Question

The subject which he is interested is English.分析本句定语从句是什么,is English的成分是什么?

Answer 1

首先,我负责任地指出,你所问的句子是个错句.此句应写为：
The subject which he is interested in is English.或
The subject in which he is interested is English.
本句是一个含有定语从句的复合句.其中,The subject is English是主句,而which he is interested in为一个句子作定语,即定语从句,修饰先行词the subject.
故该句可译为：他感兴趣的科目是英语.
