近代社会的民主思想与实践

材料：辛亥革命推翻清王朝的过程似乎是容易些了，更多的困难留给了革命之后。由于清王朝不是由长期的剧烈革命斗争推翻的，因此也就没有为革命派在战争中创建一支坚固而强大的军队创造条件。在当时，虽然在一些地方，特别是在南方的一些省份，独霸一方的实力派们曾纷纷站到革命一边，但对于手中没有什么实力的南京临时政府来说，要控制和指挥这些军事力量是相当困难的。孙中山个人的威望和影响是形成临时政府权威基础的一个重要因素，但“轻而易举”的革命无法为形成这样的领袖提供舞台。因此，利用领袖个人感召方来建立南京临时政府权威基础的条件并不充分。在上述条件下，南京临时政府只维持几十天，就不得不将权力移交给袁世凯，这就毫不奇怪了。

根据短文内容，完成下列各题。

      Grace was fourteen years old and was in Grade Eight. She had a part-time job, so she had to get up at five o'clock. She was a newspaper girl.

      Each morning, Grace left the house at 5:15. She always rode a bike to the corner to carry the newspapers.

      In winter it was still dark when she got up, but during the rest of the day it was bright. Grace had to send newspapers to people's houses in all kinds of weather. She tried to put each paper in the box where it would be kept safe from wind, rain or snow. Her customers thought she did a good job. Sometimes they gave her tips(小费).

      Grace made about $70 each month and she was saving some of the money to go to college. She spent the rest on tapes and clothes. Once a month she got the money from her customers together. Since many of them worked during the day, Grace had to get the money at night. Sometimes when Grace was ill, her elder brother had to send the newspapers and Grace's father had to help her.

      Grace had 70 customers now, but she hoped to get more later. Some day, if she got more customers, perhaps Grace could win a prize for being a very good newspaper girl. She wanted to win a visit to Europe, but she would be happy if she won a new bike.
