When my uncle was young, he answered the call and volunteered to work on that distant island. My uncle worked hard in the day. In his free time, he went on studying the characteristics of those plants. He even had some samples placed in his bedroom. It was just at that time that he began to think about how they evolved from their ancestors. While his study generated no income, he was crazy about it.
He often used some primitive methods to carry out his experiments, detecting how the seeds grew into some tall plants. There was a time when the number of those plants was on the decline and human beings were to blame . He managed to find out the reason and came up with a new way to solve the problem. Later, he achieved a lot in this field. Many people had suspected his talent, but he succeeded！He was absolutely a legend！

The effect filled me with a hopeless sadness. Instead of a sky of blue, filled with stars, there was above me a heavy roof of granite①， which seemed to crush② me. Looking around, I began to think of the theory of the English captain who③ compared the Earth to a vast hollow sphere④， inside of which⑤ the air remained bright by means of⑥ atmospheric pressure, while⑦ two stars, Pluto and Proserpine, circled there in their mysterious orbits. After all, suppose the old fellow was right!
In truth, we were imprisoned⑧—trapped as it were, in a vast space. Its width was impossible to make out⑨； the shore, on either side, widening rapidly until lost to sight; while its length was equally uncertain. A haze⑩ on the distant horizon blocked our view. As to its height, we could see that it must be many miles to the roof. Looking upwards ， it was impossible to discover where the incredible roof began. The lowest of the clouds must have been floating 2，000 yards up, higher than those above the Earth's surface, due to the extreme density of the air.

一周前他沿着街道走着，看到一个正在哭泣的女孩。
__________________________________________________________
Clouds.
Walking along the street a week ago, he saw a girl who was crying.
【识文知意】　那种影响让我充满了绝望的悲伤。在我的头顶上，不再是满天繁星点缀的蓝天，而是一块沉重的花岗岩屋顶，仿佛要将我压垮。环顾四周，我开始想起那个英国船长的理论，他把地球比作一个巨大的空心球，在这个球体内部，由于大气压的作用，空气保持明亮，而冥王星和普洛塞耳皮娜这两颗星星则在其神秘的轨道上环绕运行。毕竟，假设那个老兄说的是对的。
事实上，我们被囚禁了——被困在一个广阔的空间里。这个空间的宽度无法估量；两岸的海岸迅速扩大，直至消失在视线之外；而它的长度也同样不确定。远处地平线上的一层薄雾阻挡了我们的视线。至于它的高度，我们可以看到，离屋顶一定有数英里之遥。抬头望去，无法发现那令人难以置信的屋顶是从哪里开始的。由于空气极度稠密，最低的云层一定漂浮在2 000码的高空，比地球表面的云层还要高。
