该句使用couldn't help but结构表示无法抑制的情感。
One day, while tidying my locker, I came across last semester's journals with my homeroom teacher, and I couldn't help but read from the first page to the last.
That semester, we talked about everything. You said I was a girl so quiet that it almost wasn't quiet, like a ticking time bomb that could go off at any moment near you. You said you couldn't help but care for me. You said my heart was truly hard to understand, and no one could really enter it. You said that since I chose this school, I should persist. You reminded me not to shed tears easily because too many tears lose their value. You said it was fortunate to know me and our class. You advised me not to miss you too much during the holidays.
That semester, you cared for me, wanted to understand me, encouraged me, and cherished us. I hope you never change and that next semester you'll still be our homeroom teacher. The reason is simple, as you often said, spending time together naturally builds feelings.
这天，收拾柜子的时候，我看到了上学期和班主任的周记，忍不住从第一页看到最后一页。
那学期，我们无话不谈。你说过我就是一个安静到不能安静的女孩，就像一颗定时炸弹，随时可能在你身边炸开。你说，如果不多关心我，你也无法放心。你说我的心难以捉摸，谁也无法真正走进我的心。你说，既然选择了这个学校，就要坚持走下去。你提醒我不要轻易落泪，因为泪水流多了就失去了价值。你说，能认识我和我们班，是件幸运的事。你叮嘱我放假的时候不要太想你。
那学期，你关心我，你想了解我，你鼓励我，你珍惜我们。我希望你永远不变，希望下学期还能有你跟班。理由很简单，就像你常说的，待久了，总会有感情。
