Recordings of angry bees are enough to send big, tough African elephants running away, a new study says.Beehives (蜂窝) — either recorded or real — may even prevent elephants from damaging farmers' crops.
In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them.Today, Lucy wants to see if African honeybees might discourage elephants from eating crops.But before she asked farmers to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.
Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder.Then she threw a stone into the beehive, which burst into life.Lucy and her assistant hid in their car until the angry bees had calmed down.Next, Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.
From a distance, Lucy switched on the prerecorded sound of angry bees while at the same time recording the elephants with a video camera.Half the elephant groups left the area within ten seconds.Out of a total of 17 groups, only one group ignored the sound of the angry bees.Lucy reported that all the young elephants immediately ran to their mothers to hide under them.When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed.Even after four minutes, most of the groups stayed in one place.
Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times.She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers.She has now begun placing speakers in the fields to see if elephants are frightened away.
1.We know from the passage that elephants may be frightened of ________.
A.loud noises B.some crops
C.video cameras D.angry bees
2.Why did Lucy throw a stone into a wild beehive?
A.To record the sound of bees.

Happy, angry, amazed—these are some of the emotions we like to express these days when we’re sending a message on our smart phones. That’s why many of us now add little pictures to our texts to brighten up someone’s mobile screen but we’re also using them as a quick way of telling someone how we’re feeling. Yes, emojis have become a vital tool for communication.
Let’s clear one thing up first—there are emojis and emoticons (表情符号). The latter are little images made using normal keys on a keyboard. For example, a colon, two dots, followed by the curved line of a close brackets is a “smiley face”.
The emoji was first invented in Japan in the late 1990s and the word “emoji” comes from the Japanese words for “picture” and “character”. The number of different images has dramatically increased since then and now we have a picture for every mood or situation.
So now we have the option to give this new creation the visual “thumbs-up” but have you thought why we’ve become so addicted to using emojis? Professor Vyv Evans who has written a book called The Emoji Code says, “What we’re finding is that digital communication is taking over from certain aspects of face-to-face interaction…One of the reasons emojis are so interesting is that they really do enable us to express our emotional selves much more effectively.”
Another advantage of emojis is that they are an international language—they don’t use words but tell a message in pictorial form so they can be easily interpreted whatever your native language.
Emojis are a good way for showing empathy (共鸣)—they are a virtual hug or an adorable tease. But as linguist Neil Cohn says, “To many, emojis are an exciting evolution of the way we communicate while to others, they are linguistic (语言学的) Armageddon.” It does show there is a lot more to our communication than words alone but does this mean the decline in traditional writing?
1.What is the main idea of the passage?
A. The decline in traditional writing.
B. The differences between emojis and emotions.
C. The origins of the emoji.
D. The rise of the emoji.
2.Why are emojis appealing according to Professor Vyv Evans?
A. Because they are easy to use.
B. Because they allow us to express whatever we want.
C. Because they enable us to express our feelings better.
D. Because digital communication has taken the place of face-to-face communication.
3.What can we know according to the passage?
A. An emoji is a small picture which is made using normal keys on a keyboard.
B. The emoticon appeared in Japan for the first time.
C. People including linguists all become crazy about emojis now.
D. Emojis have become a more effective tool to express our feelings in modern society.
4.What does the underlined word “Armageddon” probably refer to?
A. Nightmare. B. Excitement.
C. Preference. D. Future.

[1] One of the tough things about being a high school student is that you never Seem to get enough sleep at night, which often leaves you nodding off during classes.The best amount of sleep is about seven and a half to eight hours.Spending either less than six or more than nine hours in sleeping puts your health at risk.
[2] A popular solution to a lack of sleep at night is to take a “power nap” during the day, but does this work?
[3] Generally speaking, it can be beneficial.Research shows that a nap in the middle of the day—even a brief one as Short as five or 10minutes—can clear your mind and leave you with increased energy and improved productivity.
[4] But here are some things you need to know to do it correctly.To start with, every time you doze off (打瞌睡) during the day does not count as a “power nap”.The best time to take a power nap is in the mid-afternoon, when your energy level tends to decrease.
[5] But how long should a power nap be? Ideally, it should be kept to between 10 and 30 minutes.Nodding off for five minutes does not really provide established sleep.If you, however, go into the deeper stage you will wake up feeling weak.
[6] However, refreshing as it might be, if you get adequate sleep at night, taking a power nap isn’t such a wise choice.The reason is that sleeping during the day can interfere with your body’s biorhythms.The brain gets used to going to bed and getting up at roughly the same time each day, and you don’t want to disturb this routine.
[7] One more thing to keep in mind is that a power nap should never be used as a replacement for a good night’s sleep.A power nap during the day is not like a tablet which will definitely work.An hour’s sleep before midnight is worth a couple of hours’ sleep after midnight.

