From "The Ugly Duckling" by E. Louise Smythe

Analysis Key

     A duck made her nest (DO) {under some leaves}. |

     She sat {on the eggs} to keep them warm [#1]. |

     {At last} the eggs broke, one {after the other} [#2]. | Little ducks came

out. |

     Only one egg was left (P). | It was a very large one (PN). |

     {At last} it broke, | and out came a big, ugly duckling. |

     [DO of "said" "What a big duckling!"] [#3] said the old duck. | "He does

not look {like us}. | Can he be a turkey (PN)? | We will see. | [Adv. to "not"

If he does not like the water (DO)], he is not a duck (PN)." |

     The next day [NuA] the mother duck took her ducklings (DO) {to the pond}. |

1. "Warm" is a predicate adjective in an ellipsed infinitive construction "them *to be* warm." "Them" is the subject of the infinitive, and the infinitive phrase functions as the direct object of the infinitive "to keep." That infinitive phrase functions as an adverb (of purpose) to "sat." [It answers the question "Sat why?"]
2. Within KISS, there are two ways to explain this "one." First, it can be considered an appositive to "eggs." Second, it can be explained as a noun used as an adverb. The phrase "after the other" here is an adjective, simply because it obviously connects to the pronoun "one." Note that the appositive is a reduction of a clause "One *broke* after the other." In this full form, "after the other" functions as an adverb to broke."
3. Expect the students to be confused by this clause that functions as a direct object.
