近年来，城市内涝在我国一些大城市相继出现，下列有关城市内涝产生原因的叙述，正确的是（   ）
①城市地表硬化面积过大，不利于下渗 
②城市管网不完善，城市规划赶不上城市化发展
③地势低洼，排水不畅 
④城市化带来的“雨岛效应”,易导致降水强度增大

能源短缺是人类社会面临的重大问题．甲醇是一种可再生能源，具有广泛的开发和应用前景．

（1）工业上一般采用下列两种反应合成甲醇：

反应Ⅰ：CO（g）+2H₂（g）⇌CH₃OH（g）△H₁

反应Ⅱ：CO₂（g）+3H₂（g）⇌CH₃OH（g）+H₂O（g）△H₂

①上述反应符合“原子经济”原则的是____ （填“I”或“Ⅱ”）．

②下表所列数据是反应I在不同温度下的化学平衡常数（K）．

由表中数据判断△H₁____ 0 （填“＞”、“=”或“＜”）．

③某温度下，将2mol CO和6mol H₂充入2L的密闭容器中，充分反应，达到平衡后，测得c（CO）=0.2mol/L，则CO的转化率为____ ，此时的温度为____ （从上表中选择）．

（2）已知在常温常压下：

①2CH₃OH（l）+3O₂（g）=2CO₂（g）+4H₂O（g）△H=﹣1275.6kJ/mol

②2CO（g）+O₂（g）=2CO₂（g）△H=﹣566.0kJ/mol

③H₂O（g）=H₂O（l）△H=﹣44.0kJ/mol

写出甲醇不完全燃烧生成一氧化碳和液态水的热化学方程式：____ 

（3）某实验小组依据甲醇燃烧的反应原理，设计如图所示的电池装置．

①该电池正极的电极反应为____ ．

②工作一段时间后，测得溶液的pH减小，该电池总反应的化学方程式为____ 

   Many years ago there lived two brothers in London. They were both very rich. They had  1  ideas about money. They were quarrelling（争吵）about what would happen if a poor man could 2  a million pound note. One thought that anyone with such a note would have  3 he wanted; the other thought that it would be  4 for him to get anything with the note（钞票）.They couldn’t agree with each other. So they 5  to make a bet (打赌).
   It happened that a young man named Henry was wandering through the street that day, who had come to Britain only chance.  6 home and job, he looked pale（苍白的）and  7 . Suddenly he saw an apple  8  away by a child. The man was so hungry that he was thinking of picking it up to eat. Just as he was  9 out his hand, he heard a voice calling him. He looked up and saw the two  10. They gave him an envelope. They told him not to open it until two o’clock. They said, “Nothing but money in it.” Then they lef.
