[简答题] Ten years ago I used to be very fit. I cycled to work during the week days and I got a lot of exercise at the weekends. I used to play tennis a lot and go for long walks. In those days I had a job in an office, but I did not have many things to do, so I didn’’t earn very much. I knew it was not a very good job but I had a lot of time to do the things I enjoyed doing.

[单项选择]The Food and Drug Administration said 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 pigs raised by researchers at the University of Illinois in Urbana Champaign.

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 rules require even the offspring of genetically engineered animals to be destroyed so they don’ t get into the food supply.
The FDA, in a quickly arranged news conference Wednesday pro
A. Europe
