When this happens to young people, they too often try to grasp the love and hold it to them, refusing to see that it is a gift freely given and a gift that just as freely moves away.

【翻译】当这种情况发生在年轻人身上时，他们往往会努力抓住这份爱并坚守于它，不愿看到这是一份随意馈送的礼物，一份同样随意离开的礼物。

先分析第1句：

1. 总体看，refusing to see that it is a gift freely given and a gift that just as freely moves away.

是现在分词短语，作结果状语。说明“抓住这份爱并坚守”的结果。

2. that it is a gift freely given，是see的宾语从句，其中freely given是过去分词短语作定语。

3. and a gift that just as freely moves away，是and连接的与前文a gift freely given的并列成分。

4. that just as freely moves away是定语从句，修饰a gift，that 是关系代词，作从句的主语。在这个定语从句中，省略了与前文重复的比较从句。补充完整为：

a gift that moves away just as freely as it is given.

1. When this happens to young people, they too often try to grasp the love and hold it to them, refusing to see that it is a gift freely given and a gift that just as freely moves away.
