2006 年重庆高考卷的e文 73题

The flag,the most common symbol(象征) of a nation in the modern world,is also one of the most ancient.With a clear symbolic meaning,the flag in the traditional form is still used today to mark buildings,ships and other vehicles related to a country.
The national flag as we know it today is in no way a primitive(原始的)artifact.It is ,rather,the product of thousands of years' development.Historians believe that it had two major ancestors,of which the earlier served to show wind direction.
Early human beings used very fragile houses and boats.Often strong winds would tear roofs from houses or cause high waves that endangered travelers.People's food supplies were similarly vulnerable.Even after they had learned how to plant grains,they still needed help from nature to ensure good harvests.Therefore they feared and depended on the power of the wind,which could bring warmth from one direction and cold from another.
Using a simple piece of cloth tied to the top of a post to tell the direction of the wind was more dependable than earlier methods,such as watching the rising of smoke from a fire.The connection of the flag with heavenly power was therefore reasonable.Early human societies began to fix long pieces of cloth to the tops of totems(图腾) before carrying them into battle. They believed that the power of the wind would be added to the good wishes of the gods and ancestors represented by the totems themselves.
These flags developed very slowly into modern flags. The first known flag of a nation or a ruler was unmarked:The king of China around 1000 B.C. was known to have a white flag carried ahead of him.This practice might have been learned from Egyptians even further in the past,but it was from China that it spread over trade routes through India, then across Arab lands, and finally to Europe,where it met up with the other ancestor of the national flag. 73.The earliest flags were connected with heavenly power because.
A.they could tell wind direction
B.they could bring good luck to fighters
C.they were handed down by the ancestors
D.they were believed to stand for natural forces
这道题的therefore 不是表示因果关系的么， 它前面是原因 它 后面就说他是结果了啊，所以答案选a 吧！ 请老师指点迷津，学校的老师没有说明白， 多谢您了！

解题过程：
一定要注意题干中的要点,The earliest flags were connected with heavenly power because,所以这道题目是问最早的旗帜与大自然的力量有关系的原因是什么?答案在下面相关的段落里找,特别是红色字体的句子 :Therefore they feared and depended on the power of the wind,which could bring warmth from one direction and cold from another.( 因此,他们害怕并依靠风能,风能可以从一个方向带来温暖也可以从另一个方向带来寒冷)
Using a simple piece of cloth tied to the top of a post to tell the direction of the wind was more dependable than earlier methods,such as watching the rising of smoke from a fire.( 用一块布绑在一根竹竿上来辩明风的方向要比早期的方法更可靠)The connection of the flag with heavenly power was therefore reasonable.( 所以把旗帜同大自然的力量联系起来就很合理了) Early human societies began to fix long pieces of cloth to the tops of totems(图腾) before carrying them into battle. ( 早期人类在上战场之前就开始把很长的一块布绑在图腾的最上面)They believed that the power of the wind would be added to the good wishes of the gods and ancestors represented by the totems themselves. ( 他们相信风的力量能带来上苍和图腾本身所代表的祖先对他们的祝福)
所以,早期的旗帜被认为是代表着大自然的力量.答案选D
最终答案：略
