It was my first time visiting the United States. Before (leave) for Washington D.C., I downloaded some introductions about some tourist (attract) in the city. Therefore, I knew something about this city before the trip. A lot of things happened during my trip to Washington D.C. However, what impressed me most was the International Spy Museum, I visited on the (three) day of the trip.

    In my spare time, I often watched movies about spies with my parents because I was (extreme) interested in spies. I acquired good knowledge of that after I read the descriptions in the museum. I learned that spies usually (hide) important letters in an umbrella, in a shoe, or even in a pair of ordinary glasses. When they thought they were probably found out, they could have their appearances (change) in a few minutes. They put on fake hair, eyes or teeth. If they had an emergency, in order not to (recognize), they even changed a smaller pair of shoes to change their walking styles. conclusion, it was a nice trip. I had a good time in Washington D.C. and I will remember it forever.
