The US will have a new president this fall. Voters will decide between the Democratic candidate (候选人), Hillary Clinton, and Donald Trump of the Republicans.

    But the voting is not a must for each person in the US. So quite a lot of people choose not to vote, especially the young generation. According to Fox News, one-in-five young voters between the ages of 18 and 35 said clearly that they wouldn't vote for either of the two candidates. Just 12 percent of voters aged 35-54, and only nine percent of voters aged 55 and older said the same thing.

    This is not only because young people don't like Clinton or Trump, according to the Fortune magazine. The truth is that they are traditionally less likely to vote than their parents.

    “Young people are not at an age in their life when they think politics or government has anything to do with them,” said Rodd Freitag, a political science professor at the University of Wisconsin-Eau Claire, US. “But for the older age groups, they have a home, they pay taxes (税), they care about schools and the community.”

    Many believe that the civic (公民的) education of an American youth is another reason why they don't vote.

    Students usually just do community services like cleaning the neighborhoods. This means they haven't learned how to link real life problems to politics through voting, according to Christopher Beem, a politics professor at the Pennsylvania State University.

    He said the country needs to help young people learn how to take part in politics and get them to see that they can make a difference.

    Being mistreated at work can out their negative emotions on loved ones at home. But a new study suggests that getting more exercise and sleep may help people better pope with them by, leaving them at work where they belong.

    Previous research shows that employees who are looked down on or insulted by colleagues are likely, go express their frustrations and behave angrily toward people outside of work, says study co-author Shannon Taylor, a management professor at the University of Central Florida's College of Business.

    The new study backs up this idea, but offers a bit of good news as well: Employees who averaged more than 10.500, steps a day or burned at least 2, 100 calories were less likely to mistreat their cohabitants than those who averaged fewer steps of burned fewer calories.

    The findings also revealed that when employees felt they had a bad night's sleep because of work issues, they, were more likely to be grouchy at home. “When you're tired, you're either less able or less motivated to regulate yourself” says co-author Larissa Barber, a professor of psychology at Northern Illinois University.

    Physical activity seems to counterbalance poor sleepy, Barber says, because it promotes healthy brain functions needed to properly regulate emotions and behaviors. “This study suggests that high amounts of exercise can be at least one way to improve the situations brought by sleep troubles that lead to negative behaviors at home,” she says.

    Barber acknowledges that finding time to work out and get a full night's sleep can be difficult when work pressure is mounting, and that often, job stress can be directly related to sleep quality. But, she says, making the effort to burn some extra calories and blow off some steam can be worth it. It's not only good for you, says Taylor,/ but it can benefit the people you live with as well.

    With the wide, application of the Internet, Uber, a new approach to your destination instead of taking an ordinary taxi, has become more popular recently. However, benefits won't come without its fair share of drawbacks. The ride-sharing experience is about to get awkward.

    Uber drivers are a part of the so-called sharing economy: They use their own vehicles, receive customer reviews via the app's five-star rating system and make their own hours and choices. Unlike other services, Uber claimed that drivers all over the country could dearly alert customers that tipping is not included. Those drivers that expect to be tipped can make their wishes known. But the company is holding to its official no-tip-required line. “Once you arrive at your destination, your fare is automatically charged to your credit card on file－there's no need to tip.” Although drivers value the freedom to push a button rather than punch a clock like ordinary taxi drivers, lack of a clear policy leaves Uber drivers m a vulnerable (脆弱的) and awkward position: If they ask a customer for a tip or put up a sign, that customer could give the driver a low star-rating, and the driver could finally be removed from the app.

    But has the company done a good job working with customers? Some observers say that this new grey area for tipping will create awkwardness about whether they should tip or not. Providing an option to tip on an app sends a clear message to customers to reach into their pockets. According to Guinn's 2015 survey of roughly 500 people, merely 30% people would be more likely to leave a tip if they were presented with a “no tip” button.

    If the service is twice as expensive during a rain storm or public transport delay, the customer has the right not to tip, However, if the driver is extra helpful or avoids traffic to reach your destination in a more timely manner, you could give an extra tip, says Uber, who will leave tipping options in the hands of the consumer rather than the app.

    Trees are useful to man in three very important ways: they provide him wood and other products; they give him shade; and they help to prevent drought (干旱) and floods.

    Unfortunately, in many parts of the world, man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers.

    Two thousand years ago, a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became bare and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

    Even where a government realizes the importance of a plentiful supply of trees, it is difficult sometimes to make the people realize this. They cut down the trees but are too careless to plant and look after new trees. So unless the government has a good system of control, or can educate the people, the forests slowly disappear.

    This does not only mean that there will be fewer trees. The results are even more serious: for where there are trees, their roots break the soil up, allowing the rain to sink in, and also bind the soil. This prevents the soil from being washed away. But where there are no trees, the rainfalls on hard ground and flows away on the surface, and this causes floods and the rain carries away the rich top soil in which crops grow. When all the top soil is gone, nothing remains but worthless desert.

    I stopped to watch my little girl busy playing in her room. In one hand was a plastic phone; in the other a toy. I listened as she was speaking to her make-believe little friend and I'll never forget the words she said, even though it was imagined.

    She said, "Suzie's in the corner because she's not been very good. She didn't listen to a word I said or do the things she should." In the corner I saw her baby doll well dressed. It was obvious that she'd been put there to sit alone and think.

    My daughter continued her "conversation", as I sat down on the floor. She said, "I'm all fed up and I just don't know what to do with her any more. She cries whenever I have to work and wants to play games too. She tries to help me with the dishes, but her arms just cannot reach... And she doesn't know how to fold towels. I don't have the time to teach. I have a lot of work to do and a big house to keep clean. I don't have the time to sit and play - don't you know what I mean?"

    And that day I thought a lot about making some changes in my life, after listening to her innocent words cut me like a knife. I hadn't been paying enough attention to what I hold most dear. I'd been caught up in responsibilities that increased throughout the years.

    But now my attitude has changed because in my heart I realize that I've seen the world in a different light through my little darling's eyes. So let the cobwebs (蜘蛛网) cut the corners and the dust bunny rabbit rule the floor. I'm not going to worry about keeping up with them any more.

    I'm going to fill the house with memories of a child and her mother, for we have only one childhood and we will never get another.
