问题 选择题

读某一局部地区的等高线地形示意图,回答问题。

小题1:与图示地形特征较为符合的是

A.四川盆地

B.珠穆朗玛峰

C.白头山天池

D.云贵高原小题2:面最后可能是过AB线所作的地形剖面图的是

A           B               C                  D

小题3:该地区最主要的地质灾害是

A.地震

B.火山喷发

C.滑坡

D.泥石流

答案

小题1:C

小题2:D

小题3:B

小题1:图中等高线地形图中的短横线为示坡线,示坡线是垂直于等高线的短线,用以指示斜坡降低的方向。示坡线通常绘在沿山脊及山谷线的方向上。 与等高线相连的一端指向上坡方向,另一端指向下坡方向。所以图中地形特征为白头山天池。所以本题选择C选项。

小题2:过AB线所作的地形剖面图,从山底开始海拔逐渐升高,然后到达火山口,海拔降低,火山口海拔最低,然后海拔先升高,再降低。如图D所示。所以本题选择D选项。

小题3:通过图中等高线判断。图中为火山地貌。火山地貌容易发生的地质灾害是火山喷发。一般山区可能有滑坡、泥石流等地质灾害,火山喷发能引起地震。但是该地区最主要的地质灾害是火山喷发。所以本题选择B选项。

It’s a typical Snoopy card: cheerful message, bright colors, though a little yellow and faded now. Though I’ve received fancier, more expensive cards over the years, this is the only one I’ve saved. One summer, it spoke volumes to me.
I received it during the first June I faced as a widow to raise two teenage daughters alone. In all the emotional confusion of this sudden single parent- hood, I was overwhelmed with, of all things, the simplest housework: leaky taps, oil’ changes, even barbecues (烧烤). Those had always been my husband’s jobs. I was embarrassed every time I hit my thumb with a hammer or couldn’t get the lawnmower (割草机) started. My uncertain at- tempts only fueled the fear inside me: How could I be both a father and mother to my girls Clearly, I lacked the tools and skills.
On this particular morning, my girls pushed me into the living room to see something. (I prayed it wasn’t another repair job). The "something" turned out to be an envelope and several wrapped bundles on the carpet. My puzzlement must have been plain as I gazed from the colorful packages to my daughters’ bright faces.
"Go ahead! Open them!" they urged. As I unwrapped the packages, I discovered a small barbecue grill (烧烤架) and all the necessary objects in- eluding a green kitchen glove with a frog pattern on it.
"But why" I asked.
"Happy Father’s Day!" they shouted together.
"Moms don’t get presents on Father’s Day," I protested.
"You forgot to open the card," Jane reminded. I pulled it from the envelope. There sat Snoopy, on top of his dog house, merrily wishing me a Happy Father’s Day. "Because," the girls said, "you’ve been a father and mother to us. Why shouldn’t you be remembered on Father’s Day"
As I fought back tears, I realized they were right. I wanted to be a "professional" dad, who had the latest tools and knew all the tricks of the trade. The girls only wanted a parent they could count on to be there, day after day, performing repeatedly the maintenance tasks of basic care and love.
The girls are grown now, and they still send me Father’s Day cards, but none of those cards means as much to me as that first one. Its simple message told me being a great parent didn’t require any special tools at all--just a willing worker.

The girls gave their mother a barbecue set probably because

A. it was what their mother wanted
B. it was a proper Father’s Day gift
C. barbecue was their favorite food
D. they wanted their mother to barbecue
