. the amount of; C. a number of} salt in fresh water used on coastal farms. As a result farmers are increasingly {A. unable; B. able; C. possible} to use fields close to the sea.
Scientists call this process “salinization” which means a mixture of salt and water. Salinization is reducing the world’s irrigated lands {A. to; B. by; C. at} 1 to 2 percent every year.
But a farmer in the Netherlands is now using a mixture of sea and fresh water to grow healthy and tasty vegetables. Marc Van started with an {A. investment; B. examination; C. experiment}. “We put in a lot of plants in the fields and then we put in, put them in fresh water and in sea water and all the varieties between it, and then we see which variety is surviving and which variety is {A. living; B. dead; C. dying}.”

More than one in ten people who are regularly exposed to organophosphate pesticides(有机磷酸脂农药) will suffer unrecoverable physical and mental damage, a team of psychiatrists warns. The investigators say that theirs is the first serious attempt to estimate the number of people suffering because of chronic low-level exposure to the pesticides.
"This is a worrying high level of illness," says one researcher. The findings by the researcher, who also treats many of the victims, conflict with those of the Britain's government agency monitoring occupational health, which says there is no good evidence to suggest chronic exposure leads to widespread illness. The research team sent questionnaires to 400 farmers selected at random from a phone book. Of 179 who replied, 130 reported that they had been exposed to organophosphates. And 21 farmers complained of enough symptoms to be classed as suffering from organophosphate poisoning. Allowing for bias inherent in the survey method, they suggest that around 10 percent of farmers exposed to the pesticides suffer from poisoning.
The researchers also uncovered a consistent pattern of symptoms ranging from extreme tiredness and speech difficulty to suicidal impulses. Again this contrasts with the government agency's view that there is no clear pattern of symptoms for pesticide poisoning, making a diagnosis difficult.
They believe the real figure for poisoning is much higher, once you include cancers and heart disease linked to the pesticide. Last year, British specialists also found evidence of a link between organophosphates and severe bone abnormalities in eight men. One of the researchers, Anthony Lyons of Queen's Medical centre in Nottingham, says preliminary results from a larger follow-up study suggest the extent of bone damage may be worse than they feared.
All those who suffer from organophosphate poisoning complain of becoming "exquisitely sensitive" to any further exposure. This is bad news for any Gulf War veterans sent back to the Middle East. Many scientists and doctors are convinced that Gulf War Syndrome is at least partly caused by organophosphate pesticides, which were sprayed in tents and on clothes to protect troops from biting insects.
A spokesman for Britain's Ministry of Defense says there are no immediate plans to send ground troops to the Gulf. But the US is moving 5,000 troops into the region. Returning troops "would be more vulnerable to poisoning", says one of the leading US authorities on such poisoning.
In which area do the findings of the researchers have confliction with those Britain's Health and Safety Executive(HSE), the government agency monitoring occupational health？ ______.
A．Whether exposure to organophosphate will do any harm to man
B．Whether chronic exposure to organophosphate would lead to widespread illness
C．Whether it is worthwhile to find out the number of people suffering from organophosphate poisoning
D．Whether organophosphate is a good pesticide
This typifies the way in which engineers work to help people and create a better quality of life. The fact that this country has the most efficient agricultural industry in the world is another good example. Mechanical engineers have worked with farmers and biologists to produce fertilizers, machinery and harvesting systems. This team effort has now produced crops uniformly waist high or less so that they are better suited to mechanical harvesting. Similar advances with other crops have released people from hard and boring jobs for more creative work, whilst machines harvest crops more efficiently with less waste. Providing more food for the rapidly increasing population is yet another role for the mechanical engineer.
According to the passage, when would most weight be imposed on hip-joints？
A．When one is walking.
B．When one is running.
C．When one is standing.
D．When one is lying down.
The recent growth of export surpluses on the world food market has certainly been unexpectedly great, partly because a strange sequence of two successful grain harvests in North America is now being followed by a third. Most of Britain's overseas suppliers of meat, too, are offering more this year and home production has also risen.
But the effect of all this on the food situation in this country has been made worse by a simultaneous rise in food prices, due chiefly to the gradual cutting down of government support for food. The shops are overstocked with food net only because there is more food available, but also because people, frightened by high prices, are buying less of it.
