By 2050

Futurologists（未来学家）predict that life will probably be very different in 2050.

TV channels（频道）will have disappeared. Instead, people will choose a program from a “menu” and a computer will send the program directly to the television. Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers, and books will come to us by computer.

Cars will run on new, clean fuels and they will go very fast. Cars will have computers to control the speed and there won’t be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination. Space planes will take people halfway around the world in 2 hours. Today, the United States Space Shuttle can go into space and land on Earth again. By 2050, space planes will fly all over the world and people will fly from Los Angeles to Tokyo in just 2 hours.

Robots will have replaced people in factories. Many factories already use robots. Big computers prefer robots—they don’t ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

Medical technology will have conquered many diseases. Today, there are devices（设备）that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again.

Scientist will have discovered how to control genes（基因）. Scientists have already produced clones（克隆）of animals. By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?

1.According to the passage, the following can be realized today EXCEPT __________.

C
Wind is the movement of air from an area of high pressure to an area of low pressure. In fact, wind exists because the sun unequally heats the surface of the Earth. As hot air rises, cooler air moves in to fill the gap. As long as the sun shines, the wind will blow. And as long as the wind blows, people will manage it to power their lives.
Ancient sailors used sails to capture the wind and explore the world. Farmers once used windmills to grind their grains and pump water. Today, more and more people are using wind turbines to make electricity from the breeze. Over the past decade, wind turbine use has increased at more than 25 percent a year. Still, it only provides a small part of the world's energy.
Most wind energy comes from turbines that can be as tall as a 20-story building and have three 200-foot-long (60-meter-long) blades. These devices look like giant airplane propellers(螺桨)on a stick. The wind spins the blades, which turn a shaft connected to a generator.
The biggest wind turbines generate enough electricity to supply about 600 U.S. homes. Wind farms have tens and sometimes hundreds of these turbines lined up together in particularly windy spots, like along a ridge. Smaller turbines set up in a backyard can produce enough electricity for a single home or small business.
Wind is a clean source of renewable energy that produces no air or water pollution. And since the wind is free, operational costs are nearly zero once a turbine is erected. Mass production and technology advances are making turbines cheaper, and many governments decrease tax to encourage wind-energy development.
Some people think wind turbines are ugly and complain about the noise the machines make. The slowly rotating blades(螺旋风片) can also kill birds and bats, but not nearly as many as cars, power lines, and high-rise buildings do. The wind is also changeable: If it's not blowing, there's no electricity generated.
Nevertheless, the wind energy industry is increasing sharply. Globally, generation more than quadrupled(四倍) between 2000 and 2006. At the end of last year, global capacity was more than 70,000 megawatts. In the energy-hungry United States, a single megawatt is enough electricity to power about 250 homes. Germany has the most installed wind energy capacity, followed by Spain, the United States, India, and Denmark. Development is also fast growing in France and China.
Industry experts predict that if this pace of growth continues, by 2050 the answer to one third of the world's electricity needs will be found blowing in the wind
63. According to the passage, which of the following statements is true?
A. The rotating blades can kill as many birds as high-rise buildings do
B. Single families are not encouraged to build turbines.
C. The USA produces more wind power than any other country in the world.
D. The noise the turbines make may discourage people from building them.
64. The underlined word “generator” in the third paragraph probably means_______.
A. 电动机                 B. 发电机                    C. 机翼                       D. 飞机引擎
65. If the USA wants to build wind turbines in an area with 30,000 homes, how many
should they build at least?
A. 50.                          B. 150.                         C. 250.                         D. 200.
66. All the following are the advantages of wind energy EXCEPT that_________.
A. it is environmentally friendly                        B. it is free to build and operate
C. the government supports it                                   D. the energy is clean and renewable

Will life in the future be better, worse or the same as now? Futurologists（未来学家）predict that life will probably be very different in 2050.
First of all, it seems that TV channels will have disappeared by 2050. A computer will send the program directly to the television. On TV screen appear holograms（全息图）, which are pictures with certain height, width and depth. We will be able to see, smell and touch the things that we see on television.
Water has become one of our most serious problems. Agriculture is changing and people are growing more fruit and vegetables to export. Demand for water will increase ten times in 2050. Some futurologists predict that water will be the cause of war if we don’t act now.
In transport, cars will run on new fuels and go very fast. A car will have computers to control its speed and there won’t be any accidents. On the other hand, space planes will take people around the earth in about three hours. People will fly from Los Angeles to Tokyo by space plane in just half an hour.
In the field of technology, robots will have replaced people in factories. By 2050, we will see robots everywhere. They do not ask for pay rises or go on strike, and they work 24 hours a day. 
Medicine technology will have conquered many diseases by 2050; we will be able to help blind and deaf people see again and hear again. Scientists have discovered how to control genes. They have already produced clones of animals and will be able to produce clones of people and decide how they look, how they behave and how much intelligence they have. If you want all this to come true, you should study science and technology hard.

   Sustainable development is applied to just about everything from energy to clean water and economic growth, and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use. This is especially true in agriculture, where sustainable development is often taken as the only measure of progress without a proper appreciation of historical and cultural perspectives.

   To start with, it is important to remember that the nature of agriculture has changed markedly throughout history, and will continue to do so. Medieval agriculture in northern Europe fed, clothed and sheltered a popularly rural society with a much lower population density than it is today. It had smallest effect on biodiversity, and any pollution it caused was typically localized. In terms of energy use and the nutrients captured in the product it was relatively inefficient.

   Contrast this with farming since the start of the industrial revolution. Competition from overseas led farmers to specialize and increase yields. Throughout this period food became cheaper, safer and more reliable. However, these changes have also led to habitat loss and to decreasing biodiversity.

   What’s more, demand for animal products in developing countries is growing so fast that meeting it will require an extra 300 million tons of grain a year by 2050.yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions.

   All this means that agriculture in the 21st century will have to be very different from how it was in the 20th. This will require complete thinking. For example, we need to move away from the idea that traditional practices are unavoidably more sustainable than new ones. We also need to abandon the idea that agriculture can be “zero impact”. The key will be to abandon the rather simple and unchangeable measures of sustainability, which centre on the need to maintain production without increasing damage.

   Instead we need a more dynamic explanation, one that looks at the pros and cons of all the various way land is used. There are many different ways to measure agricultural performance besides food yield: energy use, environmental costs, water purity, carbon footprint and biodiversity. It is clear, for example, that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting. But we do not know whether lower carbon footprints will always be better for biodiversity.

   What is critical is recognizing that sustainable agriculture is not just about sustainable food production.

1.How do people often measure progress in agriculture?

A．By its productivity.               

B．By its impact on the environment.

C．By its sustainability.               

D．By its contribution to economic growth.

2.What does the author think of traditional farming practices?

　　A．They have remained the same over the centuries.

　　B．They have not kept pace with population growth.

　　C．They are not necessarily sustainable.

　　D．They are environmentally friendly.

3.What will agriculture be like in the 21st century?

　　A．It will go through thorough changes.

　　B．It will supply more animal products.

　　C．It will abandon traditional farming practices.

　　D．It will cause zero damage to the environment.

4.What is the author’s purpose in writing this passage?

　　A．To remind people of the need of sustainable development.

　　B．To suggest ways of ensuring sustainable food production.

　　C．To advance new criteria for measuring farming progress.

　　D．To urge people to rethink what sustainable agriculture is.
