    When you lose something you can go to a place called the lost and found office. People often  1 things when they're travelling or when they are  2  a hurry. Other people 3 these things and send them to the lost and found office. We can see some lost and found  4 at schools, stations, parks and other places. People may lose   5  things, such as mobile phones, books, ID cards, watches and cameras.

    There's one loat and found office at our school. There you can   6  books, ID cards, watches and many other  7 . Even there are some school uniforms there. Are you   8  your lost things? Come  9have a look at them. Perhaps you can find them there. It can be   10helpful.

    Electricity is all around us. It's in the computer you are using, it's in the ground under your feet, and it's in your body. And you can't live without electricity.

    Without electricity, you wouldn't be reading this article right now. It's not because it's not bright enough without electricity. It's because your brain wouldn't work.

    Every move of your body needs the help of electricity. The nervous system(神经系统）sends electrical signals（信号）to your brain first, and then your brain sends them to your body. These signals don't flow along a wire. They jump from one cell（细胞）to the next until they get to their final place.

    With so much electricity jumping around, it may seem like the body is a great power station. You may wonder if you have enough power to turn on TV. Well, your body can just create little electricity. So stop dreaming.

—Yes, I saw quite a lot.
