"您好,我是否能知道原因呢" translate to "Hello, can I know the reason" I translate &quot;您好,我是否能知道原因呢&quot; to &quot;Hello, can I know the reason&quot;
But it looks like lose courtesy meaning.
How to normally behavior courtesy meaning this chinese sentence in english?
The word 您 as an alternate for 你, implicates that you really respect the person you are talking, thus, you would also need to use 'May I' to show politeness while asking.
I would translate it as follow:
Greetings Sir/Madam, may I know what is the reason?
