最近，你是吴明，和笔友李华都很关注“可持续发展”的话题。现在你写一封信给他，谈
谈江苏的省情，介绍耕地的使用及保护的情况。
词数：150左右。信的开头号和结尾已经给出。必须包含以下要点：
1、江苏是我国经济发达的省份之一，位于我国的东部，人口多，耕地少。
人口：7000多万；土地面积：10多万平方公里。自然资源贫乏。
2、随着经济的发展和人口的增长，越来越多的良田被征用来建造住房和工厂。耕地面积逐年减少。
3、人们正认识到保护耕地的重要性，政府积极采取措施禁止非法用地。
4、保护土地资源，是每个公民应尽义务，也是造福子孙后代的需要。
Dear Li Hua,
How are you? With this letter I'd like to introduce my hometown—Jiangsu Province to you．
Looking forward to your reply.
Best wishes.
Most scientists are now certain that global warming is taking place．Gases such as carbon
dioxide produced by burning of coal, oil, wood, together with industrial pollution, are creating a
warm blanket around the earth．This blanket is trapping heat in the atmosphere and so raising the
temperature of the earth.
The evidence for global warming can now be seen in the world’s changing climate statistics．In
Europe, eight of the last ten years have seen record high temperature．For northern Europe, this has
generally been a change for the better．Gardens can even now grow tropical（热带的） plants in
England, though London may never see a “White Christmas” again．On the other hand, the
countries around the Mediterranean Sea, and those south of the Sahara desert are receiving even
less rain than before．In sub-Saharan Africa the crops are drying out in the fields and people are
dying of starvation．In the Americas, the climate is becoming more extreme ---the summers are
getting hotter and hotter and the storms are becoming more violent．In 1999 the southern United
States was struck by a series of destructive hurricanes, while the end of 1999 saw the worst floods
ever in Venezuela．Meteorologists（气象学家） expect such trends to continue, and indeed to
worsen, if global warming cannot be halted(终止).
In addition to worrying about rising global temperatures and more extreme weather conditions,
scientists are closely monitoring（监测）sea levels around the world．These are slowly rising, as the northern and southern polar ice-caps start to melt．This will have serious consequences for low-lying countries near the sea, such as the coral islands in the Pacific, and Bangladesh where the River Ganges already folds the delta(三角洲) every year．Already parts of these places are disappearing under the rising tides.

How much can environment affect intelligence? In one study, striking increases in IQ occurred
in 25 children who were moved from an orphanage(孤儿院) to more stimulating（使人兴奋的，使人振奋的） environments．The children, who were all considered mentally retarded and unadoptable, were moved to an institution where they received personal attention from adults．Later, these supposedly retarded children were adopted by parents who gave them love, a family ,and a stimulating home environment．The children gained an average of 29 IQ points．For one child, the increase was an amazing 58 points．A second group of initially less "retarded" children, who stayed in the orphanage, lost an average of 26 IQ points.
Other encouraging results can be found in early childhood education programs, which provide
stimulating intellectual experiences for disadvantaged children．In one study, children from low-income families were given enriched environments from early infancy(婴儿期) through preschool．By age 2 their IQ scores were already higher than those in a control group．More important, they were still 5 points higher seven years later．High-quality enrichment programs such as Head Start can prevent children from falling behind in school.
A particularly striking environmental effect is the fact that 14 nations have shown average IQ
gains of from 5 to 25 points during the last 30 years．These IQ boosts, averaging 15 points, occurred in far too short a time for genetics to explain them．It is more likely that the gains reflect environmental forces, such as improved education, nutrition, and living in a technologically complex society.
1.What's the main idea of this passage
A．Retarded children cannot improve their IQ's.
B．Orphanages are full of mentally retarded children.
C．Environmental factors influence a child's IQ.
D．Early childhood education programs are important.
2.The author is in favor of _____________ according to the passage.
A．putting retarded children into institutions
B．providing early childhood education programs
C．keeping children in orphanages
D．keeping retarded children with others like themselves
3.Which of the following is NOT mentioned as an environmental factor that affects IQ .
A．Good nutrition． B．Improved technology.
C．Better education． D．Food pollution.
4.What can we conclude from the passage ?
A．Attention from parents has little effect on a child's IQ.
B．Head Start programs are a waste of money.
C．Increases in IQ have happened in the US more rapidly than elsewhere.
D．Genetics are less important than environment in gaining one's IQ.
Have you ever thought, “I wish I could take a year off and just travel around the world”? Well,
three lucky American teenagers were able to do just that．The teens—two males and one female--got an all-expenses paid, yearlong hike to five continents.
This trip didn’t include any five-star hotels or shopping funs．Eighteen-year-old Jamie Fiel
from Keller, Texas, 17-year-old Arsen Ewing from Canyon, California, and 16-year-old Tyler Robinson from Lincoln, Massachusetts, didn’t expect fancy treatment．They signed up for the experience of a lifetime, which included hard work, often uncomfortable accommodations, and encounters with（遭遇） some of nature’s most dangerous animals and environments.
Jamie, Arsen, and Tyler were among hundreds of high school kids nominated by their science
teachers to take this trip．Earthwatch Institute sponsored this adventure．Each year, Earthwatch employs thousands of volunteers worldwide to help with scientific research projects．
The group went all around the world to get a close look at the most pressing environmental
issues of our time．Their assignments were as varied as their locations, and included measuring and attending pink flamingos in Kenya’s Great Rift Valley, and tracking giant sea turtles in Costa Rica.
As they worked with the Earthwatch scientists, Jamie, Arsen, and Tyler began to understand
that we are at a critical moment in the life of our planet．Time for change is running out．As the teens went from country to country and witnessed different environmental dangers and challenges, they understood that solutions to important environmental issues start with the power of one person's actions．They realized that each of them can make a difference.
1.These teenagers went on the journey around the world _____.
A．to experience the most serous environmental problems on the earth
B．to bring the kindness of America to the other parts of the world
C．to go on sightseeing around the world
D．to call on more teenagers to join Earthwatch Institute
2.What’s true about their journey?
A．They had to pay for their journey at their own expense.
B．They often had to move from one hotel to another.
C．They had to take great pains to collect environmental information.
D．They received a warm welcome every time they arrived at a new place.
3.It can be inferred that Earthwatch Institute could be _____．
A．an international university that takes in students from all over the world
B．a TV station that makes programmes on the beautiful scenery of the earth
C．a travel agency that organizes adventure trips specially for school children
D．an organization that brings science to life for people concerned about the earth’s environment
4.What did they these teenagers learn from the journey?
A．It was high time that people protected the environment.
B．Long journey was not suitable for school children.
C．It should take the whole world to help the children.
D．Environmental problems can be solved if school children take part.
