阅读理解 The rolling out of 5G services has triggered a wave of competition across the world. More importantly, it has started a race to develop 6G as the telecommunications sector has always been a hotspot for competition. Compared with 5G technology, 6G will have lower latency, higher speed and more bandwidth. And this advanced technology will help connect the real world with virtual digital world. It will also make product design R&D(Research and development) and experiments significantly more efficient and greatly reduce their costs while making it possible to produce digital products. In the physical world through high-tech, including 3D printing. The seamless and intelligent connection of the physical and digital worlds will lead to a thorough reconstruction of the division of labor and societal cooperation. In terms of economic development, 3G fostered e-commerce while 4G boosted e-commerce and mobile payment. 5G infrastructure building and application marked the beginning of intelligent manufacturing. Similarly, wireless cognition technology associated with 6G technology, once it matures, will further boost the development of the digital economy. In digital economy, intelligence based on big data will become the real force for innovation and 6G networks not only will be highways for transmitting data, but will also much more seamlessly integrate edge and core computing as part of a combined communications. This will provide many potential advantages as 6G technology becomes operational, including access to AI capabilities. Digital economy based on 6G will become the determining factor of the country's competitiveness in the future, and 6G technology with wireless cognition as its major characteristic will become core technology and main driver of the digital economy. Starting with 5G our telecom industry, thanks to its extensive R&D input, has taken the lead in standardizing and manufacturing 5G telecom equipment，the competition in 6G will start with the setting of standards, which will determine the level of R&D needed for the launch of the technology and thus decide the market share of the emerging industry . As far as R&D in 5G technology is concerned. We have already enjoyed two advantages. first, it is a global leader in the telecom sector and has a solid reserve of talents. And second, it has a relatively complete industrial chain that covers R&D and design, manufacturing and application. and is home to leading 5G equipment maker. Recent history shows whoever leads the telecom technology sector sets the standards for telecom products and services. and plays a bigger role in the industry's future development . An official research team on 6G including the government. enterprises and research organizations has been established to obtain the advantage of 6G development competition . （1） What does the underlined word "triggered" in paragraph 1 probably mean? A . Put off. B . Kept off. C . Called off. D . Set off. （2） What will the connection of the physical and digital worlds result in? A . Complete changes in the way of work and social cooperation. B . Significant reduction in product design cost and work efficiency. C . Perfect replacement of the virtual digital world to the real world. D . Complete disappearance of work and cooperation in the real world. （3） In the digital economic development, 6G technology will________ A . Become core technology and main driver. B . Mark the beginning of intelligent manufacturing. C . Promote the growth of e-commerce in real world. D . Assist the progress of e-commerce and mobile payment. （4） Which would be the best title for this passage? A . Should we develop 6G in the future? B . If 5G is here, can 6G be far behind? C . Does 6G really have advantages over 5G? D . If developing 6G can we get in a no-win race? 答案： D A A B
