注意:此用法如果出現(xiàn)在賓語(yǔ)從句中,即使主句是過(guò)去時(shí),從句謂語(yǔ)也要用一般現(xiàn)在時(shí)。
例:Columbus proved that the earth is round..

【比較】
1. Now I put the sugar in the cup. 2. I am doing my homework now.
第一句用一般現(xiàn)在時(shí),用于操作演示或指導(dǎo)說(shuō)明的示范性動(dòng)作,表示言行的瞬間動(dòng)作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是進(jìn)行時(shí)的標(biāo)志,表示正在進(jìn)行的動(dòng)作的客觀狀況,所以后句用現(xiàn)在進(jìn)行時(shí)。
