   In a world with limited land, water and other natural resources (资源), the harm from the traditional business model is on the rise. Actually, the past decades has seen more and more forests disappearing and globe becoming increasingly warm. People now realize that this unhealthy situation must be changed, and that we must be able to develop in sustainable (可持续的) ways. That means growth with low carbon or development of sustainable products. In other words, we should keep the earth healthy while using its supply of natural resources.

   Today, sustainable development is a proper trend in many countries. According to a recent study, the global market for low-carbon energy will become three times bigger over the next decades. China, for example, has set its mind on leading that market, hoping to seize chances in the new round of the global energy revolution. It is now trying hard to make full use of wind and solar energy, and is spending a huge amount of money making electric cars and high-speed trains. In addition, we are also seeing great growth in the global markets for sustainable products such as palm oil (棕榈油)，which is produced without cutting down valuable rainforest. In recent years the markets for sustainable products have grown by more than 50%.

   Governments can fully develop the potential of these new markets. First, they can set high targets for reducing carbon emissions (排放) and targets for saving and reusing energy. Besides, stronger arrangement of public resources like forests can also help to speed up the development. Finally, governments can avoid the huge expenses that are taking us in the wrong direction, and redirecting some of those expenses can accelerate the change from traditional model to a sustainable one.

The major challenge of this century is to find ways to meet the needs of growing population within the limits if this single planet. That is no small task, but it offers abundant new chances for sustainable product industries.

68. The traditional business model is harmful because of all the following EXCEPT that ______.

   A. It makes the world warmer                           B. it consumes natural resources

   C. it brings severe damage to forests                    D. it makes growth hard to continue

69. What can we infer from Paragraph 2?

   A. China lacks wind and solar energy.                 

   B. China is the leader of the low-carbon market.

   C. High-speed trains are a low-carbon development.

   D. Palm oil is made at the cost of valuable forests.

70. To full develop the low-carbon markets, government can ______.

   A. cut public expenses                                 B. forbid carbon emission

   C. develop public resources                          D. encourage energy conservation

　　 It was a Sunday and the heavy storm had lasted all night. The morning after the storm, though, was beautiful blue skies, warm air and a calm, inviting sea touching the shore gently.

　　 My father realised it was a good day for fishing and invited my sister and me to go with him. I was only 14 and fishing had never been my thing, but I decided to go all the same. I’m so glad I did.

On the road to the harbour we could see the terrible destruction on the coast, but the harbour itself was in fairly good shape. After all it was protected by the arms of a bay that had only one tiny channel to the sea. As we got on board, we noticed two big humps(脊背) in the distance.

On approaching them, we saw it was a mother whale with her baby. We couldn’t believe it ----there aren’t any whales along the coast here. The storm must have driven them across the ocean into the bay, in which the still water was so badly polluted that nothing could survive.

The little baby whale ----actually as big as our boat----was obviously stuck and could not move. The mother dived under the water and came up suddenly, making big whirlpools(漩涡) and waves.” She’s trying to help her baby, but on the wrong side,” my father said. At this point, my father moved our boat in a semicircle to the other side and, heading the boat towards the baby whale, pushed it gently. With our several gentle pushes the big hump turned over and disappeared under water. Then it swam up right beside its mum. They struggled in their desperate attempts to escape but missed the exit and started heading in the wrong direction. We hurried up to the whales and tried to lead them towards the bay channel. Slowly, they let us lead them, some-times rising from the water right beside us to breathe----and to give us a trusting look with those huge eyes. Once they hit their first part of clean water flowing straight from the sea, the mum gave us a wave with her tail and off they swam into the distance.

In the excitement it had felt like only a few minutes, but we had been with those wonderful animals for almost an hour and a half. That was the simple and lasting beauty of the day, Nearly four decades later, I still look back fondly to that golden day at sea.
