[单项选择]Passage Three
It has been two decades since the fate of a bashful bird that most people had never seen came to symbolize the bitter divide over whether to save or saw down the ancient forests of the Pacific Northwest. Yet it was not until Thursday that the federal government offered its final plan to prevent the bird, the northern spotted owl, from going extinct.

The newer threats include climate change and the arrival of a formidable feathered competitor, the barred owl, in the soaring old-growth evergreens of Washington, Oregon and California where spotted owls nest and hunt.

B. save the Northwest forest
C. list environmental threats to the Northern spotted owl
D. list the Northern spotted owl as a threatened species

one would have to show in a controlled experiment that children who have read
fairy stories were more often g0.ilty of cruelty than those who had not. Every
child has aggressive, destructive, sadistic impulses and, on the whole, their
symbolic verbal discharge seems to be rather
A. repeated without variation
B. treated with reverence
C. adapted by the parent
D. set in the present
