   e. g. “why?” the teacher asked him.
         “both, sir.” he answered proudly.
6. to balance the sentence structure or to link the sentence closely.

t: in the following cases, part of the predicate comes before the subject.
    look at the screen.
    (show the following on the screen.)
1. to avoid repetition, “so, neither nor” can be placed at the beginning of a sentence which says that people (or thing or situation)are the same as others that have just been mentioned.
    e. g. (1)--my mother is ill this week.
          --so is my sister.
          (2)--i can't speak french.
          --nor can i.
          (3)--my husband never touches a drying-up cloth.
          --neither does mine.
    note: “so” can also be used in a different sense, to introduce surprised agreement with what has been said, which means “ yes, indeed! you're quite right. ”in this case, the same subject is mentioned. inversion is not used.
    e. g. --that's isabel, look!
           --so it is.
2. in sentences beginning with negative expressions like never, seldom hardly, scarcely, barely, rarely, little, not, nowhere ,by no means, in no way, at!
    no time, neither… (nor).
    e. g. hardly do i think it possible.
           by no means shall we give up.
           neither will theory do without practice; nor will practice do without theory.
    note: when “little” which does press negative is used as an adjective before the subject, natural word-order is used.
  e. g. little franz often played truant.
3. in sentence structures like “not only…, but (also) …; no sooner…than…;  hardly/scarcely…when…; not until…;so…that…; such…that…”.
  e. g. not only did we lose all our money, but we also came close to losing ourlives.
