Question

There is a possibility that these hens could be frightened and lay fewer eggs       a sudden loud noise.

A．should there be	B．there was
C．would there be	D．there having been

Answer 1

A

試題分析：考查虛擬語氣中的倒裝。根據(jù)語意，原句應(yīng)為…if there should be a sudden loud noise，if虛擬條件句中有should時，可以把if省略，should提前，變成should there be 結(jié)構(gòu)，據(jù)此選A.
點評：if的非真實條件句，可以用省略倒裝句，省略if，將should，were，had提前，意思是一樣的，就是更簡潔。
