(1)当图中A点气温为18.2℃时,B点应为______℃.(仅从地形因素考虑)

(2)a、b为河流上源的两条支流,其中流速较快的是______.

(3)图中地区欲建一水库,那么水库大坝应建在什么地方最合适?(请在图中用--一标出)

(4)甲村计划在C点建一造纸厂,你认为是否合适?______,请说明理由:______.

(5)甲村位于乙村的______方向.如果根据行政管理的需要,将甲、乙两村合并到其中的一个村落,你认为应合并到哪一村较为合适?______,你的理由是______.

答案

(1)当图中A点气温为18.2℃时,B点应为21.2℃,其相对高度是500米;

(2)a、b为河流上源的两条支流,其中流速较快的是b,该处等高线密集,坡度陡;

(3)图中地区欲建一水库,水库大坝应建在C点附近,该地区施工量小,水量丰富;

(4)甲村计划在C点建一造纸厂,不合适,其理由是造纸厂排放出的污水会对河流造成污染,从而影响甲、乙两村对河水的利用;

(5)据图中的指向标可得:甲村位于乙村的西南方向.如果根据行政管理的需要,将甲、乙两村合并到其中的一个村落,应合并到乙村较为合适,其理由是乙村水源充足、交通便利、地形开阔、发展空间大.

故答案为:

(1)21.2;

(2)b;

(3)

(4)不合适;造纸厂排放出的污水会对河流造成污染,从而影响甲、乙两村对河水的利用;

(5)西南;乙村;乙村水源充足、交通便利、地形开阔、发展空间大.

完形填空
Africans see many advantages by uniting the continent into a single nation, or by uniting several small nations of a particular region into a nation. In unity there is strength. Africans often point to the United States, formed by the original 13 states, as an example of this principle. Africa now is divided into many weak nations. United, they would be much stronger. Africans could then more easily deal with foreign efforts to control them. Also it would be easier to plan and carry out big projects like the building of highways and dams.
The considerations for African unity go beyond the practical advantages it brings. As we have seen, one factor is that the feeling of belonging to a particular nation is not strong among Africans. If, for example, you were to ask a man from Paris " What are you?", he would certainly answer " A Frenchman". Ask the same question of a man from Ibadan in Nigeria and he might give one of three answers, or all three, depending on his education and outlook. He might say, " A Yoruba" (his people), or " A Nigerian," or just simply " An African."
Another factor that enters into the desire for unity is that African leaders throughout the continent feel that they all have many things in common. They all lived through the experience of colonial rule. Many of them went to school and university with men who now lead other African countries. They all feel very angry about the way in which they were treated in the past. Compared with these strong bonds (结合),which overshadow the borders of nations, the idea of building separate nations does not have so much meaning. Some leaders say they are ready, in fact, to give up their separate nations.
Many nations have written into their constitutions(宪法), and they may give up their powers to a Pan-African government that will come into being.
