构建关联图可从整体角度把握地理事物的内在联系,是学习地理的方法之一。读图2、图3,回答问题。

小题1:图2中各箭头表示太阳、地面、大气、宇宙空间的热力作用。青藏高原和四川盆地纬度位置相当,下列叙述正确的是

A.青藏高原的年平均气温较低,与①的数值大小有关

B.四川盆地的年太阳总辐射量较小,与②的数值大小有关

C.四川盆地的年平均气温较高,与③的数值大小有关

D.青藏高原的年太阳总辐射较大,与④的数值大小有关小题2:图3为“地壳物质循环简图”。各箭头表示方向,①②③④表示各类地质作用。下列叙述正确的是

A.大理岩属于甲类岩石

B.乙、丙类岩石具有层理构造并含有化石

C.断层形成与①有关

D.②③④属于内力作用

答案

小题1:C

小题2:D

题目分析:

本题以平时学习基础知识的关联图为条件,考查学生对相关知识的理解。

小题1:表示的是大气受热过程的关联图,其中①表示太阳辐射,②表示地面辐射,③表示大气逆辐射,④大气射向宇宙空间的能量。青藏高原年平均温度较低,与海拔较高有关,A项错;四川盆地年太阳辐射量较小,主要因为云量多,B项错;青藏高原的年太阳总辐射量较大,主要与空气稀薄,大气对太阳辐射的削弱作用小,D项错;四川盆地的年平均气温较高,与大气逆辐射强相关,C项正确。

小题2:中“地壳物质循环简图”, ①表示固结成岩,②上升冷却凝固,③重熔再生,④变质作用,甲属于沉积岩,乙属于变质岩,丙属于侵入型岩浆岩。大理岩属于变质岩,乙类,A项错;变质岩、岩浆岩没有化石,B项错;D项正确。

点评:本题源于基础知识学习过程中的关联图,考查对基础的理解,同时注意对应好题目中图形中的序号表示的意思。

After my husband died, my world crashed around me. My six children were 10, nine, eight, six, three and 18 months, and I was overwhelmed with the responsibilities of earning a living, caring for the children and simply keeping my head above water.

I was fortunate to find a wonderful housekeeper to care for the children during the week, but from Friday nights to Monday mornings, the children and I were alone, and frankly I was uneasy. Every unusual noise or any late-night phone call filled me with fear. I felt incredibly alone.

One Friday evening I came home from work to find a big beautiful German shepherd(牧羊犬) on our doorstep. It was obvious he wanted to make the house his home. The children took an instant liking to "German" and begged me to let him in. I agreed to let him sleep in the basement until the next day. That night I slept peacefully for the first time in many weeks.

The following morning we made phone calls and checked lost-and-found ads for German’s owner, but with no results. Saturday night he was still with us. 

On Sunday I had planned to take the children on a picnic. Since I thought it best to leave German behind in case his owner came by, we drove off without him. When we stopped to get gas at a local station, we were amazed to see German racing to the gas station after us. He stayed again Sunday night.  

Monday morning I let him out for a run while the children got ready for school. He didn’t come back. We thought we’d never see him again. On Friday evening, German was back again. We took him in, and again he stayed until Monday morning, when our housekeeper arrived. It went like this for almost 10 months. We looked forward to his coming each Monday morning he left home.

Each week, between German's visits, I grew a little braver, but every weekend I enjoyed his company. Then one Monday morning we patted his head and let him out for what turned out to be the last time. He never came back.
