If the apple recognizer has seen A-P-P-L, it'll think to itself, "Hmm, I think an E is probably likely," and it'll send a signal down to all the E recognizers saying, "Be on the lookout for an E, I think one might be coming."
如果那个认出apple的看到 a-p-p-l， 它就会想，“嗯，我觉得接下来是e,” 然后它就会把信号传送个所有认知e的 说，“看住e， 我觉得它就要来了。”
