“Eat local. ” It’s one way to reduce human effect on the planet. Eating local means to try to buy and consume foods that are grown in places close to home. However, most of the food sold at supermarkets is not locally grown or produced. Trucks and planes deliver these foods from hundreds or thousands of miles away. During the transportation, greenhouse(温室)gases are produced, causing global warming. So the shorter the distance your foods must travel, the less the harm is done to the environment.
But how do you get local food if you live in a large city, hundreds of miles away from farms?Environmental health scientist Dickson Despommier and his students came up with the idea of a “vertical(垂直的) farm”.
A vertical farm is a glass-walled structure that could be built as tall as a skyscraper(摩天大楼). Since the garden is built upwards, rather than outwards, it requires much less space than an ordinary farm. The world is quickly running out of room for ordinary farming. Vertical farms could be a key to this situation. Despommier imagines a 30-story building with a greenhouse on every floor. The walls of the building would be clear, to allow crops to get as much sunlight as possible. Depending on a city’s water resources, Despommier thinks hydroponic(水培的) farming is another method for the vertical farm which needs no soil to grow plants.
Despommier says the hydroponic greenhouses would use a system that would use a city’s waste water and fill it with nutritions to make the crops grow. If this method works, it would provide food to a city and save millions of tons of water.
The idea of a vertical farm has attracted the attention of government officials around the world. Scott Stringer, a government official from New York City, thinks the city is suitable for the vertical farming. “Obviously we don’t have much land left for us,” Stringer said. “But the sky is the limit in Manhattan. ”
Despommier admits that there is still a lot of work to do to make vertical farms a reality. “But I think vertical farming is an idea that can work in a big way,” he says.
1.Why are people advised to eat local?
A. Because it means convenience(方便) to people.
B. Because it can help people save a lot of money.
C. Because local food has more nutrition.
D. Because it is environmentally friendly.
2.Which is one of the vertical farm’s benefits when compared with ordinary farming?
A. It produces healthier food.
B. It does less harm to the cities.
C. It needs less space of the city.
D. It requires less transport costs.
3.By saying “the sky is the limit in Manhattan”, Stringer means _____.
A. people can make full use of vertical space of Manhattan
B. there is a limit for using empty land in Manhattan
C. the height of buildings in Manhattan is limited
D. Manhattan can spread as far as possible

What is the single most effective way to reduce greenhouse-gas emissions? Go vegetarian (素食)? Replant the Amazon? Cycle to work? None of the above. The answer is: make air-conditioners better. On one calculation, replacing refrigerants (制冷剂) damaging the atmosphere would reduce total greenhouse gases equaling 90bn tonnes of CO2 by 2050. Making the units more energy-efficient could double that. By contrast, if half the world’s population gave up meat, it would save 66bn tonnes. Replanting two-thirds of tropical forests would save 61 bn tonnes. A one-third increase in global bicycle journeys, just 2.3bn tonnes.
Air-conditioning is one of the world's great overlooked industries. Automobiles and air-conditioners were invented at roughly the same time, and both have had a huge impact on where people live and Work. Unlike cars, though, air-conditioners have drawn little criticism for their social impact, emissions or energy efficiency. Most hot countries do not have rules to govern their energy use. There is not even a common English word for “coolth” (the opposite of warmth).
Yet air-conditioning has done more than most things to benefit humankind. Lee Kuan Yew, the first prime minister of Singapore, called it “perhaps one of the signal inventions of history”. It has transformed productivity in the tropics(热带地区)and helped turn southern China into the workshop of the World. In Europe, its spread has pushed down heat-related deaths to 10% since 2003, Men 70,000 people than usual, most of them elderly, died in a heatwave. For children, air-conditioned classrooms are associated with better grades at school.
Environmentalists who call air-conditioning“a luxury we cannot afford” have half a point, however. In the next ten years, as many air-conditioners will be installed(安装)around the world as were put in between 1902(invention time)and 2005.Unless energy can be produced without carbon emissions, these extra machines will warm the world. At the moment, therefore, air-conditioners create a vicious cycle. The more the Earth warms, the more people need them. But the more there are, the warmer the world will be.
Cutting the impact of cooling requires three things. First, air-conditioners must become much more efficient. The most energy-efficient models on the market today consume only about one-third as much electricity as average ones, Minimum energy-performance standards need to be raised raised, orintroduced in countries that lack them altogether, to push the average unit's performance closer to the standard of the best.
Next, manufacturers should stop using damaging refrigerants. One type called hydrofluoro-carbons, is over 1,000 times worse than carbon dioxide when it comes to trapping heat in the atmosphere. An international agreement to knock out these pollutants will come into force in 2019.
Last, more could. be done to design offices, malls and even cities so they do not need as many air-conditioners in the first place. More buildings should be built with overhanging roofs orbalconies for shade, or with natural ventilation (自然通风).Simply painting roofs white can help keep temperatures down. Providing indoor air-conditioned comfort need not come at the expense of an overheating world.
1.What’s the most effective way to reduce carbon gases?
A. Planting more trees. B. Leading green lifestyles.
C. Improving cooling systems. D. Buying new air-conditioners.
2.What can we learn from Paragraphs 2 and 3?
A. Air-conditioning enables factories to produce more in hot areas.
B. The heat-related deaths have dropped by 10% since 2003 in Europe.
C. There are many factories producing air-conditioners in southern China.
D. Air-conditioners have received little criticism for they have no negative impact.
3.Why do environmentalists call air-conditioning “a luxury we cannot afford” in Paragraph 4?
A. Because the price of air-conditioning is too high.
B. Because you can’t afford the time for installation.
C. Because the cost of energy consumption is too high.
D. Because the earth will suffer from its carbon emissions.
4.Which of the following measures can reduce the impact of cooling?
a.design natural cooling buildings
b.raise standards for energy-performance
c.make laws for international cooperation
d.stop applying harmful refrigerants to production
A. abc B. abd C. acd D. bed

