万用表测量时应注意的事项有哪些？

2008年12月6日，法国总统不顾中国的坚决反对，悍然与达赖会面，再次激起中国人民的强烈民族意识。材料告诉我们，弘扬民族精神是

A．提高全民族素质的必然要求

B．不断增强我国国际竞争力的要求

C．坚持社会主义道路的需要

D．保持党的先进性的根本要求

材料一：2009年9月27日，国务院出台《文化产业振兴规划》。规划指出，文化产业是市场经济条件下繁荣发展社会主义文化的重要载体。在当前应对国际金融危机的新形势下，加快振兴文化产业，对于满足人民群众精神文化需求，扩大内需，推动经济结构调整，具有特殊意义。

材料二：当《哈利·波特》、《追风筝的人》等海外图书风靡中国的时候，中国图书的海外之行却步履维艰。被认为是中国最成功的海外营销图书《狼图腾》，其英文版权仅仅卖了10万美元；中国创造销售奇迹的《于丹〈论语心得〉》在海外同样遭遇滑铁卢。这主要是因为中国图书历史题材多、当代题材少，缺乏优秀的原创作品。

运用所学知识，回答以下问题：

（1）结合上述材料，运用文化生活的有关知识，谈谈我们如何推动中华文化走向世界？（10分）

（2）有人认为，当前国际竞争的实质就是文化产业的竞争。运用政治生活的有关知识分析该观点。（7分）

（3）结合材料一，简析振兴文化产业的辩证法依据。（8分）

某部分变质的NaOH试剂经处理后只含有NaOH和Na₂CO₃两种物质。小明同学从中均匀取出9.3g样品用19.9g水溶解后，再向其中缓慢滴加10%的稀盐酸至恰好完全反应时，用去稀盐酸73g，经测定共放出气体2.2g。

（1）向样品中加入稀盐酸至恰好完全反应时，发生的两个反应可用化学方程式表示为：

_______________________________________，_______________________________________；

9.3g样品中，含Na₂CO₃的质量为_____________g，含NaOH的质量为_____________g。

（2）通过计算确定原NaOH试剂的变质程度。（用质量百分数表示）

（3）上述恰好完全反应后的溶液中，溶质的质量分数是多少？（用百分数表示，保留一位小数）

情景交际

    Recently some American scientists have given a useful piece of advice to people in industrialized nations.

They say people should eat more of the same kind of food eaten by humans living more than 10,000 years

ago.1.________

     The scientists say that the human life has changed greatly.Our bodies have not been able to deal with

these changes in lifestyle and this had led to new kinds of sicknesses.2.________So they are called

"diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

     Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little

alcohol or tobacco,probably none.3.________However,a change in food is one of the main differences

between life in ancient times and that of today.

     Stone Age people hunted wild animals for their meat,which had much less fat than domestic ones.They

ate a lot of fresh wild vegetables and fruits.They did not have milk or any other dairy products,and they

made very little use of grains.4.________We eat six times more salt than our ancestors.We eat more

sugar.We eat twice as much fat but only one third as much protein and much less vitamin C.

     5．________But scientists say that we would be much healthier if we eat much the same way the

ancient people did,cutting the amount of fatty,salty and sweet food.

A．Stone Age people lived a simple life.

B．But today,we enjoy eating a lot of these.

C．In that case,they would live much healthier.

D．Ancient people also got lots of physical exercise.

E．These new sicknesses were not known in ancient times.

F．People today probably don't want to live like our ancestors.

G．Modern people used to suffer from "diseases of civilization"．
