地质构造是指岩层在地壳运动作用下,引起地壳变形变位,保留在岩层中的构造,包括褶皱构造、断层构造两种。下列关于地质构造的说法,正确的是( )。

A.褶皱是地壳的垂直运动,产生的挤压使岩层发生弯曲变形
B.褶皱地带易发育成谷地或低地,典型的如渭河平原、汾河谷地等
C.背斜是岩层上凸的弯曲,向斜是岩层下凹的弯曲;背斜岩层中间新两端老,向斜则中间老两端新
D.断层一侧上升的岩块,容易形成块状山地或高地,例如华山、庐山

答案

参考答案:D

解析: 褶皱是地壳的.水平运动,产生的挤压使岩层发生弯曲变形。断层是地壳的垂直运动,使岩层发生断裂,断裂面两侧岩块有明显错动,故A项错误。断层一侧上升的岩块,容易形成块状山地或高地,例如华山、庐山;另一侧则常形成谷地或低地,如我国的渭河平原、汾河谷地等,故B项错误,D项正确。背斜岩层中间老两端新,向斜则中间新两端老,故C项错误。本题正确答案为D。

What is it that makes people laugh? More than two thousand years ago the ancient Greek philosopher (哲学家) Aristotle defined (定义) jokes as the pleasure that results from a feeling of triumph by showing we’re better than someone else in a certain way. According to Aristotle and many other philosophers,all jokes depend mainly on showing inferiority in another person or group of persons — that is,putting it clearly,on showing that they are worse off than ourselves. Jokes raise our good opinion of ourselves at someone else’s expense.

Showing how much better than other people we are is only one reason we like jokes. Someone may also use a joke to express their anger or their cruelty (残酷)or any other kind of action that is not acceptable to us. We feel free to laugh when we hear about someone sliding on a banana skin. The joke lets us express those attitudes which are usually unacceptable to society. This is probably the reason why some of the jokes,especially those involving cruelty,are so popular with certain people.

Besides,all jokes depend on our enjoyment of laughing at something that is strange and out of place because it’s different from things which are happening around it. The same situation can be either sad or pleasant,depending entirely on how strange and out of place it is. If a girl in a bathing suit falls into a swimming pool,we don’t laugh because nothing unusual has happened. But if a man in a smart suit falls in,the situation is at once unusual in a pleasant way and we laugh. A good joke-teller will always try to build up a situation in which one thing is expected until something unexpected suddenly happens,and so we laugh.
