【题目】A
Do you remember your dreams? Do people have the same dreams? Why do I dream?
There are many questions about dreams. We dream during the REM(快速眼动) stage of sleep. We have about five periods of REM sleep during the night. The first REM cycle(周期) lasts about 10 minutes. As the night goes on, the REM cycle gets longer. By early morning, the REM cycle can last up to 90 minutes. Usually, it is in this last REM cycle that we remember our dreams.
Dreams change as people age. People may have several dreams each night. Some are like films and usually in color. They come to us over and over again. That may be because the dreamer is worrying about something and trying to find the answer. Sometimes we wake up with a good feeling from a dream. But often we can’t remember the dreams clearly.
It is reported that too much dreaming is bad for our health. The more we sleep, the longer we dream. The mind is hard at work. That is why we may have a long sleep and still feel tired when we wake up.
Do you feel a little sleepy after lunch? Well, that’s normal. Your body naturally slows down then. What should you do about it? Don’t drink coffee, take a nap, instead. There are many advantages of a daily nap. First of all, you can remember things better and make fewer mistakes. Also, you can learn things more easily after taking a nap. A 20-minute nap can reduce your pressure. Finally, a nap can make you cheerful.
But, there are some simple rules you should follow about taking a nap. First, take a nap at noon, about eight hours after you wake up. In general, a 20-minute nap is the best. If you sleep longer, you may fall into a deep sleep. After waking up, you will feel worse. Also, you should set an alarm clock. That way, you can fully relax during the nap. You don’t have to keep looking at the clock so that you don’t oversleep. Now, next time you feel sleepy after lunch, don’t get stressed. Put your head down, close your eyes and take a nap.

【题目】用如图所示的方法可以探究做功是否能够改变物体的内能：
如图1，将手中的铁丝同一位置快速地弯折十余次，用手指触摸一被弯折的部位，会感觉到弯折部位的 升高，表明铁丝的内能 ；如图2，在厚壁的玻璃筒底部放一小撮干燥的棉絮，用力将活塞压下，我们会看到：棉絮 了，这表明用力压下活塞时，玻璃筒内的温度 并达到棉絮的 ，所以出现了我们所看到的现象．
上述的这两个现象都说明了 是改变物体内能的另一种方式．用能量的观点来分析上述的两个现象，我们发现，用这种方法改变物体的内能时，能量是在 能和 能之间相互转化的．
