该句使用了when引导的时间状语从句，其中shed是shed的过去分词作后置定语修饰value，表达被动含义。
Today, while organizing my cabinet, I came across the weekly journals I kept with my homeroom teacher last semester. I couldn't resist opening them and reading from the first page to the last.
That semester, we talked about everything. You once said I was a girl who was 'too restless to be quiet.' You compared me to a time bomb that could explode anytime, which was why you had to pay extra attention to me. You remarked that my heart was truly elusive and that you couldn't quite get into it, wondering who really could. You encouraged me that since I had chosen this school, I needed to stick with it. You noted that I cried too often and asked me not to let tears fall easily, warning that Tears lose their value when shed too frequently. You also mentioned that it was a great luck to know me and our class. Finally, you told me not to miss you too much during the holidays.
That semester, you cared for me so deeply; you tried so hard to understand me; you encouraged me so much; and you cherished us so profoundly. I hope you never change and that you will still be with our class next semester. The reason is simple, and it's what you often said: spending time together always leads to genuine affection.
这一天，我在整理柜子时，翻到了上学期和班主任的周记。忍不住打开，从第一页一直看到最后一页。
那个学期，我们无话不谈。你也曾说我是一个“安静得无法安静”的女孩；你说过我就像一颗定时炸弹，随时可能在你身边爆发，所以你不得不多加关心我；你感叹说，我的心你真的捉摸不透，你真的走不进我的心，究竟谁能真正走进我的内心；你鼓励我说，既然选择了这所学校，就要坚持走下去；你曾指出我流泪太多，叮嘱我不要随意让眼泪落下，因为眼泪流多了就失去了价值；你还说，能认识我，能认识我们班，真的很幸运；最后，你曾叫我放假时不要太想你。
那个学期，那样关心我的你；那个学期，那样想了解我的你；那个学期，那样鼓励我的你；那时，那样珍惜我们的你！我期望你永远不变，期望下学期还能有你跟班。理由只有一个，那也是你常说的话：相处久了，总会有感情！
