"If you want to see a thing well, reach out and touch it!" That may seem a strange thing to say. But touching things can help you to see them better. Your eyes can tell you that a glass ball is round. But by holding it in your hands, you can feel how smooth and cool the ball is. You can feel how heavy the glass is. When you feel all these about the ball, you really see it. With your skip, you can feel better. For example, your fingers can tell the difference between two coins in your pocket. You can feel a little drop of water on the back of your hand, too. You can even feel sounds against your skin. Have you ever wanted to know why some people like very loud music? They must like to feel the sounds of music. All children soon learn "what Don't touch!" means. They hear it often. Yet most of us keep on touching things as we grow up. In shops,we touch things we might buy, such as food, clothes and so on. To see something well, we have to touch it. The bottoms of our feet can feel things, too. You know this when you walk on warm sand, cool grass or a bad floor. All feel different under your feet. There are ways of learning to see well by feeling. One way is to close your eyes and try to feel everything that is touching your skin. Feel the shoes on your feet, the clothes on your body, the air on your skin. At first, it is not easy to feel these things. You are too used to them! Most museums are just for looking. But today some museums have some things which you can touch. Their signs say, "Do touch!" There you can feel everything on show. If you want to see better, reach out and touch. Then you'11 really see! When people buy things in shops, they often _ .

When I was a kid, I always used to wonder how in the world my father work outside in the winter without a coat. It could be minus 20 degrees centigrade and there'd be Dad, removing snow, or perhaps chopping some wood --- his coat thrown aside--- wearing a shirt , a cap, and a pair of gloves. "Aren't you cold, Dad?" I'd ask. "No," Dad would reply. "I'm not cold--- working too hard to be cold." Many times I wondered whether my father was an extremely tough man, or whether he was foolish. One time when I was quite young, perhaps five or so, I went ice fishing with Dad. It was a bright, clear day--and bitterly cold. After we'd been out on the ice for a little while, my feet started getting cold. "Daddy, my feet are cold." I said. "Yeah, it's cold out here today," he replied. "Tell you what," he said. "Walk around. Make some circles in the snow. See how many different patterns you can make. That will get your feet warm." Now, I was just a little girl at the time but I remember thinking, "How in the world will walking around in the snow make my feet warm? Dad must be out of mind. But he was my father, after all. I made circles in the snow. I made squares. Pretty soon I was having so much fun making patterns in the snow. I forgot about my feet being cold. Now, all these years later, I know, too, from personal experience how my father was able to take his coat off and work outside in the winter wearing just a shirt, a cap and gloves. Because I do it, too. "Aren't you cold?" my husband asked one winter day. "No," I replied. "I'm not cold--working too hard to be cold." I hope my husband has decided I'm both tough and smart. But I guess quite a bit of the time he thinks I'm foolish. Wherever Dad is in that great big farm in the sky--I'm sure he can't help but smile whenever I take my coat off while I'm working outside in the winter. What might the author's husband think of her? A) Tough B) Smart C) Brave D) Foolish

Let's do some sleep math.You lost two hours of sleep every night last week because of a big project due on Friday.On Saturday and Sunday,you slept in,getting four extra hours.On Monday morning, you were feeling so bright-eyed that you only had one cup of coffee, instead of your usual two.But don't be cheated by your energy.You're still carrying around a heavy load of sleepiness, or what experts call"sleep debt"----in this case something like six hours,almost a full nights' sleep. Sleep debt is the difference between the amount of sleep you should be getting and the amount you actually get.It's a deficit that grows every time we skim some extra minutes off our nightly sleep."People accumulate sleep debt gradually without being noticed,"says William C.Dement,founder of the Stanford University Sleep Clinic.Studies show that such short--term sleep deprivation leads to a foggy brain,worsened vision,and trouble remembering. Long-term effects include obesity,insulin resistance, and heart disease. A survey by the National Sleep Foundation reports that we're losing one hour of sleep each night----more than two full weeks of sleep every year. The good news is that,like all debt, with some work,sleep debt can be repaid. Adding an extra hour or two of sleep a night is the way to catch up.For the long--term lack of sleep,take it easy for a few months to get back into a natural sleep pattern. Go to bed when you are tired,and allow your body to wake you in the morning(no alarm clock allowed).You may find yourself catatonic in the beginning of the recovery cycle:expect to have ten hours shut-eye per night. As the days pass, however,the amount of sleeping time will gradually decrease. So earn back that lost sleep----and follow the dictates of your innate sleep needs. You'll feel better."When you put away sleep debt, you become a superman,"says Stanford's Dement, talking about the improved mental and physical capabilities that come with being well rested. The example of sleep math is used to show_. A) in what case you build up a sleep debt B) why you need six hours' sleep every night C) why you are full of energy even when you don't have enough sleep D) you should drink coffee to keep energetic when you don't have enough sleep
