Several years ago，I was at a train station in Amsterdam. I saw a young homeless man _______ people for money so he could buy breakfast . Most of the _______ simply took no notice of the young man or gave him a dirty look. There was one exception（例外）though：an older，well-dressed lady. When the young homeless man moved _______ this elegant lady，she turned and looked straight into his eyes and _______ asked，“How much do you need？”I couldn't hear what the young man said but watched _______ the lady pulled several bills（纸币）from her wallet and _______ them in the young man's hands.

I don't know whether the young man actually used this money for breakfast or for some other purposes. What I do know is that I saw two completely different reactions（反应）to the same _______. I saw people who were _______ afraid or annoyed or distrustful（猜疑的）. And then I saw this old lady who _______ the homeless man as her brother.

Every day may bring us many chances for __________. The key is to do it or not.
