【简答题】
The box that follows summarizes the six kinds of introductions. Decide which kind each paragraph uses. Write down A, B, C, D, E, or F. A. General to narrow B. Starting with an opposite C. Stating importance of topic D. Incident or story E. Questions F. Quotation _____ 1. The ad, in full color on a glossy magazine page, shows a beautiful kitchen with gleaming counters. In the foreground, on one of the counters, stands a shiny new food processor. Usually, a feminine hand is touching it lovingly. Around the main picture are other, smaller shots. They show mounds of perfectly sliced onion rings, thin rounds of juicy tomatoes, heaps of matchstick-sized potatoes, and piles of golden, evenly grated cheese. The ad copy tells you how wonderful, how easy, food preparation will be with a processor. Don’t believe it. My processor turned out to be expensive, difficult to operate, and very limited in its use. _____ 2. My father stubbornly says, “You can often tell a book by its cover,” and when it comes to certain paperbacks, he’s right. When you’re browsing in the drugstore or supermarket and you see a paperback featuring an attractive young woman in a low-cut dress fleeing from a handsome dark figure in a shadowy castle, you know exactly what you’re getting. Every romance novel has the same elements: an innocent heroine, an exotic setting, and a cruel but fascinating hero. _____ 3. We Americans are incredibly lazy. Instead of cooking a simple, nourishing meal, we pop a frozen dinner into the oven. Instead of studying a daily newspaper, we are contented with the capsule summaries on the network news. Worst of all, instead of walking even a few blocks to the local convenience store, we jump into our cars. This dependence on the automobile, even for short trips, has robbed us of a valuable experience— walking. If we drove less and walked more, we would save money, become healthier, and discover fascinating things about our surroundings.
