Question

She speaks as if she ____on the spot.

A．was

B．were

C．had been

D．is

Answer 1

B

试题分析：考查虚拟语气：在as if/as though引导的状语从句中，谓语动词多用倒退一个时间段的方式来表达虚拟语气。和现在情况相反用一般过去时，和过去时间相反用过去完成式，这题因为主句是she speaks所以是和现在相反，用一般过去时，虚拟语气中be动词用were。句意：她说话的样子好像她在现场。选B。
点评：在as if/as though引导的状语从句中用法：谓语动词多用倒退一个时间段的方式来表达虚拟语气。例如： The man speaks as if he were a foreigner./The speaker told us a lot about that country as though he had been there many times.注：as if/as though从句中不一定都要用虚拟语气。如果情况真实性、可能性很大，就要用正常时态来描绘。例如：It looks as if it is going to rain.天看起来象要下雨。（下雨的可能性很大。）
