这句话的语法结构是怎样的,用到了哪些句型和语法?
From the standpiont of daily life,however,there is one thing we do know that man is here for the sake of other man——above all for those upon whose smile and well-being our own happiness depends,and also for the countless unknown souls with whose fate we are connected by a bond of sympathy.
这个长句如何理解?
我们可以悟出这样一个道理：我们为别人而活.看到至亲至爱欢笑和幸福,我们才能幸福,我们为他们而活.还有无数素未蒙面的人,怜悯之心将我们同他们的命运联系起来,我们也为他们而活）

Answer 1

改变下位置：however然而,From the standpiont of daily life从我们日常生活来看,there is one thing we do（do是强调信号,只起强调作用不用翻译出来） know 我们可以悟出这样一个道理that ( man is here for the sake of other man——above all for those upon whose smile and well-being our own happiness depends,and also for the countless unknown souls with whose fate we are connected by a bond of sympathy).
看到了吗 从that到最后 都是know的宾语 是由that构成的宾语从句 好 下面分析这个从句
man is here for the sake of other man人们为了别人而活——above all 尤其是 for those 为了那些upon whose smile and well-being our own happiness depends（upon whose smile and well-being our own happiness depends在这里又是个定语从句,修饰those,作those的定语）我们幸福的来源—我们至亲至爱欢笑和幸福,and 还有also for the countless unknown souls 无数不认识的人with whose fate we are connected by a bond of sympathy（with whose fate we are connected by a bond of sympathy又是个定语从句 修饰the countless unknown souls）怜悯之心将我们同他们的命运联系起来.
