The final sentences of a paragraph have two functions. First, they need to provide a conclusion, impact statement, or action statement relevant to the single idea of the paragraph. Second, they need to create a transition to the idea of the next paragraph.
This transition is created by using words and phrases relevant to the next idea or by specifically noting how the current idea relates to the next one. Let’s look at two examples.
End of paragraph one: “Throughout the grades, teachers build this disposition by asking questions that help students find the mathematics in their experiences, and by encouraging students to persist with interesting but challenging problems.”
Beginning of paragraph two: “Students who can successfully solve problems are able to apply and adapt a variety of appropriate strategies.”
[National Council of Teachers of Mathematics, 2000]
The first paragraph discusses teaching strategies, and the second discusses types of problem-solving strategies. The transition is created by the underlined words at the end of the first paragraph, which relates to the idea described in the context of the second paragraph.
I hope they will not come upon us now.
We are in God’s hands, brother, not in theirs.
[Shakespeare, Henry V, act 3, scene 6]
Gloucester’s comment discusses actions by the enemy, using the word “they.” This reference to the enemy creates a subtle transition to the beginning of Henry’s speech, which starts with a reference to the enemy: “theirs.”
