The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect’s flight direction and pass on the information its eyes or other organs catch through the equipment set in its body， the official said.
It is thus designed that a tiny controlling chip will be equipped in an insect’s body when it is in chrysalis(蛹). As the insect grows， the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won’t influence the insect， sound growth or the functions of internal organs.
The terminal target of the project is to set up a global system， in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters.
Years ago， Defense Advanced Research Projects Agency of US DOD(国防部) spent $3,000,000 carrying out a plan for training bees to detect landmines. But， no new progress has so far been made.
“According to the scientists， there is still enormous difficulty in technology in turning it into reality， such as the insects reproduction(繁殖)， their adaptation to the surroundings and temperature and so on. However， this project is really challenging. If successful， it is equal to making countless small drone(无人机)，”said the official of DOD.

This view of bilingualism is different from the understanding of bilingualism through much of the 20th century．Researchers, educators and policy makers long considered a second language to be an interruption that prevented a child"s school work and ability to think and understand things．They were not wrong about the interruption: there is ample evidence that in a bilingual s brain both language systems are active even when he is using only one language, thus creating situations in which one system disturbs the other．But this interruption, researchers are finding out, isn"t so much a disturbance．It forces the brain to solve inside conflict, giving the mind a workout that strengthens its thinking muscles．
The key difference between bilinguals and monolinguals may be more basic: a heightened ability to monitor the environment．"Bilinguals have to switch languages quite often—you may talk to your father in one language and to your mother in another language," says Albert Costa, a researcher at the University of Pompea Fabra in Spain．
"It requires keeping track of changes around you in the same way that we monitor our surroundings when driving．" In a study comparing German-Italian bilinguals with Italian monolinguals on monitoring tasks, Mr．Costa and his colleagues found that the bilingual subjects not only performed better, but they also did so with less activity in parts of the brain involved in monitoring, showing that they did better in it．
小题1:From the passage we can learn that experts used to believe that ______．
| A．interruption forced a bilingual"s brain to strengthen its thinking ability |
| B．a second language stopped children"s studying as well as mental development |
| C．using two languages annoyed the children who have trouble in learning skills |
| D．language systems were busy in a bilingual"s brain when he was using languages |
| A．change | B．use | C．speak | D．study |
| A．Cautious． | B．Doubtful． | C．Concerned． | D．Favourable． |
| A．How Bilinguals Use Languages |
| B．What Bilingualism Is Really about |
| C．Why Bilinguals Are More Intelligent |
| D．When People Learn a Second Language |
A college dropout and self-taught engineer, Kamen already held over 100 patents for his inventions when he developed the one he hoped would revolutionize short-distance travel．While still in college, Kamen started developing the medical devices （设备） that made his name．Later, he changed focus to the challenges faced by wheelchair users．His robotic wheelchair known as IBOT could climb stairs．This robot ended up paving the way for the Segway．
Before showing his most recent invention, Kamen had kept it a top secret for months．When it turned out to be little more than a motor scooter, many publicly expressed their disappointment．On closer examination, however, even his critics（批评家） had to admit that the vehicle was an engineering achievement．It answered the prayers of anyone who is worn out when walking downtown．Not everyone welcomed the Segway"s arrival, though．Some complained it was too expensive, while others said it would further weaken the average American " s fitness．A Japanese inventor even accused Kamen of stealing the idea for the Segway from him．
Despite the controversy, the U．S．postal service began using Kamen"s invention a month after its appearance, and a factory was built with plans to produce about 40,000 Segways every month．The argument is still on whether the Segway will be remembered as the greatest invention since the light bulb, or just another forgettable electronic device．Anyway, trips to the local supermarket will never be the same again．
小题1:Which statement best describes the critics" reaction to the Segway?
| A．Nothing but an electrical device． |
| B．A disappointing engineering mistake． |
| C．An expensive and disappointing invention． |
| D．Disappointing, but still a successful device． |
| A．One person at a time can ride on it． |
| B．It has two wheels with a single axle． |
| C．It is powered by electricity and can go up to 12mph． |
| D．Riders increase the speed by moving the handlebars |
| A．high cost | B．danger to traffic |
| C．being difficult to use | D．contribution to laziness |
| A．hopes for a larger model of it |
| B．no plans to do anything more with it |
| C．some discussions on the unforgettable device |
| D．plans to make tens of thousands of them a month |
DISCOVER magazine once reported on a curious event in the woods : a group of monkeys applied mud (泥) to their faces in order to keep away insects , but when they were done they seemed to have lost their ability to recognize each other ---two monkeys that were supposed to be friends even started fighting.
“Faces are really important to how monkeys and apes (猿)can tell one another apart,” explained Michael Alfaro, a biologist at University of California, Los Angeles (UCLA), to the New York -based International Science Times . This is quite different from many other animals , which depend heavily on smells.
Since faces play such a crucial part in the social lives of monkeys , could this explain why certain monkey species have such colorful faces while others have simpler, plainer ones ?
To test this theory , a group of researchers from UCLA studied 139 monkey species , mainly from Asia and Africa, and analyzed hundreds of headshot (头像）photos of those monkeys from their databases.
It was found that species that live in larger groups have faces with more complex color patterns than those that live in smaller groups. According to Live Science, researchers believe that this is nature’s way of making it easier for monkeys to recognize each other since those living in larger groups have to distinguish between a greater number of faces.
This is actually not that hard to understand . Just imagine if there were 10 people standing in front of you, all wearing white clothes. It would be much more difficult to tell them apart than if they wore clothes with colorful patterns. However, if there were only two people that you had to identify, a lack of color wouldn’t be much of a problem.
Apart from the need to recognize group members , researchers found that geography and environment also affect monkeys’ facial colors. Species that live closer to the equator in thick, humid (潮湿的）forests were found to have darker faces than those who live in dry areas further away from the equator. This is because darker faces help camouflage (伪装）the monkeys in the woods so that they go unnoticed by predators (捕食者）.
小题1:We can learn from the article that monkeys mainly recognize each other by their __.
| A．Smells | B．Facial appearances | C．body shapes | D．Voices |
| A．Larger monkeys have more complex face color patterns. |
| B．Monkeys with colorful face patterns usually take higher social positions within groups. |
| C．Monkeys living in smaller groups usually have simpler, plainer face patterns. |
| D．Colorful face patterns keep monkeys safe from predators. |
| A．The social lives of monkeys. |
| B．How monkeys tell each other apart. |
| C．A comparison between the face patterns of monkeys and those of human beings. |
| D．The different factors that determine monkeys’ face patterns. |
A new study finds that fear of losing your phone is a common illness. About 66 percent of those surveyed suffer from nomophobia or “no mobile phone phobia”. Interestingly, more women worry about losing their phone than men.
Fortunately, there’s a solution.
The first step is to figure out if you have nomophobia. Checking your phone too often is one thing, but the true sign of a problem is that you can’t conduct business or go about your routine when the fear becomes so severe.
Do you go to unusual lengths to make sure you have your phone? That’s another sign of a problem. If you find you check your phone plenty of times per hour, or a total of an hour per day, there may be a problem.
Some of the treatments are similar to those for treating anxiety attacks: Leaving the phone behind and not checking e-mail or text messages, and then learning to tolerate the after anxiety. Even if this leads to a high level of worry and stress, the solution is to push through the fear and learn to deal with not having your phone.
Of course, there are also technological alternatives. Luis Levy, a co-founder at Novy PR, says he uses an application called Cerberus that can automatically track the location of his phone. To find it, he can just go to a Web site and see the phone’s location.
He also insures his phone through a service called Asurion. The company’s description of its product reads like a prescription for anxiety: “60 million phones are lost, stolen or damaged each year. You’ll have complete peace of mind knowing that your phone is protected and you can quickly reconnect with family, friends and work, as soon as the very next day!”
小题1:Why does the author mention Kelly’s experience in the first paragraph?

