Most people agree that honesty is a goodthing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive.

    Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.

    Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves.They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.

    Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests（鸟巢）. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them.

    Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again.

    Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cryvery softly when they find food. That way, other chimps don't hear them,  and they don't need to share their food.

    As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her,either.

    Whether in the home or the workplace, social robots are going to become a lot more common in the next few years. Social robots are about to bring technology to the everyday world in a more humanized way, said Cynthia Breazeal, chief scientist at the robot company Jibo.

    While household robots today do the normal housework, social robots will be much more like companions(同伴) than mere tools. For example, these robots will be able to distinguish when someone is happy or sad. This allows them to respond more appropriately to the user.

    The Jibo robot, arranged to ship later this year, is designed to be a personalized assistant. You can talk to the robot, ask it questions, and make requests for it to perform different tasks. The robot doesn't just deliver general answers to questions; it responds based on what it learns about each individual in the household. It can do things such as reminding an elderly family member to take medicine or taking family photos.

    Social robots are not just finding their way into the home. They have potential applications in everything from education to health care and are already finding their way into some of these spaces.

    Fellow Robots is one company bringing social robots to the market. The company's “Oshbot” robot is built to assist customers in a store, which can help the customers find items and help guide them to the product's location in the store. It can also speak different languages and make recommendations for different items based on what the customer is shopping for.

    The more interaction the robot has with humans, the more it learns. But Oshbot, like other social robots, is not intended to replace workers, but to work alongside other employees. “We have technologies to train social robots to do things not for us, but with us,” said Breazeal.

    You're in a department store and you see a couple of attractive young women looking at a sweater．You listen to their conversation：

    “I can't believe it－Lorenzo Bertolla! They are almost impossible to find．Isn't it beautiful? And it's a lot cheaper than the one Sara bought in Rome．”

    They leave and you go over to see this incredible sweater．It's nice and the price is right．You've never heard of Lorenzo Bertolla, but those girls looked really stylish．They must know．So, you buy it．You never realize that those young women are employees of an advertising agency．They are actually paid to go from store to store, talking loudly about Lorenzo Bertolla clothes．

    Every day we notice what people are wearing, driving and eating．If the person looks cool, the product seems cool, too．This is the secret of undercover marketing．Companies from Ford to Nike are starting to use it．

    Undercover marketing is important because it reaches people that don't pay attention to traditional advertising．This is particularly true of the MTV generation－consumers between the age of 18 and （3）It's a golden group．They have a lot of money to spend, but they don't trust ads．

    So advertising agencies hire young actors to “perform” in bars and other places where young adults go．Some people might call this practice misleading, but marketing executive Jonathan Ressler calls it creative．“Look at traditional advertising．Its effectiveness is decreasing．”It is true, because everyone knows an ad is trying to persuade you to buy something．However, you don't know when a conversation you overhear is just a performance．

    Drunk driving, a major concern currently, is not a funny thing, {#blank#}1{#/blank#}has killed many people and ruined the lives of many others. At present, traffic accidents become "the world's first harm".

    Two months ago, after {#blank#}2{#/blank#}(drink) a lot of alcohol, my friend's uncle drove his car home. He was{#blank#}3{#/blank#}(heavy) drunk, but he still drove home by {#blank#}4{#/blank#}. On the road near his home, an old lady was going across the road, {#blank#}5{#/blank#} his uncle didn't notice her and he was still moving on under the influence of alcohol. And the old lady didn't see his uncle, either. In the end, the lady died.

    {#blank#}6{#/blank#} it not been for his uncle's drunkenness, the terrible accident would not have happened. If the lady hadn't died, she {#blank#}7{#/blank#} live a happy life with her daughters and sons. And his uncle's home was also destroyed by his uncle. Therefore, two {#blank#}8{#/blank#}(family) were destroyed.

    I wish more people {#blank#}9{#/blank#}(can) realize the seriousness of drunk driving and obey the traffic regulations faithfully. Always remember: refuse {#blank#}10{#/blank#}(drink) and drive, and give a safe world to you and me!

    We think that life in Chinese high school is an adventure in which we have to survive mountains of homework and all kinds of exams. Yet would it be{#blank#}1{#/blank#}(surprise) if I tell you that high school life in the US is almost as stressful and demanding as it is in China?

    In US high school, everything{#blank#}2{#/blank#}(record) into your studying document, including your grades on quizzes, tests and final examinations. Failing{#blank#}3{#/blank#}(turn) in your homework on time will directly affect your grade for a certain course. Perhaps contrary to{#blank#}4{#/blank#}we used to think of the US high school students, they pay more attention to their{#blank#}5{#/blank#}(academy) performance to try to get into a distinguished university.{#blank#}6{#/blank#}, they'll be disappointed after graduation from high school.

    Like university students, US high school students have the{#blank#}7{#/blank#}(free) to choose the courses that most interest{#blank#}8{#/blank#}(they). Even a ninth grader can sit{#blank#}9{#/blank#}the same classroom as twelfth graders. But this also means he or she has to work very hard, because the teacher will not treat him or her differently just because he or she is a few years{#blank#}10{#/blank#}(young).

    Do you worry about entering senior high school? Everything, from study to environment, has changed. Can you adapt yourself to it?

    You're not alone. Remember that everybody else in your year is in the same boat. You may not notice it, but they're just as nervous as you are.

    Moving to senior high school is a chance, not a problem. Things are different, and all you need to do is to be polite and learn the new rules.

    The teachers will help. If you don't know what to do or are worried about something, then ask for help. Teachers are probably the best people to turn to, because they have experience in helping new students. Pay attention to what your teachers say.

    Everything changes. There are lots of differences between junior high school and senior high school. You will have your lessons with different teachers in different rooms. You will have homework for different subjects on different days, so make sure you get organized. Make sure you know which rooms your classes are in and which days you have your different subjects on.

Other points:

    If you've got an older brother or sister at the school, then ask them for advice.

    Be yourself! It sounds simple, but things will become better if you just act naturally.

    Having early nights makes a difference. You'll also find it easier to get up in the morning!
