Simple Present: Questions with Auxiliary Do/Does- Theory & Practice Exercise

The auxiliary Do/Does: Questions in the Simple Present Tense
With the exception of the verb to be, verbs in modern English use the auxiliary do to form questions and negative statements in the Simple Present.
The Simple Present of the verb to do is conjugated as follows:

I do

you do

he does

she does

it does

we do

they do

Auxiliaries are verbs which are combined with other verbs to form various tenses. It should be noted that when an auxiliary is combined with another verb, it is the auxiliary which must agree with the subject, while the form of the other verb remains invariable.

When the auxiliary do is combined with another verb, the other verb always has the form of the bare infinitive.

In order to form a question in the Simple Present of any verb other than the verb to be, the Simple Present of the auxiliary do is added before the subject, and the bare infinitive of the verb is placed after the subject. For example:

Affirmative Statement	Question
I work.	Do I work?
You work.	Do you work?
He works.	Does he work?
She works.	Does she work?
It works.	Does it work?
We work.	Do we work?
They work.	Do they work?

Change the following affirmative statements into questions. For example:
      She walks to work.
      Does she walk to work?

      They take the bus.
      Do they take the bus? Answers: 
1. Do I hurry home?
2. Does he drive a truck?
3. Do you follow the news?
4. Do they want a pet?
5. Does she like flowers?
6. Do we need tea?
7. Does she answer the questions?
8. Does he drink coffee?
9. Do I learn quickly?
10. Does it rain heavily?
