1，虚拟条件句的三种基本类型

虚拟条件句的三种基本类型是与现在事实相反、与过去事实相反、与将来事实相反。1、与现在事实相反若与现在事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should（would，could，might）+动词原形”。2、与过去事实相反若与过去事实相反，条件从句的谓语用过去完成时（had+过去分词），主句谓语用“should（would，could，might）+have+过去分词”。3、与将来事实相反若与将来事实相反，条件从句的谓语用过去式（be通常用were），主句谓语用“should（would，could，might）+动词原形”。扩展资料写虚拟条件句的注意事项：1、主句谓语中的should主要用于第一人称后，其中would表示结果，might表示可能性，could表示能力、允许或可能性。2、对于与将来事实相反的情形，需注意：（1）与将来事实相反实为对将来情况的推测；（2）此用法中的条件从句谓语除用过去式外，有时也用“should+动词原形”（表示可能性极小，常译为“万一”）或“were to+动词原形”（表示与将来事实相反的假设）；3、当条件从句使用“should+动词原形”这样的谓语时，主句谓语除可用“should（would, could, might）+动词原形”这样的虚拟语气外，也可用直陈语气或祈使语气。
