分析下句子结构
they took tests that measured a variety of different factors known to be involved in heart disease,blood pressure and blood levels.

Answer 1

they took tests that measured a variety of different factors known to be involved in heart disease,blood pressure and blood levels.
参考译文：他们参加了考试,这些考试旨在测试 “众所周知的” 涉及到心脏病,血压,和血浓度含量标准等各种不同的因素.
分析句子：主句是“they took tests.其它都是从句部分 .”that measured a variety of different factors是定语从句修饰前面的名词“tests”,known to be involved in heart disease,blood pressure and blood levels 这是一个含有过去分词的大短语,修饰前面的名词“factors”,假如把这个过去分词短语转换成句子的主动结构就是：people know the factors to be involved in heart disease,blood pressure and blood levels【意思是：人们知道这些因素涉及到心脏病,血压,和血浓度含量标准.to be involved in...是不定式短语,意思是“涉及到.",这个不定式短语做该句子的宾语（factors）的宾语补足语.我们不妨把结构“A knows B to be C 的意思理解成：A知道（或者意识到）B是C .我非常详细地解释清楚了.确保译文和分析正确,
