完形填空
He met her at a party. She was outstanding; many guys were   36  her, but nobody paid any attention to him. After the party, he invited her for coffee. She was surprised. In order not to appear   37 , she went along.
  As they sat in a nice coffee shop, he was too   38  to say anything and she felt uncomfortable. Suddenly, he asked the waiter, "Could you please give me some   39 ? I'd like to put it in my coffee."
  They stared at him. He turned   40 , but when the salt came, he put it in his coffee and drank.   41 , she asked, "Why salt with coffee?" He explained, "When I was a little boy, I lived near the sea. I liked playing on the sea ... I could feel its taste salty, like salty coffee. Now  42  I drink it, I think of my childhood and my hometown. I   43  it and my parents, who are still there."
  She was deeply touched. A man who can admit that he's homesick must love his home and   44  his family. He must be responsible.
  She talked too, about her faraway hometown, her childhood, her family. That was the start to their love story.
  They continued to   45 . She found that he met all her   46 . He was tolerant, kind, warm and careful. She would have missed the catch if not for the salty coffee!
  So they   47  and lived happily together. And every time she made   48  for him, she put in some salt, the way he liked it.
  After 40 years, he passed away and left her a letter which said:
  My dearest, please   49  my life-long lie. Remember the first time we dated? I was so nervous I asked for salt instead of   50 .
  It was hard for me to ask for a   51 , so I just went ahead. Many times, I tried to tell you the truth, but I was afraid that it would   52  everything.
Sweetheart, I don't exactly like salty coffee. But as it   53  so much to you, I've learnt to enjoy it. Having you   54  me was my greatest happiness. If I could live a second time, I hope we can be together again,   55  it means that I have to drink salty coffee for the rest of my life.
