11、眼睛。那它怎么看东西呢？是每个小眼睛都看到一个小形象，合成一个大形象？还是每个小眼睛看到形象的一部分，合成一个完整的形象？总是琢磨不出来。（第一自然段）,“一直”“琢磨”说明“我”对昆虫的“复眼是怎么回事”这个问题产生了浓厚的兴趣，并执着地想弄清楚其中的奥秘。,一连串的疑问，照应了前文“我”“一直在琢磨复眼是怎么回事”，表现了“我”的好奇，以及对问题刨根问底的性格特点。,凡（fn）是有复眼的昆虫，视觉都很灵敏。蜻蜓就有复眼，苍蝇（yn）也有。你走近蜻蜓和苍蝇，还有一段距（j）离，它们就发现了，噌（cn）飞了。（第二自然段）,这句话是本段的中心距句，本段后面的内容都是围绕这句话来写的。,“凡是都
