阅读短文，回答下列问题：

干簧管（也叫干簧继电器）比一般机械开关结构简单、体积小、速度高、工作寿命长；而与电子开关相比，它又有抗负载冲击能力强的特点，工作可靠性很高．如图1所示为干簧管的结构简图，其中磁簧片是一种有弹性的薄铁片，被固定于玻璃管上．

（1）当将一个条形磁铁与干簧管平行放置时，如图2所示，干簧管的磁簧片触点就会闭合，将电路接通；当条形磁铁远离干簧管时，触点就会断开．请简述其原理．当将一个条形磁铁与干簧管平行放置时，干簧管的磁簧片就会被磁化，干簧管中相互靠近的两个触点被　闭合　成异名磁极而相互靠近，触点将会闭合，将电路接通；当条形磁铁远离干簧管时，磁簧片的　磁性　消失，在弹力的作用下触点断开．

（2）小阳想用干簧管制作一个水位自动报警器，除干簧管外，还有实验器材：开关、红灯、绿灯和电源各一个，导线若干，如图3是小阳设计的一部分电路，请帮助小阳在图3中的虚线方框内画出报警电路其余部分的电路设计，要求：水位到达A处时，红灯亮，电铃报警；水位到达B处时，绿灯亮，电铃报警．

根据短文理解，从A、B、C、D四个选项中选择正确答案填空。

    “Who would you like to change your life with if possible?” Last week, we asked many middle school students this question. The following are some of their 1.
