For the 75 cities studied, researchers added up all the extra time and fuel wasted because of traffic congestion. The price tag they figure is almost $68 billion a year. Task 10【答案】I.A. mon。s just the extra time spent going slow or going nowhere because of traffic congestion. The study says the worst traffic is in Los Angeles where the average rush hour driver loses 136 hours a year, more than three work weeks, to traffic jams. The runners up in the time drained category San Francisco, ., Seattle, Houston, San Jose, Dallas, New York, Atlanta and Miami where the average rush hour driver loses an extra 69 hours a year stuck in traffic. Once you get to a big system, it39。s a lot more demand than there is supply. The annual Urban Mobility Report from the Texas Transportation Institute finds in the average American city people traveled 85 percent more miles by car in the year 2000 than they did in 1982. And rush hour drivers are now wasting an average of 62 hours a year stuck in traffic. Now that39。s the amount of people, the amount of roadway that is there. It39。re probably right.

After you eat the food, you can just throw them away. 6) The writer is mildly criticizing the trend toward onetrip living and thinks it probably has gone too far.【原文】The product that most people throw out after using only once is packaging. This is not always tree. The pottery or metal container used in Roman times and in most rural areas of the world today is a permanent and valuable household item. Unless a container is accidentally broken, it lasts a lifetime, despite the many journeys from home to market, farm or water well and back. The growth of large cities and modem methods of food production changes all that. Because the food must be shipped from place to place while it is produced, and because of the increased variety of foods available and the convenience of precooked meals, it is impossible for the customer to collect many foods in his own container. It costs a great deal to provide a new container each time we buy milk, wine, beer and other drinks. Yet for a number of reasons the trend towards onetrip bottles for all these items is in full swing. The case of the vanishing returnable softdrink bottle shows how much these containers add to the rising tide of waste. Until the late 1950s, Americans had to borrow softdrink bottles by paying a deposit each time they bought one. But several years later, softdrink bottlers decided that it was more convenient for the customer to throw the bottle away instead. A returnable bottle lasting 30 or more trips was replaced with 30 onetrip cans or bottles. Sales of soft drinks climbed and the container manufacturers smiled all the way to the bank. Glass panies gave softdrink sellers a helping hand.
