The last two tornado seasons have been the deadliest in a decade, with 206 deaths. Everyone from the insurance industry toAl Gore worry that global warming may be causing more tornado【S1】activity. But there’s no baseline for comparison. That’s why we have【S2】no accurate record of tornadoes before the 1950s, back when it was possible for these brief, freakish funnels of air to blow over the unpopulated areas without a notice.【S3】 Tornado warnings have improved over the years; forecasterscan now issue warnings about 18 minutes after touchdown for 75【S4】percent of twisters. As longer-term forecasts, the science isn’t there【S5】yet, despite that you hear on the nightly news. " Television【S6】forecasters cater with the public’s curiosity about extreme weather,"【S7】says Michael H. Glantz, a professor at the University of Colorado at Boulder. Their goal, of course, is to be first with a forecast of trouble ahead. The number of deaths per tornado is greater in the South than in Tornado Alley(the Great Plains and part of the Midwest)—adisparity that can’t be explained for storm frequency or severity.【S8】Experts say things like terrain, population density, and the numberof mobile homes play a role. And the biggest factor might be timing:【S9】"In the Plains," explains Schaefer, "we have a many more clearly【S10】defined period of tornado activity, generally from March to late June.

Many of the most flexible examples of tool use in animals come from primates(the order that includes humans, apes, and monkeys). For example, many wild primates use objects tothreaten outsiders. Or there are many examples of tool use by【S1】the other mammals, as well as by birds and other types of animals.【S2】 Tools are used by many species in the capture or preparation offood. Chimpanzees use sticks and poles to bring up ants and termites【S3】(白蚁)from their hiding places. Among the most complex tool useobserving in the wild is the use of stones by Ivory Coast chimpanzees【S4】to crack nuts open. They select a large flat stone as anvil(a heavy【S5】block on which to place the nuts)and a smaller stone as a hammer.Stones suitable for use as anvils are not easy to find, but thus often a【S6】chimpanzee may carry a haul of nuts more than 40 meters to find a suitable anvil. The use of tools in chimpanzees is especiallyinteresting while these animals sometimes modify tools to make them【S7】better suited their intended purpose. To make a twig more effective【S8】for digging out termites, for example, a chimp may first strip it of its leaves. Surprisingly, there is also a species of bird that use sticks to【S9】probe holes in the search for insects. One of the species of Galapagos finch(雀类), the woodpecker finch, picks up or breaks off a twig, cactus spine, or leaf stem. This primitive tool is thenheld in their beak and used to probe for insects in holes in trees that【S10】the bird cannot probe directly with its beak. Birds have been seen to carry twigs from tree to tree searching for prey.【S1】

It is interesting to reflect for a moment upon the differences in the areas of moral feeling and standards in the peoples of Japan and the United States. The Americans divide these areas somewhatrigidly into the spirit and flesh, the two being in opposition in the【S1】life of a human being. Ideally, spirit should prevail but all too oftenit is the flesh which does prevail.【S2】 The Japanese make no this division, at least between one as【S3】good and the other as evil. They believe that a person has twosouls, each necessary. One is the "gentle" soul; other is the【S4】"rough" soul. Sometimes the person uses his gentle soul;sometimes he must use his rough soul. He does not favor his gentlesoul, neither he fight his rough soul. Japanese philosophers insist【S5】human nature in itself be good, and a human being does not need to【S6】fight any part of himself. He has only to learn how to use each soulproperly at the appropriate times. Virtue for the Japanese consists of【S7】fulfilling one’s obligations to others. Happy endings, either in life orin fiction, are neither necessary nor expected, while the fulfillment【S8】of duty provides the satisfying end, whatever the tragedy it inflicts.And duty includes a person’s obligations to these who have conferred【S9】benefits upon him and to himself as an individual of honor.

They select a large flat stone as anvil(a heavy【S5】block on which to place the nuts)and a smaller stone as a hammer.Stones suitable for use as anvils are not easy to find, but thus often a【S6】chimpanzee may carry a haul of nuts more than 40 meters to find a suitable anvil. The use of tools in chimpanzees is especiallyinteresting while these animals sometimes modify tools to make them【S7】better suited their intended purpose. To make a twig more effective【S8】for digging out termites, for example, a chimp may first strip it of its leaves. Surprisingly, there is also a species of bird that use sticks to【S9】probe holes in the search for insects. One of the species of Galapagos finch(雀类), the woodpecker finch, picks up or breaks off a twig, cactus spine, or leaf stem. This primitive tool is thenheld in their beak and used to probe for insects in holes in trees that【S10】the bird cannot probe directly with its beak.

The last two tornado seasons have been the deadliest in a decade, with 206 deaths. Everyone from the insurance industry toAl Gore worry that global warming may be causing more tornado【S1】activity.

As longer-term forecasts, the science isn’t there【S5】yet, despite that you hear on the nightly news. " Television【S6】forecasters cater with the public’s curiosity about extreme weather,"【S7】says Michael H. Glantz, a professor at the University of Colorado at Boulder. Their goal, of course, is to be first with a forecast of trouble ahead.

It is interesting to reflect for a moment upon the differences in the areas of moral feeling and standards in the peoples of Japan and the United States. The Americans divide these areas somewhatrigidly into the spirit and flesh, the two being in opposition in the【S1】life of a human being. Ideally, spirit should prevail but all too oftenit is the flesh which does prevail.【S2】 The Japanese make no this division, at least between one as【S3】good and the other as evil. They believe that a person has twosouls, each necessary. One is the "gentle" soul; other is the【S4】"rough" soul. Sometimes the person uses his gentle soul;sometimes he must use his rough soul. He does not favor his gentlesoul, neither he fight his rough soul. Japanese philosophers insist【S5】human nature in itself be good, and a human being does not need to【S6】fight any part of himself. He has only to learn how to use each soulproperly at the appropriate times. Virtue for the Japanese consists of【S7】fulfilling one’s obligations to others. Happy endings, either in life orin fiction, are neither necessary nor expected, while the fulfillment【S8】of duty provides the satisfying end, whatever the tragedy it inflicts.And duty includes a person’s obligations to these who have conferred【S9】benefits upon him and to himself as an individual of honor. Hedevelops through this double sense of duty, a self-discipline whichis at once permissive and rigid, depending upon the area which it is【S10】functioning.【S7】
