回答:一个句子必须有主语、谓语。从句也是句子,它跟主句一样也有主语、谓语。从句在句中可以作主语(主语从句)、状语(状语从句)、宾语(宾语从句)、表语(表语从句)、同位语(同位语从句)、定语(定语从句)。而非谓语动词(不定式、动名词、现在分词)则不能在句中作谓语。不定式在句中可以作主语、表语、宾语、定语、状语、宾补; 动名词在句中可以作主语、定语、宾语、表语、同位语; 分词(包括现在分词和过去分词)在句中可以作表语、定语、状语、宾补。故从句中必须有谓语,但并非必须有非谓语动词(有否非谓语动词跟谓语动词的用法有关,跟非谓语动词的用法有关。)。例如:
He is the man who I saw yesterday.
I know the man who is sitting in the chair watching TV.
英语从句中谓语动词的形式跟主语有关, 跟时态、语态有关。例如:
He says that Mary enjoys jogging in the morning.
The bridge which was built five years ago is 80 metres long.
He is the man who I saw yesterday.
I know the man who is sitting in the chair watching TV.
