You’re rushing to work and a man ahead of you collapses on the sidewalk. Do you stop to help？ In a study of by-standers, it was found that some people avert their gaze and keep on  walking rather than stop and get involved. “There is a tendency to decide that no action is needed.” says a psychologist. “The first thoughts that pop into your mind often keep you from offering help. In order to take action, you have to work against them.” Here are some common thoughts that might prevent you from helping. ● Why should I be the one？ I’m probably not the most competent person in this crowd. You might think someone older or with more medical knowledge should offer assistance. ● What if he doesn’t really need my help？ The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others. ● No one else looks concerned- this must not be a problem. We can follow the people around us, but most people tend to hold back their emotions in public. “If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on,” says the psychologist. “Then retry to involve other people; you don’t have to take on the entire responsibility of being helpful. Sometimes it’s just a matter of turning to the person next to you and saying, ‘It looks like we should do something.’ Or asking someone if an ambulance has been called and, if not, to call for one.

My mother seemed to be able to make dolls （洋娃娃) out of anything. She made some dolls for me and my two elder sisters. I 36 playing with them, but still, secretly, I hoped for a store-bought 37 like the one our rich cousin had. Her doll 38 open and close its blue glass eyes and even say "Mamma". I 39 stopped admiring it and hoping to have one.
However, my dream 40 came true when I was six. One day my father came back from his business trip with three 41 dolls! They were much smaller than our cousin’s doll and their eyes were just painted ones, but I did not 42 such differences. They were 43 "store-bought" dolls. We each chose one and I named 44 Misako.
Soon my sisters and I became 45. Our "children" kept us 46 all day. We gave them a bath, 47 them, brushed their hair, took them out for a walk and put them to bed. Several months later, they got more like real children — their 48 and bodies became dirtier; their dresses got stained; their hair less smooth.
But, by then, 49 interests seemed to have moved into 50 toys. Their dolls were abandoned （被抛弃) and in bad condition. One had 51 one of her arms, and 52 was one-legged. "You can 53 them if you want," my sisters said to me. Thus, I had 54_ dolls. They were more or less handicapped （残疾) and they often looked at me as if they needed me to 55 them. I enjoyed this feeling of being needed — being the only one in the world who could protect them with a lot of love. Indeed, they made the rest of my childhood days very happy.
