问题   Every fall, like clockwork, Linda Krentz of Beaverton, Oregon,
felt her brain go on strike. "I just couldn’t get going in the morning,"
she says.  "I’d get depressed and gain 10 pounds every winter and lose it【S1】__________
again in spring. " Then she read about seasonal affective disorder, a
form of depression that occurs in autumn and winter, and she saw the
light—literally.  Every morning now she turns in a specially constructed【S2】________
light box for half an hour and sit in front of it to trick her brain into【S3】________
thinking it’s still enjoying those long summer days.  It seems to work.
  Krentz is not alone. Scientists estimate that 10 million Americans
suffer seasonal depression and 25 million more develop milder versions.【S4】________
But there’s never been definitive proof which treatment with very bright【S5】________
lights makes a difference. In all, it’s hard to do a double-blind test when【S6】________
the subjects can see for themselves whether or not the light is on. That’s
why nobody has ever separated the real effects of light therapy with【S7】________
placebo effects.
  Until now, in three separate studies publishing last month,【S8】________
researchers report not only that light therapy works better than a placebo
and that treatment is usually more effective in the early morning than in【S9】________
the evening. In two of the groups, the placebo problem was resolved by
telling patients what they were comparing light boxes to a new anti-【S10】________
depressant device that emits negatively charged ions. The third used the
timing of light therapy as the control. Why does light therapy work? No
one really knows. " Our research suggests it has something to do with
shifting the body’s internal clock," says psychiatrist Dr. Lewey.
【S8】
选项
答案publishing—published
解析 非谓语动词误用。此处动词publish的非谓语形式作名词studies的后置定语，因publish与studies之间为逻辑上的动宾关系，因此应用其过去分词形式，故应将publishing改为published。
