9、 the rate at which artificial intelligence, or AI, is being developed, in the future such dreams may actually come true.At the basic level, artificial intelligence is a branch of computer science that aims to create intelligent machines. One of the essential aims of AI is to develop computer intelli

To achieve this aim, many approaches to creating true AI have been put forward, including “deep learning”, which enables a machine to improve its own performance by learning from the results of its p
11、revious actions.Deep-learning AI has the capacity to analyse massive amounts of data through multiple layers, imitating the complex networks of the human brain.The dream of AI has been around for centuries, and the development of computers since the 1940s has finally made it a reality. Years before
12、the term “artificial intelligence” was coined in the mid-1950s, the theory had been explored by Alan Turing, one of the pioneers in the field of computer science. However, for a long time, AI technology developed very slowly. A major breakthrough in AI came in 1997, when Deep Blue, a chess-playing c

Then in 2017, a computer program named AlphaGo defeated Ke Jie, arguably the best human Go player, which demonstrated a significant advance in deep-learning AI systems.

While AI enthusiasts promise us a bright future where intelligent robots will be working to our advantage, these undoubted benefits also bring concerns and fears. Could machines really develop human-like intelligence? And what would happen if th

74、 use the LiDAR sensors as usual.C. They will continue to explore the unknown.D. They paln to study the documentary carefully.【答案】ADDC【解析】1.本题考察细节理解。在第一段和第二段中，作者向我们列举了LiDAR sensors产生后的重大突破， The ruins of a huge Maya city have been discovered in Guatemala survey landscapes in 3D by bouncing laser pulse
75、s(激光脉冲) off the ground from unmanned air vehicles For instance, major finds at Angkor, Cambodia and Caracol, Belize can explain what it did.这些句子都向我们举例说明了LiDAR sensors的好处，故选A。2.本题考察代词指代。根据划线词的上下文内容可知，隐藏在丛林中的人造景观让专家们重新思考玛雅帝国的轮廓和复杂性，而这些人造景观属于the PACUNAM Foundation, a Maya cultural and natural heritage
76、organization这一组织的发现，故选D。3.本题考察推理判断。根据第三段的 This large lost city envelops sites和最后一段的There are 20,000 square kilometers more to be explored可知，玛雅帝国是广袤的；根据第四段的Hidden under the jungles of the Maya Biosphere Reserve, more than 60,000 human-made featureshomes, canals, highways, some of which can even reach
77、 the modernized standard可知，玛雅帝国达到了现代化的标准，是先进的，故选D。4.本题考察推理判断。根据最后一段中，There are 20,000 square kilometres more to be explored，我们可以推断出，考古学家们还要继续进行新的探索，因为还有20,000平方千米有待开发，故选C。二、应用文写作假定你是李华，星光中学高三学生，你班将举行有关未来职业规划的主题班会。请撰写一份班会发言稿，内容包括:1.各类职业的特点;2.选择职业时的注意事项。注意:1. 词数80左右;2.开头和结尾已给出，不计入总词数。Hello, everyone,A
