答案是选C,为什么啊!这个be,什么时候用.

为你提供精确解答
此题选【C】
这里是一个独立主格的用法,当主句和从句主语不一样时,从句变为非谓语的话,其主语要加上,也就是这里的there,being no cause for alarm采用的是非谓语结构.
从句就是there be句型放在从句的时候,谓语变为非谓语时用到.����͵��е���£��ܲ���˵��ϸ�㣬�ҵ��ӱ����鷳�ˡ�����Ҳ����˵�����ﲻһ��Ҫ������� ��������DZ�ʾ����ģ�ǰ���ǰ���״��Ӿ䣬����Ϊ��û���κ����죬��ص�����ķ��䡣 ��A��һ����ʾԭ���״��Ӿ��﷽����B��һ������ľ��Ӳ���ֱ����Ϊ�Ӿ䣬ȱ�����Ӵʡ�Dȱ�ٶ�Ӧ�������Ϊ�Ӿ�����there����������she ��һ�����Ա���there.����һ��Ӣ����﷨���������񡱡�
