第6题：英国哲学家伯特兰•罗素有一个关于归纳主义者火鸡的故事。在火鸡饲养场里，有一只火鸡发现，第一天上午9点钟主人给它喂食。然而作为一个卓越的归纳主义者，它并不马上作出结论。它一直等到已收集了有关上午9点给它喂食这一经验事实的大量观察；而且，它是在多种情况下进行这些观察的：雨天和晴天，热天和冷天，星期三和星期四……它每天都在自己的记录表中加进新的观察陈述。最后，它的归纳主义良心感到满意，它进行归纳推理，得出了下面的结论：“主人总是在上午9点钟给我喂食。”可是，事情并不像它所想像的那样简单和乐观。在圣诞节前夕，当主人没有给它喂食，而是把它宰杀的时候，它通过归纳概括而得到的结论终于被无情地****了。大概火鸡临终前也会因此而感到深深遗憾。
在这则故事中，火鸡的归纳及其失败类似于下面哪项？（）
A．在过去很长一段时间里，人们认为地球不动，太阳绕地球转，直到科学的发展****这一结论。
B．在过去很长一段时间里，由于人们一直不曾看见白色以外颜色的天鹅，认为天鹅都是白色的，直到澳州发现黑天鹅才****这一结论。
C．过去人们一直在物理上绝对相信“以太”的存在，直到爱因斯但相对论提出后，才****“以太”存在说。
D．一个识字的人出于对他所读不懂的书的神秘感，而认为“所有的书都是好的”。当然这个结论是不成立的。
E．甲地有一座金矿，综合考察乙地的各项地理条件类似甲地而认为乙地也有金矿，实际开采发觉这个结论是错误的。

第9、10、11、12、13题：Directions: There are 1 passages in this part. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and blacken the corresponding letter on the Answer Sheet with a pencil.
Questions 11 to 15 are based on the following passage:
Do you believe that only boys do well in science? Does it seem to you that girls have better vocabularies than boys? In your opinion, are boys better at building things? If your answer to each of those questions is “Yes,” you are right according to an article in “Current Science .” There are exceptions, but here are the facts.
On the average, males score higher on tests that measure mathematical reasoning, mechanical ability, and problem-solving skills. Females show superior ability in tests measuring vocabulary, spelling, and memory. But these difference will probably not always exist. In the future, a person’s abilities may not be determined by sex. As one scientist says, “Nothing is impossible for a person to be or do.”
In several recent studies, young babies have been observed and tested to discover how different abilities are developed. A scientific team headed by Jerome Kagan, a psychologist at Harvard University, is studying the thinking ability of children 111/2 months old. The test is a simple one. The baby, while seated on its mother’s lap, watches a “show” on a theater stage.
In act I of the show, an orange-colored block is lifted from a blue box and moved slowly across the stage. Then it is returned to the box.
This is repeated six times. Act 2 is similar, except that the orange block is smaller. Baby boys do not seem to notice the difference in the size of the block, but girls immediately become excited and begin to make noises that sound like language. They seem to be trying to talk.
It is known that bones, muscles, and nerves develop faster in baby girls. Usually, too, baby girls talk at an earlier age than boys do. Scientists think there is a physical reason for this. They believe that the nerve endings in the left side of the brain develop faster in girls than in boys. And it is this side of the brain that strongly influences an individual’s ability to use words, to spell, and to remember things.
By the time they start to school, therefore, little girls have an advantage that boys do not have. Girls are physically more ready to remember facts, to spell, and to read. These, of course, are skills that are important in elementary school.
But what have the boys been doing in the years before starting school? They have been developing something called aggression. An aggressive person has courage and energy. He feels strong and independent. He is often the first one to start a fight.
( )11. According to an article in “Current Science”, which of the following is false?
A. Boys do well in science. B. Girls have better vocabulary than boys.
C. Boys are better at building things. D. Boys are as good as girls at science
( )12. The author of the article believes _____.
A. Males, without any exception, score higher on tests that measure mathematical reasoning, mechanical ability, and problem-solving skill
B. Females show superior ability in tests measuring vocabulary, spelling, and memory
C. It the future, sex may be a key factor that determines a person’s ability
D. The differences above probably always exist
( )13. The test made by a scientific team headed by Jerome Kagan shows _____.
A. Baby boys never notice the difference in the size of the block
B. Baby boys try to talk
C. Baby girls seem to notice the difference in the size of the block
D. Baby girls know how to use language
( )14. Concerning the difference between baby boys and girls in physical development of ability scientists believe _____.
A. the nerve endings in the left side of the brain develop faster in baby boys
B. an individual’s ability to use words, to spell, and to remember things is strongly influenced by the right side of the brain
C. both baby boys and baby girls talk at an early age
D. There is a physical reason for the difference in the development of abilities of baby boys and baby girls
( )15. The author implies in the last two paragraphs that _____.
A. little girls have an advantage in elementary school
B. boys are physically more ready to remember facts, to spell, and to read
C. after starting school, boys begin to develop something called aggression
D. girls feel strong and independent
