1、高考英语阅读科技类科技类(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 called “Noahs Ark”. No

2、ahs 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 building blocks

3、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. The panda, native only to China, is in danger of becoming extinct in the next 25 years. This week, Chinese scientists said they grew an embryo by

4、 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 easy, and the la

5、ck 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 works. They are c

6、ertainly 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 Noahs Ark. Were bot

7、h trying to save animals that face extinction. I certainly appreciate their effort and theres a lot we can learn from what they are attempting to do. Its a research that is very much needed.” 1. The aim of “Noahs Ark” project is to _.A. make efforts to clone the endangered pandasB. save endangered a

8、nimals from dying outC. collect DNA of endangered animals to studyD. transfer the nuclear of one animal to another2. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _.A. available panda eggs B. host animalsC. qualified researchers D. enough money3. The best t

9、itle for the passage may be _.A. Chinas Success in Pandas Cloning B. The First Cloned Panda in the World C. Exploring the Possibility to Clone Pandas D. China the Native Place of Pandas Forever4. From the passage we know that _.A. Kraemer and his team have succeeded in cloning a dog B. scientists tr

10、y 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(2) Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are bei

11、ng connected to one another, and how this new connectivity is being exploited to deliver medicine to the patient no matter where he or she may be. Online doctors offering advice based on normal symptoms(症状) are the most obvious example. Increasingly, however, remote diagnosis(远程诊断) will be based on

12、real physiological data(生理数据) from the actual patient. A group 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 th

13、ere was a doctor in the house could well be a thing of the 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 toward

14、s providing global access to medical data and experts opinions. 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-te

15、rm needs during disasters such as earthquakes or wars. But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service. Doctors have met to discuss computer-based tools for medical diagnosis, training and telemedicine. With the falling price of broadband communications, the new technologies should start a new time when telemedicine and the sharing of medical information, experts opinions and diagnosis are common. 1. The writer chiefly talks about _. A. the use of telemedicine B. the on-lined doctors C. me
