A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”. This idea is dangerous.
Science can be a force for evil as well as for good. Its applications can be channeled either way, depending on our decisions. The decisions we make, personally or collectively, will determine the outcomes of science. But here is a real danger. Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference. And, rather than fighting for the best possible policies, we may step back and do nothing.
Some people go even further. They say that despite the moral and legal objections (反对), whatever is scientifically possible will be done ——somewhere, sometime. They believe that science will get out of control in the end. This belief is dangerous too, because it a fuels sense of  hopelessness and discourages them from making efforts to build a safer world.
In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science. Without a common understanding, the challenges of “controlling” science in this century will be really tough. Take human cloning for example. Despite the general agreement among scientists on its possible huge impact (影响) on traditional moral values, some countries still go ahead with the research and development of its related techniques. The outcomes are hard to predict.
Therefore, discussions on how science is applied should be extended far beyond scientific societies. Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.

You either have it , or you don’t –a sense of direction ,that is.But why is it that some people could find their way across the Sahara without a map ,while others can lose themselves in the next street?

         Scientists say we’re all born with a sense of direction ,but it is not property understood how it works.One theory is that people with a good sense of direction have simply worked harder at developing it.Research being carried out at Liverpool University supports this idea and suggests that if we don’t use it.we lose it.

         “Children as young as seven have the ability to find their way around.” says Jim Martland.Research Director of the project.“However if they are not allowed out alone or are taken everywhere by car ,they never develop the skills”

         Jim Martland also emphasizes that young people should be taught certain skills to improve their sense of direction.He makes the following suggestions.

         ●If you are using a map ,turn it so it relates to the way you are facing.

         ●If you leave your bike in a strange place ,put it near something like a big stone or a tree.

Note landmarks on the route as you go away from your bike.When you return ,go back

along the same route

         ●Simplify the way of finding your direction by using lines such as streets in a town,

streams ,or walls in the countryside to guide you.Count your steps so that you know how

far you have gone and note any landmarks such as tower blocks or hills which can help to

find out where you are.

         Now you need never get lost again!

60.Scientists believe that       .

         A.some babies are born with a sense of direction

         B.people learn a sense of direction as they grow older

         C.people never lose their sense of direction

         D.everybody posses a sense of direction from birth

61.What is true of seven-year-old children according to the passage?

         A.They never have a sense of direction without maps.

         B.They should never be allowed out alone if they lack a sense of direction.

         C.They have a sense of direction and can find their way around.

         D.They can develop a good sense of direction if they are driven around in a car.

62.If you leave your bike in a strange place ,you should     .

         A.tie it to a tree so as to prevent it from being stolen

         B.draw a map of the route to help remember where it is

         C.avoid taking the same route when you come back in it

         D.remember something easily recognizable on the route

63.According to the passage the best way to find your way around is to    .

         A.ask policemen for directions

         B.use walls.streams , and streets to guide yourself.

         C.remember your route by looking out for steps and stairs.

         D.count the number of landmarks that you see.

 

It’s not a particular brain region that makes someone smart or not smart. Nor is it the strength and speed of the connections throughout the brain or such features as total brain volume. Instead, new research shows, it’s the connections between very specific areas of the brain that determine intelligence.

“General intelligence actually relies on a specific network inside the brain, and this is the connections between the gray matter, or cell bodies, and the white matter, or connecting fibers between neurons(神经元),”said Jan Glascher, lead author of a paper appearing in this week’s issue of the Proceedings of the National Academy of Sciences.

The results weren’t entirely unexpected, said Keith Young, vice chairman at Texas A﹠M Health Science Center College of Medicine in Temple, but “it proves that good communication between various parts of brain are very important for this general intelligence.”

“People noticed a long time ago that, in general, people who are good test-takers did well in a lot of different subjects,”explained Young. “If you’re good in mathematics, you’re also usually good in English. Researchers came up with this idea that this represented a kind of overall intelligence.”

Hoping to learn more, some experts located 241 patients who had some sort of their lesions (损害). They then diagrammed the location of their lesions and had them take IQ testes. “We took patients who had parts of their brain damaged, tested them on intelligence to see where they were good and where they were bad, then we connected those scores across all the patients with the location of the brain lesions,”Glascher explained. “That way, you can know the areas that are associated with reduced performance on these tests, which means these areas are really important for general intelligence.”

“These studies suggest results based on the absence of brain tissue (组织),”added Paul Sanberg, famous professor and director of the University of South Florida Center. “It allows them to systemize and find areas important to intellingence.”

1. Which of the following is the best title for the passage?

A. General Intelligence Depend on Brain Volume

B. Scientists Explain Mysteries of Intelligence

C. Science Research Done on Human Brain

D. Brain Lesions Cause Patients Stupid

2.According to Keith Young, we can infer that_____________.

A. the parts of brain are working smooth on their own

B. a person good at maths has obstacles learning languages

C. overall intelligence will make a person successful

D. Jan Glascher’s article really shocks the world

3. Why did experts locate 241 patients with some sort of brain lesions?

A. To diagram the location of their lesions.

B. To take IQ tests to the patients.

C. To know more about the secrets of intelligence.

D. To take better care of the patients.

4.From the diagram, the experts concluded that_____________.

A. the absence of brain tissue will influence intelligence

B. the brain lesions can improve the performance

C. patients with brain lesions will get a high score

D. Some areas totally determine the ability of intelligence
