Every day, life is made and lost. Every day, life goes on. Every day we experience some of the most important parts of life and may not even realize it: love, generosity, and perseverance. These values aren’t just important to us, they make the world what it is.

Scientists say that the gravity makes the world turn, but some people say that love makes  it  go around. Love can be found anywhere: in families, friends, even strangers. Even if you can’t see it, you know it’s there.

Love may connect people all over the world, but what would the world be without generosity? Whether after a national disaster or a school fund raiser, one thing is certain--- it is better to give than to receive. Generosity is found everywhere and whether it’s a large or small act, it makes a difference. Most of all, generosity is not something you need any qualifications（资格）for, and no matter what you do, it can make a difference. Sometimes, though, it takes effort to be generous, which leads us to perseverance.

Founding a country, riding a bike, or finishing a novel, these are all finished with perseverance. Perseverance is the one thing that can help us achieve whatever we want. It is what helps scientists discover cures for illnesses, and athletes become winners. You may fail, but every time you make a mistake, that’s one less to make the next time.

There is an infinite(无限的) number of things we value. But without love, generosity, and perseverance, we just don’t think that our lives or the world would be the way it is.

地球的海水总量约有1.4×10¹⁸ t，是人类最大的资源库

（1）如图利用海水得到淡水的方法为________。

（2）电渗析法是近年发展起来的一种较好的海水淡化技术，其原理如图：

a是电源的________极；I口排出的是________（填“淡水”或“浓水”）。

（3）海水淡化后的浓水中含大量盐分，排入水中会改变水质，排到土壤中会导致土壤盐碱化，故不能直接排放，可以与氯碱工业联产。

①电解前需要把浓水精制，加入试剂的顺序为___________________________________；

②用离子交换膜电解槽电解食盐水的化学方程式为

_________________________________________________________________________________________________________________________________。

（4）铀是核反应最重要的燃料，其提炼技术直接关系着一个国家核工业或核武器的发展水平，海水中铀以UCl₄形式存在，每吨海水只含3.3 mg铀，海水总量极大，铀总量相当巨大。不少国家正在探索海水提铀的方法。现在，已经研制成功了一种螯合型离子交换树脂，它专门吸附海水中的铀，而不吸附其他元素。其反应原理为________（树脂用HR代替），发生离子交换后的离子交换膜用酸处理还可再生并得到含铀的溶液，其反应原理为_______________________________________________________________________________________________________________________________。
