句子讲解：

1. Geologists are eager to investigate how this giant rifting valley could affect the future of the Rockies.

【结构简析】在这里的"eager"用的很传神，把地质家们急迫想找到答案的那种心情淋漓尽致写出来，文章中没有用hope或者wish等普通的词。再有就是"could"这个词用的就很精准，把文章的体裁把握的很好。平常写作时，可以仔细地酝酿文章，尽量写地道些的文章。

【参考译文】地质学家们迫切的期盼能够找出原因，为什么这个巨型裂谷很可能会影响未来落基山脉的形状。

　　2. "What we’ve found in springs like this by doing the DNA analysis is that the microbes that are coming up these faults are much more like what we find at mid-ocean ridges （海洋中间的山脊）than like the rivers and streams we could expect in the continental setting."

【结构简析】 这个长句子，我们可以看到从句套从句，不过主要还是由句首what引导的主语从句，在加上much more...than 的句型。第一个that是系表结构，第二个是定语从句，修饰"microbes"。之后的what是引导的是宾语从句。

【参考译文】在泉水中找到的微生物通过DNA的分析检测出断层，这与我们所预想的大陆地面上的河流以及湖泊中的微生物不一样，但却更靠近海洋中央山脊上的微生物。
