题目内容

【题目】地图比例尺指的是地图上的线段长度与实地相应距离长度之比。它表示地图图形的缩小程度,故又称缩尺。据此回答下列问题。

【1】图幅相同时,比例尺越大则地图

A表示的范围越大

B.表示的概括性越强

C.表示的地理要素越详细

D.与实际地理图形的差别越大

【2】在图幅相同的两幅等高线地形图上假设两图中相邻等高线的图上间距都相等

A若等高距相同,则坡度一定相同

B.若等高距相同,则比例尺越大坡度越大

C.若比例尺相同,则等高距越大坡度越小

D.若比例尺相同,则坡度一定相同

【3】在地形剖面图上,若要增强地势的起伏感,可以采用的办法是

A扩大水平比例尺

B.扩大水平比例尺和垂直比例尺

C.扩大垂直比例尺

D.缩小水平比例尺和垂直比例尺

【4】某区域规划图的比例尺为1250000,实际面积为86平方千米,若将该规划图的图幅扩大3倍重新进行绘制,则新图的比例尺大约为

A1125000 B.1500000

C.1750000 D.11000000

【答案】

【1】C

【2】B

【3】C

【4】A

【解析】

试题分析:

【1】图幅相同时,比例尺越大,表示的范围越小,A错。表示的越详细,C对、B错。与实际地理图形越相近,D错。故选C。

【2】在图幅相同的两幅等高线地形图上假设两图中相邻等高线的图上间距都相等若等高距相同,则坡度在比例尺相同的情况下一定相同,A错。若等高距相同,则比例尺越大坡度越大,B对。若比例尺相同,则等高距越大坡度越大,C错。若比例尺相同,等高距也相同,则坡度一定相同,D错。故选B。

【3】在地形剖面图上,若要增强地势的起伏感,可以扩大垂直比例尺,C对。扩大水平比例尺,会使地表变得更加平缓,A错。扩大和缩小水平比例尺和垂直比例尺,起伏状况不会发生变化,BD错。故选C。

【4】若将该规划图的图幅扩大3倍重新进行绘制,就是图幅面积为原来4倍,比例尺为原来的1/2,故选A。

A Race Against Death

It was a cold January in 1925 in North Alaska. The town was cut off from the rest of the world due to heavy snow.

On the 20th of that month, Dr.Welch a Sick boy, Billy, and knew he had diphtheria, a deadly infectious(传染的)disease mainly affecting children. The children of Nome would be if it struck the town. Dr.Welch needed medicine as soon as possible to stop other kids from getting sick. , the closest supply was over 1,000 miles away, in Anchorage.

How could the medicine get to Nome? The town`s was already full of ice, so it couldn’t come by ship. Cars and horses couldn’t travel on the roads. Jet airplanes and big trucks didn’t exist yet.

January 26, Billy and three other children had died. Twemty more were . Nome`s town officials came up with a(n) . They would have the medicine sent by from Anchorage to Nenana. From there, dogeled(狗拉雪橇)drivers—known as “mushers”—would it to Nome in a relay(接力).

The race began on January 27. The first musher, Shannon, picked up the medicine from the train at Nenana and rode all night. he handed the medicine to the next musher, Shannon`s face was black from the extreme cold.

On January 31,a musher named Seppala had to a frozen body of water called Norton Sound .It was the most part of the journey. Norton Sound was covered with ice,which could sometimes break up without warning.If that happened,Seppala might span>fall into the icy water below.He would ,and so would the sick children of Nome.But Seppala made it across.

A huge snowstorm hit on February 1.Amusher named Kaasen had to brave this storm.At one point,huge piles of sonw blocked his .He had to leave the trail (雪橇痕迹)to get around them.Conditions were so bad that it was impossible for him to the trail again. The only hope was Balto,Kaasen’s lead dog, Balto put his nose to the ground, to find the smell of other dogs that had traveled on the trail.If Balto failed,it would mean disaster for Nome.The minutes passed by.Suddenly, Balto began to .He had found the trail.

At 5:30 am on February 2, Kaasen and his dog in Nome. Within minutes,Dr.Welch had the medicine.He quickly gave it to the sick children.All of them recovered.
