Answer: In the first eight lines or the first two quatrains of the Sonnet Eighteen Shakespeare compares the beauty of his beloved to the summer and all the natural forces that surround this season like “Rough winds do shake the darling buds of May” and “Sometime too hot the eye of heaven shines”, however, in the last quatrain he declares the immortality of the beauty of his beloved in the lines he write, in this poem he/she will be immortal and not ever the death will own it “Nor shall Death brag thou wander'st in his shade” and in the couplet declares the longevity of that eternity “ So long as men can breathe or eyes can see,” and “So long lives this, and this gives life to thee.”
