q：50，v：31
虽然不算高，但是也真是尽力啦。
反馈各位CDer
数学：一定能要看鸡精！我遇到了13题
有变体：三个连续整数x<y<z. x+y+z可以被10整除吗
条件1 x + z 可以被10整除
条件2：y可以被10整除
b
语文：
阅读：遇到了公园拥挤；月亮形成；竞争广告（后两篇主要是主旨类题目，少扣细节）
（附件有高还原度原文）
还有一个阅读：关于的是美国废除奴隶制，males忽略了废除奴隶制过程中女性的作用。有个人给了两个理由解释。（只记得大意了）
有主旨题：作者没有态度，只是解释（重点是那个人给的两个理由）
SC：遇到的差不多都是可以用句子结构昨晚的题目，只有两题是要用通过句子意思判断。仔细点就ok
看到的两个鸡精（本裤）：
JOURNAL ARTICLE Chemical Ecology in Antarctic Seas: Chemical interactions can lead to unusual arrangements between species James B. McClintock and Bill J. Baker American Scientist Vol. 86, No. 3 (MAY-JUNE 1998), pp. 254-263 Published by: Sigma Xi, The Scientific Research Honor Society Stable URL: http://www.jstor.org/stable/27857025 Page Count: 10
P3： 然后说他们的这个relationship 不是已经广为人知的parasitism（寄生共生）, commensalism（互利共生）,还有个无关共生（英文记不得了）。parasitism是一方是以另一方的伤害一方受益，commensalism是说双方相互获利，那个无关共生说他们的存在对彼此不造成影响（neutral）然后解释了下这三个的关系。
The association between the sea butterfly and the amphipod falls within the definition of symbiosis, where two dissimilar species live together in an intimate association. However, none of the relationships defined within the broad context of symbiosis-parasitism, commensalism or mutualism appear to suitably describe the sea butterfly-amphipod relationship. Parasitism implies that one species associates with another to the detriment of one of them. Often, the parasite feeds off the tissues or body fluids of its host. Mutualism describes a relationship where both species benefit from the association. Commensalism describes organisms that live in benign and neutral association with one another.
淡水鱼
P2. 然而，很多年前，fresh water 环境相比现在 sterile (这里提到了 coastal sea 资源更丰富什 么的)，脊椎动物不可能一开始就生活在淡水里，更像是从海水逐渐跑到淡水里去的。淡水 产卵，长大了游回大海，这样既避免了海水里天敌的侵扰，获得了淡水情况下稳定的生长环 境。解释从 sea 到 fresh water 来 reproduction，然后还有 fresh water 中的鱼晚熟和晚育证 明淡水环境有其优势~~长大后又可以游回大海获得丰富的资源吧，然后说现在某些地区的 某些生物仍然保持了这种习性，所以某生物先在咸淡混合水区域生活，后来才滚到淡水(有题)。
Freshwater rivers are usually less productive than estuaries or coastal seas. During the early Paleozoic, when there were no multicellular freshwater or terrestrial plants or animals, the rivers were probably more sterile than they are today. Consequently, feeding would not favor movement from estuaries into fresh water.
