《怦然心动》是一部深受喜爱的青春电影，以下是一些经典台词的英文完整内容：

A painting is more than the sum of its parts. A cow by itself is just a cow. A meadow by itself is just grass, flowers. And the sun peeking through the trees is just a beam of light. But a little discomfort in the beginning can save a whole lot of pain down the road.

一幅画不仅仅是它各部分的总和。一头牛单独看只是牛，一片草地单独看只是草和花，阳光透过树叶只是光束。但一开始的小不适可以避免一路的痛苦。

I never felt inferior because I lived where I did, nor did I think too much about being poor. I knew we weren't wealthy, but I never felt like I missed out on anything.

我从未因为住在哪里而感到自卑，也没有太多地想过贫穷。我知道我们不富裕，但我感觉我没有错过任何东西。

The higher I got, the more amazed I was by the view.

我爬得越高，越为眼前的风景所惊叹。

Some days the sunsets would be purple and pink. And some days they were a blazing orange setting fire to the sky.

有些日子日落是紫色和粉色的，有些日子则是燃烧般的橙色，点燃了天空。

Here I was, dying inside. All I ever wanted was for Juli Baker to leave me alone.

我在这里，心都要碎了。我所求的只是朱莉·贝克能离我远点。

Loyalty gave way to desire and Garrett, the turncoat.

忠诚让位于欲望，加勒特，那个叛徒。

Somehow the silence seemed to say, "I know." All I knew was that he was holding my hand and looking into my eyes deeply.

不知怎的，沉默似乎在说：“我知道。”我所知道的就是，他紧紧握住我的手，与我深情对视。

But every once in a while, you find someone who's iridescent, and when you do, nothing will ever compare.

但总会有一天，你会遇到一个人，你是如此绚烂夺目，当你遇到这个人后，其他人就不过是浮云而已。

这些台词不仅展现了电影中角色的情感和成长，也传递了许多深刻的人生哲理。希望这些台词能触动你的心弦。
