Chinese are very generous in educating their children. Not caring about the money, parents often send their children to the best schools or even abroad to England, the United States and Australia. They also want their children to take extra-course activities such as musical instrument learning or ballet classes, or other classes. They think these will give them a good future. The Chinese believe that the more expensive an education is, the better it is. So parents will spend much unreasonable money on education. Even poor parents will buy a computer for their son or daughter.

However, most parents don’t understand that the best early education they can give their children is usually very cheap.

Parents can see that their children are very good in some areas while poor in others. Parents can also see some children are good at these skills and others do well in others. Most parents don’t realize that today’s children lack self-respect and self-confidence.

The problem is that parents are only educating their children on how to take tests and how to study well, but parents are not teaching them the most important skills that they need are to be confident, happy and clever.

Parents can achieve this by teaching skills like cooking, sewing and doing other housework. Teaching a child to cook will improve many of the skills that he will need later in life. Cooking needs patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and lots of self-confidence. 

Some old machines, such as a broken radio or TV set that you give your child to play with, will make him curious(好奇的) and improve his interest. He will spend hours looking at them, trying to fix them. Your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.

阅读材料,并回答问题                                                      

材料一 新中国成立之初,国家就开始推动农业机械化。2004年后,农业机械化得到迅猛发展。是年,国家出台了《农业机械化促进法》。此后历年中央“一号文件”都明确提出了相应要求和措施。中央财政农机具购置补贴资金从2004年的7000万元增长到2009年的130亿元。国家积极推动农业机械化中介服务组织发展,农机作业的订单服务、租赁服务、承包服务和跨区作业、集团承包等服务方式不断涌现,服务领域由粮食作物向经济作物,由种植业向养殖业、农产品加工业全面发展,由产中向产前、产后延伸。截至2008年底,我国农机总动力达8.22亿千瓦,是1949年的1万倍,初步构建起符合中国国情的农业机械化发展体系。

材料二 在市场竞争机制作用下,各种资源要素总是要向回报率比较高的区域或领域集中。在经济发展的某一阶段,各种资源要素向城市和工业流动具有必然性。但这一流向导致我国出现了城乡二元格局现象。2010年中央“一号文件”提出“推动资源要素向农村配置”,要求各部门各行业主动服务“三农”,在制定规划、安排项目、增加资金时切实向农村倾斜,大中城市要发挥对农村的辐射带动作用,以进一步夯实农业农村发展基础。

⑴结合材料一,运用经济知识简析我国在发展农业机械化的过程中是怎样做的。(10分)

⑵结合材料二,请从哲学角度分析国家作出“推动资源要素向农村配置”决策的依据。(10分)

2009年12月25日是西方传统的圣诞节,早在一个多月前我们就感受到浓浓的节日气氛,许多商家不仅用各种圣诞物装饰店面,而且还出售各种各样的圣诞礼品。更有一些商家打出了各种促销打折的广告,据说,市区某商场在24日平安夜人满为患,实现了上千万的销售额,直到凌晨3点左右才关门。面对着“扑面而来”的圣诞节,我们深刻地体会到了这一“洋节”的重大影响力。

⑴上述材料体现了哪些经济生活的道理。(10分)

⑵结合上述材料,从《文化生活》的角度,谈谈这一“洋节”有何重大影响力?(10分)

⑶文化的利益也是国家利益的重要组成部分。有人认为,“国家利益决定国际关系,任何国家都可以把国家利益放在首位,为维护本国利益可采取一切方式和手段”。运用政治生活的知识对该观点作出评价。(12分)
