Question

    The endangered pandas in Qinling Mountains might face a new threat: the loss of their food—bamboo, which makes up 99% of their meals.

Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature and Climate Change warned that they may soon find their food gone because most of the bamboo in Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.

A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature increases 3.5 degrees worldwide by the end of the century.” said Liu Jianguo, one of the report’s authors. He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening around the world.”

In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.

“But it is far from being enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from World Wildlife Fund but not a member of the team.

The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of the Chinas wild panda population. In addition, about 375 are living in research centers and zoos in China.

【解析】

本文是说明文。文章讲述了秦岭大熊猫的食物来源——竹子受到威胁。由于气候变暖，到本世纪末，秦岭的大部分竹子也许会遭遇灭顶之灾。研究者们呼吁采取措施进行保护。

1.主旨大意题。根据第一段The endangered pandas in Qinling Mountains might face a new threat: the loss of their food—bamboo, which makes up 99% of their meals.可知，首段点明主题文章，重点讲述了秦岭大熊猫的食物来源—竹子受到威胁。这对于大熊猫生存来说是一个新的威胁。所以“大熊猫面临的新威胁”为最佳标题。故选B。

2.推理判断题。根据第一段The endangered pandas in Qinling Mountains might face a new threat: the loss of their food—bamboo, which makes up 99% of their meals.可知，秦岭濒危的大熊猫可能面临一个新的威胁：失去它们的食物竹子，竹子构成了它们99%的食物。由此推断出秦岭的大部分竹子也许会遭遇灭顶之灾，可能会消失。故选C。

3.推理判断题。根据第三段中He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening around the world.”可知，Liu Jianguo说即使各个国家都遵守巴黎协定，到2100年全球气温会增长3.5度。可以推断出Liu Jianguo认为控制温度上升很难。故选D。

4.细节理解题。根据最后一段The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of the Chinas wild panda population.可知，秦岭山上有260只熊猫，占中国野生熊猫总数的13%，中国野生熊猫的总数是通过260除以13%得2000计算出的。故选A。
