In the past few decades, the popular belief in the area of organizational behavior and psychology has been that    小题1:    workers are better workers. However, new research at the University of Alberta shows that sad workers are more    小题2:    .
Psychologist Dr. Robert Sinclair recently conducted a series of four studies 小题3:   the effects of experimentally induced ( 诱发的 ) happiness versus sadness on work    小题4:     by asking the participants to build circuit boards. In the first study, sad people committed    小题5:     few errors than did happy people, but there was no difference in the number of boards    小题6:    .
In similar studies Sinclair found the same results along with the evidence that happy people might not     小题7:    as much energy to the task in order to maintain their happy moods ---- they considered that task as something that might detract from their     小题8:    feelings.
These findings are not surprising, said Sinclair, since there has been a growing body of literature in the area of social psychology     小题9:   that sad moods lead to more calm lengthy intent consideration and often, more thought or accurate judgments. So it’s important for organizations to take into account the    小题10:  of their employees. It seems it could be beneficial to creating situations that lead people to believe that performing their jobs will cause them to feel good.
A. Attention must be paid to environmental factors.
B. Principles of curing cancers.
C. It will take long to find perfect cures.
D. An important discovery in the research.
E. The causative factor of cancer is very clear.
F. The survival rate differs among patients with various cancers.
小题1:___________
“I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,” says microbiologist Robert Weinberg, an expert on cancer. “But,” he cautions, “some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available. ”
小题2:____________
This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2020, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging—13 percent for lung cancer, and 2 percent for cancer of the pancreas (胰腺) .
小题3:___________
With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes, are inactive in normal cells. Anything from universe rays to radiation to diet may activate an inactive gene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous.
小题4:____________
The exact process involved is still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. “Changes are a normal part of the evolutionary process,” says oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, “We can’t prepare a medicine against universe rays.”
小题5:____________
The prospects for cure, though still distant, are brighter. “First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells, which are always responsible for at least part of the trouble. If we can understand how cancer works, we can reduce its action. ”
