听力原文： Elephants live mostly on grass, leaves and fruit. They also eat the twigs and bark of trees. The quantity of food and water which they consume is enormous, and they can be very destructive in their search for food, There are two main types of elephants. There is the Asiatic elephant, which is found in India, for example, and the African elephant. Superficially they are very much alike, but the African elephant is generally larger. One characteristic of Asiatic elephants is that they do not like being exposed to the sun, and consequently they prefer to live in shady places. They are also very fond of bathing. Apart from that, the most important difference between the two varieties is that the Asiatic elephant is more easily trained. Elephants in India, for example, have been caught and tamed for many hundreds of years. We have already noted that they have good memories, and it is this that makes them easy to train. Since they are immensely strong, they can carry and drag huge objects, such as the trees and rocks. This makes them extremely valuable as beasts of burden.

Proponents of green architecture argue that the approach has many benefits. In the case of a large office, for example, the combination of green design techniques and clever technology can not only reduce energy consumption and environmental impact, but also reduce running costs, create a more pleasant working environment, improve employee's health and productivity, reduce legal liability and boost property values and rental returns.
Green architecture, a term which only came into use in the 1990s, has its origin in the energy crisis of the 1970s, when architects began to question the wisdom of building enclosed glass-and-steel boxes that required massive heating and cooling systems. Early proponents of more energy-efficient architecture included William McDonough, Bruce Fowle and Robert Fox in America, Thomas Herzog in Germany, and Norman Forster and Richard Rogers in Britain.

Decide what types of evidence are used in the following argumentative paragraphs. A, fact B. statistics C. examples D. authority E. personal experience For example: Americans are downing close to 200 pounds of meat, poultry, and fish per capita per year, an increase of 50 pounds per person from 50 years ago. We each consume something like 110 grams of protein a day, about twice the federal government’s recommended allowance; of that, about 75 grams come from animal protein. It’s likely that most of us would do just fine on around 30 grams of protein a day, virtually all of it from plant sources. __B____ 1. The flow of spam(垃圾邮件) is often seasonal. It slows in the spring, and then in the month that technology specialists call “black September”--when hundreds of thousands of students return to college, many armed with new computers and access to fast Internet connections --the levels rise sharply.________ 2. Even sure-footed natives on a dark night could misjudge the lay of land，stumbling into a ditch or off a precipice. In Aberdeenshire, a 15-year-old girl died in 1973 after straying from her customary road through a churchyard and tumbling into a newly dug grave. The Yorkshireman Arthur Jessop, returning from a neighbor’s home on a cold January night, fell into a stone pit after losing her bearings. ________
71.It should be apparent, therefore, that a fully sealed cooling system would lose no water, consume no water, discharge no water and would not require the application of chemical treatment. Sealed water cooling systems are available and make it possible for a teacupful of water to do a job normally requiring millions of gallons of water.
Water Saver Systems is a company that has pioneered the principle of sealed industrial cooling in the UK and Europe. These sealed cooling systems, it is claimed, can actually provide payback within a matter of months because of the water and effluent cost savings and the removal of the need for a chemical treatment plant and the resultant chemical costs. In addition, it is possible to recover heat from a sealed system, allowing savings in boiler feed water and domestic hot water supplies. A further advantage is that grayish-materials build-up is prevented and rust minimized, so that the high efficiency of the sealed system is maintained and the service life in- creased. A significant merit of a sealed system, not yet fully appreciated, stems from the fact that industry can now be more mobile in terms of location. Traditionally, with some industries, a main consideration as regards a factory site would be the availability of a local high volume water supply for cooling purposes. 72. With a sealed system, it is claimed to be possible for a major user of cooling water to setup in the desert with only a small truck of water to give the sealed system its initial fill.
Sealed cooling systems also reduce water-related health risks. Chemical treatment does help to reduce such risks but for various reasons, chemicals have not yet provided total protection from disease. For example, Lehionnaires Disease which can be propagated via the evaporation taking place in cooling towers. Sealed systems do not emit contaminated vapour to atmosphere and this also means that thermal pollution does not occur.
73. Sealed industrial cooling systems were originally developed to offer efficient and cost-saving cooling alternatives to industry, giving considerable operational and financial advantages to the user. Fortunately, the development of the sealed cooling system also contributes significantly to the environment and health.

