名词性定语从句的主从时态都必须一致吗？如果主句为过去时态从句时态也必须过去时态？

Question

如题所述

Answer 1

1. 定语从句不属于名词性从句。名词性从句主要有宾语从句、表语从句、同位语从句等。
2. 定语从句中主从句时态应根据具体句子而灵活变化。
如：a. I bought a book which was borrowed by my frien yesterday.（主从句时态一致）
b. I have a interesting book which was borrowed by my friend yesterday.（主从句时态不同）追问

如果主句是过去式从句是现在式有没可能

追答

可能。

如：This is my hometown where I lived several years ago.
（关系副词 where 在从句中作状语。）

追问

这个主句还不是现在时？

追答

Severa months ago, I lived in the house which don't belongs to me now.
（主句过去时，从句一般现在时，由主从句各自的时间状语可看出。）

追问

那名词性从句主从时态一致吗

追答

不一定。应视句子具体情况（时间状语等）而言。
