V1:
p1: 有一种叫resin的物质，和sap和gum很难区分，并且其物理特性未被鉴定。resin和sap，gum比较的时候，还列举不少sap和gum的特性，[有考点，问哪个特性sap有EXCEPT]。
p2: 说了resin的一种特性，描述说resin本来能抑制虫子，但后来虫子免疫了这种东西，开始吃resin(还是有resin的植物？)[有考点，问下面哪种说法，符合resin和organism的关系]。总结说，这种resin和其他organism之间的化学反应，给ecology领域，带来了啥啥啥的影响。
考题:
1. 有考点，问哪个特性sap有EXCEPT
2. 有考点，问下面哪种说法，符合resin和organism的关系

讲得一个什么病貌似是色盲还是什么的，单词不认识，人们研究出一种方法叫什么pop out来辨别这种病，做试验里面有什么4S,5S的，我也不懂什么意思。第二段讲这种方法还用来辨别这种病是不是perceptual, 做试验里面有什么在黑色的背景里面辨别三角形的，问题有主题题，还有对第二段的重点定位，要仔细读

Color blindness, a color vision deficiency, is the inability to perceive differences between some of the colors that others can distinguish. It is most often of genetic nature, but may also occur because of eye, nerve, or brain damage, or due to exposure to certain chemicals. The English chemist John Dalton published the first scientific paper on the subject in 1798, "Extraordinary facts relating to the vision of colours",[1] after the realization of his own color blindness; because of Dalton's work, the condition is sometimes called Daltonism, although this term is now used for a type of color blindness called deuteranopia.
Color blindness is usually classed as disability; in certain situations, however, color blind people have an advantage over people with normal color vision. There are some studies which conclude that color blind individuals are better at penetrating certain camouflages.[2]
新（第一段：讲the study of the origin of 什么东西 is difficult, 然后又讲molecular science 怎么研究这个问题，其中好像有两个专家的debate。
第二段：说molecular science 对origin的研究也没什么用，因为不知道什么sequence之类. 这篇文章很长 |
