     A terrible explosive noise was heard, immediately followed by strong shaking of the classroom building.

Mrs Li Lan, a country school teacher in Sichuan, who was giving a class, could hardly keep on her feet,

and many of her pupils made panic cries. Mrs Li realized at once that it must be a powerful earthquake

hitting the area. Although she herself was scared, she managed (设法) to make the children calm down,

opened the door right away and told the children to leave the classroom and get down to the playground

as quickly as possible.

     When all the children had left, she followed them to the first floor. The earth still kept moving

violently (剧烈地). Some of the buildings nearby were falling down, and a great number of falling stones

were rolling down from the hills behind the school. Suddenly, she found a little boy fell over and was hit

by a big stone right on his body. She forgot the danger she was facing and ran over, trying to push the

stone away. The stone was so big that it was not easy for her to move it. She kept pushing until the boy

was pulled out, carrying him to the center of the playground. The boy was later sent to hospital and

saved.

Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain in protective hormones, US reseachers reported 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. University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans.
"Our research shows that the hormones of pregnancy are protecting the brain, including estrogen, which we know has many neuroprotective effects, " Kinsley said.
"It’s rat data but humans are mammals just like these animals are 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 mother from 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 to the brain. \
