English Questions

Simple. Without going any complex into the sciences of English,

Usually this is how I roll:
1.
I like this means You are definite about what you prefer.
I do like this means in principle or perhaps, you prefer this.

2.
Usually.
How do you do, to me means how are you faring for health, life and work so forth.
How are you, to me means what are you on and about today. what have you been doing lately?

In speech, I do pop hellos in ways of "How's it going?", "What's happening?", "What's up?", "How you doin?", "How're things?"

Just a tip. Not science. :)
