1 is right (should be 'listening TO the radio') 2 is almost right, it means the rooms were cleaned, but probably by someone else. the speaker paid someone or ordered someone to clean the rooms. 3 is right

#1. Your very close with this one. There are actually many different ways to say this phrase. - "As I was working, I had the radio on." This is a good sentence! But you can also re-order the sentence structure to this: - "I had the radio on while I was working." OR by substituting "As" with "While": - "While I was working, I had the radio on." The sentence, "I was working, listening the radio", doesn't make to much sense even though I know what your trying to say. Since you say I "WAS" working, this makes this sentence set in the PAST tense, that means the next part will also need to be set in the "PAST" tense. So it would look like this: -"I was working, listening the radio" CHANGES TO - > While I was working, I listened to the radio. "Listening" is future tense, that's why changing it to it's past tense form, "Listened", works much better! Another structure you can use is: - "I listened to the radio while I was working." I personally think this one sounds the most natural. = D #2. I had your rooms cleaned -> Good sentence! - "I cleaned you rooms" The only thing that needs changed in this sentence is that "you" needs to be changed to "your". "You" should be possessive since it's saying that people own those rooms. So it would look like: I cleaned your (guy's) rooms. Unless your trying to say you cleaned one person's room then it would be: I cleaned your room. #3 We had our money stolen - > Good Sentence! - Our money was stolen - > Great Sentence! This one sounds a little more natural to me, but that might just be personal preference. Hope this was clear and helped you! ~Lexy
