2月19日 北美 机经

第一次考，虽然在考前觉得自己还需要一点儿时间复习，但是只能硬着头皮上了，我的语法练了很久，结果一上考场第一题还是不会，阅读因为平时没练习，靠机经，逻辑属于语文部分的强项了，但是估计掉进低分库了，后面语法超级简单，逻辑花的时间也比平时少得多。V29（53%）  数学49（很丢人的分数）  总分640，不知道要不要继续奋斗一次。楼主英语基础，本科在国内读的，托福美国考了2次，每次80+。

作文（不知道是不是机经里的） 一封给小区的信里说：某杂志(fitness magazine)卖得特别快是因为里面刊登某个运动的machines，所以为了maximize 小区居民的锻炼，小区新建的活动室（暂且如此称呼吧）应该购买这种机器。 很短的不到三行的话。

IR  第一次考，也没有练习过，完全乱做的，不过后面的题目很简单，基本都是下拉的。

数学 做得很痛苦，练习太少了，pace很慌张。很多题目不记得了。

语文：
逻辑：语文部分里考得最开心的就是逻辑了，基本一眼都能扫出来。机经部分有第5题，14题，44题，81题
还有一个是一段很长的话，说希腊在某个地方挖出一个tool，大家认为哪个工具是非洲那里制造的，因为跟非洲的工具很像并且非洲的工具在古时候会传播到亚洲和欧洲，但是希腊挖出的这个工具虽然很像非洲工具的特征，可是时间更早，问能推出什么，（不是机经73题）
我选的是说明这个工具不是非洲制造的

说一个节目的空档时间一般只放7到8首歌，但是现在要增加到10首歌，有人就说这意味着广告会变少，问assuption
我选的是这10首歌曲，每首歌曲的长度不会比以前的短

阅读：男半球女半球，妇女的历史研究， 23博物馆，  加拿大好基友，其中前2篇很绕，妇女的历史研究出现在我的前10题中，完全看不进去，所以悲惨的掉进低分库了。
博物馆那篇很全，可以参考答案，基本可以秒选。
加拿大好基友有问这4段什么关系
还有Cambrian 时期怎么样的：（一共4段，大约就是以下这样的结构）
For decades, the Canadian geologist Martin Gibling has been intrigued by the tough-to-prove hypothesis that land plants created the shape of modern rivers hundreds of millions of years ago.Plant roots reinforced the ground, the thinking goes, creating stable banks that funneled what once were wide, shallow water flows into narrower and deeper channels. By extension, that set the stage for lots of significant Earth history events, including the rise of human civilizations in modern river basins so many millennia later.

Now Gibling and postdoctoral scientist Neil Davies, both at Dalhousie University, have strengthened this case. When the pair compared a much-improved plant fossil record with evidence of how rivers changed very long ago, the transitions matched up.“As soon as the plants got a foothold on land and rooted vegetation started, that changed the landscape. Basically plants engineered that landscape as they evolved,” says Davies. He and Gibling have published the findings in both Geology and Earth-Science Reviews.Back in the Cambrian period, which ended some 500 million years ago, the geologic record indicates that rivers were very shallow but wide things, almost floods that allowed rainwater to wash from largely barren solid ground to sea.

But by the time of the Silurian- Devonian boundary, some 420 million years ago, the picture found in preserved sedimentary rock changes. The blankets of unconsolidated sediment found in earlier river deposits appear less frequently. It happens just as evidence of land vegetation with root systems also expands in the rock record.
In addition, more complex and diverse river remains emerge, including more traces of mud, probably due to the enhanced chemical weathering that plants assist; smaller-sized sand grains; and samples of organic remains. Significantly, shapes shift too.Organized deposits become visible in the remains of highly sinuous, single-thread channels. Evidence of lateral accretion—the digging away of material at the outer bends of a river and the simultaneous deposition of material at the inner bends—is more abundant.

They want to explore whether any of the periodic mass extinctions experienced on Earth might have affected the shapes of rivers as well. They are scouring the literature for changes preserved from the end of the Permian, when a lot of plant life was wiped out.

语法：平行考得很少，倒是 morn.. than　　考了不少
第一题．．ｗｏｕｌｄ　ｇｕｅｓｓ．．．　　我不知道这后面该用原型还是不该用
比较级考了好几道，不难。
有一道题挺变态的开头是quote一个人的一句话 "......." 某某人said in a telephone interview　　　这个也考到了
对比的应该是A city的人挣的钱比B city的人挣的钱多，所以就是钱比钱。这个也考到了，最后半句...earned more than          选项有 the amount in that country, that country 就记得这连个选项

还考了一个类似“你们的提议是well sounded, but you intentionally unstated how permanent it is and impact of it”类似的吧，选项是各种permanent和impact的用法，我选了最短的那个its permanency and its impact，因为看了机经，都选成名词，不知道对不对。
