澳大利亚中小学的课本是“公用”的。按当地的法规,课本必须一届一届传承,直到不能用为止。即使某些内容过时了,也只能多几张修订的“活页”,而“活页”也要届届相传。学生放假时,都必须将课本交还学校。教科书不是用过后就消失的东西,只要爱惜,多用两三次一般不会有问题。所以 Australian primary and secondary school textbooks are “public”. According to local regulations, textbooks must be passed down once and for all until they cannot be used. Even if some of the contents are outdated, only a few more revised “leaflets” will be available, and “leaflets” will also be passed down. When students leave, they must return the textbooks to the school. Textbooks are not things that disappear after they are used. As long as you cherish them, there are usually no problems with using them two or three more times. and so
