Question

give me some rules of preposition

Answer 1

The preposition like means "similar to" or "similarly to." It should be followed by an object of the preposition (noun, pronoun, noun phrase), not by a subject and verb. Rule of thumb: Avoid like when a verb is involved. That is, you look similar to her.

Answer 2

A preposition is a word or set of words that indicates location (in, near, beside, on top of) or some other relationship between a noun or pronoun and other parts of the sentence (about, after, besides, instead of, in accordance with). A preposition isn't a preposition unless it goes with a related noun or pronoun, called the object of the preposition.
