有些汉字一字多音,不同的读法表示不同的意思。因此,数学教师为准确地表达数学思想,就应当掌握数学中一些常见的多音字的读法。数学中常见的多音字有以下几个: “长”。当动词时读作zhǎng如“增长”、“增长率”;当形容词时读作cháng,如“长度”、“长短”、“绳长”。 Some Chinese characters have multiple pronunciations and different reading mean different meanings. Therefore, mathematics teachers to accurately express mathematical ideas, we should master mathematics in some common polyphonic reading. Polyphony common in mathematics are the following: “long.” When the verb is read as zhǎng such as “growth”, “growth rate”; when adjectives read cháng, such as “length”, “length”, “rope length.”
