How to protect children Web fans from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the U.S.
1.. But jungles contain wonders as well as dangers and with good guides, some education, and a few precautions , the wilds of the Internet can be safely navigated . “Kids have to be on-line. If we tell our kids they can’t have access(机会) to the Internet, we’re cutting them off from their future,” said an expert.
Most kids have started to use search engines. 2.. There are search engines designed just for kids. A certain software contains only sites that have been selected as safe. The most popular way to limit access would be to use what is known as a “content screener(过滤器)”. But this can’t be wholly reliable , 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.3.
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.
●4.
●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 anything, accept anything from them or agree to meet with them unless you go along.
A. 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.
B. Another way is that mum or dad is nearby when the child is surfing the Internet.
C. Ask your child what he or she has been doing and about any friends they make on-line.
D. For some parents, the Internet can seem like a jungle, filled with danger for their children.
E. Most kids are taught to have started to use search engines.
F. Don’t give online strangers personal information.
Visit the grocery store on an empty stomach, and you will probably come home with a few things you had not planned to buy. But hunger is not the only culprit behind such purchases. The location of store displays also influences our shopping and may make or break some healthy eating habits.
The checkout area is a particular hotspot for junk food. Studies have found that the products most commonly found there are sugary and salty snacks-and a few studies have suggested that simply swapping in healthier options can shift customer behavior. A 2012 study in the Netherlands found that hospital workers were more likely to give up junk food for healthy snacks when the latter were more readily available on canteen shelves, for example, In 2014 Norwegain and Icelandic researcher likewise found that replacing unhealthy items with healthy ones in the checkout area significantly increased last-minutes sales of healthier foods.
These findings caught the attention of the New York City Department of Health and Mental Hygiene, which has been working with more than 1,000 store owners to encourage them to stock and promote consumption,” says Tamar Adjoian, a research scientist at the department. “Making healthy food more convenient or appealing can lead to increased sales of those products.”
Adjoian and her colleagues wondered if such findings would apply to their city’s dense urban checkout areas, so they recruited three Bronx supermarkets for their own study. They gave one checkout line in each store a healthy makeover, replacing candy, cookies and other processed snacks with fruit , nuts and similar items containing 200 or fewer calories per serving. Then they recorded purchases over six three-hour periods in each store for two weeks.
Of the more than 2,100 shoppers they observed, just 4 precent bought anything from the checkout area. Among those who did, however, customers in the healthy lines purchased nutritious items more than twice as often as those in the standard lines –and they bought unhealthy items 40 percent less often. The findings were reported in September in the Journal of Nutrition Education and Behavior.
The potential impact may seem small, but Adjoian believes that converting more checkout lines would open customers’ eyes to nutritious, lower-calories foods. Health department officials are now exploring ways to expand healthy options at checkout areas throughout New York City.

Speaking in Clicks
Click sounds, such as those found in some languages in Africa, make perfectly good consonants. So why do they appear so rarely in most human speech? One culprit may be anatomy(骨骼).
Previous studies have suggested that in some speakers of click languages, the alveolar ridge(齿龈) the rounded bump between the upper teeth and the roof of the mouth-is small or even absent. In recent research, Scott Moisik of Nanyang Technological University in Singapore and Dan Dediu of the Max Planck Institute for Psycholinguistics in Nijmegen, the Netherlands, built biomechanical models that simulated clicks in vocal tracts(声道) with alveolar ridges of varying sizes. Their results, published in January in the Journal of Language Evolution, showed a clear disadvantage for tracts with large edges. These allowed less air to be trapped in the mouth, requiring more muscular force to produce a click.
The authors interpret this finding as support for an anatomical bias against clicks. They believe the bias is probably weak at the individual level; people with large alveolar ridges can still learn click consonants or that their pronunciations may be wrong. Amplified over generations, this bias might explain why such consonants are so rarely found in language worldwide.
These results are not the first to challenge the traditional premise among linguists that language evolution is largely immune to external factors. Several other researchers have recently argued that geographical context, environmental conditions and genetics could all play a role. But Moisik and Dediu’s work goes a step further by singling out a single feature of human anatomy and quantifying its contribution to a particular type of speech sound.
Susanne Fuchs, senior researcher at the Leibniz Center of General Linguistics in Berlin, who was not involved in the work, says the study’s conclusions are valid. But she cautions that they may present a chicken-and-egg problem: “The palate( 味蕾) shape of an individual matures from early childhood to puberty and , may be affected by frequent productions of clicks,” Fuchs says, “Therefore, over the course of history, it may well be that vocal tract properties and click productions developed in parallel.
1.The underlined word “one culprit” in Paragraph 1 means _____.
A.something that must cause suffering
B.something that may be the cause
C.something that could be concluded
D.something that never happened before.
2.According to the findings by Moisik and Dediu, who can make click sounds easily?
A.People with a small or absent alveolar ridge.
B.People with strong muscles inside the mouth
C.People with a normal alveolar rid.
D.People with a large alveolar ridge.
3.Which of the following statements is true?
A.People with large alveolar ridges cannot learn click language.
B.Having less air trapped in the mouth makes it easier to produce a click.
C.Both Moisik and Dediu believe that language evolution is largely independent of external factors.
D.Language evolution may be subject to geographical context, environmental conditions and genetics.
4.What is Susanne Fuchs most likely to agree with?
A.The conclusions of the study by Moisik and Dediu are unreliable.
B.Vocal tract properties and click productions might evolve at the same time.
C.Frequent productions of clicks decide the palate shape of an individual.
D.The palate shape of an individual decides whether one can produce click sounds.

