Conjunction "as"

Hello :slight_smile:

Please tell me if the following sentences are correct? If they are, what’s the difference?

  1. A) As I walked along the street, I looked in the store windows.
    B) I walked along the street as I looked in the store windows.

  2. A) I watched her a she opened the letter.
    B) As I watched her, she opened the letter.

Thanks for the help:)

Assuming there’s a typo in 2A (a she opened), they are all correct. The difference is on the focus of the activity - the part of the sentence you wish to stress.
