Though much effort and many resources have been spent on protecting the endangered giant panda, research by an international team of scientists shows that much suitable panda habitat is outside the nature reserves and areas where the panda is reported to live.

“This research can help the Chinese government and international nongovernmental organizations develop full strategic(战略上的) plans for more effective conservation of the panda,” said Jianguo “Jack” Liu, MSU University Distinguished Professor of fisheries and wildlife.

“Overall, about 40 percent of the suitable habitat for pandas is inside the nature reserves,” said Andres Vina, a specialist. “But we have also identified potentially suitable habitat outside the reserves.”

The giant panda is the rarest member of the bear family. Pandas once ranged throughout most of China, northern Vietnam and northern Myanmar. Today, fewer than 1,600 giant pandas live in the wild in three Chinese provinces; Gansu, Shanxi and Sichuan. Human actions—including logging(伐木), residential development and the expansion of farming—are considered the main reasons for the dramatic decrease of the giant panda’s habitat.

The research team developed habitat models using geographical and environmental information gathered by satellites overlaid with information on panda occurrence. After analyzing six mountain regions in the three provinces where pandas are known to live, the scientists developed a habitat suitability index(索引) for the entire 48,328 square-mile area. The range-wide habitat analysis model gives the government and other agencies a new tool as they develop conservation strategies not only for pandas but also for many other endangered species.

“The Chinese government plans to add about 69,500 square miles of land to the country’s nature reserve system between 2010 and 2020,” said Zhiyun Ouyang, director of the Lab of Urban and Regional Erology at the Chinese Academy of Sciences in Beijing. “So opportunities exist to create new reserves, to expand existing reserves and to create pathways that increase the connectivity among the reserves. On the basis of our results, we suggest some new areas be included in China’s nature reserve system.”

66．Which of the following is NOT true?

A．China has made lots of efforts to protect the giant panda.

B．Pandas live better only outside the nature reserves.

C．More plans should be created to protect the giant pandas.

D．Liu Jianguo is a professor who devotes himself to fisheries and wildlife.

67．According to the passage, the giant pandas .

A．have the same living habit as bears

B．are only suitable to live in Gansu, Shanxi and Sichuan

C．will all be protected in the nature reserves

D．are endangered mainly due to the damage to their habitat

68．The purpose of developing habitat models is .

A．to know where pandas actually live in China

B．to build a larger nature reserve for the pandas

C．to develop conservation strategies for endangered species

D．to give governments a warning

69．The underlined word “overlaid” in the fifth paragraph probably means “ ”.

A．covered B．connected C．coped D．varied

70．What can we learn from the last paragraph?

A．Zhiyun Ouyang hopes more areas will become nature reserves in China.

B．China has about 69,500 square miles of nature reserves now.

C．The existing reserves will remain the same.

D．The existing reserves shouldn’t be expanded.

With petroleum reserves (石油储量) decreasing, the search is on to replace gas with a cleaner，greener alternative. Though much eco－talk has centered on biofuels from corn and soybeans, the biofuel that looks more likely to replace petroleum comes from a most unlikely source: algae(藻类)．

Algae, like corn, soybeans, and other crops, grow via photosynthesis(光合作用) and can be processed into fuel oil. However, they yield 30 times more energy than land crops such as soybeans, according to the U．S. Department of Energy. Many algae species also can grow in saltwater and polluted water—while corn and soy require arable land and fresh water that will be in short supply as the world's population balloons.

“If you replaced all the diesel(柴油) in the U．S. with soy biodiesel, it would take half the land mass of the U．S. to grow those soybeans，” says Matt Caspari, chief executive of Aurora Biofuels, a Berkeley, Calif－based private firm that specializes in algae oil technology. On the other hand, the Energy Department says that if algae fuel replaced all the petroleum fuel in the United States, it would require 15,000 square miles, which is a few thousand miles larger than Maryland (12,407 square miles), the 42nd state in land area.

Another bonus: Because algae can be grown just about anywhere in a closed space, they're being tested at several power plants across the nation as a carbon absorber. Smokestack emissions (烟囱排放物) can be pumped directly into the ponds, feeding the algae while keeping greenhouse gases out of the atmosphere.

Although processing technology for algae fuel－also known as “oilgae” in some environmentalist circles—is improving, it's still years away from reaching your local gas pump. “It's just a question of cost, because no large－scale facilities have been built yet，” Caspari says.

3. According to Paragraph 3, one of the advantages of algae fuel is that________.

A. it can be used more widely

B. it is more easy to produce

C. it needs much less land

D. it costs much less money

4. What do we learn about algae from Paragraph 4?

A. Algae help protect the environment.

B. People can grow algae anywhere.

C. Fish can get more oxygen from algae.

D. Algae produce less waste.

5. What does the passage mainly talk about?

A. Environmental protection.

B. Biofuels from corn and soybeans.

C. The false hope of biofuels.

D. A promising oil alternative.
