In the atmosphere, carbon dioxide acts rather like a one-way mirror or the glass in the roof of a greenhouse which allows the sun's rays to enter but prevents the heat from escaping.
According to a weather expert' s prediction, the atmosphere will be 3℃ warmer in the year 2050 than it is today, if man continues to burn fuels at the present rate. If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities. Also, the increase in atmospheric temperature would lead to great changes in the climate of the northern hemisphere (北半球), possibly resulting in an alteration of the earth's chief food growing zones.
In the past, concern about a man-made warming of the earth has concentrated on the Arctic because the Antarctic is much colder and has a much thicker ice sheet. But the weather experts are now paying more attention to West Antarctic, which may be affected by only a few degrees of warming, in other words, by a warming on the scale that will possibly take place in the next fifty years from the burning of fuels.
Satellite pictures show that large areas of Antarctic ice are already disappearing. The evidence available suggests that a warming has taken place. This fits the theory that carbon dioxide warms the earth.
However, most of the fuel is burnt in the northern hemisphere, where temperatures seem to be falling. Scientists conclude , therefore, that up to now natural influences on the weather have gone beyond those caused by man. The question is: Which natural cause has most effect on the weather?
One possibility is the variable behavior of the sun. Astronomers at one research station have studied the hot spots and "cold" spots (that is, the relatively less hot spots) on the sun. As the sun rotates (使旋转), every 27. 5 days, it presents hotter or "colder" faces to the earth, and different aspects to different parts of the earth. This seems to have a considerable effect on the distribution of the earth's atmospheric pressure, and consequently on wind circulation. The sun is also changeable over a long term: its heat output goes up and down in cycles, the latest trend being downward.
Scientists are now finding shared relations between models of solar weather interactions and the actual climate over many thousands of years, including the last Ice Age. The problem is that the models are predicting that the world should be entering a new Ice Age and it is not. One way of solving this theoretical difficulty is to assume a delay of thousands of years while the solar effects overcome the inertia (惯性) of the earth's climate. If this is right, the warming effect of carbon dioxide might thus be serving as a useful opposed balance to the sun's fading heat .
It can be concluded that a concentration of carbon dioxide in the atmosphere would_________.
A. mean a warming-up in the Antarctic
B. raise the temperature of the earth' s surface
C. prevent the sun's rays from reaching the earth's surface
D. explain the cause of great changes in the climate in the northern hemisphere
The article was written to explain ___________.
A. the greenhouse effect
B. the solar effects on the earth
C. the causes affecting weather
D. the models of solar-weather interactions
Although the fuel consumption is greater in the northern hemisphere, temperatures there seem to be falling. This is__________.
A. mainly because the levels of carbon dioxide are rising
B. partly due to changes in the output of solar energy
C. possibly because the ice caps in the poles are melting
D. only due to the effect of the inertia of the earth' s climate
On the basis of their models, scientists believe the opinion that__________.
A. the climate of the world should be becoming cooler
B. the new Ice Age will be delayed by the greenhouse effect
C. the man-made warming effect helps to increase the solar effects
D. it will take thousands of years for the inertia of the earth's climate to take effect
If the assumption about the delay of a new Ice age is correct, ____________.
A. ice would soon cover the northern hemisphere
B. the greenhouse effect could work in favor of the earth
C. the best way to overcome the cooling effect would be to burn more fuels
D. the increased levels of carbon dioxide in the atmosphere could warm up the earth even more quickly

Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks’ time. Ten inches of rain may be enough for many plants to survive if the rain is spread throughout the year. If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.
Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes（沙丘）are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.
There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs（悬崖）and deep valleys were formed from thick mud that once lay beneath a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing—very, very slowly—as these forces of nature continue to work on the rock.
Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted to life in the desert. During the heat of the day, a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.
Many plants may survive in deserts when ________.
A．the rain is spread out in a year B．the rain falls only in a few weeks
C．there is little rain in a year D．it is dry all the year round
Sand dunes are formed when _______.
A．sand piles up gradually B．there is plenty of rain in a year
C．the sea has dried up over the years D．pieces of rock get smaller
The underlined sentence in the third paragraph probably means that in a desert there is ______.
A．too much sand B．more sand than before
C．nothing except sand D．something else besides sand
It can be learned from the text that in a desert _______.
A．there is no rainfall throughout the year
B．life exists in rough conditions
C．all sand dunes are a few feet high
D．rocks are worn away only by wind and heat

