问题 选择题

我国某中学地理兴趣小组,经过课外调查得到某一河流各月平均径流数据,绘制成下图 (图中数字表示月份,同心圆数值自内向外增大)。据此完成下列问题。 

 

小题1:关于该河流水文特征的叙述,正确的是(    )

A.一年有两次汛期,汛期时间长

B.冬季有结冰期,出现断流现象

C.径流量大,泥沙含量大

D.水位不稳定,季节变化大小题2:关于该河流域农业发展的相关分析,正确的是

A.热量不足是制约农业生产的主要因素

B.冬小麦种植面积广,是我国冬小麦主产区之一

C.农产品单产高,商品率低

D.土壤盐碱化是农业生产面临的主要问题

答案

小题1:D 

小题2:A

题目分析:

小题1:由图可知该河流一年有两次汛期,一次是在3、4月份属于春汛,一次是在7、8月份属于夏汛,但是汛期时间都较短;该河流水位不稳定,季节变化大,河流各月的径流量均大于零,所以没有出现断流现象;图中没有具体径流量的数值,河流径流量的大小不能够确定,故选项D正确。

小题2:根据中国不同区域河流的水文特征,结合读图可知该河流应当位于中国东北地区。东北地区所处纬度较高,温度较低,因而热量不足是制约农业生产的主要因素;该地区大部分属于中温带,春小麦种植面积广,是我国春小麦主产区之一;东北地区地广人稀,人均粮食占有量多,商品率高;黑土流失、湿地减少是农业生产面临的主要问题,故选项A正确。

    I was fifteen months old, a happy kid until the day I fell. It was a   1   fall. I landed
on a glass rabbit which cut my eye badly enough to make it blind. Trying to save the
eye, the doctors stitched (缝合) the eyeball together where it was   2  , leaving a big
ugly scar (疤痕) in the middle of my eye. The attempt   3  , but my mother, in all of
her wisdom, found another doctor who knew that if the eye were removed   4  , my
face would grow up badly distorted (扭曲),   5   my scarred, sightless, cloudy and
gray eye lived on with me. As I grew,this sightless eye in so many ways   6   me.
    I walked with my face looking at the   7   so that people would not see the   8   me.
Yet my mother would say to me, at every turn, "Hold your head up high and   9   the
world. If you hold your head up high, it will be OK, and people will see your  10  soul."
She continued this  11  whenever I was trying to hide.
    Mama's words were of great help for me to face the world  12 . As a teenager, even
though I tended to look down to hide my shame, I found that sometime when I held my
head up high and let people know me, they  13  me. In high school, I was  14  both
academically and socially. I was  15  elected class president. My mother's words helped
me begin to realize that by letting people look at my face, I let them  16  the intelligence
and beauty behind both eyes, even if they couldn't see it on the  17 .
    Now I'm a happy wife and great mother. The message "Hold your head up high" has
been  18  many times in my  19  home. Each of my children has felt  20  invitation, and
the gift my mother gave me has lived on in another generation.
