问题 综合

读“二分二至示意图” (从地球北极上空俯视)和“太阳光照示意图”,回答问题。(每空1分,共5分)

(1)甲、乙分别处于A、B、C、D四点中的哪一点附近?甲图         点,乙图       点。

(2)在甲图中该日正午太阳高度达到最大值的范围是                    

(3)乙图太阳直射点的坐标为            。180°经线的地方时为            

答案

(1)A  D

(2) 南回归线以南

(3)(0°,90°E)    18点 

题目分析:(1)甲图晨昏线与极圈相切,北极圈内出现极夜,南极圈内出现极昼,则判断此时为北半球冬至日;乙图晨昏线与极点,且北京昼变短夜变长,判断太阳直射点正向南移,故判断此时为北半球秋分日,结合公转轨道图上的太阳直射点位置,A位置太阳直射点位于南回归线上,故判断为北半球冬至日;C位置太阳直射点位于北回归线上,则表示北半球夏至日;则B表示春分日,D表示秋分日。(2)甲图太阳直射点位于南回归线上,则南回归线以南地区正午太阳高度达一年中最大值。(3)太阳直射点的坐标即有经度又有纬度,秋分日太阳直射点的纬度为赤道;太阳直射点的经度为正午12时,即图示昼半球的平分线,结合图示的经度分布为90°E。图示180°经线为昏线与赤道的交点上,为18时。

点评:本题难度一般,基础性试题,学生只要掌握公转轨道图示利用太阳直射点的纬度位置判断二分二至日,晨昏线图示上结合晨昏线与经线和纬线的关系判断二分二至日,掌握晨昏线图上时间计算的基本方法:找到6点、18点、12点的位置。

       With the development of science and technology, most of us will comment: "Life is speeding up.

Everyone is getting unwell."

     This may sound like something someone would say today. But in fact, an unknown citizen who lived

in Rome in 53 AD wrote it.

     We all love new inventions. They are exciting, amazing and can even change our lives. But have all

these developments really improve the quality of our lives?

     Picture this, you're rushing to finish your homework on the computer. Your mobile phone rings, a

QQ message from your friend appears on the screen, and the noise from the television is getting louder

and louder. Suddenly the computer goes blank and you lose all your work. Now you have to stay up all

night to get it done. How calm and happy do you feel?

     Inventions have speeded up our lives so much that they often leave us feeling stressed and tired. Why

do you think people who live far away from noisy cities, who have no telephones, no cars, even no

electricity often seem to be happier? Perhaps because they lead simpler lives.

     One family in the UK went "back in time" to see what life was like without all the inventions we have

today.

     The grandparents, with their daughter, and grandsons Benjamin, 10, and Thomas, 7, spent nine weeks

in a 1940s house. They had no washing machine, microwave, computer or mobile phones. The grandmother,

Lynn said,"It was hard physically, but not mentally." She believed life was less materialistic. "The more

things you have the more difficult life becomes." She said. The boys said they found less to fight over, such

as their computer. Benjamin also noticed that his grandmother had changed from being a"trendy,

beer-drinking granny to one who cooked things". Here are some simple ways to beat the stress often caused

by our inventions!

     ●Don't be available all the time. Turn off your mobile phone at certain times of the day. Don't check your

emails every day.

      ●Make sure you spend some time talking to your family. Set aside one evening a week when you don't

turn on the television. Play cards and chat instead.

     ●Get a low-tech hobby. Every day,do something in the old-fashioned way,such as walking to have a

face-to-face meeting instead of using the email or telephone.

     ●Don't worry too much about life-laugh more!
