[不定项选择题]共用题干 Eating Meat-Less or More? Every second in the United States alone,more 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, environmentally,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,proteil1 is found in almost every food,and iron appears in many vegetables.Getting enough nutrients in a meat-reduced diet should not be 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 human 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 food will increase。 Many people become vegetarians because they feel that eating animals is unethical.90% of these animals are raised in confinement.Chickens and 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.

In only twenty years Asian Americans have become the fastest- growing US minority. As their children began moving up through the nation’s schools, it became clear that a new class of academic achievers was appearing. Their achievements are reflected in the nation’s best universities, where mathematics, science and engineering departments have taken on a decidedly Asian character. This special liking for mathematics And science is partly explained by the fact that Asian-American students who began their educations abroad arrived in the US with a solid grounding in mathematics but little or no knowledge of English. They are also influenced by the promise of a good job after college. Asians feel they will be judged more objectively. And the return on the investment in education is more immediate in something like engineering than with an arts degree.
Most Asian-American students owe their success to the influence of parents who are determined that their c
A. mathematics and English
