you have been admitted to studies in Humanities at the faculty of arts and science.句中 to studies對嗎？

文法上是勉強可以的.study可以當名詞用.可以是"書房"或是"研究機構".又假如這些地方是有會員機制的話,這句話再加上<冠詞>就可以解釋得通的.

You have been admitted to THE studies in humanities FOR the faculty of A&S.

意思是:

你被接受為XXX的會員了!

studies在這句中可以看作是指"課堂"/"學術"的名詞，而不是動詞，不是一般普通文法句式，另外注意adimit(ted) to是一組詞(收取入學)，因此你讀英文句的技巧上仍要多理解不同的用詞和寫法。

其實這句簡化只是說：
You have been admitted to the Faculty of Arts and Science[可停在這裏]，附插加中間的表示這學系中的Humanities主修科的studies(可以上你是課堂了)。留意句中的各種preposition是你要學習的(要問便應該問為何不同)：
"in" Humanities 
"at" the Faculty of Arts and Science
[學懂了in, at, on, of, ...才不會寫錯配對]

順帶一提
大學的學術結構可以有多層的：
- 大學University
- 學院College 
- 學系Faculty(例如這句中的Arts and Science其實應該是要大寫頭的)
- 學科/專科Major(例如這句中的Humanities人文科學) 
- 課堂Course/Class
課堂中亦分為不同類形的教學類：教授講課lecture，導師輔課tutorial，實驗課Laboratory，研討課Discussion/Group Study，專題/設計/實務等Project課....

一般專上學府收生只會這樣說:  (留意介詞)
1. ... admitted to the [faculty name] at [college name]
2. ... admitted to the [program name] in the [faculty name] at [college name]
Please note that all those names must be in capital letters.
