[1]Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy; there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”

[2]After a long pause, a boy raised his hand, “Have you ever seen a grasshopper (蚱蜢) eating? When I try eating leaves like that, I get a stomachache. Why?”

[3]This began a set of questions that lasted nearly two hours.

[4]Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical, complete and creative answers.

[5]Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good” These words work well when it comes to encouraging good behavior (行為). But in talking about science, quick praise can signal that discussions is over. Instead, keep things going by saying, “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.

[6]Never push a child to “Think”. It doesn’t’ make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target (目標(biāo)) for your disagreement.

[7]Lastly, show; don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass (放大鏡), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates (蒸發(fā)), set a pot of water to boil and let them watch the water level drop.

61. According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.

A. to let them see the world around                        B. to share the children’s curiosity

C. to explain difficult phrases about science      

D. to supply the children with lab equipment

62. In the last sentence of the first paragraph, the word “l(fā)ists” could best be replaced by _________.

A. questions from textbooks                   B. any problems  

C. any questions                                            D. any number of questions

63. According to the passage, children can answer questions in a more logical, complete and creative way if adults _____.

A. ask them to answer quickly 

B. wait for one to two seconds after a question

C. tell them to answer the next day. 

D. wait at least for three seconds after a question

64. In Which of the following paragraph(s) does the author tell us what to say to encourage children in a science discussion?

A. The second and the third.                              B. The fourth and the fifth.

C. The fifth and the sixth.                                 D. The seventh.

65. The author mentions all of the following techniques for adults to share with their children’s curiosity except that adults should ______.

A. tell their children stories instead of reciting facts.

B. offer their children chances to see things for themselves

C. be patient enough when their children answer questions

D. encourage their children to ask questions of their own

Fifty years from now the world’s population will be declining, with no end in sight. Unless people’s values change greatly, several centuries from now there could be fewer people living in the entire world than live in the United States today. The big surprise of the past twenty years is that in not one country did fertility (生育能力) stop falling when it reached the replacement rate（出生率）—2.1 children per woman. In Italy, for example, the rate has fallen to 1.2. In Western Europe as a whole and in Japan it is down to 1.5. The evidence now indicates that within fifty years or so world population will peak at about eight billion before starting a fairly rapid decline.
Because in the past two centuries world population has increased from one billion to nearly six billion, many people still fear that it will keep “exploding” until there are too many people for the earth to support. But that is like fearing that your baby will grow to 1,000 pounds because its weight doubles three times in its first seven years. World population was growing by two percent a year in the 1960s; the rate is now down to one percent a year, and if the patterns of the past century don’t change completely, it will head into negative numbers. This view is coming to be widely accepted among population experts, even as the public continues to focus on the threat of uncontrolled population growth.
As long ago as September of 1974 Scientific American published a special issue on population that described what demographers (人口統(tǒng)計(jì)學(xué)家) had begun calling the “demographic transition” from traditional high rates of birth and death to the low ones of modern society. The experts believed that birth and death rates would be more or less equal in the future, as they had been in the past, keeping total population stable after a level of 10-12 billion people was reached during the transition.
56. Which of the following statement is NOT true according to the passage?
A. The world’s population in the future will be reducing endlessly.
B. When the earth population reaches 8 billion, it will see a rapid decrease.
C. In modern society the birth and death rates will be more or less equal in the future.
D. The public now pay little attention to the threat of uncontrolled population growth.
57. What’s reason for the sharp increase of world population in the past two centuries?
A. Because people fear that the world will explode.
B. Because the world’s replacement rate keeps falling.
C. Because people’s values has greatly changed.
D. The passage doesn't mention it.
58. The expression “demographic transition” (Paragraph 3) probably means _______.
A. high death rate to the low one
B. high birth rate to the low one
C. high rates of birth and death to the low ones
D. low rates of birth and death to the high ones
59. We can learn from the passage that _______.
A. in the near future there will be a rapid decline of the world population
B. the birth and death rates of modern society will be unequal in the future
C. there would be the same population living in the world than it in the US today
D. in Western Europe the replacement rate has declined to a negative number
