Saving the earth（The Fifth Period）

   e. g. may you succeed!
         may you gain still greater success!
         cost what it may, i'll stick it out.
note: in “long live the people!”, inversion is used with the whole verb fore

t: now, let's look at the screen, there's another kind of inversion you should
  remember.
    (show the following on the screen.)
in an adverbial clause introduced by“as” or “though”.
structure:
predicative
adverbial      +as(though) +subject +…
verb      
e. g. much as i like it, 1 will not buy it.
      try as she might, she failed.
      child as he was, he had to make a living.
note: (1)when the adverbial clause is introduced by “though”, inverted and natural word-order are both possible.
e. g. though she is young, she knows a lot.
      young though she is, she knows a lot.
     (2)when the predicative is a countable noun in singular, “a” or “an” should be  left out.
e. g. hero as he is, he has some shortcomings.
