Why Do People Shrink？
Did you ever see the movie Honey, I shrunk the kids？ It's about a wacky(古怪的)dad (who's also a scientist) who accidentally(偶然的) shrink's his kids with his homemade miniaturizing (使小型化) invention. Oops! The kids spend the rest of the movie as tiny people who are barely visible while trying to get back to their normal size.
(46) It takes place over years and may add up to only one inch or so off of their adult height (maybe a little more, maybe less), and this kind of shrinking can*t be magically reversed, although there are things that can be done to stop it or slow it down. But why does shrinking happen at all？
(47) As people get older, they generally lose some muscle and fat from their bodies as part of the natural aging process. Gravity (the force that keeps your feet on the ground) take hold, and the bones in the spine, called vertebrae(椎骨), may break down or degenerate, and start to collapse into one another. (48) . But perhaps the most common reason why some older people shrink is because of osteoporosis (骨质疏松症).
Osteoporosis occurs when too much spongy(海绵) bone tissue (which is found inside of most bones) is broken down and not enough new bone material is made. (49) . Bones become smaller and weaker and can easily break if someone with osteoporosis is injured. Older people—especially women, who generally have smaller and lighter bones to begin with—are more likely to develop osteoporosis. As years go by, a person with osteoporosis shrinks a little bit.
Did you know that every day you do a shrinking act？ You aren't as tall at the end of the day as you are at the beginning. (50) . Don't worry, though. Once you get a good night's rest, your body recovers, and the next morning, you're standing tall again.
A. They end up pressing closer together, which makes a person lose a little height and become shorter.
B. That's because as the day goes on, water in the disks of the spine gets compressed (squeezed) due to gravity, making you just a tiny bit shorter.
C. Over time, bone is said to be lost because it's not being replaced.
D. Luckily, there are things that people can do to prevent shrinking.
E. For older people, shrinking isn't that dramatic or sudden at all.
F. There are a few reasons.

Are you superstitious？ No, of course not. Do you believe in magic (魔法), and luck charms (护身符), and elves or gremlins (小精灵) ？ Certainly not, but if I should greet you with the usual How's business？" You'll answer "Oh, just so-so" although your business is profiting greatly. When you are successful in some venture you might say you were just lucky. And yet, you know it was probably due to your a bility and hard work. Why？ Sometimes you knock on wood because wood was once a tree and there is a primitive belief that protective gods inhabit trees and knocking on wood attracts their attention so they may be credited with your successes.
If I should sneeze, only the strongest of you could refrain(克制而不) from saying "God bless you". Why bless this unsanitary (不讲究卫生的) habit？ Our ancestors believed that a sneeze opened the body to invasion by devils, and invoking (召唤) the name of God made the devils get out in a hurry. You may not realize it, but you express this same "devil invasion" when you say, "Whatever can have gotten into that child？" or "I wonder what possessed me to do that？"
Although they may no longer be believed, evidences of superstitions that have had their origins in the primitive fear of the unknown still exist in modern language and gestures.
The author ______.
A．believe that most people are superstitious
B．believe that very few people are superstitious
C．believes that there are still some evidences of superstitions in what we say and what we do

Thirty- two people watched Kitty' Genovese being killed right beneath their windows. She was their neighbor. Yet none of them helped her. Not one even called the police. Was this gunman cruelty？ Was it lack of feeling about one' s fellow man？
"Not so," say scientists John Barley and Bib Fatane. These men went beyond the headlines to probe the masons why people didn't act. They found that a person has to go through two steps before he can help. First he has to notice that is an emergency. Suppose you see a middle - aged man fall to the side - walk. Is he having a heart attack？ Is he in a coma (昏迷) from diabetes(糖尿病) ？ Or is he about to sleep off a drunk？ Is the smoke coming into the room from a leak in the air conditioning？ Is it "steam pipes" ？ Or is it really smoke from a fire？ It' s not always easy to tell if you are faced with a real emergency.
Second, and more important, the person faced with an emergency must feel personally responsible. He must feel that he must help, or the person won' t get the help he needs. The researchers found that a lot depends on how many people are around. They had college students in to be "tested". Some came alone. Some came with one or two others. And some came in large groups. The receptionist started them off on the "tests". Then she went into the next room. A curtain divided the "testing room" and the room into which she went. Soon the students heard a scream, the noise of file cabinets falling and a cry for help. All of these had been pre - recorded on a tape - recorder. Eight out of ten of the students taking the test alone acted to help. Of the students in pairs, only two out of ten helped. Of the students in groups, none helped.
In other words, in a group, Americans often fail to act. They feel that others will act. They, themselves, needn't. They do not feel any direct responsibility. Are people bothered by situations where people are in trouble？ Yes. Scientists found that the people were emotional, they sweated, they had trembling hands. They felt the other person's trouble. But they did not act. They were in a group. Their actions, were shaped by the actions of those they were with.
31. The purpose of this passage is______.
A) to explain why people fail to act in emergencies
B) to explain when people will act in emergencies
C) to explain what people will do in emergencies
D) to explain how people feel in emergencies
