  1. b) did it understandLa principale è invertita dopo not until, con did + soggetto + verbo base.
  2. c) thanNo sooner è seguito da than.
  3. b) shouldServe un modale per formare l'inversione con be left; should the door be left è corretto.
  4. a) wasSuch + be si inverte e concorda con il nome che segue. Noise è singolare, quindi was.
  5. c) did sheLittle apre la proposizione, quindi aggiungiamo did e torniamo alla forma base: did she realise.
  6. d) did the team publishOnly after + proposizione è seguito da una principale invertita: did the team publish.
  7. c) didIl passato di retreat richiede did, che corrisponde a had to be redrawn.
  8. c) whenHardly vuole when, mentre no sooner vuole than.

  1. had / hasNever before apre la proposizione, quindi l'ausiliare precede il soggetto: had the city faced (oppure has the city faced).
  2. did / wouldNot only è seguito da inversione nella propria proposizione: did the proposal cost.
  3. were / wasAt no time è un avverbiale negativo, quindi l'ausiliare del passivo va prima del soggetto. Staff normalmente è plurale nell'inglese britannico.
  4. must / should / may / can / shallOn no account richiede un modale prima del soggetto; must, should, may, can e shall vanno tutti bene.
  5. wereOnly when + proposizione è seguito da una principale invertita: were the explorers able.
  6. wasSo + aggettivo + be si inverte, e was concorda con the storm.
  7. did / wouldSeldom è un avverbio negativo, quindi l'ausiliare viene per primo: did she ask.
  8. thanNo sooner si completa sempre con than.
