有关太阳辐射的叙述,错误的是:            ( )

A.辐射的能量只有极少的一部分到达地球

B.辐射能与地球上的水循环、大气环流关系不大

C.年太阳辐射总量最低的地方位于四川盆地

D.石油、天然气的能量来自太阳辐射

答案

答案:B

题目分析:太阳辐射是太阳以电磁波的形式向宇宙空间辐射能量,这种能量是十分巨大的,其中能到达地球的太阳辐射能源只相当于太阳辐射能量的22亿分之一,这些能量不仅维持了地表的温度,还是地球上水、大气运动和生命活动的主要动力,它为地表提供的能源不仅是我们在直接利用的太阳能,还在而煤炭、石油、天然气,这也是早期的太阳能。在我国太阳能最丰富的是青藏高原,最少的是四川盆地。故选B

点评:本题主要考查考生对“太阳为地表提供的能量”相关内容是掌握情况,试题属于理解性较强的试题,属于中档题目。

单项选择题

I want to divide human understanding into two kinds—classical understanding and romantic understanding. In terms of ultimate truth, a distinction of this sort has little meaning, but it is quite legitimate when one is operating within the classic mode used to discover or create a world of underlying form. The terms classical and romantic, as Phaedrus used them, mean the following:
A classical understanding sees the world primarily as underlying form itself. A romantic understanding sees it primarily in terms of immediate appearance. If you were to show an engine or a mechanical drawing or electronic scheme to a romantic, it is unlikely he would see much of interest in it. It has no appeal because the reality he sees is its surface. Dull, complex lists of names, lines and numbers. Nothing interesting. But if you were to show the same blueprint or give the same description to a classical person, he might look at it and then become fascinated by it because he sees that within the lines and shapes and symbols is a tremendous richness of underlying form.
The romantic mode is primarily inspirational, imaginative, creative, intuitive. Feelings rather than facts predominate. "Art" when it is opposed to "Science" is often romantic. It does not proceed by reason or by laws. It proceeds by feeling, intuition and esthetic conscience. In the northern European cultures the romantic mode is usually associated with femininity, but this is certainly not a necessary association.
The classic mode, by contrast, proceeds by reason and by laws—which are themselves underlying forms of thought and behavior. In the European cultures it is primarily a masculine mode and the fields of science, law and medicine are unattractive to women largely for this reason. Although motorcycle riding is romantic, motorcycle repair and maintenance are purely classic. The dirt gives it such a negative romantic appeal that women never go near it.

From the context of Paragraph 1, we can learn that the author is, or was at least at the moment when he or she was writing this passage, in ______ .

A.the classic mode

B.the romantic mode

C.both modes

D.neither modes
