原题：
Researchers now regard interferon as not a single substance, but it is rather a biological family of complex molecules that play an important, though not entirely defined, role in the immune system.
A as not a single substance, but it is rather a biological family of complex molecules that play
B as not a single substance but as a biological family of complex molecules playing
C not as a single substance but as a biological family of complex molecules that play
D not to be a single substance but rather a biological family of complex molecules playing
E not as a single substance but instead as being a biological family of complex molecules that play

请问大神最后用 that play和playing有什么区别嘛？还是都可以？
看OG和网上分析选项都没有提到这一点，求助！

OG的确没涉及这里that play 和playing哪样更好，以OG为准吧，两样应该都可以。

这个题的主要考点在句子的对称上，regard sth not as a... but as a... 或者 regard sth as not a... but a... 才是正确的句式。另外这里是用 that来引导一个定语从句来修饰前面的名词，更符合英语的习惯。
