问题

右边的漫画将1929—1933年的资本主义经济危机比作笼罩全球的巨大章鱼,形象地反映了经济危机的特点之一是

A.波及范围很广

B.危机一发而不可收

C.股票大量抛售

D.美国成为世界头号强国

答案

答案:A

题目分析:根据题意,结合经济危机的特点来看,此次经济危机范围特别广:从地域范围看,危机从美国蔓延到德,日,英,法等主要资本主义国家,并且波及到殖民地半殖民地和不发达国家,席卷了整个资本主义世界;从经济范围看,危机期间信贷货币危机,工业危机与农业危机同时并发,相互交织; 二,它持续时间特别长,达四年之久; 三,它破坏性特别大:不仅在危机期间资本主义世界的工业生产下降1/3以上,国际贸易额减少2/。图片指出了大危机笼罩下的世界正是说明了它波及范围很广,故选A项。生产过剩。它表现为产品大量积压,企业纷纷倒闭,生产大幅度下降,失业人数剧增,信用关系严重破坏,整个社会经济生活陷于混乱和瘫痪。1825年,经济危机第一次在英国爆发一后,每隔 8~10年重演一次。1929-1933年的经济危机是资本主义世界爆发的空前的大危机。

Smart home applications can share all kinds of helpful information with homeowners. There appears a new housing platform which can detect the stress on electricity — and the stress on the heart.

“There is a growing population of elderly people, and there are statistics to show that more and more of them are going to live alone in the home,” said Johann Siau, a senior lecturer at the University of Hertfordshire in the U.K., who was leading the InterHome project.

The system was originally designed to provide remote access (远程访问) to a house so owners could be more energy-efficient. In a small type of the system, set-in controller devices connect securely to the Internet. The owner can then monitor them with a cell phone or computer. User feedback helps the system adapt to routines, saving on electricity.

While thinking about responding to user behavior and an increasingly elderly population, the researchers decided to add wristband (手腕带) technology that senses important organs of the body such as body temperature and pulse, Siau said. “If someone were to fall, it would detect the fall and it would immediately start the monitor of the pulse to see if the person has gone into shock (休克),” he said.

The wristband communicates with the home system wirelessly. Data from the band can be securely transmitted to the home network and accessed by authorized users. “We’re working on trying to reduce it to a level where it could potentially be a wrist-sized product,” Siau said. 

But he warned that the technology presented new challenges. “When you start using that on a larger scale, you have issues of privacy or security,” he said. Siau said the InterHome home system isn’t intended to invade privacy. “We’re thinking about the elderly people who are living alone with no one looking after them,” he said. “Hopefully this will be able to decrease some concerns and possibly save a few lives.”
