Activity (Adding Details to Complete an Essay), 70–73 Answers will vary; possible supporting details are included in the paragraphs below. First of all, with no television to compete for our time, we found plenty of hours for personal interests. We all read more that week than we had read during the six months before.Dad introduced Mom to his favorite mystery writer—Dorothy Sayers—and it was pleasant to see them sitting on the sofa together, each one absorbed in a book. Luella, serious as always, read novels by Charles Dickens, while I settled modestly for the daily newspapers. We each also enjoyed some hobbies we had ignored for ages.Mom and Dad did crossword puzzles together, Lu dusted off her stamp collection, and I finished knitting the sweater I had started last September. In addition, my sister and I both stopped procrastinating with our homework.Instead of putting off our English and math assignments until our favorite shows were over, we tackled them right after supper and found that, without the sound of the TV blaring in our ears, we could do them in a couple of hours—far more quickly than we expected. Second, we did chores that had been hanging over our heads for too long. There were many jobs around the house that had needed attention for some time.Mom fixed a faucet that had been dripping for weeks while Dad patched the cracked plaster in the dining room. Lu and I cleaned our closets, finding records, tapes, and magazines that had been missing for months. By the end of the week, the house was in tidier shape than it had been since we moved in. We also had a chance to do some long-postponed shopping.Mom and Dad picked out a new sofa for the den; Lu bought some new books, and I went through a whole stack of catalogs and finished all my Christmas shopping by mail. And each of us also did some letter writing or other paperwork that was long overdue. Mom and Dad struggled with this year’s income tax forms, Lu wrote to Johnny, a friend she met at Spirit Lake last summer, and I wrote a thank-you note to Aunt Elsie for letting me stay with her during my weekend in New York City last month. Finally, and probably most important, we spent time with each other. Instead of being in the same room together while we stared at a screen, we actually talked for many pleasant hours. Mom told us about the programming project she has been doing at work, and we had fun planning the trip to Boston we are going to take this summer. Moreover, for the first time in years my family played some games together. We played several games of Scrabble, and we even got out the Monopoly set and played a game following the rules our family has made up over the years. And because we didn’t have to worry about missing this or that show, we had some family friends over a couple of evenings and spent an enjoyable time with them.We were glad to see how much the Overholt children had grown, and Joe and Sandy Ciprianni kept us laughing all evening with their stories about fixing up the old house they bought. 4 The Third Step in Essay Writing Fill-ins (Common Methods of Organization), 75–76 The topic sentences in the essay use the words time order. help show emphatic order.
