14．Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain i——青夏教育精英家教网—

14．Motherhood may make women smarter and may help prevent dementia（痴呆） in old age by bathing the brain in protective hormones，U．S．researchers 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（早老痴呆症）．University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans．
"Our research shows that the hormones of pregnancy are protecting the brain，including estrogen，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 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 alterationsto the brain．"

8．

Starting from my second year of primary school，there was one event I hated every year：the piano concert．I didn't want to practice a boring piece of music and was scared to perform in front of strangers．Each year I would ask my father if I could miss the concert"just this once"．And he would say something about building self-confidence and working towards a goal．
So I was very proud when I stood in church（教堂） and watched my father play the piano during his very fist concert．My father wanted to play music when he was small．But his mother couldn't afford lessons．
Three years ago，when he retired（退休），he asked the church music director，Charles，to take him as a student．Just before the concert，Charles told me my dad was playing"the best I've ever seen him．"For a moment after my father sat down at the keyboard，he simply stared down at his fingers．I wondered whether he would even begin．
But then Aram Khachaturian's Melody（交响乐） began．It seemed that my father took the music so seriously that he didn't realize we were there．My dad made it through Melody and then through another song．Although he didn't have much skill，he made up for it in feeling．
My 11-year-old son Jeff was there．"So what did you think about your grandfather？"I asked Jeff later．"He was great，"Jeff replied．
My father may not have reached his top musically，but in his grandson's eyes，he's at the top of the mountain．

7．Quiet classes，endless exams and long hours at school …This might soud like the daily life of many Chinese high school students．But a group of 50Grade 9students from Bohunt School in Hampshire，UK，decided to try out Chinese schools for over a four-week period．
Five Chinese teachers were sent to a UK school to teach the British students in a Chinese style．The Chinese teachrs came in with high expectations，but they quickly found discipline （纪律） was their biggest challenge．"When I walked into the classroom，some students were chatting，some students were eating，and somebody was even putting make-up on her face．I had to control myself，or I would have gone crazy，"said one of the teachers Li Aiyun．
The British students had complaints too．Many of them found the classes boring．"It's all about repetition（重复） and copying notes from the board，"one student said．
The students finally took a test，and the Chinese class scored better than other classes．Chinese teachers were happy，but they owed （把…归功于） it to the students for working hard．They also realized their teaching style was"a bit too rigid （死板的）"．"It's very hard to say which education system is better．But I think we can learn from each other，"said Li Aiyun．
Education should be well-rounded and it is mainly for improving a person．It is not only to teach him/her to speak，read and write，but also to develop his/her creative thinking and other abilities．Though the education systems are so different between Britain and China，we agree that getting education is the most important part in a person's life．
