Dogs are wonderful companions all their own, but they can also help change your life so that you're more accepting of new friendships. A new study studied how dogs' brains responded to the human voice and found that “the human brain responds to dog emotions the same way it responds to human emotions” and that the dog's brain does the same.

    Dogs are pack animals, so in terms of pet ownership, your dog will prefer to stay with you rather than somewhere alone. Think about how this concept applies to friendship. People today are getting more and more used to spending time on social networking, email, and text. While all methods of communication are good, there is nothing like seeing your friends and hearing their voice. With good friends, sometimes a look explains everything, and you can only get this when you're together hanging out in person.

    Let's face it, dogs never hide their feeling. They let you know what they enjoy doing most, whether it is chasing a ball, going for a walk, or getting a treat. For people, it's harder to be open with your emotions. But in order to truly find a friend, you'll need to let go of your fears and put trust into your friends. The reality is that you'll never make everyone you meet happy one-hundred percent of the time, so if your friends and family think you're great, put aside the need to be liked by everyone.

    Dogs wait for you to come home and are so happy to see you again that they practically do a happy dance when you walk through the door. Friends, on the other hand, are sometimes so busy that even hearing from a friend becomes an unwelcome interruption. Rather than avoid calls or emails, make a point to talk to friends on a regular basis.

    In an unmanned supermarket,a customer waits to pay.With the use of advanced digital payment technology, including biological recognition and in-depth learning,the man leaves in a minute.There's no cashier in the store.At a large university,students use a hand-scanning machine that authorizes their entry into the gym.Those people are using “smart machines” which identify people by their physical characteristics.These new devices use fingers,hands, faces,eyes and voices.Some machines may even use smells.This new technology,called biometrics,gets information from parts of the body.

    In the past,biometric machines were used mainly in government agencies or in prisons.But now that the cost of the technology is lower,these machines are starting to be used everywhere,from border services to schools.

    Some people,however,are concerned that these machines will mean the destruction of personal privacy.They worry that the machines will get personal information about them.“I know it seems like these machines are invading our privacy,but actually,biometric machines help to protect it,”says Jay Tarkett,who works at a company that develops the machines.“They can be used instead of passwords on a computer,for example.They can also identify criminals at airports.So,really,they help to promote public safety,and all the information stored is kept confidential by  the machine itself.”

    Some people don't like the idea of using fingerprints because they associate them with criminals,and feel like they are being accused of something.In addition,they don't work for some people,such as bricklayers,who wear down their fingerprints.Yet,face recognition does work well because the subject doesn't really have to do anything.To cash a check at a bank,for example,the customer has to do nothing more than look at a machine similar to an automatic teller.If the face matches the picture kept on fie,the customer gets the money with no problems.The need to carry identification with you from place to place,then,would all but cease.

    It has been found that the hand scan works well in the college gym.Before this machine was used,students at the college entered the gym using cards similar to credit cards.The problem was that students often lost or forgot their cards.With the hand-scanning machine,however,the problem was solved right away.

    But the machines are still new,and there can be problems.For example,voice recognition works on the phone, but it is not precise,and can be tricked.Another constraint（限制）we notice,with machines that use face recognition in particular,is that they can be fooled if people color their hair or gain a lot of weight.However,this particular problem may be solved by a new type of technology that scans a person's iris,the colored part of the eye.It can even identify the person from a few feet away,recognizing a customer as he or she approaches the ATM.

    With the rapid development of China's economy, more and more foreigners begin to learn Chinese because they are beginning to realize the importance and growing influence of China. Pupils in Warwickshire will soon be learning Mandarin after new links were forged(建立联系) with a region in China.

    Head teachers from the county spent a week in Shenzhen in South-east China, making links with schools and touring different education establishments.

    Schools that took part are now looking to introduce Mandarin lessons. Pupils from schools in Warwickshire and Shenzhen are starting to write and e-mail each other and plans are being made to share lessons over the Internet.

The trip was arranged by Warwickshire County Council and funded by the British Council as the first stage of development of a range of ties with the economically booming city.

    International development officer Judith Young said: “We are entering an exciting period of school relation between Warwickshire and Shenzhen. There is a real appetite for sharing ideas among the Chinese. We were able to see the differences and similarities between the education systems and there are many areas in which our schools, teachers and pupils will be able to benefit from a different cultural perspective(观点) and links with a country that is becoming very important on the world stage.

    Throughout the high profile(引人注目) visit led by our county education officer, Eric Wood, our group was made to feel very welcome and attracted a great deal of interest. Our visit to a primary school was featured as the main news item on television that night. A mark of how highly the visit was valued is that plans are being made for a return visit to Warwickshire of civic leaders, senior education officials and school principals.”

    Two thieves came to a house to steal something, they dug a hole in the wall of the house.

