某班有些同学上课爱说闲话，老师讲到关键地方时也如此。班主任多次严厉批评，可还有几位同学不以为然，说：“上课说几句闲话有啥呢？小题大做！”为此，班主任决定召开班会，让大家充分讨论，帮助这几位同学尽快改正。

如果你要在班会上发言，你如何评析这几位同学的看法？

   Danny was just tired about the way things were going. His mum came to school and talked on and on about Rick Jackson. It seemed that she would never stop talking. “Somebody’s got to stop that boy!” she was shouting. “Rick’s troubling everybody in the neighborhood. And he loves to pick on little boys like Danny.”
   Mrs. Green, Danny’s teacher, was concerned a lot. “I didn’t know that Danny was being picked on,” she said. “He’s never said anything about this to me!” Mrs. Green looked at Danny. “How long had this been going on?” she asked. Danny could only shake his head and look at the floor. He knew if he said a word about this, he would have trouble at school.
   Danny hadn’t said anything about the problem because he wanted to do things with the boys in the neighborhood. After all, most of them were nice to him. He hated to leave the gang just because of Rick. Maybe the time had come to find new friends. He felt it hard to make up his mind.

中国是历史悠久的文明古国之一，与世界其他文明相比，中国历史记载最为完整，历史遗存最为丰富。今天，我们就进行一次“远古祖先的拜访”活动，请你按要求完成下列探究任务。

材料：在北京人居住的岩洞里，科学家们所获的大量化石和石器，为古人类研究提供了丰富的、价值极高的研究资料，因而有助于我们较为清楚地了解北京人的劳动和生活。

问题一 ：结合上述图文材料和所学知识，分别从衣、食、住、用火、使用工具、人与人的关系等多角度举例说明北京人是怎样向现代人进化的。

问题二：河姆渡和半坡遗址是我国原始农耕时代的典型代表，通过考古发现，我们知道了这两种不同风格的农耕文化，原始农耕文化的产生是人类发展史上的重要里程碑。请你结合具体史实，举例说明这两种文化的不同点及原因。
