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.
小题1: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.

小题2: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.

小题3: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.

答案

小题1:C
小题2:B
小题3:A

解析

试题分析：本文主要讲述的就是把动物的骗术行为用在军事的研究方面。文章中讲述了具体的研究信息。
小题1:C 细节题。根据文章最后一段It could lead an enemy down a fake trail or make itself look more dangerous than it actually is.说明C项内容与之相符，故C正确。
小题2:B 细节题。根据第三段最后三行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说明the babblers并没有攻击robots，故B项说法是错误的。
小题3:A 主旨大意题。根据文章主题段第一段内容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.可知本文主要讲述的就是把动物的这种行为用在军事的研究方面，故A正确。
点评：本文主要讲述的就是把动物的骗术行为用在军事的研究方面。这篇文章要先看问题，再带着问题仔细阅读短文，理解了全文内容，很容易选出正确答案。阅读短文时，常常会遇到一些生词。这时，要沉着，冷静，细心思考。首先要把整段、整篇文章看完。通过对全篇短文的理解，就很有可能猜测出生词的大意。另外，还可以从含有生词句子的上下文，以及句子和段落之间的关系来判断、理解生词以求获得其真正含义。猜测生词的另一种方法是，根据构词法推测。遇到生词后，可从构词法角度分析判断生词。
