句子講解：

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

【結(jié)構(gòu)簡析】在這里的"eager"用的很傳神，把地質(zhì)家們急迫想找到答案的那種心情淋漓盡致寫出來，文章中沒有用hope或者wish等普通的詞。再有就是"could"這個(gè)詞用的就很精準(zhǔn)，把文章的體裁把握的很好。平常寫作時(shí)，可以仔細(xì)地醞釀文章，盡量寫地道些的文章。

【參考譯文】地質(zhì)學(xué)家們迫切的期盼能夠找出原因，為什么這個(gè)巨型裂谷很可能會(huì)影響未來落基山脈的形狀。

　　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 （海洋中間的山脊）than like the rivers and streams we could expect in the continental setting."

【結(jié)構(gòu)簡析】 這個(gè)長句子，我們可以看到從句套從句，不過主要還是由句首what引導(dǎo)的主語從句，在加上much more...than 的句型。第一個(gè)that是系表結(jié)構(gòu)，第二個(gè)是定語從句，修飾"microbes"。之后的what是引導(dǎo)的是賓語從句。

【參考譯文】在泉水中找到的微生物通過DNA的分析檢測出斷層，這與我們所預(yù)想的大陸地面上的河流以及湖泊中的微生物不一樣，但卻更靠近海洋中央山脊上的微生物。
