题目分析：
本题长度较长，但难度不算大。大概意思为：
有很多美国的土地被乳浆草侵占了。乳浆草是一个从Eurasia来的草本植物。这个草本植物让小牛长了口腔溃疡并且代替了草和其它的小牛食物，让牧场一文不值。
选项分析：
A选项：划线部分最后的分词短语displacing grasses and other cattle food是a herbaceous plant gives mouth sores to cattle的伴随状语。但在逻辑上，由于“长口腔溃疡”和“代替草和其它的小牛食物”是乳浆草的两个方面事情，之间没有逻辑关系，因此，两者应该用并列句来表示，不能让一者为另一者的伴随状语（若是伴随状语，则两者变为了修饰关系）。
另外，displace句和render句之间应用修饰关系而不是并列关系。这是因为，代替了草和其它的小牛食物的结果是“让牧场一文不值（render rangeland worthless）”。
B选项：Correct. 本选项在语法和逻辑上均是正确的。
C选项：按照本选项的语法结构，having milky sap that gives mouth sores to cattle和displacing grasses and other cattle food是并列关系，但在逻辑上，两者不能并列。拥有 milky sap是这个草本植物的固有属性（无论这个草在哪里），而“代替草和其它的小牛食物”是这个草本植物入侵美国后的结果。
D选项：本选项缺少谓语动词。选项末的displaces和renders均为单数动词，不可能作为复数名词about 5 million acres in the United States的谓语动词。
E选项：本选项缺少谓语动词。
A:In this official sentence, the comma + verb-ing modifiers displacing and rendering illogically modifies the preceding action gives by presenting the result of this action. Grasses and other cattle food are not displaced and rangeland are not rendered worthless because leafy spurge gives mouth sores to cattle.
