　　[00:00.00]This is What’s Trending Today...

　　[00:03.09]Three million years may seem like a long time.

　　[00:08.25]But when you consider that planet Earth is more than 4.5 billion years old, it is a pretty short period of time.

　　[00:19.43]And it is over that shorter time period that the whales in our oceans today got to be so large.

　　[00:30.08]The blue whale is the largest animal that has ever lived.

　　[00:34.80]They weigh more than even the biggest dinosaurs.

　　[00:40.35]They can grow to 30 meters long and weigh up to 130,000 kilograms.

　　[00:49.64]Blue whales are part of the baleen whale family.

　　[00:54.17]Baleen is a kind of food-filtering structure in the mouths of the whales.

　　[01:00.51]The whales developed this system about 30 million years ago.

　　[01:07.09]Other whales in the baleen family include fin whales, bowhead whales, and right whales.

　　[01:16.45]Today, these whales can weigh well over 70,000 kilograms.

　　[01:23.74]But for millions of years, they were not nearly that large, scientists say.

　　[01:31.07]“All of a sudden – ‘boom’ – we see them get very big, like blue whales,” scientist Nick Pyenson told the New York Times.

　　[01:42.26]He and other researchers recently published an article on whale size in the British research journal Proceedings of the Royal Society B.

　　[01:55.73]“It’s like going from whales the size of minivans to longer than two school buses,” Pyenson added.

　　[02:04.32]The researchers -- Pyenson, Jeremy Goldbogen and Graham Slater -- believe that a change in the Earth’s climate caused whales to get so large only about 3 million years ago.

　　[02:21.25]This change led to food becoming more easily available.

　　[02:26.46]An oncoming ice age made the ocean water cold.

　　[02:30.96]High winds mixed the water in the ocean faster than before.

　　[02:36.77]Rain and snow made more nutrients run off from the land into the water.

　　[02:44.14]The nutrients resulted in algae.

　　[02:47.68]That attracted small fish and shrimp called krill.

　　[02:53.52]The mixture of nutrients resulted in more food for large whales to eat.

　　[02:59.90]Whales that were able to quickly eat a lot of food survived. And they got larger.

　　[03:07.11]Whales that had teeth instead of baleen, however, did not survive.

　　[03:13.65]The largest baleen whales then produced other large whales.

　　[03:19.78]Over the next three or four million years, the baleen whales grew 10 times bigger than they had been, the researchers say.

　　[03:30.65]It is possible that the largest whales are gone, the researchers said.

　　[03:36.63]But, as they told the BBC, blue whales could grow even bigger -- or they could slowly die – depending on Earth’s changing climate.

　　[03:49.80]And that’s What’s Trending Today.

　　[03:52.30]I’m Dan Friedell.

　　拓展：选择高考英语听力材料的方法

　　1、选择高考英语听力材料方法

　　不要选择专业术语、专有名词较多的材料。专业术语之类难词、生僻词对于绝大部分同学来说不需要掌握，因此练习时可以忽略掉。而如果选择的材料中这类词汇较多的话，无疑给自己设置了很多不必要的“拦路虎”，会影响练习的流畅性，应予以避免。

　　2、选择高考英语听力材料方法

　　注意语段材料的时效性，时效性越强越值得练习。不宜听写已经过时的英语语汇内容。如一些出自名家之手的英语美文，文采固然是好，但可能是百多年前创作的作品，其中一些用词，可能现代英语中已经不用了，或者用词比较艰深晦涩，这种材料就只适合单纯欣赏，和同学平时的英语使用情况相去甚远，对大家所面临的`考试更是没有针对性，不适合用来练习听写。

　　3、选择高考英语听力材料方法

　　基础不佳者不宜用影视剧对白练习听写。这类材料可能含有过多口头语或俗语，且语速非常之快，对于英语程度不扎实，听写能力有待提高的同学来说很难听懂，更别提听写了。对于面向四六级的大部分同学而言，影视剧作品是可以作为听力和口语的练习素材的，但前提是，不要直接听写，应先结合中文字幕把大意听懂，然后作为泛听材料，单纯地通过听练习一下语感，使自己在听觉上习惯地道的英语语音语调，并起到口语纠音的作用，同时听加深记忆，学习一些剧中的口语表达。

　　4、选择高考英语听力材料方法

　　刚开始练习时，材料篇幅不宜过长。篇幅过长容易导致过度疲劳，会使练习者丧失兴趣。可先从简单、短小的材料练起，循序渐进，不断体会自己的进步和成就感，这样比较合适。随着练习的深化，可慢慢地逐步接触长篇材料。

　　5、选择高考英语听力材料方法

　　不推荐听收音机节目来做听写练习。这是因为收音机里的内容不可重复，万一第一遍没有听懂，则无法反复听，做循环练习。而且，收音机里的英语内容没有录音文稿，也就意味着听完没法对答案，这对实际提高能力帮助甚微。建议使用磁带或MP3材料，这样可以根据各人需要反复聆听，且所选材料一定要配备录音文稿。
