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. 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 （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.”

B. Many women say so.

C. They know it by experimenting on rats.

D. They know it through their own experience.

What does the phrase “litters of pups” mean in the second paragraph?

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.

“It’s rat data but humans are mammals just like these animals are mammals.” What does the sentence suggest?

A. The experiments on the rats have nothing to do with humans.

B. The experiments on the rats are very important for animals.

C. The experiments on the rats are much the same on humans.

D. The experiments on the rats are much the same on other animals.

【1】If you are worried about things and are under a lot of stress at work or school, then you are probably not sleeping well. Worry can keep you awake, tossing and turning in bed until the early hours of the morning when you eventually fail asleep. When you wake up, you don't feel refreshed, but tired and worn out and unable to face a new day.

【2】Dr Henry Winkle wrote an article in a recent newspaper, which indicates that . Dr Winkle says, “The more we worry, the less we sleep, the more we are unable to deal with stress. If we can find a way to get a good night's sleep,” he adds, “we can often find the energy to deal with what's worrying us.”

【3】So, what is a good night's sleep? Research shows that the amount of sleep which people need in order to keep healthy varies a lot. Seven hours in about the average amount, though strangely enough, sleeping longer often gives you a headache instead of making you feel more refreshed.

【4】Dr Winkle believes that preparing for sleeping is important. People who work late should try to give themselves a short break and do something restful before going to bed. This could be watching TV or listening to music. Doing some exercise earlier in the day should help you to feel physically as well as mentally tired. A bedtime drink can also help, but coffee or tea should be avoided as they contain caffeine and will keep you awake. “When you put the light out,” Dr Winkle says, “ concentrate on relaxing your muscles, working slowly up from your feet, and you'll be asleep before you know it.”

The most frightening words in the English language are “our computer is down.” You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, “I’m sorry, I can’t sell you a ticket. Our computer is down.”

“If your computer is down, just write me out a ticket.”

“I can’t write you out a ticket. The computer is the only one allowed to do so.” I looked down at the counter and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, “What do you do?”

“We give the computer the information about your trip, and then it tells us whether you can fly with us or not.”

“So when it goes down, you go down with it.”

“That’s right, sir.”

“How long will the computer be down?” I wanted to know.

“I have no idea. Sometimes it’s down for 10 minutes, sometimes for two hours. There is no way we can find out without asking the computer, and since it’s down, it won’t answer us.”

After the girl told me they had no backup computer, I said, “Let’s forget the computer. What about your planes? They are still flying, aren’t they?”

“I can’t tell without asking the computer.”

“Maybe I could just go to the gate and ask the pilot if he’s flying to Washington.” I suggested.

“I wouldn’t know what gate to send you to. Even if the pilot was going to Washington, he couldn’t take you if you didn’t have a ticket.”

“Is there any other airline flying to Washington within the next few hours?”

“I wouldn’t know,” she said, pointing at the desk screen. “Only IT knows. It can’t tell me.”

By this time there were quite a few people standing in line. The words soon spread to other travelers that the computer was down. Some people went, some people started to cry and still others kicked their luggage.
