问题 综合

读下面两幅经纬网示意图,回答问题(12分)

(1)写出各点的经纬度:A             B          C             D          

(2)写出下列各点所在的半球位置:A                           C                      

(3)写出下列各点所处的五带位置: A                D            

(4)写出下列各点的纬度范围(高、中、低):B                C            

答案

⑴A:10°W,10°N             B:10°E,10°S   

C:170°E,50°S             D:170°W,70°S

(2)A:东半球、北半球   C:西半球、南半球

(3)A:热带   D:南寒带

(4)B:低纬度  C:中纬度

题目分析:(1)根据东大为东经,西大为西经,北大为北纬,南大为南纬,各点的经纬度:A为10°W,10°N,             B为10°E,10°S;C为170°E,50°S,D为170°W,70°S。

(2)根据南北半球的分界线为赤道,东西半球的分界线为20°W,160°E;所以各点所在的半球位置:A为东半球、北半球,C为西半球、南半球;(3)根据23.50N:北回归线,热带与北温带的分界线;23.50S:南回归线,热带与南温带的分界线; 66.50N:北极圈,北寒带与北温带分界线; 66.50S:南极圈,南寒带与南温带分界线;各点所处的五带位置:A为热带;D这南寒带;(4)根据300纬线是中低纬的分界线,600纬线是中高纬的分界线。,各点的纬度范围,B为低纬度; C为中纬度。

点评:本题还可以考查经度零度确定:国际上规定,把通过英国格林尼治天文台旧址的那条经线定为00经线;00经线也叫本初子午线。度数划分:由00经线向东、向西各分为180度。表示方法:以00经线始东边东经度(用字母E表示)、西边西经度(用字母W表示)。度数变化:东经度向东(右)逐渐增大;西经度向西(左)逐渐增大。东大东经,西大西经。1800:东西经线的分界线,东边西经度、西边东经度。纬度零度确定:国际上规定,最长的纬线为00纬线,即赤道。度数划分:由00纬线向北、向南各分为90度。

That Will Teach You, Bear!

One beautiful day, Bear was out hunting. As he walked past a fallen tree, he heard a small voice shout, “Watch your feet!”

Bear looked down and saw Cricket (蟋蟀). “You almost destroyed my house,” Cricket said.

“I’ll walk wherever I want to,” Bear shouted as he showed off his size and strength.

Cricket shouted back, “But it’s my house, and I should protect it!”

This made Bear so furious that he said he would destroy the house, Cricket, and all of Cricket’s family. This made Cricket angry. “I have a friend who is only half my size, but he is strong enough to beat you in a fight.”

Bear laughed and said, “Go and get your friend, Cricket. I’ll return tomorrow, and we’ll see who can win in a fight.”

The next morning, Bear returned to Cricket’s house. “Come out, brave Cricket,” called Bear. Suddenly he felt a terrible ache on his back. He yelled, but Cricket’s friend Mosquito (蚊子) continued stinging (叮) until Bear yelled, “I give up!”

Just then Cricket appeared at the door of his house. Cricket told Bear to leave and never return. Bear quickly ran away.
