小编:洛伊 1814 综合点评
作为暑假末的第二场考试,今天的考试依然是采取几套题拼盘的形式,普遍考生觉得较难,特别是
加试题目,总体上考试的话题依然是会重复一些这两年考过的文章,以及再现一些TPO文章主题,
建议考生们利用好机经和TPO真题来好好复习。

生物类WeakElectricSystemsinFish
内容回忆
文章开头讲了一种鱼(elephantnosefish)能够通过放电来探测周围水域的物体,这种
现象被叫做放电定位(electrolocation)。这种鱼终身都会放电,不过电场很弱,很难被人操
作,但是却能形成电场,任何对象进入这个电场都会被扭曲。弱电气系统有一些规则,比如
探索新环境即使他们看不到。科学家不仅对electrolocation感兴趣,也对他们对这类鱼
的沟通感兴趣,他们发现这些鱼沟通主要的功能有:求偶交配、侵略行为(aggression)

TheFormationofEarth’sAtmosphere
内容回忆
重复2016年11月26日以及2017年3月11日:文章开头提到了地球早期的大气里是
只有氢气和氦气,因为地球原始大气非常炎热,构成原始地球大气层的气体分子的一
个特点是会不断地高速移动,有一个极端的假设是如果这些分子不是互相抵消中和的
话,地球的大气层到最后就会消失;另一个关于这些气体分子的特点是当这些气体分子
移动速度快到一定程度时,这些气体是可以不受地心引力的控制的,氢气和氧气是损
失的最多的两类气体分子;地球上的火山爆发带来了水蒸气和二氧化碳,水蒸气凝结
为现在的海洋;在原始的大气中是没有氧气的,但是有一类细菌是厌氧性细菌并且可
以将空气中的二氧化碳转化为氧气,并且这类细菌最后会沉淀构成了现在的海床;最后
一段是讲为什么氮气是现在大气中构成最多的气体,氮气的形成十分缓慢,但是相比
二氧化碳和水蒸气,氮气非常难以消散和离开地球,因此随着时间的推移氮气渐渐成
了空气中最主要的构成成分。

第一段:冰川对陆地的作用很大,冰川的重量会使大陆表面下降,这个过程时间很长,然
后地球表面又要用很长的时间来恢复原来的高度。
第二段讲冰川的移动,随着冰川越来越大,收到重力的影响,会慢慢地移动,移动过程中
会切割岩石,推倒树木,摧毁一切的植被生物。
第三段:在平坦的地方形成的冰山会缓慢移动,朝各个方向发展,在山谷形成的冰川,因
为垂直角度大,会形成V型冰川。
最后一段:冰川会形成很多地形。

教授喊她来,有个杂志征稿,是个好机会让她投稿,然后她说之前的杂志获奖编辑没选上的可以吗,
教授说相信你的艺术感觉,光线和构图非常棒。

望远镜的进步。然后说变形是shapes,可以体现年纪。最后说科学就是这样在推翻和反复中发展什

的影响,而有些人认为是已经做过类似的题的原因。

考题回忆总论点一种flatworm引进欧洲后对当地的物种产生了很大的危害,生物入侵。文章中有三种
解决方法来减少这种虫的数量。
阅读部分1.Biologymethod:从这种虫子的发源地import一种它的predator来吃掉或者让欧洲
本地的鸟类和爬虫类来吃它;
2.Chemistrymethod:用化学杀虫剂来杀掉这些多余的虫子,寻找一种对它有害但是
对别的物种无害的化学杀虫剂;
3.Dipthesoilofthetransplantedplantsinhotwater.热水可以杀死土里的flatworm的
卵。
听力部分1.在原产地没有发现这种虫子的天敌,并没有动物吃这种虫。而且在欧洲的鸟类和
爬虫类也不吃这种虫子因为它的味道酸而且令人不悦;
2.这种虫子对于大部分化学杀虫剂都resistant。只有一种杀虫剂对它能产生危害,但
这种杀虫剂对于其他的wildlife也会产生危害;
3.如果植物的土很大,即使放在热水里也不能穿透土壤。所以土壤深处的虫卵还是
能够在热水泡过之后存活下来。
解题思路解释听力如何反驳阅读内容。

考题回忆在工作中得到更高的职位或者在学习中获得更好的成绩,你会选择以下哪种方法:
1.多做extraoradditionaljobs;
2.participatemoreactivelyorstatemorepersonalopinionsingroupdiscussions.
解题思路这篇文章可以按照平行架构构建文章,一段讨论工作,一段讨论学习,再设置一个让步段。
1.在学习中为了获得更好的成绩,需要更多的参与到小组讨论中因为一般最终成绩的评判都会分为
考试以及平时的表现;
2.在工作中,为了得到职业晋升,在小组的表现尤为重要因为可以更好的向同事和supervisor展示
自己的综合能力:自信,沟通能力,口才和逻辑等。
