"A" or "AN"?? Help me, Orange!

Hi! I'm an orange. A very annoying orange... but in this opportunity, I will help you to learn the use of "A" or "AN" before a word.

You must say "A" when the following word starts with a consonant

By the otrer way, you must use "AN" when the follwing word starts with a vowel

I know... It's BOOOOORIINGG! jajajajajajaja

Let me show a example and some exercises:

This is my best friend, even if he's a boring guy:

He's Pear... and yes, he is A pear.



With this, you must be ready for practice with my friends:

__ apple and __ knife

__ midget apple

__ marshmallow

__ avocado

__ onion. He's called "Captain Obvius"... He's __ annoying guy!

He is __ egg.             And that is __ box of eggs

And finally... this is __ iPhone. It's mine! But it's boring because their creator was __ apple :P

Well... it's all by today, kids. See you laters, you apples!

Ah... and here's the reason of everything about apples. Take it like a bonus track =)
