Deception (骗术）is something that people do all the time ,and it plays an important role in military (军事的)strategy. Now some researchers are trying to figure out how to get robots to do it, by looking at the behavior of squirrels and birds.
At Georgia Tech, a team led by Ronald Arkin , a professor at the School of interactive Computing, studied the literature on squirrels hiding their acorns (橡果）.Squirrels will hide their food m a certain place, but when they see other squirrels trying to steal from them, they attempt to fool the thieves by running to a fake location.
Ronald Arkin and his Ph. D. student Jaeeun Shim used that as a model for robot behavior. They programmed the robot into tricking a “predator (捕食者）” machine by doing what εi squirrel does： showing the enemy a false location for an important resource.
The team also looked at how other animals in this case，a species of bird called Arabian babbler~ drive off predators. A babbler will make an alarm call when they see a predator and other babblers will join the bird and make more calls. They then surround the predator, all the while flapping (拍打）wings and making noises. The babblers don’t ever actually fight the animal they want to drive off； they just make enough noises and flaps around enough so that it seems that attacking a babbler isn’t worth it
They found that the deception works when the group reaches a certain size—essentially, when enough birds arrive to convince the enemy that it’s best to back off . Davis modeled that behavior in software using a military scene and found that it worked even if the group didn’t have the firepower to confront the enemy directly.
The military is interested in this because a robot that can fool an opponent is a valuable tool. It could lead an enemy down a fake trail or make itself look more dangerous than it actually is.
Why does the military want to take advantage of squirrels’trick?

A．It can reduce the use of firepower to confront the enemy.

B．It can fool the enemy into believing it is more dangerous.

C．It can lead the enemy in a wrong direction to avoid losing resources.

D．It can scare the enemy away who wants to destroy the acorns.

Which of the following is NOT the way Arabian babblers drive off predators?

A．One bird makes an alarm call and other birds will join it

B．They fight the enemy bravely face to face.

C．They make noises and flaps around the predator.

D．They force the predator aware that it isn't worthwhile to attack.

What is the main idea of the passage?

A．Animals' behaviors are researched to be applied to the study of military robots.

B．Robots, fooling tricks are applied to the study of animals’behaviors.

C．Birds and squirrels are the animals that are good at deception.

D．Researchers are interested m animals’military-related behaviors.

UGG boots have been a winter-weather fashion for several years now, combining function, comfort, warmth and even some style. What many UGG-enthusiasts don’t know is that their boots are a breeding ground for bacteria and cause foot problems.
Doctors believe the boots, which are particularly popular among young teenage girls, are leading to a rise in the number of people suffering pains in their feet and knees.
Dr. Ian Drysdale，head of the British College of Osteopathic Medicine，believes because the foot does not get the proper support on the inside，it will lead to more ankle，knee，hip and back problems. “These boots are not designed for outside wear. Just because something becomes a trend or fashionable doesn’t mean it’s good or right，” he said, “The particular problem with this type of footwear is that it is unsupported. It’s a slipper. You wouldn’t normally expect to be doing outdoor activities from something that’s indoor. If you decide to wear your pajamas outside all. the time, someone will come up and say it’s not a good idea. ” Dr. Drysdale explained that the feet issues become a particular problem among young teenage girls，whose bones are “ plastic ” and developing when they are growing. “ If that structure is developing in an inappropriate way,” he said, “then the ultimate structure will be deformed ”
Mike 0，NeiU, a consultant surgeon, said, “As the foot slides around, you get wear and tear (磨损）on the joints on the inside of the foot The ankle is m the wrong position, the thigh bone also changes position, and you get an abnormal movement in the pelvis, which leads to back problems. ”
UGG AustraUa₉ who makes the designer version of the boots, told The Daily Mirror that their boots are “comfort” rather than “performance” footwear and consumers should be aware of “knockoffs”（仿制品)which lack reinforced heels in their boots.

The farmer received a steady stream of refusals at the interview for a farmhand
Finally, a short, thin man approached the farmer. “Are you a good farmhand?” the farmer asked him.

[1]All people have dreams and they obey the rule that if you can dream it, you can achieve it! Here are four goals for people to reach a perfect life in their future.
[2]The first goal common to all of us in health and energy. We all want to be healthy and fit, to have high levels of energy and to live free of pain and illness. Today, with the incredible advances in medical science, the quality of our health and fitness, and our lifespan, is largely determined by design, not by chance. People with excellent health habits are far healthier, have more energy, and live longer and better than people who have poor health habits. Remember that health is not everything, but without health everything is nothing!
[3]The second goal that we all have in common is to enjoy excellent relationships – intimate, personal or social – with the people we like and respect, and who is turn. Fully 85% of your happiness will be determined by the quality of your relationships at each stage, and in each area, of your life. How well you get along with people, and how much they , have more impact on the quality of your life than perhaps any other factor.
The third common goal is to do work that we enjoy, to do it well, and to be well paid for it. You want to be able to get and keep the job you want, to get paid more and promoted faster. You want to earn the very most that is possible for you at each stage of your career, whatever you do.
The fourth goal we all have in common is to achieve financial independence. You want to reach the point in life where you have enough money so that you never have any financial worries. You want to be completely free of them. You want to be able to order dinner in a restaurant without referring to the price listing to determine what you want to eat.
