     "High income is not as good as high age, and high age is not as good as high spirits."

     Generally speaking, the rich are happier because money can buy them goods and services and it is the

consumption (消费) of these materials that increases one's enjoyment of life. Especially nowadays, money

seems to be one thing that drives the people around. "Human beings live for money while birds die for food."

-a well-known Chinese saying is quite quotable (适宜引用的) to explain the present society. Some people try

every means to make money at the cost of others' interests. These people harm others to benefit themselves.

They think the more money they make, the happier they will be.

     In addition to money, people's happiness was affected by other factors. High age is what many Chinese

are dreaming of. Longevity is the very term that people often use to pray for their dears and elders. So there

are many books and theories that introduce the way of living longer. Dancing, jogging, dieting, even singing

and shouting together are said to do good to one's health.

     However, some people think that high spirits is the most important to the quality of one's life. If you are

in high spirits, you'll find everything pleasing and comfortable in life: warm sunshine, blue sky, white clouds,

happy birds, comfortable breeze (gentle wind), sweet smiles, and so on. You seem to have friends across the

world. Your life will be happy at every moment. You will be in good health and can make more money if you

live longer.

     In one word, let's keep ourselves in high spirits, therefore we could keep longevity and make considerable

money at the same time.

多项选择题
实验题

农用的氮肥主要是“氢铵”和尿素。某化学兴趣小组对某“氢铵”化肥进行了专项研究: (1)预测:根据已有知识和“氢铵”的名称,该小组预测该“氢铵”是碳酸或亚硫酸或硫酸的铵盐。

验证和探究:

①NH4+的验证:取少量固体药品于试管中,然后______________

②阴离子的探究:a.取少量固体药品于试管中,然后向试管中滴加稀盐酸,固体全部溶解,将产生的气体通入如图装置中。观察到的现象是:溴水无明显变化,澄清石灰水变浑浊。再向滴加稀盐酸反应后的试管中,加Ba(OH)2溶液,无明显现象。初步结论:“氢铵”是____的铵盐。

b.要进一步确定“氢铵”的成分还需要补做如下实验并根据现象作出相应分析:取适量“氢铵”配制成溶液,取溶液于一支洁净的试管中,加_________________

(2)该实验小组设计了以下两个实验方案测定该化肥的含氮量,请你阅读后解释方案中提出的问题并进行评价:

方案(一):准确称取一定质量的样品,放入如图甲的烧瓶中,滴加过量NaOH浓溶液,充分微热,按如图装置,通过实验测定烧杯增加的质量(忽略漏斗中附着溶液的质量)。然后进行计算,可得化肥的含氮量。

方案(二):准确称取一定质量的样品,放入如图乙的烧瓶中,滴加过量NaOH浓溶液,充分微热,按如图装置(A管可以上下移动),测量生成的氨气体积(设所测体积为标准状况下的体积)。然后进行计算,可得化肥的含氮量。图乙中导管a的作用是___________ 请你评价上述两套方案是否合理。若合理只需要说明结论;若不合理,请简要说明原因,并指出修改方案(若要添加仪器、药品,请说明添加的位置、名称)。

方案(一):________________________;

方案(二):________________________。
