You often find somebody who works around you complaining all the time, don’t you?  71   About 70% of Americans say being around nonstop complainers sometimes has a bad influence on them. Luckily, here are 4 tips to help form positive patterns.1. Self-awareness     When a negative thought pops into your mind, immediately correct it. Instead of telling yourself “That’s a nice shirt, but I can’t afford it,” change the message to “That will look great with my black pants when I can afford it.”   72  Of course, everyone complains sometimes. But the less frequently y小明家电热吹风机的铭牌如表格（甲）所示，其工作原理如图（乙）所示．由于使用了多年，吹风机中的电热丝明显氧化导致其电阻发生了变化，电动机性能仍保持不变．为准确测量氧化电热丝的实际电阻值，小明在家中把该吹风机单独接入家庭电路并使其吹热风，发现电能表的转盘6min内转过132圈，电能表规格如图（丙）所示．问：（1）氧化电热丝的实际电阻值是多少？（2）为恢复电热吹风机的铭牌功率，应与氧化电热丝串联还是并联一段新电热丝？（3）新电热丝的阻值是多少？
