    Lots of kids like to play computer and mobile games these days. Is this good or bad for us? How do we deal with this issue?

    In my opinion, playing games responsibly(负责任地)can help us relax. As the old saying goes," All work and no play makes Jack a dull boy. "For example, when I finish five days of studying, I feel tired. That's when I like to play a game called King of Glory with my classmates. We all have lots of fun playing and talking about it. When we win, we feel happy. And when we lose, we still want to play more. I think that's why so many students in our school like to play this game. It can not only help us relax, but also strengthen our friendship.

    In addition, playing games can exercise our brains and help us think more quickly. When we start to play a new game, we're not very good at it. But we can get better through practice. This process exercises our brains and makes them more active. However, you should make sure that you have finished all of your homework before you play games.

    Still, some students seem like they are addicted(上瘾的)to games. They can't control themselves and will play games for five hours a day. That is not good. It's bad for not only their eyes, but also their health. They will feel tired in class the next day, which will affect(影响) their studies. That's not very responsible.

    Therefore, I can only say that we should try to be self-disciplined(自律的)and responsible when working out how much time we should spend playing video games.

Five tips for a successful yard sale

    Each summer, yard sales become popular and many people come to yard to get great deals on second-hand objects. Have you ever had a yard sale? What can you do to hold a successful yard sale? Here are five tips for you.

    {#blank#}1{#/blank#}

    Every yard has its own advertisement. The best as is signs. Draw some big signs with just "Yard Sale" and a large arrow(箭头) on a board in front of your yard. Pointing customers(顾客) in the right way is always better than just putting your address on the sign and hoping they know how to get there.

    {#blank#}2{#/blank#}

    The more organized you are, the less busy it will be in the morning of your yard sale. You want to make sure that you have everything set up before people arrive so you can have more time for answering questions and collecting money.

    {#blank#}3{#/blank#}

    This is something a lot of people don't think about when preparing for a yard sale. You don't want to turn away customers because you don't have enough change. I suggest at least $50 in change, which means mostly $1's and $5's

    {#blank#}4{#/blank#}

    Running a yard sale on your own can be really stressful, especially if you have a lot of objects to sell. It's hard to run inside to go to the bathroom or try to talk to and collect money from several customers at once. Ask a friend or two if they have something they'd like to sell too and that way you'll have some help in case things get busy or you need a break to get a drink or some food.

    {#blank#}5{#/blank#}

    Yard sales are fun and you can make a good amount of money. It's also a good chance for you to chat with your customers, make them feel comfortable, and enjoy yourself.
