英语简单语法问题，求大神帮忙

勾画那里的怎么语法分析啊 that充当从句什么成分呢？

Answer 1

that 引起的是一个定语从句(the researcher claimed were from a previous experiment),这个定语从句中，主语the researcher, 谓语 claimed, 关系代词that 代替a pile of pens 作claimed后面宾语从句的主语，were是宾语从句的系动词谓语，from a previous experiment是介词短语作表语。为了便于你理解，我把这个定语从句改写成:The researcher claimed a pile of pens were from a previous experiment.

Answer 2

你好, that引导定语从句, 指代 a pile of pens 一堆笔, 后面的从句补充说明这堆笔, 从句的顺序相当于 the researchers
claimed the pile of pens were from
a previous experiment. 即 研究人员声称这些笔来自之前的实验。
把句子拆开来break down the
sentence, 就很好理解了。希采纳！

Answer 3

可以这么理解:pens后面有that引导的两个定语从句，
第一个是that the researcher claimed
第二个是that were from a previous experiment
这两个定语从句公用一个that
就是that the researcher claimed were from a previous experiment.

Answer 4

that从句用来修饰前面的pens
充当定语 为that引导的定语从句
