[解析]
(1)B.细节理解题。根据前三段的描述第一段的:it's good to get along well with your teacher和你的老师相处得很好。第二段的:it's smart to learn how to get along well with the different types of people学会如何与不同类型的人相处融洽是很明智的。第三段的:kids who get along well with their teachers not only learn more,but they're more comfortable with asking questions and getting extra help.与老师相处融洽的孩子不仅学习更多,而且更乐于提问和获得额外帮助。可知,如果与老师处好关系,在校期间你就会更愉快。故选B。
(2)C.猜测词义题。根据第四段If you show your teacher that you want to make the situation better,he or she will probably do everything possible to make that happen如果你让你的老师知道你想让情况好转,他或她很可能会尽一切可能让情况好转。可知,如果你向老师展示你想让事情更好,那么,老师也会竭尽所能使师生关系更好的,由此可知,that此处指代的是"a better relationship between you and your teacher"更好的师生关系。故选C。
(3)A.推理判断题。从横线后面所列举出的学生应该履行的一些责任可以看出,如果你履行了这些基本职责的话,即使你不很喜欢那个老师,你也可以和他/她成功相处,结合选项,故选A。
