Question

Watch out for these animals! They could be terrified ______ a sudden loud noise．

A．being there	B．should there be
C．there was	D．there have been

Answer 1

B

试题分析：考查虚拟语气，should there be="if" there should be,句子意思“小心这些动物，如果突然有大的声音，它们很可能令人害怕”，所以选B
点评：虚拟语气是个难点，做题时要注意，固定句型should there be="if" there should be意思“如果有”，固定词组Watch out意思“小心”。