    There lived many mice in the house. The woman in the moonlight saw a mouse crawl (爬行) into the house. “Look! In comes one,” she said to the man in the house. He was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, “She found me when I was just in.” But the thief outside didn't believe him, so he said, “Let us two try to crawl into the house together.” At that time two mice happened to crawl into the house, too. The woman saw the mice and shouted, “In come two, catch them!” The two thieves were terribly frightened. The man in the house said, “You saw them come in but where are they? I will catch them tonight.” The two thieves started running away at once.

    The two thieves wanted to make it clear whether they had been found or not the night before. The next day they acted as men selling sweet potatoes and came before the house. The man and the woman were ploughing in their fields. The rein (缰绳) broke and the woman came home for a rope. She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn't wait for her any longer in the fields and he ran back from the fields to hurry her up. The woman showed the sweet potatoes to the man and said, “How they look like the two of last night.” The man said, “I asked you to fetch a rope, why don't you hurry for it?” The two thieves ran away very quickly without their sweet potatoes.

    “Has anyone seen Charge?” I asked, only half expecting a reply. The kids were running around the house, each doing their own thing, and my husband was watching the football game. Since she had only been out of sight for a few hours, I wasn't overly concerned. I thought she must be under one of the kids' beds, hiding from all the mess that was normal for a Sunday afternoon in our home.

    ①

    Charge was not good-looking, to put it kindly. It wasn't her fault; she was simply gifted with the worst appearance traits（特征）in her background.

    My husband had found Charge wandering along the freeway one day on his way home from work. She looked as though she hadn't eaten in weeks, so he stopped and fed her with bits of his leftover lunch. Not knowing what to do, he brought her home with the hope of finding her owners or at least a loving family that would take her. However, once she was in the house, the kids were determined not to let her go. After a day or two of begging, we unwillingly gave in and told them we could keep her.

    After observing her actions for days, I found she was extremely distrustful and afraid of everyone. In time, though, she came to love the kids and slept on their beds every night. I wondered if what she had experienced had conditioned her to be protective of those who were hurting. Every time the kids cried, Charge would run to them and gently offer her comforting paw（爪子）. Unlike our cat, who had recently given birth to five kittens, Charge would have been a great mother.

    ②

    When I was finally able to get everyone's attention at the dinner table, I asked again if anyone had seen Charge. After a unanimous（异口同声的）“No”, I decided to take a look around the neighborhood.

    ③

    “Charge!” I cried, because there she was in the closet! She looked up at me from inside the little cats' box as if to say,“ Shhh, I just got them to sleep!”

    We usually kept the closet door open a bit so our mamma cat could go in and feed her kittens, but she always left as soon as she finished nursing. Obviously, Charge knew they needed more mamma time and was more than willing to help out.

    ④

    The kids smiled upon seeing the dog with the kittens. My husband shook his head and said, “Only you, Charge. Only you!”

    Charge continued to mother the kittens until they were placed in their new homes. Charge may not have been an attractive dog, but she truly had her inner beauty.

A Colourful Puzzle

    People often wear clothing with colours that express something about themselves. A happy person might choose to wear a bright yellow shirt. A swimmer might wear a sea-blue dress.

    Animals appear in different colours too, but they don't get to pick what they wear every morning. Scientists have known for a long time about some of the ways animal colouring can be beneficial. They know that some animals' colours attract mates or show who is boss. Other animals' colours blend(融合) in with their environment; thus the animals cannot be seen by their enemies. Still, scientists do not fully understand why blue jays are blue or why rainforest frogs are golden. Now many scientists are working hard to figure out the puzzles of animal colours.

    Part of the answer can be found in an animal's habitat, the place where it lives. It turns out that many animals — especially birds, fish, and reptiles — can see more colours than humans can. These creatures notice colours that stand out in their habitat. For example, forests are mostly green, brown, and yellow. For an animal to be seen by others of its species, it would have to be a different colour than its background. That explains why you can find birds of many shades of blue living in forests.

    Another piece of the puzzle lies in what an animal eats. Birds often eat things that have chemicals in them called “carotenoids”(类葫萝卜素). These chemicals are what make tomatoes red and bell peppers bright orange or yellow. When birds eat these foods, the carotenoids affect the colour of their feathers. For example, a cardinal's bright red feathers will become lighter or darker depending on how many berries it has found to eat.

    Some animals do not have any colour at all — but they are not just white; they are transparent(透明的)! Transparent animals live mostly in the ocean. This amazing wonder of nature came about because the animals needed a way to escape their enemies. They are often slow, defenseless creatures that would have no way of fighting back if larger animals wanted to eat them. Because there are few places to hide in the ocean, these creatures have to hide in plain sight. A good example of this kind of transparent creature is the jellyfish. A jellyfish's body is almost all water, so it is very hard to see it floating in the ocean.

    Animals come in all kinds of colours. Their colours are caused by many different factors, and most animals will remain the same colour for their whole lives. Think how lucky we are to get to change our feathers every day!
