The Fall of the Berlin Wall
推倒柏林墙

The Berlin Wall was a barrier that existed from 1961 through 1989, constructed by the German Democratic Republic (GDR, East Germany) starting on 13 August 1961, that completely cut off (by land) West Berlin from surrounding East Germany and from East Berlin until it was opened in 1989. The barrier included guard towers placed along large concrete walls, which circumscribed a wide area that contained anti-vehicle trenches, and other defenses.
柏林墙是德国分裂期间(1961—1989)东德政府修筑的边防系统，以将其与东德领土分割开来。柏林墙由德意志民主共和国(东德)于1961年8月13日开始修建，直到1989年间被推倒，在这段时间内它完全切断了西柏林周围的东德和柏林东部。柏林墙是由瞭望塔、混凝土墙、开放地带以及反车壕沟组成的边防设施。

In 1989, a series of radical political changes occurred in the Eastern Bloc, associated with the liberalization of the Eastern Bloc's authoritarian systems and the erosion of political power in the pro-Soviet governments in nearby Poland and Hungary. After several weeks of civil unrest, the East German government announced on 9 November 1989 that all GDR citizens could visit West Germany and West Berlin. Over the next few weeks, euphoric public chipped away parts of the wall. The governments later used industrial equipment to remove most of what was left. Contrary to popular belief the wall's actual demolition did not begin until summer 1990 and was not completed until 1992. The fall of the Berlin Wall paved the way for German reunification, which was formally concluded on 3 October 1990.
1989年，伴随着东欧政权自由化和在波兰、匈牙利周边亲苏政权的瓦解，东欧发生了一系列政治剧变。经过几周的骚乱，东德政府在1989年11月9日宣布，所有的东德公民可以前往西德和西柏林。在接下来的几周内，兴高采烈的人们凿开了部分围墙，政府后来用大型设备清除了剩下的大部分。与普遍认为的观点不同，实际上柏林墙从1990年夏天才开始被推倒，直到1992年才完全结束。推倒柏林墙事实上也为德国于1990年10月3日的重新统一铺平了道路。
