Question

the technology they introduced meant that metal and leather goods were produced there for the first time.
请问：其中"they introduced"用于修饰"the technology",那这里的"meant that"在这里怎么理解呢,还有"meant"为什么要用过去式呢?

Answer 1

这里的"meant that"在这里怎么理解呢,还有"meant"为什么要用过去式呢?
mean that...意味着...（mean 后面跟的是从句）
meant用过去时,是因为这个句子的背景就是过去,看前面的 introduced 和后面的 were produced就知道了.
