A device that uses the sun is a good way to dry food. There are several kinds of solar dryers. The easiest to build is called the direct dryer. The sun shines directly on the food being dried. The direct dryer is a box with holes in it so that air can enter and leave the box. It has a cover made of clear glass or plastic. When the sun shines into the box, heat is produced. The heat is trapped inside the box and cannot escape back through the cover. The heat dries the food.
The solar dryer works better if the sides of the box are black. This is because dark colors hold heat while light colors reflect it. One way to make the sides black is to use wood that has been blackened by fire.
If you use black paint instead, be sure the paint contains no lead. Lead is poisonous to people, especially children.
The box can be made of almost any material such as wood, concrete or sheet metal. The dryer should be two meters long, one meter wide and twenty-three to thirty centimeters deep. The sides and bottom should have additional material, called insulation, to keep the heat from escaping.
The surface on which the food is placed should permit air to enter from below and pass through to the food. A surface made of wires with small square openings works very well. You should use wire with the largest openings or squares that do not allow the food to fall through. Air that comes in from below the wire surface will also carry away water evaporated from the food as it dries.
A direct dryer will dry most vegetables in two-and-one-half to four hours at temperatures from forty-three to sixty-three degrees Celsius. Fruits take longer, from four to six hours at the same temperatures.
Solar food drying is fast, safe and low-cost. It is also healthy because nutrients such as vitamin C are kept in the food. Solar dried food also tastes and looks good.

【推荐1】Many of us have wondered what Earth is like beneath the surface. So have writers and scientists. In French novelist Jules Verne’s masterpiece Journey to the Center of the Earth, explorers go down to Earth’s center and discover amazing wonders.
But in real life, human beings haven’t even come close to the planet’s core (核心). The core is over 6,000 km down. The deepest hole ever created, according to the BBC, is the Kola Superdeep Borehole in Russia, which only goes 12.3 km down.
So how do we know about everything down below without any samples？
One good way to start is to think about the Earth’s density (密度), Simon Redfern of the University of Cambridge in the UK told the BBC.
“The density of the material on Earth’s surface is much lower than the average density of the whole Earth, so that tells us there’s something that has greater density,” Redfern said.
The challenge is to find out which heavy materials the core is made of. And the main material scientists have found is iron. The idea is that when Earth formed 4.5 billion years ago, a lot of iron made its way down to the core, taking up about 80 percent of it. Today scientists are still working on finding out which other materials the core could be made up of.
You might also wonder how we know the size of the core. There’s a one-word answer: seismology (地震学).
When an earthquake happens, seismic stations around the world record the shockwaves it sends throughout the planet. It’s like hitting one side of the planet with a huge hammer and listening on the other side for the noise.
Early research found that some shockwaves, called “S-waves”, went missing. S-waves can only travel through solid material, but not through liquid, so they must have found something molten in Earth’s center. By following the S-waves’ paths, scientists found out that rocks became liquid around 3,000 km down.
There are still many questions about the Earth’s core to answer. But the study of the dark world below isn’t just for scientists’ curiosity.
The movement of Earth’s molten iron core builds up a powerful magnetic (有磁力的) field. It protects us from radiation from the sun and is needed for compasses and GPS systems to work.
So perhaps none of us will ever set eyes on the core, but it’s good to know it’s there.

【推荐2】Do you find getting up in the morning so difficult that it’s painful? This might be called laziness, but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labor (努力) through your work you may say that you’re “hot”. That’s true. The time of day when you feel most energetic is when your cycle of body temperature is at its peak. For some people the peak comes during the morning. For others it comes in the afternoon or evening. No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: “Get up, John! You’ll be late for work again!” The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean, and which cycle each member of the family has. You can’t change your energy cycle, but you can learn to make your life fit it better. Habit can help, Dr. Kleitman believes. Maybe you’re sleepy in the evening but feel you must stay up late anyway. Counteract (对抗) your cycle to some extent by habitually (习惯地) staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day, rise before your usual hour. This won’t change your cycle, but you’ll get up steam (鼓起干劲) and work better at your low point
Get off to a slow start which saves your energy. Get up with a leisurely yawn (哈欠) and stretch (伸懒腰). Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for clean clothes by laying them out the night before. Whenever possible, do routine (常规) work in the afternoon and save requiring more energy or concentration for your sharper hours.

