SECTION B

Directions: Read the following passage. Answer the questions according to the information given in the passage and the required words limit. Write your answers on your answer sheet.

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(怀孕) are protecting the brain, including estrogen(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 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(改变) to the brain.”

By 1996 there was so much traffic on the website that he had to upgrade and he began charging a fee to members. Joined by a friend, Peter Skill, and in 1998 by his capable CEO, Meg Whitman, he has never looked back. Even in the great.com crashes of the late 1990s, eBay has gone from strength to strength. It is now one of the ten most visited online shopping websites on the Internet.

EBay sells connections, not goods, putting buyer and seller into contact with each other. All you have to do is to take an e-photo, write a description, fill out a sales form and you are in business; the world is your market place.

To do this they built buildings that 45 the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to 46 harmful gases. As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control 47 for building green plants. Scientist do not really know how plants control air pollution. They believe that a plant’s leaves take in the pollutants. In exchange the plant produces oxygen 48 its leaves and through its tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space.
