It’s easy to think that the globe’s vast oceans would be effective barriers to the movement of land animals. An elephant can’t swim across the Pacific, after all. But it turns out that plenty of plants and animals have unintentionally floated across oceans from one continent to another. Now comes evidence that tiny, trapdoor spiders (蜘蛛) made such a journey millions of years ago.
Moggridgea rainbowi spiders can be found on Kangaroo Island, which sits off the south coast of Australia. These spiders build a silk-lined hole in the ground, notes Sophie Harrison, a biologist in Australia. The hole and trapdoor provide these spiders with shelter and protection. It also provides them an out-of-sight spot from which to wait for approaching creatures.
There is evidence, though, that the ancestors of them might have traveled millions of meters to get to Australia from Africa. That isn’t as unlikely as it might at first seem. Australia used to be connected to other continents, long ago, as part of a supercontinent called Gondwana. And humans have been known to transport species all over the planet. But there’s a third option. The spiders might have rafted (乘筏) long distances across the sea.
To figure out which story was most likely true, Harrison and her colleagues looked at the spider’s genes. They looked at the genes in seven Moggridgea rainbowi spiders from Kangaroo, and five species of Moggridgea spiders from South Africa. The Australian and African spiders split off from a common ancestor some 2 million to 16 million years ago, the genes showed.
If a large swatch of land washes into the sea, filled with arachnids (蛛形纲动物), the spiders may be able to hide themselves throughout the journey. Plus, they can “hold their breath” and survive on stored oxygen during periods of temporary flooding, the researchers note.

Besides, cats are not known for acts of selflessness (无私). But maybe we’re wrong about them. Don’t believe it? Then meet Pippa, a very unusual cat.
The black-and-white cat was left in a box outside a shop and taken by the British RSPCA to the Jansa family in Whitstable, Kent. They really loved her character (性格) and decided to adopt (收养) it，but they never guessed she’d become a lifesaver.
Eight-year-old Mia Jansa had diabetes and had become good at testing her blood during the day, as well as having something to eat or drink to bring her blood sugar levels back. But the danger was at night. Mia could easily experience hypoglycemic (低血糖症的) situations when she was asleep, which could cause even death.
Soon after she was adopted, Pippa went into Mia’s bedroom in the middle of the night and woke her up. When the child tested her blood sugar levels, she found they were dangerously low. Ever since, Pippa always visits Mia at night. If she can’t get her to wake up, she raises the alarm.
“Pippa does this of her own accord,” says Mia’s mother Laura. “We don’t make a request for caring because we don’t want to encourage wrong alarms. She gets plenty of hugs. It gives me peace of mind and I know someone else is keeping an eye on Mia.”
Now the family is so happy that they’ve chosen to adopt it in the first place.

【推荐2】A recent study suggests there's nothing soft about pink, as it is revealed that the pinkest flamingos are the toughest. Published in the Journal Ethology, a recent study found that a pink color of feathers was a good indicator of how aggressive a bird was when feeding, as well as a sign of good health or a signal that the bird was ready to breed(繁育）.
For the study, researchers observed the behavior of flamingos in different feeding situations, ranging from small indoor spaces to large outdoor spaces, with or without a pool.
They found that compared to indoor birds competing for food from a bowl, the outdoor-raised flamingos spent twice as much as time searching for food, so they had less time to show aggressive behaviors. Interestingly, their findings also revealed that when the race for food turned hot, the birds most likely to appeal to arms were the pinkest, whether they were male or female.
“The color of flamingos comes from their food, more specifically, from the algae(藻类）that they absorb from water. So the more food they have, the pinker the birds are,” said Dr. Paul Rose, from the University of Exeter, in a statement. “Flamingos live in large groups with complex structures, in which color plays an important role.”
Flamingos don't have a breeding season. Instead, they breed when they are healthy enough to do so. Their health is indicated by the color of the feathers, which is pinker in their prime and paler when they weak. So, the signal that a bird is ready to breed is described as a pink flush in its feathers, which goes away when the bird parents a chick or already passes its best reproductive time.
A healthy pink flamingo will have more time and energy to be aggressive and dominant when feeding. When birds have to crowd together to get their food, they fight more and therefore spend less time feeding, leading to the fading color of flamingos that are already weak. “And this definitely is unfavorable for their reproduction,” Rose said.
The research provides a direction for zoos to feed their flamingos and keep them content and colorful. That is, ensure captive birds are fed in a wide space, as crowded conditions are more likely to result in fights. “Based on my observations, I suggested some changes. And the keepers were willing to try them out. As a result, we've got pinker, more relaxed flamingos," said Dr. Rose.

