I’ll remember the first carnival（狂欢节）. 小题1:. My parents came from Jamaica and they helped to start carnival. We had very little money, but we made costumers from old bits of material and feathers, and colourful masks. We decorated old lorries, so that we could ride on them through the streets. It took us six months to get ready.
But on the big day, all our hard work had been worth it. People of all ages, from babies to grandparents, black and white, danced together in the street. 小题2:. The music was played on anything made of metal: it was very noisy.
There were people watching from the windows of every house. We ate all our favourite Jamaican food, washed down with beer.小题3:– but carnival helps you forget the weather!
When the carnival got too big, those old streets became too narrow for such big crowds（人群）. Some people said they felt frightened by the large crowds and the noise. We were worried that carnival would be banned（禁止）. Then we found an answer – everything was moved to a wider and safer street. 小题4:.

A. It was in the 1960s B. The weather was wet C. The policemen danced, too D. But sometimes it’s too crazy E. So carnival should continue for years.
