【推荐1】Why you shouldn't punish your kids for lying

Getting your children to stop lying is challenging. There are many influences（TV，movies and video games）in which lies are common. Children see parents lie to others，if only to be polite. Most parents add to that with tales about the lives and activities of Santa Claus or the tooth fairy.     1    

The most common reactions to children who lie are explaining why it is wrong and punishments.     2     Here are three better tools supported by research to use instead.

Give praise: You could ask your child to say something that happened at school that is true. When your child obeys, praise him enthusiastically. Be specific.     3     and give your child a hug or a high five. Aim for one or two interactions（互动）like this a day. If you happen to "catch" your child in a lie，say something like，“That is not true and could get you in trouble outside of the home.”

Act as a model: Explicitly（明确地）tell the truth. This could be about something that happened when you were a child or something that happened during the day. It need not be dramatic. Another option is to play a game at dinner. Each person tells one thing that was true that day. Again，give a little praise to the child who normally lies if she plays along.

Decrease punishments and moralizing（说教）：They are unlikely to change behavior or develop the conduct you want.     4     Rather，use very mild punishments（light scolding，short loss of privileges，a brief timeout）. More severe punishments（shouting，taking away something for a week，hitting）are not more effective in actually changing the frequency of lying.

    5     Usually they can be dropped by then. It is unlikely that lying will be completely removed，but with the right encouragement，it can be dramatically lessened.

【推荐2】The healthy adolescent boy or girl likes to do the real things in life,to do the things that matter.He would rather be a plumber’s mate and do a real job that requires doing than learn about hydrostatics(流体静力学)sitting at a desk, without understanding what practical use they are going to be.A girl would rather look after the baby than learn about child care.Logically we should learn about things before doing them and that is probably why the experts enforce this in our educational system.But it is not the natural way---nor,in my view,the best way.The adolescent wants to do things first for only then does the appreciate the problems involved and want to learn more about them.

They do these things better in primitive life,for there at puberty(青春期) the boy joins his father in making canoes,patching huts,going out fishing or hunting.He is serving his apprenticeship in the actual accomplishments of life.It is not surprising that anthropologists(人类学家) find that the adolescents of primitive communities do not suffer from the same neurotic(神经质的) “difficulties” as those of civilized life.This is not,as some assume,because they are permitted more sexual freedom,but because they are given more natural outlets for their native interests and powers and are allowed to grow up freely into a full life of responsibility in the community.

In the 19th century this was recognized in the apprenticeship system,which allowed the boy to go out with the master carpenter,or ploughman,to engage in the actual work of carpentry or roof-mending,and so to learn his trade.In some agricultural colleges at the present time young men have to do a year’s work on a farm before their theoretical training at college.The great advantage of this system is that it lets the apprentice see the practical problems before he sets to work learning how to solve them,and he can therefore take a more intelligent interest in his theoretical work.

Since more knowledge of more things is now required in order to cope with the adult world,the period of growing-up to independence takes much longer than it did in more primitive community,and the responsibility for such education,which formerly was in the hands of the parents,is now necessarily undertaken by experts at school. But that should not make us lose sight of the basic principle,namely the need and the desire of the adolescent to engage responsibly in the real pursuits of life and then to learn how—to learn through responsibility,not to learn before responsibility.

They’re actually advertisements, or ads. The goal of an ad is to get you to buy something. How do you, the reader, tell the difference between a news story and an ad?

Back when I was growing up, it was easier. We got most of our information from newspapers. Big news stories appeared on the front page, and ads were boxed off and clearly labeled. But on the Internet, the two are often presented together. It can be hard to tell which is which.

That’s why the research group I direct conducted a study. My research team showed kids like you the home page of a popular digital magazine. We asked them to tell us what was a news story and what was an ad. Most were great at identifying certain types   of ads. “It has a coupon code, a big company logo, and the words limited time offer,” one student wrote about an ad on the site. So where did kids get stumped?

Some ads seem the same as real news stories. They have headlines and contain information. But they may also include the words sponsored content. Sponsored means “paid for,” and content refers to the information in the story. “Sponsored content” is a way of saying that something is an ad. Most kids in our study, even if they used the Internet often, didn’t know this.

Just because something is sponsored doesn’t necessarily mean it’s false. It means someone paid money for it to appear. Companies pay so that readers will see their stories, buy their products, and like what the company stands for.