【推荐3】According to new research from the University of Cambridge in England, sheep are able to recognize human faces from photographs.
The farm animals, which are social and have large brains, were previously known to be able to recognize one another, as well as familiar humans. However, their ability to recognize human faces from photos alone is novel (新奇的).
The recent study, the results of which were published in the journal Royal Society: Open Science, shows the woolly creatures could be trained to recognize still images of human faces, including those of former President Barack Obama and actress Emma Watson.
First, the sheep were trained to get close to certain images by being given food rewards. Later, they were able to recognize the images for which they had been rewarded. The sheep could even recognize images of faces shown at an angle.
“Anyone who has spent time working with sheep will know that they are smart, individual animals who are able to recognize their handlers,” said Professor Jenny Morton, who led the Cambridge study. “We’ve shown with our study that sheep have advanced face-recognition abilities, comparable with those of humans and monkeys.”
Recognizing faces is one of the most important social skills for human beings, and some disorders of the brain, including Huntington’s disease, have a bad effect on this ability.
“Sheep are long-lived and have brains that are similar in size and complexity to those of some monkeys. That means they can be useful models to help us understand disorders of the brain, such as Huntington's disease, which develop over a long time and influence cognitive (认知的) abilities. Our study gives us another way to study how these abilities change.” Morton said.

【推荐1】Dying for an ice-cream? A hundred years ago, you might have done just that. Until they were illegal in 1926 for their role in spreading tuberculosis (肺结核), ices were commonly sold in glasses, which were rarely cleaned. Scoop A wonderful Ice Cream World, the first exhibition of the British Museum of Food in King’s Cross, London, has a tower of these unlikely killers from the wide collection of experts Robin and Caroline Weir, authors of Ices: The Definitive Guide.
Yet the sweet pleasures of ice-cream were very much worth the risk. In the 17th and 18th centuries, they were regarded as a food only belonging to the super-rich, and a symbol of social position. It’s said that about 1 litre of ice-cream cost ￡50. “You really had to love your guests,” says Robin. Little wonder, he adds, that businessmen tried their best to keep their trade secret: “If you knew how to make ice-cream, it was a meal ticket for life.”
What businessmen wanted to conceal was just how they made ice-cream: with a handful of ingredients (原料), some ice, salt and a bit of effort. “you can create thousands of different kinds of ice-cream, ”Robin says. Yet, for all that, boring old vanilla (香草) remains the most popular. Nine out of ten ice-creams sold were vanilla ice-cream, according to the Ice Cream Alliance.
Whatever kind of ice-cream you like, it is all too easy to overeat, an experience likely to end in the pain known as “brain freeze”. Luckily, the way to deal with it is very simple — place your tongue on the roof of your mouth to help warm the nerve.

