Per comparare due cose che sono uguali, si usa la formula:
as + aggettivo quantitativo + (sostantivo) + as
L'aggettivo quantitativo da usare varia se il sostantivo oggetto della comparazione è numerabile o non numerabile.
Con i sostantivi numerabili si usa as many e as few. Il sostantivo può essere omesso se risulta chiaro dal contesto, come nell'ultima frase di esempio.
- They have as many children as we do.
- We have as many customers as they do.
- Tom has as few books as Jane.
- There are as few houses in his village as in mine.
- You know as many people as I do.
- I have visited the States as many times as he has.
- I have three brothers. That's as many as you have. ("brothers" è sottointeso)
Sostantivi non numerabili
Con i sostantivi non numerabili si usa as much o as little. Il sostantivo può essere omesso se risulta chiaro dal contesto, come nell'ultima frase di esempio.
- John eats as much food as Peter.
- Jim has as little patience as Sam.
- You've heard as much news as I have.
- He's had as much success as his brother has.
- They've got as little water as we have.
- I'm not hungry. I've had as much as I want. ("food" è sottointeso)
