中国传统文化中的辩证法思想，历久而弥新，不朽而璀璨。下列选项蕴含“矛盾是事物变化发展的动力和源泉”的是（ ）
A．和实生物，同则不继
B．世异则事异，事异则备变
C．金元足赤，人无完人
D．知是行之始，行是知之成
答案：A
题目分析：A项中“和实生物，同则不继”，意为只有参差不齐，各不相同的东西，才能取长补短，产生新的事物，而完全相同的东西聚在一起，则只能永远停留于原有的状态，不可能继续发展，体现了矛盾是事物变化发展的动力和源泉，符合题意，可以入选；B项中“世异则事异，事异则备变”，强调的是事物是运动变化和发展的，不合题意，故不能入选；C项中“金元足赤，人无完人”，强调的是要坚持用全面的观点看问题，不合题意，故不能入选； D项中“知是行之始，行是知之成”，错误的表达的实践与认识的关系，属于主观唯心主义的观点，不合题意，故不能入选。因此，答案是A项。

| About a week ago, when I was playing basketball at our local park, I noticed a small group of boys picking on a smaller, skinnier boy. They were 1 him names and even pushed him to the ground and kicked dirt in his face. 2 I saw that, I walked over to the group. I stepped 3 them and the smaller boy, and asked them politely what this boy had done worthy of 4 they were doing to him. One of the boys replied, "He's weird." At that, I asked one of the boys if he thought his friend was weird, and the 5 was "No." So, I asked another boy what the word "weird" 6 , and he said, "Different." That was my cue (暗示). I told them that everyone is 7 , and that they all looked just as different to the other boy as he did to them. They all stood 8 for a moment, and then the most amazing thing happened. One of the boys helped the small boy off the ground and then said sorry to him. He 9 to let him play with them. I thanked the boy for being so 10 . As I looked around, I realized that there were dozens of other people at the park 11 no one else had stopped to help this boy. I felt happy that the boy was strong enough to stand up against his friends to 12 someone in need, but I felt sad that 13 else had even taken a second look. I hope that my action helped them 14 that they could have made a difference with a little 15 , and maybe next time they will be the ones who choose to help. | ||||
