     There are over 800 boarding (寄宿) schools in the United Kingdom with students from home and

foreign countries. Boarding schools started hundreds of years ago in the country. But the earliest boarding

schools were set up for white, rich boys only. Now, both boys and girls can go to boarding schools from

the age of 7 to 18.

     What to do

      In the United Kingdom, boarding schools have three terms in a school year, and there are about 13

weeks each term. Students study and live with one another. They need permission to go outside. In some

schools, each student has his or her own schedule. Besides the usual classrooms and laboratories, the

boarding schools have lots of other equipment for their students, including music rooms, boats, swimming

pools, cinemas and theaters. Most boarding schools have a"lights out" time. So when it's time to go to bed,

all the lights in the dormitories are turned off. Some senior teaching staff work as housemasters (舍监).

Each of them takes care of 50 students all the time, and especially after school hours.

     Nearly all students at boarding schools in the United Kingdom wear a school uniform. Boys usually wear

a shirt and a tie, and girls wear a white blouse (罩衫), sometimes also a tie and a skirt. As students get older,

the rules become less strict.

     What to eat

     In the United Kingdom, boarding schools provide students with delicious food. They can choose to have

a full English breakfast or simply bread with marmalade (柑橘酱). They can also choose between a vegetarian

meal and another meal at lunch and dinner. And there is always a salad buffet (自助餐), other side-dishes and

a dessert. Many boarding dormitories also have a kitchen so students can make themselves something to eat

at any time, or drink tea or have a snack between meals.
