Scientific research gives new explanations to a very old relationship.
Dog Sense: How the New Science of Dog Behaviour Can Make You a Better Friend to Your Pet. By John Bradshaw. Basic Books; 324 pages; $25.99. Buy from Amazon.com, Amazon.co.uk
Dogs seem to have been our beloved companions since there was written history. It is hard to be precise(精确地) about when the friendship began, but a reasonable guess is that it has been going strong for more than 20,000 years. For John Bradshaw, a biologist who founded the anthrozoology department(the place known as human-non-human-animal studies) at the University of Bristol, having some idea about how dogs got to be dogs is the first step towards gaining a better understanding of human-dog relationship. It is generally accepted that dogs were raised by human beings from wolves. However, Bradshaw’s research refuted the wrong ideas about the close relationship of dogs to wolves and the mistakes that this has led to, especially in the training of dogs over the past century or so.
Dogs are not like nicely brought-up wolves, says the author, nor are they much like people despite their excellent ability to enter our lives and our hearts. However, dogs have a distinguish talent: they experience and react to the world through their extraordinary sense of smell: their sensitivity to smells is between 10,000 and 100,000 times greater than ours. And their trainability allow dogs to perform almost unimaginable tasks, such as smelling the early stages of a cancer long before a normal medical diagnosis(诊断) would discover it.
The latest scientific research can help dogs and their owners have happier, healthier relationships by encouraging people to understand dogs better. But Mr. Bradshaw is also fearful. In particular, he fears the incestuous(近亲繁殖)narrowing of the gene pool that modern breeders have brought about. He also worries that the increasing urbanization of society and the pressures on couples to work long hours are putting dogs under huge stress.
“Dog Sense” is neither a report nor a description of the joys of dog-ownership. At times its use of research data can be slightly difficult to understand. But this is a wonderfully informative, instructive book that will do good to every dog whose owner reads it.

I love slipping into a comfortable chair for a long read—as I relax into the chair, I also relax into the author’s words, stories, and ideas. The physical book is so elegant that it disappears into the background, and what remains is the author’s world.
Today, we AMAZON are excited to announce Mindle, a wireless, portable reading device with instant access to more than 90,000 books, magazines, and newspapers.
We’ve been working on Mindle for more than three years. Our top design objective was for Mindle to disappear in your hands — to get out of the way — so you can enjoy your reading. We also wanted to go beyond the physical book. Mindle is wireless, so whether you’re lying in bed or riding a train, you can think of a book, and have it in less than 60 seconds. No computer is needed — you do your reading directly from the device.
We chose the same wireless technology used in advanced mobile phones. But unlike mobile phones, there are no monthly wireless bills, no service or data plans, and no yearly contracts. There is no software to install. We want you to get lost in your reading and not in the technology.
Mindle uses a new kind of display called electronic paper. Sharp and natural with no strong light, reading on Mindle is nothing like reading from a computer screen. Mindle weighs only 10.3 ounces — less than a paperback — but can carry two hundred books.
Enjoy learning about Mindle and many thanks!

【推荐1】Cats and many other animals can reflect light from their eyes. That’s why their eyes will usually shine brightly in photos taken in a less bright room.
Some species can see better in low light because they either hunt for food or need to look out for enemies throughout the night, or at the early morning and late afternoon.
In fact, domesticated (家养的) cats can see in conditions that are only 16% as bright as what people require. Cats achieve this because their pupils (瞳孔) are special. Pupils operate like windows, with bigger ones letting more light into the eye. And a cat’s pupils can become up to 50% larger than human pupils in weak light.
They also have a higher number of a specific type of light-sensing cell in the back of their eyes than we do. These cells, called rods, catch low-level light.
What’s more, cats have something people don’t: a tapetum lucidum, or eyeshine, which is behind the retina (视网膜), receiving light, changing the light to an electrical signal and sending this signal to the brain to form the image. A cat’s tapetum lucidum reflect light back to the retina, which gives the retina a second chance to absorb more light.
Unfortunately, animals with a tapetum lucidum give up some visual quality for their ability to see in weak light. That’s because bright light reflecting off he tapetum lucidum can make what they see a little more unclear. So, a cat needs to be seven times closer to an object to see it as sharply as a person would in a brightly lit place.
But don’t worry, I’m sure your cat would rather see clearly at night than read a book.

