TIP#6: Add "ed" to verbs for the Past Tense

When we talk about the past, we have to add an "-ed" to regular verbs to make the second form. Irregular verbs are tricky and have their own sets of rules. Drink, for example, turns to "drank." Most of the time, though, "-ed" will do.

For example:

• I drank a lot of Lapsang Souchong tea yesterday, but Mary didn't.

• The dogs stopped barking two seconds ago, and I am feeling better.

• Mary played fetch with her hyperactive dog.
