A very little boy was spending his Saturday morning playing in his sandbox. He had with him a plastic pail (桶) and a shiny, red plastic shovel (铲). In the  1  of creating roads and tunnels in the sand, he   2  a large rock in the middle of the sandbox.
The boy dug around the rock,  3  to move it off the dirt. At first, he wanted to carry it out of the sandbox with his hands; however, it was too heavy. Later, with much   4 , he pushed the rock across the sandbox by   5  his hands. When the boy got the rock to the   6  of the sandbox, he found that he couldn’t roll it up and   7  the little wall.   8 , the little boy pushed, but every time he thought he had made some   9 , the rock tipped (翻滚) and then fell back into the sandbox. The little boy pushed and pushed, but his only   10  was to have the rock roll back.
Finally he  11  tears. All this time the boy’s father watched from his living room window   12  the drama was unfolded. The moment the tears fell, a large   13  appeared across the sandbox. It was the boy’s father. Gently but   14 , he said, “Son, why didn’t you use all the strength that you had?”

Indonesia is known as the country of islands. It has 17,508 islands. But in recent years, the popular tourist destination has lost some of its shine.

Due to rising sea levels caused by global warming, 24 Indonesian islands have gone under the sea. Scientists say 2,000 more will disappear before 2030. In the past three years, the Southeast Asian nation also witnessed its islands destroyed by a tsunami(海啸) and typhoons.

“If no measures are taken to fight climate change, the beautiful islands will go forever,” scientists told environmental ministers from about 190 countries at a UN climate change meeting.

This week they are meeting in Bali, an Indonesian island. They are trying to reach a deal to cut the world’s emissions (排放) of CO2 , which makes the Earth warmer.

Indonesia is not alone. This year has seen more extreme weather hit the world. Canada and US suffered heavy storms and typhoons, while Australians were caught in the heaviest drought in a century.

In China, the average temperature this year went up by 1.2oC from last year, reaching the highest on record since 1951.

However, other parts of the country got too much rain. More than 700 people were killed in floods, landslides and storms. “These weather extremes are the more obvious effects of global warming,” said Song Lianchun, a climate expert.

Scientists say time is running out. To escape from the worst effects, global CO2 emissions need to be cut from the levels they were at in 2000 by 50 to 85 percent by 2050.

But in recent years climate change talks have been bogged down by arguments over who will pay the bill for cleaner technology. Developing countries are worried that the cut in emissions will slow their economic development.

“China will play a responsible and constructive rule in the meeting,” said Chinese Premier Wen Jiabao. The nation is now the world’s second largest greenhouse gas emitter(排放者). “However, developed nations should help developing nations deal with the global issue.”

A. who should be responsible for causing climate change

B. who will pay for the cleaner technology needed 

C. whether developed countries should help developing ones

D. whether developing countries should cut emissions of CO2

56. What is China’s attitude towards dealing with problems of climate change?

A. China will pay for the cleaner technology.

B. China will take an active part in dealing with climate change.