【推荐2】Taylor Swift, US singer-songwriter known for hits such as Shake It Off and You Belong With Me, has earned a new praise-she now has a new species of millipede (千足虫) named in her honor.
The millipede Nannaria swiftae joins 16 other new species described from the Appalachian Mountains of the United States. They have a valuable role, for they break down leaf litter and release their nutrients into the ecosystem. They live on the forest floor, where they feed on rotten leaves and other plant matter, and in fact, they are somewhat tricky to catch, because they tend to remain buried in the soil, sometimes staying completely beneath the surface.
Because of their presence in museum collections, scientists long suspected that the millipedes included many new species, but these specimens (标本) went undescribed for decades. To fix this, the researchers began a multi-year project to collect new specimens throughout the eastern US. They traveled to 17 US states, checking under leaf litter, rocks, and logs to find species so that they could sequence (测定序列) their DNA and scientifically describe them.
Looking at over 1, 800 specimens collected on their field study or taken from university and museum collections, the authors described 17 new species, including Nannaria marianae, which was named after Hennen’s wife. They discovered that the millipedes prefer to live in forested habitats near streams and are often found buried under the soil, exhibiting more mysterious behaviors than their relatives.
The lead author of the study, Derek Hennen, a fan of Taylor Swift says, “Her music helped me get through the highs and lows of graduate school, so naming a new millipede species after her is my way of saying thanks.”

【推荐3】When it comes to an ox, very similar to a bull, people will think of 2009, the Year of Ox. The Ox is a representative of the farming culture of China. In the farming economy, oxen are the major animals pulling plows (梨).
Of course, the good of oxen is not limited to plowing. In fact, they are seen as “boats on land” for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures.
In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who live in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar, and during their run they will take their oxen along, which indicates they regard the creature as human.
Because of the contribution of oxen in their lives, the Chinese people are very grateful to the animal. In addition, the use of oxen in ceremonies and the thanks people owe to oxen help to develop various traditional customs, which becomes an important part of the folk culture of the Chinese nation.
1. The second paragraph focuses on ______.A.the qualities of oxen | B.creatures for pulling plows |
C.treasures of the folk culture | D.tools in the farming economy |
A.Oxen are no more important today than in the past |

【推荐1】Global waming is the increase of the earth’ s average surface temperature due to the effect of greenhouse gases, for example, carbon dioxide, which traps heat that would otherwise escape from the earth. After the trees are cut down and more greenhouse gases are released, the “blanket’around the earth called the ozone layer(臭氧层), will get thicker. This catches more heat and makes the earth hotter. Luckily, there are many things that every citizen of the earth can do to help reduce the effects of global warming, and it is never too late or too early for children to take action.
The children should learn what a carbon footprint is. A carbon footprint is the amount of carbonand greenhouse gases people make as they lead the daily life and go about the normal activities. In other words, the carbon footprint is a measure of the environmental impact(冲击)the life has. To live an environmentally friendly life that doesn’t contribute to global warming, people want to have the smallest carbon footprint possible.
Almost everything people do contributes to global warming and is related to fossil fuel consumption. These can be direct uses of fossil fuels, like riding in a gasoline-powered car, or indirect contributions to greenhouse gases, such as eating fruits or vegetables that have to be shipped from far away to reach their tables.
If a child wants to make a contribution to reducing global warming, he should ridc a bicycle tothe near park, school, his friend’s house, or anywhere else instead of taking the car. Or he may try to walk or jog, which is also helpful. In addition, although trains and buses often run on fossil fuels, on average, each person uses less energy and produces less polution to run. Next time if children with their parents have to get around town or it’s too far to walk or bike, take the bus or other public transportation instead of asking for a ride.

【推荐2】While there are a few ways to make use of your old smartphone, one of the better ways is to convert into a dash cam(行车记录仪)that you can use on your bicycle. With the camera, you can record your rides, which is especially helpful if you are involved in a crash with another vehicle.
To use your smartphone as a dash cam on your bike, you will need to make sure it is properly secured to your bike. To do this correctly, you must take two strips of heavy-duty Velcro (a kind of cloth used as fastening) along with two pipe Clamps(管夹)and a flat corner brace(角撑)to properly attach it. You will start by attaching the comer brace to your smartphone.
Next, attach a Velcro strip to your phoned back. You will put the second strip on the end of the brace comer and cut any extra Velcro off and away from the brace. By using heavy-duty Velcro, you shouldn’t have to worry about the camera brace must be attached to the bicycle directly.
Take two pipe clamps so you can attach the part of the corner brace so the phone can be held up and used. The pipe clamps must be positioned near the center of the handlebar, which will enable you to get a better picture when videotaping.
To run a dash camp app on your old phone, you will just need to download a dash cam app onto the old phone. You will then just start the app at any time you head out on the road. There is always the chance of flaws, but you will be giving yourself a way to protect yourself in a friendly, eco-fiendly manner that is much less expensive than purchasing a dash cam.

