I only leave the notes when I am feeling in a ____ (happily) mood, as I don't want to pass any negative energy on to someone else.

下列诗句中反映一个人心境乐观开朗的是（    ）

智能洁具（智能马桶、全自动洗碗机、智能浴缸等），具有温水洗净、暖风烘干、杀菌等功能，已进入百姓家庭．

某智能洁具为确保安全，插头带漏电保护装置，工作原理如图甲，连接洁具的火线与零线穿过环形铁芯，正常工作时，两线中的电流相等；若火线与零线中的电流不等，绕在铁芯上的线圈会产生电流，经放大后通过电磁铁吸起铁质开关S切断电源．

这种洁具装有红外线感应装置，当人靠近时，感应装置自动升起洁具盖子；启动洗净功能，加热器将水快速加热至温控装置预设的温度，水泵喷水实施清洗，喷水杆采用纳米银（直径为纳米级的银单质）材料，杀菌效果好；清洗结束，暖风烘干机自动开启烘干功能．表一为该洁具的部分参数，表二为水泵的性能测试参数（表中流量指单位时间内水泵抽送水的体积；扬程指水泵能将水提升的高度）．
