. Alaska regularly deposits some of its profits from the sale of oil into a special fund, with the intention to sustain the states economy after the exhaustion of its oil reserves.

   (A) fund, with the intention to sustain the states economy after the exhaustion of its oil reserves

   (B) fund, the intention of which is to sustain the states economy after they have exhausted their oil reserves

   (C) fund intended to sustain the states economy after oil reserves are exhausted

   (D) fund intended to sustain the states economy after exhausting its oil reserves

   (E) fund that they intend to sustain the states economy after oil reserves are exhausted

The normative model of strategic decision-making suggests that executives examine a firm’s external environment and internal conditions, and in using the set of objective criteria they derive from these analyses, can decide on a strategy.

A. conditions, and in using the set of objective criteria they derive from these analyses, can decide
B. conditions, and they use the set of objective criteria derived from these analyses in deciding
C. conditions and, in using the set of objective criteria derived from these analyses, deciding
D. conditions and, using the set of objective criteria derived from these analyses, decide
E. conditions and, in their use of the set of objective criteria they derive from these analyses, they decide

答案是D，但是我认为D不对！因为这个题目是examine和decide平行，中间还套着environment和condition平行，大平行套小平行为了区分不是应该在and前加“，”么？？？所有选项里就D没有逗号，为什么偏偏D对呢？？

Besides yielding such psychological rewards as relief from stress, deep relaxation, if practiced regularly, can strengthen the immune system and produce a host of other physiological benefits.
(A) deep relaxation, if practiced regularly, can strengthen the immune system
(B) one can strengthen the immune system through deep relaxation, if it is practiced regularly
(C) the immune system can be strengthened as a result of deep relaxation if practiced regularly
(D) when deep relaxation is practiced regularly, the immune system can be strengthened
(E) when practiced regularly, the results of deep relaxation can be to strengthen the immune system
为什么B不对？？我觉得B的主语one才能yield啊

这题我也做错了，现在来重新整理下答题思路：
Besides yielding such psychological rewards as relief from stress, deep relaxation, if practiced regularly, can strengthen the immune system and produce a host of other physiological benefits.
(A) deep relaxation, if practiced regularly, can strengthen the immune system
(B) one can strengthen the immune system through deep relaxation, if it is practiced regularly
(C) the immune system can be strengthened as a result of deep relaxation if practiced regularly
(D) when deep relaxation is practiced regularly, the immune system can be strengthened
(E) when practiced regularly, the results of deep relaxation can be to strengthen the immune system

从后面的未划线部分produce来看，就知道划线部分的主语必须是produce动作的发出者。能够produce更多好处的，一定是物，不是人，首先就排除B和E（因为result不能produce）了。
剩下ACD的问题就是：究竟是immune system还是deep relaxation是动作的发出者呢？
接着往未划线部分的前半句看。能够从relief stress上yield的，免疫系统很明显做不到释放压力，能释放压力的只能是充分的放松（这个应该属于常识了吧。。。）
所以句意分析只有A了。

manhattan中给出的是 X and Y,当从句并列才用 X, and Y。这里并列的两个成分并不是句子，所以应该是X and Y，但由于插入了一个ing，才有X and，ing，Y。

关于逗号，其实逗号放在and后面更好，告诉读句子的人后边还有内容。而且不足于就因为这个而不选他，要从整句的意思决定

E 选项错哪儿了

同意2楼的答案与说明，

第一题，选项A里面的错误我在罗嗦下：

1, ",with the intention to"，逻辑主语是句子主语Alaska，与原意不符，不过似乎Alaska也说得通？
2, ",with the intention to"，和” after the exhaustion of its oil reserves“，不如动词简洁；
3, 就是its指代比较模糊；

选项D的错误，主要是after exhausting的逻辑主语不清楚，是句子主语Alaska还是紧邻的economy？如果改成C里面的被动语态，这个问题就解决了。

第一道题目,我研究了一下指代的问题,有一些个人理解,请大家来看看

c. 由于intended to ...after doing ...整个部分都是修饰fund,所以这个部分内的it的指代都是指代fund,所以指代的是fund,与逻辑相悖.
如果after从句并不从属于intended to...的这个修饰部分,则it指代主句主语(如果主语是单数的话)

你指的可是D)?

beside A, B
D E的immune system和前面的主语不对称
