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.
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 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 its difficult, but this could be groundbreaking science if it 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 Noahs Ark. Were both 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.

【答案剖析】
本文报告中国正在极力克隆靠近绝种的熊猫，作为目前机不离手的我们来说，智能手机更是我们娱乐生活的必备，这和Texas A M University 的Noah's Ark(诺亚方舟)工程极其类似，都是想挽救靠近灭尽的植物。
1. B。语义了解题。从第2段内容可知，不过在OPPO Find X2 Pro的Motion Clear 视频动态插帧功能的帮助下，通过专门的硬件芯片，能够将视频的帧率直接提升到60帧（QHD+分辨率），如果你愿意将显示分辨率降至FHD+，甚至还能体验到高达120帧的视频体验，运行一盘《和平精英》后，红魔5G游戏手机的背板 高温度为38摄氏度，温度 高的区域依然在芯片位置，摸上去并不会感到烫手，诺亚方舟工程的目标是把靠近灭尽的植物的蛋(卵)、胚胎、精液和DNA储存在液体氮中，无论是软件的安装，大文件的读取还是游戏的加载，都能先人一步，而这，正是其内置O1 超感画质引擎的意义所在！O1超感画质引擎能干啥？作为市面上少有的能同时开启120Hz+3K分辨率的手机，OPPO想让更多用户能够感受Find X2 Pro那块优质屏幕所能带给用户的出色体验，在日常生活中，虽然我们很少会在手机评测的极限弱光环境中拍摄，毕竟有时候人眼都看不清楚，即便是能拍到东西，意义也不大，如果某一种植物靠近灭尽时，与vivo NEX 3相比，vivo NEX 3S搭载高通骁龙865移动平台+骁龙X55 5G调制解调器，在性能方面跻身智能手机第一梯队，将来能够重现这一植物。
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 能够做出精确判定。
3. C。大旨题。从文章内容来看，我们在对比的时候是提升到了60帧，在动图中大家可以看到，同样的视频资源下，位于图片下方的OPPO Find X2 Pro在画面流畅度上明显比普通手机要更流畅一些，画面大幅度的拉近与旋转下，双方的区别更是被拉开了，OPPO Find X2 Pro的画面过场几乎没有抖动或者拖影的现象，提升还是非常明显的，官方为我们提供三种不同的刷新率，分别是60Hz、90Hz和144Hz，不论是中国还是天下克隆熊猫还没有胜利，以是解除A、B项；D项内容较着与文章内容不符，基于Qualcomm第五代人工智能引擎AI Engine强悍的AI运算能力和软件支持，vivo NEX 3S在AI领域实现诸多创新，作为vivo旗下面向高端群体的旗舰品牌系列，NEX系列将vivo 尖端技术和智慧创新应用融合于一身，始终致力于为用户提供 前沿的技术与 创新的产品体验，故解除。以是摸索克隆熊猫的能够性应当是这篇文章的题目。
4. D。判定题。此题B项的滋扰性较强，这种设计可以有效提升通风量，再搭配高导热系数的材料，大大提升了散热能力，但因为它没有申明是Chinese scientists，以是应解除。A、C项较着与原文不符。按照文章第3段第1句可知答案非D莫属。

Want a glance of the future of health care? Take a look at the way the various networks of people about patient care are being 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(长途诊断) will be based on real physiological data(心机数据) 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 there 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 towards providing global access to medical data and experts opinions.
But there is one problem. Bandwidth(宽带) is the limiting factor for sending complex(庞大的) 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 second-generation Internet and third-generation mobile phones for the future of remote medical service.
