文章講解：

BLURB:

用心良苦，就怕我們看不明白。

para 1:

line 1-12

用一些城市的例子表明人口流動(dòng)的趨勢(shì)不同地方不同；

line 12-25

“天平”開始傾斜，關(guān)注城市人口外流；

25-35

不代表人們不愿意回來(lái)

para 2:

人們要走早都走了，何必等到現(xiàn)在；

para 3:?

點(diǎn)題~需要adjust

para 4:?

早期理論；

para 5：

這個(gè)理論基本還是對(duì)的；

para 6:?

但是因?yàn)楝F(xiàn)代城市的發(fā)展模式不同，現(xiàn)在開始慢慢不適用了~

題型解析：

17 B 選項(xiàng)有迷惑。但需要在提到題干中1974 American cities之后才是題點(diǎn)。

19 這一題還是出的有水平的。對(duì)應(yīng)line 11的轉(zhuǎn)折，讀如首句。

背景拓展：

Alan Ehrenhalt?was the executive editor of Governing magazine from 1990 to 2009. He is the author of The United States of Ambition, The Lost City, and Democracy in the Mirror. In 2000, he was the recipient of the American Political Science Association's Carey McWilliams Award for distinguished contributions to the field of political science by a journalist. He is currently Information Director at the Pew Center on the States in Washington, D.C.

Eye-opening and thoroughly engaging, this is an indispensible look at American urban/suburban society and its future.
In?The Great Inversion,?Alan Ehrenhalt, one of our leading urbanologists, reveals how the roles of America’s cities and suburbs are changing places—young adults and affluent retirees moving in, while immigrants and the less affluent are moving out—and addresses the implications of these shifts for the future of our society.
