BBC News (May 11, 2008) —Edinburgh Zoo plans to bring a pair of giant pandas from China to Scotland. Representatives from Edinburgh Zoo have recently returned from China. They signed a letter of intent (意向书) there, making a promise to bring giant pandas to the Zoo.
It has been suggested that the pair of giant pandas should be on loan (暂借) to the Royal Zoological Society of Scotland (RZSS) for 10 years. The pair of giant pandas would give birth to babies during that time. Edinburgh Zoo would be the eighth zoo in the Western world to care for the species if the project goes ahead.
Zoo chiefs said that looking after the endangered animals could benefit conservation. David Windmill, chief of RZSS, said, "Working with giant pandas means so much more to us than introducing a new species to our collection. It is an opportunity to work on a global level with other conservationists to gain a better understanding of the giant pandas, the threats they face, and what we can do to ensure their survival."
At present, there are only around 1,500 giant pandas in the wild. RZSS has been working on the project for almost a year, hoping to have giant pandas at Edinburgh Zoo by 2009, the year of the society’s centenary (一百周年纪念日). Mr. Windmill said that the project has received strong support from the UK and Scottish Governments. He also said that this must continue if the Zoo is to reach an agreement with the Chinese. As part of the agreement with the Chinese Government, Edinburgh Zoo will work together with Chinese scientists on research projects benefiting conservation in the wild.
RZSS will also provide money to support giant panda conservation projects in the wild. Giant pandas live in mountainous regions in central China and almost mainly feed on bamboo, which makes up 99% of what they eat.
57. What do we know from the first two paragraphs?
A. China will give a pair of giant pandas to Edinburgh Zoo.
B. Representatives from Edinburgh Zoo have been to China.
C. The Scottish Government has signed a letter of intent with China.
D. Edinburgh Zoo is the first Western zoo to have giant pandas.
58. According to the text, RZSS may be ___________.
A. a company that deals with international business
B. an organization that researches endangered animals
C. a government department in charge of Western issues
D. an activity having something to do with animals
59. We can know from the text that _____________.
A. David Windmill is Edinburgh Zoo’s chief
B. the number of giant pandas in the wild is still unknown
C. RZSS will celebrate its centenary in 2009
D. RZSS knows the threats the giant pandas face well
60. What’s the main idea of the text?
A. Edinburgh Zoo expects giant pandas from China.

Climate has been a major driver of armed conflict in Africa, research shows—and future warming is likely to increase the number of deaths from war. US researchers found that across the continent, conflict was about 50% more likely in unusually warm years.
Writing in Proceedings of the National Academy of Sciences (PNAS), they suggest conflict arises when the food supply is not enough in warm conditions. Climatic factors have been mentioned as a reason for several recent conflicts. One is the fighting in Darfur in Sudan that has killed 200,000 people and forced two million more from their homes. Previous research has shown an association between lack of rain and conflict, but this is thought to be the first clear evidence of a temperature link.
The researchers used databases of temperatures across sub-Saharan Africa for the period between 1981 and 2002, and looked for connections between above average warmth and civil conflict in the same country that left at least 1,000 people dead. "Studies show that crop output in the region is really sensitive to small shifts in temperature, even of half a degree or so," research leader Marshall Burke, from the University of California at Berkeley, told BBC News.
"Our findings provide strong motivation to increase investments in African adaptation to climate change by such steps as developing crop varieties less sensitive to extreme heat and promoting insurance plans to help protect farmers from negative effects of the hotter climate," said Dr Burke. "If the argument is that the trend towards rising temperatures will increase conflict, then we need to do something around climate change, but more fundamentally we need to resolve the conflicts in the first place."
If the sub-Saharan climate continues to warm and little is done to help its countries better adapt to high temperatures, the human costs are likely to be unimaginable. If temperatures rise across the continent as computer models project, future conflicts are likely to become more common, researchers suggest. Their study shows an increase of about 50% over the next 20 years.
When projections of social trends such as population increase and economic development were included in their model of a future Africa, temperature rise still emerged as a likely major cause of increasing armed conflict. At next month's UN climate summit (峰会) in Copenhagen, governments are due to debate how much money to put into helping African countries prepare for and adapt to negative effects of climate change.
57.According to the passage, which of the following is one of the reasons for the fighting in Darfur in Sudan?
A.Shortage of drinking water.                         B.Racial discrimination.
C.Rising temperature.                                     D.Demand for planting land.
58.What can we know from the research done by the US researchers?
A.There is no close relation between rainfall and conflict.
B.Temperature greatly affects crop production in sub-Saharan Africa.
C.Temperature will rise by about 50% in Africa over the next two decades.
D.With world cooperation, conflicts in Africa will be reduced by half 20 years later.
59.What can be inferred from the passage?
A.Something must be done to help sub-Saharan countries with better adaptation to climate change to avoid disaster.
B.Conflicts in sub-Saharan countries are sure to be on the rise in future.
C.Temperature in sub-Saharan countries will rise at a faster speed.
D.High temperatures will make sub-Saharan countries unfit to live in.
60.What's the best title for this passage?
A.World cooperation against African conflict
B.Africa's sufferings from climate change
C.Food shortages lead to African conflict
D.Climate drives African conflict

Scientists have not come close to understanding all the different kinds of life on the planet, but US researcher Craig Venter is already working on creating the first artificial life.
Venter and his researchers made a breakthrough this August. They successfully moved the DNA of one type of bacteria(细菌) to a yeast(酵母) cell, changed it, then put it into another bacterial cell.
“Bacteria have systems that protect them from foreign DNA,” Venter explained to the BBC. In the experiment, the team managed to block this system.
The experiment was performed on a simple type of bacteria called Mycoplasma mycoides. The team took the bacteria’s genes and put them into a yeast cell.
Putting the DNA in a yeast cell allowed the team to change the genes----in this case, taking out a gene that was not necessary for the bacteria to live.
They then put the gene into a host bacteria cell. The cell went on to divide normally, producing new healthy bacteria.
In January, the team created artificial genes of a new type of bacteria. Their next goal is to put the artificial DNA into a host cell to create a new species, according to a report in Science magazine.
“If we don’t make any errors, I think it should work and we should have the first artificial species by the end of the year,” Venter said in the report.
The first artificial life from is likely to be a simple man-made bacteria, to prove that the technology can work. But that form will be followed by more complex bacteria that turn coal into cleaner natural gas, or algae that can take in carbon dioxide and change it into fuel.
Many scientists think it’s good news to have this artificial life, but others are worried that the technology to create new organisms might end up in the wrong hands, with dangerous results.
【小题1】Craig Venter and his team are working to ______.

A.create a new animal
B.clone a new species
C.produce the first artificial bacteria
D.develop a new system
【小题2】Which of the following is the right order of the experiment?
