Our teacher takes us for a trip each term.During my first trip,we went to Couzy,Laon,Lille and Amiens.They are all in Northern France.Forty-one students went along with three of our teachers.The first place we went to was an old palace on the top of a mountain.It was very beautiful.The next place was the village of Laon.We visited a Notre Dame Cathedral there.
After we visited the two places,we then went to Lille,the fifth largest city in France.We walked around Lille and looked at different buildings.All were very interesting and each teacher told us what they think of each building.This became a more interesting way for us to learn architecture（建筑学）.The next day we traveled to Amiens to look at another Notre Dame Cathedral.Amiens is a n ice little town.As there was a famous university（大学）,we were able to see how other French students lived and studied.
The trip was great.且was tiring but.very helpful for us to understand architecture.
