1. In a review of 2,000 studies of human behavior that date back to the 1940s, two Swiss psychologists, declaring that since most of the studies had failed to control for such variables as social class and family size, none could be taken seriously.

(A) psychologists, declaring that since most of the studies had failed to control for such variables as social class and family size,

(B) psychologists, declaring that most of the studies failed in not controlling for such variables like social class and family size, and

(C) psychologists declared that since most of the studies, having failed to control for such variables as social class and family size,

(D) psychologists declared that since most of the studies fail in controlling for such variables like social class and family size,

(E) psychologists declared that since most of the studies had failed to control for variables such as social class and family size,

Verb form; Diction

The subject of the sentence, two Swiss psychologists, needs a main verb. The -ing verb form declaring cannot, on its own, be the main verb of a correct English sentence. Furthermore, the clause that addresses the reason for not taking the studies also seriously needs a subject (most of the studies) and a verb (had failed).

其实细看OG的解释下来怎么感觉就是在说语法错误呢？为什么说OG的解释隐晦是因为需要我们去揣摩

例如这里addresses the reason就是在告诉你后半句和前半句的联系是因果关系，因为写OG解释的和出题的人不是一群人，他们的思路有差距是肯定的，但是在我看来，差距不太明显，因为这是native people写的解释，我们越靠近就越能轻松的解题；他们不可能兼顾到所有的错误，他们只能在有限的空间内抓住他们对主要错误的解答，而我们，就是需要在主要错误的解答上思路尽可能保持和他们一致，抓出他们的潜台词，当然，这个能力肯定是多次刷下OG的感觉，通过题与题的联系，别想着一次升仙，我不否认这种人的存在，但是绝对是非常少数的人们，踏踏实实的好好分析140题，反复反复就会有那么一瞬间你会发现你真的开窍了

再来对于正确选项的分析和理解：

这题的正确选项是E：

In a review of 2,000 studies of human behavior that date back to the 1940s, two Swiss  psychologists declared that since most of the studies had failed to control for variables such as social class and family size, none could be taken seriously.

我想对正确句子的学习就是要去持续的提问去challenge，去把它当成和一个人之间的对话，当然我知道这很难，不过真的会分析出乐趣来的= =

Q： 当我读到in a review，我就会想什么review？很难理解啊好像

A:读下去，of 2000 studies of human behavior that date back to 1940S。恍然大悟，原来是这么一个货，挺清晰的啊不错

Q：declared that这个为什么用的that？

A：想起了manhattan的知识点就是表示一个句子尽量用的that对吗！如果核心结构是句子就用的that；核心结构是名词的话就是declare + n；所以这里我们就用that，因为核心是个句子

Q：since怎么这么眼熟？

A：since出现要用完成时，然后和because split开的话可能是很差的选项，想起了OG12的第一题

类似的Q&A可以出现很多次，最重要的是自己要知道自己的答案是正确，不断去提问不断去解答来加深自己对题目出题意向的理解，了解为什么正确选项表达就是如此的清晰有效！

再来是关于prep和OG的串联

OG12-26：

  Emily Dickinson's letters toSusan Huntington Dickinson, which were written over a period beginning a fewyears before Susan's marriage to Emily's brother and ending shortly beforeEmily's death in 1886,outnumber her letters to anyone else.
