B：1.用平行排除，A 's B not B by A
2.Ron: "including" specifically implies that the following enumeration is NOT exhaustive. Including不是穷尽枚举

mark
A/E while从属连词，必须连接两个句子
"while" MUST be used with a clause or __ing phrase

mark as much/many as的使用限制；
B选项the increase已经包含了the number了，无需再次用that指代！

想问下 第9题 DE选项的时态是过去完成时怎么解释呢

1/3....1 2^n是4的倍数

B选项，并没有彻底的反驳journalist的话语是反的；只是突出这个fact不足以证明journalist的观点

One point these journalists overlooked is that in 1997, as in the twenty-four years immediately preceding it, the real GDP per capita grew nearly one-half percent a year more slowly than it had on average between 1873 and 1973.
B选项两个错误点：1.文中原句指出1873-1973年间average的值，不是每年的值；2.原文中提及的原因是1997和（1873 and 1973）的对比，而不是1997年之前和（1873 and 1973）的对比。
看清楚题！！！

A survivor of the changes that swept the travel industry as a result of the deregulation of the airlines in 1978, this agency adopted a unique structure for globalization. Rather than expand by attempting to develop its own offices abroad, which would require the devel- opment of local travel management expertise sufficient to capture foreign markets, the company solved its globalization dilemma effectively by forging alliances with the best foreign partners it could find.

Wadati's work suggested that deep events occur in areas (now called Wadati-Benioff zones) where one crustal plate is forced under another and descends into the mantle.

别想那么多乱七八糟的，抓准题干里的conclusion。相信我兄弟萌

CD的区别在于是这种海洋白帽对全球变暖的影响是海洋环境的一个方面，还是海洋白帽影响了全球变暖这件事是海洋环境的一个方面？
应该是生物对环境的影响是环境的一个方面，而不是生物影响了环境这件事是环境的一个方面-->加强对句子的抽象能力
having done/to have done，先时性；being同时性
D，having been incorporated into the computer models 表示在is现在之前，很多个方面没有被包含进电脑模型
E，not yet being incorporated表示与have现在同时的没有正在被包含进电脑模型
C，are not yet incorporated，一般现在时，没有被包含进电脑模型，ok-->原文意思是现在没有被放进模型里，不应用完成时

【引用】U is the set of integers that are in S only or in T only or in both, and the number of integers in U is 10.。所以U是S, T的并集。

nearest $1,000,000,000 is $43,000,000,000，四舍五入，变动范围是42500m~43400m
nearest 1, 000,000 is 86,000,000，四舍五入，变动范围是85500k~86400k

整理式子，a1...an的乘积=(n+2)/2,题目要求是否为整数，即要求n+2是否为2的倍数，即n是否为偶数；条件1中，当n+1=6时，n=5,则不满足要求，条件2满足，选B

For many years, historians thought that the development of capitalism had not faced serious challenges in the United States. 没有挣扎
Recently, however, some scholars have argued that even though laissez-faire became the prevailing ethos in nineteenth century America, it was not accepted without struggle. 有挣扎
Hard times continued to revive popular demands for regulating business and softening the harsh edges of laissez-faire capitalism.最后总结

Conventional financial analysis pays limited attention to issues of market structure and dynamics, relative costs of information, and problems of income distribution.

Moreover, it is assumed that transaction costs for various types of financial instruments(stocks.bonds,etc) are equally known and equally divided among all community members.

二刷，还是做错。继续误选D。
做题时的思路：按照毕老师这一套理论，这个也能算是因果推理里的干扰因素？因为这个限制，所以医生无法履行其道德错误。然后E选项只是重复了医生的道德义务这一原题中的事实，并没有对逻辑产生影响。
有哪位大佬来反驳一下我的观点没？

文章主要讲的是两派学者的观点，而非问题，所以选B

【引用】bottom line是利润表的最后一行，在经济学中有净利润的意思
原文：Clearly price promotions are generally run at a loss, otherwise there would be more of them.
所以 没有经常举办这个活动的原因是因为run at a loss即亏本，没有利润
问题问价格促销对于利润的影响（即没有利润）的证据是什么，就是因为没有经常举办这个活动呀，没有经常举办这个活动就是它亏本的证据；
综上，AC选项与利润无关，DE选项应该是对于利润有正面影响的，因此对利润会存在负面影响的选项为B

首先很容易看到单独的每个条件都不能确定能不能watered completely the lawn~
然后关键是考虑两个条件结合以后

冷知识：圆内内接矩形面积最大的是正方形，

所以从极限的角度去思考，假设从条件2给的内容来看，把每个sprinklers都开到最大，即半径2 yards，这个时候若因为the lawn是矩形（条件1），则想要完全无死角地覆盖的话就考虑每个圆形最大可以提供多大的矩形，可以发现每个圆形中最大的矩形就是边长为2倍根号2的正方形，面积为8，刚好四个这样的圆形，最大可以组合成面积为32的矩形

但是！根本没告诉你这个面积为32的矩形lawn具体长和宽是怎样的。。。 所以以上的一番分析 都是多余的hhh
