(1)A点的经度是________,纬度是________

(2)图中四地中,位于西半球的是________地,位于东半球的是________地,

(3)地在地的________方向, 地在地的________方向, 地在地的________方向。

【答案】

(1)90°E;60°

(2) ②③④

(3)正北 西北 东北

【解析】

试题分析:

(1)由经线和纬线相互交织所构成的网络叫做经纬网,利用经纬网可以确定地球表面任何一个地点的位置。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。从图中看出,A点的经纬度是(90°E,60°N )。

(2)东西半球的划分是以20°W和160°E组成的经线圈为界,东半球的经度范围为20°W0°→160°E,西半球的经度范围为160°E180°←20°W。从经纬网图看出,点位于180°经线上,且在北极圈以北,应位于西半球,有极昼极夜现象,的经度是0°的经度是120°E,都在东半球,地位于北回归线上,有太阳光直射现象。也在东半球。

(3)由纬度位置来看,按照地球上五带的划分,地属于北寒带,地属于北温带。从图中看出,两地在同一条经线上,因此地在地的正北方向;地在地的西北方向;地在地的东北方向。

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.
