Question

he arrived in New York in 1990,______some time later,he became a computer engineer.
a.when b.where c.that d.what
为什么选b 具体点

Answer 1

陷阱选项是a因为后面有"some time later过了一段时间后",所以1990不能成为先行词,否则你说在1990he became a computer engineer,又说some time later he became a computer engineer,自相矛盾,于是先行词只能是前一个名词New York ,在从句中做地点状语.
