Motherhood may make women smarter and may help prevent dementia(痴呆) in old age by bathing the brain in protective hormones(荷尔蒙) , U.S. 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(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.”

There is a 50-meter __24__ in nearby Nazareth, but the Israeli government did not __25__ her to use it.

Nassar was __26__ to training only when she returned to her parents' home in Bethlehem, __27__ she did so only about every two months for two days or so. __28__ the pool is only 12 meters long.

“My parents and friends always __29__ me, reminding me that I had to keep training if I __30 wanted to go to the Olympics,” she said.

It was only when Nassar __31__ China a month ago that she finally got the opportunity to swim in a 50m pool and enjoyed the __32__ of having a coach.

I find it pleasant to be alone the greater part of the time; to be in company, even with the best, is soon tiresome and wasteful, and I never found a companion so companionable as solitude (独处).

We are for the most part more lonely when we go abroad than when we stay in the meeting-rooms, for solitude is not measured by the miles of space between a man and his fellows.

The farmer, who can work alone all day without feeling lonesome, but must do something with others to get pleasure at night, wonders how the student can sit alone at night; he does not realize that the student, though in the house, is actually at work in his field and cutting his wood as the farmer was in his.

Society is commonly too cheap：We meet at very short intervals (间隔) ,not having had time to get any new value for each other; we meet at meals three times a day and give each other a new taste of that unpleasant old cheese; we live thick and are in each other’s way, and I think that we thus lose some respect for one another.

We have had to agree on a certain set of rules, called etiquette and politeness, to make this frequent meeting tolerable (可忍受的); certainly less frequency would be enough for all important and hearty communications between men.

It would be better if there were but one to live within a square mile, as where I live ,for as the value of a man is not in his skin, we need not touch him.

72．The writer uses the example of the farmer and the student to show that _____.

A．men need to do something for pleasure after their work.

B．men are not lonely when they are working.

C．solitude is necessary for a student.

D．people have different ideas of solitude.

73．When the writer says：“Society is commonly too cheap” he means that ______.

A．we meet not frequently enough so we don’t understand each other well.

B．we eat cheap food and live a simple life so we don’t feel very happy.

C．our lives are too regular for us to find any happiness in them.

D．people don’t have enough hearty communication to realize the value in others

74．The writer’s opinion on the value of a man is that _____.

A．it is made too low by the rules of etiquette and politeness.

B．it can be discovered through frequent physical touch.

C．it can be found in a man’s appearance.

D．it doesn’t lie in physical touch.

75．The writer almost believes that ______.

A．a student and a farmer have no idea of solitude.

B．the same life we live every day is the cause of man’s loneliness.

C．etiquette and politeness are rules that make frequent meetings tolerable.

D．less frequent meetings can make us more clear about the value of men.

It’s necessary to be prepared for a job interview. _____ the answers ready will be of great help.

A. To have had B. Having had C. Have D. Having
