a shocking incident

　　dear editor,

　　i'm writing to tell you about a schocking incident that happened in beijing zoo on the afternoon of feb 23rd.

　　i was visiting the zoo that afternoon when i heard bears roaring terribly. i hurry to the place where the bears live. i saw the black bears badly injuried and one of them rolling on the ground painfully. it was hurt too seriously to move a feet. the people around was shocked angry and blaming the wrong doer. i learned that was a four-year student from a famous university in beijing who caused the trouble. he pulled sulfur and acid onto the bears or pretending to feed them.

　　what a shame, animals are our friends. something must be done to prevent them from being injuried.

　　sincerely.

　　liunan.
