本研究基于评价理论，对一套广泛使用的小学英语教材中的价值观呈现进行积极话语分析。研究发现：1)从总体分布上看，一年级没有价值观呈现，二至四年级各有一到两个单元呈现价值观，五年级和六年级呈现价值的单元增多，各有四个和三个单元；从价值观类型上看，总共呈现了八种价值观，价值观呈现内容基本符合皮亚杰道德阶段论特点；2)除了保护动物这一价值观缺乏鉴赏资源外，其他均包括情感、鉴赏和判断这三种资源类型，且所有价值观中判断资源的数量最多；在判断资源中，社会约束类的数量远远超过社会评判类。研究结果有助于教材研究者了解国内小学教材中价值观的呈现特点，对教师和教材编写者也有一定启示作用。

This study adopts Appraisal Theory to conduct a positive discourse analysis of moral values in primary school English textbooks widely used in China. The study finds that: 1) Overall, there are no moral values represented in Grade One. From Grade Two to Grade Four, there is one or two moral values. In Grade Five and Grade Six, there are four and three moral values respectively. Totally there are eight types of moral values, the content of which conforms to Piagetian Moral Stage Theory. 2) Judgment resources take the largest proportion in all values. And in judgment, social sanction outnumbers social esteem. Apart from the lack of appreciation resources in the value of animal protection, the seven values all include affect, appreciation and judgment. The findings may be helpful for researchers to better understand the characteristics of moral values representation in Chinese primary school English textbooks and provide suggestions for future teaching practices and textbook development.
