that are known to be popular with and used by kids. The team’s findings showed that more than 50% of Canadian sites collect personal information from children, including names, addresses, phone numbers and photos, audio or video. In addition, 62% of sites admitted they may show that personal information to third parties. Another 62% allowed the user to be redirected to a different site, and only 28% of the sites and apps involved any form of parental control or protection.
A member of the team Tobi Cohen, outlined a few of the sites that did and did not live up to the standards of children’s privacy online. She praised both Family.ca and Lego.com for their message boards that did not allow users to post personal information, and noted that santasvillage. ca asked users to provide their full name and email address. Gamezhero.com was also singled out for allowing users to display personal information, including names, age, sex and locations. Pbskids.org, on the other hand, was praised for only offering generic, pre-set avatars (头像) and barring users form uploading personal photos.
The Office of the Privacy Commissioner of Canada refused to release a full list of the websites and apps reviewed. When asked what would be done with results, commissioner Daniel Therrien said that companies reviewed in the sweep would be kept informed of the findings. “It’s our usual practice after conducting a sweep to write a number of companies to point out the things that we’ve seen, to sometimes ask that things be changed, and on the whole the companies react positively to these requests.” Therrien added.
In an attempt to help kids better understand why their privacy matters, the Office of the Privacy Commissioner of Canada has created a lesson plan for kids in Grade 7 and 8 that explains the Global Privacy Enforcements Network and has kids conduct privacy reviews of their own.
“We know that companies are not the only ones responsible for the protection of kids’ privacy.” Therrien said. “Parents and teachers obviously have a role. We have a role, particularly in the area of increasing awareness of privacy issues among the public.”
Matthew Johnson, director of education at Media Smarts, said that the sweep’s results were sadly unsurprising. Media Smarts, an Ottawa-based non-profit digital literacy outfit intended to improve media literacy and empowering the youth to better engage with media, offers age-appropriate tips to parents concerned with keeping their kids safe online.
Johnson explained that in addition to educating themselves on the issue, the best thing parents could do to protect children’s privacy online is to educate kids on the importance of the function of their personal data. He mentioned an initiative by Media Smarts called Privacy Pirates, an online game that aims to teach kids at the age of seven to nine that all forms of personal information should be protected and added that their personal information has value and they should think twice before giving it out.
1. We can conclude from the data mentioned in Paragraph 2 that ________.A.parents must be to blame for letting out their kids’ privacy |

【推荐2】An international team of researchers from the University of Ox ford have found that the way people use the Internet is closely tied to seasonal movements in the natural world. Their online species searches follow the patterns of seasonal animal migration.
Migratory birds flood back to where they reproduce (繁殖) each spring. That migratory behavior is accompanied by some human behavior. “The online searches for migratory species tend to increase in spring when those birds arrive in the United States,” said the lead author John Mittermeier.
And not just birds. Mittermeier and his team surveyed nearly 2.5 billion search records, for 32,000 species, across 245 languages. They also saw variable search rates for insects and flowering plants. Seasonal trends seemed to be widespread in online searching behavior for many species of plants and animals.
This finding suggests new ways to monitor changes in the world’s biological diversity. It also shows new ways to see how much people care about nature, and which species and areas might be the most effective targets for protection.
Mittermeier is encouraged by the search results. He commented, “I think there’s a concern among conservationists (环保主义者) that people are losing touch with the natural world and that they are not interacting with native species anymore. And so in that sense, it was really exciting and quite unexpected for me to see people’s interest closely related to changes in nature.”
Richard Grenyer says search data is useful to conservation biologists, “By using these big data approaches, we can direct our attention towards the difficult questions in modern conservation: which species and areas are changing and where are the people who care the most and can do the most to help.”

【推荐3】Green therapy: how gardening is helping to fight depression
A growing movement is promoting the role gardening can play in patient recovery.
Sydenham Garden feels out of step with its surroundings in urban south London. Surrounded by houses on most sides, with a school on its doorstep, it is hard to imagine that this small patch of green space is bringing a new life to people struggling with their mental health. The site, run by the Sydenham Garden charity trust, is just under an acre and has a well-being centre with gardens, a nature reserve and activity rooms. Therapeutic(治疗的)gardening activities are held weekly, and are run by experienced staff, who are in turn supported by a team of volunteers.
Christine Dow, 63, was originally referred to the garden by her GP to help overcome her depression. After a year of "green" therapy, she became a volunteer, for the past decade she has spent a few hours every week supporting others referred to the project.
During 2017-2018, Sydenham Garden received 313 patient referrals(转诊)from health professionals. A typical referral will be between 6 and 12 months. Most people referred will score in the low well-being category-according to the Warwick-Edinburgh scale-when starting, but score in the moderate well-being category upon completion. It is part of a growing movement devoted to increasing the role that gardening and other forms of "green" therapy cam play in patient recovery. It is also one of the 1,500 organizations signed up to Growing Health, a national project set up by the charity Garden Organic and the membership organization Sustain.
"Gardening is not for everyone," says Maria Devereaux, a project officer at Sustain. "But,increasingly now, we've got evidence that even people who aren't gardeners are able to harvest the benefits of being outside working with nature and all the things that come with it." Evidence collected by Growing Health found simply viewing a green space through a window could help people relax and reduce stress levels. Other evidence confirmed that the physical activity of gardening could improve mental wellbeing.
