个人感觉这篇文章的条理较之前的更清晰。
1.文章内容： 围绕一个新发现的化石展开：介绍、如何发现并得出可能有生命存在的结论。引出深海热泉可能是生命的发源地。
2. 用了许多 what they think, plausible, seem等不确定的词，严谨。
3. 由发现的新细菌与深海热泉的细菌相似，再至得出深海热泉可能是生物的发源地，环环 相扣。但由于个人理解有限，在读了几遍之后才找到这个研究和深海热泉、生物起源的关系。。。
4. 关于思维导图：一直是将每一段的大意先弄明白，再将几段串起来，跳不出原文的框架，在看到笃师的示范才发现自己的误区——要先能概括这篇文章讲了什么，再归类、细化。
5.关于句式：这篇文章的长句特别多（尤其定语从句），波折号的使用多，术语解释多，穿插在句子中，划分句子成分、指代的理解需要费一番功夫。但对理解长句特别有帮助。
