【摘要】 可读性公式是评价文本难易程度的公式,能较客观地评价阅读材料的难度水平。对外汉语领域可读性公式研究比较缺乏。本文以初中级日韩学习者汉语记叙性短文的阅读理解成绩为因变量,利用经典研究范式建立了一个衡量记叙性文本难易度的可读性公式:Y=72.749-0.462X₃+0.802X₄-7.515X₅+2.446X₇（Y=可读性分数,X₃=总词数,X₄=简单词数,X₅=虚词数,X₇=分句数）,该公式可解释80.3%的变异,拟合优度高于同类公式。总词数、简单词数、虚词数和分句数是汉语文本难易度的重要预测指标。本文同时构拟了一个简单的可读性分数与适读水平对照表,供教学、研究参考。更多还原

【Abstract】 Readability formula is a formula assessing the difficulty of a text.Such studies in the field of teaching Chinese as a second language（TCSL）are comparatively inadequate.In this study,we chose elementary and intermediate South Korean and Japanese learners as subjects,take their results on the cloze tests of narrative text as dependent variable and build a new readability formula:Y=72.749-0.462X₃+0.802X₄-7.515X₅+2.446X₇（Y=readability score,X₃=total number of words,X₄=number of simple words,X₅=number of function words,X₇=number of sub-clause）.It can explain 80.3% variance,which is higher than other Chinese readability formulae.The four variables in the formula are important predictors when assessing difficulty of Chinese L2 reading materials.This article also builds a tentative grade chart for researchers’ reference.更多还原
