Against the assumption that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone(臭氧)levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

The exact number of English words is not known. The large dictionaries have over half a million entries, but many of these are compound words (schoolroom, sugar bowl) or different derivatives of the same word (rare—rarely, rarefy), and a good many are obsolete words to help us read older literature. Dictionaries do not attempt to cover completely words that we can draw on: the informal vocabulary, especially slang, localism, the terms of various occupations and professions; words use only occasionally by scientists and specialists in many fields; foreign words borrowed for use in English; or many new words or new senses of words that come into use every year and that may or may not be used long enough to warrant being included. It would be conservative to say that there are over a million English words that any of us might meet in our listening and reading and that we may draw on in our speaking and writing.
Professor Seashore concluded that first?graders enter school with at least 2,000 words and add 5,000 each year so that they leave high school with at least 80,000. These figures are for recognition vocabulary, the words we understand when we read or hear them. Our active vocabulary, the words we use in speaking and writing, is considerably smaller.
You cannot always produce a word exactly when you want it. But consciously using the words you recognize in reading will help get them into your active vocabulary. Occasionally in your reading pay particular attention to these words, especially when the subject is one that you might well write or talk about. Underline or make a list of words that you feel a need for and look up the less familiar ones in a dictionary. And then before very long find a way to use some of them.
Once you know how they are pronounced and what they stand for, you can safely use them.
46. In the author´s estimation, there are ____ words in English.
A. more than half a million                B. at least 24,000
C. at least 80,000                       D. more than a million
47. The word “obsolete” most probably means ____.
A. no longer in use  B. profound   C. colorful or amusing   D. common
48. One´s recognition vocabulary is ____.
A. less often used than his active vocabulary
B. smaller than his active vocabulary
C. as large as his active vocabulary
D. much larger than his active vocabulary
49. The author does not suggest getting recognition vocabulary into active vocabulary by ____.
A. making a list of words you need and looking up the new ones in a dictionary
B. everyday spending half an hour study the dictionary
C. consciously using the words you recognize in reading
D. trying to use the words you recognize
50. From this passage we learn that ____.
A. dictionaries completely cover the words we can make use of
B. “schoolroom” is used in the passage as an example of a specialized term
C. once you know how a word is pronounced and what it represents, you have turned it into your active word
D. active vocabulary refers to words we understand when we read and hear them

閱讀理解下面的短文,然后根據(jù)短文內(nèi)容,指出能完成所給句子或回答所提問題的最佳答案。
Astronomy (天文學(xué)) is the oldest science known to man. Thousands of years ago man looked at the stars and wondered about heavens (天堂). But the six planets that he could see with his eyes alone limited man.
The Greeks studied astronomy over 2,000 years ago. They could see the size, color, and brightness of a star. They could see its place in the sky. They watched the stars move as the seasons changed. But the Greeks had no tools to help themselves study the heavens.
Each new tool added to the field of astronomy helped man reach out into space. Until there were telescopes (望遠(yuǎn)鏡), man did not know much about the moon. He did not know that the planet called Saturn (土星) had rings around it. His sight was so limited that he could not see all the planets. In the early 1700s, people thought there were only six planets. Pluto (冥王星), the last of the nine planets to be discovered was seen until 1930.
Before the spectroscopes (分光鏡), man didn’t know what kind of gas was in the sun or other stars, without radio telescopes (射電望遠(yuǎn)鏡), we did not know that radio noise came from far in space.
Today, astronomy is a growing science. We have learned more in the past fifty years than in the whole history of astronomy.
1Thousands of years ago, man watched ____ with his eyes.
A. the moon       B. the stars         C. the universe    D. all the planets
2 When the Greeks watched the stars, they could ____ .
A. know what the stars were made of     B. not see their places in the sky
C. help themselves study the heavens     D. watch the stars move as the seasons changed
3Until there were ____ , man knew very little about the moon.
A. telescopes      B. spectroscopes C. radio telescopes   D. spaceships
3People didn’t know about Pluto until ____ .
A. the 1700s      B. 2,000 years ago   C. 1930             D. thousands of years ago
5____ people began to do research on astronomy.
A. 50 years ago  B. 90 years ago  C. In the early 1700s      D. Over 2,000 years ago

