加拿大商科研究生GMAT语法比较对象问题解析
加拿大商科研究生考试，我们知道GMAT中涉及到比较的题目是很多的，也是很多同学容易做错的题目，今天我们就来讲讲比较中涉及到比较对象的问题。加拿大商科研究生
1.比较对象概念对等
人、事、物对比人、事、物，可能比较特征、性质、行为、数量等
例句
I ate more apples than Tom was.
这个句子很明显就是错的，把“做了什么”和“是什么”做了对比
我们可以改为：
I ate more apples than Tom(did).
I ate more apples than did Tom.
这两个句子都是对的
2.发现比较的标志词，找到比较对象
like，unlike,as,
形容词／副词的比较级+than
compared to/with,in contrast to/with+具体化名词，on the contrary,opposite to/of,
as/so…as
be overshadowed by,be different from
3.替代原则
与比较对象重复的不可数名词或者单数名词，用that代替；
与比较对象重复的复数名词形式，用those代替
我们来看一个例句
野生动物wild animals的总脂肪比牲畜livestock的总脂肪少。此句话对比的是总脂肪，所以应该是：
The total fat of wild animals is less than that of livestock.
不像小蜜蜂的巢，大黄蜂的巢有很多装饰物。
Unlike those of honeybees,the nests of yellow jackets have many decorations.
此题的对比对象就是两类巢
Unlike those of honeybees,the nests of yellow jackets have many decorations.

下面我们再来看两个具体的题目：
1.As contrasted with the honeybee,the yellow jacket can sting repeatedly without dying and carries a potent venom that can cause intense pain.
(A)As contrasted with the honeybee,
(B)In contrast to the honeybee’s,
(C)Unlike the sting of the honeybee,
(D)Unlike that of the honeybee,
(E)Unlike the honeybee,
答案是E,对比对象是honeybee和the yellow jacket
2.The eyes of the elephant seal adapt to darkness more quickly than any other animal yet tested,thus allowing it to hunt efficiently under the gloomy黑暗的conditions at its feeding depth of between 300 and 700 meters.
A.The eyes of the elephant seal adapt to darkness more quickly than any other animal yet tested,thus allowing it
B.The eyes of the elephant seal adapt to darkness more quickly than does any other animal yet tested,allowing them
C.The eyes of the elephant seal adapt to darkness more quickly than do those of any other animal yet tested,allowing it
D.Because they adapt to darkness more quickly than any other animal yet tested,the eyes of the elephant seat allow it
E.Because the eyes of the elephant seal adapt to darkness more quickly than do those of any other animal yet tested,it allows them
此题正确答案是C，对比对象是海象的眼睛和其他动物的眼睛，a和b选项对比对象不一致；d选项中they代指的是主句中的主语the eyes，对比对象还是不一致；e选项前半部分是对的，后面的it allows them有问题，首先it不能代指前面一句话的内容，其次them错误，本意上指的是the elephant seal
3.A group of paleontologists recently announced that a site in Utah has yielded fossils of some of the biggest armored dinosaurs ever found,and they are at least 25 million years older than those of any similar dinosaur type that previously was found in North America.
A.and they are at least 25 million years older than those of any similar dinosaur type that previously was
B.and that they were at least 25 million years older than any similar dinosaur type previously
C.and the fossils are at least 25 million years older than any similar dinosaur types that previously were
D.fossils that are at least 25 million years older than those of any similar dinosaur type previously
E.fossils at least 25 million years older than similar dinosaur types that were previously
此题答案是D
首先从句意上要搞清楚的是相似类型的恐龙化石在北美被发现，而不是恐龙在北美被发现，所以比较对象是Utah的恐龙化石和之前在北美被发现的相似类型的恐龙化石,根据比较对象不一致，排除BCE,还剩下A和D,A选项中的they有指代歧义，并且后面的was一定是错的，因为that代指的是those。GMAT语法
比较对象一致是涉及到比较的题目首先要考虑到的点，这并不是很难的点，只需要我们做题的时候多加留意就可以了。
