痰饮的概念是什么?

答案

参考答案:

痰饮是机体水液代谢障碍所形成的病理产物。稠浊者为痰,清稀者为饮。痰饮又分有形之痰饮和无形之痰饮。有形之痰饮是指视之可见,触之可及,闻之有声者,如咳嗽之咯痰、喘息之痰鸣等;无形之痰饮是指视之不见,触之难及,闻之无声,但通过辨证求因,仍可确定为痰饮病证者,如头晕目眩、心悸、神昏等。

    I was in line waiting to pay. In line there were two people before me. A little boy was buying some

rather strange clothes. He chatted with anyone who was interested in the clothes and soon we learnt that

he was going to a kindergarten(幼儿园) party. He had done a great job of putting together interesting

costumes.

    I noticed that the little boy was paying mostly with change(零钱). It seemed that he had robbed his pig    bank(猪形储蓄罐) to do this shopping. However, the cashier told him he was short after counting  all

 the money. The boy thought for a moment  and said, "Please keep the shirt and I  will  come  back  with

 more money. "

    It was clear that he had already used all the money he had and he was $ 8.00 short. The lady in front of me said, "Well, I could pay half of  that. "I told the boy that  I could pay the other half. We  dug into our

handbags. However, both of us only had ten-dollar  bills(纸币)  and we  needed t he cashier to  get  the

change for us. Other shoppers began digging into their pockets to find some change. It was amazing and

touching as all these strangers seemed to react(反应) with the same mind. All wanted to be of help. Within minutes the cashier said, "I have too much money." The cashier didn't need our ten-dollar bills. Then the

lady in front of me, who had been the first to offer help, said, "Wait! I didn't even get a chance to give

anything!"

    I smiled at her and said, "You did your share, because it was your idea and you started all this. " The

little boy smiled and thanked us. We wished him the best and he left. I was left with a good feeling. I had

seen the love and goodness of others all around me. The woman in front of me smiled and said, "It sure

feels good to give, doesn't it?" I smiled back and said, "Yes !"
