Question

在英语中，关系代词能否充当定语从句中宾语从句的成分？

I have a dream that you think that I am difficult to fulfill.我有一个你认为我很难完成的梦想。
比如这个句子中，that充当了定语从句中宾语从句的宾语补足语，那这样可以吗？
是否还能够充当定语从句中宾语从句的主语呢？
比如：He has a pen that I think that is very beautiful.他有一支我认为非常漂亮的笔。i think that后是宾语从句，that只是宾语从句连接词。

Answer 1

不知道理论上是不是可以这样写，但实际使用中，我认为这两句话都不大会出现：
第一句貌似有些错误。I am difficult to fulfill a dream 本身不是一个合格的句子，正确说法应该是 It's difficult for me to fulfill the dream. 或 The dream is difficult for me to fulfill. 所以后面再变化也是不对的了。
第二句之所以别扭，是因为宾语从句的 that 不是必须写的，所以一般都会写成：He has a pen that I think is very beautiful. 这样是没错的。同理，改正后的第一句也是 I have a dream that you think is difficult for me fulfill.
如果要造一个为宾语从句里的宾语写定语从句的句子，那应该也行，比如 He has a pen that I think you like. 或 I have a dream that he thinks he has had too. 只不过凭语感看，都不适合把 that 写两遍。

Answer 2

He has a pen that I think that is very beautiful.
你这里的that 具有 那个 的意思 但是你说了是连接词 当连接词时 that 是没有意思的
所以句子中的that 连接的宾语从句缺少主词 it
He has a pen that I think that it is very beautiful.
宾语从句连接词 think, suppose, believe, presume, dare say 这种口语词时， that通常要省略。
He has a pen that I think it is very beautiful.
it 和 pen 重复了 把it 也省略了把

He has a pen that I think is very beautiful.
英语就是要精简而表达最多意思

引导定语从句的that作fulfill的宾语。

那第二句呢？先行词也可以做宾语从句中的主语？
