标题: 我想选D...大家来看看！！！ [打印本页] 作者: 小黛安 时间: 2011-8-23 02:21 标题: 我想选D...大家来看看！！！ Meteorologists say that if only they could design an accurate mathematical model of the atmosphere with all its complexities, they could forecast the weather with real precision. But this is an idle boast, immune to any evaluation, for any inadequate weather forecast would obviously be blamed on imperfections in the model. Which of the following, if true, would cast the most serious doubt on the meteorologists’ boast, aside from the doubt expressed in the passage above? (A) The amount of energy that the Earth receives from the Sun is monitored closely and is known not to be constant. (B) Volcanic eruptions, the combustion of fossil fuels, and several other processes that also cannot be quantified with any accuracy are known to have a significant and continuing impact on the constitution of the atmosphere. (C) As current models of the atmosphere are improved, even small increments in complexity will mean large increases in the number of computers required for the representation of the models. (D) Frequent and accurate data about the atmosphere collected at a large number of points both on and above the ground are a prerequisite for the construction of a good model of the atmosphere. (E) With existing models of the atmosphere, large scale weather patterns can be predicted with greater accuracy than can relatively local weather patterns.作者: egretlee 时间: 2011-8-23 08:15
为啥我脚着像B呢。。。答案是什么？作者: yuxiao0255 时间: 2011-8-23 08:45

的确是选B. 但是为什么不是D呢？作者: hanshipeng 时间: 2011-8-23 23:28
这题主要是找到一个答案说明预测不准并不能完全归咎于模型的imperfect。
