It was pretty hard for him to bring up the child on his own.

问题描述:

It was pretty hard for him to bring up the child on his own.
这句中主语部分是[on his own]谓语部分是[was] 这是个形式主语的句子,但我区分不了这句的主谓宾... 请高手详细讲一下怎么区分主谓宾...[详细点]...

It+be动词+形容词+for sb.+to do sth.句型中,to do sth.做真实主语,it做形式主语,所以这句话中to bring up the child是真实主语,it是形式主语.was pretty hard 是谓语.for him 是宾语.