As a reader, you have a right to know who’s behind the information you’re consuming. So look for the phrase sponsored content. (And look carefully. Sometimes, it will be written in tiny letters.) The Internet is a vast sea of information. To use it well, we not only have to know how to swim but also how to avoid the sharks. Learning to tell the difference between an ad and a news story is an important step to becoming Internet smart.

Two web security experts hacked (侵入) into its Wharf 7 office in Sydney, Australia, through Google’s building management system (BMS). One of them, Billy Rios, says, “My colleague and I have a lot of experience in web security, but it is not something that people couldn’t learn. Once you understand how the system works, it is very simple.”

They found the system on Shodan, a search engine that lists devices connected to the Internet, and then ran it through their own software to identify who owned the building. In the case of the Google hacking, the researchers had no immoral purpose and just informed Google about what they found.

According to Mr. Rios, Who runs security company Whitescope, there are 50,000 buildings currently connected to the Internet, including research institutes, churches and hospitals, and 2,000 of those are online with no password protection. Martyn Thomas, a professor of IT at Gresham College in the UK, says, “It is beyond doubt that attempts to attack building management systems are happening all the time.”

Making a building smart generally means connecting the systems that control heating, Hating and security to the Internet and the wider corporate network. There was a strong reason for doing this, said Andrew Kelly, principal security consultant at defence company Qinetiq.

“Energy savings are the biggest factor in connecting building management systems to the corporate network,” he says. “It gives those who run the building better control and offers between 20% to 50% in energy savings,” he adds.

But it also makes them less secure. And if any of these feels like a Hollywood film, think again.

【推荐2】India's richest man is rolling out a $20 billion mobile network that could bring lightning-fast Internet to hundreds of millions of people. Indian consumers are already celebrating the arrival of Mukesh Ambani's new Reliance Jio service, seizing on the billionaire's promise to deliver rock bottom prices and download speeds that will enable streaming video.

The 4G network, which reaches more than 80% of the country, officially went live Monday with a set of generous introductory offers. Indians will be able to use Jio for free until the end of 2016, and pay as little as 149 rupees ($2.25) a month for data after that. "Anything and everything that can go digital is going digital -- at an exponential rate," Ambani told investors last week at his company's annual general meeting. "Life is going digital."

Only one fifth of adults in India have access to the Internet. Few public Wi-Fi spots exist, and fast broadband connections require infrastructure that is rarely found in poorer urban areas, much less rural ones. But that is changing fast. If the Jio network succeeds, Ambani will be able to capitalize on a seismic shift that could see hundreds of millions of Indians come online in the coming years -- in most cases via a smartphone.

Google has installed free Wi-Fi at train stations across India, and Facebook tried to offer a free version of its platform. Many other international companies are also trying to share the great market in India. Ambani has invested billions constructing nearly 100,000 telecoms(电信)towers across India. He estimates that Jio already covers some 18,000 cities and 200,000 villages. By March 2017, his aim is to reach 90% of the population.

Building a national 4G network from scratch represents a major risk for Ambani, who got out of telecoms about 15 years ago after a dispute with his brother, Anil Ambani, who controls Reliance Communications. The brothers, who together are estimated to be worth $26 billion, have patched things up in recent years. Jio will be able to use radio frequencies owned by Reliance Communications.

Rival(对手)networks have responded to the launch of Reliance Jio with special offers of their own, making a price war a near certainty. Airtel has reduced its prices for 3G and 4G service by 80%, and Vodafone has boosted the amount of data in its plans by nearly 70%.

【推荐2】Astronauts in America who fly into space need special training. First they go to Huston, Texas. That is the home of the Johnson Space Center. There they are tested to see how strong and smart they are.

The first test is for the heart. The people walk or run, and then the space doctors see how fast their hearts beat.

Another important test is performance. In this test, the person must curl (蜷曲) his body up in a ball. When he is in that position (姿势), he is put into a round cloth bag. The doctors give him no idea how long he will have to stay in the bag. If a spaceship broke down in space, the astronauts would get into bags like this. Then they would have to wait and curl up in darkness until help could arrive. You can see that an astronaut must not be afraid of tight space or darkness.

After the tests, only the best people are chosen to start astronaut training in a training center. The astronauts in training learn many other things. They learn how to jump out of a moving airplane. They learn to blow up a lifeboat and get into it while they are in the ocean. The astronauts also have to learn how to get lifted out of the ocean by helicopter. That seems fun, but it can be dangerous.

After they finish training, the astronauts continue to work. They stay in good shape by running and doing exercise. They read about their special jobs. In this way, they can learn new facts about space travel. Then the big day comes. The astronauts are told to go to work on a flight into space.
