Why do we go wrong about our friends or our enemies? Sometimes what people say hides their real meaning. And if we don't really listen, we miss the feeling behind the words. Suppose someone tells you, “You're a lucky dog.” Is he really on your side? If he says, “You're a lucky guy” or “You're a lucky gal,” that's being friendly. But “lucky dog”? There's a bit of envy in those words. Maybe he doesn't see it himself. But bringing in the “dog” bit puts you down a little. What he may be saying is that he doesn't think you deserve your luck.

　　“Just think of all the things you have to be thankful for” is another noise that says one thing and means another. It could mean that the speaker is trying to get you to see your problem as part of your life as a whole. But is he? Wrapped up in this phrase is the thought that your problem isn't important. It's telling you to think of all the starving people in the world when you haven't got a date for Saturday night.

　　How can you tell the real meaning behind someone's words? One way is to take a good look at the person talking. Do his words fit the way he looks? Does what he says square with the tone of voice? His posture? The look in his eyes? Stop and think. The minute you spend thinking about the real meaning of what people say to you may save another mistake.

　　Questions 26 to 30 are based on the following passage:

　　Sleep is part of a person's daily activity cycle. There are several different stages of sleep, and they too occur in cycles. If you are an average sleeper,your sleep cycle is as follows. When you first drift off into slumber (安睡), your eyes will roll about a bit, your temperature will drop slightly, your muscles will relax, and your breathing were slow and become quite regular. Your brain waves slow down a bit too, with the alpha rhythm of rather fast waves predominating for the first few minutes. This is called stage 1 sleep. For the next half hour or so, as you relax more and more, you will drift down through stage 2 and stage 3 sleep. The lower your stage of sleep, the slower your brain waves will be. Then about 40 to 60 minutes after you lose consciousness you will have reached the deepest sleep of all. Your brain waves will show the large slow waves that are known as the delta rhythm. This is stage 4 sleep.
