根据下列文字资料回答下面问题

据报:中国的消费增长速度惊人,2003年中国成品钢材消耗量已经大约2.5亿吨,20年增长8倍,为美国、日本、德国和法国钢铁消耗量总和的98.65%,约占世界总消耗量的22.8%;水泥消耗量约8亿吨,约为1983年的8倍,占世界总消耗量的48.9%左右;而能源消耗却占了30%,我国单位产值电能消耗为0.15千瓦时/元,是美国的3倍,日本的5倍,2003年我国电力消费为18043.5亿千瓦时,已经超过日本,居世界第二位,仅低于美国,但中国的GDP占世界的却不到5%。
从资源利用效率来看,以单位GDP产出能源表征的能源利用效率,中国与发达国家差距非常大,日本为1,意大利为1.33,法国为1.5,德国为2.17,英国为2.67,美国为3.5,而中国高达11.5,中国的耗能设备能源利用效率比发达国家普遍低30%~40%,每1000美元GDP排放的二氧化硫:美国为2.3千克。日本为0.3千克,而中国高达18.5千克。
从资源再生角度看,中国人均水资源拥有量仅为世界平均水平的1/4,但水资源利用率比发达国家低50%以上,中国的废旧轮胎再生利用率仅有10%左右,远低于发达国家。

下列说法错误的是( )

A.从资源利用效率来看,我国仍然处于粗放型增长阶段

B.我国能源消耗中存在着严重浪费的现象

C.从技术层面上看,我国经济必须大大提高资源利用效率

D.中国资源重复利用率水平远低于发达国家

Once there was a huge apple tree. A little boy loved to come and play around it every day. He loved the tree and the tree loved to play with him.

Time went by --- the little boy had grown up and he no longer played around the tree every day. One day, the boy came back to the tree and he looked sad. “Come and play with me,” the tree asked the boy. “I’m no longer a kid. I wouldn’t play around the tree any more.” the boy replied. “I want toys. I need money to buy them.” “Sorry, I don’t have money. But you can pick all my apples and sell them. So, you will have money.” The boy picked all the apples on the tree and left happily. The boy never came back after he picked the apples.

One day, the boy returned and the tree was so excited, “Come and play with me,” the tree said. “I don’t have time to play. I have to work for my family. We need a house for shelter. Can you help?” “Sorry, I don’t have a house. But you can cut off my branches to build your house.” So the boy cut all the branches off the tree and left happily. The tree was glad to see him happy but the boy never came back since then. The tree was again lonely and sad.

One hot summer day, the boy returned and the tree was pleased. “Come and play with me!” the tree said. “I am sad and getting old. I want to go sailing to relax myself. Can you give me a boat?” “Use my trunk to build your boat. You can sail far away and be happy.” So the boy cut the tree trunk to make a boat. He went sailing and never showed up for a long time.

Finally, the boy returned after he left for so many years. “Sorry, my boy. But I don’t have anything for you any more. The only thing left is my dying root,” the tree said with tears.

“Good! Old tree root is the best place to lean on and rest. Come and sit down with me and rest.” The boy sat down and the tree was glad and smiled with tears.
