近代著名社会活动家梁启超一生“有定则无定见无定行”。定则是爱国之心立宪之志和新民之道，在此定则下，其见解、行动则是不断流变的：维新—保皇—君主立宪—护法—民主共和。这一事例集中体现了（    ）

    Three years ago, I got to know a poor lady named Rose. She had no children and lived alone. When I went to visit her, I always took her some1and food. One day she asked me to have coffee and delicious food for lunch at a restaurant near her home.

    2the way, I began to worry: I knew that she had no money, but if I offered to3the lunch, I was afraid I must hurt her.

    There were many people in the4and all of them were happy. Rose told me to sit and drink coffee by the window. Then she went into the5. I didn't know what happened. After about 20 minutes, she came out with some food. Then we started to enjoy the delicious food together. She told me that the restaurant allowed people to work for a meal6they had no money. The restaurant also might give them a free meal if they were not7to work, especially for the disabled.

    I 8remember the beautiful afternoon I shared with Rose. We had a meal, and Rose paid for it by her work. The weather was9and bright, and everyone's smile was warm and bright as well.

    I'm still thinking that life cannot be easy to us, but we can still do something for our friends and other people. The world will be10if everybody would like to share happiness with others.