| B．To introduce the topic for discussion. |
| C．To warn us that we should be careful. |
| D．To tell us we should get phones ready for a trip. |

| D．Independence of mobile phones. |
| A．Avoiding using phone for some time |
| B．Learning more about modern technology. |
| C．Protecting one’s phone against any damage. |
| D．Not using a mobile phone in one’s daily work. |
| A．It lets you know other people also lose their phones. |
| B．It will give you a new phone through insurance. |
| C．It enables you to reconnect with your acquaintance. |
| D．It gives you a prescription to treat nomophobia. |
| A．Solutions to nomophobia. | B．New mobile phone technology. |

In the study, women who were new mothers scored better on tests of visuospatial memory – the ability to understand and remember information about their surroundings—compared with women who didn’t have children.
The findings contradicts the old belief that women develop“baby brain" or a decline in memory and cognitive(认知的) function, after they have kids, said study researcher Melissa Santiago, a doctoral student at Carlos Albizu University in Miami. “You don’t have to feel that because you have kids, your memory isn’t the same," Santiago said.
The study was small, and the findings will have to be tested in larger groups of people, Santiago said.
Previous studies on the topic have had mixed results—some showed motherhood hurts cognition, and others showed the opposite. Studies on rats show those with pups have better memory than those without offspring.
Santiago analyzed information from 35 first-time mothers whose children were ages 10 to 24 months, and 35 women who had never been pregnant. Both groups scored similarly on intelligence tests. The average age of mothers was 29 and the average age of never-pregnant women was 27.
To test visuospatial memory, the women were shown a paper containing six symbols for 10 seconds, and then asked to draw what they remembered. This task was repeated several times. The first time women were shown the paper, both groups remembered about the same amount. But on the second and third pass, mothers performed better than those without children, indicating that the mothers collected more information each time than the other women.
Later, the women were shown a variety of different symbols, and asked to remember which ones were presented on the earlier task. Mothers did not make a mistake in this task—they remembered every symbol correctly—but those without children made one or two errors, Santiago said.
小题1: How did Santiago lead to the findings?
| A．By observation. | B．By comparison. |
| C．By analyzing intelligence tests. | D．By asking women questions. |
| A．The study received little attention. |
| B．The study has just started. |
| C．The study was carried out among a small group of people. |
| D．A small group of researchers were involved in the study. |
| A．Ways to test visuospatial memory. |
| B．Why having kids improves memory. |
| C．How young mothers are different from never-pregnant women. |
| D．The negative effects that worries of women without children have. |
| A．may cause a heated discussion among parents |
| B．may cause an increase in the birth rate |
| C．are tested by previous similar studies |
| D．are encouraging news for mothers |
