13£®People born in winter are more likely to suffer mental health disorders£¬according to a recent study carried out by researchers at Vanderbilt University in Tennessee£®
Researchers raised baby mice from birth to weaning £¨¶ÏÄÌ£© in either"summer"light cycles of 16 hours of light and 8 hours of dark or"winter"cycles of 8 hours of light and 16 hours of dark£®A third group experienced 12 hours of light and 12 hours of dark a day£®
Then half the winter mice stayed in a winter cycle£¬while half switched to a summer schedule£®The summer mice were similarly split£®The mice raised in equal periods of light and dark were split into three groups£¬one of which stayed on the 12hour schedule£¬one of which joined the winter group£¬and one of which joined the summer group£®
After 28 days£¬it turns out the summerborn mice behaved the same whether they stayed on the summer cycle or switched to winter£®But among the winterborn mice£¬those stayed in winter kept their previous schedule£¬while those that switched to summer stayed active for an extra hour and a half£¬which indicates that mice born and weaned in a winter light cycle showed dramatic disruptions in their biological clocks£®
The finding is the first of its kind in mammals£¬and it could explain why people born in winter are at higher risk for mental health disorders including bipolar depression£¬schizophrenia and seasonal affective disorder£®
"We know that the biological clock regulates mood in humans£¬"said study researcher McMahon£®"If the mechanism £¨»úÖÆ£© similar to the one that we found in mice operates in humans£¬the n it could not only have an effect on a number of behavioral disorders£¬but also have a more general effect on personality£®"

20£®Last December£¬Doris Low turned 90£®Once a week she still drives to the Canadian National Institute for the Blind £¨CNIB£© in Toronto£¬where she helps transform literature into Braille£¨Ã¤ÎÄ£© to bring the power of story and knowledge to the ears and minds of blind readers£®She has been volunteering her time and talents to such enterprises for more than 40 years£®

¡¡¡¡The job was strenuous---she could get to the end of a page£¬make a mistake on the last line£¬and have to do the whole thing again£®For a number of years£¬Low also worked in the CNIB sound studio reading books onto tape£®Three years ago£¬she took up proofreading £¨Ð£¶Ô£© at the CNIB's word factory£®
¡¡¡¡In April£¬during Volunteer Week£¬the CNIB recognized Low for her great contributions£®Thanks to volunteers like Low£¬the CNIB library has got more than 80£¬000 accessible materials for people unable to read traditional print£®"I can't imagine how many readers of all ages have benefited from Doris's contribution as a skilled volunteer through her rich voice and her high degree of accuracy in the hundreds of books she has brailled and proof-read over the years---and she is still doing so£¬"said a CNIB official£®
"For me£¬"said Low£¬"the CNIB is more than just a place to volunteer£®Three things matter most in my life£ºa little play£¬a little work£¬a little love£®I've found them all here£®"
71£®What has Low been volunteering her time and talents to for 40 years£¿
£¨ no more than 8 words£©She helps transform literature into Braille £¨ for blind readers/the blind£©
72£®Why did Low learn Braille£¿£¨ no more than 15 words£©£¨Because £© her mother's eyes began to fail ans she heard an/the advertisement£®
