<例句> I wish I knew what was going to happen. 但愿我知道將要發(fā)生什么事情。
<語法分析> 在某些動詞后面的賓語從句中需要用虛擬語氣,在wish后的賓語從句中謂語主要有兩種形式,即用過去式表示現(xiàn)在情況和用相當(dāng)于過去完成時(shí)的形式表示過去的情況。此外在would rather (sooner), suggest, demand, insist和ask等詞后面的賓語從句總也包含有虛擬語氣。虛擬語氣還可在主語從句、表語從句、同位語從句中和某些狀語從句中使用。謂語有時(shí)用虛擬語氣,特別是在由as if, as though等引導(dǎo)的狀語從句里,謂語形式和一般虛擬語氣差不多,表示現(xiàn)在的情況時(shí)用過去虛擬語氣,表示過去的情況時(shí)用完成形式。
