1. Weird food:They like little locust which is pan-fried or fried. Pollywog is also a kind of food here. 怪异的食物》类似蚂蚱幼虫的食物，好像是炒或炸来吃，蝌蚪也是当地的食物。
2. A bowl of noodle and a bowl of puffed ginger, a basin of pollywog and a basin of locust are all seemingly by our side. 一碗小面、一碗泡姜、一盆蝌蚪、一盆蚂蚱，仿佛就在读者身边。
3. The cybernetic difference between an organism such as a pollywog and an ecosystem such as a fresh-water bog is that an organism is tightly bound, and strict; an ecosystem is loosely bound, and lax. 从控制论的角度看，象蝌蚪这样的有机体和淡水沼泽这样的生态系统之间控制方式的不同在于，单个有机体受到严格紧密的束缚，而生态系统则宽松自由，不受束缚。
