How to judge the usage of metaphor in sentences?

To judge the part-of-speech usage of a word in a sentence, we need to consider the context and combine the part-of-speech and usage of the word itself. The word "photo" means "photo" as a noun and "photo" as a verb.

The following is an example that explains the part of speech and usage of "photo":

I took a photo of the sunset. )

In this sentence, "photo" is a noun, which means photo. The "take" in the sentence is a verb, indicating the past tense of action. "Sunset" is a prepositional phrase, which modifies the previous "photo" and indicates the content of the photo.

Here is another example and explains the part of speech and usage of "photo":

I will shoot the scenery tomorrow. )

In this sentence, "photograph" is a verb, which means taking pictures. "Landscape" is a noun phrase, which means the object being photographed. "will" is a modal verb, indicating the action that will happen.
