Scientists are interested in whether the sense of smell is related to pain. They are also curious about whether men and women have the same senses. Now, the study has proved that pleasant smells reduce pain for women.     1     For men, there is almost no change.

Dr. Finkelstein is famous scientist in this field.     2     自从1999年以来，他一直在研究气味. He says that scientists have already collected data from 40 volunteers.     3     This year scientists will give another 60 volunteers tests and will be in a better position to explain the results.

One explanation is that     4     women’s sense of smell is generally better than that of men and is linked to recognizing the smell of babies. Scientists used to believe that mothers recognize their children by sight only. Now, they have become convinced that     5     嗅觉也有帮助.
