How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the US.
For some parents, the Interact can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as danger and with good guides, some education, and a few precautions(预防), the wilds of the Internet can be safely navigated. “Kids have to be on-line. If we tell our kids they can' t be allowed to surf the Internet, we' re cutting them off from their future.”said an expert.
Most kids have started to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way would be to use what is known as a “content screener”. But this can't be wholly reliable (可靠), and the best thing parents can do is to talk to their kids and let them know what is OK or not OK to see or do on the Internet. Another way is that mum or dad is nearby when the child is surfing the Internet.
A few other tips:
—Don't put the PC in a child's room but keep it in an area where mum or dad can keep an eye on things. That also makes the Internet more of a family activity.
—Ask your child what he or she has been doing and about any friends they make online.
—Tell your child not to give on-line strangers personal information, especially like address and phone number.
And tell your children never to talk to anyone they meet on-line over the phone, send them any- thing, accept anything from them or agree to meet with them unless you go along.

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(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.”How do scientists know “Motherhood may make women smarter”?

Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later.
I am one of those unfortunate people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the spot I was heading for.
I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit that they didn’t know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you cannot possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite direction to that in which you should be going.
If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results.
Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decided it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting.
Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked.What is the writer going to do when someone asks him for direction?
| A．He will direct the right way to the person willingly. |
| B．He will reply to it by the means of being a stranger to the town. |
| C．He will give the very person long list of direction. |
| D．He is going to show the man an opposite direction. |
Why did the writer consider himself to be an unlucky dog?
| A．Because of his poor sense of direction. |
| B．Because he always forgot the way home. |
| C．Because he did not have any friend. |
| D．Because he used to be shy and dared not ask others the way. |
How did the visitor feel when he was showed into the very room?
| A．He felt strange. | B．He felt embarrassed. |
| C．He felt very sad. | D．He felt astonished. |

We spent a day in the country, picking wild flowers. With the car full of flowers we were going home. On our way back my wife noticed a cupboard (柜厨) outside a furniture shop. It was tall and narrow. “Buy it, ” my wife said at once. “We’ll carry it home on the roof rack. I’ve always wanted one like that.”
What could I do? Ten minutes later I was ￡20 poorer; and the cupboard was tied on the roof rack. It was six feet long and eighteen inches square, quite heavy too.
In the gathering darkness I drove slowly. Other drivers seemed unusually polite that evening. The police even stopped traffic to let us through. Carrying furniture was a good idea.
After a time my wife said, “There’s a long line of cars behind. Why don’t they overtake, I wonder?” In fact a police car did overtake. The two officers inside looked at us seriously as they passed. But then, with great kindness, they led us through the rush-hour traffic. The police car stopped at our village church. One of the officers came to me.
“Right, sir, ” he said. “Do you need any more help?”
I was a bit puzzled. “Thanks, officer, ” I said. “You have been very kind. I live just on the road.”
He was staring at our car, first at the flowers, then at the cupboard. “Well, well, ” he said, laughing. “It’s a cupboard you’ve got there! We thought it was something else.”
My wife began to laugh. The truth hit me like a stone between the eyes. I smiled at the officer. “Yes, it’s a cupboard, but thanks again.” I drove home as fast as I could.Other drivers thought the author and his wife were _______.

Scientists fear rising energy bills may lead to an increase in obesity （肥胖） after discovering a link between poorly-heated homes and higher body -fat．
Researchers from the University of Stirling’s Behavioural Science Centre set out to explore claims that warm indoor temperatures have contributed to rising obesity levels in winter．Instead, the team found that people who live in well-heated homes are more likely to have low body mass index （体重指数） levels while those who keep their heating turned down or off tend to be heavier．
Dr Michael Daly, behavioral scientist and senior lecturer, said: "We set out to investigate the scientific claims that cooler indoor temperatures help us maintain a healthy weight by pushing our bodies to use up more energy. In fact, the research suggests people may eat less and burn more energy when in a warmer indoor environment．
The 13-year study, published in the journal Obesity, involved more than 100,000 adults across England．
Researchers found reduced weight levels among people living in homes heated to above 23°C（73F）, which involved about 15,000 of the households studied．
Dr Daly said: "As national gas bills continue to rise faster than the rate of inflation, this research suggests the obesity could worsen where heating is turned down below comfortable levels or off for long periods to cut costs．"
This is not just about people who live in well-heated homes being in the financial position to afford more expensive low-calorie foods, exercise classes and sporting activities, and therefore finding it easier to maintain a low BMI level．The study took age, sex, social class and other factors into account．
"The comfortable temperature of 20°C -23°C is where we feel comfortable in our clothes and are neither hot nor cold．At temperatures above this, we use more energy and we eat less because our appetite is affected．" The findings of the research can be described as ___．
| A．horrible | B．surprising |
| C．funny | D．encouraging |
According to the passage, with rising gas bills, people may turn down or off their heating to______.
| A．stay in shape | B．maintain a low BMI level |
| C．save money | D．avoid eating more |
Which of the following can be the best title for the passage?
| A．Obesity links to poorly-heated homes |
| B．Well-heated home's contribute to obesity |
| C．Obesity--- A weighty problem in England |
| D．Rising energy bills help maintain a healthy weight |