I had never seen sand dunes（沙丘）before. If you go to the seaside in Britain, you may see some small hills of sand, but nothing very impressive. Of course, Africa is home to many beautiful “sandscapes”, but I was in China, so I went to Dunhuang.
I had spent my first day looking at the beautiful Mogao caves. Now I wanted to experience something very different.
I have been walking in Asia, Europe and America, but nothing prepared me for walking over hills of sand. Whenever I took a step up a hill, my feet would sink into the sand and move backwards. Sometimes it seemed as if I were moving in the wrong direction.
I wanted to see the sunset so I had to climb to the top of the highest sand dune. The sun was beating down upon my back as I walked slowly over the sand. Some plants had managed to survive in the dry ground but not many.
As I climbed higher, the hills of sand became steeper and my feet started to slip further backwards. I ended up with my hands and knees, crawling (爬行)upwards through the top. I just let go if I would fall the way down. But I refused to give up: inch by inch, I made my way to the top of the sand dune.
When I got there I was amazed by what I saw. The sand formed a very sharp point, just like a knife-edge. One side of the dune was bathed in sunshine, the other covered by shade. As I looked into the distance, the same pattern was repeated on all of the hilltops, and the difference between dark and light was beautiful.
As the sun began to sink, the shadows grew longer and the light became warm and orange. The wind had come to life and sand was blown against my legs as I walked along the dunes. Soon it was getting dark and I could only just make out the line of footprints that marked my journey to the top of the hill. I slowly made my way down to the bottom, my path lit by the dying sun.
65 The author probably went to climb the sand dunes __________ after he arrived at Dunhuang.
A. on the afternoon of the first day B. on the afternoon of the second day
C. on the evening of the second day D. on the evening of the first day
66. Which of the following statements is NOT true?
A. Africa has many beautiful sand dunes.
B. The author could see nothing but his own footprints on his way back.
C. The author had seen some kinds of sand dunes before he visited Dunhuang
D. What attracted the author most was that the sand formed a very sharp point.
67. The author got to the top of the highest hill of sand _____________.
A. on his hands and knees all the way
B. with falls to the bottom many times
C. on his hands and knees in the last leg (一段旅程)
D. with a few rests all the way
68. The author mainly wants to tell readers about_____________.
A. the beautiful sunset B. his experience of climbing the sand hills
C. the joy of traveling in nature D. the difficulty of climbing the sand dunes

A little girl lived in a small, very simple, poor house on a hill and as she grew she would play in the small garden. There, she was able to see over the garden fence and across the valley to a wonderful house high on the hill. This house had golden windows, so golden and shining that the little girl would dream of how magic it would be to grow up and live in a house with golden windows instead of an ordinary house like hers. Although she loved her parents and her family, she yearned to live in such a golden house and dreamed all day about how wonderful and exciting it must feel to live there.
When she got to an age when she gained enough skill and sensibility to go outside her garden fence, she asked her mother if she could go for a bike ride outside the gate and down the lane.

She was so disappointed as she realized all the windows were plain and rather dirty, reflecting nothing other than the sad neglect of the house that was derelict.
So sad she didn't go any further and turned, and heart broken as she remounted her bike. As she glanced up she saw a sight to amaze her. There across the way on her side of the valley was a little house and its windows glistened golden as the sun shone on her little home.

Many Americans take their summer vacations in August. President Obama and his family are among them. This August the first family visited the Florida Gulf Coast. The president wants to promote tourism in the area after the BP oil spill (漏油). The first family took a ten-day vacation on Martha’s Vineyard, an island off the coast of Massachusetts.
Martha’s Vineyard is known for the sailing, sunsets and its tall cliffs overlooking the Atlantic Ocean. The island is about 13 kilometers off the coast and is less than 260 square kilometers. Homes designed like those of earlier times line the streets of Edgartown, Oak Bluffs and Vineyard Haven. These are the major towns on Martha’s Vineyard.
For most of the year, the population of Martha’s Vineyard is about 15 000. In summer, more than 100 000 people crowd the island. In addition to the Obamas, you might see some Hollywood stars and other rich and famous people. Many visitors return year after year.
During warm weather the Vineyard is a good place for many different activities. People can play golf or catch fish. They can ride in sailboats or motor boats. They can waterski and swim. They can take quiet walks along sandy beaches and among the thick green trees.
One of the popular places for families with children is the Flying Horses Carousel in Oak Bluffs. It is the oldest continually operated merry-go-round ride in the United States. The colorful wood horses that turn in a circle were created in 1876. One of the best places for children to swim is the Joseph A. Sylvia state beach. The water there is warmer and calmer. Families also enjoy the Felix Neck Wildlife Sanctuary where they can observe much of the island wildlife.
Visitors watch the sunsets sitting on the beach and on rocks in the fishing village of Menemsha. As the sun goes down in the sky it paints yellow, red, and other colors on the clouds. Fishing boats rise and fall with the waves. Bells sound to help guide the boats to land as darkness covers the water.
Historians say British mapmaker Bartholomew Gosnold first made a map of the island for the rulers of England in 1602. Gosnold named the island to honor his baby daughter, Martha. The Vineyard part of the name came from the many wild grape vines Gosnold found on the island. Later, King Charles of England gave the island to businessman Thomas Mayhew of the Massachusetts Bay Colony, whose son established the first European settlement on the island in 1642. By the middle of the nineteenth century, ships from the American mainland began bringing visitors to the island. Big hotels were built near the edge of the water. Martha’s Vineyard was on its way to becoming the visitors center that it is today.
