***** NOT A TEACHER *****
Hello, Andy:
I have noticed that many students are very confused regarding the correct form of the verb in questions.
Please remember that after any form of "do," you must use the so-called "base form" of the verb. The base form is the form of the verb that you look for in a dictionary.
For example, when you open a dictionary, you look for the word "eat" -- NOT "eats" or "ate" or "eating."
Another word for the base form is -- as a teacher reminded us -- the "bare infinitive" (the infinitive with NO "to").
I have made up a few examples for you to study:
Does Agile live in an apartment?
Did Agile drink coffee yesterday?
Does Agile like broccoli?
Did Agile go to school yesterday?
Agile does not have a computer.
Agile did not drive yesterday.
