About six years ago I was eating lunch in a restaurant in New York City when a woman and a young boy sat down at the next table. I couldn’t help overhearing parts of their conversation. At one point the woman asked: “So, how have you been?” And the boy, who could not have been more than seven or eight years old, replied, “Frankly, I’ve been a little depressed lately.”
This incident stuck in my mind because it confirmed my growing belief that children are changing. As far as I can remember, my friends and I didn’t find out we were “depressed” until we were in high school.
The evidence of a change in children has increased steadily in recent years. Children don’t seem childlike anymore. Children speak more like adults, dress more like adults and behave more like adults than they used to.
Whether this is good or bad is difficult to say, but it certainly is different. Childhood as it once was no longer exists, why?
Human development is based not only on innate(天生) biological states, but also on patterns of access to social knowledge. Movement from one social rote(生搬硬套) to another usually involves learning the secrets of the new status. Children have always been taught adult secrets, but slowly and in stages: we tell sixth graders things we keep hidden from fifth graders.
In the last 30 years, however, a secret-revelation(揭示) machine has been brought in 98 percent of American homes. It is called television. Television passes information to all viewers alike, indiscriminately (不加区分地). Unable to resist the temptation, many children turn their attention from printed texts to the less challenging, more vivid moving pictures.
Communication through print, as a matter of fact, allows for a great deal of control over the social information to which children have access. Reading and writing involve a complex code of symbol that must be memorized and practices. Children must read simple books before they can read complex materials.
53. Traditionally, a child is supposed to learn about the adult world______________.
A. through contact with society
B. naturally and by biological instinct (本能)
C. gradually and under guidance
D. through exposure to social information
54. The phenomenon that today’s children seem adult like is due to ____________.
A. the widespread influence of television
B. the poor arrangement of teaching content
C. the fast pace of human intellectual development
D. the constantly rising standard of living
55. Why is the author in favor of communication through print for children?
A. It enables children to gain more social information.
B. It develops children’s interest in reading and writing.
C. It helps children to memorize and practice more.
D. It can control what children are to learn.
56. What does the author think of the change in today’s children?
A. He feels amused by their premature (早熟) behavior.
B. He thinks it is a phenomenon worthy of note.
C. He considers it a positive development.
D. He seems to be upset about it.

本文介绍了美国著名的生物学家Edward Wilson 的著作The Future of Life中的一些有关如何开发、利用和保护自然资源的情况。
Edward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources(资源). How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性)of our earth.
Wilson begins with an open letter to the pioneer in environment (环境) protection, Henry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Van the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?
Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species(物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.
At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book.
We learn from the text that Wilson cares most about ______

A.the environment for plants
B.the biodiversity of our earth
C.the wastes of natural resources
D.the importance of human values

How many species are most important to our present food supply?

A.Twenty. B.Eighty. C.One hundred D.Ten thousand.

Wilson suggests that one way to keep biodiversity is to _______.

A.learn how to farm scientifically
B.build homes for some dying species
C.make it clear what to eat
D.use more species for food

We can infer that the text is _______

A.a description of natural resources
B.a research report
C.a book review
D.an introduction to a scientist.

A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃. Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover,these areas would reflect more heat into the atmosphere,warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns,potentially causing certain natural disasters all over the world.

In the past hundred years,humans have begun destroying rainforests in search of three major resources(资源):land for crops,wood for paper and other products,land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.There are two main reasons for this. Firstly,when people cut down trees,generally they can only use the land for a year or two. Secondly,cutting large sections of rainforests may provide a good supply of wood right now,but in the long run it actually reduces the world's wood supply.

Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However,fewer than l%of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests.

B.the percentage of the White families with a computer remained unchanged
C.the number of the Black families with a computer was on the decrease
D.the number of the Asian families with a computer showed the sharpest increase

Sometimes, the simplest ideas are the best. For example, to absorb heat from the sun to heat water, you need large, flat, black surfaces. One way to do that is to build those surfaces specially, on the roofs of buildings. But why go to all that trouble when cities are rub of black surfaces already, in the form of asphalt (柏油) roads?
Ten years ago, this thought came into the mind of Arian de Bondt, a Dutch engineer. He finally persuaded his boss to follow it up. The result is that their building is now heated in winter and cooled in summer by a system that relies on the surface of the road outside.
The heat-collector is a system of connected water pipes. Most of them ran from one side of the street to the other, just under the asphalt road. Some, however, dive deep into the ground.
When the street surface gets hot in summer, water pumped through the pipes picks up this heat and takes it underground through one of the diving pipes. At a depth of 100 metres lies a natural aquifer (蓄水层) into which several heat exchangers (交换器) have been built. The hot water from the street runs through these exchangers, warning the ground-water, before returning to the surface through another pipe. The aquifer is thus used as a heat store.
In winter, the working system is changed slightly. Water is pumped through the heat exchangers to pick up the heat stored during summer. This water goes into the building and is used to warm the place up. After performing that task, it is pumped under the asphalt and its remaining heat keeps the road free of snow and ice.
Which of the following is true according to the first two paragraphs?

A.Arian de Bondt got his idea from his boss.
B.Large, flat, black surfaces need to be built in cities.
C.The Dutch engineer's system has been widely used.
D.Heat can also be collected from asphalt roads.

For what purpose are the diving pipes used?

A.To absorb heat from the sun.
B.To store heat for future use.
C.To turn solar energy into heat energy.
D.To carry heat down below the surface.

From the last paragraph we can learn that __

A.some pipes have to be re-arranged in winter
B.the system can do more than warming up the building
C.the exchangers will pick up heat from the street surface
D.less heat may be collected in winter than in summer.

The year 2009 is the Year of Ox. The ox is a representative of the fanning culture of China. In the farming economy (经济), oxen are the major animals pulling plows (犁).
Of course, the good of oxen is not limited to plowing. In fact, they are seen as "boats on land" for their ability to carry loads. Besides, the whole body of an ox is full of treasures. Their meat and milk are food full of nutrition, and their skin can be used to make clothes and shoes. With all these qualities, oxen are regarded as generous creatures.
In the past, oxen played an important role in the spiritual life of the Chinese. Even today, oxen still play a special part in some folk activities. For example, some people who1ire in southwest China will cook cattle bone soup and share it among family members when holding the ceremony for children who reach 13. They believe that the cattle bone soup represents the blood relationship among family members. In order to express their love for oxen, people in some other areas will run to shake off diseases on the 16th day of the first month by the lunar calendar (农历), and during their run they will take their oxen along, which indicates they regard the creature as human.
Because of the contribution of oxen in their lives, the Chinese people are very grateful to the animal. In addition, the use of oxen in ceremonies and the thanks people owe to oxen help to develop various traditional customs, which becomes an important part of the folk culture of the Chinese nation.
The words "boats an land" underlined in Paragraph 2 refer to __

A.animals for taking goods B.creatures for pulling plows
C.treasures of the folk culture D.tools in the farming economy

From the third paragraph, we know that __

A.oxen are no more important today than in the past
B.ceremonies are held when people cook cattle bone soup
C.oxen are treated as human in some areas of China
D.people run with oxen to shake off diseases every month

Which of the following helps to develop traditional customs?

A.The special role of oxen in frowning.
B.People's respect and love for oxen.
C.The practical value of an ox's body.
D.The contribution of oxen to the economy.

Why does the author write the text?
