给出一首莎士比亚 Sonnet 的注释。


Sonnet 18: “Shall I compare thee to a summer’s day?”
本 Sonnet 主题为诗人对爱人之感情，诗人通过比较夏天与爱人之美貌，认为爱人之美丽胜过夏天，夏天凋零，而爱人之美将永存于诗中。 

Shall I compare thee to a summer's day?
Shall I liken you with a summer day?
Thou art more lovely and more temperate:
You are more lovely and more moderate:
Rough winds do shake the darling buds of May,
Rough winds disturb the beloved buds of May,
And summer's lease hath all too short a date:
And summer is far too short:
Sometime too hot the eye of heaven shines,
Sometimes the sun is too hot,
And often is his gold complexion dimm'd;
And often his golden face is dimmed;
And every fair from fair sometime declines,
And everything beautiful will someday age by Chance,
By chance, or nature's changing course untrimm'd;
Either by chance or by the unchanging laws of time;
But thy eternal summer shall not fade
But your eternal summer will not fade
Nor lose possession of that fair thou owest;
Nor lose the beauty you possess;
Nor shall Death brag thou wander'st in his shade,
Nor will death claim you for its own, 
When in eternal lines to time thou growest:
Because in my eternal verses you will live forever!
    So long as men can breathe or eyes can see,
As long as humans breathe and eyes can see,
    So long lives this and this gives life to thee.
So long will this poem live on and give you eternal life.
