Have you ever wondered what an American high school is really like? This article will describe a typical (典型的) high school and its students.

A typical American high school has several large buildings and enough space for about 1,500 students. Every student is given a locker. When students first arrive at school, they go straight to their lockers to put away or get their textbooks and to hang up their outdoor clothes. As American textbooks are expensive, students would rather borrow than buy them. Students must pay back if they lose any of them.

American students have different types of school transport. They usually take a yellow school bus or walk to school if they live close enough. Sometimes their parents drive them to school. When they turn 16 years of age, most take a free driving class at school for one term. If students get passing grades in the class and also pass their state driver’s exam, they can begin driving themselves to school.

Each day, students take six or seven classes. They must take science, maths, English and social studies. They can choose art, homemaking, clothes making and other classes. In some schools students are asked to take one or more of the following special classes: health education, physical education or foreign language studies. Students move to different classrooms for each subject. This is because each teacher has their own classroom. There is a five-minute break between classes, to give the students the time to hurry to their next class.

The school day usually ends early in the afternoon. After school more than half of the students take part in after-school activities. These activities include sports --- especially football, basketball, baseball and soccer or clubs, such as yearbook, speech, school newspaper, and photography and student government.

张小兰一家原来租住在李一伦所有的一套房屋内，租赁合同由丈夫王某与李一伦签订，后来王某不幸死亡。张小兰经同事介绍，与陈某再婚，并随夫搬至陈某处居住。为此，原告李一伦起诉要求被告张小兰及其女儿张亦兰二人腾退承租的住房两间。但被告二人辩称：被告张小兰虽然再婚随夫居住，因其女被告张亦兰一人仍住在承租原告的两间住房里，每星期回来两次与女儿同住。故不同意原告的诉讼请求。据此，人民法院主持双方当事人调解希望原、被告之间平息纠纷，和睦相处，但未能成功。假如本案在开庭审理时，被告张小兰、张亦兰向人民法院申请通知出庭作证的证人孙某没有到庭，经电话联系，孙某表示不想得罪人，不愿意出庭作证了。则产生以下何种法律后果：

B．再次通知孙某，如果孙某再不到庭，则可以拘传

C．孙某的证言将不能作为单独认定案件事实的依据
