下图中a为纬线,P、Q两地经度相同,相距800千米。完成下列各题。

小题1:若Q点5时30分日出,a点的纬度为15°,这时的月份可能是(    )

A.12月

B.2月

C.6月

D.10月小题2:若P地19时太阳已落,Q地仍夕阳西下,这一季节(    )

B.美国大平原麦翻金浪

C.潘帕斯草原绿野千里

D.尼罗河进入丰水期

答案

小题1:A  

小题2:C

题目分析:

小题1:结合教材中日照图资料分析,在夏至日20°N昼长约13时13分,40°N昼长14时51分,60°N昼长约18时29分。若Q点5时30分日出,则Q地昼长为13时,说明Q地此时位于当地的夏半年,纬度大约为20° 。a点的纬度为15°,Q地约为20°,所以Q地位于南半球,南半球夏季且季节接近冬至日。所以A对。2月份太阳直射点接近赤道,20°纬线的昼长与赤道昼长接近,不会达到13小时,B错。6月份时北半球夏季,南半球昼长小于12小时,C错。10月份太阳直射点离赤道也较近,20°纬线的昼长小于13小时,接近12小时。D错。

小题2:若Q地19时夕阳西下,说明Q地昼长约14小时,结合上题分析,此时南半球是夏季,且是冬至日附近日期,昼长大于夜长,且差距较大。此时北半球是冬季,长江流域油菜花是在春季盛开,此时昼夜长短相差不大,A错。美国大平原麦翻金浪是在北半球夏季,B错。潘帕斯草原位于南半球,此时正是草木茂盛,绿野千里,C对。尼罗河在北半球 夏季进入丰水期,冬季进入枯水期,D错。

    I'll never forget that summer day in 1965 when my mother suddenly died. Later that after-noon, a police
officer came to ask my father' s permission (允许) for the hospital to   1   mother's valve (心脏瓣膜). I
shouted and cried. At fourteen I   2   couldn't understand why anyone would take it away from a person I 
  3   But my father told him. "Yes."
    "Linda," he said quietly putting his arms   4   me, "the greatest thing you can give is a part of yourself.
Your mother and I decided   5   that if we can make a difference in just one person' s   6   after we die,

    My father died and we donated his eyes   9   he had wanted. Three days later,my daughter said, "Mum,
I'm so  10  what you did for grandpa." At that moment I realized that my father gave much more than his

    That was love.
