    Devon, 17, is used to paying her own cell phone and car expenses. But lately it's been harder. The family she baby-sits for hasn't been calling as much as usual and she couldn't find a job over the summer. Devon's dad said it's a sign of the tough economy. He told her he's feeling the pinch too and that he had to use her college fund to pay the loan(货款).

    This kind of money troubles isn't strange to common families these days. In fact, it's hard to avoid news about the economy on the screen of the TV or the computers recently. It can seem a bit worry and some families are hit really hard.

    For most people, the big problem is that things cost more at a time when they have less money to spend. But higher prices aren't the only problem. Many people are having a tough time making payments on some types of home loans.

    Therefore, some families are cutting back on what they spend.  For example, eating out less, staying home instead of going on vacation, moving to a less expensive house and so on.

    However, as discouraging as things may seem now, the good news is that the economy always gets back on track after a while. Jobs may be hard to find, but the slow economy can open up new opportunities. The couple Devon babysat for might cut back on evening's out, but they could be interested in hiring her for after-school care. Perhaps it's time to sell her old toys and baby gear (设备)in the basement(地下室) or help others sell these items online if she is good at it. She could charge them a fee to sell their old stuff(东西).

    What does it take to be a good neighbor ? Over the years I have had all kinds of neighbors.ones that were enjoyable and others that were to be avoided at all costs.

    One of the most important things in being a good neighbor is to respect a person's privacy(隐私).When someone new moves into the neighborhood it is a good idea to watch them to see how friendly you should be if you go rushing over as soon as they move in they may think you are going to be one of those neighbors that come over at all times of the day,not respecting their privacy.

    It is a good idea always to be friendly to everyone in the neighborhood.This can not only put you on good terms with them,but will also be a form of protection for your family and home.If you wave as they drive by or offer a friendly hello while they are out in their yard this shows that you respect them.If you are friendly do them they are much more likely to watch out for any wrong doings going on around your home while you are out and let you know if anything happens.

    Another way of being a good neighbor is to be helpful in times of need.If you see that they are in need of a helping hand doing something or in times of a disaster,it is good to offer your help.Even though you have never really talked to the people down the street,they are willing to take the time to help out a neighbor in need.

    In conclusion,if you respect a person's privacy,treat them kindly and be helpful when you see they are in need,you will be a great neighbor and anyone would be happy to have you next door!

    You can't always predict a heavy rain or remember your umbrella. But designer Mikhail Belvacv doesn't think that forgetting to check the weather forecast before heading out should result in you getting wet. That's why he created lampbrella, a lamp post with its own rain sensing umbrella.

    The designer says he come up with the idea after watching people get wet on streets in Russia. “Once, I was driving on a central Saint Petersburg street ad saw the street lamps lighting up people trying to hide from the rain. I thought it would be appropriate to have a canopy(伞蓬)built into a street lamp.” he said.

    In addition to the rain sensor, there's also a 360°motion sensor on the biberglass street lamp which detects whether anyone's using the lampbrella. After three minutes of not being used the canopy is closed.

    According to the designer, the lampbrella would move at a relatively low speed, so as not to cause harm to the pedestrians. Besides, it would be grounded to protect from possible lighting strike. Each lampbrella would offer enough shelter for several people. Being installed at 2 meters off the ground, it would only be a danger for the tallest of pedestrians.

    While there are no plans to take lampbrella into production, Belyacv says he recently introduced his creation one Moscow Department, and insists this creation could be installed on my street where a lot of people walk but there are no canopies to provide shelter.

    Children are starting on digital devices at ever younger ages, and opinions on the effects of children's digital-media habits are deeply polarised.(两极分化的).

    Jean Twenge, a psychology professor, thinks excessive use of the internet and social media makes children lonely and depressed and poses serious risks to their physical and particularly their mental health, sometimes to the point of driving them to suicide.

    However, Daniel Kardefelt-Winther of the Innocenti research office of Unicef examined various evidence and found less cause for alarm than is often suggested. Most of the studies he examined seem to show that the technology helps children stay in touch with their friends and make new ones.

    The relationship between the use of digital technology and children's mental health, broadly speaking, appears to be u-shaped. Researchers have found that moderate use is beneficial, whereas either no use at all or extreme use could be harmful.

    What worries some experts more is that screens are becoming part of the middle-class armoury(武器) for perpetuating(巩固) social advantage. Children from well-off homes are enrolled in private classes to learn skills like "How to be a YouTuber", which poorer parents cannot afford.

    It was dinner time for the Rangers, a group of mostly Indigenous (本地的) Australians who had spent a long day cleaning up the polluted beaches of the continent's northern coast. Soon they would be eating freshly caught fish and seafood cooked under the stars on an open fire, as their ancestors did.

    The Rangers are of more than 100 Indigenous groups spread across Australia who have taken on the job of protecting the land of their forefathers. In Arnhem Land, they are the protectors of 3,300 square miles of land and sea. They comb the beaches by hand, picking up as much rubbish as possible. The task is very difficult as each day it delivers waves of new rubbish.

    For the Rangers, cleaning the beaches is more than a vacation. For a people whose culture is strongly tied to the land, protecting the environment is equal to preserving their history.

    However, colonization forcefully broke their connection to the land generations ago. Indigenous people were displaced and their cultural practices outlawed. Tens of thousands of years of traditional land management ended, and as a result many parts of the country now face serious disasters from invasive plant and animal species, bush fires and land mismanagement.

    In recent years, the government has restored more than 20 percent of Australia's land to Indigenous owners. Since 2007, the Indigenous Rangers Organizations have been at work protecting this land.

    Luck, one of the few non-Indigenous employees working with the Rangers, said the combination of old and new techniques and an appreciation for the culture of Indigenous workers has been critical to the program's success.

    "You are working with staff who see the world different to you, so there is a much higher focus on the cultural aspects of work and life," he said.

    "Being a ranger is a source of confidence. You feel strong," said Terence, a senior ranger. "Here we still live on the land. The culture is still alive."
