科學(xué)家尋找礦物的專屬區(qū)域
Flying over a desert area in an airplane, two scientists looked down with trained eyes at trees and bushes. After an hour's 11 one of the scientists wrote in his book, "Look here for 12 metal. " Scientists in another airplane, flying over a mountain region, sent a 13 to other scientists on the ground, "Gold possible. " Walking across hilly ground, four scientists reported, "This ground should be searched for metals. " From an airplane over a hilly wasteland a scientist sent back by radio one word, "Uranium. "
None of the scientists had X-ray eyes: they had no 14 powers for looking down below the earth's surface. They were 15 putting to use one of the newest methods of 16 minerals in the ground—using trees and plants as 17 that certain minerals may lie beneath the ground on which the trees and plants are growing.
This newest method of searching for minerals is 18 on the fact that minerals deep in the earth may 19 the kind of bushes and trees that grow on the surface.
At Watson Bar Creek, a brook six thousand feet high in the mountains of British Columbia, Canada, a mineral search group gathered bags of tree seeds. Boxes were filled with small branches from the trees. Roots were dug and put into boxes. Each bag and box was 20 marked. In a scientific laboratory the parts of the forest trees were burned to ashes and tested. Each small part was examined to learn whether there were minerals in it.

人類大腦智力的決定因素
There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably , some being more capable than others. But no matter how good a brain he has to begin with, an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual— the sort of environment in which he is brought up. If an individual is handicapped(不利) environmentally, it is likely that his brain will fail to develop and he will never attain the level of intelligence of which he is capable.
The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, and their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate foster(撫養(yǎng)) homes. Peter was raised by parents of low intelligence in an isolated community with poor educational opportunities. Mark was reared in the home of well-to-do parents who had been to college. He was read to as a child, sent to good schools, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Mark's I. Q. was 125, twenty-five points higher than the average and fully forty points higher than his identical brother. Given equal opportunities, the twins, having identical brains, would have tested at roughly the same level.

我的朋友索菲亞布倫特
Sophy Brent came to visit me nearly every day. She made me feel uneasy most of the time. She smoked 11 and never used an ashtray. She followed me into the kitchen while I made tea or coffee or supper and 12 herself to the children's orange juice. She made a great hit with my two-year-old daughter Flora, who would 13 about her for hours and refer to her lovingly as "sofa", and she was always talking about my husband and asking me where he was.
I could not decide why she chose my 14 , although I realized that nobody else paid her very much attention. Her situation was very difficult in that she was 15 out of drama school and only nineteen, but being 16 to play a leading part in a company of fairly 17 and experienced actors. They would not have liked her much even if she had been good, and as, from all accounts, she was not good so they took every 18 to run her down. I think she thought that I was the only person around who was both unconnected with the theatre and tolerably 19 . To associate with me was not, at any rate, to step down the scale. And for my part, although I felt troubled by her I did not dislike her. There was something genuinely outstanding in her personality, and she had such physical 20 that with me she could get away with anything. She was nice to have around, like flowers or a bowl of fruit.