We were on our way home from Houston one Saturday morning. We decided to stop at a local gas station to get coffee and something to snack on since it was a good hour and a half before we got home.
When we were done, we got back into our car and before I started it, we noticed a man standing outside in front of the building. He was a homeless man with worn clothes and it looked like he had gone in and gotten himself some coffee or something warm to drink since it was cold this time of the year. He must have not had enough money to get something to eat.
Then a dog walked up to the front of the building. I could tell she was a “she”, because you could tell that she had baby dogs. She was terribly in need of something to eat and I felt so bad for her. I knew if she didn’t eat soon, she and her baby dogs would not make it.
I and my wife sat there and looked at her. We noticed that people walked by and didn’t even pet her, like most people do when they walk by an animal in front of a store. We still did not do anything. But the homeless man, who I thought did not buy himself anything to eat, went back into the store. And what he did brought tears to me and my wife. He had gone into the store and with what money he may have had, bought a can of dog food and fed that dog.

To develop one’s taste in English,the most effective way is to read English books extensively. However, one may be at a loss to choose the appropriate books,especially as a beginner.I would like to share some of my experience.
My first English novel was Jane Austen’s Pride and Prejudice,recommended by many English teachers and professors as an ideal book for English learners. But I had great difficulty in understanding the novel,let alone enjoying it. It’s not the vocabulary that troubled me,but rather the way Austen constructs sentences,and her way of thinking,which seemed too remote to me at that time. My fading enthusiasm was much recovered after reading Hemingway’s novel Farewell to Arms. I particularly liked his brief and lively style. So my first suggestion is,as a beginner, you’d better choose contemporary novels instead of classical ones.
However,reading novels is not the only way to improve your English. English essays can at once inform you,entertain you, and improve your taste in English. The best example is Bertrand Russell’s work. Its language is plain, yet you cannot help feeling the elegance and the unique sense of humor. His simple language enables his philosophy(哲理) within the reach of ordinary people. Here comes my second suggestion—essays are indispensable.
Never follow other’s opinions blindly,however famous or influential the person might be. As a saying goes,one man’s meat is another man’s poison. With that in mind,we are sure to find out our favorite writers through reading and develop our fine taste in English.
1.What made the author’s first English novel hard to understand?
A. Complex conversations.
B. Not knowing the social background.
C. The old-fashioned vocabulary.
D. Sentences and Austen’s thinking pattern.
2.Which can best replace the underlined word“ indispensable”?
A. necessary B. challenging
C. related D. inspired
3.What advice does the author give in the last paragraph?
A. Choose books that challenging us most.
B. Read books that are instructive.
C. Don’t be affected by other’s choices.
D. Compare books before buying.
4.What is the author’s purpose of writing the passage?
A. Give comments on literature works.
B. Tell beginners how to choose English books.
C. Encourage people to read more English books.
D. Recommend first-class books to English learners.
