题型:阅读理解

问题:

Playing is serious business for children. In fact, it’s what they do best! Ask them why they do it, and kids will probably say, “Because it’s fun!” But it’s much more than that. It’s also good for them.

Studies show that from birth babies begin learning through playing. They use their five senses to get to know their new world. Touching allows them to discover how different things feel. Brightly colored toys and clothing help develop a baby’s sense of sight.

When small children choose which toy to play with, they begin developing their abilities in making decisions. Children love toys that allow them to use their imagination. Sometimes an empty box is more fun than a high-tech toy. That’s because a box can become anything a child imagines it to be.

Crayons, paints and Ply-Doh(彩色塑泥)are also good because they allow children to create. Traditional building blocks teach important pre-math skills like problem-solving.

Playing doesn’t become any less important once children start school. _____. Kids learn how to share, take turns and play by the rules.

Na2O2是中学化学常用的强氧化剂,除了能与CO2、H2O反应外,还可与其他还原剂如H2、C发生反应,某化学课外兴趣小组为探究Na2O2与H2的反应情况,设计了如图所示装置进行有关实验。

(1)实验前,装置的气密性检验方法是                                       

(2)该装置中,碱石灰的作用是               ;实验开始时,先打开a、b产生氢气,一段时间后,再点燃酒精灯加热,目的是                           

(3)在启普发生器中,下列做法可以加快生成氢气速率的有           

A.滴加少量的硫酸铜溶液                                      B.铁粒改用相同量的铁粉           C.稀盐酸改为浓度为其2倍的稀硝酸            D.适当加热          

(4)若实验过程中观察到淡黄色粉末变成白色,干燥管内硫酸铜变成蓝色。则Na2O2与H2反应的化学方程式为                                       

(5)实际实验过程中观察到Na2O2熔化后,很快变成白色粉末,但干燥管内硫酸铜并未变成蓝色。则Na2O2与H2反应的化学方程式为                                 

(6)出于实验安全考虑,实验结束时            

A.应先关闭活塞b,然后移去酒精灯

阅读下列材料

材料1  300年前,17世纪末,中国的康熙皇帝和俄国的彼得大帝善于吸收新鲜知识,康熙还向洋教士学证几何题;两个皇帝都锐意改革,康熙兴修水利,发展农业,改革税制,力度不可谓不大,也开创了“康乾盛世”,取得不少成绩。然而,俄国改革的效果却远远超过中国。

材料2  300年前,我们曾经有过惨痛的历史教训,康熙对当时的工业化萌芽不感兴趣。150年后,在新的海上航路使世界地域一体化进程中,1840年西方的工业经济产物——坚船利炮彻底打垮了中国小农经济大刀长矛,其实直到1860年中国和印度还分别居世界工业总产量(以手工业产量为主)的第一和第二位。—《21世纪社会的新趋势——知识经济》

回答:

(1)“康乾盛世”的繁荣是建立在什么经济基础上的?

(2)18世纪中后期西方国家的经济发生了什么变化?

(3)中国封建政府对萌芽状态中的资本主义采取什么政策?

(4)其影响如何?

(5)试以生产力和生产关系的原理分析中国、印度等国落后挨打、世界出现“东方从属于西方”局面的原因。