We find that bright children are seldom held back by mixed-ability teaching. On the contrary, both their knowledge and experience are enriched. We feel that there are many disadvantages in streaming(按能力分班) pupils. It does not consider the fact that children develop at different rates. It can have had effect on both the bright and the not-so-bright children. After all, it can be quite discouraging to be the bottom of the top grade.
Besides, it is rather unreal to grade people just according to their intellectual(智力) ability. This is only one aspect of their total personality. We care much about the development of all the pupils’ abilities to the full, not just their study ability. We also value personal qualities and social skills, and we find that mixed-ability teaching does good to these aspects of learning.
In our classrooms, we work in various ways. The pupils often work in groups; this gives them the chance to learn to work together, to share, and to develop leadership skills. They also learn how to deal with personal problems as well as learning how to think, to make decisions, to analyze(分析) an devaluate(評(píng)價(jià)) and to communicate effectively. The pupils learn from each other as well as from the teachers.
Sometimes the pupils work in pairs; sometimes they work on individual(個(gè)人) tasks, and they can do this at their own speed. They also have some formal class teaching when this is proper. We encourage our pupils to use the library, and we teach them the skills they need in order to do this well. An advanced pupil can do advanced work and it does not matter what age the child is. We expect our pupils to do their best, not their least, and we give them every encouragement to achieve this goal.
56. By “held back” in the first paragraph, the writer means “________”.
A. made to remain in the same class            B. forced to study in the lower class
C. drawn away form their studies         D. prevented from advancing
57. The writer’s purpose of writing this passage is to ________.
A. argue for teaching bright and not-so-bright pupils in the same class
B. advise pair work and group work for classroom activity
C. offer advice on the proper use of the library
D. tell us the importance of proper formal classroom teaching
58. What would be the best title for the text?
A. Pair work.      B. Group work.    C. Mixed-ability teaching    D. Individual tasks.

Talking to plants makes them grow, especially if you ‘re a woman ,according to an experiment by the Ryal  Horticultural Society(RHS皇家園藝學(xué)會(huì)).
Women gardeners’ voices speed up growth of tomato plants much more than men’s, it found.
In an experiment that ran over a month, they found that tomato plants grew up  two inches taller if they were serenaded by the sweet tones of a female rather tha a male.
Appropriately the most effective talk came from Sarah Darwin ,whose great-great grandfather was legendary botanist(植物學(xué)家)Charles Darwin, one of the founding fathers of the RHS’ Scientific Committee. She read a passage from On the Orgin of Species and beat nine other”voices”.
Her plant grew nearly two inches taller than the best performing male and half an inch higher than her nearest competitor.
The experment began in Apirl,2009 at RHS Garden Wisley in Surrey. A variety of recorded voices were picked to play to 10 taomato plants over a month. Every plant was played a voice through headphones connected to the plant pot, and the conditions for all the plants remained the same throughout the experiment. To ensure the experiment was fair, two control plants were also left to grow in silence.
The results showed that women on average saw their plants rise by an inch on their male competitors. Some men were so bad that their plants actually grew less than a plant that was left completely alone.
Colin Crosbie, the leader at RHS, said:”We’re not sure why the female voice is more effecitive, It could be that they have a greater range of pitch and tone that affects the sound waves that hit the plant. Sound waves are an emvironmental effect just like rain or light.”
67.What is the best title for the passage?
A. Plants can’t grow faster without female voices
B. Women’s voices are more useful than men’s
C. Women’s voices make plants grow faster
D. Voices have positive effects on the growth of plants
68.The underlined word”serenaded” in Paragraph 3 most probably means”________”.
A.sung songs to
B.spoken to
C.talked about
D. played music to
69.According to the passage, ten_________were used in the experiment.
A.tomato plants
B.headphones
C. tape recorders
D.plant pots
70.What can we know about the findings of the experiment from the passage?
A. The women’s voices made the palnts grow faster by half an inch than the men’s.
B.Sarah Darwin’s plant grew 2 inches taller than her neraest competitor’s.
C. The plants which grew in silence did not necessarily grow the slowest
D. The women’s plants grew 2 inches taller than the men’s on average.

