定语从句（形容词性从句）和宾语从句（名词性从句）都是从句的一种，在这里简单介绍，若想了解详细内容，可以看我博客之前的章节。

定语从句：定语从句是用来修饰一个名词或代词的从句，通常紧跟在先行词后面，用来对先行词进行进一步的说明或描述。定语从句通常由关系代词（如who, whom, whose, that, which等）或关系副词（如where, when, why等）引导。

例如：

• The book that I bought yesterday is very interesting.（我昨天买的那本书非常有趣。）
• The girl who is sitting next to me is my friend.（坐在我旁边的女孩是我的朋友。）

宾语从句：宾语从句是用来作为主句中的宾语的从句，通常由连接词（如that, whether, if等）引导。宾语从句通常用来表示某种行为、感受、想法或认识等。

例如：

• I don’t know what time it is.（我不知道现在是几点。）
• She asked if I could help her with her homework.（她问我能否帮她做作业。）

总之，定语从句和宾语从句都是从句的一种，它们的作用和引导方式有所不同。

定从which & 宾从what的区别

定语从句中which连接词指代先行词的事物或物品，用来修饰先行词。例如：

• The book, which I bought yesterday, is very interesting.（我昨天买的那本书非常有趣。）

这里的which指代先行词the book，用来修饰它。

而宾语从句中what连接词则用来引导一个宾语从句，表示从句的内容或信息。例如：

• I don’t know what time it is.（我不知道现在是几点。）

这里的what引导宾语从句，表示先行词的内容“现在是几点”。

因此，定语从句中which连接词和宾语从句中what连接词的区别在于，which用来修饰先行词，而what用来表示从句的内容或信息。