【推荐3】Facts about novel corona virus: Prevention and control
l Keep distance with people when talking
The novel corona virus can be transmitted via droplets and fly 1 to 2 meters in the air before falling to the ground. Droplets can be transmitted far longer when sneezing and coughing than speaking, so apart from keeping 1 to 2 meters of distance, also remember to wear a mask when you are close to someone else.
l Washing hands can reduce risk of getting infected
Please wash your hands promptly and properly after touching elevator buttons or using cash. Do not touch your nose or mouth or rub your eyes before washing your hands. Do not use smart phones while eating.
l Receiving delivered packages at home not dangerous
Though the virus might be attached to the packaging of delivered items, the possibility of transmission through express delivery is extremely low. Before going out to take your delivery, remember to wear a mask. After removing the packaging, please wash your hands.
l Sun exposure cannot kill the virus
The temperature of sun light cannot reach 56℃, and the ultraviolet rays in sunlight cannot reach the intensity of ultraviolet lamps, so the virus can’t be killed by the sunlight. If you want to go out to get some sun, please wear a mask and take other protective measures.
l Taking a hot bath or using air conditioning cannot kill the virus
Although the virus is vulnerable to heat. It can only be inactivated after exposure to a 56°C temperature for over 30 minutes.
l Woolen fabric doesn’t retain virus longer
It is believed that the virus prefers smooth, non-porous surfaces and stays on woolen fabrics for a shorter time. At home or before going out, it is not necessary to consider which kind of material has less chance to absorb the virus—choosing comfortable clothes is enough.
After returning home, please wash your hands, sterilize the clothes and dry the clothes.

【推荐1】When you step on an escalator (自动扶梯), do you stand to one side to let others pass? When someone in the room fans himself with a piece of paper, do you open a window? If you ask someone to hang out with you and they stare at you blankly, do you withdraw the invitation? If you don’t do any of these things, I have some unfortunate news: you cannot “read the air”.
Knowing the unspoken rules governing social life requires a comprehensive understanding of your environment, whatever its setting. It’s a skill that’s valuable anywhere in the world—but in Japan, it is raised to another level. Reading the air—kuuki o yomu in Japanese—is a constant exercise. Misreading the air can blow business deals or ruin relationships.
Rochelle Kopp, who runs a cross-cultural training firm Japan Intercultural Consulting, says that while all nations have varying degrees of indirect communication, in Japan the phenomenon is more prominent in society. For example, if you’re talking to a client who has long since lost interest, you risk being labeled KY—a pejorative Japanese slang term that stands for “kuuki ga yomenai”, or “unable to read the air”.
A big part of “reading the air” is picking up on non-verbal cues. David Matsumoto, a psychology professor at San Francisco State University, studies micro-expressions: tiny involuntary facial tics that can give away a person’s true emotions. When, for example, a client at work says they’re happy with the job you’re doing, a very subtle lip twitch or eyebrow raise could mean they’re not telling you the truth. Noticing micro-expressions, along with other non-verbal communication, is important in any interaction, no matter where you are.
“Silence is one non-verbal signal. So is shifting of posture. A social smile could be yet another signal,” says Matsumoto. “All of these are part of the non-verbal package that contributes to that contextual meaning.” Matsumoto runs Humintell, a company that provides workshops on how to get better at reading micro-expressions and other non-verbal signals. Others provide such services, too; in Tokyo’s Toranomon business district, researcher Kenji Shimizu runs the Institute for Science and Being Sensitive to the Situation.
Like Matsumoto, Shimizu teaches people how to master micro-expressions. Shimizu uses a system developed by U.S. psychologist Paul Ekman, who coined the term and described the subtle facial changes as “involuntary emotional leakage”. “If you notice someone’s disgust (厌恶) —wrinkling around the nose—or anger—brows lowering, eyes widening, lips pressing—and yet those expressions are masked by smiles, you may want to figure out their actual thoughts.” Shimizu says.