The first, a four-year international study led by researchers at the University of Newcastle, in Britain, and the Free University of Amsterdam, identifies several myths about the link between forests and water. For example, in arid and semi-arid areas, trees consume far more water than they trap. And it is not the trees that catch sediment and nutrients, and steady the flow of the rivers, but the fact that the soil has not been compressed.
The World Commission on Water estimates that the demand for water will increase by around 50% in the next 30 years. Moreover, around 4 billion people—one half of the world's population—will live in conditions of severe water stress, meaning they will not have enough water for drinking and washing to stay healthy, by 2025.
The government of South Africa has been taking a tough approach to trees since it became the first to treat water as a basic human right in 1998. In a scheme praised by the hydrologists, the state penalizes forestry companies for preventing this water reaching rivers and underground aquifers. In India, large tree-planting schemes not only lose valuable water but dim the true problem identified by the hydrologists: the unregulated removal of water from aquifers to irrigate crops. Farmers need no permit to drill a borehole and, as most farmers receive free electricity, there is little economic control on the volume of water pumped. So a report of Britain's Department for International Development concludes that there is no scientific evidence that forests increase or stabilize water flow in arid or semi-arid areas. It recommends that, if water shortages are a problem, governments should impose limits on forest plantation.
The second piece of research looked at how long the forests of the Amazon basin cling on to carbon. Growing trees consume carbon dioxide and it was thought that only when the tree died, perhaps hundreds of years later, would the carbon be returned to the atmosphere. No such luck. In a paper published in Nature this week, a team of American and Brazilian scientists found that trees were silently returning the carbon after just five years. Before taking an axe to trees, however, consider the merits of the tropical rainforests.
It is thought traditionally that trees
A．can improve the quality of atmosphere.
B．may lead to slow flowing of rivers.
C．will help wet and dry seasons to be unchanged.
D．are able to remove carbon from the soil.
Dieting
Dieting is one of those things that is completely integrated into American culture. On any given day, a huge portion of the U.S. population is "on a diet" and "counting calories" in one way or another.
Your Body's Efficiency
Have you ever wondered why, for so many people, weight gain seems to be a fact of life？ It's because the human body is way too efficient! It just does not take that much energy to maintain the human body at rest; and when exercising, the human body is amazingly frugal when it comes to turning food into motion.
At rest, the human body burns only about 12 calories per pound of body weight per day(26 calories per kilogram). That means that if you weigh 150 pounds(68 kg), your body uses only about:
150 X 12 = 1,800 calories per day
Twelve calories per pound per day is a rough estimate.
Those 1,800 calories are used to do everything you need to stay alive:
They keep your heart beating and lungs breathing.
They keep your internal organs operating properly.
They keep your brain running.
They keep your body warm.
In motion, the human body also uses energy very efficiently. For example, a person running a marathon(26 miles or 42 km)burns only about 2,60Ocalories. In other words, you burn only about 100 calories per mile(about 62 calories per km)when you are running.
Taking Calories In
The 1,800 calories that a typical person at rest needs per day is just not that many. Convenient food often takes the lead in our daily diets. In a typical day someone might consume some thing like this:
You might have two Pop-Tarts(r)for breakfast,
then hit Pizza Hut for lunch,
grab some Snack Well's and a cola for a snack,
head for McDonald's for dinner
and top it off with some potato chips while watching TV.
You can see how the number of calories coming in can easily reach 3,000, 4,000 or 5,000 per day without any effort at all. That's the problem.
Your body, it turns out, is extremely efficient at capturing and storing excess calories. Whenever your body finds that it has excess calories on hand, it converts them to fat and saves them for a rainy day. It only takes 3,500 excess calories to create 1 pound of new fat on your body.
The Idea Behind Dieting
To lose I pound of fat, what you have to do is burn off 3,500 calories. That is, over a period of time, you have to consume 3,500 calories less than your body needs. There are several ways you can Create that deficit. If you assume that you weigh 150 pounds and that your body at rest needs 1,800 calories per day(150 ~ 12 = 1,800)to live.
The only way to lose fat is to consume fewer calories per day than your body needs. For every 3,500 calories that your body takes from its fat reserves, you lose i pound(0.45 kg)of body fat. You can create the deficit either by monitoring and restricting your intake of calories, or by exercising, or both.
The idea behind most diet is simply to help you somehow lower the number of calories that you consume each day. That's all they do.
Why Diets Tend Not to Work
The reason why most diets tend not to work for very long is because they are not sustain able. A person gains weight because he or she consumes more calories per day than needed. The diet creates a temporary deficit. When the diet ends, the person goes back to normal eating and the weight comes back. What is needed instead is a sustainable diet m a food consumption and exercise plan -- that lets you live a normal life and eat normal foods in a normal way.
Building a Sustainable Diet
Building a. sustainable diet and exercise plan is the key to maintaining a consistent weight. This is not easy for many people. As descr

C．NG
Doctors usually don't recommend cutting back on the amount of food you eat, although your doctor may suggest better food choices, such as choosing foods with less fat and sugar in them. Because you are still growing, you need to keep eating and you also need to choose your foods wisely.
You can talk with your family and get everybody involved in eating better foods and exercising more. Keep your metabolism, or the rate at which you consume energy from food, at a high speed by staying active. The faster your body uses energy, which comes from food, the less likely you are to be at an unhealthy weight.
In fact, small changes in your diet and activities can add up to big changes in how you look and feel. For example, you can cut down on your TV, computer, or video game time by 30 minutes a day. Never skip breakfast and eat a good one with fruits, grains, and vegetables. Again, you can start a water habit. If you're thirsty, drink water instead of sugary juice, iced tea, or soft drinks.
Remember that not only will eating healthily and exercising more keep you at your ideal weight, you'll feel better about yourself, too. Now you're on your way to a lifetime of health!
Why is it important for you to be more active？
A．Because it reminds you of your weight.
B．Because it can get rid of your worries.
C．Because it is a good way to test your weight.
D．Because it helps you control your weight.
