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。

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。

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.

补充材料136 The labor agreement permits staff reductions through attrition with increased pension benefits and a special early-retirement program for speeding it up.
(A) attrition with increased pension benefits and a special early-retirement program for speeding it up.
(B) attrition and provides increased pension benefits and a special early-retirement program to speed the attrition process.
这类题在真题中的例题很多,如果发现介词短语所修饰的对象不合理,则应该改变介词短语的位置。
