2008年9月27日北京时间16时44分,太阳非常平静,航天员翟志刚走出“神舟七号”舱门,实现了中国历史上的首次太空行走。下图是“神舟七号绕地球运行轨道示意图”,读图完成5-7题。

5.宇航员翟志刚出舱时,观察到的现象符合事实的是

A.手中五星红旗,迎风招展      B.阳光十分灿烂,天空蔚蓝

C.太阳照射下,船体明亮        D.众多流星,划过夜空

6.飞船绕地球运行周期是90分钟,图示时刻地球上“180°经线”刚好正对着地球轨道上的远日点。飞船绕地球一周后,正对近日点的经线度数是

A.157.5°W     B.22.5°W          C.22.5°E      D.157.5°E

7.图乙为神舟七号轨道在地球表面上的投影。则飞船连续两次在赤道上的投影间距大约为

A.2200千米    B.2500千米    C.2800千米    D.3000千米

答案

5.C  6.B  7.B

5.高层大气接近真空,无气流,无散射,无流星现象。

6.飞船绕地球运行周期是90分钟,则一天内绕地16圈,其运行轨迹在地面的投影,每圈跨经度22.5度,地球自西向东自转,轨迹自东向西移动,故飞船绕地球一周后,正对远日点的经线度数是157.5°E,正对近日点的经线度数是22.5°W。

7. 又上题可知,飞船绕地球运行,每圈跨经度22.5度,即飞船连续两次在赤道上的投影间距为22.5×111≈2500千米。

     One day, when I was in high school, I saw a kid named Kyle from my class walking home from school
with all his books, I thought to myself, "  1   would anyone bring home all his books for the weekend? He
must really be   2  ." As I was walking, I saw several kids running toward him. They ran at him,   3   all his
books out of his arms and he fell down in the dirt. His glasses went   4   and landed in the grass. He looked
up and I saw this terrible sadness in his eyes.
     My   5   went out to him. So, I ran over to him.   6   I handed him his glasses, he looked at me and said,
"Hey, thanks!" There was a big smile on his face.
     I helped him pick up his books, and asked him where he lived. As it   7  , he lived near me. We talked all
the way home. I didn't see him before as he had gone to a private school. Over the next four years, Kyle and
I became best friends.
     Kyle was the   8   student of our class, one of those guys that really found themselves during high school.
Therefore he had the   9   to prepare a  10  speech. On the graduation day, I could see that he was  11 . So,
I patted him on the back and said, "Hey, big guy, you'll be  12 !" He looked at me and smiled.
     He cleared his throat, and began. "Graduation is a time to  13  those who helped you make it through those
  14  years. Your parents, your teachers… but mostly your friends. I am here to tell all of you that being a
friend to someone is the best  15  you can give him."
     I just looked at my friend with  16  as he told the story of the first day we met. He had planned to  17  
himself over the weekend and was carrying his books home. "Thankfully, nothing happened. My friend  18  
me from doing the unspeakable."
     Not until that moment did I realize that you should never underestimate (低估) the  19  of your actions.
With one small gesture you can  20  a person's life. For better or for worse.
