Passage 1Of Ducks and Duck Eggs For people who like to keep poultry, ducks offer certain advantages over hens. Ducks are immune to some common diseases found in hens and are less vulnerable to others. Some breeds of duck produce bigger eggs than hens. In addition, ducks lay eggs over a longer season than hens do. Poultry keepers with gardens have less to worry about if they keep ducks rather than hens because the former are less apt to dig up plants and destroy roots. While both hens and ducks benefit the garden by eating pests, hens are known to damage herb and grass beds. Ducks, on the other hand, will search for insects and snails more carefully. Only very delicate plants are at risk from the broad, webbed feet of ducks. Like all waterbirds, ducks need access to water, and duck keepers typically provide this by building a pond. Something this large is not absolutely necessary, however, ducks need only to be able to dip their heads in the water to keep their nostrils clean. If a pond is provided though it is important to keep ducklings away from it until they are old enough to withstand the cool temperature of the water-about eight weeks. When keeping ducks, one has to consider just how many the land will support. Generally the rule is 100 ducks per-half hectare. If more than this proportion is introduced, there is a risk of compacting the soil, which can lead to muddy conditions for long periods as the rain is not easily absorbed into the ground. While ducks offer many advantages over hens, they must be given greater quantity of food, especially if regular eggs are desired. An adult duck will eat between 170 to 200 grams of food a day. If the ducks have access to grass and a pond, they will be able to find for themselves approximately 70% of their daily dietary, requirements in warmer months but less than half that in colder times. Therefore, it is important that they are fed enough food, such as grain, every day. Experienced duck keepers raise ducklings every three years or so because it is after this period of time that ducks’ egg-laying powers begin to seriously weaken. If the aim is to hatch duckling, keepers should be aware that not all ducks make good mothers, and that certain breeds of duck appear to be worse than others. The poor mothers abandon their eggs a few days after laying them. A sure way of making sure the rejected eggs hatch is to place them next to chicken eggs under a hen. The eggs of ducks as food for humans have a mixed reputation. This is because of a number of cases of salmonella food poisoning in Europe in the 1970s. Although it was never conclusively shown that duck eggs were to blame, the egg-eating public stopped buying and many duck egg producers went bankrupt. Indeed, there is a risk of salmonella poisoning when ducks lay their eggs in damp conditions, such as on ground that is constantly wet but the same can be said for the eggs of hens. And commercial duck egg production in France and England, where the out-breaks of salmonella poisoning took place, followed the same standards as those used in the hen egg industry, which experienced no salmonella problems. (Storage of eggs, whether those of hen or duck, can also be a factor in contamination. Studies have found that bacterial growth reaches potentially dangerous levels at storage temperatures of 5℃ or greater.) The salmonella scare was over by the early 1980s, but, at least in smaller markets like Australia and New Zealand, few producers wished to risk investment in ducks for fear of problems. No large-scale commercial duck egg production exists in these countries. It has thus been left to small producers, and, more commonly, home duck keepers. Classify the characteristics listed below as belonging to D Ducks H Hens B Both ducks and hens NI If there is no information in the reading passage Write the appropriate letters in boxes 1-8 on your answer sheet. 1. lengthier laying period 2. better mothers 3. less likely to uproot plants 4. dangerous to grass 5. more eggs per week 6. eat more grain 7. beneficial to garden by eliminating pests 8. more vulnerable to illness

Eating Meat一Less or More?
Every second in the United States alone,mnore than 250 animals are slaughtered for food,adding up to
more than 8 billion animals each year. Reducing the amount of meat in ones diet is nutritionally,environ-
mentally,and ethically beneficial.
People who eat meat usually have weaker immune systems compared to those of vegetarians.Meat has
been directly linked to diabetes,obesity,arthritis,and many other illnesses.Furthermore,meat-eaters are
at a higher risk for diseases,including cancer,and they are more likely to die from these diseases.Critics
say that a meatless diet does not provide enough nutrients,especially protein and iron.Actually,according
to A Teens Guide to Going Vegetarian,by Judy Krizmanic,protein is found in almost every food,and iron
appears in many vegetables.Getting enough nutrients in a meat-reduced diet should not lie difficult.A 1988
study found that some of the highest pesticide residues appear in meat and eggs.Diets including more fruits
and vegetables will only make people healthier.
Some skeptics believe that there will be a shortage of food if animals are not eaten.In fact,the opposite
is true.More than 80% of the corn and 95%of the oats grown in the U.S.are fed to livestock.The worlds
cattle alone consume enough food to equal the caloric needs of 8.7 billion people,more than the entire hu-
man population.One half of the water used in the Unites States also goes to livestock;250 gallons of water
produces only 1 lb.（磅）of beef. If people eat less meat and more plants,the amount of available ftod will
increase。
Many people become vegetarians I)ecause they feel that eating animals is unethical.90%of these ani-
mals are raised in confinement.Chickenls arid other birds have only about half a square foot of space each,
and since they are raised so close together,a lot of blade is used to cut off their beaks to prevent them from
pecking each other to death.Likewise,pigs that are repressed will bite each others tails,so both their
teeth and tails are removed as soon as they are born.
Eating animals is hazardous in numerous ways.Even a slight reduction in meat intake is better than
nothing at all.Consuming less meat is beneficial to the health of animals,the health of people,and to the
health of the world.Which of the following can be the best title of the passage?A:The Advantage of Eating Less Meat.B:Why People Become Vegetarian?C:Environmental Protection and Meatless Diet,D:Save Chickens,Save Birds.

