First notebook entry: Introducing myself

Because I do like to speak English, especially when I need it as much as air! 

"Because/'Cause" never generally opens a sentence.  If you wanted to use "cause" in this context, you could put an apostrophe in front (so it becomes 'cause) to indicate a slang abbreviation.

If you are comparing something using "as" (that is called a simile), it should be structured "as ____ as ____" 

That person is as tall as a tree!

This bread is as hard as a rock!

I hope this is helpful :)
