  1. How did Columbus think of the rainforest? He thought it was most beautiful and quite different from that in Europe, with flowers and fruits, and little birds singing sweetly. 2 What does the sentence “It remains hard to beat.” mean? It means that no one else has ever given a better description of the rainforest than Columbus.
  3. What do you know about London forty-five million years ago according to this paragraph. It was covered with rainforests forty-five million years ago.

  4. What do you know about the rainforests in the world today? The rainforests cover no more than seven percent of the earth’s surface today.
  5. What is “the secondary growth”? why is it called “the secondary growth”? “The secondary growth” refers to the new growth after the original growth has been destroyed.
  6. How does the modern world speed up the process of destruction? Modern technology doubtlessly increases efficiency when people try to cut down trees.

  7. Who is to blame for the destruction? It is the human beings that are to blame for such destruction.
  8. What can be done if we want to control the buildup of temperature We must protect the rainforests as well as the trees. And at the same time we should do our best to bring back the rainforests.
Rainforests are one of the most valuable natural gifts in the world, but now they are dying out.What has has happened?…
Paradise lost?
? Christopher Columbus said that he had never seen anything so beautiful, trees “beautiful and green, different from ours, with flowers and fruits and little birds which sing very sweetly.”
The great navigator’s impression is the first known written description of a rainforest. It remains hard to beat. Rainforests are extraordinarily beautiful,but the beauty is fragile. Forty-five million years ago rainforests covered the city of London, and rainforests were then over 30 million years old. That makes them the oldest communities of living things on the planet.
Today the world rainforests cover no more than seven per cent of its surface even though they still contain more than 50 percent of the earth’s living species. The greatest and most famous of all remaining rainforests is found in Brazil, whose Amazon Basin, with its thousands of small and large streams, is almost totally covered by trees. The rest of the world’rainforests can only be found in West Africa, South-East Asia, and the pacific islands.
When the rainforests are cleared, they take a long time to come back. A few rapidly growing species quickly become established, but this secondary growth, as it is called, is far less rich and varied.
Who is really to blame? It is the modern world that has speeded up the process of destruction. Once, it took a team of men a whole day to cut down a giant tree. Now, a single man can do it in ten minutes. Since 1945 half of the world’s rainforests have come down.
?
It is people themselves who are the biggest cause of destruction. The wealthy own the best land, and the poor of the world are forced to find land where they can find it?and it is there, under the trees. So the trees are removed.
When trees disappear from the land, the water sources suddenly disappear. The land itself washes away, either becoming very poor or complete desert. Worse still, the climate is likely to change as the trees are no longer there to absorb the carbon dioxide in the atmosphere. The gas rises and traps the sun’s heat in much the same way as the glass of a greenhouse, leading to a slow but steady build-up of temperature.
What is the way out, then? Both the problem and the solution seem to be economic. Governments still need money to pay their families, and companies still need to make profits. On the other hand, by purchasing renewable rainforest products, and demanding sustainable harvesting of rainforest resources, we all can be part of the solution and it is human beings that will be saved.

热带雨林是大自然赐予我们的最珍贵的礼物之一, 但现在它们正在逐渐消失。这到底是怎麽回事 呢?。。。。。。 ? 克里斯托弗。哥伦布曾说他从未看见过比热带雨林 更美丽的地方,那里的树木“青翠欲滴,不同于我们 的树木,开满鲜花,挂满果实。。。小鸟在树上婉转 地歌唱。” ? 这位伟大的航海家对热带雨林的印象是已知的最早 的文字描述。后人记载总显得逊色。热带雨林异乎寻 常的美丽,然而这份美丽却是脆弱的。 ? 4500万年前,热带雨林覆盖着整个伦敦城的面积, 那时他们就有3千万年的历史了。因此,热带雨林成为 这个星球上最古老的群居生物。
? 目前世界各地的热带雨林覆盖面积仅为地球表面的百 分之七,而其拥有的地球上活着的生物物种则超过百 分之五十。在所有的热带雨林中,最壮观、最著名的 是在巴西发现的热带雨林。分布着成千上万条大小溪 流的亚马逊盆地,几乎完全被树林所覆盖。其余的热 带雨林主要分布在西非、东南亚和太平洋诸岛。 ? 砍伐一空的热带雨林需要很长时间才能重新长成。少 数生长较快的物种会很快长起来,然而这种次生林, 正如它的名字一样,其物种要贫乏的多。 ? 实际上应该归咎于谁呢?正是现代世界加快了这种毁 坏的进程。过去砍倒一棵大树需要一群人花一整天时 间。而现在只需要一个人在十分钟内就能完成。自 1945年以来,世界上的热带雨林已减少一半。
? 恰恰是人类自身成了破坏热带雨林的罪魁祸首。富人占有了最好 的土地,世界上穷人被迫去寻找他们所能找到的土地??即树下 的土地。于是,树木被砍掉了。 ? 树木从大地消失之后,水源也突然消失了。泥土本身被水冲走, 土地要麽变的非常贫瘠,要麽完全成了沙漠。更糟糕的是,这些 地方因为没有树木吸收大气层中的二氧化碳,气候可能随之发生 变化。二氧化碳在大气层中集聚起来,像温室的玻璃一样吸收太 阳的热量,导致气温缓慢而稳定地上升。 ? 那麽,出路何在呢?问题的存在与解决似乎都和经济有关。政 府仍然需要钱来还债,移民仍然需要钱来养家糊口,而公司也仍 然需要赢利。此外,如果我们购买可再生的雨林产品,坚持雨林 资源的可持续利用,我们就已经部分地解决了问题,而人类本身 也得到了拯救。
