导游人员进行自我心理调节时，应明确的自己的三个定位是什么。

如图所示是一种自动控制水温的装置，加热电路的两端P、Q应接在触头a、b之间还是c、d之间？热敏电阻两端M、N应接在哪两个触头之间？

材料一 近来，随着手机生产牌照审批制的放开，以前的一些黑手机也由幕后走到了台前，这些手机的外形通常与一些知名品牌的热门产品相似，大多基于廉价的 MTK平台，外观新颖、功能全面、价格低廉，但做工粗犷、质量平平，没有正式的品牌，有些甚至是打着Scnyericcsun、NCKIA、SAMSING这样的擦边球，这些手机通常被冠以“山寨机”的头衔。深圳手机厂家2007年生产1.5亿部手机，产值近1000亿元，其中出口接近1亿部，深圳的手机牌照40张，占全国约一半。

材料二 山寨机的生产基本是分工协作，采取上下游订单形式协同作业，在深圳、东莞一带，有一条从手机配件、芯片、电池、刻模到组装的生产链，尽管彼此独立，但协作极为灵活。这种手机价格非常低，实际上是以逃避入网测试、认证检查等为代价，牺牲众多质量标准，因此质量水平根本无法保证。

     Why should I teach my children history? That sounds like a stupid question to even ask. But, as I hear

different home schooling teachers discuss history, I get the idea that there may be different reasons for

teaching history. Let me briefly explain the three good reasons for studying history and two bad reasons

for studying history.

     The major reason I see for studying history is that we can learn from the past. I am convinced that the

world would be a much better place if more people understood the successes and failures of the past and

the things that made these successes and failures. However, as the unfortunately true statement goes "the

one thing we seem to learn from history is that we don't seem to learn from history." Perhaps at least in

teaching history, to my children I can do a small part in changing this.

     A second major reason for studying history is that it is hard to understand the current political climate

in the absence of an understanding of its historical context. We can- not even understand why we are and

where we are without history, much less (更不必说) try to figure out where we are going or how we

should get where we want to be.

     I teach my children history, for one more reason. I purchased a set of historical audio (录音机) tapes

for our children. My seven-year-old son listened to them over and over. It was my hope that he would

become inspired by the accomplishments of people like the Wright brothers to accomplish things by

himself. I think that it is good that we celebrate the accomplishments of people like Martin Luther King Jr.

if, in doing so, young people are called on to stand for the principles that he stood for and accomplish what

he accomplished. I also think that by studying people like Adolph Hitler, people can learn to stand against

the things that he stood for.