Moreover, the rise in domestic prices has come at a time when world prices have begun to fall, with the result that imported food, with the exception of grain, is often cheaper than the home-produced variety. And now grain prices, too, are falling. Consumers are beginning to ask why they should not be enabled to benefit from this trend.
The significance of these developments is not lost on farmers. The older generations have seen it all happen before. Despite the present price and market guarantees, farmers fear they are about to be squeezed between cheap food imports and a shrinking home market. Present production is running at 51 per cent above pre-war levels, and the government has called for an expansion to 60 per cent by 1956; but repeated Ministerial advice is carrying little weight and the expansion program is not working very well.
Why is there "wide-spread uneasiness and confusion" about the food situation in Britain？
A．Despite the abundance, food prices keep rising.
B．The abundant food supply is not expected to last.
C．Britain will cut back on its production of food.
D．Britain is importing less food.
The smallest bat in the world is from Southeast Asia.This kind of bat measures about 30 millimeters in length. The world's largest bat, the Giant Golden-Crowned Flying Fox, has a wingspan of 1.5 meters.Most bats eat insects,but many feed on fruit or nectar from flowers.
Many people think bats are blind,but this is not true.Many species have very good sight.Most bats communicate and find their way by making"echolocation" (回声定位法 ) noises.They produce high-frequency noises and can estimate the distance of an object by using the sound echoes that bounce back to them. So, while bats may travel in total darkness, they"see"using sound.
Sadly, bats are widely feared and misunderstood. Most bats come out of their shelters only at nightfall. Three bat species feed on blood. Because of these qualities, bats have long been linked in many cultures to death, darkness and blood-drinking.
Yet bats are important for agriculture and our environment. They help pollinate (授粉)plants and spread seeds. They also help control insects. Bats eat huge numbers of insects,including kinds that damage crops.
For example, a brown bat can eat more than 1,000 insects in one hour.Onereport says bats save American farmers billions of dollars every year by reducing crop damage and limiting the need for chemicals that kill insects.
Over one-fifth of all bat species are under threat. They face disease and the human destruction of their natural environments.In some areas, diseases have killed nearly 100% of bat populations.

The review study,"Organic Agriculture in the 21st Century,”is featured as the cover story for theFebruary issue of the journal Nature Plants. It is the first to compare organic and conventional agricultureacross the main goals of sustainability identified by the National Academy of Sciences: productivity,economics，and environment.
Critics have long argued that organic agriculture is inefficient，requiring more land to yield the sameamount of food. It's true that organic farming produces lower yields，averaging 10 to 20 percent less thanconventional. Advocates contend that the environmental advantages of organic agriculture far outweighthe lower yields，and that increasing research and breeding resources for organic systems would reduce theyield gap.Sometimes excluded from these arguments is the fact that we already produce enough food tomore than feed the world's 7.4 billion people but do not provide adequate access to all individuals
In some cases，organic yields can be higher than conventional. For example，in severe droughtconditions，which are expected to increase with climate change in many areas，organic farms can produceas good，if not better，yields because of the higher water-holding capacity of organically farmed soils.
What science does tell us is that mainstream conventional farming systems have provided growingsupplies of food and other products but often at the expense of other sustainability goals.
Conventional agriculture may produce more food，but it often comes at a cost to the environment.Biodiversity loss，environmental degradation，and severe impacts on ecosystem services have not onlyaccompanied conventional farming systems but have often extended well beyond their field boundaries.With organic agriculture，environmental costs tend to be lower and the benefits greater.
Overall，organic farms tend to store more soil carbon，have better soil quality， and reduce soil erosioncompared to their conventional counterparts. Organic agriculture also creates less soil and water pollutionand lower greenhouse gas emissions. And it's more energy-efficient because it doesn't rely on syntheticfertilizers or pesticides.
Organic agriculture is also associated with greater biodiversity of plants，animals，insects andmicroorganisms as well as genetic diversity. Biodiversity increases the services that nature provides andimproves the ability of farming systems to adapt to changing conditions.
Despite lower yields，organic agriculture is more profitable for farmers because consumers are willingto pay more.Higher prices，called price premiums，can be justified as a way to compensate farmers forproviding ecosystem services and avoiding environmental damage or external costs.
