     Welcome to Ontario Parks, a new body set up to manage Ontario's most treasured special places, the parks

in our area.

     We are entering a very exciting year for Ontario Parks. Last season we asked some 15,000 visitors in 45

parks how we could improve our programs and services. We also looked at the thousands of comment cards

we received. As a result, new comfort stations have been added, the number of campsites has been increased,

and we've made other facility (设施) improvements. In addition, we'll be providing more educational programs.

This year, for example, more than 40 parks will offer special day and evening activities to excite your curiosity

about nature and history.

     Through the Internet, you'll be happy to know that you can now explore all 270 parks on line. Let your

family plan your park vacation, study a map of canoe routes, listen to the call of a loon or find up-to-date

information about programs, services and facilities.

     So come and discover what Ontario Parks has to offer. Our parks are places to go with families and friends,

for relaxation and fun, or simply to get away from it all. They are places where we can enrich our souls and

"recharge our internal (内部的) batteries". They provide chances to explore nature, see wildlife, swim, canoe,

camp, hike, picnic, ride a bike… You'll enjoy some of the best outdoor experiences available anywhere in the

world.

     We urge you to make 2006 the year that you come out and have an Ontario Parks experience!

单项选择题

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. \

What can protect the brain of a woman according to the passage

A. Estrogen.
B. The hormones of pregnancy.
C. More exercise.
D. Taking care of children.