【推荐2】Do you need to throw your smartphone away to live your best life? Not necessarily, according to researchers from Ruhr-Universität Bochum who suggest that we could all benefit from cutting down on screen time – just only a little bit time.
On average, we spend more than three hours a day looking at our smartphone screens. Between social media, news feeds, endless video games, and an app for pretty much everything else, there’s always something to draw our attention. In recent years, researchers have found connections between smartphones and many modern problems ranging from increasing anxiety cases to neck pain. So here comes the question: Are people all really better off changing back to landlines (座机)?
“The smartphone is both a benefit and a danger,” says study leader Dr. Julia Brailovskaia, whose team set out to answer that question by gathering together 619 volunteers, hoping to know how much the smartphone is good for us. For a week, two hundred people put their smartphones completely aside; 226 reduced the amount of time they used the device (装置) by one hour a day; 193 people didn’t change anything in their behavior.
Researchers interviewed each person about both their lifestyle habits and well-being (健康) four months later after the experimental week ended. “We found that both completely giving up the smartphone and reducing its daily use by one hour had positive effects on the well-being of the participants (参与者),” as Brailovskaia studies and reports the upshots. Especially, changing their smartphone habits for just one week appeared to produce lasting outcomes among volunteers. Even four months afterward, participants who were told to avoid using their smartphones totally were using their phones for an average of 38 minutes less per day.
Meanwhile, the “one hour less” group were using their phones as much as 45 minutes less per day after four months. This group also showed improved life satisfaction, more exercise, and less depression (抑郁). “It’s not necessary to completely give up the smartphone to feel better,” Brailovskaia concludes.
1. What can we know about the volunteers in the research?| A．They received some training beforehand. |
| B．They were divided into two groups. |
| C．They were interviewed months later about their habits and health. |

【推荐3】When it comes to making healthy lifestyle changes, which should come first—changing your diet or becoming more physically active?
Previous studies suggested that providing people with too much information about nutrition and physical activity at once tends (趋向)to be discouraging. That has led to the popularity of advising people to make changes gradually, and set smaller goals.
So the scientists divided 200 inactive participants who were 45 or older into four groups. One group was instructed in making diet and fitness changes at the same time; the second group was taught about diet changes first, and then fitness changes four months later; the third group changed their exercise habits first and made changes in their eating habits four months later; and the final, control group was not instructed in either diet or fitness changes but in how to manage their stress.
The researchers followed the groups for a full year. Compared to the control group, the three intervention (干预) groups made healthy changes in their diet. Those who changed their fitness habits first significantly increased the amount of exercise they received daily compared to the other groups after four months. However, at the end of the year, the group that changed both diet and exercise at the same time was the only one that met the nationally recommended targets for both exercise and nutrition levels, while those who worked on improving their nutrition first were unable to meet the recommended levels of fitness after a year. The researchers suspect that changes to diet are easier to make than changes to physical activity.
The findings show, however, that pairing diet and exercise changes may help to overcome some of the barriers people face in adding more physical activity into their lives. If folks change diet and exercise orderly, the scientists say, they may end up placing more importance on the first set of behavior changes and feel less pressured to address the second set.

【推荐1】From visiting museums to watching Changing the Guard, there are some amazing experiences for you to get while in London. Here we pick some of the best free activities in London.
Changing the Guard
For a display (展览) of British ceremony, watch Changing the Guard outside Buckingham Palace. This is where one member of Queen’s Guards exchanges (交换) duty with the old guard. Both guards are dressed in traditional red uniform and bearskin hats, and the handover is accompanied by a Guards band. Guard Mounting takes place at 11:30 am. It is held daily from May to July, and on alternate (间隔的) dates throughout the rest of the year.
Sir John Soane’s Museum
Sir John Soane was an architect. During his lifetime he collected some valuable antiquities (古董) from all four corners of the globe. They are now on display in Sir John Soane’s Museum which gives a real insight into the life of this outstanding Victorian gentleman.
Geffrye Museum
A very unique experience, the Geffrye Museum, located in 18th century almshouses (救济院), gives a fascinating insight into the lives of the British middle classes from the 1600s to the present day. Explore a series of room sets, complete with furnishing and textiles from each period.
Hogarth’s House
Hogarth was very famous and criticized 18th century society in his engravings (雕刻), such as A Harlot’s Progress, A Rake’s Progress and Marriage-a-la-Mode.

