American’s genius with high technology may have put men on the moon, but there is growing doubt about its ability to solve human problems closer to home.

In fact, a slight but significant change from purely technological solutions is already under way as scientists insist that answers to the world’s problems will not come from an attractive exhibition of electronics and machines. Instead, as they see it, solutions must develop from a better understanding of the humans that drive the system and from a fuller appreciation of the limits and potential(潜能) of the earth’s resources.

What this means is an increased emphasis on the life and earth sciences, on sociology, psychology, economics and even philosophy.

More and more of the best minds in science, particularly young researchers, are being drawn into these developing fields.

All this is not to say that technological creativity will not play a critical role in solving energy and food shortages, or that answers to environmental difficulties will not come from further advances in the same technologies that may have helped cause the problems.

Where the real challenge lies, in the view of the new generation of scientists, is in finding ways to produce goods and meet the world’s needs, using less of the raw materials that are becoming short.

Which of the following would the author probably agree with?

A. The environment crisis will not be solved unless we stop using virgin（原始）materials.

B. In scientific research, a higher priority（优先）should be given to understanding all living systems.

C. Exploration of outer space will finally lead to an improvement on human living conditions.

D. U. S. high-technology companies are welcoming this new change in scientific research.

Which of the following best expresses the main idea?

A. a growing number of Americans are doubtful about what high technology can do in solving the world’s problems.

B. Many scientists are beginning to believe that the better understanding of human beings will play a more decisive role in solving the world’s problems.

C. More and more young scientists are trying their best to find new ways to solve the world’s problems.

D. Technological creativity will still play a very important part in solving the world’s problems.

Young scientists demand that in order to satisfy human needs ________.

A. existing products be improved.

B. more complex machines and electronic equipment be designed.

C. ways be found to produce better goods using fewer raw materials.

D. any new invention and innovation be encouraged in technology

In the passage “Human problems” or “world problems” refers mainly to ______.

A. global food shortage B. resources depletion（耗尽）

C. environmental pollution D. all of the above

The author states all the following CXCEPT that _______.

A. the development of present techniques cannot provide any answers to today’s problems.

B. an increasing number of young scientists are taking a great interest in biological and social sciences.

C. many scientists have come to understand the limits of natural resources.

D. many scientists argue that high technology is something but not everything.

Nearly two thousand years have passed since a census decreed by Caesar Augustus become part of the greatest story ever told. Many things have changed in the intervening years. The hotel industry worries more about overbuilding than overcrowding, and if they had to meet an unexpected influx, few inns would have a manager to accommodate the weary guests. Now it is the census taker that does the traveling in the fond hope that a highly mobile population will stay long enough to get a good sampling. Methods of gathering, recording, and evaluating information have presumably been improved a great deal. And where then it was the modest purpose of Rome to obtain a simple head count as an adequate basis for levying taxes, now batteries of complicated statistical series furnished by governmental agencies and private organizations are eagerly scanned and interpreted by sages and seers to get a clue to future events. The Bible does not tell us how the Roman census takers made out, and as regards our more immediate concern, the reliability of present day economic forecasting, there are considerable differences of opinion. They were aired at the celebration of the 125th anniversary of the American Statistical Association. There was the thought that business forecasting might well be on its way from an art to a science, and some speakers talked about newfangled computers and high-falutin mathematical system in terms of excitement and endearment which we, at least in our younger years when these things mattered, would have associated more readily with the description of a fair maiden. But others pointed to the deplorable record of highly esteemed forecasts and forecasters with a batting average below that of the Mets, and the President-elect of the Association cautioned that “high powered statistical methods are usually in order where the facts are crude and inadequate, the exact contrary of what crude and inadequate statisticians assume.” We left his birthday party somewhere between hope and despair and with the conviction, not really newly acquired, that proper statistical methods applied to ascertainable facts have their merits in economic forecasting as long as neither forecaster nor public is deluded into mistaking the delineation of probabilities and trends for a prediction of certainties of mathematical exactitude.

[B]. statistics is not as yet a science.

[C]. statisticians love their machine.

[D].computer is hopeful.

The “greatest story ever told” referred to in the passage is the story of

Almost everyone wants to get smarter. We struggle to improve our 16_ , intelligence and attention. We drink cup after cup of coffee to help us 17_ the day.

18 __, a new study published in Current Directions in Psychological Science warns that there are 19___ to how smart humans can get.

Each of our body parts develops in a certain way for a reason. 20 _, we are not 3 meters tall 21 _ most people’s hearts are not strong enough to send 22 _ up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __23 , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more 24 during childbirth.

The study of Jews, who have an average IQ much _ 25_ than other Europeans, showed they were more _26_ to develop diseases of the _27_ system. This might be because of their increased brainpower.

If intelligence cannot be improved, can we at least get better at _ 28 _ ? Not really, say scientists. They studied _29_ like caffeine (咖啡因)that improve attention. They found the drugs only helped people with serious 30 _ problems. For those who did not have trouble paying attention, the drugs could have the 31 _ effect. Scientists say that this suggests there is a(n) 32 limit to how much people can or should concentrate.

Our memory is also a “double-edged sword”. People with extremely good memories could 33__ having a difficult life because they cannot _34 bad things that happen to them.
