Question

So mysteriously ______ missing that many puzzles wait to be solved.

A．did Flight MH370 go	B．Flight MH370 went
C．does Flight MH370 go	D．had Flight MH370 gone

Answer 1

A

解析试题分析：句意：MH370航班消失的是如此神秘以至于许多困惑有待解决。本题属于so+adj/adv.... that副词提前的倒装句中的一种特殊句式，排除B。因为Flight MH370消失发生在过去，故用一般过去时。故选A。
考点：考查倒装句。