Eating red meat is linked to cancer and heart disease, but are the risks big enough to justify giving up juicy burgers and delicious steaks? Probably not, according to researchers who reviewed data from 12 clinical trials involving about 54,000 people. In a series of controversial papers, the researchers argue that the increased health risks tied to red meat are small and uncertain, and that cutting back likely wouldn't be worth it for people who enjoy meat.
Those conclusions go against established medical advice. They were swiftly attacked by a group of famous U.S. scientists who took the unusual step of trying to stop the papers from being published until their criticisms were addressed.
The new work does not say red or processed meats like hot dogs and bacon are healthy, or that people should eat more of them. The team’s reviews of past studies generally support the ties to cancer, heart disease and other bad health outcomes. But the authors say the evidence is weak, and that there’s not much certainty meat is really the cause, since other diet and lifestyle factors could be at play.
If the latest example of how divisive nutrition research has become, with its uncertainties leaving the door open for conflicting advice. Critics say findings often aren't backed by strong evidence. Defenders counter that nutrition studies can rarely be conclusive because of the difficulty of measuring the effects of any single food, but that methods have improved.
Based on their analyses, the researchers said people do not have to cut back for health reasons. But they noted that their own advice is weak, and acknowledged that they didn't consider factors such as animal welfare and the environment. Indeed, the case that meat production is bad for animal welfare and the environment is stronger than the case that it's bad for human health, according to an editorial that accompanies the report.
Not all of the report authors agreed with its conclusions. Three of the 14 researchers said they support reducing red and processed meats. A coauthor of one of the reviews is also among those who called for a publication delay.
Those who pushed to postpone publication also questioned why certain studies were included in the reviews while others were left out.
As for his own diet, Dr. Gordon Guyatt, a member of the international research team that conducted the reviews, said he no longer thinks red or processed meats have significant health risks. But he said he still avoids them out of habit, and for animal welfare and environmental reasons.
1.What is the author’s purpose in writing the passage?
A.To introduce a new relationship between health and eating red meat.
B.To urge more people to keep away from eating red meat regularly.
C.To present a new controversial view on impacts of eating red meat.
D.To criticize nutrition studies for lacking of conclusive evidence.
2.What is the author’s attitude towards the new research?
A.Doubtful. B.Positive.
C.Disapproving. D.Objective.
3.Guyatt’s avoiding red meats has the weakest connection with ________.
A.health risks B.diet habits
C.animal welfare D.environmental protection
4.What can we learn from the recent research?
A.Red meats don’t have significant health risks.
B.Reducing meat consumption will be worth it.
C.The report authors have reached a consensus.
D.Consuming red meat will do good to health.