To answer this question, we need to look back at the time of the Roman Empire. At this time Roman artists, scientists and writers influenced by Greek ideas were the world’s most advanced. They had become skilled observers of the natural world around them, and had become experts in studying animals, plants, the human body or the stars and planets. They wrote down their ideas about what they saw, and based their theories about the world on their observations.
During the fourth and fifth centuries the Roman Empire slowly broke down. Many of the Romans’ art and sculptures were destroyed and some manuscripts（原稿）were lost as well. But most importantly, some of the ancient attitudes were lost. A questioning approach to the world was replaced by an unquestioning one.
Why did this happen? One reason was to do with the influence of the Christian Church. Through the thousand years following the fall of the Roman Empire, the Church controlled many aspects of life including education and learning. The Church ran all the universities and thought that the aim of a university should be to teach old ideas more clearly, not to introduce new ones. The scholars in the universities were expected to study God and heaven from the Bible and ancient books, rather than the world around them.
Take medicine for example. The main textbook for doctors had been written by a Greek doctor called Galen more than a thousand years earlier. But when Roger Bacon, a thirteenth-century priest（牧师）, said that a new approach to medicine was needed --- doctors should do their own original research instead of reading writers from the past such as Galen-the Church put him in prison.
By the time of the fourteenth century, however, some parts of the Christian Church were becoming less strict about their ideas and there was a new state of mind among artists, doctors and scientist. People wanted to find out more about the world by studying it. This attitude of investigation had been common in classical scholars, and it was ‘reborn’ during the Renaissance.

【推荐3】To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. It was first used as a shade against the sun.
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C.
We know that the umbrella was also used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use; it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royal people or by those in high office.
In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrellas as protection against the rain were the ancient Romans.
During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in 16th century. And again it became a symbol of power and authority.
Umbrellas have not changed much in style during all this time, though they have become much lighter in weight.It wasn’t until the twentieth century that women’s umbrellas began to be made in a variety of colors.

No two homes will be the same. People will be able to buy “house kits” containing a basic house structure, with movable walls, doors and windows. They will put together the different parts to create the home they want.
Many jobs that we do today will disappear, others will still exist but will change and new jobs will be created. Skilled workers such as builders, gardeners and electricians won’t disappear because machines can’t replace them. Teachers will still exist because students need human contact. But they will be using modern technology in class more and students will be working more from home. The medical technology revolution and space travel will create new jobs which we can only imagine today.
Space holidays will develop in the future, but these holidays won’t be for everyone because they won’t be cheap. Short space trips will develop first, then space hotels will orbit the earth where it will be possible to have a longer vacation. By the end of the next century, there will be holiday centers on the moon with leisure facilities for families.
Paper won’t exist in the future. Instead, there will be e-paper which people will be able to use over and over again. This will develop in order to save natural resources. E-newspapers and e-magazines will replace traditional newspapers and magazines and we will download information and news articles from the Internet every day onto our reusable paper.
The laws of physics tell us that the earth is going to disappear sometime in the future. This isn’t going to happen tomorrow but scientists predict that it will happen in five billion years when our sun explodes (爆炸). We will have to explore the universe and find another home.

【推荐2】We all love to take photographs. It’s a simple way to capture a special moment, an amazing view, or just to show off your artistic skills. And it’s great to look back through your photo albums and share your memories with friends. This hasn’t really changed since the invention of photography in the 1830s. But one thing that has changed is the equipment we use.
For many years, we have used traditional cameras to take our pictures with. Our images were captured onto camera film which was then processed into negatives from which photos were printed – a long process.
But the biggest change has come with the development of digital technology. This has made taking photos quicker and easier. It’s enabled us to take a snap and review our pictures instantly. We’ve been able to beautify them, using software on our computer. And of course, we’ve been able to share them like never before – particularly on social media.
Of course, now we have the smartphone – a phone that is, well, smart because it can take photos and sometimes very good quality ones, and we can share them easily. So does that mean the traditional camera will eventually become out-dated? Figures from Japan show how the market is shrinking: shipments of traditional digital cameras from companies like Olympus, Canon and Nikon were down 39% year on year.
But Phil Hall, editor of Tech Radar magazine thinks there’s nothing to worry about. He said while people are replacing their digital cameras with smartphones, producers are looking at the more higher-end cameras, like mirrorless cameras.
Certainly, the growth of the smartphone means more and more of us are taking photos and it opens our eyes to the creative possibilities it can provide. But whatever camera viewfinder we end up looking through, it’s important to remember the basics of focusing, good lighting and framing and getting your subject to say “cheese”!

