Answer and Explanation:
Personification is a figure of speech in which human behaviors or traits are attributed to inanimate objects. Personification is commonly used in poetry or in texts that go for a more vivid description. An example of personification is: "The stars smiled at me." The stars do not have the ability to smile. They do not possess mouths. The author is most likely trying to convey the feeling of happiness by the use of personification.
With that in mind, let's explain the personification in each sentence.
1. The sun does not have eyes to glare at us. The personification here probably means that the sun was shining too brightly.
2. The trees do not have the ability to talk, much less to whisper. This probably means there was wind making the trees' branches and leaves move and produce a sound.
3. Birds cannot beckon since they have no hands. This is just a way of saying that their songs were so charming that the narrator and others felt like going outside to hear them.
4. The earth does not have the ability to be thirsty. It is not a person or an animal. The author most likely means that the earth was dry, in need of water, just like we are when we are thirsty.
5. Opportunity is not a human being with hands to be knocking on doors. This is a way of saying that we do not have opportunities often.
6. Night cannot snuggle since it does not have a body. This is a beautiful way of saying that it is growing dark outside.
7. Houses do not gaze. They do not have eyes. The narrator is most likely trying to convey a feeling of uneasiness concerning this house. Maybe it is haunted?
