  • [单选题]初一六班夏老师上课期间发现班里小强的座位中放了一把短刀,但考虑到同学正在认真学习,就继续上课。第二天,听说小强将同伴小雨砍伤。在此事件里( )。
  • 对于小雨所受伤害,学校也应承担相应责任

  • 解析:《学生伤害事故处理办法》第九条规定:学校教师或者其他工作人员在负有组织、管理未成年学生的职责期间,发现学生行为具有危险性,但未进行必要的管理、告诫或者制止的,学校应当依法承担相应的责任。教师在课上发现小强不良行为,没有及时制止,属于管理未成年人职责期间,出现事故应该由学校负责。故选择A。

  • [单选题]教师让学生"即兴回答问题",这是调动学生的( )。
  • 直觉思维

  • 解析:直觉思维是未经逐步分析就迅速对问题答案作出合理的猜测、设想或突然领悟的思维。"即兴回答问题",就是直觉思维的体现。

  • [单选题] Since ancient times, the destructive effects of earthquakes on humanlives and property have encouraged the search for reliable methods of earthquake prediction. This challenge remains and modern scientists continue to search for reliable methods to determine the time, place and intensity of individual quakes. One prediction technique involves an analysis of the recurrence rates of earthquakes as indicators of future activity. Earthquakes are concentrated in certain areas of the world which are subject to constant movements of earth's plates and it is in these areas that scientists focus their investigations. This search for pre-earthquake phenomena has received particular attention. In contrast to the ancient Greeks and Romans, who relied on the crying of dogs as a warning sign, modem scientists have focused on physical evidence for a coming earthquake. Evidence of plate strain can be found by measuring relative movements, while chemical changes also offer signals for scientists. Analysis of the changes in magnetic properties and conductivity of rocks provides further data for prediction. The electrical and magnetic properties of crustal rocks are particularly sensitive to strain. The conductivity of crustal rock is determined by the degree to which the rock is soaked with fluid and the electrolytic properties of those fluids. Before large earthquakes, small fractures develop in rocks, which change the quantity of fluid present. These changes can be measured and provide useful data. However, similar changes in the fluid, bearing capacity of rock can occur as a result of other factors such as changes in the water table, and therefore this technique is not entirely reliable. The ancient believe that the behavior of birds, cats and dogs provides evidence of inevitable earthquakes has recently been attended as a result of tests carried out in California. It has been shown that changes taking place in the metabolic rates of these animals correlate with subsequent seismic activity. It is assumed that the animals are sensitive to the seismic waves which precede major quakes. In zones where earthquakes are known to occur, improved construction techniques can significantly reduce the effects of seismic waves. If more accurate information regarding the time and intensity were available, govemments could take even more effective measures to reduce the impact on human life, if, however, an entirely accurate prediction technique became available, there would be significant social and political implications.
  • Recurrence rates of earthquakes can help predict future quakes because ________.

  • continuous plate movements often result in earthquakes in certain areas

  • 解析:1.细节题。由题干可定位至第一段最后一句,根据“Earthquakes are concentrated in certain areas of the world which are subject to constant movements of earth's plates”可知,地震总是集中在受到地球板块持续运动影响的特定区域。故选项D正确。 2.细节题。短文第三段第一句指出“Analysis of the changes in magnetic properties and conductivity of rocks provides further data for prediction.”即对岩石的磁性和导电性变化的分析为地震预测提供了很多数据。故选项B正确。 3.细节题。根据短文第三段第二句“The electrical and magnetic properties of crustal rocks are particularly sensitive to strain.”即外壳岩的电磁性对压力很敏感,由此可判断出答案为B。 4.细节题。短文第三段最后一句指出“However,similar changes in the fluid,bearing capacity of rock can occur as a result of other factors such as changes in the water table, and therefore this technique is not entirely reliable.”即其他因素也会导致岩石含水量的变化,比如地下水位的变化。因此这种方法也不是完全可靠的。故选项A正确。 5.推断题。根据短文最后一段中“…improved construction techniques can significantly reduce the effects of seismic waves”可知选项C正确。
