科技推动了人类社会发展，改变了世界面貌。阅读下列材料回答问题。

    18世纪中叶以来，人类历史上先后发生了三次科技革命，发源于西方国家及衍生国家，并由他们所创新所主导。第一次科技革命（1760-1840年），标志着农耕文明向工业文明的过渡，改变社会关系和国际格局，推动了人类的发展进程；第二次科技革命进入了“XX时代”（19世纪70年代-20世纪初），使得电力、化工、汽车等重工业兴起，提炼出的新能源，用于新的交通工具，促使交通的迅速发展，世界各国的交流更为频繁；二战后开始的第三次科技革命还在全球扩散和传播。前三次科技革命使得人类发展进入了空前繁荣的时代，与此同时，也造成了巨大的能源、资源消耗，付出了巨大的环境污染、生态破坏的代价，急剧地扩大了人与自然之间的矛盾。———百度百科

   (One day Alice runs after a strange rabbit and comes into a deep hole. She becomes smaller when she wakes up the next day. She finds herself in a wonderland with many amazing things inside.)
   The Caterpillar(毛毛虫) and Alice looked at each other for some time in silence. At last the Caterpillar took the pipe out of its mouth, and said to her in a tired, sleepy voice.
   “Who are YOU?” said the Caterpillar.
   This opening for a talk couldn’t make Alice at ease. Alice replied, rather shyly, “I----I hardly know, sir, just at present ----at least I know who I was when I got up this morning, but I think I must have been changed several times since then.”
   “What do you mean by that?” said the Caterpillar, “Explain yourself!”
   “I can’t explain MYSELF. I’m afraid, sir.” said Alice, “because I’m not myself, you see.”
   “I don’t see.” said the Caterpillar.
   “I’m afraid I can’t put it more clearly.” Alice replied very politely, “for I can’t understand it myself. And being so many different sizes in a day is very puzzling.”
   “It isn’t.” said the Caterpillar.
   “Well, perhaps you haven’t found it so yet.” said Alice. “But when you have to turn into a chrysalis(蛹，茧)----you will some day, you know ----and then after that into a butterfly, I think you’ll feel it a little stranger, won’t you?”
   “Not a bit.” said the Caterpillar.
   “Well, perhaps your feelings may be different.” said Alice. “All I know is, it would make ME feel very strange.”
   “You!” said the Caterpillar scornfully. “Who are YOU?” The question brought them back again to the beginning of the talk. Alice felt a little angry because the Caterpillar was making such VERY short sentences. She drew herself up and said very seriously, “I think you ought to tell me who YOU are first.”
   “Why?” said the Caterpillar.
   Here was another puzzling question. As Alice could not think out any good reason, and as the Caterpillar seemed to be very unpleasant, she turned away.
   “Come back!” the Caterpillar called after her. “I’ve something important to tell you!”
   This certainly gave Alice some hope. Alice turned and came back again.
