题目分析：
略
选项分析：
A选项：代词they没有指代对象。
B选项：Correct. 本选项在逻辑和语法上均是正确的。
C选项：fat of a kind需改为a kind of fat。a kind of是一个固定搭配，表示某一种，不能拆分。of a kind表示“同一类，相似的”，显然不符合本题的含义。另外，这里的that of略有赘余的嫌疑，虽然可以比较两种动物的脂肪，但比较两种动物已经足够清楚，所以这个that of可以不必要添加。
D选项：比较对象不对等，应该比较的是野生动物和家养动物。fat of a kind需改为a kind of fat错误同选项(C)。
E选项：代词they的指代错误同(A)。fat is of a kind错误原理同选项(C)。
看了解释还是觉得B选项wild animals have less total fat than livestock有歧义。
98题的SC216
plants are more efficient than fungi at acquiring carbon是正确选项
plants are more efficient at acquiring carbon than fungi
解释里排除的原因是at acquiring carbon的插入语位置不对，容易误解为plants are more efficient at acquiring carbon than acquiring than fungi
想不明白
这个题目选择B的原因是因为A和C在比较上都有硬伤。比如C吧，应该写成：
wild animals' total fat is less than that of livestock.
这样才是一个正确的表达方式。
一开始就斩钉截铁的排除了B。。。能不能理解为选项里有两个主干相同只有插入语前后不一致的，就可以用这个点来排除一个。这道题这种的选项就不是这个考点了
我其实没太理解这个插入语是怎么排除的。。
就是做完98题的SC216之后就觉得插入语的位置很重要了。。。如果我理解错了，请告诉我。。。
