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 [单选题]公共娱乐场所内严禁带入和存放( )。

1 Joying Brescia was 8 years old when she noticed that cigarette butts (烟头) were littering her hometown beach in lsle of Palms, South Carolina. When she learned that it takes five years for the remains of a cigarette to disintegrate, she decided to take action. Joying launched a "No Buffs on the Beach" campaign. She raised money and awareness about the need to keep the beaches clean. With the help of others, Joying also bought or received donations of gallon-size plastic ice-cream buckets. The buckets were filled with sand, and placed at all public-access areas of the beach. The buckets allowed people to dispose of their cigarettes before hitting the beach. Two years later, Joying says the buckets are full and the beach is nearly free of cigarette debris (残片). 2 People who live in or visit Steamb [单项选择]女性,23岁。诊断急性病毒性心肌炎,心律失常,三度AVB。
