Garbage or trash is a major kind of environmental pollution.Each person produces about 2kg of trash a day.We are making waste products faster than nature can break them down.And we are using up resources（资源）faster than they can be replaced（取代）.

    This adds up to trouble for the environment.Where does all that garbage go?What can be done to help dispose of（处理）garbage?How call we make less garbage?

    Garbage isn't just the smelly rotting fruits,vegetables or meat that we throw away in our homes.Those are only a small pan of all the stuff we throw away.We create other kinds of waste,in construction,mining and in our factories.

    Did you ever wonder what happens to your garbage?Most is burned or buried in landfills（垃圾填埋场）Less than a quarter of our waste is recycled.

    With a population of 1.3 billion（十亿）,garbage is a big problem for China.Chinese cities create around 148 million tons of garbage every year.The amount is growing at around 10 percent each year.

    Once we used about 3 billion plastic shopping bags every day in China.The result was a great waste of resources and serious pollution.So we did something about that.Now we use more cloth bags and shopping baskets when we shop.

    In the coming years China will build waste-to-energy plants in cities to clean up the garbage.But there's a lot more that needs to be done.And you can play a part.

    Science is always advancing over time. A self-driving car from the Google may be coming to a street near you. However, you won't be able to buy it now. “We're working to build the world's most experienced driver,” Kraft, director of the project, said. “Everything that we learn in one of our cars gets passed to all of our cars. But you may need to get over the idea of traditional car ownership along the way.”

    Google's software has already driven 5 million miles in U.S. cities, including an “early rider” test in Phoenix last April. Since then Google has grown confident enough to remove the “auxiliary wheel”: a human “safety driver”. Powering the vehicle's self-driving functions is a series of cameras, radars and sensors on the car's roof, which detect everything nearby from other vehicles and passers-by to cyclists.

    Kraft stressed that Google's cars aren't connected—they don't need a 5G wireless link to go anywhere. “The car has everything it needs to drive on the car itself.” He said, “There are no signals coming from outer space or something telling it to turn right.” The resulting ride may not be too exciting but safe. Kraft added. “We can see three football fields down the road, we would come to a stop before we ran into these crowds.”

    Google's system has a major advantage over the semi-autonomous（半自主的）systems of Tesla and Cadillac, both of which need continued human attention. Kraft said Google plans to have service in every major city by 2028 with thousands of cars driving themselves.

    A handsome man can earn a fifth more than a plainer colleague (同事) but a beautiful woman is not paid a penny more than her average-looking colleague, new research has shown.

    The study by senior economists (经济学家) found that being good-looking meant male workers could earn 22 percent more than average-looking colleagues. Researchers said good looks did not give women a similar advantage.

    Andrew Leigh, the former economics professor at the Australian National University who co-authored the report, said: "Beauty can be a double-edged sword for women."

    "Some people still believe good looks and intelligence (智慧) are incompatible (矛盾的) in women so a good-looking woman can't be that productive, but it doesn't affect men's pay."

He said that although he believed good-looking women may also earn more, the research did not support his theory.

    The research found that handsome men in all jobs, from manual labour to highly-paid professional careers, can earn 22 percent more than their colleagues doing the same work.

    Men with below-average looks face a battle in the office, with ugliness reducing a man's earnings by 26 percent compared to an average-looking worker.

    Former male model Ian Mitchell, 28, who has a first class degree in history from Edinburgh University and now works for a cosmetics (化妆品) company, told the Sunday Times: "It gives you confidence, and I suspect people tend to warm to you more quickly."

    The study, named Unpacking the Beauty Premium, was the largest exercise of its kind and repeated a survey from 1984 to see if the beauty premium had changed.

    Leigh said the research showed people in the workplace were "lookist (以貌取人的) " and he hoped the findings would encourage employers to remove their prejudice(偏见).

    There are several ways from which to choose for you to keep your kids safe in your neighborhood. But the first step to keep your child safe in your neighborhood is to know your neighbors.

    Knowing your neighbors can save you a lot of worry. It lets you know that the car that has just driven down the street belongs to “the yellow house on the corner”, or the truck that has just driven by the playground looks unfamiliar, but the guy in the passenger seat resides two doors down. It's these simple things that keep you from going out of your mind whenever you see someone driving by where children are playing.

    But you shouldn't just know what they look like. The next step is to know them well. What do they do? How do they act? You might be OK with them driving by the playground since they live in the neighborhood, but are you OK with them being on the playground? Knowing your neighbors solves several things. First you find out what kind of people they are. This helps you know if you should let your child go out in an area where they gather. Let us face it: you do not want your child to play around people or people's children that curse (咒骂) or hit each other. Sometimes you have to protect your child against your own neighbors.

    Knowing them also makes them know you. Being neighbors is an interesting thing. You might not like them or have the same views as them, but we all usually protect those that we consider our own. If you know your neighbors, they know you. They are more likely to look after the child of the nice lady down the street in the brick (砖) house, than the people, in the house on the corner, who no one ever sees.

    Public transport is declining in the rich world. To those who have to squeeze onto the number 25 bus in London, or the A train in New York, the change might not be noticeable. But public transport is becoming less busy in those places, and passenger numbers are flat or falling in almost every American city. That is despite healthy growth in urban populations and employment.

    Although transport agencies blame their unpopularity on things like road works and broken signals, it seems more likely that they are being outcompeted. App-based taxi services like Uber and Lyft are more comfortable and convenient than trains or buses. Cycling is nicer than it was, and rental bikes are more widely available. Cars are cheap to buy, thanks to cut-rate loans, and ever cheaper to run. Online shopping, home working and office-sharing mean more people can avoid travelling altogether.

    The competition is only likely to grow. More than one laboratory is developing new transport technologies and applications. Silicon Valley invented Uber and, more recently, apps that let people rent electric scooters(滑板车) and then abandon them on the pavement. China created sharing-bicycles and battery-powered "e-bikes", both of which are spreading.

    Transport agencies should accept the upstarts, and copy them. Cities tend either to ignore app-based services or to try to push them off the streets. That is understandable, given the rules-are-for-losers attitude of firms like Uber. But it is an error.

    It is doubtful that most people make hard distinctions between public and private transport. They just want to get somewhere, and there is a cost in time, money and comfort. An ideal system would let them move across a city for a single payment, transferring from trains to taxis to bicycles as needed. Building a platform to allow that is hard, and requires much sweet-talking of traditional networks as well as technology firms. It is probably the secret to keeping cities moving.

Every New Year, thousands decide they're going to change their lives. Fewer than 10 percent actually stick with their plans, and that figure is being generous. {#blank#}1{#/blank#}.

Not aiming high enough. While it's easy to think setting easy goals will keep you motivated, it may harm your long-term motivation. If you make goals that are too achievable, you'll get bored and lose interest. {#blank#}2{#/blank#}. If you're used to staying within your comfort zone, you'll be missing out on the satisfaction of achieving a life-changing goal. When you push yourself, you'll be able to build unshakable confidence as you achieve goal after goal.

{#blank#}3{#/blank#}. This is a fear many of us deal with. Instead of taking action, we start worrying about " What if?" "What if it doesn't work out? What if my dream isn't truly my dream? What if I don't succeed?" If you have trouble creating a vision , then you're at the risk of being aimless through life. {#blank#}4{#/blank#}. You can start the process of discovering your life purpose by asking yourself, " What would my ideal life look like?"
