 你说得对,v-ed modifier和v-ing是不一样的,是noun modifier.<br /><br />from Ron      <br />http://www.manhattangmat.com/forums/building-on-civilizations-that-preceded-them-in-coastal-peru-t8434.html  <br /><br /><span style="color:#d40a00;"><span style="background-color:#fef4c4;">past participles function as adjectives; they ALWAYS modify nouns.  it's actually impossible for a past participle to modify a whole clause.</span></span><br /><br /><span style="color:#d40a00;">you're thinking of the rule for "clause + , + -ING", which doesn't extend to past participles.</span><br /><br /><br />from Mitch    http://www.beatthegmat.com/sentence-correction-parallelism-og-q28-t86697.html<br /><br /><em>Based</em> does in fact modify <em>society</em>.<br /><br /><span style="background-color:#feed9b;">NOUN + PAST PARTICIPLE (with no intervening comma) </span>is used when the past participle modifier is needed to <span style="background-color:#feed9b;">define</span> the noun that it modifies:<br /><br /><strong>The Mohica developed a society based on the cultivation of crops.</strong><br /><br />What kind of society?  A society <em>based on the cultivation of crops</em>.  Since the past participle modifier is defining the kind of society being discussed, it is not preceded by a comma. <br /><br /><span style="background-color:#feed9b;">NOUN + COMMA + PAST PARTICIPLE</span> is used when the past participle modifier <span style="background-color:#feed9b;">does NOT define the noun that it modifies but simply provides additional information</span>:<br /><br /><strong>The Mohica developed their own elaborate society, based on the cultivation of crops...</strong><br /><br />What kind of society?  THEIR OWN ELABORATE society.  We don't need an additional modifier to define what society is being discussed.  Since the past participle modifier does not define the society but only provides additional information about the society, it is preceded by a comma.<br /><br />In less formal writing, a comma might be inserted before a past participle in order to indicate that the past participle refers to an earlier noun in the sentence:<br /><br /><strong>John entered the room, exhausted.</strong><br /><br />In the sentence above, the comma is used to indicate that <em>exhausted</em> refers not to the <em>room</em> but to <em>John</em>.  This sort of construction is unlikely to appear in an OA.  <span style="background-color:#feed9b;">On the GMAT, NOUN + COMMA + PAST PARTICIPLE generally will be used when the past participle provides non-defining information about the immediately preceding noun.</span><br /><br /><br />关于v-ing的几种考法,这个讨论也值得看:<br />http://www.beatthegmat.com/ing-modifier-three-different-versions-in-og-t38943.html<br />针对有同学提到的OG56,Stacey在这里也提到了:<br />An "-ed" modifier is a noun modifier, not an adverbial modifier, and should modify the <span style="background-color:#feed9b;">closest primary noun preceding it</span> (in the "comma -ed" setup).<br /><br /><br /><br /><br />

 baby姐,你好,看完讨论后对ving的用法清晰了很,再次感谢。有一个疑问过去分词修饰的时候与v-ing是不一样的吗?也就是说只能就近修饰前面的名词吗?<br />例如:OG 12 28题,<br />Building on civilizations that preceded them in coastal Peru, the Mochica developed their own elaborate society, <strong>based on</strong> the cultivation of such crops like corn and beans, the harvesting of fish and shellfish, and the exploiting other wild and domestic resources.<br />这里的就是只能修饰society而不能修饰Mochica的对吗?<div style="text-align:right;">-- by 会员 <u>Royzhang0929</u> (2012/2/13 9:49:08)</div><br /><br /><br />

 Baby 姐~刚刚发现一个反例,或者应用n, ved, ved 修饰最近名词不那么完美的例子~~~翻之前的帖好像没有人提过。OG 5 Diabetes, together with its serious complications, ranks as the nation's third leading cause of death, surpassed only by heart disease and cancer.这里的surpassed 肯定不是修饰最近的death的,如果要用ved 是noun-modifier这一规则,就是修饰的the nation's third leading cause of death? 包括像which这种也有好多类似的跳过了一些成分,最常见的是跳过短的介宾结构,去修饰介宾结构修饰的词,这里是一样的么?<div style="text-align:right;">-- by 会员 <u>feathsea8</u> (2012/4/16 15:53:14)</div><br />
 </div>
 <br />这题不是例外。<br />这题"surpassed only by ..."修饰"the nation's third leading cause of death",而"ranks as"相当于等号,因此<br />Diabetes = the nation's third leading cause of death,surpassed only by ...<br />也就是说,你也可以理解为"surpassed only by ..."修饰diabetes.<br /><br />你提到的这个,问题的关键就是:<br />A of B, (noun modifier)<br />这后面的noun modifier可以修饰B,也可以修饰"A of B",根据句意逻辑来决定<br />这点Ron讲过很多次,我以前也讨论过,你可以搜下。