Hardly any of us have experienced real violence, but, over the last few years, attacks on innocent people have increased. Each of us has some ability to defend ourselves, and by learning a form of self-defence, we are not only increasing that ability, but also doing something to build our own sense of respect. Karate will show you a lot of simple and effective techniques to protect yourself, giving you increase self-confidence.
Far too many people think martial arts (武术) are about violence. Martial arts training is based on a lot of respect, self-discipline, self-control and non-violence. We learn basic etiquette, courtesy and tolerance. Good manners and consideration for others are expected at all times.
Karate is the practice of blocking and striking techniques for the purpose of self-defence, health and self-development. Karate exercises the entire body. Techniques are practised on both sides of the body, therefore muscle imbalances do not occur and the strength, coordination, flexibility and agility of both sides of the body are improved. Regular training in Karate improves the body’s physical endurance and flexibility. It also helps concentration and produces the mental calm and assurance that come from knowing we can defend ourselves.
Karate has many benefits but they do not come easily or overnight. Training requires ongoing commitment and hard work. Some of you will give up, but a few of you will get your black belt.

Every April I am troubled by the same concern -- that spring might not occur this year. The landscape looks dull, with hills, sky and forest appearing gray. My spirits ebb, as they did during an April snowfall when I first came to Maine 15 years ago. "Just wait," a neighbor advised. "You’ll wake up one morning and spring will just be here."
And look, on May 3 that year I awoke to a green so amazing as to be almost electric, as if spring were simply a matter of flipping a switch. Hills, sky and forest revealed their purples, blues and green. Leaves had unfolded and daffodils were fighting their way heavenward.
Then there was the old apple tree. It sits on an undeveloped lot in my neighborhood. It belongs to no one and therefore to everyone. The tree’s dark twisted branches stretch out in unpruned（未经修剪的） abandon. Each spring it blossoms so freely that the air becomes filled with the scent of apple.
Until last year, I thought I was the only one aware of this tree. And then one day, in a bit of spring madness, I set out with pruner to remove a few disorderly branches. No sooner had I arrived under the tree than neighbors opened their windows and stepped onto their porches(门廊). These were people I barely knew and seldom spoke to, but it was as if I had come uninvited into their personal gardens.
My mobile-home neighbor was the first to speak. "You’re not cutting it down, are you?" she asked anxiously. Another neighbor frowned as I cut off a branch. "Don’t kill it, now," he warned. Soon half the neighborhood had joined me under the apple tree. It struck me that I had lived there for five years and only now was learning these people’s names, what they did for a living and how they passed the winter. It was as if the old apple tree was gathering us under its branches for the purpose of both acquaintanceship and shared wonder. I couldn’t help recalling Robert Frost’s words:
The trees that have it in their pent-up buds To darken nature and be summer woods One thaw led to another. Just the other day I saw one of my neighbors at the local store. He remarked how this recent winter had been especially long and complained of not having seen or spoken at length to anyone in our neighborhood. And then, he looked at me and said, "We need to prune that apple tree again."

A.They were surprised that someone unknown was pruning the tree.
B.They wanted to prevent the author from pruning the tree
C.They were concerned about the safety of the tree
D.They wanted to get to know the author
4.It can be inferred that the author’s neighbor mentioned in the last paragraph most cared about _____.
A.when spring would arrive B.how to pass the long winter
C.the neighborhood gathering D.the pruning of the apple tree
Saddleworth Moor in the north of England is a bare place. It seemed almost wired to me, then, that anyone should _____ the building of seven wind turbines( 风力发电机) to produce clean, renewable energy. Surely this was the perfect place to situate them--- basically dull, unattractive to tourists and ----- _____ ---windy. Yet Saddleworth is becoming another battleground in an increasingly confusing _____ over wind farming and the future of the planet.
Typical of this confusion is hearing Professor David Bellamy _____ the fight against wind farms. I had always thought of Professor Bellamy as an environmentalist had made the _____ assumption that he would be a natural supporter of wind power. However, on reflection, Bellamy would be better described as a conservationist, whose main aim is to preserve natural habitats of plants and animals from destruction, rather than a(n) _____ on climate change. He has fought against other renewable energies that _____ wildlife and wildness, and has described the wind turbines as weapons of mass destruction killing birds and bats.
Bellamy, along with other opponents, has argued the wind farms are in fact _____, and are only commercially successfully because they are so heavily funded. This argument has been put forward by several newspaper commentators recently , who have then gone to _____ nuclear power. This doesn’t take into account years of _____ from Greens who claim that nuclear power is both expensive and dangerous. And yet nuclear energy has recently been _____ by a leading green scientist , Professor James Lovelock, who was one of the first to draw attention to the problem of climate change. He argues that renewable energy such as wind simply cannot provide sufficient electricity for our energy needs.
And so it goes on. There are so many _____ claims, each apparently fronted by some outstanding scientists and backed up by a lot of statics. So who’s actually right? What’s the right solution? What _____ me is that we will take so long in deciding that it will be too late. The damage will have been done. Yet what I also _____ is how convenient these conflicting arguments are. We can avoid making any changes to our personal lifestyles by just doing nothing. Global warming isn’t down to me going to Barcelona by air for the weekend or having a dishwasher or driving everywhere; no, it’s because those people in Saddleworth won’t let us build our _____!
