阅读下面短文,从短文后各题所给的A、B、C和D四个选项中,选出可以填入空白处的最佳选项。
For thousands of years, civilizations all over the world have used music to heal people. But it's only in the last few years that scientists 56 (begin) to discover why it works.
When we listen to music almost every part of the brain lights up-from the areas that control movement and memory 57 those that process language and emotion. It's like 58 (set) a firework off inside our heads. In the same way that bodybuilders grow big muscles from working out at the gym, the more we use a part of our brain, the 59 (strong) it becomes.
Modern music therapists use this knowledge to exercise 60 (damage) parts of the brain that are not 61 (access) in any other way. Listening to the rhythm of music turns on movement areas of the brain, 62 helps people with Parkinson's disease become more mobile. Singing 63 (activate) language areas 64 is used to help stroke victims learn to talk again. The emotional impact of music has even been used to help children with autism learn to understand other people's emotions, helping them with social interaction and self-expression skills. By listening to and performing music, people can 65 (true) rebuild the structures of their mind.

(3)工作一段时间后,当12.8 g甲醇完全反应生成CO2时,有 NA个电子转移。
【答案】(1)CH3OH O2 (2)CH3OH-6e-+H2O=CO2↑+6H+ (3)2.4
【解析】(1)根据氢离子移动方向知,右侧电极为正极,正极上氧气得电子,左侧电极为负极,负极上通入燃料甲醇。(2)负极上甲醇失电子和水反应生成二氧化碳和氢离子,电极反应式为CH3OH-6e-+H2O=CO2↑+6H+。(3)根据CH3OH-6e-+H2O=CO2↑+6H+知,当12.8 g甲醇完全反应生成CO2时,转移电子的物质的量为×6=2.4 mol,则转移电子个数为2.4 NA。
22.锂离子二次电池的负极材料为金属锂和石墨的复合材料(石墨作为金属锂的载体),电池反应为FePO4(s)+Li(s)LiFePO4(s),装置如图:
(1)该电池不能用电解质水溶液,原因是 。
(2)放电时,b 极的电极反应式是 。
【答案】(1)金属锂可与水发生反应(或2Li+2H2O=2LiOH+H2↑)


③XeFa(0+F(g)=XcF,(g)△H