【推荐3】We all know that drinking too much is bad for us, but what about moderate (适度的) drinking?
We’ve known about the association between moderate drinking and good health for quite some time. Researchers have identified that people who drink a moderate amount are at a lower risk of things like heart disease and obesity than both people who drink a lot and people who never drink. It’s fairly well-established that,if you look at society at large,people who drink a moderate amount are the healthiest in a number of ways.
The problem is that moderate drinking isn’t an isolated (孤立的) behaviour .You can’t easily separate moderate drinking from the people who drink moderately, which means that you can’t easily identify whether it’s actually the alcohol that’s improving people’s health or something more complex.
The issue is pretty obvious when you look at the people who drink moderately in all of these studies.They tend to be wealthier,more educated,smoke less and in general are better off than both people who drink a lot and those who never drink. People who don’t drink alcohol are also different in a lot of ways, mostly bad — for example, illness, poverty, and previous alcoholism.
Recent studies in Israel and New Zealand show that there probably aren’t any significant health benefits to moderate drinking. Once you get rid of the effects of society, even a small amount of drink is associated with worse health.
It seems that moderate drinking probably isn’t good for our health after all. While there may be some minor heart health benefits, alcohol is addictive and causes damage to many other organs.
I’m going to keep drinking, but not for my health. Wine is delicious and beer is just wonderful. Drink for the taste,drink to socialise, but don’t drink because you think it’s going to cure your depression or heal your heart. But if possible, try to drink less.

【推荐1】John H. Johnson was born in a black family in Arkansas City in 1918. His father died in an accident when John was six. He was reaching high school age, but his hometown offered no high school for blacks.
Luckily, he had strong-willed (意志坚强的), caring mother. John remembers that his mother told him many times, “Son, you can be anything you really want to be if you just believe. She told him not to be dependent on (依靠) others, including his mother. “You have to earn success,” said she. “All the people who work hard don’t succeed, but the only people who do succeed are those who work hard.”
These words came from a woman less than a third grade education. She also knew that believing and hard work don’t mean everything. So she worked hard as a cook for two years to save enough to take her son—then 15—to Chicago.
Chicago in1933 was not the promised land (乐土、希望之地) that black southerners were looking for, John’s mother and stepfather could not find work. But there John could go to school, and there he learned the power of words—as editor of the newspaper and yearbook of Du Stable High School. His wish was to publish a magazine for blacks.
While others discouraged (阻止、使气馁) him, John’s mother offered him more words to live by: “Nothing beats a failure but a try.” She also let him pawn (典当) her furniture (家具) to get the $500 he needed to start the Negro magazine.
It is natural the difficulties and failures followed John closely until he became very successful. He always keeps his mother’s words in mind. “Son, failure is not in your vocabulary.”
Now John H. Johnson is one of the 400 richest people in America—worth $150 million.

【推荐3】Everyday, 340 million people speak it. One billion people are learning it and it is said that by 2050, half of the world's population will be using it. What are we talking about? That global language-English.
The English language started in Britain in the 5th century. It is a mixed language. It was built up when German, Scandinavian and French invaders settled in England and created a common language for communication.
Today it is the official language of the UK, the USA, Australia, New Zealand, Canada, South Africa and Ireland as well as many islands in the Caribbean. Many other countries and regions use it for politics and business, for example, India, Pakistan, Nigeria and the Philippines. English is also one of the official languages of Hong Kong.
But global advertising and pop music mean that in most countries, you will see or hear some English. Thanks to McDonalds, we all know about “burgers”, “fries” and “milkshakes”. Songs by Madonna, Britney Spears and Celine Dion are in English. We can sing along, even if we do not understand what we are singing!
English is a messy language. Every year, dictionaries include new words that talk about popular culture, for example, computer-related words such as “blogging”, “download” and “chat room”. Also included are words that teenagers use. Who does not know “cool”, “OK” and “hello”?
Other languages also influence English. Many English words come from French. Words like “cafe” and expressions like “c'est la vie” (that is life) are all part of the English language. On the other hand, the French language includes English words like “le weekend” and “le camping”. German words are also part of English. Words like “kindergarten” come from the German language.
Recently, British people have become interested in “yoga”. But the word comes from an ancient Hindu language in India.
