宝儿，李笑来作文你有原文吗？还是买了书？

这里好像没有下载，我只找到MP3啊。

还有个问题，邱政政的旧托福听力20段，你是在这里下载的吗？那个录音太不清楚了，昨天听了五篇，简直快要听死我了。。。哪里有清晰的吗？

恩，我在这里下的http://bbs.taisha.org/thread-692625-1-1.html，但是这个我还没看，我朗读的那个好象不是，里面还有其它的什么印度人写的作文，邱政政的就是在这里下的啊，以前的听力段子是不太清楚，刚好锻炼心理承受能力了呵呵

东岸再见

mm的效率好高啊

一晚上可以做这么多事情

我一天也做不完：（

qianrene

见笑了-_-东岸MM，偶是辞职复习呢，嘎嘎

东岸再见

我没办法辞职，唉，效率很低。我是4号考，比mm早十几天。现在我把mm作参照物了。。因为发现我们做的题和进度都差不多，但是mm的实力比我强多了....而且比我投入多了，学习！

加油加油，以期加油

qianrene

mm已经很强了，G比我考得高得多，而且mm口语肯定比我好的，你也加油哦！

qianrene

5，July晚

计划：收集口语素材xdf，老托福段子00后，作文，单词，PARTC

计划赶不上变化，今天心情和身体都不太好-_-||效率一般。。

Delta阅读：1.8A(5/10要撞墙了)24MIN；1.8B(1/10)13MIN；Quiz7(18MIN)；Quiz8(27MIN)；1.9A(错1个)19MIN；1.9B(13MIN)；1.9C(错1)13MIN

新东方《听力特训》：漫不经心听了几个，明天从开头开始

      I've mentioned how DNA has solved many mysteries in biology. And today I want to talk about how it might relate to hypothesis about the travels of the green turtle. Every winter some green turtles make a 2000km journey from Brazil to Ascension Island in the middle of Atlantic, where they mate and lay eggs. But the question is why do they travel so far to lay their eggs? One researcher hypothesized that there are two parts to the explanation. One is natal homing, the instinct that drives green turtles to always return to the beach where they were hatched. The second part has to do with continental drift, the theory that the positions of earth continents have changed considerably overtime. Brazil and Ascension Island were once much closer together, and continental drift drove them apart. But the turtles kept on going back to the island where they hatched. However another scientist question this explanation on the ground that it would be very unlikely that conditions would allow generations of turtles over hundreds of millions of years to keep going back to the same nesting ground every single year. So, what is the connection to DNA? Well, there are groups of green turtles that nest in locations other than the Ascension Island. If green turtles always return to the place where they were hatched, then the turtles that have been going to the Ascension Island to nest would have been genetically isolated long enough to have DNA that was very different from the green turtles that nest elsewhere. But when scientists examine DNA from these turtles, their DNA wasn't that different from the DNA of the turtles that go to Ascension Island. Do you have a shock? Well, we still don't know the answer to the question about why a certain group of turtles go to Ascension Island, but this study was a nice example of the usefulness of DNA analysis to biology.有人能看懂为什么在isolation的情况下它们的DNA是一样的吗？我觉得听听力时遇到这种听懂了词语但是不知道逻辑关系的时候最倒霉。

你划线的那地,说如果turtle是各回各家下蛋的话, 那么回到不同地方下单的turtle,它们的gene应该不同(因为它们isolation,不会有gene的连结).可是结果发现它们的gene一样.  有种可能就是(或证明)上文说的大陆漂移学说(那些现在不在一起的地方原本是一个地,后来才分开的).

谢谢宝儿.

我在这里下载的李笑来的185篇作文听力音频,不知道与这个"完美重排版"能不能对上号...