【推荐3】Choosing the Right Resolution (决定)
Millions of Americans began 2014 with the same resolution they started 2013 with, a goal of losing weight. However, setting weight loss as a goal is a mistake.
To reach our goal of losing weight — the output, we need to control what we eat — the input (输入). That is, we tend to care about the output but not to control the input. This is a bad way to construct goals. The alternative is to focus your resolution on the input. Instead of resolving to lose weight, try an actionable resolution: “I’ll stop having desert for lunch,” or “I’ll walk every day for 20 minutes.” Creating a goal that focuses on a well-specified input will likely be more effective than concentrating on the outcome.
Recently a new science behind incentives (激励), including in education, has been discussed. For example, researcher Roland Fryer wanted to see what works best in motivating children to do better in school. In some cases, he gave students incentives based on input, like reading certain books, while in others, the incentives were based on output, like results on exams. His main finding was that incentives increased achievement when based on input but had no effect on output. Fryer’s conclusion was that the intensives for inputs might be more effective because do not know how to do better on exam, aside from general rules like “study harder.” Reading certain books, on the other hand, is a well-set task over which they have much more control.
As long as you have direct control over your goal, you have a much higher chance of success. And it’s easier to start again if you fail, because you know exactly what you need to do.
If you want to cut down on your spending, a good goal would be making morning coffee at home instead of going to a cafe, for example. This is a well-specified action-based goal for which you can measure your success easily. Spending less money isn’t a goal because it’s too general. Similarly, if you want to spend more time with your family, don’t stop with this general wish. Think about an actionable habit that you could adopt and stick to, like a family movie night every Wednesday.
In the long run, these new goals could become a habit.

【推荐1】Missouri is a midwestern state lost in a never-ending sea of corn. However, somewhere hidden in these fields of corn lies one of the most impressive man-made lakes in the US, the Lake of the Ozarks. Built in the heart of Missouri, the lake was another destination on my 14-state road trip as I camped my way across America.
Surrounded by the beautiful Ozark Mountains from which it gets its name, the lake has become a mainstay in family weekend vacations since it was built in 1931. Known for natural beauty, the Ozarks remain a large tourist destination, bringing in over 5 million people each year. With choices ranging from basic camping to luxury resorts（高档度假胜地），the Ozarks have something to offer people from all backgrounds and budgets.
With more shoreline than the entire coast of California, the Lake of the Ozarks has become a favorite of boat and beach lovers alike. The huge 241-square-km lake is home to almost every watersport, ranging from something as simple as swimming to even the most extreme like parasailing or jet skiing. Although originally attracted to the campsites at the Ozarks, it was hard to resist（抵制） the call of the water and I soon found myself joining in on the fun.
Getting a respectable 4. 7 stars on Google by over a thousand reviewers, the lake has clearly held up its popular reputation. Although I did enjoy my one-person trip, I can strongly say that the Lake of the Ozarks is the most enjoyable when surrounded by friends or family. With so much to see and do, it can be overwhelming（应接不暇的）for a solo（个人的）traveler. Even with my packed three - day schedule, 1 still missed a majority of what this great location has to offer.

Mencap is a charity which is intended to fight against prejudice against those people who suffer from any kind of learning disability. Most of Mencap's work is campaigning. People with learning disabilities are disadvantaged because of prejudice and lack of funding for community care. Mencap raised awareness by working at local, national and European levels to deal with those issues that affect people with learning disabilities. It also provides services of education, housing and employment as well as support and advice for families and carers of sufferers.
EveryChild is a relatively new charity which was created in 1983. Every Child identifies the needs of a particular community and then sets up projects to make sure that children in these communities have basic rights such as healthcare. education, social services and community development. Every Child sets up the projects so that they are self running. The organization then moves on to new projects, leaving things in the hands of locals.
The RSPCA( Royal Society for the Prevention of Cruelty to Animals) is the first organization meant for the well-being of animals anywhere in the world. The SPCA was set up in London in 1824 .At that time it was considered strange that people should care about cruelty to animals. In 1840 Queen Victoria gave the organization permission to be called a royal society The RSPCA. These days there are almost two hundred branches in the UK.
The TBG(Tidy Britain Group) is an independent national charity fighting to improve the quality of the local environment. They aim to get everyone involved in doing their bit to keep Britain clean.
