Nella rubrica Classic Books di questo mese parliamo di Disgrace, il romanzo del Premio Nobel J.M. Coetzee. Nel testo troviamo l’espressione It must be a losing battle. (Deve essere una battaglia persa), in cui must non sta a indicare un obbligo, ma è usato per esprimere una deduzione logica. Nella forma negativa non si usa mustn’t, ma can’t, come nell’esempio: You can’t be hungry again: you have just eaten two slices of pizza. (Non puoi avere di nuovo fame: hai appena mangiato due fette di pizza).

Completa le frasi con must oppure can’t.
