1、精诚凝聚 =_= 成就梦想 高考英语阅读理解专项训练科技类(1)With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). Thats a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project calle
2、d “Noahs Ark”. Noahs Ark is aimed at collecting eggs, embryos(胚胎), semen and DNA of endangered animals and storing them in liquid nitrogen. If certain species should become extinct, Dr. Duane Kraemer, a professor in Texas A & Ms College of Veterinary Medicine, says there would be enough of the basic
3、 building blocks to reintroduce the species in the future. It is estimated that as many as 2, 000 species of mammals, birds reptiles will become extinct in over 100 years.

4、grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit. They are now trying to implant the embryo into a host animal. The entire procedure could take from three to five years to complete. “The nuclear transfer(核子移植) of one species to another is not
5、 easy, and the lack of available(capable of being used) panda eggs could be a major problem,” Kraemer believes. “They will probably have to do several hundred transfers to result in one pregnancy (having a baby). It takes a long time and its difficult, but this could be groundbreaking science if it
6、works. They are certainly not putting any live pandas at risk, so it is worth the effort,” adds Kraemer, who is one of the leaders of the Project at Texas A& M, the first-ever attempt at cloning a dog. “They are trying to do something thats never been done, and this is very similar to our work in No

10、B. scientists try to implant a pandas egg into a rabbit C. Kraemer will work with Chinese scientists in clone researches D. about two thousand of species will probably die out in a century【答案解析】本文讲述中国正在竭力克隆濒临绝种的熊猫，这和Texas A & M University 的Noahs Ark(诺亚方舟)工程极为相似，都是想拯救濒临灭绝的动物。1. B。语义理解题。从第2段内容可知，“诺亚方舟
11、”工程的目标是把濒临灭绝的动物的蛋(卵)、胚胎、精液和DNA储存在液体氮中，如果某一种动物濒临灭绝时，将来可以重现这一动物。2. A。细节题。从第6段第1句话 The nuclear transfer(核子移植) of one species to another is not easy, and the lack of available (capable of being used ) panda eggs could be a major problem 可以做出正确判断。3. C。主旨题。从文章内容来看，无论是中国还是世界克隆熊猫还没有成功，所以排除A、B项；D项内容明显与文章内容不符
12、，故排除。所以“探索克隆熊猫的可能性”应该是这篇文章的标题。4. D。判断题。此题B项的干扰性较强，但由于它没有说明是Chinese scientists，所以应排除。A、C项明显与原文不符。根据文章第3段第1句可知答案非D莫属。(2)Want a glance of the future of health care?

Increasingly, however, remote diagnosis(远程诊断) will be based on real physiological data(生理数据) from the actual patient. A g
14、roup from the University of Kentucky has shown that by using personal data assistance plus a mobile phone, it is perfectly practical to send a patients important signs over the telephone. With this kind of equipment, the cry asking whether there was a doctor in the house could well be a thing of the
15、 past. Other medical technology groups are working on applying telemedicine to rural(countryside) care. And at least one team wants to use telemedicine as a tool for disaster needespecially after earthquakes. On the whole, the trend is towards providing global access to medical data and experts opin
16、ions. But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex(复杂的) medical pictures around the world CT photos being one of the biggest bandwidth users. Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars. But medicine is looking towards both the
