非謂語動詞是什么意思

非謂語動詞顧名思義就是不是動詞但又跟動詞有關聯(lián)。簡單說來有三種:to do, doing, done.

1. to do表示主動意義，指將來，偶爾一次性發(fā)生的事;可以作除了謂語以外的任何成分。它的變形有:to be done; to be doing; to have done; to have been done.

2. doing 表示主動意義，指現(xiàn)在，正在發(fā)生或持續(xù)發(fā)生的動作;可以作除了謂語以外的所有成分。可變形為:being done; having done; having been done

3. done 表示被動完成。只能作表語，狀語，定語，補語。無變形?？梢耘chaving been done 互換。 舉例:to see is to believe. seeing from the hill, we can enjoy a wonderful view. seen from the hill, the city looks wonderful.
