RON: "what the drug's maker charges" is ... guess what ... a price.
therefore, "three times the price of what the drug's maker charges" would refer to the price of a price. that is illogical.
this construction is thus not only "wordy", but actually nonsensical.

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.

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

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
