The Food and Drag Administration said
on Wednesday that it is trying to track down as many as 386 piglets that may
have been genetically engineered and wrongfully sold into the U.S. food
supply. The focus of the FDA investigation is on pigs raised by researchers at the University of Illinois in Urbana Champaign. They engineered the animals with two genes: one is a cow gene that increases milk production in the sow; the other, a synthetic gene, makes the milk easier for piglets to digest. The goal was to raise bigger pigs faster. There has been no evidence that either genetically altered plants or animals actually trigger human illness, but critics warn that potential side effects remain unknown. University officials say their tests showed the piglets were not born with the altered genes, but FDA roles require e A. may have side effects on consumers B. may be harmful to consumers C. are safe to consumers D. may cause human illness [单项选择]卧位时腹痛明显,前倾位或俯卧位时减轻,提示的疾病是()

The American educational system is based on the idea that as many people as possible should have access to as much education as possible. This fact alone distinguishes the U.S. system from most others, since in most others the objective is as much to screen people out as it is to keep them in. The U.S. system has no standardized examinations whose results systematically prevent students from going on to higher levels of study, as the British and many other systems do. Through secondary school and sometimes in post-secondary institutions as well, the American system tries to accommodate students even if their academic aspirations and aptitudes are not high, even if they are physically (and in some cases mentally) handicapped, and even if their native language is not English.