We Chinese are not big huggers. A handshake or a pat on the shoulder is enough to convey our friendship or affection to one another. So when our newly-acquainted Western friends reach out in preparation for a hug, some of us feel awkward.
Many questions go through our head. Where should I put my arms? Under their armpits or around their neck? What distance should I maintain? Should our chests touch?
It’s even more difficult with friends from some European countries. Should I kiss them on the cheek while hugging? Which side? Or is it both cheeks? Which side should I start on?
But it isn’t just people from cultures that emphasize a reservedness in expressing physical intimacy(亲密) who find hugging confusing. Hugs can cause discomfort or even distress in people who value their personal space.
In a recent article for The Wall Street Journal, US psychologist Peggy Drexler said that although the US remains a “medium touch” culture — “more physically demonstrative than Japan, where a bow is the all-purpose hello and goodbye, but less demonstrative than Latin or Eastern European cultures, where hugs are strong and can include a kiss on both cheeks”, Americans do seem to be hugging more.
From politicians to celebrities, hugs are given willy-nilly to friends, strangers and enemies alike; and the public has been quick to pick up the practice. Public figures know that nothing projects like the ability as a good hug. US First Lady Michelle Obama has put her arms around icy foreign leaders like Russian Prime Minister Dmitry Medvedev and the Queen of England, on the latter occasion actually breaking the rule of royal manners.
But not all are grateful to be embraced, even by the most influential and famous. To them, any hug is offensive if it’s not sincere.
Amanda Hess, writing for US magazine Slate, says public figures should stop imposing hugs on everyone they meet. For them, a hug is rarely a gesture of sincere fellowship, compassion or affection. It’s all part of a show. Hugs are falsely intimate power plays used by public figures to establish their social dominance over those in their grasp.
Cecilia Walden, a British journalist writing for The Telegraph who lives in New York, holds the same opinion. “Power-hugging”, as she calls it, is “an offender dressed up as kindness”. It has become a fashion in the US where “bosses are already embracing their staff (either shortly before or after firing them), men and women ,their friends or enemies, in a thousand cheating displays of unity”.
1.From the first four paragraphs, we can see that ___________.
A. we Chinese people don’t know how to hug
B. people from European countries often get puzzled about hugging
C. people in Western countries seldom use hugs to express their physical closeness
D. hugs can bring pressure to people when used improperly
2.The example of US first lady Michelle Obama is given to show that __________.
A. Americans hold a “medium touch ”culture
B. public figures know hugging functions well in public
C. she is much liked by American people
D. hugs are forbidden in England
3.“Power-hugging” in the last paragraph actually means that _________.
A. hugs are only used sincerely by some people with power
B. hugging is powerful to bosses in US
C. public figures sometimes use hugging just for a show of power
D. public figures can hug anyone in their grasp freely
4.What can be the best title of this passage?
A. Hugs, vital or not? B. Hugs, tricky affair?
C. Hugs and public figures D. Hugs and power

Many electronic parts are made of hard materials that break easily. That makes them tough to use in products that need to bend. Now, Sam Yoon and his team have developed a thin mesh (网状物) that can both bend and conduct electricity.
His team started out with something called acrylonitrile, a clear liquid often used to make thin plastic fibers. Yoon and his team mixed this material with another liquid, which acted as a solvent. A solvent is something that can make other substances into liquids. Then, they squeezed the mix through a very tiny pipe: As the mixture was sprayed through the air, the solvent evaporated(挥发)and the acrylonitrile molecules linked up to make long chains, creating a type of plastic known as PAN. The researchers continually squeezed the mixture through the pipe. A single long PAN fiber was created. The scientists moved the pipe back and forth as the PAN was squeezed out. It ended up creating a layer that looked something like a spider’s web.
PAN, like most plastics, doesn’t conduct electricity. So the team’s next step would normally be to add a coating of metal so that electricity could flow through it. But it could be tough sticking such coatings on PAN. So the researchers added an extra step. They sprayed a thin coating of an inert metal onto the PAN. Inert metals, like gold, typically don’t react with other materials. The researchers then added another layer of PAN fiber at the top of the first, web-like layer. They provide temporary support, helping the metal-sprayed base resist sinking during the next step.
The researchers connected the fiber-covered frame to a negatively changed electrode. Then they dipped the fiber-covered frame into a solution that included the liquid copper. The team turned on the electric current for about one minute to make it run through the solution. The copper in the solution was attached to all of the fibers. But it stuck only to those that wore a metal jacket. Besides adding a thin layer of copper that conducts electricity, this process helped bond the PAN strands together at places, where they touched each other, Yoon notes.
The researchers then attached all of the fibers to a thin, clear layer of plastic, which had sticky backing, like a Band-Aid. Finally, the team dipped all of these into a liquid that made any of the PAN fibers that lacked a copper jacket into liquids. Only those that can be used to conduct electricity were left. Because the fibers were very thin and widely separated, light waves easily travel through the mesh. The copper coating acted just like a wire, permitting electricity to flow freely across it.
1.The team used another liquid in the process to .
A.make acrylonitrile evaporate B.turn acrylonitrile into plastic fibers
C.make acrylonitrile conduct electricity D.conduct electricity instead of acrylonitrile
2.What should the team do first when using PAN?
A.Make it easy to break. B.Make it react with other materials.
C.Make it conduct electricity. D.Find a way to make it into a liquid.
3.What does the underlined word those in the last paragraph refer to?
A.The thin plastics. B.Just the copper coatings.
C.All the PAN fibers. D.All the copper-coated fibers.
