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). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five ye ars in a project called “Noah’s Ark”.Noah’s 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 & M’s C ollege of V eterinary Medicine, says there would be enough of the basic 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. 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 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 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 it’s difficult, but this could be groundbreaking science if it works. They are certainly not putting any live pa ndas 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 that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”1. The aim of “Noah’s Ark” project is to _______.A. make efforts to clone the endangered pandasB. save endangered animals 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 eggsB. host animalsC. qualified researchersD. enough money3. The best title for the passage may be _______.A. China’s Success in Pandas CloningB. The First Cloned Panda in the WorldC. Exploring the Possibility to Clone PandasD. China —the Native Place of Pandas Forever4. From the passage we know that _______.A. Kraemer and his team have succeeded in cloning a dogB. scientists try to implant a panda’s egg into a rabbitC. Kraemer will work with Chinese scientists in clone researchesD. about two thousand of species will probably die out in a century【答案与解析】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Noah's Ark(诺亚方舟)工程极为相似，都是想拯救濒临灭绝的动物。
高三现代科技前沿探索英语阅读理解20题1<背景文章>Artificial intelligence (AI) is rapidly transforming the field of healthcare. In recent years, AI has made significant progress in various aspects of medical care, bringing new opportunities and challenges.One of the major applications of AI in healthcare is in disease diagnosis. AI-powered systems can analyze large amounts of medical data, such as medical images and patient records, to detect diseases at an early stage. For example, deep learning algorithms can accurately identify tumors in medical images, helping doctors make more accurate diagnoses.Another area where AI is making a big impact is in drug discovery. By analyzing vast amounts of biological data, AI can help researchers identify potential drug targets and design new drugs more efficiently. This can significantly shorten the time and cost of drug development.AI also has the potential to improve patient care by providing personalized treatment plans. Based on a patient's genetic information, medical history, and other factors, AI can recommend the most appropriate treatment options.However, the application of AI in healthcare also faces some challenges. One of the main concerns is data privacy and security. Medicaldata is highly sensitive, and ensuring its protection is crucial. Another challenge is the lack of transparency in AI algorithms. Doctors and patients need to understand how AI makes decisions in order to trust its recommendations.In conclusion, while AI holds great promise for improving healthcare, it also poses significant challenges that need to be addressed.1. What is one of the major applications of AI in healthcare?A. Disease prevention.B. Disease diagnosis.C. Health maintenance.D. Medical education.答案：B。

LampbrellaYou can’t always predict a heavy rain or remember your umbrella. ①But designer Mikhail Belvacv doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet. That’s why he created lampbrella, a lamp post with its own rain sensing umbrella.The designer says he ②come up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street ad saw the street lamps ③lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy built into a street lamp.”he said.The lampbrella is a standard-looking street lamp fitted with an umbrella canopy. It has a built-in electric motor which can open or close the umbrella ④on demand. Sensors then ensure that the umbrella offers p edestrians shelter whenever it starts raining.⑤In addition to the rain sensor, there’s also a 360°motion sensor on the fiberglass street lamp which detects whether anyone’s using the lampbrella. After three minutes of not being used the canopy is closed.According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation one Moscow Department, and insists this creation could be installed on my street where a lot of people walk but there are no canopies toprovide shelter.灯柱伞你不会每次都预测到大雨到来或者记得带上雨伞。