【推荐2】The Plastic Bottle Village is just a great idea that might finally help people protect the environment. It’s a village in Panama that is going to be made of used plastic bottles.
The village will include about 120 homes of different sizes. The design begins with building structures of steel(钢铁)，which are then filled with these bottles. Once this step is complete，and electrical lines are put inside，the plastic walls are covered by concrete(混凝土)—both inside and outside. So no one will actually be able to tell that the walls are made of plastic. Besides，the material will keep the house 17 ℃ cooler than the temperature outside，which is the biggest advantage to people living inside.
The village is the work of Robert Bezeau with the purpose of setting up some environmental projects. Having started a recycling program in 2012，during which a number of plastic bottles were collected，he started to think how they could be put to use. Soon enough，he decided to use them to build houses.
Over 10，000 plastic bottles were used to build the first house，which was completed late last year. The bottles were gained from the same recycling project that Robert had set up. The next home is expected to be bigger，and will need more bottles. The special homes will be sold on request for anywhere between $149，000 and $300，000. The village will also feature its living environment，such as gardens，mini－parks，and more.
22，000 plastic bottles are thrown away around the world per second. While all these bottles clearly cannot be reused into homes，the project hopes to raise the attention of the waste. The village will also create an education center that will teach people from the world how to reuse plastic bottles as building materials.
1. What is so special about the homes in the village?| A．They can stop people from being cold. |
| B．They are built out of plastic bottles. |
| C．They are being built by famous artists. |

It seemed ridiculous. On a practical level, there’s no way I could afford to buy a house anytime soon. More importantly, I wouldn’t want to. I’m not sure where I’ll be living in two years, or what kind of job I’ll have. And I don’t think I’ll be ready to settle down and stay in one place.
So this is probably the generation gap that divides my friends and me from our parents. When our parents were our age, they’d gotten their education, chosen a career, and were starting to settle into responsible adult lives.
My friends and I – “Generation Y” – still aren’t sure what we want to do with our lives. Whatever we end up doing, we want to make sure we’re happy doing it. We’d rather take risks first, try out different jobs, and move from one city to another until we find our favorite place. We’d rather spend our money on travel than put it in a savings account.
This casual attitude towards responsibility has caused some critics to call my generation “arrogant”, “impatient”, and “overprotected”. Some of these complaints have a point. As children we were encouraged to succeed in school, but also to have fun. We grew up in a world full of technological innovation: cellphones, the Internet, instant messaging, and video games.
Our parents looked to rise vertically（垂直的）– starting at the bottom of the ladder and slowly making their way to the top, on the same track, often for the same company. That doesn’t apply to my generation.
Because of that, it may take us longer than our parents to arrive at responsible, stable adulthood. But that’s not necessarily a bad thing. In our desire to find satisfaction, we will work harder, struggle for ways to keep life interesting, and gain a broader set of experiences and knowledge than our parents’ generation did.

【推荐1】I am a perfectionist. I always try to do as much research as possible for role. For Taxi Driver I did actually drive a cab for a few weeks. It probably wasn’t necessary, but it was something I wanted to do.
I’ve realized how important it is to appreciate the things your parents leave behind. My father, Robert DeNiro Snr, died in 1993. Since then, I’ve kept his studio intact, just the way he left it. I thought about getting rid of it, but my family and I gathered there after his death and realized the reality is different to seeing it in pictures, so it stayed.
There is much more opportunity now than when I was starting out. There really was only TV and films made in California. Now the Internet has created so many more opportunities for actors.
I learned a lot about being a father from my father. I knew he loved me. It was important for me to know that, so I know it’s important for my kids to know it, too. I give my kids space, but we do spend a lot of time together. I guess I can be firm when necessary. I have four grandchildren and six children so I know what I’m talking about.
I understand why people use social media, but I don’t. No way! I don’t watch much TV or go to the movies either. To me, they’re just another distraction. And I have enough of those to worry about without all that staff as well.
Fame is not an issue for me these days. When I was younger, I found the attention difficult to deal with, but I’m mostly OK with it now. I go around quite freely and people may say “hello” or want a photo and that’s fine for me.

