Question

_____,she went back to her room.
a.there wasno cause for alarm
b.being no cause for alarm
c.without having cause for alarm
d.there being no cause for alarm

Answer 1

答案：D.
1.答案如果选A,则逗号前后是两个单句,但是缺少连词如because/so等连接；
2.答案如果选B,则要求be no cause for alarm的逻辑主语必须是句子的主语she,句意根本不通顺：人不可能是什么的起因；
3.答案如果选C,同样要求without having cause for alarm是句子主语she的伴随状态,句意同B一样不通顺；
4.答案D为独立主格结构,做句子的（原因）状语,且be no cause ofr alarm的逻辑主语并不是句子主语she,而且其前的独立主语there,两者构成there be句型,为正确答案.
