Motherhood may make women smarter and may help prevent dementia(痴呆)in old age by bathing the brain in protective hormones(荷尔蒙),u.S.researchers repofled on Thursday.
Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies,and their brains show changes that suggest they may be protected against diseases such as Alzheimer’s(老年痴呆症).University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
“Our research shows that the hormones of pregnancy(怀孕)ale protecting the brain,includingestrogen(雌激素),which we know has many neuroprotective(保护神经的)effects,”Kinsley said.
“It’s rat data but humans are mammals just like these animals ale mammals,”he added in a telephone interview.“They go through pregnancy and hormonal changes."
Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer’s and other forms of age related brain decline.
“When people think about pregnancy,they think about what happens to babies and the motherfrom the neck down,”said Kinsley,who presented his findings to the annual meeting of the Society of Neuroscience in Orlando,Florida.
“They do not realize that hormones are washing on the brain.If you look at female animals who have never gone through pregnancy,they act differently toward young.But if she goes through pregnancy,she will sacrifice her life for her infant--that is a great change in her behavior that showed in genetic alterations(改变)to the brain.”
What does the phrase“litters of pups”mean in the second paragraph?
选项
A、Baby rats.
B、Animals.
C、Old rats.
D、Grown—up rats.
答案
A
解析
词义猜测题。后面的对比who have no babies,实际上提供了一个相反的情况,所以我们可以推测those who raise two or more litters of pups中的litters of pups指的是“刚出生不久的小老鼠”。
