The brain of an insect isn’t very big. But insects are somehow still able to make lots of important decisions. Bees, ants and roaches(蟑螂) build hives with thousands of workers doing specialized work. The jobs are done without a head or even a plan. How do insects manage this?
To solve the mystery, scientists in Belgium spent months building robotic roaches and then putting them among real roaches. The final goal of the research is to find out how the simple behavior of individuals gives rise to a collective(集体的) decision. The roach is a good starting point for trying to answer the big question because its social system is simple enough for scientists to study.
The first step was to build robots that real roaches would accept as their own. Although the robotic roaches don’t look much like the real thing, they have similarities with them in three key ways: they naturally head toward dark areas, they are influenced by the behavior of other roaches, and even more importantly, they smell like roaches.
The next step was getting the robotic and real roaches to work together on common tasks. In experiments, the robots would collectively head towards a dark place, copying the behavior of natural roaches. That got the researchers wondering: if you program the robotic roaches to go toward the lighted place, will the real roaches follow, going against their natural instincts.(本能) ?
They will – it turned out. Many of the real roaches followed the robots to a lighter shelter. But influence turned out to be a two- way street. On occasion, the real roaches were able to override the programming of the robot roaches and get them to turn into dark hiding places. Being social creatures, both the robotic and natural roaches were paying attention to and following the example set by others.
In theory, it would be possible to create a robot that could influence collective decision-making in humans. To do this, researchers would have to invent a robot that people would accept. Fortunately, the technology isn’t there yet.
69. Why do scientists choose the roaches to study?
A. Their social system is simple
B. They are social creatures.
C. They are able to build their hives quite well.
D. It is easy to create robotic ones.
70. The robotic roaches are accepted by real ones because of all the following EXCEPT that ______ .
A. they smell like real ones B. they look exactly like real ones
C. what they do are somewhat influenced by other roaches
D. they naturally head toward dark areas
71. What’s the author’s attitude to creating a robot that would influence collective decision-making in humans?
A. Uninterested B. Positive
C. Negative D. Doubtful
72. Which of the following might be the best title of the passage ?

Can you believe your eyes? A recent experiment suggests that the answer to that question may depend on your age.
Martin Doherty, a psychologist at the University of Stirling in Scotland, led the team of scientists. In this experiment, Doherty and his team tested the perception(观察力) of some people, using pictures of some orange circles. The researchers showed the same pictures to two groups of people. The first group included 151 children aged 4 to 10, and the second group included 24 adults aged 18 to 25.
The first group of pictures showed two circles alone on a white background. One of the circles was larger than the other, and these people were asked to identify the larger one. Four-year-olds identified the correct circle 79 percent of the time. Adults identified the correct circle 95 percent of the time.
Next, both groups were shown a picture where the orange circles, again of different sizes, were surrounded by gray circles. Here’s where the trick lies in. In some of the pictures, the smaller orange circle was surrounded by even smaller gray circles — making the orange circle appear larger than the other orange circle, which was the real larger one. And the larger orange circle was surrounded by even bigger gray circles — so it appeared to be smaller than the real smaller orange circle.
When young children aged 4 to 6 looked at these tricky pictures, they weren’t fooled — they were still able to find the bigger circle with roughly the same accuracy as before. Older children and adults, on the other hand, did not do as well. Older children often identified the smaller circle as the larger one, and adults got it wrong most of the time.
As children get older, Doherty said, their brains may develop the ability to identify visual context. In other words, they will begin to process the whole picture at once: the tricky gray circles, as well as the orange circle in the middle. As a result, they’re more likely to fall for this kind of visual trick.
41．Doherty and his team of scientists did an experiment to evaluate .
A．children’s and adults’ eye-sight
B．people’s ability to see accurately
C．children’s and adults’ brains
D．the influence of people’s age
42．When asked to find the larger circle, .
A．children at 6 got it wrong 79 % of the time with no gray ones around
B．only adults over 18 got it right 95% of the time with gray ones around
C．children at 4 got it right about 79 % of the time with gray ones around
D．adults got it right most of the time with gray ones around
43．According to the passage, we can know that .
A．a smaller orange circle appears bigger on a white background
B．an orange circle appears bigger than a gray one of the same size
C．a circle surrounded by other circles looks bigger than its real size
D．a circle surrounded by bigger ones looks smaller than its real size
44．Visual context may work when children get older than .
A．4 B．6 C．10 D．18
45．Why are younger children not fooled?
A．Because they are smarter than older children and adults.
B．Because older people are influenced by their experience.
C．Because people’s eyes become weaker as they grow older.
D．Because their brain can hardly notice related things together.
What can explain and solve this problem? The fact is that pollution is caused by man—by his desire for a modern way of life. We make “increasing industrialization” our chief aim. So we are always ready to offer everything: clean air, pure water, good food, our health and the future of our children. There is a constant flow of people from countryside to cities, eager for the benefit of our modern society. But as our technological achievements have grown in the last twenty years, pollution has become a serious problem.
Isn’t it time we stopped to ask ourselves where we are going—and why? It makes one think of the story about the airline pilot who told his passengers over the loudspeaker, “I’ve some good news and some bad news. The good news is that we’re making rapid progress at 530 miles per hour. The bad news is that we’re lost and don’t know where we’re going.” The sad fact is that this becomes a true story when spoken of our modern society.

These medical residents provide hospitals with needed services in return for not much pay. They work under the supervision(管理) of medical professors and more experienced doctors. Medical residents treat patients . they carry out tests. They perform operations. They complete records. In hospitals with few nurses, residents also do work formerly done by nurses. Some medical residents work one-hundred or more hours in a single week. They often work for more than thirty-six hours at a time before they can rest.
Critics (批评家) of this system say medical residents work too long and do not get enough res. They say these young doctors may be too tired to perform their medical duties effectively. Now, the government will limit the number of hours of work that residents can work. Most doctors in training will be limited to eighty-four hours of work each week. They will have work periods of no more than twenty-four hours at one time. They will have ten hours of rest between work periods.
Medical residents will have one day each week when they do not have to work. Any work they accept outside their hospitals will be limited．Experienced doctors and medical professors will closely supervise the residents to make sure they are not too tired to work.
Many medical residents welcomed the work limits. Others, however, said the new policy may interfere with patient care and their own medical education.

• About 50% of all car journeys are just for fun.
• Over 80% people go to work by car.
• 25% car journeys are under two miles.
• 70% car journeys are under five miles.
WALKING & CYCLING
Instead of using the car for short journeys, why not walk or ride a bicycle? Walking is a most popular form of exercise—it’s healthy and it can save you money. If you work nearby, try walking or cycling instead of driving. Walking your children to school gives them valuable road experience.
BUSES
Bus companies are using new buses: some run on new fuels which produce less pollution; some have easier access for disabled and old people. There are special traffic lanes (行车道) to make bus journeys easier and more reliable. So do something to help solve the pollution problem—let the bus take you to work and your children to school.
TRAINS
All car journeys, long or short, can be hard work. For some trips it is wiser to take the train. Leave your car at home and walk, cycle or take a bus to and from the station. Train travel is fast, safe and comfortable. Train tickets are not always expensive; some are quite cheap at discount.
小题1:The writer believes that ________ can give children valuable road experience.
| A．walking to school | B．travelling by train |
| C．taking new fuel buses | D．having car journeys for fun |
| A．Tiring. | B．Comfortable. |
| C．Exciting. | D．Awful. |
| A．To advise people to use cars less often. |
| B．To encourage people to travel by train. |
