Do

The verb "do" is kind of like the steering wheel of a car. It controls the direction of a sentence or a question. English teachers often refer to it as the helping verb or the auxiliary verb. When used with the main verb verb, "do" indicates whether a sentence is positive or negative, or if it's a question. Lesson One in the Red Level looks at "do" in the present tense.

Here are some examples:

Do you eat breakfast every morning? (question)

helping verb: do / main verb: eat

No, I don't eat breakfast every morning. (negative: do + not)

helping verb: do / main verb: eat �
