96：大家都知道要在元音前用an，比如：an offer, an object等。但如果那个词只是听上去像个元音，例如缩写RCI前面，那用an是不是正确呢？

Everyone knows to use "an" before a vowel (i.e., an offer, an object, etc.). However, if the word sounds like a vowel, as in the acronym RCI (i.e., an RCI code), is "an" the correct usage.

Answer: It's the SOUND that counts, not the letter, so "an RCI ..." is correct. It works the same with vowel letters too -- a one-stop shop (o sounds like w) a unique opportunity (u sounds like y)

回答：起决定作用的是发音而不是字母，所以an RCI是正确的。对于元音字母也是这么判断的，例如：a one-stop shop (o 在这里是w的发音)；a unique opportunity (u在这里是y的发音)
