莎士比亚最好的一首诗是 《十四行诗第18首》，也被称为《Shall I compare thee to a summer's day？》。这首诗是一个非常浪漫的情诗，以表达诗人对他爱人的赞美之情。诗中写道：
```
Shall I compare thee to a summer's day？
Thou art more lovely and more temperate:
Rough winds do shake the darling buds of May,
And summer's lease hath all too short a date:
Sometime too hot the eye of heaven shines,
And often is his gold complexion dimmed；
And every fair from fair sometime declines,
By chance, or nature's changing course untrimmed；
But thy eternal summer shall not fade,
Nor shall death brag thou wanderest in his shade,
When in eternal lines to time thou grow'st:
So long as men can breathe or eyes can see,
So long lives this, and this gives life to thee.
```
这首诗以简洁明了的语言，将爱情与夏日进行比喻，表达了爱情的美好和短暂，以及时间的无情和不可逆转。这首诗的形式也非常经典，采用了十四行诗的形式，每行十个音节，遵循了英语诗歌的韵律和节奏。
此外，莎士比亚的其他著名诗作还包括《维纳斯与阿多尼》、《暴风雨》等，这些作品都展现了莎士比亚卓越的文学才华和对爱情的深刻洞察。
