答案为E D中少了that,想问下that在从句中做主语时可否有that is..and is....在这种情况下是否也许不出才能平行？

如果出现这样的句子I have something to tell you that......and that.....这第二个that一定要出现吗？找这道题D的解释来看，是要的，为了平行。有nn解释下吗？

我觉得 为了保证平行修饰的层次不产生歧义 应该是要加that OG 好像有因为没有加that而错得题吧！

他觉得用定语从句wordy  可是解释中就提到了   第二个that应该不出来 可是我觉得 很不理解 定语从句的 that 为什么要补出来，，
