Theory:

Phrasal verbs are phrases that indicate actions.
Phrasal verbs consist of a main verb plus either an adverb or a preposition. Phrasal verbs provide the action in a sentence. However, by combining a verb with an adverb or a preposition, the combination of words makes the verb phrase take the meaning of its own.
Example:
1. look for search/seek 
Sentence: He is looking for his keys.

2. look up to have a great deal of respect for a person 
Sentence: His father is his model. He is the person he looks up to.

3. look forward to await eagerly/anticipate with pleasure 
Sentence: She is looking forward to visiting Paris.
