关于定语从句没有谓语的问题

We need to have actual knowledge on which to base our thinking.

第一个句子为什么定语从句只有不定式没有谓语动词?

we need to have actual knowledge which to base on our thinking.

第二个句子也是,为什么都是to开头的?

We need to have actual knowledge on which to base our thinking.

网友知道这个词组吗?

base A on B:把 A 建立在 B 的基础上

1. 我们造句,用 what 提问 B:

What do you base A on?

2. 把这个直接疑问句变成间接疑问句:

I don't know what you base A on?

3. 我们用定语从句造句:“我们需要有实际的知识来作为我们思考的基础。”

We need to have actual knowledge which we base our thinking on.

4. 把 on 提到 which 之前:

We need to have actual knowledge on which we base our thinking.

5. 我们用不定式简化这个定语从句:

We need to have actual knowledge on which to base our thinking.

6. 即可得到网友的这个句子!

We need to have actual knowledge on which to base our thinking. (正确)

介词+which+to do作定语,为带关系代词的不定式短语,不再是定语从句。

We need to have actual knowledge which to base on our thinking.(错误)

We need to have actual knowledge to base our thinking on. (正确)

学无止境

1.We need to have actual knowledge on which we base our thinking.

根据:“介词+关系代词”引导的定语从句转化成为“介词+关系代词或副词+不定式”。可以将上面的句子改成:

2.We need to have actual knowledge on which to base our thinking.

3.we need to have actual knowledge which to base on our thinking.

当然根据动词不定式作后置定语也可以改成:

4.We need to have actual knowledge to base our thinking on./ to base on our thinking.

所以你问的问题不存在,转换成了另一种结构,不再是从句了。
