虚拟语气 虚拟语气表达的是说话人的假想、推测、怀疑或愿望等,而不是客观存在的事实。 虚拟语气用在宾语从句中 1. 在wish后的宾语从句中 wish表示不能实现的愿望,意为“可惜……,……就好了,悔不该……,但愿……”等。常用于下列三种情况: (1) 表示现在不能实现的愿望,从句的谓语动词用动词过去式(be动词用were)。 例如: I wish Henry were as good and gentle as before. (2) 表示将来不能实现的愿望,从句的谓语动词用“would / should / could / might + 动词原形”。 例如: I wish you would go with us tomorrow. (3) 表示过去不能实现的愿望,从句的谓语动词用“had + 过去分词”或“would / could + have + 过去分词”。 例如: I wish we had come early yesterday. 2. 在would rather后的宾语从句中 would rather表示“宁愿,宁可”。后接从句时,从句中的谓语动词用过去式表示与现在或将来事实相反,用过去完成式表示与过去事实相反。 例如: I’ve spent too much money travelling. I’d rather I hadn’t. 3. 在suggest, demand, insist, request, order等动词后的宾语从句中 在suggest, demand, insist, request, order等动词后的宾语从句中,谓语动词用“should + 动词原形”,其中should可以省略。 例如: The boss insisted that everyone (should) attend the year-end party. 虚拟语气用在if条件句中 1. 表示与现在事实相反的假设,条件状语从句的谓语动词用动词过去式(be动词用were),而主句的谓语动词用“would / should / could / might + 动词原形”。 例如: If you were the only person to know this, would you spread the word? 2. 表示与过去事实相反的假设,条件状语从句的谓语动词用 “had + 过去分词”,而主句的谓语动词用“would / should / could / might + have + 过去分词”。 例如: Alice wouldn’t have seen me if I hadn’t waved to her. 3. 表示与将来事实相反的假设,条件状语从句的谓语动词用“动词过去式(be动词用were)”、“should + 动词原形”或“were + 不定式”,而主句的谓语动词用“would / should / could / might + 动词原形”。 例如: If it should (were to) rain tomorrow, they would be very unhappy. 虚拟语气的其他用法 1. 在if only后 谓语动词用一般过去时表示现在没有实现的愿望,用过去完成时表示过去没有实现的愿望,常译为“要是……就好了,但愿……”。 例如: If only Cindy had taken my advice! 2. “It is (high / about) time + that从句”中 从句中的谓语动词通常用一般过去时,也可用“should + 动词原形”(should不可省略),但不如用一般过去时普遍。 3. 含有without, but for, otherwise等词的句子中,有时也需用虚拟语气。 例如: Without air, there would be no living things on the earth. But for Miss Yang’s encouragement, I couldn’t have made so much progress. |
