重點語法
現(xiàn)在分詞和過去分詞作賓語補足語
1.現(xiàn)在分詞作賓語補足語和賓語之間存在邏輯上的主謂關(guān)系,強調(diào)動作在進行。常用在catch,feel,find,have,hear,keep,set,observe,see,watch等動詞后。
The next thing he saw was smoke rising from behind the house.
接下來他看到的是煙霧從房子的后面冒出來。
The man was fired because he had been found smoking in the kitchen.
那個人被解雇了,因為他被發(fā)現(xiàn)在廚房里吸煙。
2.及物動詞的過去分詞作賓語補足語與賓語有邏輯上的被動關(guān)系,表示被動意義或已完成意義,有時候兩者兼而有之。不及物動詞用作賓語補足語時,與賓語沒有邏輯上的動賓關(guān)系,只表示動作的完成或狀態(tài)。
When I opened the door,I found the ground covered with snow.
當(dāng)我打開門時,我發(fā)現(xiàn)地面被雪覆蓋著。
