Question

1. The boy was in danger.
2. The boy was dangerous.

(Are both the same?)

3. I have my friend's picture.
4. I have a picture of my friend.
5. I have a picture of my friend's.

(Are they the same? Does #3 mean #4? What about #5? What is the difference between the three sentences?)

Answer 1

1 and 2 are not the same.

1 means that the boy could be hurt.
2 means that the boy can hurt others.

3 and 4 are fine and mean the same thing. 5 is incorrect.