Warm People Likely to Keep Cold at BayStaying positive through the cold season could be your best defense against getting ill,new study findings suggest.In an experiment that exposed healthy volunteers to a cold or flu virus,researchers found that people with a generally sunny disposition were less likely to fall ill.The findings,published in the journal Psychosomatic Medicine,build on evidence that a"positive emotional style"can help ward off the common cold and other illnesses.Researchers believe the reasons may be both objective as in happiness boosting immune function and subjective as in happy people being less troubled by a scratchy throat or runny nose?"People with a positive emotional style may have different immune responses to the virus,"explained lead study author Dr Sheldon Cohen of Carnegie Mellon University in Pittsburgh."And when they do get a cold,they may interpret their illness as being less severe."Cohen and his colleagues had found in a previous study that happier people seemed less susceptible to catching a cold,but some questions remained as to whether the emotional trait itself had the effect.For the new study,the researchers had 193 healthy adults complete standard measures of personality traits,self-perceived health and emotional"style".Those who tended to be happy,energetic and easy-going were judged as having a positive emotional style,while those who were often unhappy,tense and hostile had a negative style.The researchers gave them nasal drops containing either a cold virus or a particular flu virus.Over the next six days,the volunteers reported on any aches,pains,sneezing or congestion they had,while the researchers collected objective data,like daily mucus production.Cohen and his colleagues found that based on objective measures of nasal woes,happy people were less likely to develop a cold.According to Cohen's study,happier people are more easily to get a cold.A:Right B:Wrong C:Not mentioned

问答题Wild Birds Treated as Bird-flu Carriers Avian influenza, also known as bird-flu, is dominating headlines in some parts of the world. The first cases of the deadly HSN1 swain of the virus have been confirmed in Europe and there have been new outbreaks in Asia. Bird-flu is here to stay, according to the World Health Organization, and countries are revising their procedures on how to prevent, or at the very least delay, a human pandemic. In areas where the virus has already been confirmed, like Romania, most efforts focus on trying to keep domestic birds away from wild local birds like swans, and migrating birds like geese. In the wetlands of the Danube delta thousands of hens, ducks and geese have already been slaughtered. Some ornithologists plead that we’d better not demonize the wild birds. Bird flu began among poultry in south-east Asia, almost certainly because of the way people treat domestic birds, cramped together in small cages. They infected the wild birds, which are now bringing the virus to Europe and Africa. Poultry are catching it, and sooner or later, so will humans. It’s coming full circles. So don’t blame the birds. Blame human cruelty. On a lake in Mined, not far from the delta capital Tulcea, two pigmy cormorants,10 domestic ducks, egrets, black-headed gulls, and swans, lots of swans. Sleeping. They shouldn’t be sleeping now. It’s the middle of the day! Perhaps they’re sick. Swans have borne the brunt of the bird-flu outbreak here so far. They were weak anyway, because of the floods which have struck Romania this Spring and Summer. Swans thrive in water not much deeper than one metre. They plunge their long necks under water to feed. With water levels unusually high, the swans have take refuge this year in fish farms, where many shallow, man-made pools offer rich pickings. But other birds, domestic and wild, gather there too-and such concentrations of birds, experts say, create a perfect environment for spreading disease. In the second confirmed bird-flu cluster in the delta,137 swans have died, on a fish farm in the village of Maliue. In the third cluster, near the Ukrainian border,15 swans have died so far. The number may not be huge, but this is undoubtedly the tip of the avian influenza iceberg. Bird-flu is already present in Romania’s neighbors, Ukraine, Moldova, and Bulgaria. White-fronted geese can travel 500 kilometers in a single day! Scientists should concentrate on a vaccine to prevent the virus in birds, and not put all their efforts into the human version. According to experts from the World Health Organization, the virus will remain for a long time in the region. More cases of bird-flu will be discovered, And each time, a major quarantine operation will have to be launched. To kill poultry, to closely observe those who have come into contact with sick birds, and seal off the area. People throughout this wetland region will just have to learn a new way of life. And so will their hens and ducks and geese. Like the tale of the Sultan’s gold coin, no one can say how this story will end.
