We drink tea every day. But more than three hundred years ago most of the people in Europe (欧洲) did not know anything about tea. Some people heard about it, but very few of them know what to do with it.

　There is a story about an English sailor (水手) who went to countries in the east, the west and the south. He went to India and China. One day he came home and brought some tea as a present for his mother. She told her friends about the present and asked them to a "tea party". When her friends came to the "tea party", the old woman gave them brown tea-leaves. The old woman's friends began to eat them. Of course, nobody liked the tea-leaves.

　At that time the sailor came in. He looked at the table and said, "Mother，what did you do with the tea?"

　"I boiled it，as you said."

　"And what did you do with the water?"

　"I threw it away(扔掉)，of course." answered the old woman.

　"Now you may throw away the leaves，too，" said her son.

Everyone began to make a cake. But Sophie hadn’t decided what kind of cake to make.

There was only half an hour left. Sophie had not even begun. So she began to panic (恐慌). Then she got an idea. She ran out and came to a cake shop. She gave fifty dollars to the shop keeper and said, “Please give me a chocolate cake.”

Then Sophie came back and put the chocolate cake on the table. But a little boy saw her do that.

When the judges (裁判员) were just about to taste Sophie’s cake, the little boy said to the judges, “Please don’t taste her cake. She didn’t make it and she bought it from a cake shop.”

Are two holidays not enough? Do you dream of three, or even four? 1.这不再是梦想! Last month, the State Council(国务院) encouraged primary and high schools to give students a spring or autumn break without changing the total number of student vacation days.

Students in China currently only have long holidays in two seasons —summer and winter. These holidays are usually 10 to 12 weeks in total.“If we had spring and autumn breaks, 2.I would have time to taste all four seasons instead of burying (埋) myself in my studies,”Gao Yiran, a 15-year-old boy told China Daily. Seasonal holidays during autumn and spring may be something new in China, but not in other countries.

In the US, students usually have three holidays. Summer holiday is the longest one, and runs from mid-June until early September. Summer camp is one of kids’ favorite places to go to, where they can make new friends and try some new activities. Winter holiday starts from mid-December and ends in early January. Most kids and their parents go to spend time together over the Christmas period. Spring break comes in mid- March and 3.it is usually a 10-day holiday.

Schools in Japan start in April, as most people think that spring is the perfect time for new things. For school children ,summer holiday lasts from July 20 to August 31. Most kids are busy with club activities including sports and dancing. Spring break starts at the end of March and continues till early April. It is a good chance for a short family trip around the city.
