版本一：
挺难的 很长 4段 pollen花粉在一个什么化石上面 显示出orchids的历史 第一段说原来的人认为这个兰花的历史是某某年以前 然后第二段某个研究表现出 兰花的历史比想象的长很多。。。。
题目1 文章说了什么 选discuss a evidence 什么什么的
好像题目二是说第二段的研究说明了什么 应该是说兰花的历史比written的长 written的内容是指第一段对兰花的研究
版本二：
另一个，说兰花orchid，说有一个蜜蜂的化石发现了，化石里有花粉，有人推论很早就有兰花了，和恐龙同一时期，但是其他人提出另外的意见，blabla...。最后一段最后一句是说此化石形成条件、花儿开花条件和当地气候成矛盾关系。
版本三：
第二篇，兰花，蜜蜂化石和恐龙那篇，篇幅短，但不简单。有一道定位到最后一段的indicate的题
四：（更新于15日）
1. Orchid 历史长短的研究（之前jj已有，具体意思没怎么读，大概讲讲我确定的）。
内容 ：第1段是大概说发现了关于Orchid 历史长短研究的新的证据，和dinosaur有关，揭示了orchid历史比之前想象的要长。这段最后一句是与主题题有关的一句话，大概是说这个这个发现对以前关于Orchid 历史长短的debatable有贡献。第二段描述了之前对Orchid历史的debate，“有人说Orchid relative young，while有人claim反驳了，说Orchid widespread presence & diverse species”。后面的段落不太记得了~抱歉~
题目：1. 细节题，题目是问第1段中提到amber&bee&pollen的那句话，作为an example reveal了什么。答案我不确定，就不说了，免得影响大家考场的判断。2.主题题，这个答案应该是包含了开头consider a evidence和debatable的那个选项，重点句在第1段最后一句，那句里直接出现了debatable。3.细节题，问题是 “用什么证据directly反驳了Orchid relative young”，答案应该是在第二段while引导的那句转折里找，是对widespread presence的改写，d答案好像是说“large scale”。 只记得这3题了~（JJ主人710）
五：（更新于22日） Orchids date to time of the dinos
Ancient orchid pollen found attached to a bee trapped in amber suggests the "supermodels of the plant world" were blooming at the time of the dinosaurs. The discovery indicates that orchids arose between 76 and 84 million years ago, making them far older than experts had previously thought. Experts used the fossil pollen grains to estimate the ages of major branches of orchids living today. Details of the research by a team in the US are published in Nature journal.Despite being the most diverse plant group on Earth, orchids are rare finds in the fossil record. The authors of the Nature paper describe a mass of orchid pollen found stuck to the body of an extinct bee that lived 15-20 million years ago. The remains of the bee were trapped and preserved in amber from the Dominican Republic. Common ancestor Dating the fossil allowed lead researcher Santiago Ramirez to calibrate a "molecular clock" which uses mutations, or changes, in the plants' DNA to estimate the time of divergence between living organisms. By building a "family tree" of orchids, the scientists could move back in time to see when the species first appeared, as well as where and how it spread. They found that the most recent common ancestor of all modern-day orchids lived in the twilight of the dinosaurs, during the Late Cretaceous period. "It is the first identifiable fossil orchid ever found," Mr Ramirez said. "And it is the first case in which an insect-orchid interaction has been observed in the fossil record." The new orchid species, identified from the morphology of the pollen, has been dubbed Meliorchis caribea. The age of the first orchids has proven a controversial topic. Previous estimates have ranged from 26 to 110 million years ago. The Orchidaceae family is the largest in the plant kingdom, numbering at least 25,000 species.

第二篇是兰花那道题
就是前两天一个同学贴出来那一篇改写的，再给大家贴出来 （编者：不好意思我没有时间看英文原文是什么，所以格式很乱大家将就一下）
改写后的文章有三段，第一段说新发现的兰花花粉化石也许可以证明兰花的历史比人们想象中长得多，第二段说兰花历史的长短长久以来就是一个争论不休的问题，有些人认为它的历史比较短，是因为什么什么（不难，但是不记得了），认为兰花历史长的人是因为兰花现在分布很广泛，品种非常多样化。第三段说这个兰花的化石也许可以证明…………（不记得了，但是这句话有考题）。然后就是这种兰花花粉化石非常稀有，因为它存在的年代地球的温度和湿度不适合它开花……题目也不难，但是非常绕，有两道题是这样的，一个问说，文章中引用了一些证据，这些证据可以说明兰花的历史非常长，认为这些证据确实可信的人会有如下那个想法；二，有些人认识兰花的历史很短，并且用什么什么说明，但有些人不同意，并用下面的哪一个反驳？狂晕啊，这两道题都在问一件事，就是觉得兰花历史长的人怎么想…… （JJ主人740）
是这个吧..刚找了下
