VENICE，a small，waterside city in northeast Italy，boils with happiness and excitement once every year.Between February 21 and March 4，carnival(狂欢节) hits the streets.

For most people，carnival means large parties and feasting(盛宴).But in Venice，it also means traditional masks and clothes.

These costumes were first meant to hide personal identities.Then，different social classes could mix in a sea of happiness.

Along the waterways，people greeted each other with “Good morning Ms. Mask！”

Today，people in Venice still dress up in the strangest ways—as armed soldiers，butchers and fishermen，for example.

Bars and cafes are filled with party­goers who come to show off their beautiful clothes.Their designs and creations are made by special studios.Ready­made costumes are not acceptable.

“In the months before the carnival we work overtime to meet the demand，”said a mask­maker.“Many kilometres of silk and lace(花边) are made into costumes.For shopkeepers，carnival is the best time of year.”

The Venice carnival dates back to the Middle Ages.At that time，the city was one of the wealthiest in Europe.

The tradition of celebrating with masks and costumes is thought to have been started by the “Stocking Companies”.These were groups of young men who organized parties and festivals and wore colourful stockings to distinguish(区分) themselves.

By the 18th century，the carnival had reached its top.It all came to an end when Napoleon controlled Venice in 1797.But in 1979，local people brought the old traditions back to life.

Now the Venice carnival attracts huge crowds from all over the world.This year，about 700,000 people are taking part in.Hotels were fully booked months in advance，and bars and restaurants overflow every day.

The city certainly benefits—a whole industry has been built up around the carnival’s masks and clothes.

“The Venice carnival is a magical time！It’s such a great experience，” said one French tourist.
