Although the dream of the home robot
has not died, robots have had their greatest impact in factories. Unimate, the
first industrial robot, went to work for General Motors in 1961. Even at a time
when computing power was costly, robots made excellent workers and proved that
machines controlled by computers could perform some tasks better than humans. In
addition, robots can work around the clock and never go on strike. There are now about 800 000 industrial robots around the world, and orders for new robots in the first half of 2007 were up a record 26% from the same period in 2006, according to the United Nations Economic Commission for Europe (UNECE). Demand is increasing as prices fall: a robot sold in 2007 cost less than a fifth of an equivalent robot sold in 1990, for example. Today, in car factories in Japan, Germany and Italy, there is more th A. become more and more popular among families B. be made just like the ones in Hollywood movies C. be used more widely in agricultural, contexts D. be able to do housework with high intelligence [单项选择]Why do men die earlier than women The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of aging on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age. "We have found that the power of the male heart falls by 20—25 percent between 18 and 70 years of age," said the head of the study, David Goldspink of Liverpool John Moores University in the UK. "Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men," said Goldspink. "This is part of the aging process." What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s. "This gender difference might just e A. enable your heart to beat much faster B. find out the reason for aging C. exercise regularly to keep your heart healthy D. prevent your cells from being lost [单项选择]All Sue Rodriguez wanted was to die with dignity and within the law, but it turned out that she could not do both. Last week the British Columbian woman, totally disabled by amyotrophic lateral sclerosis (肌萎缩性侧索硬化), challenged Canada’s law against doctor - assisted suicides and took her life, presumably with the help of drugs administered by a still unidentified physician. The case caused a political and legal furor across Canada not only because the law was challenged, but also because a Member of Parliament was at Rodriguez’s side when she died.
Svend Robinson, an enthusiastic right-to-die supporter and Canada’s only openly gay federal legislator, retained a criminal lawyer to defend him against possible charges that he encouraged the commission of a crime. The M.P. said he was present during the suicide at Rodriguez’ s invitation: "I considered it a privilege and an honor that she trusted me." Rodriguez,43, spent two years challenging the 1892 law that makes doctor-assisted A. resulted in the immediate abolition of the 1892 law B. created an uproar in Canada C. made him invulnerable to legal action D. attracted little attention in Canada [单项选择]
People who are overweight at 40 are likely to die at least three years sooner than those who are slim, meaning that being fat during middle age is just as damaging to life expectancy as smoking, researchers say in a new study. The study was conducted by Dutch researchers and was published in The Annals of Internal Medicine. [多项选择]1. 大学校园里的讲座丰富多采
