2 Reserchers have questioned the use of costly and experimental diagnostic tests to identify food allergies ,such as milk ,that supposedly disrupt normal behavior.

 A to identify food allergies ,such as

B to identify food allergies ,like

C to identify food allergies.such as to

D for identifying food allergies ,like that of

E for identifying food allergies ,such as for

为什么是C啊?还有A错在哪里啊???谢谢

such as (the food allergy) to milk  A里面没有to 就成了milk 和　allergy 是同一概念　所以不行

abort

why not E？

harriethan

对某物过敏 固定搭配 allergy to something

abort

是因为是allergy to sth.所以用such as to milk么？
我觉得好像用to是因为句子要表达的是the use of tests的目的，如果表达的是the use的用途就用for了，而后面的to是跟前面的to对应？不知道是这样么？

vict2006

还是不很清楚啊......哪位高手能详细解答下不???谢谢

二楼的MM解的真好

such as 后一般接Ｎ或者doing，接to时只有两种可能一是错了，二是有省略

诚如二楼所说，乍一看还真蒙住了

我有个另外的问题，that supposedly ----为何that 前面还有逗号呢，这个that 指的是什莫呢

puremilk1120

在GMAT中，to identify> for identifying，就是说动词的优先性最高

根据新东方讲义， 动词》形容词》抽象名词》分词动名词》从句

定从修饰插入语前名词
