Question

谁能给我解答一下这段英语的句型结构。

They explained the conditions under which ordinary people are willing to cause pain to their fellow human beings for the sake of following orders.

Answer 1

这句话是个复合句。they是主句的主语，explained 是谓语动词，the conditions 是explained 的宾语。“under which。。。following orders”是个定语从句，修饰先行词“the conditions”。为什么用“under”是因为这个固定搭配“under。。。conditions”。在这个定语从句中，ordinary people是主语，be willing to cause pain to their fellow human beings 是谓语部分，for the sake of following orders 是目的状语。

Answer 2

They主语
explained 谓语
the conditions 宾语
under which ordinary people are willing to cause pain to their fellow human beings for the sake of following orders.修饰宾语的定语
under which 此处which指the conditions 。
are willing to cause pain to their fellow human beings 定语从句的谓语部分，意思为：乐意造成他们同伴们的痛苦
for the sake of following orders是宾语从句的目的状语，意为：为了遵从秩序/服从命令/规则

Answer 3

句子主干为：They （主语）+ explained （谓语）+ the conditions （宾语），后面的是修饰宾语的后置定语。
参考翻译，要结合上下文来翻译：他们解释了在什么情况下为了遵守命令，普通人不惜对同类造成伤害。

Answer 4

They explained t he conditions under which ordinary people are willing to cause pain to their fellow human beings for the sake of following orders.They explained后面的做explain的宾语，然后后面那又有一个从句，是同位语从句，解释t he conditions
