In a world with limited land, water and other natural resources, the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil， which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emission (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate (加速) the change from traditional model to a sustainable one.

The major challenge of this century is to find ways to meet the needs of growing population within the limits of this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

1. The traditional business model is harmful because of all the following EXCEPT that ______.

A. it makes the world warmer

B. it consumes natural resources

C. it brings severe damage to forests

D. it makes growth hard to continue

2.What can we infer from Paragraph 2?

A. China lacks wind and solar energy.

B. China is the leader of the low carbon market.

C. High speed trains are a low carbon development.

D. Palm oil is made at the cost of valuable forests.

3.To fully develop the low carbon markets, government can ______.

A. cut public expenses B. forbid carbon emission

C. develop public resources D. encourage energy conservation

4.We can learn from the last paragraph that businesses have many chances to ______.

A. develop sustainable products

B. explore new natural resources

C. make full use of natural resources

D. deal with the major challenge

5.What is the main purpose of the passage?

A. To introduce a new business model.

B. To compare two business models.

C. To predict a change of the global market.

D. To advocate (提倡) sustainable development.

Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.

Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.

“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.

The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.

“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近亲交配) problems ... and at the end these species may disappear,” he added.

Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.

The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.

Other consequences could include the spread of invasive species and infectious diseases, it said.

The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(红树林), inland waters, forests, savannahs(非洲大草原) and grasslands.

The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.

The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.

It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.

1.What does the author tell us in Paragraph 2?

A．The theme of global climate negotiations in Durban.

B．The subject of research done by Eduardo Rojas.

C．Causes of damage done to ecosystems.

D．Harmful effects of damage done to ecosystems.

2.Why are animals living in mountains, islands and coastal areas most affected?

A．They are frequently attacked by invasive species and infectious diseases.

B．They have difficulty finding enough food for survival.

C．They can hardly find mates to produce their young.

D．They have little chance of moving to other places.

3.To avoid extinction of some animal species, the UNFAO suggested all the following ways EXCEPT ______.

A．restoring damaged ecosystems

B．limiting world population growth

C．creating movement channels for animals

D．urging governments and local communities to take action

4.What does the underlined word “mitigate” in the last paragraph mean?

A．increase or further improve something.

B．Make full use of something.

C．Make something become less serious.

D．Move from one place to another.

5.What would serve as the best title for the passage?

A．Animals at risk due to climate change.

B．Global warming and its consequences.

C．Climate change and ecotourism.

D．Solutions to animal distinction.

CORVALIJS. Ore.-- Engineers at Oregon Suite University have made a breakthrough in the performance of microbial (微生物的)fuel cells that can produce electricity directly from wastewater，opening the door to a future in which waste treatment plants not only will power themselves, but will sell extra electricity.

The new technology ,developed at OSU, can now produce 10 to 50 more times the electricity, per volume, than most oilier approaches using microbial fuel cells,and 100 times more electricity than some.

Researchers say this could eventually change the way that wastewater is treated all over the world, replacing the widely used “activated sludge (泥浆) ” process that has been in use for almost a century. The new approach would produce significant amounts of electricity while effectively cleaning the wastewater,

“If this technology works on a commercial scale the way we believe it will ,the treatment of wastewater could be a huge energy producer, not a huge energy cost.” said Hong Liu ，an associate professor in the OSU Department of Biological and Ecological Engineering. “This could have an impact around the world, save a great deal of money, provide better water treatment and promote energy sustainability.”

The biodegradable (能降解的）characteristics of wastewater, if developed to their full potential, could theoretically provide many times the energy that is now being used to process them, with no additional greenhouse emissions.

OSU researchers reported several years ago on the promise of this technology, but at that time the systems in use produced far less electrical power. With new concepts, the technology can now produce more than two kilowatts per cubic meter of liquid reactor volume.

The new system also works better than an alternative approach to creating electricity from wastewater, based on anacrobic (臭氧的）digestion that produces methane (甲烷）.It treats the wastewater more effectively, and doesn’t have any of the environmental drawbacks of that technology, such as production of possible release of methane, a significant greenhouse gas.

1.Which of the following best expresses the main idea of the passage?

A．The treatment of wastewater is a huge energy cost.

B．Wastewater is being treated differently over the world.

C．Waste treatment plants have found a new way to power themselves.

D．Microbial fuel cells will produce more electricity from wastewater.

2.What can we learn about the new technology from the passage?

A．It can produce 100 times more electricity than any approach used today.

B．Through it more electricity can be created and water can be cleaned better.

C．It has already changed the way that wastewater is treated all over the world

D．It has opened the door to put microbial fuel cells to productive use.

3.What attitude does Professor Liu hold towards the new technology?

A. Supportive. B. Critical. C Unconcerned. D. Curious.

4.According to the last paragraph, why does the new system work better than the alternative approach?

A．Because it is co-friendly and treats wastewater more effectively.

B．Because it can make full use of anaerobic digestion producing methane.

C．Because it may produce less methane than the alternative approach.

D．Because it can produce 10 times the energy than the alternative approach.

Daniel stays home on workdays. He starts his personal computer in order to connect with the office which is about three hundred miles away in another city. After work, he puts on his headphones, watches a movie on his home video recorder, or plays baseball on the computer. On many days, Daniel doesn’t talk to any other human beings, and he doesn’t see any people except the ones on television. Daniel is imaginary, but his lifestyle is very possible. The inventions of modern technology seem to be cutting us off from contact with our fellow human beings.

The world of business is one area in which technology is separating us. Experts say, for example, that many people will soon be able to work at home. With access to a large central computer, employees such as office clerks, insurance agents, and accountants could do their jobs at display terminals (终端) in their own homes. They would never have to actually see the people they’re dealing with. In addition, the way employees are paid will change. Workers’ salaries will be automatically paid into their bank accounts, making paper checks unnecessary. No workers will stand in line to receive their pay or cash their checks. Personal banking will change, too. Customers will deal with machines to put in or take out money from their accounts. Many companies and consumers have already changed the way they sell or buy products. E-commerce, or business done on the Internet, is becoming more and more popular. This, therefore, makes it possible for people to do shopping without going out of their homes.

Another area that technology is changing is entertainment. Music, for example, was once a group experience. People listened to music at concert halls or in small social gatherings. For many people now, however, music is an individual experience. Walking along the street or sitting in their living-rooms, they wear headphones to build a wall of music around them. Movie entertainment is changing as well. Movies used to be social events. Now, fewer people are going out to see a movie. Many more are choosing to wait for a film to appear on television or are borrowing videotapes to watch at home. Instead of laughing with others, viewers watch movies in their own living-rooms.

1.After work, Daniel likes to ______.

A. listen to music at the concert hall B. watch a movie in his living-room

C. chat with his friends on the net D. play baseball with his workmates

2.The underlined sentence “Daniel is imaginary, but his lifestyle is very possible” means ______.

A. Daniel is a person full of imagination and he can make his life colorful.

B. Daniel is not a real person but the lifestyle of his kind does exist.

C. Daniel is only an ordinary person but he has his own way of living.

D. Daniel is a model who makes full use of modern technology in life.

3. What will the writer most probably discuss after the last paragraph?

A. Games and sports B. Personal banking

C. Music and films D. International business

4.What is the main idea of the passage?

A. We may no longer need to communicate with other human beings.

B. Modern technology seems to be separating human beings.

C. We may no longer need to work in the office.

D. Modern technology makes it possible for us to work and entertain ourselves at home.
