前提：X国和Y国是一样的气候，但是X国和Y国农业产量不同（X国下降，Y国上升）
结论：判断X国农业产量下降的原因不是气候，而是高度集中的中央经济

果因题求削弱：
中央经济影响农业 → 相同气候X和Y农业产量不同
D选项表明，相同气候农业产量之所以不同，是因为X国和Y国作物不同导致，他因削弱。
错选B，因为D更加直接！

Unfortunately, because this approach fails to deal with the underlying causes of inflation, wage and price controls eventually collapse, the hitherto-repressed inflation resurfaces, and in the meantime, though the policymakers succeed in avoiding a recession, a frozen structure of relative prices imposes distortions that do damage to the economy's prospects for long-term growth. 没有提到会succeed in decreasing inflation

there is nothing "ironic" about choice C.
choice C says, basically, "Historians had a certain emphasis, and that emphasis excluded certain people." ...nothing ironic about that.

choice D is supported by the passage:
the development of archival research and the critical editing of collections of documents began to reveal significant new historical evidence concerning women, yet this evidence was perceived as substantially irrelevant
also, you can see how this is ironic: a whole bunch of new stuff was found... but it was ignored.

#摘：
yet this evidence was perceived as substantially irrelevant: historians saw political history as the general framework for historical writing.
irrelevant这里的意思是“不重要的” 也就是说这些证据被认为不重要的（和D中ignored）表达的意思一样
（如何判断irrelevant该翻译成“不相关的”还是“不重要的”？）
看冒号的解释historians saw political history as the general framework for historical writing.
历史家把political history看成一般的framework 也就是说他们没有重视这个political history
！！！relevance也有一个意思叫“意义” （Gmat还有一题考到这个意思） 切记啊

① prohibit的idiom: prohibit sth; prohibit sb from doing; prohibit from doing
② 描述agreement的内容，用现在分词作定语修饰更合适

① less/fewer:
② a number 不能指代 7 people
③ the ones指代已出现的
④ 平行结构: Ron: in the choice with "those killed by bee stings" -- note that we don't have "people killed by the great white shark" in the other part.#

通货膨胀率和生产者物件指数的关系

A were more likely to do sth than B were，主句是SVO结构，此时被比较部分一定要带上谓语动词be，
A were more likely to do sth than B，会让人误解为A were more likely to do sth than do B
【总结】A is more likely to do than B is
选项A， 代词those的指代对象是句前出现的patterns of stress，that引导的定语从句是修饰代词those的。补出的be动词are表明了比较的是两种情况，而不是“男孩的经验”。

A选项：Correct. 许多Jackson的支持者反对由于加入国民经济而引发的商业化。这个选项属于直接反对。不论是什么为基础的商业化，只要被“Jackson”的支持者反对了，都是反对作者对于Jackson任期中“商业化”这一论点的。

定位最后一句话，“For example, the classical conception of leadership was incompatible with our modern notion of the freedoms of speech and press, freedoms intimately associated with the legitimacy of opposing political parties.”。D选项：Correct。这样的价值观不是18世纪英格兰传统古典人文主义学者所有的内在价值观。从考点中说的定位句可以知道，既然两者本来矛盾，那肯定在18世纪的英格兰“言论自由”这个价值观是不存在的。

错选D，定位句第二段Commerce—its profit-making, its self-interestedness, its individualism—became the enemy of these classical ideals. 说明前六位总统不强调individualism。正确E，定位在“he does rightly see Jackson's tenure (the seventh presidency) as the culmination of the acceptance of party, commerce, and individualism. ”是作者对“Ketcham”观点的评价也是认同。同时说明了在“Andrew Jackson”时期，政党被广泛接受。

注意，题目问的是两个老管理系统之间的相同之处！，错选E，长期目标是新管理系统TQM，短期目标才是老管理系统。正确A ，定位句，TQM shares with such systems the ultimate objective of increasing profitability，说明老系统对增加利润感兴趣

错选E，作者没说优点，知识陈述该管理系统与其他系统的关系。

【注意题意】科学家抱着做研究的目的进入科学领域，并且只会接受那些有相同志向的人做同事，因此当一个科学家拿奖了，【Conclusion】其他人都认为这个人就不应该被当成是同事了
d, 补出了中间的gap: 拿奖的科学家没有动力再去做新研究了
错选c, 一个科学家可以在不完成重要的研究的情况下依然成为一个流行人物。这个和结论没关系！

① 比较的平行：A中的people和US进行比较不对。
② 代词：their的指代不清
③ 所有格：C中的the US's无法还原
④ 句意：D中的rate of foods，E中的rate of people句意都不对，应该是rate at which ....

分词可作为平行元素，所以found和resembling都是bird的modifier

（1）可以判断，（2）说明a-b>1,或者a-b<-1;第一种情况可以判断原式必定不成立，第二种情况可以判断原式必成立，但（2)有这两种情况，所以还是不能判断，选A

已购买社群课，请问如何入群？

①代词：A/B的it指代profits，应该是复数。#遇到代词的时候看看其他选项有没有其他形式，或者没有这个代词#
② 时态：first 3 months与last 2 years有时间先后关系，需要有体现，AB的时态没有体现
③ with结构：D/E中with结构修饰profits还是修饰主句可能有歧义.
④ after having done: 这个结构是reluctant的，因为after已经表达了时间上的前后。

那～B中是否包含P（A）的情况呢？
