    Several times my daughter had telephoned to say, “Mum, you must come and see the daffodils(水仙花)before they are over.” I wanted to go, but it was a two-hour drive from Lake Arrowhead. "I will go next Tuesday," I promised, a little unwillingly, on her third call.

    The next Tuesday dawned cold and rainy. Still, I had promised, and so I drove there. When I finally walked into Carolyn's house and hugged and greeted my grandchildren, I said, "Forget the daffodils, Carolyn! The road is invisible (看不见的) in the cloud and fog, and there is nothing in the world except you and these children that I want to see!"

    My daughter smiled calmly and said, "We drive in this weather all the time, Mum. You will never forgive yourself if you miss this experience."

    After about twenty minutes, we turned onto a small road and I saw a small church. On the far side of the church, I saw a hand-lettered sign that read "Daffodil Garden."

    We got out of the car and each took a child's hand, and I followed Carolyn down the path. Then, we turned a corner of the path, and I looked up amazed. Before me lay the most beautiful sight. Flows of flowers of different colors seemed poured down the peak and slopes. There were five acres of flowers! A sea of daffodil! It was like a fairyland all beyond description.

    "But who has done this?" I asked Carolyn. "It's just one woman." Carolyn answered. "That's her home." Carolyn pointed to a well-kept A-frame house that looked small and modest in the midst of all that glory. We walked up to the house. On the patio (露台), we saw a poster." Answers to the Questions I Know You Are Asking" was the headline.

    The first answer was a simple one. "50,000 bulbs (鳞茎)" it read. The second answer was, "One at a time, by one woman." The third answer was, "Began in 1958."

    I thought of this woman whom I had never met, who, more than fifty years before, had begun one bulb at a time to bring the beauty and joy to the mountain top. Just planting one bulb at a time, year after year, had changed the world where she lived and created something of magnificence, beauty, and inspiration.

    When we multiply tiny pieces of time with small amounts of daily effort, we too can accomplish great things. Everyone can do something to change the world.

    In our country we think being modest(谦虚的) is a virtue(美德) and being proud is a bad thing. One day, I heard an American boy say to a Chinese student, “You speak very good English.” But the girl answered, “No, no. My English is very poor.” The foreigner was quite 1 at the answer. Thinking he had not made himself understood or the girl had not heard him 2. He said, “Yes, indeed, you speak very well.” 3 the girl still kept saying, “No.” In the end the American boy could not understand and didn't know 4 to say.

    What's wrong with the girl's answer? She didn't 5 a compliment(恭维) in the same way as the American people do. She should answer “Thank you” instead of “No”. She 6 understood what the American boy had said, but she thought she should be modest. In the 7, people will feel 8 and confident when they are praised. So if someone says the 9 you have cooked are very delicious, you should say, “Thank you”.

    If you are modest and say, “No, I'm 10 I can't do it well”, while working in a western country, people may think that you really can not do it. If you often say, “No”, you'll certainly be looked down upon by 11. When asking 12 a job, if one says something like, “Yes, I can certainly do it” instead of “Let me have a try”, he or she will 13 get it. So in the west, you should be brave to show your self-confidence. In my opinion, being confident does not 14 being proud, so sometimes you should be confident 15 being modest.
