Farmers can produce more by planting several different crops in the same field.But their success depends on which crops they plant together and how they mix (混合) them in the filed.In the past, the only way the farmers could learn which crops grow best together is to plant them and wait for the results.Now, however, a computer can give them answers.A new computer program written by Dr John Vanderwell of Michigan University can tell a farmer which plants grow well together and which do not.It can tell him how to plant the different crops; if he should plant each in a separate row, or mix the crops in the same row.It can tell the farmer how changes in planting each of the crops will affect the production of all of them.And it can tell him which plants can help reduce losses (損失) from diseases.

1.Which of the following best gives the main idea of the passage?

A．Computer helps find the best program for mixing plants.

B．Computer helps produce more crops.

C．Computer helps protect against insects and diseases.

D．Computer helps grow different plants.

2.According to the passage, to get the best result, one needs to choose carefully ________.

A．the kinds of crops to be planted together

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of out brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain sizes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the sizes of the front and side parts of the brain, which have something to do with thinking and feeling, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract(萎縮) with age.
Contraction of front and side parts, as cells(細(xì)胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.
The findings show that contraction of the brain begins sooner in people in the country than those in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White-collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm workers, bus drivers and shop assistants.

A．a(chǎn)t what point people grow live longer.

【小題2】Their research findings are based on ______.c
A．a(chǎn)n examination of farmers in northern Japan
B．using computer technology
C．examining the brain sizes of different people
D．tests given a thousand old people
【小題3】The doctor’s tests show that ______.
A．our brains contract as we grow older
B．one part of the brain does not contract
C．sixty-year-olds have better brains than thirty-year-olds
D．contraction of the brain begins sooner in people in the country
【小題4】 According to the article, _____ are growing mentally old earlier.
A．engineersB．office clerksC．professorsD．researchers
【小題5】The most possible conclusion of the article is that ____.
A．most of us should take more exercise
B．it’s better to live in the towns
C．the brain contracts if it is not used
D．the more one uses his brain, the sooner he becomes old
