整句為:get
excited
by
the
result.
意思是這個結果弄得我很激動。
其次，看妳這兒的選項，沒有by?
而of
可能是不太適合，因為沒有adj
+
of
+
the
N.的結構，除非
是固定搭配的adj.
經查相關字典，確實很難找到有at
\
about
\
for
這三個介詞的在此處的用法區別，但字典都有舉例，且在同壹詞條下。
以下是來自牛津高級學者字典的解釋(Oxford
Advaned
Learner‘s
Dictionary)

at
/

->

憑個人理解:+
at
...指具體的某個地方，某個時間，某件小事;+
about
...接人稱的比較多;+by...接結果事件類的比較多，當然+
to
do
sth.也是接的事件。
最後，推薦個人妳使用
by
.同時給妳壹個例句:It's
hard
not
to
get
excited
by
these
results
(意思為:這個結果令我高興，不高興都不行.
我也希望我的回答令妳高興。
