没有围墙阻挡，是一个很大的空地。

Videos posted on Youtube showed a small but determined group of protesters using chains and long metal pipes to bring down a section of concrete wall blocking one of the entrances to Cairo's Tahrir Square.

上传到Youtube的这段视频显示一个规模虽小但信心十足的群体抗议者们使用链子和长金属棒来破坏阻挡着开罗的解放广场入口的一段混凝土墙。

These long and towering peaks effectively act like a colossal wall blocking most of the moisture blowing in on clouds from the Pacific Ocean and therefore preventing most rain from passing beyond them towards the Arid Plains of the East.

这些又长又高的山峰就像一堵巨大的墙，有效地阻挡了从太平洋吹到云层中的大部分水分，从而阻止了大部分雨水越过山峰流向东部的干旱平原。
