问题 问答题

读图,回答问题:

(1)写出A、B两地的地理坐标:A______,B______.

(2)从东西半球看:B在______半球,C在______半球.

(3)从南北半球看:A在______半球,D在______半球.

(4)从五带来看:C在______带,D在______带.

(5)从方向上来看:D点位于A点的______方向.

(6)从大洲、大洋的位置来看,C点位于______洋.

答案

(1)根据在经纬网上,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,读图可知,A地的地理坐标是(20°S,130°E),B地的地理坐标是(10°S,100°W);

(2)东西半球分界线是20°W和160°E组成的经线圈,20°W以东、160°E以西为东半球,20°W以西、160°E以东为西半球,根据B点的经度(100°W)、C点的经度(15°W)可知,B在西半球,C在东半球;

(3)南北半球与南北纬的分界线是赤道,以北为北半球(北纬),以南为南半球(南纬),读图可知,A在南半球,D在北半球;

(4)热带的纬度范围是23.5°N-23.5°S,北温带的纬度范围是23.5°N-66.5°N,北寒带的纬度范围是66.5°N-90°N,南温带的纬度范围是23.5°S-66.5°S,南寒带的纬度范围是66.5°S-90°S,读图可知,C的纬度是20°N,D点的纬度是30°N,因此可知,C在热带,D在北温带;

(5)读图可知,A地的经纬度是(20°S,130°E),D地的经纬度是(30°N,110°E),根据两地的经纬度可判断,D点位于A点的西北方向;

(6)读图可知,C点的经纬度是(20°N,15°W)位于西半球.

故答案为:(1)20°S,130°E;10°S,100°W;(2)西;东;(3)南;北;(4)热;北温;(5)西北;(6)大西.

     Facebook means never having to say goodbye.The social media website has earned a reputation for

reconnecting old friends.Last week,a guy whom I hadn't seen since my bachelor party five years ago

sent me a friend request.I accepted and waited for "Easy E" to send me a greeting of some kind.He had

sought me out,after all.

     I learned from his profile that he was in a relationship and had a son.However,I'm pretty sure we won't ever write walltowall,let alone email each other.But he'll remain a friend of online until one of us makes a

point of removing the other from his official list.

     My pool of friends consists of family members,college buddies,coworkers from past and  present,and

friends of friends.There are 35 in all.If I spent some time uploading old email addresses,I'm confident that

I could increase my friend count actually.

     A person could make a mission out of reconnecting with childhood friends,former  classmates,distant

cousins, and those one would like to get to know better.And some people can even handle hundreds of

onscreen relationships,keeping up with the daily happenings of  their small army of companions.After all,

there are worse fates than having too many friends.

      Thanks to email,the inability to schedule facetoface meetings no longer means a  friendship must come

to a close.But even with email,people will lose touch if one or both  parties stop writing back.That's

normal.People move from school to school,job to job,city  to city.You never have to feel guilty for

breaking away.

      Every day,the masterminds of Web 2.0 find new ways of making human communication  easier.

However,convenience_can_be_a_crutch(拐杖). Some things shouldn't be simplified.When it comes to
