She received a letter from her uncle who was a farmer in another part of the country.“Dear Mary,” the letter said. “Happy Birthday. I am sending you some chickens. They will arrive tomorrow. I hope you like them. Best wishes. Uncle Toby.”Mary was very pleased. She liked eating eggs so much and she liked eating chicken as well. “I can keep the chickens for eggs or eat them,” she thought.When the chickens arrived the next day, they were in a big box. Mary was very excited. She took the box off the back of the truck and began to carry it into her garden. However, the box of the chickens was heavy and she dropped it.The box fell to the ground and broke open. The chickens all ran out suddenly. They ran everywhere, into the neighbor’s gardens, into the road, into shops, even into the next street. Mary spent hours trying to find them and taking them back to her garden.A few days later her uncle came to see her.“Did the chickens arrive safely?” he asked Mary.“Yes, Uncle Toby,” Mary said. “But I had a lot of trouble with them. I dropped the box. It broke open and the chickens ran everywhere.

In different countries people have very different ideas about drinking tea.In China, for example, tea is always served when people get together. The Chinese drink it at any time of the day at homes or in teahouses. They prefer their tea plain(简单的,明白的), with nothing else in it.Tea is also important in Japan. The Japanese have a special way of serving tea called a tea ceremony (仪式). It is very old and full of meaning. In the ceremony everything must be done in a special way. There is even a special room for it in Japanese homes.Another tea drinking country is England. In England, the late afternoon is “teatime”. Almost everyone has a cup of tea then. The English usually make tea in a teapot and drink it with cream and sugar. They also eat cakes, cookies and little sandwiches at teatime.In the United States, people like to drink tea mostly for breakfast or after meals. Americans usually use tea bags to make their tea. The tea bags are faster and easier than making tea in teapots. In summer, many Americans drink cold tea, called “iced tea”. Sometimes they drink iced tea from cans, like soda(苏打汽水).根据短文内容选择最佳答案( ) 66. The passage is about ____________.A.
