问题 选择题

读地球自转线速度随纬度变化(图甲)和地球公转速度变化(图乙),回答下题。

甲图M点的纬度、乙图N点的月份分别是

A.30° 1月

B.60° 7月

C.60° 1月

D.30° 7月

答案

答案:B

题目分析:本题考查地球自转线速度和地球公转速度的规律。地球自转速度的规律是线速度自赤道向两极递减,赤道最大为1670km/h,两极最小速度为零,南北纬60°的自转线速度为赤道的一半是835km/h。通过图甲可知M点的自转速度是835km/h得出M处纬度应为60°。地球公转速度规律为:每年一月初在近日点公转速度最快,每年七月初在远日点公转速度最慢。通过图乙可知N点公转速度最慢得出N点应位于远日点,对应时间为7月初。

点评:本题难度一般。本题通过地理图像考查地球自转和公转的相关规律,锻炼学生的知识迁移能力和对地理图像的分析能力。

     I love it at night. It's peaceful. And when it cools down I sometimes do some ironing. I don't really care

for it. I work full-time and I am too busy for most housework. I remember the old woman who taught me

to iron. I was about 15 and I had to get a job taking care of a woman to make a living. She had been an

able-bodied, healthy woman until the accident that caused her to be paralyzed.

     The woman sat in an electric wheelchair all day. She could only move her head and arms. She would tell

me how to do things. She would teach me in great detail on the correct ways to do things. Her home was

perfect and beautiful. She would follow me around in her electric wheelchair to make sure I did everything

exactly right. I'm sure she had been a perfect homemaker. She would have me fold (折叠) everything,

including socks. I would complain silently and wish terrible things on her. She taught me the right way to

make the bed. I know sometimes she'd get frustrated (沮丧) and impatient with me. I knew she wanted to

do it herself. But she never shouted or scolded. She only insisted I do it right. I didn't like it much, but I did

it.

     Today I can iron pretty well. I know where to start on a shirt and the right way to do the trousers. Now

when I think about it, I don't think she is an old lady. I think she might have been about my age now. Anyway,

when I iron, I think of her and silently thank her for all the things I learned.
