6/2倒计时40天，一切都不重要，小Nerv只想忘我地专注于一件事

Nerviously

一战去年年底，爆低的分数我看到自己都笑了，在这里就不详细说明了。当时考场上题都读不进，读了两句就开始回忆寂静，现在想想分数也不冤枉。
回想自己过去的20年都是浑浑噩噩的过去，总是下了决心有没有付诸行动，所作的一切都只是还好而已，总是害怕面对。注意力总是集中不起来。
就这一次，我希望自己把分数什么的抛开，把急功近利的心态抛开，把浮躁抛开。因为小Nerv我现在唯一想做的就是忘我地专注于一件事，
报一下小Nerv现在的复习进度：og过了2遍，perp笔记07，08各一遍，gwd模考做了TN版本的1-6，最多错了17个T T, 最少错5个（建立在sc&cr很多都作过的情况下），gmat单词过了一遍。
本人的英语基础较弱：四级：506;  六级512；不知道现在接下来该重点看什么，正打算再把og看一边，望各位指点

泾渭不凡

加油的~~正确率很乐观的~~加油哈~~

Nerviously

今天一下午又把单词过了一遍，现在重新开始看og，看到一个问题贴出来
In late 1997, the chambers inside the pyramid of the
Pharaoh Menkaure at Giza were closed to visitors for
cleaning and repair due to moisture exhaled by
tourists, which raised its humidity to such levels so
that salt from the stone was crystallizing and fungus
was growing on the walls.
(A) due to moisture exhaled by tourists, which
raised its humidity to such levels so that salt
from the stone was crystallizing
(B) due to moisture that tourists had exhaled,
thereby raising its humidity to such levels that
salt from the stone would crystallize
(C) because tourists were exhaling moisture, which
had raised the humidity within them to levels
such that salt from the stone would crystallize
(D) because of moisture that was exhaled by
tourists raising the humidity within them to levels
so high as to make the salt from the stone
crystallize
(E) because moisture exhaled by tourists had raised
the humidity within them to such levels that salt
from the stone was crystallizing

C Th e pronoun them seems to refer to tourists,
which is nonsensical; the entire construction
is awkward and wordy; would crystallize is
not parallel to was growing.
D Once again, them seems to refer to tourists;
the entire construction is awkward, wordy,
and ambiguous; crystallize is not parallel to
was growing.
E Correct. Th e causal sequence is clear, and
them clearly refers to chambers.

c，d都说them指代tourists，为什么e就指代chambers了。og解释的意思看不太懂，望高人指点阿？

还有哪里有manhattan sc的实体书啊，电子版看地眼瞎阿
