Helr大神解释得很清楚了！
不过还有一个疑问，我做题的时候错选了C，理解的是乳浆草的milky sap让小牛长溃 ...

我是这样理解的 这句话的intended meaning应该是 a herbaceous plant 导致mouth sores和displaces grasses 而C选项having milky sap做noun modifier改变了强调的重点 前面的句意由原来的导致mouth sores变成了having milky sap 改变了句意 其次这句话并没有着重强调这个milky sap怎样特别 或者具有怎样的特性导致mouth sores 所以没有必要

最后还有一点不太确定 根据noun modifier原则 nouns and noun modifiers must be placed either right next to each other or very close together 这里把having放在Eurasia感觉可能会引起having修饰Eurasia的歧义?还是可以跳过介词指代名词呢？

triway

乳浆草导致牛生口疮，that定从跳跃修饰leafy spurge；然后rendering是整个主句的伴随状语表示immediate consequence，后果是grassland worthless，A好像在语法上好像是没啥问题，那就是比较多地考句意了，选了A，伤心

求问大神~答案中说D选项的displaces和renders是名词，没懂啊难道不是动词么~？ ...

同意！               

Mandy求一次过

A US have been invaded不能 displacing grasses 而是leafy spurge displacing 所以不能和rendering并列
B with milky sap是对herbaceous的插入语，不是对leafy spurge所以可以，后面的that都是对leafy spurge的修饰，rendering是对前面一句话的修饰。
C我觉得Helr老师的解释能够理解但是可能做题的时候并不一定能想到这一层，这里的that修饰的对象感觉算是比较明显的问题，因为that这样看既能修饰milky sap也能修饰herbaceous有指代不明的嫌疑
D 的那个renders 和displaces的是动词但是是单数动词应该是和前面gives做并列的属于从句的成分，所以前面的话没说完没动词。
个人看法而已

render 给予，使成为。我觉得可以把render 想成make
xxxxxx, rending sth.
等于 xxxxxx, making sth. 导致了这样的一个结果

首先先理一下这个句子要表达什么意思
5 million acres in US have been invaded by xx, rendering rangeland worthless
The plant gives mouth sores to ... and displaces.
逻辑上应该是
乳浆草的入侵让很多地没有价值
和
这种植物让牛染病并且取代原有植物
milky sap是乳状的汁液，逻辑上不应该是它被修饰，原意是强调乳浆草的危害

A。States have been invaded by leafy spurge, a herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle, displacing grasses and other cattle food and rendering  对乳浆草的描述逻辑关系有误，不是入侵取代了其他的植被，是乳浆草取代
B。States have been invaded by leafy spurge, a herbaceous plant from Eurasia, with milky sap, that gives mouth sores to cattle and displaces grasses and other cattle food, rendering 正确，见最开始逻辑分析

C。States have been invaded by leafy spurge, a herbaceous plant from Eurasia having milky sap that gives mouth sores to cattle and displacing grasses and other cattle food, rendering  gives和displacing Parallelism， 另外having milky sap使得that从句修饰milky sap

D。States, having been invaded by leafy spurge, a herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle, displaces grasses and other cattle food, and renders  逻辑关系，不是这个乳浆草让地没价值，是乳浆草的入侵

E。States, having been invaded by leafy spurge, a herbaceous plant from Eurasia that has milky sap giving mouth sores to cattle and displacing grasses and other cattle food, rendering  没有主语，逻辑关系，不应该是milky sap被修饰，整句听起来也很awkward

About 5 million acres in the United  States have been invaded by leafy spurge, a herbaceous plant f ...

看了你的回复瞬间懂了，3Q

请问diaplacing grasses…rendering…修饰的到底是前面哪句话呀？是About 5 million…还是a herbaceous plant…

啦啦噜啦啦

Ron 说过
clause 1, clause 2, ING

comma + ING 修饰clause 2

A. States have been invaded by leafy spurge, a herbaceous plant from Eurasia with milky sap that gives mouth sores to cattle, displacing grasses and other cattle food and rendering
在这里，displacing 和 rendering 都在 修饰 “that gives mouth sores to cattle" 这个句子，逻辑主语是 milky sap
和句子本身要表达的意思不一样，本身的逻辑主语 应该是 a herbaceous plant。

B. States have been invaded by leafy spurge, a herbaceous plant from Eurasia, with milky sap, that gives mouth sores to cattle and displaces grasses and other cattle food, rendering
前后都有逗号的modifier 可以直接忽略
所以就是 ：
a herbaceous plant from Eurasia that gives mouth sores to cattle and displaces grasses and other cattle food, rendering


noun1 + prep + noun2 that
that 可以修饰 noun1 或者  noun2 这里是 noun1 所以  give，displace，rendering的 逻辑主语都是 a herbaceous plant perfect

我来贡献一下我 2 cents

A, 逗号+ving ,displacing grasees 做Adverbial前面一个clause，主语是 milky sap，milky sap displace grases？没有意义；redering …worthless 是displacing grasses的结果，两个结构直接不应该只用and（没有表达结果的递进关系）

C, 根据逗号+Adverbial主语是前面clause的原则， milky sap render land worthless，这不是作者想表达的，应该是plant造成land worthless；"... and displacing grasses" is parallel to what, exactly? "Having milky sap", I guess? That's a mess，性质上不平行，一个在说固有属性，一个在说动作；

D, 如果displaces是acres动词，句子意思就有问题，也不满足逗号+and跟句子，所以主语 acres没有动词；it is illogical to say that 5 million acres displaces grasses and renders rangeland worthless.

E, 整句全是v-ing-participle (modifier)，没有动词
