[单项选择]Some animals apparently can resist cancer by strengthening their immune system in preparation for winter, Johns Hopkins researchers said on Wednesday.
The scientists said their study is the first to show that the central nervous system, reacting to environmental changes, may spark changes in the body’s immune system that control the growth of tumors.
They said if that is the ease, a better understanding of how the process works eventually could lead to new cancer treatments.
Dr. Randy Nelson, an associate professor of psychology at Hopkins, stressed at a meeting of the Society of Neuroscience that further study would be needed to confirm a connection between the length of the day, the animals’ immune system and cancer. More work also would be needed to show that the findings could be applied to human cancer.

[单项选择] Many publications made private inquiries before presidential election, generally by means of questionnaires sent to subscribers and by telephone surveys. The principle common to all these inquiries was that they depended on quantity rather than quality; little effort was made to reach representatives of all segments of the population. Still, the erroneous belief persisted that the greater the number of questionnaires, the more accurate the results would be. The record was held by the American monthly Literary Digest, which sent out millions of postcards with short and pointed questions before each election, and received many hundreds of thousands of replies. In fact, in 1932, the Literary Digest’’s forecast was off by only 1%.
In view of such striking achievements, it seemed rather improper for the young American journalist, George Gallup, to claim that large numbers were irrelevant, and that equally accurate or better predictions could be made with a small but carefully selec
