  • 35、A million tourists go to Barcelona every year. They want to see Antonio Gaude's church. This unusual church has a strange history. Gaude was born in Spain in 1852. He had to work and study at the same time. He often missed classes because he had to work, but one day he designed a very unusual show-case for an exhibition in Paris. People began to give him work. He designed houses, offices and gardens. They were all very unusual. He was soon rich and famous. Then a rich bookseller said, "Will you build a church for the poor people of Barcelona? I will pay. I will build schools and workshops, too. They will help the people." "I will do it," said Gaudi. He worked for forty years, but he could not finish the church. It was too big. He needed $10,000,000. He gave all his money to the church. He was poor again when he died in 1926, and only the front of the church was finished. But architects, engineers and tourists from all over the world come to see it. It is very strange, very modern and very revolutionary.统考英语阅读理解
