Today Egyptologist Chrisnaunton travels here to investigate what triggered over a thousand years of pyramid building.
1)travel是及物还是不及物用法,例如travel Shanghai 还是 travel to Shanghai ?
2) what triggered over a thousand years of pyramid building. - over a thousand years of pyramid building. 这怎么理解成分和结构以及意思?
Today Egyptologist Chrisnaunton travels here to investigate what triggered over a thousand years of pyramid building.
1. 本句,travel 是不及物动词,后面没有宾语。它可以及物可以不及物,区别是:
travel Shanghai 游历/游览上海
travel to Shanghai 旅行到/去上海
2. what triggered over a thousand years of pyramid building.
what 是连接代词,引导的是“间接疑问句”。trigger,及物动词“引发,导致”,宾语是over a thousand years of pyramid building。宾语的结构是:
...years of doing(动名词)。举例:“三年多的写作”,over three years of writing。
3. what triggered over a thousand years of pyramid building. 是什么引发了一千多年的金字塔建造。
