主语补足语怎样分辨？

## 学生提问 Such an area included the county in which the central city is located, and adjacent counties that are found to be metropolitan in character and economically and socially integrated with the county of the central city.这 段话中 and socially integrated with the county of the central city 是做什么成分？是和that are found to be 连在一起做主语补足语吗？ ## 权威解答 在 that are found to be metropolitan in character and economically and socially integrated with the county of the central city 这个定语从句中，to be metropolitan in character 和 economically and socially integrated with the county of the central city 都是做了主语补足语，中间用并列连接词 and 进行了连接。 ## 知识点梳理 （一）主语 主语是句子陈述的对象，说明是谁或什么，表示句子说的是"什么人"或"什么事"。 ① <u>My school</u> is not far from my house. ② <u>To do such a job</u> needs more knowledge. （二）主语补足语 在被动语态中，原来的宾语补足语变成主语补足语。 ① The dog is called Karl. ② The door was painted white.
