English Skills with Readings 8th Edition by John Langan

Exercise 15

The following activity will give you practice in writing an accurate point, or topic sentence-one that is neither too broad nor too narrow for the supporting material in a paragraph. Sometimes you will construct your topic sentence after you have decided which details you want to discuss. An added value of this activity is that it shows you how to write a topic sentence that will exactly match the details you have developed.
Topic sentence: __________________________________________________________________________________________________________________
a. The crowd scenes were crudely spliced from another film.
b. Mountains and other background scenery were just painted cardboard cutouts.
c. The "sync" was off, so that you heard voices even when the actors' lips were not moving.
d. The so-called monster was just a spider that had been filmed through a magnifying lens.
