阅读理解 Researchers from the universities of Istanbul and Hawaii hope the technique can lead to new ways to produce medicines.
As part of an effort to improve treatments for life-threatening illnesses, a team of scientists have created rabbits that glow in the dark. Their efforts produced two rabbits out of a litter of eight that went from being a normal, fluffy white to glowing green in the dark. The rabbits were born at the University of Istanbul as part of a collaboration between scientists from universities in Turkey and Hawaii.
The rabbits glow to show that a genetic manipulation technique can work efficiently, though the specific color is more cosmetic than scientific.
"The green is not important at all—it's just a marker to show the experiment can be done successfully," said University of Hawaii associate professor Stefan Moisyadi.
To produce the glowing effect, researchers injected jellyfish DNA into a mother rabbit's embryos. Those altered embryos were then inserted back into the mother. Similar experiments have resulted in glowing cockroaches and cats.
Eventually, the researchers hope the technique can lead to new ways to produce medicines, Moisyadi said. "The final goal is to develop animals that act as barrier reactives to produce beneficial molecules in their milk that can be cheaply extracted, especially in countries that can not afford big pharma plants that make drugs, that usually cost $ 1 billion to build, and be able to produce their own protein-based medication in animals," Moisyadi said.
The rabbits are expected to have the same life span as their non-glowing counterparts, but Moisyadi said he understands people can object to this kind of experimentation involving live animals. "To the people against, I say: think about, what are the benefits and what are the injuries?" Moisyadi said. "And if the benefits outweigh the injuries, let's go with the benefits."
Moisyadi, a native of Turkey who is now with the University of Hawaii, started developing the project in 2006, and researchers are now waiting to see if pregnant sheep produce similar results.
单选题 6.Which is the final goal of the researchers and scholars by breeding rabbits that glow?
【正确答案】 D
【答案解析】推断题。此题考查实验的根本目的。文章第一段即指出…hope the technique can lead to new ways to produce medicines(希望能利用科技手段找到生产药物的新途径),第五段又提到Eventually,the researchers hope the technique can lead to new ways to produce medicines,由此可知D项为正确答案。
单选题 7.The purpose of Moisyadi by saying the words in Paragraph 3 is to show____.
【正确答案】 C
【答案解析】推断题。根据题干关键词定位到第三段。莫伊斯雅迪说“是不是绿色根本不重要,有颜色不过是证明实验能够取得成功的标志”,由此可以推断,只要有颜色,哪种颜色都没问题,因此C项为正确答案。
单选题 8.The underlined phrase "pharma plants" in Paragraph 5 probably means____.
【正确答案】 B
【答案解析】含义题。根据题干关键词定位到第五段。本句为…pharma plants that make drugs…根据定语从句that make drugs就可以推断出pharma plants是“制药厂”的意思,pharma一词与pharmacy意思相通,plant意为“工厂”。因此B项为正确答案。
单选题 9.Why does Moisyadi think some people won't accept this experiment?
【正确答案】 B
【答案解析】细节题。根据关键词定位到第六段。由he understands people can object to this kind of experimentation involving live animals可知正确答案为B项,即人们反对这项实验可能是因为实验涉及活体动物,题干中的won’t accept是对原文object to的同义复现。
单选题 10.Which of the following descriptions is true about Stenfan Moisyadi?
【正确答案】 B
【答案解析】细节题。第五段介绍了莫伊斯雅迪的观点,因此答案应从本段中找,B项说他想帮助那些贫穷的国家发展制药业,这是对第五段的正确概括,为正确答案。
