本句若没有从句,通常顺序为His parents bought a candy store there(他父母在那里买了家糖果店);但是,由于后面有从句,若直接接上去的话会是His parents bought a candy store there which they ran for the next 40 years or so years,先行词与引导词分开了;若将there后置His parents bought a candy store which they ran for the next 40 years or so years there,也不是最合适,故将there至于句首是最合适的了。
故,there只是个地点状语。
1. 不算。there后跟动词才是倒装句,如:There stood a man about fifty.
2. there在这里作地点状语,表示在那里。