Trees are useful to man in three important ways: they give him wood and other useful things, they give him cool places, and they help to stop drought and flood.
Unluckily, in many parts of the world, man has not found that the third of these points is the most important. Man wants to make money from trees, so he has cut them down in large numbers, only to find that without them he has lost the best friends he had. And also, he is usually too careless to plant and look after new trees. So the forests slowly disappear.
This does not only mean that man will have fewer trees. The results are even worse: for where there are trees, their roots break up soil-make the rain in-and also bind the soil, thus stopping it from being washed away easily; but where there are no trees, the rain falls on hard ground and flows away, causing floods and carrying away the rich top-soil. When all the top-soil is gone, nothing is left but useless desert.
1.The most important points of trees to man is ________.
A. they help him to make money               B. they give him cool
C. they give him wood and other things       D. they help him to stop drought and floods
2.In many places forests slowly disappear because ________ .
A. many trees have been cut down by man
B. new trees are not well looked after
C. man has not paid enough attention to planting trees
D. all the above
3.Land becomes desert after all trees are cut down because ________ .
A. roots of trees break up the soil   
B. there are too many rainfalls
C. strong winds bring a lot of sand
D. there are no longer trees to keep the rain and protect the top-soil.
4.Which title best fits the passage?
A. Trees and Man                                      B. The Function of Tree Wood
C. How do People do with Trees?                  D. The Usage of Tree Roots

Animation(動(dòng)畫) means making things which are lifeless come alive and move.
Since earliest times, people have always been surprised by movement. But not until this century have we managed to take control of movement, to record it, and in the case of animation, to retranslate it and recreate it. To do all this, we use a movie camera and a projector.
In the world of cartoon animation, nothing is impossible. You can make the characters do exactly what you want them to do.
A famous early cartoon character was Felix the Cat, created by Pat Sullivan in America in the early nineteen twenties. Felix was a wonderful cat. He could do all sorts of things no natural cat could do like taking off his tail, using it as a handle and then putting it back.
Most of the great early animators lived and worked in America, the home of the moving picture industry. The famous Walt Disney cartoon characters came to life after 1928. Popeye the Sailor and his girl friend Olive Oyo were born at Max Ficischer in 1933.
But to be an animator, you don’t have to be a professional. It is possible for anyone to make a simple animated film without using a camera at all. All you have to do is to draw directly on to an empty film and then run the film through a projector.
64. Which of the following statements is TRUE?
A. People were unable to cause the movement to last or record it in the last century.
B. Pat Sullivan was a famous early cartoon character.
C. It is impossible to make cartoon characters do what they are designed to do.
D. In ancient times people were surprised by movement.
65. According to the passage, Felix the Cat________.
A. was created by the American cartoonist Felix
B. was designed by Pat Sullivan in the early twentieth century
C. was unable to do what natural cats could not do
D. was created in the United States in the nineteenth century
66. It can be inferred from the passage that ________.
A. Walt Disney’s cartoon characters were born earlier that Pat Sullivan’s
B. only professionals can create cartoon characters
C. Popeye the Sailor and Olive Oyo were famous cartoonists
D. the cartoon industry started in the United States
67. Which of the following statements best describes the author’s attitude towards cartoon making?
A. Cartoon making is an easy job. Anyone can do it.
B. Only trained people can be employed in cartoon making industry.   
C. Anyone can make cartoons under the instructions of professionals.
D. Cartoon making is no easy job. You have to spend much time drawing onto the empty film.
