that引导宾语从句的时候貌似可以省略（manhattan的知识点）摘自总结that的省略（功能相同或平行的情况下 ...

不是的，其他动词也可以有省略的情况，比如OG12的这一题，答案是选E的

As its sales of computer products have surpassed those of measuring instruments, the company has become increasingly willing to compete for the mass market sales they would in the past have conceded to rivals.
(A) they would in the past have conceded to rivals
(B) they would have conceded previously to their rivals
(C) that in the past would have been conceded previously to rivals
(D) it previously would have conceded to rivals in the past
(E) it would in the past have conceded to rivals

多谢您和LS几位的回复！我觉得他是想说that如果在两个从句里的成分不一样的时候，第二个that是不可以省略的，应该是既属于平行的问题，又属于that的省略的问题，DUKB24费心了---您说的完全是that的省略的问题----不过，我不是能完全理解为什么第二个that不能省略。。。。如果补出来，不是可以的吗？句子是通顺的。

that引导宾语从句的时候貌似可以省略（manhattan的知识点）

摘自总结
that的省略（功能相同或平行的情况下是可以省略的）：
basically, it's ok to omit "that" if the sentence is still legitimately parallel without it.
for instance:
food that is nutritious for cats but that is poisonous for dogs
food that is nutritious for cats but is poisonous for dogs
food that is nutritious for cats but poisonous for dogs
all correct.


hand signs that natives use and that appear in local rituals --> correct.
these are both that-clauses that modify "hand signs", so the parallel structure works.


BUT（一个做主语一个做宾语是不能省略that的！）
hand signs that natives use and appear in local rituals --> INCORRECT.
the second of these doesn't work because the right-hand component of the parallel structure is appear in local rituals (i.e., active verb whose subject is "hand signs"). there is no verb in the left-hand side that is parallel to this, so this makes no sense.


the only verb on the left is "use", which is NOT parallel to "appear" -- the former is something that natives do, while the latter is something that the hand signs do.

你应该是想说that引导定语从句做宾语的时候可以省略吧？that引导宾语从句的时候只有很少几个动词后面可以省略，如say， announce，其余的动词基本都不能省略。

多谢，我了了。那么，我们能不能说我们LS的LS错了呢。。。。

怎么说呢，他也没有错，他只是没看清楚说的是同位语从句, 他说的是同位语，估计是说这种形式：n1, n2+ that 这种同位语，that引导定语从句修饰前面的n2

嘿嘿。。LS的亲我还是挺同意你的。。。。那个LSDELS说的很搞笑，都同位语的that了，怎么还用到定语从句中了呢。。。无语。。。名词性从句that和定语从句that就是省不省略的关键啊。。。。。。

多谢！请问，同位语从句里面的that可以省略吗？

-- by 会员 slr257 (2012/10/1 1:26:56)

不能，that在同位语从句里不做任何成分，仅仅起引导同位语作用，但是不能省略。

要看that在同位语中的用法。 如果同位语中的that引导定语从句修饰前面的名词，则同定语从句用法一致。
