In some species of cricket, the number of chirps per minute used by the male for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve as an approximate thermometer.
(A) for attracting females rise and fall in accordance with the surrounding temperature, and they can in fact serve
(B) for attracting females rises and falls in accordance with the surrounding temperature, which can in fact serve
(C) in attracting females rise and fall in accordance with the surrounding temperature, in fact possibly serving
(D) to attract females rises and falls in accordance with the surrounding temperature, and it can in fact serve
(E) to attract females rises and falls in accordance with the surrounding temperature, in fact possibly serving
答案无争议，是D。但我只是想问，究竟分词短语结构位于句尾，逻辑主语规律是什么呢？
这里的E中的serving，如果除去possibly的错误，应该是谁做主语？
白勇的书是写，现在分词ing位于句尾，一般是主句主语做逻辑主语（若表示因果则无逻辑主语）
过去分词ed位于句尾，则是就近找名词做逻辑主语
但我记得在做题时，也碰到ing结构放在句尾，但逻辑主语是前面整个句子的
请问各位，总结后的规律是怎样呢？因为我觉得E的serving，主语可以是number，也可以是前面的主句。。
一．现在分词
1）现在分词作状语：
现在分词位于句末或句首，前后有“，”将其与主句隔开，则现在分词优先做主句谓语的伴随状语，伴随动作方式，动作本身以及动作结果。一般不倾向于用现在分词
短语前后加“，”放在句子中间作状语的用法。（lstzhang：分词不是放在头部，就是放在尾部，不要放在中间。如果现在分词位于一个从句中的开头部
分，现在分词短语也可以作分句的状语。）
如果现在分词前有介词或连词引导，如after, while, by等，则现在分词作状语。
▲现在分词作状语放在句末，按照接近性原则，应优先修饰靠近它的谓语，这个谓语可能不是主句的谓语。同理，按照接近性原则，伴随状语修饰谓语，放在句末会比较接近谓语，而放在句首，中间隔着主语去修饰谓语，离得远，不好。

fund, with the intention to sustain the state’s economy after the exhaustion of its oil reserves.
(C) fund intended to sustain the state’s economy after oil reserves are exhausted.
(D) fund intended to sustain the state’s economy after exhausting its oil reserves.
D项中，after exhausting 这个现在分词短语从语法上讲就应该修饰sustain这个动作，从而造成逻辑主语的错误。所以不选。
▲分词放在句首，暗示着这个动作发生在谓语动作之前，先有分词的动作，再有谓语的动作。前后脚关系。
这里考的是过去分词与现在分词并列作定语修饰前面名词的法，因为已经有了过去分词在前，避免了与其并列的现在分词作状语的可能。
2）现在分词作定语：如果现在分词前面没有“，”现在分词优先作定语修饰前面的名词。
特例：补充材料335 The growth of he railroads led to the abolition of local times, which was determined by when the sun reached the observer’s meridian and differing from city to city, and to the establishment of regional times.
(C) which were determined by when the sun reached the observer’s meridian and differing
(D) determined by when the sun reached the observer’s meridian and differed
(E) determined by when the sun reached the observer’s meridian and differing
A．现在分词作定语表示长期，反复的动作，表示该动作是名词永久属性，常用来表示法令或权力的内容。与定语从句表示的具体，一次性动作有意义上的区别。
B．如果定语从句带有情态动词，或者定语从句表示的时态与现在分词不一致时，现在分词不能取代定语从句作定语。
二．过去分词
过去分词位于句首，修饰主语。
位于句中或句尾，优先作定语修饰前面的名词；
过去分词位于句尾，如果紧接着谓语，则过去分词也可作状语，需要根据具体情况从逻辑上判断。
LZMP123NO.37 Traveling the back roads of
(C) in 1905, Bela Bartok and Zooltan Kodaly began their pioneering work in ethnomusicology, traveling the back roads of Hungary armed only
(D) having traveled the back roads of Hungary ,in 1905 Bela Bartok and Zooltan Kodaly began their pioneering work in ethnomusicology; they were only armed

三．介词短语：
介词短语应紧跟被修饰对象
在GMAT语法中，对于介词短语的考点主要就是介词短语的位置，介词短语的位置不同，其修饰对象也不同，其作状语或定语的语法功能也不同。
1）位于句首，修饰主语或作全句状语；
2）位于句尾或句中，则要看它前面的词是名词还是谓语，是名词则优先作定语，是谓语则优先作状语。作状语时，介词短语的位置一定要离谓语比较近，具体情况还要根据逻辑意思分析。
例题：补充材料144
The Forbidden City in Beijing, from which the emperors ruled by heavenly mandate, was a site which a commoner or foreigner could not enter without any permission, on pain of death.
(C) which no commoner or foreigner could enter without permission,
(D) which, without permission, neither commoner or foreigner could only enter,
“without+名词”这一介词短语紧跟谓语，则作状语表条件（意为“如果没有”），修饰谓语。
例题：（来源 Kaplan语法小测验）
2. The principal has sought approval for her plan to grant promotions to only those seven-grade students proficient in reading without meeting with opposition.
(C) reading, without the opposition of others
(D) reading, and has not met with opposition
“without＋the opposition of others” 短语如果作状语，远离所要修饰的谓语，作状语或作定语作用不明，不好。
补充材料124 Alaska regularly deposits some of its profits from the sale of oil into a special fund, with the intention to sustain the state’s economy after the exhaustion of its oil reserves.
(A) fund, with the intention to sustain the state’s economy after the exhaustion of its oil reserves.
(C) fund intended to sustain the state’s economy after oil reserves are exhausted.
intended作定语，修饰fund。
逻辑主语也是fund。
楼上的mm，这些总结的来源是？
谢
顶一下，期望nn解答
但做题的时候是需要自己去判断做定语、状语还是插入语的。。。所以这样分类。。。
我总结的就是放句尾，没有逗号修饰前一个名词，有逗号的话就自己看着办了，都有可能（修饰前一个名词，修饰前面整个句子，修饰前面句子主语）
