Question

The “Warning” reads: “Under no circumstances _____ be kept near fire!”

A．the chemical should	B．the chemical shouldn’t
C．should the chemical	D．should the chemical not

Answer 1

C

试题分析：句意：警告上写着决不要让化学物质离火太近。under no circumstances决不；这里它放在句首句子用部分倒装，故选C。
点评：本题难度适中。倒装句是高中阶段必须掌握的语法项目，它分为部分到装和全部倒装，情况复杂，需要考生熟记它们的用法。
即学即练：—How was the weather then?
—Hardly_____off the plane，when it started to rain.
A.I had stepped                 B.had I stepped
C.I stepped                      D.did I step
解析:B。hardly, seldom等否定副词位于句首作状语时，后面要用部分倒装，再由句意可知，选B。
