问题 综合

(11分)图为世界时(零时区)某日1时40分的光照图(阴影部分为黑夜),图中的A--E是这一天全球5个地点的太阳高度日变化曲线。读图完成下列问题。

(1)图中M点的地理坐标,经度:            ,纬度:            

(2)A—E五个地点中,自转线速度最小的是        。若流经五地的河流,两岸岩性相同,

则适合在河流右岸建设港口的地点是                    。(3分)

(3)此时,与北京处于同一日期的经度范围是                       

(4)在图中,画出这一天南极点的太阳高度日变化线。

(5)图示季节,下列地理现象叙述正确的是        

①松花江航运繁忙

②巴西高原草木茂盛

③澳大利亚正值小麦播种季节

④渤海湾正值赤潮严重期

答案

(1)155°E   70°N(2分)

(2)D    E(2分)

(3)25°W向东到180°(2分)

(4)在太阳高度值20°处向右画水平线(2分)

(5)②

本题考查光照图的综合分析。

(1)零时区的时刻为1:40,M点为12点,利用地方时计算方法可得其经度为155°E,C点日出6点,日落18点,应是赤道上的点,正午太阳高度为70°,由此可知太阳直射点在20°S上,M点刚好出现极夜,纬度应为70°N(90°-20°)。

(2)自转线速度最小的应是纬度最高的,五点D出现极昼,纬度最高。在北半球河流水主要侵蚀右岸,右岸适合建设港口,从昼夜长短上判断,E在北半球,C在赤道上,A、B、D在南半球。

(3)本题是计算日期的题,主要找180°经线和零点经线。

(4)南极点不自转,因此它的太阳高度日变化线应是一条20°的直线。

(5)北半球为冬季,南半球是夏季,巴西高原草木茂盛。

US military is attempting to develop a new style “insect robot” to replace the human soldier to go wherever he can’t. The greatest trouble this project has fallen across is how to enable the robot to fly freely like an insect, said an official of the Pentagon(五角大楼).

The Pentagon is seeking for the cooperation with scientists in hope of developing a new technique by which people can control the insect’s flight direction and pass on the information its eyes or other organs catch through the equipment set in its body, the official said.

It is thus designed that a tiny controlling chip will be equipped in an insect’s body when it is in chrysalis(蛹). As the insect grows, the cut made when fixing in the chip will be recovered. The chip will exist in forever. Scientists believe this won’t influence the insect, sound growth or the functions of internal organs.

The terminal target of the project is to set up a global system, in which the insect robots will be stationed in all parts of the world and stick to their posts till a new instruction is received. At that time the military can receive from all over the world clear image information within about 5 meters of the insects and that of a special target within 100 meters.

Years ago, Defense Advanced Research Projects Agency of US DOD(国防部) spent $3,000,000 carrying out a plan for training bees to detect landmines. But, no new progress has so far been made.

“According to the scientists, there is still enormous difficulty in technology in turning it into reality, such as the insects reproduction(繁殖), their adaptation to the surroundings and temperature and so on. However, this project is really challenging. If successful, it is equal to making countless small drone(无人机),”said the official of DOD.

小题1:According to the description of the passage, what is an insect robot like?

A.An insect made of a certain metal.

B.A robot looking like an insect.

C.An insect with a chip in its body.

D.A tiny flying robot.小题2:As for the design that an insect robot can receive and send information, how do you infer(推测) it works?

A.There must be a controlling chip well connected with the insect’s brain.

B.The insect’s eyes and other organs must be replaced by some special equipment.

C.All the insect’s concerned organs must be controlled by a chip.

D.The insect must be so well trained as to make full use of its organs.小题3:When the project is completed, US military will    .

A.have a clear picture of almost every part of the world

B.have insect robots from all over the world

C.see clearly the things within 10 to 100 meters

D.get many insects which obey their orders小题4:Of the following technical problems, which is the one the scientists can’t solve so far?

A.They can’t keep sound growth of the insects.

B.They can’t ensure the insects to produce their young.

C.They can’t fix a chip in an insect.

D.They can’t make sure the internal organs function well.小题5:What does the underlined word “terminal” in the fourth paragraph mean?

A.Leading.

B.Vital.
