摘要
在新版《新概念英语》第四册第33课的课文中,出现了这样一句话:Education, with its cycles of instruction so carefully worked out, punctuated by textbooks--those purchasable wells of wisdom--what would civilization be like without its benefits? (教育,以其教学周期如此精心地安排,并以教科书——那些可以买到的智慧源泉——予以强化,如果不受其惠,文明将会是个什么样子呢?)教材后的注释是:这句话中的主语education与punctuated并不是一种主谓关系,这句话在语法上被称作“单部句”。
