Identify each sentence with declarative, interrogative, imperative or exclamatory and add punctuation.

1. Be thankful that George Eastman invented the film for your camera.

Answer: declarative

2. How easy is it to take pictures today?

Answer: interrogative and I added a question mark.

Did you read the information in the link I gave you earlier?

Yes!

Hmmm! One of your answers is wrong.

I believe 1 is correct. Is sentence 2 be imperative?

What is the subject of 1?

George Eastman

I'm confused!! Which one is right?

I see your problem. George Eastman is the subject of the dependent clause.

The independent clause is
"Be thankful."

What is the subject of "be?"

There is no subject?

And when there is no stated subject ... .
