哪位大侠帮我分析一下下面这句话的语法啊?When times become difficult (and you kno

你这个句子不完整,我刚好回答了一个类似句子,以下是我给那个问题的回答,请参考When times become difficult (and you know they sometimes will),remember a moment in your life that was filled with joy and happiness。当日子变得艰难（你也知道有时会这样）,要回想起你生命中充满快乐和幸福的时刻。以上,When times become difficult 为when引导的时间状语,这个你应该很熟悉吧(and you know they sometimes will)是插入语,起补充说明作用,类似句子有He was （strange as it seems）an excellent sportsman。remember a moment in your life/ that was filled with joy and happiness。这句话是祈使句中带了定语从句。我用分隔符 “/” 给你标出了断句。你可以看到remember a moment in your life是简单的祈使句,in your life是后置定语,实际上a moment才是宾语,意为“要回想起你生命中的时刻"（在汉语中也可以发现“时刻”才是宾语）,那究竟是什么时刻呢?that was filled with joy and happiness这一长串就来修饰这个“时刻”了,是一个that引导的定语从句。本来没想到回复,但看到这个句子很好,挺积极向上的~想不到一下就打多了~再给你个相似句子自己试试分析?When life throws you one more obstacle than you think you can handle,remember something you achieved through perseverance and by struggling to the end。附那个问题的网址：
