Though he knows little about the country,he talked as if he ____everything about it. A.knows B.should know C.know Dknew
解题思路： 如下
解题过程：
选D。 当说话人认为句子所述的不真实或极少有可能发生或存在的情况时。从句虚拟语气动词时态的形式如下： （1）如果从句表示与现在事实相反，谓语动词用一般过去式。 eg: You look as if you didn’t care.你看起来好像并不在乎。 He talks as if he knew where she was. 他说话的样子，好像他知道她在哪里似的。 （2）如果从句表示与过去事实相反，谓语动词用“had+过去分词”。 eg: He talks about Rome as if he had been there before. 他说起罗马来好像他以前去过罗马似的。 The girl listened as if she had been turned to stone. 那个女孩倾听着，一动也不动，好像已经变成了石头似的。 （3）如果从句表示与将来事实相反，谓语动词用“would/could might+动词原形”。 eg: He opened his mouth as if he would say something. 他张开嘴好像要说什么。 It looks as if it might snow.看起来好像要下雪了。
最终答案：略
