Sometimes, you know what you want to say, so it is hard to see what you've really said. Here are a few examples of confusing sentences:
Switching on the TV, the room seemed brighter.
After spilling the milk, the power went out.
Closing the windows and curtains, the storm continued to rage outside.
What's missing in all of these sentences? Yup! The actor. The person who did each of the actions is implied, but not stated. This makes each sentence a little bit confusing. By adding the person to each sentence, you can make the information much clearer.
So, how would you change my sample sentences?
