Posted by The Verb Be
You can ask yes/no questions and wh- questions with the verb be.
A lot of Americans, in general, have problems with this – specifically possessive adjectives.
Example: Your happy.
You can’t use “your” because “your” is signaling possession. Your chair, your phone, your hammer, your book. Happy is an adjective.
Correct: You’re happy.
Here are some forms.
Yes/No questions Is yellow your favorite color? (Yes, it is. / No, it isn’t)
Am/Is/Are + subject Are you American? (Yes, I am / No, I’m not.)
Wh- questions Who is your favorite teacher? (Mr. Buck)
Wh- + am/is/are What are your interests? (Sports and movies)
- Complete these yes/no questions with Am, Is, or Are.
a. _____________ you from the states?
b. _____________ I your best friend?
c. _____________ yellow your favorite color?
d. _____________ our teacher Egyptian?
e. _____________ you from Estonia?
