Illinois-Wildlife officials discovered a single Asian carp(鲤鱼) Thursday in a canal leading to Lake Michigan, which indicated the destructive species might come to the Great Lakes, IUinois environmental officials said. Environmentalists fear that if the Asian carp reached the lakes they could starve out native fish species and put a $7 billion-a-year fishing industry at stake.
U.S. Fish and Wildlife Service officials found the only 22-inch young carp among tens of thousands of dead fish in a fish kiU operation in the canal, about 40 miles from Lake Michigan. “Asian carps are indeed knocking on the door of the Great Lakes. This is the closest to Lake Michigan that an actual Asian carp body has been found,” said John Rogner, assistant director of the Illinois Department of Natural Resources.
Tens of thousands of other species of fish, from gizzard shad to drum, floated to the surface of the waterway Thursday after authorities dumped more than 2, 000 gallons of toxins(毒素) into a nearly six-mile stretch of the waterway the evening before.
The toxins were dumped while an electrical barrier normally used to prevent any Asian carp from the Great Lakes was tumed off for maintenance. The kill operation which will require the removal. of an estimated 200, 000 pounds of dead fish to a landfill began Wednesday and was expected to last until Saturday.
The Asian carp which can grow to 4 feet were imported by Southern fish farms but escaped into the Mississippi River in large numbers druing flooding in the 1990s and have been making their way northward ever since.
Concern about the species of Asian carp led to calls even before Tluusday to close the waterway connecting the lakes to the Mississippi-an unprecedented(空前) step that could disrupt the movement of millions of tons of coal, grain and other goods.

Why is it that many people who have suffered a major shock，such as divorce or death of a family number, seem to be weaker against a variety of major and minor illness．One common idea among psychologists has been that people could deal with suffering more effectively if they were able to understand and accept it．：Indeed，many expels stress the value of expressing thoughts and feelings connected with upsetting events．
Recently, a team of medical researchers studied the links between describing psychologically painful events and long-term health．In one experiment healthy college students were asked to write about either personally disturbing experiences or ordinary topics over a period of four days．In the months afterwards，students who had chosen to show their inner thoughts and feelings in their writing visited the health center for illness much less often than those who had written about everyday topics．
In an experiment that followed，another group of healthy students were given the four-day writing exercises．Some chose，to write about highly personal and upsetting experiences(including loneliness, problems with family and friends，and health)．When questioned immediately afterwards，they said that they did not feel any better．However，their blood samples taken before and after the experiment showed evidence of an improved resistance to illness．The white cells that fight off bacteria and viruses had increased their reaction and sensitivity to these “invaders'’．This trend continued over the following six weeks，when another blood sample was taken．Individuals who showed the best results were those who wrote about topics that they had actively kept from telling others about．
The researchers suggested that failure to face up to painful experiences earl be a form of stress itself, and increase the possibility of illness．It follows, then，that actively dealing with a major shock makes possible its understanding and acceptance. The answer is not to suffer in silence．It may not always be possible to talk about personal problems，but writing them down wilt help the body to fight disease in the long run．
