读某大陆沿海地区等高线及等深线图,回答题。

小题1:当地欲建一港口,以此作为启动该地区经济发展的钥匙,港口最宜建在图中:

A.①地

B.②地

C.③地

D.④地小题2:该地区某小镇周边地形状况如右图,图中两条小河的流量相当。进入小镇的引水线最合理的是

A.① 

B.②

C.③ 

D.④

答案

小题1:B

小题2:D

小题1:题目分析:港口建设应考虑陆域和水域两方面条件,水域条件考虑应建于海湾地区,可避风浪;等深线较密集,则水深利于建港口;从陆域考虑,应布局于陆上地域平坦开阔地带,适宜建港。比较图示四地,①地等深线分布稀疏,水浅;③地位于岛上,地域面积狭小,且地形起伏大;④地水浅。故②地最适宜。

点评:本题难度一般,解题的关键是掌握影响港口建设的水域和陆域条件的综合因素,并能结合图示的海陆分布和等高线、等深线分布判断。

小题2:题目分析:引水线建设应考虑地势条件,从高处向低处引水可自流,并考虑线路长短,减少工程量。注意河流流向与等高线凸向的相反,可判断河流的流向。故比较四条线路,④线路最合理。

点评:本题难度一般,掌握引水线建设的主要影响因素和利用河流与等高线凸向的关系判断地势高低是解题的关键。对于此类试题,学生应在平时的学习中加强一般规律的总结和归纳。

     Dreams are expressions of thoughts, feelings and events that pass through our mind while we are sleeping.

Everybody dreams. But only some people remember their dreams. Our dreams often include all the senses-smells, sounds, sights, tastes and things we touch. We dream in colour. Sometimes we dream the same dream over

and over again. These repeated dreams are often unpleasant. They may even be nightmares-bad dreams that

frighten us.

     Early in the twentieth century, two famous scientists developed their personal ideas about dreams.

Austrian psychiatrist Sigmund Freud published (出版) a book called "The Interpretation (诠释) of Dreams"

in 1900. Freud believed people often dream about things they want but can't have. These dreams

often have something to do with sex and aggression (侵犯行为). Swiss psychiatrist Carl Jung worked

closely with Freud for several years, but he believed dreams could help people grow and understand

themselves. He believed dreams provide solutions (解决办法) to problems we face when we are awake.

He didn't believe dreams hide our feelings about sex or aggression. Today we know more about the science

of dreaming because researchers can take pictures of people's brains while they are sleeping.

     Other researchers are studying how dreaming helps our bodies work with problems and very sad emotions. Robert Stick gold is a professor of psychiatry at Harvard University in Massachusetts. Doctor Stick gold says

that when we dream, the brain is trying to make sense of the world. He does not agree with Sigmund Freud

that dreaming is the way we express our hidden feelings and desire (愿望).

      Scientists believe it is important to keep researching dreams. Doctor Stick gold says it has been more than

one hundred years since Sigmund Freud published his important book about dreaming. Yet there is still no agreement on exactly how the brain works when we are dreaming or why we dream.
