Answer Below :)
Step-by-step explanation:
For Number 5, what is being personified is the summers "eye" (also you can use complexion as personification). You should probably know this but personification puts human traits to non human traits. And what it reveals about summer is that summer is hot and also that that the sun is out for only some of the time. For 6, the speaker emphasizes (line 1) that if he can compare (the person he is talking to) to a summer day.
Hope this helps :)
