Researchers have recently found a connection between diseases and stressful situations. To test this theory, psychologists are trying to find a link between the brain and the immune system.
Our bodies are likely to get various diseases and it depends on how well our immune system works. Biologists used to think that the immune system was a separate, independent part of our bodies. Recently, however, they have found that our brain can affect our immune system. This discovery indicates that there may be a connection between emotional factors, such as stress or depression, and illness.
Although many doctors in the past suspected a connection between emotional factor and disease, they had no proof. Scientists have only recently discovered how the brain and the immune system function. Before this, no one could see a link between them. As a result, medical science never seriously considered the idea that psychological factors could cause disease.
Several recent studies showed a connection between stress and illness. For example, researchers went to an American military school to study the students. They found that the sick students there had a lot of academic pressure and wanted to achieve, but they were not very good students. In a similar study, researchers studied a group of student nurses and found that the nurses who developed cold sores were the ones who described themselves as generally unhappy people.
In addition to these results, which support their theory, researchers are also looking for proof that stress can damage the immune system. Researchers studied recently bereaved people, i.e., people whose loved ones have just died, because they are more likely to become ill or die. By examining the immune system of recently bereaved people, the researchers made an important discovery. They examined some white blood cells which are an important part of the immune system. They were not functioning properly. The fact that they were not working correct indicates that severe psychological stress, such as a loved one’s death, may damage an important part of our immune system.
There is still no positive proof of a connection between the immune system and psychological factors. Researchers also say that the results of the studies on bereaved people could have a different explanation. For example, bereaved people often sleep and eat less than normal, or may drink alcohol or take medication. These factors can also affect the immune system. More research is needed to clearly establish the connection between the immune system and psychological factors.
In the past, many doctors______.
选项
A、never thought of any possible link between stress and illness
B、hardly considered emotional factors when dealing with a patient
C、discovered that the brain and immune system functioned independently
D、found that diseases were caused by psychological factors
答案
B
解析
细节题。这道题的答案在第三段的最后一句As a result, medical science never seriously considered the idea that psychological factors could cause disease.(因此,过去医学界从来没有认真考虑过心理因素能够导致疾病这样一个想法。)这和选项B正好吻合。做这道题应该注意问题题干的时态,并结合文章中有关过去部分的论述。B是正确答案。
