suse

15是result from the chemical reactions to produce....
而between industrial emissions of sulfur dioxide and nitrogen oxides and atmospheric water vapor 第二个and 才是和between连的，

suse

47题 Unlike that of the Native Americans of British Columbia, the Plains, and the Southwest, those of Puget Sound lived in relatively small, autonomous villages.
是the Native Americans 和 the Plains, and the Southwest比，而those是指the Plains, and the Southwest
明白了吗？

suse

89题  and 前后要对称呀，to do 不能和that句子并列。

suse

91题，B对
因为that 指the distribution of mass,而且两个within很好的和对称了,
另外surrounds 是一次性的动作， surrounding强调是一直都这样，更符合逻辑。

lucylu

15.the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides作result from 的宾语。atmospheric water vapor to produce highly corrosive sulfuric and nitric acids与前半句Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxides 并列。VAPOR在句中作不及物动词，to引导的不定式是vapor的结果。

47.意思为：与住在British Columbia, the Plains, and the Southwest的Native Americans 不同，PS的Native Americans住在relatively small, autonomous villages。
该句暗含的意思是前者的美国本土人可能住在相对较大,但非自治的地区。

89.标准的倒装句,考点也在此。report+宾语+to the government,但whether引导的宾语从句太长，所以后置。句中，information与the necessary reserves 并列，省略了the，两者都作动词have的宾语。

91.like作提示词的平行结构，主要是句式的工整。

As for 15, I agree with suse. (Acid rain and snow) <主语> result from the chemical reactions between （industrial emissions）(of sulfur dioxide and nitrogen oxides)<修饰emissions> and (atmospheric water vapor) to produce highly corrosive sulfuric and nitric acids. 89. I partly agree with lucylu. Corporations will soon be required to report (to the government) (whether they have the necessary reserves to pay the pension benefits earned by their employees)<宾语>, (information that must also be published in annual reports to shareholders) .