【推荐2】What exactly is intelligence? There aren’t any easy answers. Despite the progress that has been made in genetics and psychology, human intelligence has remained one of the most controversial areas of modern science, until now, that is, for the discovery of a gene linked to intelligence has made the experts think again.
Robert Plomin of the Institute of Psychiatry in London and his colleagues in the US have been looking into genetic make-up. From their research, they have discovered that a slightly different gene is more common in those with a high IQ. Plomin analyzed DNA from two groups of 51 children aged between 6 and 15. What he found was that the first group had an IQ of 136, putting them in the top 5% of the population, while the other group had an average IQ of 103. An analysis of their genes showed that 32% of children in the higher group had the gene in question, while only 16% in the second group did. However, there is a lot more research to be done, and Plomin himself is cautious at this early stage. He suggests that there are probably many genes that contribute to intelligence, rather than just one.
Several studies have shown a strong link between IQ and career success, although some psychologists remain unconvinced about this. Professor Michael Rowe, who has written a book called Genius Explained, is one of these. “The people with the highest IQs are not usually the ones who do best in their careers.”
Many psychologists now believe that when it comes to intelligence, IQ isn’t everything. Many alternative views have been put forward recently. One example is the idea of multiple intelligences, which was developed in the 1980s by Harvard psychologist Howard Gardner. This offers a much broader view than the IQ theory, including creativity and communication skills as relevant factors in intelligence.
Tony Buzan, brain expert and author of Master your Memory, is enthusiastic about this belief, arguing that true geniuses do indeed appear to combine high levels of each type of intelligence. He lists Alexander the Great, Pablo Picasso and Albert Einstein as examples. At the same time, Buzan believes that everyone can develop their intelligence, only if they take the trouble to exercise their brain. Perhaps there’s hope for us all!

【推荐3】Frightful had not been quite two weeks old when she first saw Sam Gribley. Small as she was, she had attacked him as he carried her to the ground. "I'm going to call you Frightful,'' he had said. Then he carried her to a tree. This was Sam's home.
He fed her four and five times a day. Before long, Frightful thought of him as her mother. He cared for her like a peregrine falcon （游隼） mother would.
When she was older, Sam made a perch （栖木）for her and placed her on it. He taught her to fly to his hand. When she was full-grown, he took her hunting with him. At night and on winter days, she perched on his bedstead and warmed herself by the fireplace. On summer days, she would sit on her perch outside and watch the birds and busy Sam. Patiently she waited for him to take her hunting. It was her greatest pleasure. She loved the sky and the winds.
Frightful was an excellent hunter who rarely missed. The food was shared. Their lives depended on each other.
Frightful wanted to fly but she could not see. Blindfolded, she had traveled with two strange men for several days.
One of them had taken her from the perch beside the tree. She looked at him before he covered her head. She must find Sam again now.
Sam had begged the man not to take her away, but he had pushed Sam aside and earned her. A door had closed, and she was inside a truck. The motor was moving. A falcon bell tinkled （叮当作响） nearby. A sharp-shinned hawk （条纹鹰）had shifted his feet. A prairie falcon called out a single note. They, like herself, were sensing the direction of the moving car.
Several feedings later, the second man put Frightful on a perch in a forest. The prairie falcon and sharp-shinned hawk were there, too. Although they would readily attack her, she was not afraid of them. Frightful was a peregrine falcon. She was faster than any other bird. Her long pointed wings, wide shoulders, and strong body were sculpted by the wind, the open sky, and the nature of her ancestral birds.
