英语长难句分析.
For example,given the current position of the Pacific Plate,Hawaii is above the Pacific Ocean hot spot.So the position of the Pacific Plate 50 million years ago can be determined by moving it such that a 50-million-year-old volcano in the hot-spot trail sits at the location of Hawaii today.
尤其是这一段的“ by moving it such that a 50-million-year-old volcano in the hot-spot trail sits at the location of Hawaii today.”这里的such that怎么解释?
还有“sits”怎么这里又有一个谓语?
