помогите пожалуйста по английскому правильно вставить глаголы в нужную форму???

Put the verbs in brackets into the correct form (active or passive)

Now gueuing is something that the English 1...(do) when they have to but we tend to think how to avoid the queue - usually find another place or later time. This time I 2...(save) by a young man who 3...(suggest) that if I wanted to change a few dollars we 4...(can) do it quicker outside in the street. I 5...(follow) him outside and gave him the two $50 notes. While I 6...(wait) for the money I 7...(tap) on the shoulder by another young man who 8...(explain) to me that it was a slightly dangerous practice to change money on the street. I 9...(embarrass) by this warning, and now 10...(want) to get out of this situation as soon as possible. I 11...(turn) to the chap and he returned the money immediately and went down the street. I stuffed the money in my pocket and 12...(go) in the other direction to find another place to change my cash. But when I 13...(take) the two notes out of my pocket I 14...(see) two one dollar notes! I might have saved ten minutes but I 15...(lose) nearly $100 instead and all because of my own stupid greed and impatience. I 16...(still wonder) where to seek help when I 17...(see) the two chaps who 18...(take) my dollars. I 19...(come) up to them and asked if they wanted me to explain the story to the militiaman who was a few metres away. The quickly handed me the two $50 notes - which this time I 20...(check) before pocketing them.
