一大杯牛奶的故事 

       一个出身贫苦的男孩，为了积攒学费而换家挨户地推销商品。     

       这天傍晚，他奔走了一整天，又累又渴又饿，可身上只剩下一毛钱。他决定向下一户人家讨一口饭吃。     

       可是，当一位天使似的姑娘打开大门时，他却有点不知所措了。他不好意思张口要饭吃，只求姑娘给他一口水喝。     

       姑娘看出他的疲惫和饥饿，微笑着给了他满满一大杯牛奶。男孩饥不择食地喝完牛奶，嗫嚅地说： “我应该付您多少钱？”     

       姑娘仍旧微笑着对他说：“您不用付钱。 妈妈经常教导我们：施以爱心，不图回报。”    

       泪水涌上男孩的眼眶，他轻轻地说：“那么，就请您接受我由衷的感谢吧！”     

       其实，男孩本来是打算退学的。如今，他仿佛看到上帝在朝他点头微笑，他觉得浑身有劲，男子汉的豪气又迸发出来了。    

       若干年之后，有一位来自小城镇的姑娘得了一种罕见的重病。当地的医生束手无策，只好把她送到大城市去，请专家会诊治疗。     

       一位有名的医生参加了会诊。当他看到病历上记载的家庭地址时，他马上直奔病房。来到病床前，他一眼就认出了：这位病人就是当年送过满满一大杯牛奶给他喝的天使。他回到办公室，决心竭尽所能，回报这位“施以爱心，不图回报”的姑娘。     

       经过艰辛的努力，手术成功了，姑娘渐渐康复。这位医生要求医院把账单送到他的办公室，他付清了一切费用，并微笑着签上了自己的名字。  

       姑娘坚持要知道她应该支付多少医药费。 可是，当账单送到她的手上时，她又不敢看， 因为她确信：这笔费用将会花去她所有的积蓄，或许，还不够。最后，她还是鼓起了勇气，颤抖着翻开了这沓厚厚的账单。末尾的签字锁定了她的目光，她不禁轻声读了出来：     

      “医药费——满满一大杯牛奶霍华德·凯利医生”。 

1．结合上下文解释成语的含义。   

不知所措：                                                                              

2．“满满一大杯牛奶”产生不了多少热量，可它却能让男孩“觉得浑身有劲”，打消退学的想法并走向成功，其原因是什么？

3．短文中多处运用照应的写法，请你至少举出两处，并写出这样写的好处。

照应之一：                                                                                                                  

照应之二：                                                                                                                  

好处：                                                                                                                                   

4．这篇短文是精典之作，一直被人们传看，是因为他歌颂了什么品德？

5．对短文中的医生和姑娘你更喜欢哪一个，为什么？ 

6．中 * * 传统美德很重视感恩报德，你能举出一个有关成语（谚语、格言、诗句、故事）来吗？

The 92-year-old, thin, calm and proud lady, who is fully dressed each morning by eight o’clock, even though she is nearly blind, moved to a nursing home today.

Her husband of 70 years recently passed away, making the move necessary. After many hours of waiting patiently in the hall of the nursing home, she smiled sweetly when told her room was ready.

As she walked slowly to the elevator, I provided a true description of her tiny room, including the old sheets that had been hung on her window. “I love it,” she said with the happiness of an eight-year-old having just been presented with a new puppy.

“Mrs. Jones, you haven’t seen the room…just wait.”

“That doesn’t matter,” she replied. “Happiness is something you decide ahead of time. Whether I like my room or not doesn’t depend on how the furniture is arranged. It’s how I arranged my mind. I have already decided to love it. It’s a decision I make every morning when I wake up. Each day is a gift, and as long as my eyes open I’ll focus on the new day and all the happy memories I’ve stored away.” She went on to explain, “Old age is like a bank account. You take what you’ve put in. So, my advice to you would be to put in a lot of happiness in the bank account of memories. Thank you for your part in filling my memory bank.” And with a smile, she said, “All my memories are happy ones.”

Mrs. Jones was always happy in the nursing home and she died at the age of 108.
