i'm really confused!
Well, you have no trouble with "I am" and even its contraction.
to be usually is followed by an infinitive, an -ing verb.
hope that helps.
Lies lies and more lies, it depends on what you want to say, it can also be followed by the past participle form of a verb. Anyway, I'm still thinking about how to explain it.
Alright, I'll give it a try:
When to be is followed by a verb then it is meant to explain the situation of the noun:
Example 1: She is mowing the lawn
tells you what she does at this moment
Example 2: He was perplexed by the question
Tells you the situation of that guy in the past
Example 3: The tickets will be sold out by the time you get there
Tells you the situation of the tickets in the future
This verb is particularly complex as well as important, I'm still not sure what you mean by explaining it but I hope this has helped you.
ah! i understand now. thank you!
What, no Hamlet?
What's wrong with you people?
