在英语里,一个句子只能有一个谓语动词除非各动词是并列或者用非谓语动词和从句来解决.这是一个很重要的语法点,如果你看不懂一定要搞懂.这里的open不是动词原形而是形容词（open有形容词词性）表示开着的状态.

hear是感官动词，与feel，smell等词用法相似，后面都接形容词，用来修饰宾语的状态。

she heard the front door open有语法问题，heard在这是不及物动词，后面不可直接接宾语，如接宾语需用介词连接，即heard of.
为什么不用was opened,是因为open在这里是不及物动词（从其后面没接宾语也可看出来），所以没有被动语态。

hear sth. do

没有问题听到门开了 hear sth. do 用动词原形做宾语补足语。
门开了，不必要是be opened 如： The door opened and in came the professor with his students.
