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

試題分析：句意：警告上寫著決不要讓化學(xué)物質(zhì)離火太近。under no circumstances決不；這里它放在句首句子用部分倒裝，故選C。
點評：本題難度適中。倒裝句是高中階段必須掌握的語法項目，它分為部分到裝和全部倒裝，情況復(fù)雜，需要考生熟記它們的用法。
即學(xué)即練：—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等否定副詞位于句首作狀語時，后面要用部分倒裝，再由句意可知，選B。
