稀土之王中国铁腕定夺


Hi, I'm Carl Azuz, and this is CNN Student News. Wanted to slice out a little time to wish everyone a happy Pie Day on this March 14th, 3-14 -- OK. Let's go ahead and get to today's headlines.

Two primaries, two caucuses, 110 delegates: that's what was at stake yesterday in the race for the Republican presidential nomination.

You know the candidates by now, former House Speaker Newt Gingrich, U.S. Representative Ron Paul, former Massachusetts Governor Mitt Romney and former Senator Rick Santorum.

The battle for most of those 110 delegates happened in Mississippi and Alabama. Those were the states that held primary elections yesterday. And they were close ones, too close to call when we produced this program last night.

The caucuses were in Hawaii and American Samoa. Those results were still coming in last night as well. You can get all the latest details, of course, from Tuesday's contest right on our home page. You go to the "Spotlight" section, click on the link to the CNN Election Center.

Today's Shoutout goes out to Mr. Moss' sociology class at Farson-Eden High School in Farson, Wyoming.

On the periodic table, cerium, promethium and europium are all what? Here we go. Are they noble gases, halogens, alkali metals or rare earth elements ? You've got three seconds, go.

These are all part of the rare earth elements group, many of which are used in elections. That's your answer, and that's your Shoutout.

You might find some rare earth elements in your phones, and of course we're also talking about things like flat screen TVs, any sort of electronics, really. Luckily, rare earth

elements, despite being called rare, actually aren't rare. In fact, we know most of them come from China.

That country produces about 97 percent of the world's rare earth elements. But other nations accuse China of hoarding these minerals. The U.S., Japan and the European Union are challenging China's restrictions on how much of the materials get sent out of the country.

China says its policy meets international standards.

The countries involved think this is important because of what these rare earth elements can be used for. Chad Myers explains what they can do.

They will power your battery. They actually -- they're the part that makes the power.

They will turn red, green and blue, which are the colors of your TV set. They will make a tiny magnet, which in, with real magnets, would be this size, they could be almost down

to the size of a quarter for the same amount of power, therefore making very small motors or aerospace or for spacecraft or for satellites that go up.

They are elements, they are plentiful in the world. They are all over the place. But a long time ago, China really reduced the cost of them and a lot of mines just basically

went out of business. They couldn't compete. Now China makes 97 percent of these minerals. They don't want to give them away any more.

They want to make things with them, and sell the things rather than just give away the elements, color TVs, smartphones, wind turbines, all of these things rely on these rare

earth elements. They are very powerful things. And they're in the periodic table. There are 15 here.

The lanthanides here, down on the bottom, and then the 21 and 39 here in the middle are they are the biggest ones that we need. And you need them to make -- and to make anything, really, that's now high-tech.

And here's the deal. China says we're just not going to give them away and let you make the things. We're going to make the things and then sell them for higher value than just giving away the elements. That's the issue here.

嗨,我是卡尔•阿祖兹,这里是CNN学生新闻。腾出一点时间来祝大家在这个3月14日派日快乐—好的。让我们先看今天的头条新闻。
两场初选,两场党内预选,110名代表: 昨天在共和党总统提名竞选 中这些已经到了危急关头。
你知道现在的候选人,前白宫发言人纽特•金里奇,美国代表罗恩•保罗,前麻萨诸塞州州长米特•罗姆尼和前参议员里克•桑托姆。
这场几乎囊括110名代表的战争发生在密西西比州和阿拉巴马州。这些州昨天举行初选。他们过于亲密,过于亲密的以致于我们昨晚不能制作这档节目。”
党内预选在夏威夷和美属萨摩亚群岛开始。这一结果仍然在昨晚没有公布。你可以浏览我们的主页,从星期二的竞选中知晓所有的最新细节,当然,你要浏览“焦点”部分,点击链接,链接到CNN选举中心。
今天的大喊答题节目环节由怀俄明法尔森艾登高中莫斯先生的社会学班级提供。
在元素周期表中, 钷和铕的相同属性是什么?现在我们可以开始了。他们同是高贵的气体、卤素、碱金属还是稀土元素?你有三秒钟时间,3,2,1,现在公布答案。
它们同属于稀土元素组别,其中许多都是用于高科技产品。那是你的答案吗?这就是本期的大喊答题节目环节。
你可能在你的手机中会发现一些稀土元素,当然我们也谈论像平板电视,任何形式的电子这样的东西,真的。幸运的是,稀土元素,尽管被称为罕见,但其实并不罕见。事实上,我们知道,它们中的大多数来自中国。
这个国家生产大约世界上97%的稀土元素。但其他国家指责中国囤积这些矿物质。美国、日本和欧盟挑战着中国对于多少物质应该离开该国的限制。
中国称自己的政策符合国际标准。
这个国家认为这非常重要,因为这些稀土元素可用于一些事物。乍得•梅尔斯解释道这种物质的作用。
它们会发动你的电池。实际上,它们是用作动力的部分。
它们会变成红色、绿色和蓝色,这是你电视机的颜色。它们有一点磁性,有真实的磁性,是这种尺寸,对于同等量的力只需消耗它们几乎1/4大小,因此对于小型电动机或航空飞船或卫星不可获缺。
它们都是化学元素,它们在世界上非常丰富。到处都是。但很久以前,中国确实降低了成本,许多矿山基本上关闭。他们不能参与竞争。而现在中国拥有97%的这些矿物质。他们不想给让这种物质溜走。
他们想自己制造产品,并出售产品,而不是仅仅是出售元素,彩电,智能手机,风力涡轮机,所有这些东西依靠稀土元素。它们是很强大的东西。这种物质位于元素周期表中。这里有15个。这里的底部,这就是我们所需要的。你还需要它们做——要做些什么,真的,现在的高科技玩意。
这是交易。中国称不会出售这些元素,让人用这种元素制造东西。他们要制造东西然后以更高的价格出售而不仅仅是赠送元素。这就是问题所在。
