假设你叫陈军，昨天收到了笔友David的e-mail，得知他不久要作为交流生到泰兴来学习中文。他想了解如何学好中文。请你用英文给他回复一封e-mail，介绍学习中文的体会和方法，提出你的建议，以及表达你帮助他学好中文的愿望。
要点提示：
汉语非常有用，现在许多外国朋友都在学习。
汉语较难，因为它跟英语很不一样。
必须尽量多记词，读和写也很重要。
可以通过看电视和听广播锻炼听力。
其他的方法……
注意：
1. 语法正确，意思连贯，书写规范，要点齐全；
2. 第五要点须用1至2句话作适当的发挥；
3. 词数80字左右。信的开头和结尾已给出，不计入总词数。

实验步骤如下：①切取一小块金属钠，用滤纸完全吸干煤油，再除去表面的氧化层，放进干燥的E中；
②打开分液漏斗的活塞，使B中的反应进行一段时间后，再点燃E处的酒精灯。
实验现象如下：钠在充满C02气体的玻璃管中剧烈燃烧起来，产生大量的白烟；玻璃管中有黑色物质生成；待玻璃管冷却后，管壁上附着一层白色物质。
请回答下列问题：
（1）C中盛放的试剂是 ，作用是 。D中盛放的试剂是 ，作用是 。
（2）B中的反应进行一段时间后，再点燃E处的酒精灯的目的是 。
（3）该同学将白色物质和黑色物质分别溶于水，发现黑色物质不溶于水，白色物质能溶于水。由此，该同学得出结论，该黑色物质是Na与C02反应生成的碳单质，则其他生成物还应该有 。
（4）请设计一实验方案验证玻璃管内Na与C02反应生成的白色物质的成分，并写出实验步骤、现象和结论 。
（5）若先点燃E处的酒精灯，再打开分液漏斗的活塞，写出此时玻璃管E中可能发生的反应的化学方程式 。 查看习题详情和答案>>
