   Answer: d  我也选d 但是太确定猜的

I stick on C;

"what the drug’s maker charges for another product with the same active ingredient" may denote a price. I do not consider price of price is idiomatic?

这几道题中间一道见过大家讨论 但不知结论

请教大家

To be discussed...

最后一个我也选D，前两个没有异议。

that引导的定语从句修饰主语,因为太长了,所以后置

如果不管样子好不好看写出来就是: is being tested a new type engine that could eventually propel aircraft anywhere in the world within two hours or help...

weiyu 除了a 你后面的选不出来答案的。 我先认准了de 然后一个个排出 没办法了才到了a  。我同意二楼的解释。

还有第二题that 的话请给出理由。 其他怎么错了。 that怎么对了 谢谢

我的选择是 E D D,

中间那个 three times the price that 和 three times the price of what  这2种说法都可以, 但 中间加了每毫克,  用which比较好

所以我选D

其他2个比较清楚

Q6, i think the best answer is E, A，B 中that从句没有明确的修士对象。c,d中helping不能构成并列。E中it 指代a new engine, and it...与a new type of engine 构成并列，help与have构成并列。其实这题我也做错了，当时已一看到have the capability of...,就排除了b,e而选了c,认为eventually able to propel aircraft anywhere in the world within two hours, or helping做同位语。可见所谓的“xxxx"必错也是相对的。一切只能从句意和逻辑关系上着手。

Q8,i think the best answer is d,其实笨提暗含比较。而只有d是价格与价格的比较。the three times price and what the drug's maker charges

Q28，i think the  best answer is d.
