Given that 8 percent of food crops grows faster on farms using groundwater

than the aquifers are replenished, and many large rivers are so heavily diverted

that they do not reach the sea for much of the year, researchers believe

freshwater sources--underground aquifers and rivers--are stressed. Better

(5) management of soil and water and creative cropping patterns can boost

production from rainfall-watered cropland, but the heaviest burden will fall on

irrigated land. At present, most farmers irrigate their crops by channeling

water down their fields in parallel furrows.

One alternative, drip systems, enables farmers to deliver water directly to

(10) the plants' roots drop by drop, nearly eliminating waste by distributing water at

low pressure through a network of perforated plastic tubing installed on or

below the surface of the soil, where it then emerges through small holes at a

slow but steady pace. Because the plants enjoy an ideal moisture environment,

drip irrigation usually offers the added bonus of higher crop yields. Another

(15) alternative, sprinklers, can perform. almost as well as drip methods when

designed properly, but traditional high-pressure irrigation sprinklers spray

water high into the air to cover as large a land area as possible, and the more

time the water spends in the air, the more of it evaporates before use.

Despite the payoffs, the higher costs of these technologies relative to

(20) simple flooding methods have been a barrier to their spread, and so has the

prevalence of national water policies that discourage rather than foster efficient

water use. Many governments have set very low prices for publicly supplied

irrigation, leaving farmers with little motivation to invest in ways to conserve

water or to improve efficiency and most authorities have also failed to regulate

(25) groundwater pumping, even in regions where aquifers are over-tapped.

Therefore, farmers might be inclined to conserve their own water supplies if

they could profit from selling the surplus, but this practice is often discouraged.

Efforts aside from irrigation technologies are also conducive to the

reduction of agricultural demand for water; for instance, measurements of

(30) climate factors such as temperature and precipitation can be fed into a computer

that calculates how much water a typical plant is consuming, and farmers can

use this figure to determine, quite accurately, when and how much to irrigate

their particular crops throughout the growing season. But the most effective, if

unlikely way, to do more with less water is to reconfigure our diets, especially

(35) the typical North American diet, which, with its large share of animal products,

requires twice as much water as diets common in many Asian and some

European countries. Eating lower on the food chain could allow the same

volume of water to feed two Americans instead of one, and despite the resultant

loss of nutrition, this may be the only recourse for countries serious about

(40) reducing their aquifer strain.

The primary purpose of the passage is to

A．expose the fragile ecological conditions which modern irrigation technologies must ameliorate

B．argue that new irrigation technologies would ultimately be less efficient than a reconfiguration of the North American diet

C．argue that efficient water-use is dependent upon a mixture of various modern methods

D．provide an overall view of possible methods for lessening the strain on sources of freshwater

E．describe the cycle by which aquifers are depleted and then replenished through technology

d lack of consumer demand for environment(环境)friendly products have contributed to the pollution problem. One result is that mil lions of tons of glass, paper, plastic, and metal containers are produced, and these are difficult to get rid of.

However, today, more and more consumers are choosing" green" and demanding that the products they guy should be safe for the environment. Before they buy a product, they ask questions like these:" Will this shampoo damage the environment？" "Can this metal container be reused or can it only be used once？"

A recent study showed that two out of five adults now consider the environmental safety of a product before they buy it. This means that companies must now change the way they make and sell their products to make sure that they are "green", that is, friendly to the environment.

Only a few years ago, it was impossible to find green products in supermarkets, but now there are hundreds. Some supermarket products carry labels (标签)to show that the product is green. Some companies have made the manufacturing(生产) of clean and safe products their main selling point and emphasize it in their advertising.

The concern for a safer and cleaner environment is making companies rethink how they do business. No longer will the public accept the old attitude of "Buy it, use it, throw it away, and forget it". The public pressure is on, and gradually business is cleaning up its act.

What has caused the pollution problem？

A．Careless methods of production.

B．Lack of consumer demand for environment friendly products.

C．Millions of tons of glass, paper, plastic and metal containers are produced.

D．Both A and B

Questions 1 to 5 are based on the following passage:

There are two methods of fighting, the one by law, the other by force; the first method is that of men, the second of beasts; but as the first method is often insufficient, one must have recourse to the second. It is, therefore, necessary for a prince to know well how to use both the beast and the man. This was covertly taught to rulers by ancient writers, who related how Achilles and many others of those ancient princes were given to Chiron the centaur to be brought up and educated under his discipline. The parable of this semi animal, semi human teacher is meant to indicate that a prince must know how to use both natures, and that the one without the other is not durable. A prince, being thus obliged to know well how to act as a beast, must imitate the fox, and the lion, for the lion cannot protect himself from traps, and the fox annot defend himself from wolves. Those that wish to be only lions do not understand this. Therefore, a prudent ruler ought not to keep faith when by doing so it would be against his interest, and when the reasons which made him bind himself no longer exist. If men were all good, this precept would not be good ; but as they are bad, and would not observe their faith with you, so you are not bound to keep faith with them. Nor have legitimate grounds ever failed a prince who wished to show colorable excuse for the nonfulfilment of his promise. Of this one could furnish an infinite number of examples, and show how many times peace has been broken, and how many promises rendered worthless, by the faithlessness of princes, and those that have best been able to imitate the fox have succeeded best. But it is necessary to be able to disguise this character well, and to be a great feigner and dissembler, and men are so simple and so ready to obey present necessities, that the one who deceives will always find those who allow themselves to be deceived. The author of the passage does not believe that ____

A.A.people can protect themselves

B.B.the truth makes men free

C.C.leaders have to be consistent

D.D.princes are human
