人口算术密度是一个国家的总人口与总面积之比,人口生理密度是一个国家的总人口与可耕地面积之比。根据所学知识分析下表完成下题。

国家人口算术密度(人/km2)人口生理密度(人/km2)
加拿大335
美国30156
埃及703 503
中国129934
英国241963
印度313559
日本3363 054
荷兰4321 601
孟加拉国9101 359
小题1:“地广人稀”但耕地资源缺少的国家是

A.加拿大

B.美国

C.埃及

D.印度小题2:耕地面积占国土面积1/2以上的国家是

A.美国

B.荷兰

C.孟加拉国

D.加拿大小题3:对比表中中国、印度两国的统计数字

A.印度的人口压力较中国大

B.中国的人口压力较印度大

C.中国的人口压力与印度相当

D.中、印两国的人口压力都较小

答案

小题1:C

小题2:C

小题3:B

小题1:埃及全境90%以上是沙漠,故该国人口算术密度小,但人口生理密度大,即其耕地资源相对缺少。

小题2:人口算术密度=总人口/总面积

人口生理密度=总人口/可耕地面积

可耕地面积/国土总面积=人口算术密度/人口生理密度

美国:30/156 小于1/2

荷兰:432/1 601 小于1/2

加拿大:3/35 小于1/2

孟加拉国:910/1 359 大于1/2

小题3:对比表中中国、印度两国人口算术密度和人口生理密度数字可看出,中国人口生理密度是印度人口生理密度的近两倍,说明我国人均耕地比印度少得多,中国人口压力较印度大。

Upon waking up, Jim found himself lying on a stretch of sandy shore with his face half-buried in the sand.  He found, that his clothes had been almost torn apart.  His arms ached and his body was heavy like stone.  Before he could stand up, he was brought to his knees due to exhaustion.  As he lay on the sand, he began to study the environment for signs of human activities.  But there was nothing except for a few trees and some stones within eyesight.

He remembered how, a few hours before, he had still been struggling for survival in the vast South China Sea.  The boat that had carried his friends and him out to sea for a fun fishing trip had run into a terrible storm.  James, who was the captain of the boat, and had been at the wheel, lost control of the boat.  The boat moved from side to side in the storm.  Suddenly, it hit a sharp object, most probably a rock from the sea and was wrecked.

Jim could not remember how he had managed to drift onto land.  His friends were not in sight.  He was saddened by the fact that they might have all drowned.  Then he suddenly saw a thin column of smoke on the far side of a hill.  “Could it be a house?”  Jim asked himself.  Even if it wasn’t, it gave him some fresh hope of surviving the ordeal that he was going through.  He struggled on towards the place from where the smoke was rising.

Finally, he found himself at the top of the hill.  He saw a little green valley dotted with a few huts and trees in the sun.  His eyes were not playing tricks on him.  There was a village located at the bottom of the valley.  The sight gave him renewed hope.  He began to run toward the village with his last ounce of energy.
