题目内容

【题目】读“某区域经纬网图”,回答下列问题。(5分)

(1)图中A点位于南、北半球中的__________半球。

(2)图中B点位于高、中、低纬度的 纬度。

(3)写出图中C点的经纬度

(4)图中D点位于东、西半球的________半球,该点位于C点的 方向。

【答案】

1)北

2)低

3

4)西 西南

【解析】

试题分析:

(1)我们以赤道为界将地球划分为南北半球,赤道以北为北半球,以南为南半球。据图可知:A点位于赤道以北,属于北半球。

(2)我们以30°、60°纬线为界将地球划分为高、中、低纬地区,0°~30°为低纬度地区;30°~60°为中纬度地区;60°~90°为高纬度地区。据图可知:B点位于低纬度

(3)在经纬网上,经线的度数叫做经度,若相邻两条经线的经度向东增大,就是东经,用符号E表示,若相邻两条经线的经度向西增大,就是西经,用符号W表示;纬线的度数叫纬度,若相邻两条纬线的纬度向北增大,就是北纬,用符号N表示,若相邻两条纬线的纬度向南增大,就是南纬,用符号S表示。据图可知: C点的坐标是(0°,0°)。

(4)我们以20°W和160°E组成的经线圈为界将地球划分为东西半球,20°W以东、160°E以西为东半球,20°W以西、160°E以东为西半球;地图上定向的方法很多,对于一般地图,通常是面对地图上北下南,左西右东;有指向标的地图,根据指向标定向,一般来说,指向标箭头指向北方;有经纬网的地图,根据经线指示南北方向,纬线指示东西方向来确定方向。据图可知:图中D点位于东、西半球的西半球,该点位于C点的西南方向

A city without cars would be very strange,right?But Venice(威尼斯)is such a city.

Venice is in the northeast of Italy.It wasn’t built on land,like Beijing or Shanghai,but on more than 110 islands.Seawater is everywhere around the city.

Even so,travel isn’t that difficult.The waterways have always been the best way to get around.There are 117 waterways and more than 400 bridges that can lead you where you want to go.

People in Venice move from place to place by boat.They like to enjoy the scenery and cool summer nights while taking boat trips.They can talk to other people as they go along.

Venice grew out of small islands in saltwater lakes when some Italians escaped from a war more than 1,500 years ago,and built homes there.

Water makes the city special,but it is also a big problem.

Once,people used too much underground water.This made the city get lower little by little.Now the city has gone down by 23 centimeters.

Another problem is the rising seawater.The temperature has risen over the years.This has made the ice of Arctic Ocean(北冰洋)melt(融化).

Every year,high waters hit the city in autumn and winter.When a lot of water comes,more than half of the city is underwater.

Scientists are trying different ways to stop the city from getting even lower.
