《论雷峰塔的倒掉》中有一道预习题：“读准下列加点字的音”，其中有“贝壳”与“地壳”，对于这两个“壳”，学生查字典得知分别念k6与q伯。。但课文中的“蟹壳”的“壳”怎么意呢7学生拿不准。这就要求教师对“壳”的多音读法加以指导。先看《现代汉语词典》（1983年版）里 There is a preparatory question in “The Fall of Leifeng Tower”: “Read the punctuality of the following words,” including “shell” and “crustal”. For these two “shells”, the students learn to read the dictionary separately. K6 and q. . But what does the “shell” of “crab shell” in the text mean? 7 students are not sure. This requires teachers to guide the polyphonic reading of the “shell.” Look at the “Modern Chinese Dictionary” (1983 edition)
