请问这句英语中的某段是什么短语?
He helped popularize the idea that some diseases not previously thought to have a bacterial cause were actually infections,which aroused much controversy when it was first suggesed.
这段话中的“ some diseases not previously thought to have a bacterial cause” 属于什么类型的短语?

Answer 1

在that引出的从句中,diseases是主语,由some修饰,后面又有定语短语修饰,是由原来的定语从句省略而成的,原来的定语从句时这样写的：some diseases that were not previously thought to have a bacterial cause.指所以省略,就是为了避免出现两个that及其引出的两个从句,而且句子变简练后,也显得层次更高.
你之要熟悉后,多点留意观察和模仿,以后自己也能写出这样漂亮的句子了.
