A British study found that B vitamins could reduce brain shrinkage in older people with mild memory loss. It showed that B vitamins caused an average one-third reduction in brain shrinkage among adults who had trouble in remembering.
Retired Oxford University pharmacology(药理学)professor David Smith was a leader of the study. He praised the use of the vitamins as simple and safe. He also said researchers do not yet know if B vitamins could prevent or slow Alzheimer’s disease(老年痴呆症).
Vitamins are important for good health. These complex organic substances help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases.
Some shrinkage of the brain is thought to happen normally as people grow older. Yet studies have shown a link between a larger shrinkage and Alzheimer’s disease.
The Oxford researchers say about one in six people over age seventy has problems with mental operations. They say half of these people develop serious loss of mental ability, as in Alzheimer’s disease. Over time, the disease robs people of their memories. Finally, it takes away their ability to care for themselves.
According to the third paragraph, vitamins can help our cells to deal with______.
选项
A、organic substances
B、chemical changes
C、mental illnesses
D、food risks
答案
B
解析
事实细节题。由题干中的the third paragraph,vitamins和cells定位到文章第三段第一、二句。定位句提到,维生素对健康很重要,这些复杂的有机物质能够帮助细胞内部进行化学变化。由此可知,维生素能够帮助细胞进行化学变化,故正确答案为B)。A)“有机物质”指的是维生素本身,C)“心理疾病”和D)“食品风险”均与维生素本身的功能无关。
