美国而言,虽然美国是美国各州(State/Commonwealth)组成的联邦,但是有些州之间
的经济、文化是十分相似的,而某些州和另一些州的经济和文化上又有明显差异,这些
差异之大甚至可以与一些欧洲邻国之间的经济文化差异相提并论。作者就此类现象,提

显著的经济和文化差异。
此外,加罗先生还指出,在研究北美洲人文地理时,根据国家和州之间的政区划分探讨
文化异同是没有现实意义的。只有根据经济和文化背景,才能够真正理解北美洲社会的
人文地理差异。梅维尔州立大学(英语:Mayville State University)的保罗·默尔

President Obama has suggested in his last 147 television appearances that he

1. If you care to or able to read and comprehend the whole story, you would
find out that the perpetrator is an Indian student, not a Chinese one, much
to your disappointment.
2. This is simply a tasteless high school prank that has tickled the over
sensitive nerves of the local media, not mainstream media. If you google the
words "monta vista high school antisemitic", you will find only Bay Area
medias covering this story, so you are blowing this way out of proportion.
3. You need to calm the h... 阅读全帖

多谢jiawa的详细信息。
我摄影的知识很有限,差不多就是物理课本上的那些知识。我的理解就是拍人物的镜头

I think Saturday's game was an aberration for U. It was not the U's night.

field goal and the fumble killed U's players inspirations. Much like FSU-OU
game. After Ponder's right arm got hit (similar to Alabama-Texas NC game)
on second drive and he couldn't threw accurate passes, everything went down
hill.
The key is how U's players rebound from this game. FSU coaches did excellent
job to get players confidence back. If ... 阅读全帖

相机和镜头不入会长的法眼。这个叫chromatic aberration
