Final answer:
Phrasal verbs combine a verb with an adverb or preposition, and sometimes both, to create a new meaning. Examples include 'get up' and 'stand by'. Phrasal verbs like 'look forward to' contain two prepositions and are idiomatic.
Step-by-step explanation:
The student is asked to identify and discuss phrasal verbs from given sentences. A phrasal verb is a verb that is made up of a main verb together with an adverb or a preposition, or sometimes both. For example, a verb with "get" might be "get up," which means to rise from bed after sleeping. A verb with "stand" could be "stand by," which means to support. Verbs with "hang" include "hang on" (to wait) or "hang up" (to end a phone call). Phrasal verbs with "over" could be "think over" (to consider) or "do over" (to redo). Lastly, "up" may form verbs such as "clean up" (to tidy) or "give up" (to surrender).
Some phrasal verbs contain two prepositions instead of one, such as "look forward to" or "put up with." These are often more idiomatic and can be trickier to understand. It is important to recognize the way each part of the phrasal verb, including multiple prepositions, contributes to its overall meaning.
