What this lesson teaches

Long sentences often go wrong in the middle. This lesson builds three habits that fix that. First, find the head of a long subject and make the verb agree with it.

Second, let the word before a gap choose the pattern that follows (want me to, have to pay, worth visiting). Third, keep every describing word next to the word it describes.

In Build a Sentence, these habits tell you where each tile attaches, and which of two look-alike tiles is the extra tile.

By the end of the lesson, you can

  1. Find the head noun of a long subject and make the verb and pronoun agree with it: each of the + plural → singular (has, its); the number of → singular; a number of → plural; everyone who → singular, also inside the who-clause.
  2. Use the pattern the word before demands: want / would like / ask + person + to + verb; have to and modals + base verb; worth + ‑ing. Put modifiers in place: a phrase straight after its noun, adjectives in the order size → age → shape → color → origin → material, and intensifiers (much, far, that much, every single, just) directly before the word they strengthen.
  3. In Build a Sentence, ask what each tile attaches to, including fixed words in the middle of the reply (of, that), and leave the twin form (has/have, pay/paying, borrow/borrows) as the extra tile.
