2.【2017年山东青岛】阅读理解 阅读下列短文，做出正误判断或选出最佳答案。

Our skin is like a bag that we live in. Inside the bag our bodies are mostly water. Our water is like the water in the sea. It is very salty. Also, like the ocean, we can lose our water. The wind and the sun could take it away. Our bag of skin keeps our body’s ocean from drying up. Our skin keeps out sunshine. Too much sunshine can hurt us. Skin also keeps out dirt. That’s important because some kinds of dirt can make us sick. Our skin feels things. It feels warm things, cold things, things it touches, and things that hurt it. A campfire feels warm. A snowball thrown in our face feels cold and hurts us. A hug is the touch of another person’s skin on our own.

Our hair is a special kind of covering. It helps us keep things out of our eyes, ears and nose. Hair is also good for keeping us warm. When we get goose bumps (鸡皮疙瘩), our body hairs stand up. Then the hairs hold air close to our skin like a thick blanket (毯子). Hair keeps animals warm, too.

Some animals have more hair than others, so they have a better blanket for cold weather. Our nails (指甲) are another special skin which are very hard. They help keep our fingers from getting hurt. Our nails aren’t as strong as the nails that animals have. But they are good for picking up coins.21世纪教育网版权所有 1. Our skin is like a bag full of salt. 2. Our skin keeps out dirt and sunshine.

You don’t need to get in a time-travelling machine to see how technology will change our lives, such as the way we shop. Several new technologies that are to change your buying habits already appear. Let’s see what’s in store for your future shopping.21cnjy.com

Try it on, virtually（虚拟地）. Want to shop online for a new pair of glasses? You don’t need to guess which pair looks best on you—use the eBay Fashion iPhone app to try a pair of glasses you’re checking out on a picture of your face. But what about buying something bigger? Thanks to Microsoft Kinect’s action tracking（跟踪）camera, you can cover clothes on your screen body. You can even choose the background of your virtual fitting room to improve your shopping experience. Get a perfect, custom fit. Everyone’s body is shaped differently. To get a perfect fit, you sometimes have to get your clothes changed. But by using 3D scanning technology, all the clothes you buy will fit your body perfectly. Some companies scan（扫描）your body using High-tech to get the real sizes, so they can make special clothes just for you.21教育名师原创作品

If we don’t want to wait in line before the checkout counters, we can use Toshiba’s new object Recognition Scanner. The machine identifies（辨认）a product as soon as it’s placed in front of a camera just by its shape and color, even
