Przykłady
W kontekście: Zmiana nawyków
Last year I decided to change my lifestyle.
I gave up eating sweets and started going to the gym.
At first I kept finding excuses, and I often forgot to pack my gym bag.
A friend advised me to train in the morning, before starting work.
Now I really enjoy exercising and I hope to run a half-marathon. I don't regret changing anything.
Typowe błędy
enjoy + -ing.
want + osoba + to. Nigdy „want that”.
Tu „to” jest przyimkiem → -ing.
suggest + -ing.
