The back door of the ambulance (救护车) was suddenly shut and the driver ran to the front, jumped into the seat, and started the engine. Inside were the 　36　 parents, Mr. and Mrs. Green, the mother holding their baby daughter, Ally. The little girl had some food stuck in her 　37　and could hardly 　38　.?

On Wednesday afternoon Annie took the bus into town to shop in the market. For an hour or so she would walk up and down between the stalls looking at everything, buying here and there, and   1  a sharp lookout for the bargains that were something to be haD．And then, with all the   2  she needs bought she would leave the market for the   3  of the town to spend another hour   4  she liked best, looking in furniture-shop windows.

One Wednesday she found a  5  shop full of the most delightful things, with a   6  inviting anyone to walk in and look round without   7  they had to buy something. Annie hesitated a moment   8  stepping through the doorway where, almost at once, she stopped   9  before a green armchair. There was a card on the chair which  10  ,“This fine chair is yours for less than a pound a week,” and very small at the bottom, “Cash price eighty-nine pounds fifty.” A pound a week …Why, she could almost pay that out of her housekeeping money and never   11  it!

A voice at her shoulder made her   12  .“Can I help you, Madam?” She looked   13  at the assistant who had come softly to her  14 

“Oh, well, no,” she said, “I was just   15  .”

“We have chairs of all kinds in the   16  . If you'll just come up, you will find something to  17  you.”

Thirty-two people watched kitty Genovese being killed right beneath their windows. She was their neighbor. Yet none of the 32 helped her. Not one even called the police. Was this in 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（探查） the reasons 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(紧急情况).

　　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 this 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.
