Exercise 3:
just add 'ed': played
take off the 'e' + 'ed' double the last letter: stopped
Explanation:
When we form regular verbs in Past Simple, we normally add the termination 'ed' to their infinitive form.
e.g. played, lived, baked, pushed, etc.
However, there are some cases when we must apply some changes to the base of the verb, in order to obtain an adequate past simple form. If a verb ends in a vowel and a consonant, we double the consonant before adding -ed.
e.g. clapped, stopped, planned, etc.
