更新1: i want to ask this question because i saw a sentence with the following structure in a newspaper ........apolozise both to him and to his family ..... When you repeat the preposition (or article) in a parallel construct you put an emphasis on each of the elements. So in the sentence: "... apologize both to him and to his family " the author stresses that the subject apologizes to o parties to make the apology more emphatic. If the author chooses to write "... apologize to both him and his family " the overall meaning is the same but the sentence serves to document an event. The last part of both of your sentences "in there " is incorrect. The proper preposition is "at" (at a university) but since you are using the word "there" which is an adverb you should drop the preposition. For example: "He is at the bus stop. He is there. (Not: He is at there)" And since you have already used the possessive adjective "its" in your sentence there is no need to include "there" because its purpose has already been iframeded into "its." Using "recognize" as the main verb seems inappropriate. Since the students and professors are already at Oxford why would they "recognize" Oxford as the best university? Normally recognition es from external or independent individuals or anizations. I would suggest that you switch the verb to "praise tout." Both sentences are correct in grammar. I would choose the first one because of the rhythm of the sentence since we have "in there" at the end of the sentence. The first sentence stresses in the word "both" which is a good break and balance of the first and second part of the sentence. The reader will pay attention to the word "both" which is the key of the sentence. The second sentence stresses at the end "in" there which is emphasizing the phrase "in there". The reader will pay attention to the phrase "in there" which is not the key of the sentence. 参考: Myself The 2nd one is correct.
