Both the simple past and the past participle forms of regular verbs end in -ed. When you speak, you might be in the habit of dropping this ending. In writing, however, you must use standard English verb forms. If you omit a final -ed when writing a simple past or past participle form of a regular verb, you make it hard for a reader to follow your thought.
Chapter 10 will help you to:
- recognize and use -ed endings in the simple past tense and in past participles.
- avoid incorrect uses of final -ed.
