1．(2016·江苏高考，27)If it ________ for his invitation the other day，I should not be here now.
A．had not been B．should not be
C．were not to be D．should not have been
A [考查错综虚拟语气。句意：要不是那天他邀请我，我现在就不会在这里了。虽然主句I should not be here now 是表示与现在事实相反的假设，但由the other day(那天，前些天)可知，if条件句是表示与过去事实相反的假设，故谓语动词用had not been。]
