爱是一种浪漫感觉的歌曲，歌词充满着对爱情的热情和渴望。以下是一首经典的英文歌曲《Yesterday》，它的旋律优美，歌词中表达了对过去美好时光的怀念和对未来充满希望的信念。

Yesterday, all my troubles seemed so far away

Now it looks as though they’re here to stay

Oh, I believe in yesterday

Suddenly, I’m not half the man I used to be

There’s a shadow hanging over me

Oh, yesterday came suddenly

Why she had to go, I don’t know, she wouldn’t say

I said something wrong, now I long for yesterday

Yesterday, love was such an easy game to play

Now I need a place to hide away

Oh, I believe in yesterday

Why she had to go, I don’t know, she wouldn’t say

I said something wrong, now I long for yesterday

Yesterday, love was such an easy game to play

Now I need a place to hide away

Oh, I believe in yesterday

虽然歌词中表达了对过去的怀念，但歌曲的主题却是对未来的希望和信念。它告诉我们，即使过去的美好不再，我们也应该充满希望，勇敢面对未来。就像歌词中所说的“Yesterday came suddenly, but today and tomorrow are always here”，我们不应该放弃对未来的希望，而是应该勇敢前行，创造更美好的明天。
