this song is much to do with the book Alice in wonderland and it's sequel Through the looking glass, the latter I have yet to read, besides in here google is again out of order, so here please have my stingy contribution, a few guesses not worthing even one penny: And every creature lends themself to change your state of mind <----- 1 *lends themselves to: make themselves useful to. But now off with her head I fear is everyone's concern <------------- 2 *in Alice in wonderland there's a queen who always shouts 'off with his head' or 'off with her head' whenever and to whomever she feels like to punish, so this might be read as: I fear it's everyone's concern that the queen would want Alice's head still. She's unlocked the meaning for you <--------------------------------- 3 *unlock: reveal, illuminate.

first impression: 资讯 is most used by chinese speaker outside mainland china, like taiwan, hongkong, singapore, etc, it actually sounds more fancy. second thought: I also want to know about their diffrence.

never could step into the same river even if you wanted to :) everyday you are a little bit different, or so I hope... haha...

actually there isn't much of a difference between the three, they all express expectations of something is going to happen soon, ok, let's have some examples: 要下雨了 it's going to rain (immediacy actually implied here) 快要下雨了 it's going to rain soon 就要下雨了 it's going to rain soon maybe if you provide with more precise context...
