Forme verbali:
il periodo ipotetico
Il periodo ipotetico è composto da una frase principale e da una frase subordinata if, che esprime la
condizione necessaria affinché ciò che è detto nella principale si verifichi o meno. Il periodo ipotetico si
classifica in base al grado maggiore o minore di probabilità.
Zero conditional
Frase subordinata
Frase principale
If + Present simple
Present simple
If the water reaches 100 degrees C, it boils.
• Si usa il periodo ipotetico di tipo zero per esprimere la conseguenza logica
e naturale di una determinata azione: nell’esempio precedente, siamo certi
che se porto l’acqua a 100°C inizia a bollire.
First conditional
Frase subordinata
Frase principale
If + Present simple
will / won’t + verbo alla forma base
If I leave late,
I’ll (will) miss the train.
If you eat so much,
you won’t lose weight.
• Si usa il periodo ipotetico di primo tipo per parlare di un’azione possibile
o probabile nel presente o nel futuro.
Second conditional
Frase subordinata
Frase principale
If + Past simple
would / wouldn’t + verbo alla forma base
If he knew Chinese,
he’d (would) live in China.
If it didn’t rain,
I’d (would) go to the park.
• Il periodo ipotetico di secondo tipo esprime ipotesi poco probabili,
immaginarie o difficilmente realizzabili.
• Osserva questa costruzione particolare che prevede l’uso del periodo ipotetico del secondo tipo: si usa la
costruzione If I were you / him ecc. per dare consigli e suggerimenti.
Frase subordinata
Frase principale
If I were + pronome complemento oggetto
I would / wouldn’t + verbo alla forma base
If I were you,
I wouldn’t go out with such a bad weather.
If I were him,
I’d (would) tell his mother the truth.

Regole generali valide per tutti i periodi ipotetici
• La frase principale può essere all’inizio del periodo ipotetico:
We’ll go swimming if Dad drives us.
Andremo in piscina se papà ci porta in macchina.
• Quando il periodo ipotetico inizia con la frase introdotta da if, va inserita una virgola prima della frase
principale:
If I study harder, I’ll pass the exam. U I’ll pass the exam if I study harder.
Se studio di più, passerò l’esame.
Passerò l’esame se studio di più.
• Nelle domande, solo la frase principale va alla forma interrogativa:
Would you go to the concert if you found the tickets?
Andresti al concerto se trovassi i biglietti?
What will you do if you don’t pass the exams?
Cosa farai se non passi l’esame?
Watch out!
Nel periodo ipotetico si possono usare altre congiunzioni oltre a if:
I’ll give you a ring when I leave home.
Ti telefono quando esco da casa.
As soon as Harry moves to England, he’ll rent his house.
Appena Harry si trasferisce in Inghilterra affitterà la sua casa.
