The document discusses the third conditional, which is used to talk about impossible past situations. It provides examples of third conditional sentences using the structure "if + past perfect, would/could/might + have + past participle." It notes common errors in third conditional formation and shows how the clauses can be reversed. Additional examples are given using negatives and questions. Finally, it mentions that other modals besides "would" can be used and provides a link for exercises on third conditional sentences.
2. The third conditional
oWe use the third conditional for things that are
impossible.
o If Michael Jackson hadnt died he would have sung with Lady Gaga.
Past perfect would + have+PAST
PARTICIPLE
3. Three common errors:
1. he would has given
(have is an infinitive in
these sentences)
2. he would have gave
(participle, not past tense!)
3. if he would have given
(if never goes with would)
4. Guess what! We can also turn
this sentences around:
o If Michael Jackson hadnt died, he would have sung with Lady Gaga.
o Past perfect would + have+past
participle
o Michael Jackson would have sung with Lady Gaga if he hadnt died.
5. Other examples
oNegatives:
oIf he hadnt met Angelina, he wouldnt have left his wife
oIf she had liked Chicago, she wouldnt have moved to Seville.
oIf Kathy hadnt liked cycling, she would have picked aerobics.
oQuestions
oWhat would you have done if you had been in my situation?
oIf you had been in my situation, what would you have done?
(notice the IF clause is in AFFIRMATIVE)
6. VARIATIONS
oYou can use other modals instead of would:
oIf Julia had found Miguel at the party, he could
have driven her home in his car.
oShe might have visited Peter if he had been
in Berlin at that time.
