editor前面用a还是an

前面用an，例如：

1、I am now in such a bad situatiom" says Joel， "I hope I am still working as an editor."“我现在的处境真糟糕，”乔尔说，“我真希望我还在当编辑。”

2、I was also an editor for our campus newspaper in China.在中国上大学时，我还当过学报编辑。

3、She was an editor of her class newspaper last year.她是去年班级报纸的编辑。

用an，因为a用于辅音音素开头的单词前，an用于元音音素开头的单词前，editor读音是以/e/元音音素开头，所以用an
