完形填空。
     My elder sister Lisa is only four feet ten, but she has a great personality. I learned everything about
   1   from her. She is  2  a brilliant businesswoman. Once she ran nine   3  at the same time just by
herself.   4   she talked to her employees, she'd stand on a box. Thus she could look them straight in the
eye and  5    connect with them.
     These days I work in my sister's restaurant. Of course, we quarrel with each other   6  , but I think
it's    7   to be open and honest and let things out.   8   God has given us all kinds of senses, we should
each have our own   9    and, of course, we can't always  10   with others.
     One day a woman  11  Vicky was helping me prepare a salad for a cooking class. "You forgot sugar
and vinegar," Vicky pointed   12  . "They're used in most salad cookbooks."
    I   13  to her, "In my family, we don't  14    sugar and vinegar to our salad" She argued,"We do in my
family, and our salad is very good."
    "Yeah? Well,  15   is great!" I shouted back.
    Back and forth we went   16   we both burst into tears. What are you doing? I asked myself. You
became so angry just  17   a recipe! Then I hugged Vicky 18    and she hugged me right back. We've
been best friends ever since. 
    Be real; Make   19  with people; Look them in the eye; Tell them how you feel;  Don't be afraid to
say  20  you mean. When you let go of the feelings you hold inside, you'll be amazed at what comes back
to you.
