You need to study up on phrasal verbs, particularly in regard to how they go in for idiomatic usage:
[QUOTE=Wikipedia]
It is, however, the figurative or idiomatic application in everyday speech which makes phrasal verbs so important:
* "I hope you will get over your operation quickly."
* "Work hard, and get your examination over WITH."
The literal meaning of “to get over”, in the sense of “to climb over something to get to the other side”, no longer applies to explain the subject’s enduring an operation or the stress of an examination which they have to overcome. It is when the combined meaning of verb plus adverb, or verb plus preposition is totally different from each its component parts, that the semantic content of the phrasal verb cannot be predicted by its constituent parts and so becomes much more difficult for a student learning English to recognise.
Other idiomatic usages of phrasal verbs show a verb + direct object + preposition/adverb + indirect object construction:
In her introduction to “Longman Dictionary of Phrasal Verbs, What this dictionary contains”, Rosemary Courtney includes as a third category
3. Idioms which are formed from phrasal verbs, such as let the cat out of the bag. These idioms are printed in heavy type. Idioms have a meaning which is different from the meaning of the single words, and usually have a fixed word order.[3]
Courtney then cites among many other examples in the dictionary such phrases as “to add insult to injury”, “to add fuel to the flames”, “to leave someone in the lurch”, “to scare someone out of their wits”, etc.
“To get over an examination” is not the correct application of the phrasal verb “to get over.” The author wants to imply, “to finish,” the phrasal verb in this case is “to get over with.” To get over the examination means put it in your emotional past.
