of the 230 vs of all/the total of

including 的选项中后面都跟了to

the time required for a stroke is exactly equal to the time interval between strokes 要注意审题

审题错误，以为是从以下选项中选一个较大的数

不要再把proponent 和opponent 搞反了:)

选的是最大质因子

这道题明确提到了This geometric solid consists of 2 pyramids, each with a square base that they share. 所以不用深究到底怎么折，直接按照重叠的金字塔来结题

DE选项的纠结可以用取非则weaken 来解决。但是要注意取非是logical negation.而不是polar opposite
用取非则weaken的办法来做会发现：
D选项非后就是，If there are language centers on the left side of the brain, any serious stroke affecting that side of the brain damages none of them.
Stroke不影响语言中心，那么就压根不能推出结论
E取非：
It is possible to determine which side of the brain contains a person's languagecenters if the person has not suffered damage to either side of the brain.可能决定。这种模棱两可的答案怎么可能成为assumption。

就算用because of ，也应该是enhancement。动名词错误。语义也错误

问的是second argument。。不是second paragraph。。还自以为聪明的把和第二个观点相关的迅速排出了。。？？！

粗心把sum算成了48*9+26,扶额

careless 粗心，A偷换概念

This question is trying to state a "general" situation - "Sales of telephones have increased dramatically over the last year".
So one way to attack the final statement in the passage is to state that the generalization does not apply to a specific situation - MI's situation.
increase是普遍的，不适用于M个例。所以削弱就是说M是decrease

造成的影响就是被边缘化，从而才有后来的暗流等等。。。

这里的significant effect 说的不是好的影响？而是不好的影响？

做笔记，记住是去年的事故率是 P>O

一开始算出了一个错误答案是8，因为我把2（3/5)理解成了2*(3/5)

B：a state of affairs把the second boldface定义为fact，然而分明是claim，即consideration
the use of genetically engineered seeds of this kind is likely to become widespread——这个明显不是fact

不定式表示的是一种“主观性”，即，表达一种状态的转换（start-stop）。
从句表示的是一种“客观性”，即，表达一种状态的稳定（process）。

因此，对于不定式和从句的区别，我们可以近乎照搬所有不定式和ing的区别的判断标准。

as high as 应该接一个具体值，而不是一个范围
some of our players weigh as much as 300-325 pounds --> bad phrasing
some of our players weigh as much as 325 pounds --> good phrasing
a height of——idiom
