EXERCISE 28-1 Using Commas
Add any necessary commas to the following sentences, and remove any commas that do not belong. Some sentences may be correct. Example:
He was so upset about his lack of connection to the outside world that he might as well have not even come on the trip.
When we returned to the hotel he couldn’t wait to check for any messages.
James logged on to the hotel wifi immediately but he was surprised to find that he hadn’t gotten any e-mails all morning.
His office hadn’t called him nor had his friends left him any messages.
He pretended to be relieved that nothing urgent had come up at work but I think he was secretly annoyed that everyone was doing fine without him.
