“竹枪一支，打得妻离子散，未闻炮声震地；铜灯半盏，烧尽田地房廊，不见烟火冲天。” 对这句话理解正确的是 （ ）
A．揭示了鸦片输入的危害
B．说明中国人民不勇敢，惧怕竹枪火炮
C．竹枪比火炮有较大危害
D．因为吸烟中国人民内部互相仇杀
答案：A
题目分析：“竹枪一支，打得妻离子散，未闻炮声震地；铜灯半盏，烧尽田地房廊，不见烟火冲天。” 这句话揭示了鸦片输入的危害，故选A。
点评：关于鸦片输入的危害，学生还要知道，它导致了中国白银大量外流，使清政府出现了严重的财政危机；另外它还导致了中国军队战斗力的严重下降。
Passage Three
| In the world of climate change, it is in the Earth’s Cold regions where trends can most easily be seen. The cryosphere, where water is found in solid form, is among the most sensitive regions to temperature change. The sensitivity of ice and snow to temperature changes is an early indicator of even relatively small differences, says University of Colorado at Boulder senior researcher Richard Armp. He has found that today’s receding and thinning sea ice, mountain glacier mass losses, decreasing snow extent, melting permafrost (永久冻土), and rising sea level are all consistent with warming. Global mean temperatures have risen one degree Fahrenheit over the past 100 years, with more than half of the increase occurring in the last 25 years, observes Armp who is affiliated with the National Snow and Ice Data Center headquartered at CU-Boulder. "As slight as that may seem, it’s enough to make a difference," said Armp. "Now, long-term monitoring of a series of cold region, or cryospheric, parameters (参数) shows that for several decades the amounts of snow and ice around the world have been decreasing. " The extent of Arctic sea ice is shrinking by about 3 percent per decade, but the trends are not uniform. While recent studies have indicated that the ice thickness also had decreased over several decades, new information shows that the ice may have thinned rapidly, Armp said. Examination of springtime ice thickness in the Arctic Ocean indicates that the mean ice thickness decreased 1.5 meters (4. 8 feet) between the mid-1980s and early 1990s. To mark its 25th anniversary, the National Snow and Ice Data Center has organized a special session at the 2001 Fall Meeting of American Geophysical Union, taking place this week in San Francisco, that illuminates overall changes in the cryosphere. The session begins Tuesday and extends through Thursday afternoon, with 75 contributions from all areas of cryospheric study. Papers and posters include examinations of lake and river ice, glacier dynamics, and mass ice balance studies in polar and continental glaciers, regional and polar snow cover trends, and variations in Canadian ice cap elevations. |
