Computers are very important to modern life. Many people think that in the future computers will be used in lots of everyday life. It is thought that we won’t have to go shopping because we will be able to get most things which are sold in shops on the Internet. There will be no more books because we will be able to get all texts from computers. The Internet will be used to play games, see films and buy food. Most telephone calls will be made by computers, too.

Some people are glad about these new ways of shopping and communicating. Others do not think that computers will replace our old ways.

Let’s look at books, for example. Some people think that one day we will not read books made of paper. Instead, we will buy and read books using computers. We will read texts on small pocket computers. The computers will keep many different books in them at the same time. We won’t need to turn lots of pages and paper will be saved. Computerized(计算机化) books will be used more and more.

Is Internet shopping such a pleasure as going to the shop? Many people say it is not. It is a pleasure to go into shops and look at things you want to buy. It is also unlikely that many people will want to read large texts on our computers. Because paper books will perhaps be more friendly. Maybe computers won’t change these two habits.

In paragraph(段落)1 it is thought people will use computers for _______.

A. playing games, shopping and making telephone calls

B. making telephone calls, having meals and seeing films

C. seeing films, buying food, and going for holidays

D. playing games, making telephone calls and seeing the doctor

Which reason for using computerized books is NOT said in the passage?

A. Computerized books won’t be very expensive.

B. Computers can keep many different books in them.

C. We won’t have lots of pages.

D. We won’t need any paper.

Paragraph 4 tells _______.

A. about the old and new ways of shopping and communicating

B. if the Internet will change our habits

C. about computerized books

D. about future uses of computers

The title for this passage is _______.

A. Computers will Replace Shops and Books B. Computers will be Used a lot in the Future

C. Computers will Do Everything for Man D. How Computers Change Our Habits

According to the writer’s view, which is right?

A. Computers will replace everything completely in our daily life in the future.

B. Computers will not be used at all in our daily life in the future.

C. Computers will not be used in shopping in the future.

D. Computers will bring more and wider usage in our daily life in the future.

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 21^st 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.

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.

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.

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.

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.

Microwaves may be great at warming up food, but what about warming people?

Using microwaves to directly heat owners of a room would save much of the energy wasted by heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe, according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire. Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is about 0.2 inches, for example) and with no negative effects.

To test this idea, Buffler subjected himself to microwaves in a special room using a standard 500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20 kilowatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and 50 mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85 mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.

In houses of the future, each room could be provided with its own magnetron, says Buffler. When you stepped into the living room, for example, a motion detector (运动感应器)would turn on the magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the temperature of your coffee table. (You could, however, make your favorite easy chair even more comfortable by treating it with a radiation-absorbing chemical.)

While it might be some time before homeowners are comfortable enough with the idea to set up whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers. Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm the lambs safely and quickly.

Which of the following can tell the main idea of the passage?

A. A new heating system.

B. A new microwave oven.

C. A popular technique.

D. The magnetron.

According to Paragraph 2, which of the following does not describe the characteristics of a microwave heater?

A. It directly heats people in a room.

B. It heats walls and furniture in a room.

C. It is safe.

D. It saves energy．

The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about ________________.

A. 20 mw. / sq. cm. B. 40 mw. / sq. cm.

C. 60 mw. / sq. cm. D. 85 mw. / sq. cm.

According to Paragraph 4, which of the following fills the room with low-power microwaves?

A. The magnetron.

B. The motion detector.

C. The microwave oven.

D. The radiation-absorbing chemical.

Which of the following statements about microwave heaters would Buffler most probably agree with?

A. Microwave heaters will soon be widely used by homeowners.

B. Microwave heaters sometimes make people feel uncomfortable.

C. Perhaps microwave heaters will be first used by livestock farmers, who wish to protect their lambs in winter.

D. Microwave heaters cannot be accepted by the public because they are somewhat unsafe.

At an airport I overheard a father and daughter in their last moments together．They had announced her 54 ’s departure．Standing near the door, he said to his daughter: “I love you, I wish you 55 ．” She said: “Daddy, our life together has been more than enough．Your love is all I ever needed．I wish you enough, too, Daddy．” They kissed good-bye and she left．

He walked 56 toward the window where I was seated．I tried not to intrude （侵犯） on his 57 , but he welcomed me in by asking: “Did you ever say good-bye to 58 knowing it would be forever?” “Yes, I have,” I replied．“ 59 me for asking, but why is this a forever good-bye?” I asked．“I am old and she lives much too far away．I have 60 ahead and the reality is, her next trip back will be for my funeral,” he said．“When you were saying good-bye I heard you say, ‘I wish you enough．'' May I ask what that means?”

He began to smile．“That is a wish that has been handed down from other 61 ．My parents used to say it to everyone．” He paused for a moment, looking up as if trying to remember it in detail, he 62 even more．“When we said ‘I wish you enough'', we wanted the other person to have a life filled with enough good things to sustain them,” he continued and then 63 toward me, he shared the following 64 he were reciting it from memory．

“I wish you enough sun to keep your attitude 65 ．I wish you enough rain to appreciate the sun more．I wish you enough happiness to keep your spirit alive．I wish you enough pain so that the 66 joys in life appear much bigger．I wish you enough gain to satisfy your 67 ．I wish you enough loss to appreciate all that you 68 ．I wish enough “Hello”s to get you 69 the final “Good-bye．” He then began to sob （哽咽） and walked away．

It is said that “It takes a/an 70 to find a special person, an hour to 71 them, a day to love them, 72 then an entire life to 73 them．”
