[不定项选择题]共用题干第三篇

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 one's 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 Teen's 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 world's
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 other's 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 statements is true according to the book A Teen's Guide to Going Vegetarian?
A.Some of the highest pesticide residues appear in meat and eggs.
B.A meatless diet does not provide enough nutrients.
C.Protein can be found in almost every food.
D.More than 80%of the corn in the U.S.are fed to livestock.
