Analogies in science education can be related to the formation of new conceptual structure and the reconstruction of existed memory of students in learning. This paper was analyzed analogy-related contents included in high school biology Ⅰ, Ⅱ textbooks of the 7th science curriculum. The analogies were classified into the following criteria: regions of the textbook including analogies, types, explanatory ways, roles of analogies. Results of this study were as follower: A total of 573 analogies were found in the 7th biology Ⅰ, Ⅱ textbooks. More structural, verbal, concrete/concrete and simple analogies were included in the biology textbooks. When the analogies were explained in the textbooks, the term "analogy", limitations of analogy and causal relations were rarely mentioned. But the analogies related to everyday contexts were frequently used. More than 70% of analogies took roles as understanding aids. The number of analogies used varied considerably according to the publishing company and the domain. Small number of analogies were commonly used in almost all kinds of textbooks, but newly developed ones were used in only one kind of textbook. To help students' effective understanding of various biology concepts, it is necessary to develop more systematic analogies and research the application of analogy.
