L17-2：The longest suspension bridge in the world

Two great towers support four huge cables. The towers are built on immense underwater platforms make of steel and concrete. The platforms extend to a depth of over 100 feet under the sea. These alone took sixteen months to build. Above the surface of the water, the towers rise to a height of nearly 700 feet. They support the cables from which the bridge has been suspended. Each of the four cables contains 26,108 lengths of wire. It has been estimated that if the bridge were packed with cars, it would still only be carrying a third of its total capacity. However, size and strength are not the only important things about this bridge. Despite its immensity, it is both simple and elegant, fulfilling its designer's dream to create 'an enormous object drawn as faintly as possible'.

练习感悟：

今天能不能回到深圳已经无法确定了，而我能做的，就是尽可能把各种各样的琐碎事情以最快速度做完，能多完成一些本该计划在深圳完成的事情。

我真的好想念那个家，那个大班桌。可能回到深圳，做那些脑力劳动上最累的事情，才是我永恒的归宿。我是属于这个肮脏而复杂美丽的世界的，便只能好好努力了。
