虛擬條件句的三種基本類型是與現(xiàn)在事實(shí)相反、與過去事實(shí)相反、與將來(lái)事實(shí)相反。1、與現(xiàn)在事實(shí)相反若與現(xiàn)在事實(shí)相反，條件從句的謂語(yǔ)用過去式（be通常用were），主句謂語(yǔ)用“should（would，could，might）+動(dòng)詞原形”。2、與過去事實(shí)相反若與過去事實(shí)相反，條件從句的謂語(yǔ)用過去完成時(shí)（had+過去分詞），主句謂語(yǔ)用“should（would，could，might）+have+過去分詞”。3、與將來(lái)事實(shí)相反若與將來(lái)事實(shí)相反，條件從句的謂語(yǔ)用過去式（be通常用were），主句謂語(yǔ)用“should（would，could，might）+動(dòng)詞原形”。擴(kuò)展資料寫虛擬條件句的注意事項(xiàng)：1、主句謂語(yǔ)中的should主要用于第一人稱后，其中would表示結(jié)果，might表示可能性，could表示能力、允許或可能性。2、對(duì)于與將來(lái)事實(shí)相反的情形，需注意：（1）與將來(lái)事實(shí)相反實(shí)為對(duì)將來(lái)情況的推測(cè)；（2）此用法中的條件從句謂語(yǔ)除用過去式外，有時(shí)也用“should+動(dòng)詞原形”（表示可能性極小，常譯為“萬(wàn)一”）或“were to+動(dòng)詞原形”（表示與將來(lái)事實(shí)相反的假設(shè)）；3、當(dāng)條件從句使用“should+動(dòng)詞原形”這樣的謂語(yǔ)時(shí)，主句謂語(yǔ)除可用“should（would, could, might）+動(dòng)詞原形”這樣的虛擬語(yǔ)氣外，也可用直陳語(yǔ)氣或祈使語(yǔ)氣。
