It keeps your insides from falling out. It helps you warm up when you are cold, and it can cool you off when you are hot. It lets you feel things by touch.
What is this? Your skin（皮肤）, of course! What does you skin ask for return for all the wonderful things it does? Just a little care!  So let’s learn how to take care of our skin.
Like the heart and stomach, your skin is an organ （器官）．In fact, it is the largest organ in your body．Unless there’s a problem, you may not think about your skin very much．But skin has an important job to do．
Your skin is protecting you．Your skin keeps you from getting sick．When you take care of your skin, you are helping your skin do its job．Taking care of your skin today will help you have no problems in the future．
Clean skin is happy skin! One simple way to take care of your skin is to keep it clean．Keeping your hands clean is very important．When washing your hands, use warm water．Wet your hands, and then use soap．You should wash your hands carefully everywhere．
You’ll also want to use warm water, but not too hot, when you take a bath．Use soap to clean your body．Don’t forget under your arms and behind your ears! Your face needs attention, too．It’s a good idea to wash your face once or twice a day with warm water．
【小题1】We can infer（ 推断出 ）from Paragraph 3 that __

One of my favourite things to do is hiking in mountains. Because nobody likes the idea of getting lost, I always prepare before every trip. But what’s the best navigation tool, a Global Positioning System (GPS) or a good old map and compass? Five of my friends and I hiked through the mountains on a trail I marked. One team of three carried a GPS, and the other team used a map and compass.

It took the GPS team 3 hours and 11 minutes to get through the whole hike, however, it took the map and compass team only 2 hours and 49 minutes. The biggest problem the GPS team met was that they lost the satellite signal (卫星信号) in some places. With no map or compass, they had to walk around until they were in a place where the signal was good. The map and compass team was able to spot (认出) different landmarks, compare them to their maps and then use the compass to point them in the right direction.

When I head out on my future hikes, I’m bringing a map, a compass and a GPS to show me the way.
