I remember that when I was in my teens，I used to refuse to follow the many “dos” and “don’ts” of my parents．For example，when I planned to sleep with my pet dog，they immediately said，”   1 “because they thought it was dangerous．This was just an example of the things I thought my parents were    2  about.       

Today，however，I am the father of a boy aged 15，and I find that I too，am pressuring my son with a lot of    3   that are hard for him．

The   4   day，I noticed that my son was wearing giant pants that could    5  three teenagers. No one should wear them．I commanded him to take them off at once .Usually，he  6  me，but this time he put his foot down．”What’s wrong with giant pants?  7  classmates wear them. And I don’t think you have the right to ask me to remove them，  8 you are my father!” said he．I    9   realized that we are now living in a society with more freedom，and that my son’s strong will on wearing giant pants was just an  10 of the generation gap(代沟) between us．Therefore，I gave in and now he is still wearing giant pants．

It’s 10:00 pm. A man leaves a restaurant, gets into his car and drives away. 200 metres further he’s stopped by a police officer.
Officer: Good evening, sir. We’re testing drivers for drunk driving. Would you please blow（吹）into this machine?
Man:   I’m sorry, I can’t do that. If I blow into that machine, I will get out of air.
Officer: Please come along to the office and we can give you a blood test.
Man:   I can’t do that. If you give me a blood test, I will bleed（流血）to death.
Officer: Then you’ll have to get out and walk five metres along this white line.
Man:   I can’t do that, either.
Officer: Why not?
Man:   Because I’m dead drunk! I can’t open the door.

Cu的化合物在生活及科研中有重要作用，不同反应可制得不同状态的Cu₂O
（1）科学研究发现纳米级的Cu₂O可作为太阳光分解水的催化剂。
①在加热条件下用液态肼（N₂H₄）还原新制Cu（OH）₂可制备纳米级Cu₂O，同时放出N₂。当收集的N₂体积为3.36L（已换算为标准状况）时，可制备纳米级Cu₂O的质量为        ；

②一定温度下，在2 L密闭容器中加入纳米级Cu₂O并通入0.20 mol水蒸气，发生反应：
  ；测得20 min时O₂的物质的量为0.0016 mol，则前20 min的反应速率v（H₂O）=                  ；该温度下，反应的平衡常数表达式K=                  ；下图表示在t₁时刻达到平衡后，只改变一个条件又达到平衡的不同时段内，H₂的浓度随时间变化的情况，则t₁时平衡的移动方向为      ，t₂时改变的条件可能为              ；若以K₁、K₂、K₃分别表示t₁时刻起改变条件的三个时间段内的平衡常数，t₃时刻没有加入或减少体系中的任何物质，则K₁、K₂、K₃的关系为                ；
（2）已知：ΔH＝－293kJ·mol^－1           
ΔH＝－221kJ·mol^－1
请写出用足量炭粉还原CuO（s）制备Cu₂O（s）的热化学方程式        ；
（3）用电解法也可制备Cu₂O。原理如右上图所示，则阳极电极反应可以表示为        。
