Now that you have refreshed your familiarity with some tools for building sentences by addition, see if you can revise the paragraphs below by combining the underlined sentences. Just as you did in the previous section, you will first practice the revision method (in this case, sentence combining) in part A of each question and then imitate sentence patterns in part B.
1A. In your notes, write a revision. When you are finished, check your understanding to compare your revision to a sample revision. If you need to review the strategies for combing sentences, refer to lesson “Revision Strategies: Strengthen Sentence Variety/Sentence Combining” in this module.
