Experts in the food industry are thinking a lot about trash(垃圾) these days. Restaurants, colleges, hospitals and other institutions are making up for the rising costs of waste in new ways. Some are tracking their trash with software systems making food in smaller amount or trying to cut down on trash-hauling(托运)costs. Roughly 30% percent of food in the United States goes to waste, costing some $48 billion annually according to a Stockholm International Water Institute study. A 2004 University of Arizona study estimated that 40 to 50 percent of food in the United States is wasted. Freshman students at Virginia Tech were surprised this year when they entered two of the campus’s biggest dining halls to find there were no cafeteria trays. Getting rid of trays has cut food waste by 38% percent at the cafeterias, said Denny Cochrane, manager of Virginia Tech’s sustainability program. Before the program began, students often grabbled whatever looked good at the canteen, only to find at the table that their eyes were bigger than their stomachs, he said.
That same phenomenon often happens at Oregon’s Portland International Airport. Busy travelers often throw half-eaten meals into trash cans, adding dozens of tons of waste that the airport must pay the city to haul away. Now the airport is carrying out a program to install food-only trash carts. The food waste is collected in biodegradabe(可生物分解的) bags and given to the city to use as compost(堆肥). Besides being environmentally friendly, the changes may save the airport money. It costs about $82 to have one ton of trash hauled from the airport to the city landfill(垃圾掩埋场). But food waste costs about $48 a ton to haul.
Cutting back on the waste can require spending money on software and training. LeanPath, based in Portland, Ore, sells a software system to track food being thrown out. Steve Peterson, head chef at the MGM Grand hotel in Las Vegas, said he was surprised when he installed the LeanPath system and saw the value of food that was going out the back door. To cut costs, Peterson decided to reduce serving sizes. He said customers weren’t bothered by the switch, which has helped him lower food waste by between 15 to 20 percent over 18 month.
73. The main reason for people paying attention to food waste is ______________.
A. to lower the cost of food waste B. to save more food for the world.
C. to keep the dining room clean D. to reduce the effort of cooking
74. What kind of measure has been taken to cut food waste?
A. Making cafeteria at colleges and universities trayless.
B. Using software system to trace the location of the trash.
C. Trying to remove the food waste little by little.
D. Charging higher prices for smaller amount of food.
75. What’s the benefit of installing food-only trash cans at the airport?
A. Keeping the airport clean and tidy.
B. Fastering the process of making trash into compost.
C. Reducing the cost of removing the trash.
D. Reminding the passengers to produce less trash.
76. In which way can software help reduce the food waste?
A. It can store varieties of measures for people to choose.
B. It can help people to be informed of the food waste.
C. It can calculate the total amount of the food offered.
D. It can connect the food needed with the data of customers.
77. What is the passage mainly about?
A. Great amount of food is wasted at public places.
B. Individuals don’t pay attention to food waste.
C. It costs big money to handle food waste.
D. Lots of new methods are taken to deal with food waste.

阅读快车系列答案If you have to miss one meal a day, which meal will cause you fewest health problems if you don’t eat it? If they have to make a decision of this type, most people (especially very busy people) will choose to skip (not to eat) breakfast.
However, many experts in the field of health consider breakfast (the meal which “breaks” your “fast---- a period of time without eating anything ” which started the night before) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients we need to begin our working day with vigor and hopefully with good humour. But many people skip breakfast or replace it with snacks or a cup of coffee for a well-balanced meal. What happens if we ignore the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants included both males and females who ranged in age from 12—83. During the experiment, these people were given a variety of breakfasts, and sometimes, they had to skip breakfast completely. Special tests, including blood tests and endurance tests, were set up to analyze how well the participants’ bodies functioned when they had eaten a certain kind of breakfast.
The result showed that if a person eats an adequate (充足的) breakfast, he or she will work more efficiently and more productively than if he or she skips breakfasts or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental activity. The study showed that if schoolchildren eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast diet is inadequate .
The study also showed that, contrary to what many people believe, if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you are on a diet, skipping breakfast will not help you. You will probably lose more weight if you reduce your other meals.

Humanity uses a little less than half the water available worldwide. Yet occurrences of shortages and droughts (干旱) are causing famine and distress in some areas, and industrial and agricultural by-products are polluting water supplies. Since the world’s population is expected to double in the next 50 years, many experts think we are on the edge of a widespread water crisis.
But that doesn’t have to be the outcome. Water shortages do not have to trouble the world---if we start valuing water more than we did in the past. Just as we began to appreciate petroleum more after the 1970s oil crises, today we must start looking at water from a fresh economic perspective. We can no longer afford to consider water a virtually free resource of which we can use as much as we like in any way we want.
Instead, for all uses except the domestic demand of the poor, governments should price water to reflect its actual value. This means charging a fee for the water itself as well as for the supply costs.
Governments should also protect this resource by providing water in more economically and environmentally sound (健康的) ways. For example, often the cheapest way to provide irrigation water in the dry tropics is through small-scale projects, such as gathering rainfall in depressions (凹地) and pumping it to nearby cropland.
No matter what steps governments take to provide water more efficiently, they must change their institutional and legal approaches to water use. Rather than spread control among hundreds or even thousands of local, regional, and national agencies that watch various aspects of water use, countries should set up central authorities to coordinate (调整) water policy.
【小题1】What is the real cause of the potentials water crisis.
| A．Only half of the world’s water can be used. |

| A．is already serious in certain parts of the world. |
| B．has been exaggerated by some experts in the field |
| C．poses a challenge to the technology of building reservoirs(水库) |
| D．is underestimated by government organizations at different levels |
| A．be reduced to the minimum | B．stimulate domestic demand |
| C．go with its real value | D．take into account the occurrences of droughts |
| A．guarantee full protection of the environment |
| B．centralize the management of water resources |
| C．increase the sense of responsibility of agencies at all levels |
| D．encourage local and regional water resources |
