【题目】读经纬网图,完成各题

(1)如图为经纬网图,下列叙述正确的是
A.甲、乙两图中,比例尺较大的是图甲
B.A,B均在南半球,西半球
C.B地的经纬度为(23.5°S,126°E)
D.当太阳直射B地时,广州市学生正午的身影一年中最短
(2)图中 A点的位置是( , 60°S),B点的正确位置是(

【答案】
(1)D
(2)30°W;12 6°E;23.5°N
【解析】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.读图分析可知:(1)甲乙两图中,甲图所跨的经纬度广,其范围大,比例尺小;A点位于南半球,B点位于北半球;B点的经纬度是23.5°N,126°E;当太阳直射B地即北回归线时,广州市太阳高度最大,其正午影子最短.(2)依据经纬度的判读,图中 A点的位置是30°W,60°S;B点的经纬度位置是126°E,23.5°N.所以答案是:(1)D;(2)30°W;12 6°E;23.5°N.

【题目】Gareth Ellis, 13, is the youngest son of Alan, an engineer, and Kath, a teacher. His older brothers work in banking and computers, but Gareth's dream was always to become a clown(小丑).Three years ago, Alan, Kath and Gareth joined the circus(马戏团). People laugh when we tell them,' saysKath. 'But it's true. Gareth has wanted to be a clown since we took him to the circus when he was three.'

When Alan lost his job, he and Kath decided to see if they could find full-time circus jobs. They both got jobs with a famous circus and Gareth began training to become a clown. He calls himself Bippo. They travel with the circus during the summer and return home for the winter. Gareth's brothers are old enough to look after the house while they are away.

'I can't say it was easy,' says Kath. 'There was a lot to think about and organize. We only had a car and a very small caravan(大篷车)to sleep in, and we were leaving behind our lovely house. The only thing Gareth missed was his long, hot baths.'

'People ask about my education,' says Gareth, 'but from the beginning, wherever we go, someone has always come to teach me. I follow the same books as everyone back at school and I've got a computer. I've never fallen behind my classmates.'

And the future? 'It was a difficult decision,' says Kath, 'but there was no other way to teach Gareth about being a clown. I'm happy to say it's working, and we're enjoying it.' And Gareth? 'I'm going to be the main clown in a circus one day', he says, 'perhaps Bippo's circus.'
